2014 Civil Engineering Internship Summary

Article 1:

After these days of internships, through practice, I learned a lot of practical knowledge, civil engineering internship summary. Through personal contact, I have observed the construction process of the whole house at a close distance, and learned a lot of specific construction knowledge that is very applicable. This knowledge is often rarely touched at school, rarely paid attention to, but it is very important. Basic knowledge.

First, just arrived at the construction site, causing confusion

Before going to the construction site, I have already had a huge understanding of the construction site, but I am confused about some specific links, such as the production of stirrups, the binding of steel bars, the prefabrication of concrete test blocks, the production of foundation caps, etc. only on site. Can you see it. How to pour the concrete of the beam, slab and column of the house. Also need to be on the spot to understand. What is the form and content of the construction plan and construction organization design? What is the shape of the crack in the floor of the C1 and B4 buildings, whether it exceeds the defined width and whether it will affect the structure and which effect. It is urgent to understand. The form in which the supervisory unit manages the construction unit and how to coordinate the relationship between the construction unit and the construction unit. It is also one of my confusions. And hope that this internship will make me feel good.

Second, the internship harvest, experience and experience

First of all, one of the biggest gains of this internship was to learn to adapt to the environment. Through this internship, I adapted to the construction site. With this period of exercise, there is a perseverance to work hard without asking what to do in the future. There is also a way to know how a supervisor on the construction site should communicate with the construction party and the construction party.

Secondly, through this internship, I have a deeper understanding of the combination of theoretical knowledge and practical experience of engineering. It should be said that the professional knowledge learned at school is theoretical and somewhat different from reality. In the process of reviewing the second phase of the building materials market, combined with the experience of the atlas and previous lectures, the repeated research has greatly improved the ability of reading and mapping; When the remaining amount of engineering works. Let me have a new understanding of the detailed structure of the house, know how the construction of the house is composed, and deepen the understanding of the concept of the book; when the second phase of the project starts, there is an opportunity to supervise the construction party with the potter The review of the elevations brought me into contact with the level and total station, and reviewed some of their methods of use; in the process of participating in the internship, we understood that our main task is management. Information management is an important part of the management process. The sending and receiving files of the past are all forms of effective management of the construction party. Also improved their file management capabilities.

Finally, one of the important purposes of this internship was to write a small paper on concrete cracks. The site just gave me this opportunity. Because of the cracking of the C1 and B4 buildings, there are materials and data provided by the testing unit. After observing, studying the materials provided by the testing unit, and analyzing the three processes, it becomes an important part of the content of the small paper.

At the same time, I found that many things on the spot are not consistent with the books.

The construction site is confusing in terms of contract and on-site management. In the case of individual projects that have not been tendered, the construction unit will start construction of the construction unit, and the construction unit's construction strength is weak and the construction team is complicated. For example, the door and window project of the first phase did not submit any information before the start of construction. There were many construction teams that were separately subcontracted by Party A. The cross-operation was complicated and lacked unified management, which led to a situation where the site management was chaotic and due to personnel. And the equipment can not meet the construction requirements and the progress is slow.

Third, deepen the understanding during the internship process

1. Understanding of cracking of floor slab

First of all, the cause of cracks in the floor. There are many factors that cause cracks, and cracks are ubiquitous in concrete structures. Each building has cracks, but some cracks are tiny and difficult to observe. There are two main types of cracks. One type is general plastic shrinkage cracks, dry shrinkage cracks, etc. due to materials, climate, etc. Such cracks generally have little effect on the bearing capacity and can be treated generally or not. Another type of crack obviously affects the bearing capacity of the beam. As the crack expands and extends, the steel reaches the yield strength and the strain in the compression zone increases. Large, the beam stiffness is greatly reduced, and the components tend to be destroyed. Such cracks must be reinforced and strengthened early to meet structural safety needs.

Second, the floor cracks are treated. The treatment methods for cracks caused by temperature and humidity are as follows: 1 Surface treatment method: including surface application and surface adhesion method. The surface application range is fine and shallow cracks in which the slurry material is difficult to be poured, and the hair depth is not up to the surface of the steel bar. , watertight seams, non-stretching cracks and cracks that are no longer active. The surface patching method is suitable for anti-seepage and plugging of large-area water leakage; 2 filling method. The crack is directly filled with the repairing material, and the operation is simple and the cost is low. 3 grouting method. Cracks with a width of less than 0.3 mm, shallower depths, or fillings in cracks, cracks that are difficult to achieve by grouting, and simple treatment of small-scale cracks may be opened with a V-groove and then filled. This method can be applied in a wide range, from fine cracks to large cracks, and the treatment effect is good.

Non-penetrating cracks with a width of >0.3mm can cause corrosion of steel bars, affecting the long-term bearing capacity of the structure and affecting the safety of the crack structure. Structural reinforcement methods such as enclosure reinforcement method, steel hoop reinforcement method, affixing reinforcement method and carbon fiber reinforcement method can be adopted. This method is structural reinforcement and must be approved by design verification.

1 enclosure reinforcement method. When the surrounding dimensions permit, the reinforced concrete ferrules are wrapped on one side or several sides of the structure to increase the steel bars and sections to increase the bearing capacity; if the cracks in the components are serious, the cracks are not broken or the one side is broken, and the cracks will be cracked. The part of the steel protective layer is cut and the outer layer of the steel mesh is laid out; the large equipment foundation is generally treated by adding steel band and increasing the tensile strength of the ring.

2 steel hoop reinforcement method. U-bolts or steel ferrules are applied around the structural cracks to tighten the components to prevent crack expansion and increase the rigidity and bearing capacity of the structure. When reinforced, the steel ferrule should be in close contact with the concrete surface to ensure joint work.

3 affixed to the reinforcement method. The modified epoxy resin and the binder for the steel plate or the section steel are bonded to the surface of the crack portion of the component to make the steel plate or the section steel and the concrete work together. Before bonding, the surface of the steel is sandblasted and rusted, and the thickness of the bonding layer is 1-4 mm.

4 carbon fiber reinforcement method. Carbon fiber cloth reinforcement technology uses carbon fiber cloth and special structural adhesive to strengthen the building components. The carbon fiber cloth used in this technology is about 10 times stronger than ordinary secondary steel. It has high strength, light weight, corrosion resistance and durability. Etc. The thickness is only about 2mm, which basically does not increase the cross-section of the component, and can ensure that the carbon fiber cloth works together with the original component. After reading several papers and testing and reinforcement materials on the C1 floor, the carbon fiber reinforcement technology was carefully studied. It was found that the carbon fiber reinforced plastic has high strength and good effect; after reinforcement, it can greatly enhance the corrosion resistance and durability of the structure; Basically, it does not increase the structural weight and section size; it has good flexibility, easy cutting, wide practical range; convenient construction, easy operation, good economy and short construction period. The principle and construction of the reinforcement are studied and will be used as a direction for future papers.

2. Understanding of communication with people

In the course of work, I learned to be friendly with my colleagues, humbly consulted them, learned to communicate with the construction and construction parties, especially the communication with the construction party, to show that we are serving them. Instead of letting them obey management, I gradually gained their recognition and continued to take on the tasks they gave me. Tasks range from simple to complex, and the ability is constantly improving.

3. Understanding of supervision work

Although the supervision work in the book is three control, three management, and one coordination, the safe production and comprehensive organization and coordination in the actual work are the core contents. During the internship, I actively studied and read some of the supervision materials during the construction phase, including: supervision planning, supervision implementation rules, project progress plan, supervision engineer notice, supervision work contact list, supervision diary, supervision monthly report, site regular meeting file, etc. . Initially mastered the basic knowledge of engineering supervision work and the basic program of operation. Gradually familiar with the construction of the project. In addition, the construction organization design of the construction unit was read, and the requirements for each part of each process should be clearly stated according to the specifications. I used what I learned in my previous books outside of practice, and I paid special attention to what was not in the book but useful in practice. I learned a lot of useful things and deepened my understanding of supervision work.

Fourth, the shortcomings of existence and the direction of future efforts

1. Juguan: There are still many deficiencies in it. Sometimes, when exercising supervision, it is not very important to listen to the opinions of construction workers, and the work methods are not flexible enough; because of the narrow knowledge and understanding of the norms and supervision procedures Not thorough enough, resulting in a lack of management skills at work, can not coordinate work well; consider the problem is not comprehensive. I plan to learn more about management coordination and on-site technical capabilities in future work. It is necessary to be rigorous in words and deeds, to have a basis for speaking, and to pay attention to the scale when making suggestions to the construction unit; more work is needed in file processing and writing to ensure the accuracy and high generality of the writing.

2, professional aspects: 1 is not solid enough to grasp the theoretical knowledge. Such as: curing time of concrete and mortar test blocks, curing time of test blocks and the extent to which they should be vibrated, curing temperature and curing time after concrete pouring. 2 The ability to be familiar with drawings is poor, and it is difficult to imagine a three-dimensional appearance on a flat graphic. It is impossible to clearly determine the right or wrong of construction. 3 With the update of construction specifications, some of the latest construction specifications are not known, so it is difficult to judge the right or wrong of construction. 4 For some construction sequences, it is still unclear, and some operations of the construction process are not understood.

3. In the future direction, we must first strengthen our management ability and improve some improper working methods. Secondly, we should be familiar with the construction specifications, understand some theoretical knowledge in depth, and be aware of the acceptance of construction quality. The last step is to familiarize yourself with the relevant software and complete a paper on cracks in the floor based on the data provided by the actual project.

V. Summary

This internship gave me a certain understanding of the basic knowledge of construction and information management, and opened a way for learning professional knowledge in the future. Especially for concrete cracks, as a direction for future research, I carefully read through relevant papers and test reports, and learned a lot of knowledge that I had never known before by asking Fei Lao and potter. I also learned some simple and clear methods for judging the quality of construction through Fei Lao. Although this is the longest time I have been on the construction site this month, the harvest is the most. It has far-reaching implications for my future work and study.

Fourth, the internship overview

1. The importance of interpersonal relationships in the construction industry.

Interpersonal relationships are extremely important in construction operations. Good interpersonal relationships can handle all kinds of problems that occur during the construction process, in order to achieve more with less.

In the construction unit, almost everyone understands the importance of dealing with interpersonal relationships, but in spite of this, most people don’t know how to deal with interpersonal relationships. Even a lot of people mistakenly think that flattering, flattering, and giving gifts In order to handle interpersonal relationships. In fact, the key to dealing with interpersonal relationships is that you must have an open personality and be able to truly appreciate others and respect others.

When you get along with your boss, colleagues, and subordinates, if you can objectively discover the merits of others and sincerely respect and appreciate others, your interpersonal relationship will be like a duck. However, some people think that they have no talents. They see that their boss is not as good as their own. They think that their superiors are not as good as themselves. They look down on their boss from the bottom of their hearts, complain privately to their superiors, and do not cooperate with their superiors at work. As a result, their relationship with their superiors is not handled. Well, let alone colleagues and subordinates, such people will inevitably eat their own fruits, and it is difficult to survive in society.

A person who knows how to treat people with respect and respect for people will have a good time. Others will appreciate and respect him as well. A team that advocates appreciation and respect for people will be a harmonious family. Every member of the team appreciates and respects others. Every member is also appreciated and respected by others. Every member will feel comfortable, so the team's cohesiveness will improve. This is very important for the construction team.

Discuss the choice of construction team from interpersonal relationships. Thinking at the height of a project manager, such a problem is very critical. The quality of the construction team will directly affect the quality of the construction project and affect the economic interests of the project manager. A good construction team can coordinate the various projects, and the same bad construction team can make a perfect project. According to my observation and thinking, I have a preliminary understanding of the construction site of our internship. The construction team has a very good cooperation. From the construction of the site, it can be clearly seen that the construction teams and the workers have a lot of coordination, encounter problems, and work together. Work together to solve. Therefore, in the on-site construction, interpersonal relationships are extremely important, which is also my thinking after the internship.

2. The importance of construction experience.

After the internship, I learned a word: "If you do one thing together, one is a dull person who has done this for ten years, and the other is a very intelligent person who has no experience in this field. There is no doubt that the former will definitely win. "In fact, everyone is smart, not to see if the person did a good job for the first time, but to see what he changed after the first time. It’s always the same sentence, people will fall, then, must sum up why they fall, and then refuse to make the same mistake again next time. Experience is what everyone gets when they do something. The question is how to use the experience gained to get better results. I asked myself, I know and master the new things in general, but the advantage is that I can improve in the experience to get something that is good for myself. On the contrary, the biggest shortcoming of a man who is familiar with me is that he does not know how to sum up, refuses to admit that the fall is because of his own problems, and thus does not get any experience that is beneficial to him, and then continues to fall next time.

In the construction work, this kind of on-site experience is extremely important. From my internship analysis, I think that a civil engineering staff member can do a good job and be successful. There are many reasons for this, including his own personal IQ. More important to the focus of things, such as the proficiency of things, in fact, is the construction site experience.

3. The importance of professional quality.

I think that college students who are about to graduate will be a competent worker in the future. First, they must abide by morality. A very important aspect of the construction of professional ethics is to cultivate and establish the moral responsibility consciousness of the subject of moral behavior, that is, the problem of moral subject consciousness that people pay more attention to in these years. If you can't do the morals that a college student must abide by in the labor position, what do you do about it? With the development of modern social division of labor and the degree of specialization, the market competition is becoming increasingly fierce. The professional concept, professional attitude, professional skills, professional discipline and professional style are increasingly demanding. We must vigorously advocate professional ethics with the main content of "love and dedication, honesty and trustworthiness, fairness, service to the people, and dedication to society", and be a good builder in the work.

The construction of college students' professional ethics is like building a building. If the foundation is unstable, how can we prop up a building? So the university students we are graduating are like the foundation, we must firmly stay at the bottom of the society and make a good stability. The cornerstone of that will enable us to move in the right direction, which will enable us to make a difference in the future. I believe that as long as we work hard, we will definitely be the cornerstone, so we must start from ourselves and cultivate ourselves. Responsibility for work, moral sense, exerting our own sense of responsibility, and earnestly fulfilling professional ethics. Only in this way can we do our work well and be fine.

4. Internship harvest at the construction site.

In the past one month of production internship, I have learned a lot of things, and I have personal experience from different aspects of construction. However, since the pile foundation had been finished, it was not able to reach the piling, but after the inquiry to the master, I learned the piling process and process.

4.1 Learn important construction projects.

The entire concrete structure project includes basic engineering, steel engineering, formwork engineering, and concrete engineering. The following will summarize the knowledge I learned during the internship and the projects I participated in:

4.2 Understand the basic project.

Since the foundation is the most critical part of the whole building, it is also the top priority of the project. It is essential to do a good foundation. The foundation works include earth excavation, piling, broken pile treatment, construction of foundation caps, foundation beams, etc. . Due to the earthwork excavation and piling of the entire project, it has basically ended, and it was not accessible during the internship. So the following is only a brief introduction. Due to the poor soil quality and thick muddy soil, a large area of ​​broken piles occurred during the piling process. Many buildings have seriously affected the progress of the project due to broken piles. In the course of this internship, I learned a lot of methods for breaking piles.

4.3 Recognize the steel works.

Reinforced steel is the skeleton of the reinforced concrete structure, which is integrated with the concrete by the gripping force. Reinforcement engineering is one of the three major projects of concrete structural engineering.

The classification of steel bars can generally be classified according to the different production processes, the diameter and the strength of the steel bars. The production process can be generally divided into hot-rolled steel bars, cold-rolled steel bars, cold drawn steel bars, and cold drawn steel bars. According to different diameters, there are mainly the following types of steel bars: 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, etc. In terms of strength, steel bars can be classified into HPB235, HPB335, HPB400, and RRB400 grade steel bars. Among them HPB235 and HPB335 are the two most commonly used steel bars.

Because the quality of the steel bars is difficult to inspect after the concrete is poured, the steel works are concealed works, which need to be strictly inspected during the construction process and establish the necessary inspection and acceptance system. In order to ensure the normal operation of the concrete structure during the use phase, the specification and position of the steel bar must be consistent with the structural construction drawing during the construction of the steel bar.

Steel bars in the project often have to be connected due to insufficient length or due to construction process requirements. Therefore, the connection of steel bars is an important link in the steel works.

4.4 Recognize the template project.

Formwork engineering of concrete structures is a very important part of concrete forming construction. The template we are talking about actually consists of two parts, one of which is the formwork that forms the shape and design dimensions of the concrete member: the second is the support system that guarantees the shape, size and spatial position of the formwork. The formwork should have a certain strength and rigidity to ensure that the concrete does not damage or deform under the weight of the concrete, the construction load and the side pressure of the concrete. The support system not only guarantees the accuracy of the spatial position of the formwork, but also bears the weight of the formwork, concrete and construction load. Therefore, it should also have sufficient strength, rigidity and stability to ensure that it does not sink under the action of the upper lotus load. No deformation, no damage.

Templates are also very different in terms of materials and types. Generally, it can be divided into this template, steel template, and plywood. Most of the steel stencils are used in this project, so it is not easy to deform.

The function of the template is that during the construction of the structure, the concrete just mixed out from the mixer is in a liquid state, and needs to be poured in the model number of the same shape and shape as the member, so that the desired structural members can be formed after the concrete is hardened by condensation. A formwork is a model that shapes a reinforced concrete structure or component.

The support system of the formwork is to ensure the shape and position of the formwork panel, and to withstand the temporary structure of the formwork, steel bars, new concrete weight and construction load. The vertical support of the formwork mainly consists of a loosely assembled pipe support, a steel strut that can be used independently and with height adjustable devices, and a door frame.

Before the template is installed, the design calculation of the template is also required. Commonly used stencils generally do not need to be designed or checked within their scope of application. Generally, experienced contractors and workers know how to install them. However, for some special structures, templates for new systems or general templates that are outside the scope of application, they should be designed or checked. For example, a large cap, tower crane foundation, etc., otherwise it is easy to expand the mold.

4.5 Recognize concrete works.

Concrete engineering includes construction, transportation, pouring, maintenance and other construction processes. Each construction process is related to each other and affects each other. Improper construction of any process will affect the final quality of concrete engineering.

The preparation of concrete involves the preparation of concrete and the agitation of concrete, each step being crucial. The preparation of concrete also includes the design coordination of concrete and the construction mix ratio of concrete. The construction mix ratio is based on the design ratio of the laboratory to increase a value and has a 95% strength guarantee rate. Concrete construction ingredients must be accurately measured to ensure that the concrete being mixed meets the design and construction requirements. The deviation shall not exceed the specification. The difference between the construction mix ratio and the experimental mix ratio is the difference in water content. Because the concrete strength value is very sensitive to changes in the water to cement ratio. Due to the actual moisture content of sand and stone in the laboratory when testing concrete. In order to ensure accurate water-cement ratio of on-site concrete, the water consumption should be adjusted according to the actual moisture content of sand and stone on site.

For concrete mixing, to obtain uniform concrete, the raw materials must be thoroughly stirred to thoroughly mix the raw materials. The mixing of concrete in the project generally adopts mechanical agitation. Generally, attention should be paid to the control of the mixing time and the control of the feeder time.

Concrete pouring is the most important part of concrete engineering. Only qualified pouring can ensure the strength of concrete. The compactness meets the design requirements, and the integrity and durability of the structure can be ensured. The size can be accurate to ensure the concrete after demoulding. The surface is smooth and smooth.

Before the concrete is poured, the acceptance of the concealed works should be done, and the size of the formwork, the axis and its bearing capacity and stability should also be checked. The quality of the pouring is also closely related to the technical level of the pouring workers. If the vibration is insufficient during the pouring process, it is easy to produce segregation, and it is easy to produce honeycomb, pockmark, and even lacing. The indwelling of the construction joint is also a special process of concrete pouring. For some reasons, the whole structure cannot be continuously poured, and the stopping time may exceed the concrete setting time, and the construction joint should be pre-determined in the appropriate part. Generally, the construction joint should be left in the part where the structure is less affected by shearing, and the convenience of construction should be considered when applying.

5. Learn common problems on the construction site.

5.1 The electric box configuration of the mixer and steel processing factory may not be complete enough, there is always the danger of electric leakage, and the danger of electric shock, it should be checked in time.

5.2 If the scaffolding is bamboo, the class owner should select the quality of the bamboo, because as the number of layers increases, the load increases, and the danger is greater, especially the small crossbar.

5.3 If the foundation of the scaffolding and the formwork frame is not very stable, there is a possibility of collapse, especially in rainy weather.

5.4 At the construction site, if there are too many wooden houses, they will often be irregular. Workers will build houses everywhere, which makes the workers' lives threaten.

5.5 In the process of building a wall, if the wall is to be cornered or intersected, the two walls should be built together. In the process of staying, you can leave the slanting squat. If you want to stay straight, you must stay in Yangshuo. There is a tie-bar, and you can't leave a haze.

5.6 In the process of concrete construction, pay special attention to the mix ratio of concrete, pay attention to maintenance when it is hot.

V. Summary of production internship

During the period of the company's internship, it is a process of combining theory with practice for me. Under the guidance of the construction site construction technicians and technical leaders, and my own efforts, I actively participate in the work and let myself be on the whole foundation. Practice, the construction of the standard layer has a deep understanding and mastery. Moreover, he has a deep understanding and understanding of all aspects of civil engineering, and consolidates the knowledge in books, applies the theory to practice, and enriches his own theoretical knowledge from actual construction. The whole internship process was short, but let me know how to be a good technician. The whole internship process also allowed me to discover the deficiencies in my theoretical knowledge, and also made myself full of motivation for future studies. Although the construction site is a bit bitter, but also let himself understand a sentence: "eat hard and bitter, and be a person."

In just four weeks of internship life, I learned a lot of things. The original kind of heart is not proud of it. Instead, I am working hard to study hard. When I set my own mentality, from the passive state of social work to the active state of adapting to society, with a relaxed mood and plenty of energy to return to the intense study work, I suddenly felt this way. : In just one month, it seems that the thought has been sublimated again, and there is another sentiment in life.

This internship made me realize that reading is a way to broaden my horizons of knowledge, but more practice, smooth in the real world, touch the pulse of society, set a position for myself, is also an excellent way to improve their overall quality. select.

VI. Comments and suggestions

I am very grateful to Liaoning Jindi Construction Engineering Group Co., Ltd. for providing me with a good internship opportunity. I also let myself contact the scene for the first time and contact the society. I not only learned how to combine theory with practice, but more importantly, let I learned how to be a person. After a four-week internship, I have matured a lot, but there are some problems in getting knowledge. I will summarize three comments and suggestions on this internship below.

9.1 During the internship process, some exchange meetings can be held as appropriate. For example, in the middle of the internship, some experience exchange meetings can be held in groups. The on-site instructor can guide the students, so that the students can make the internship for the second half more purposeful. There is no such thing as a purposeless internship.

9.2 Students can find a free time, visit each other's projects and see how others have done it. This will prevent them from becoming a frog at the bottom of the well. It can also promote communication, take its essence, and discard its dross.

9.3 When conditions permit, the on-site teacher can go to the construction site to conduct investigation and guidance during the internship of the students. Not only can the students be lazy, but also constructive guidance can be given to the students to make our internship more efficient.

Seven, the end of the production internship

Practice is the second classroom of university life, the source of new knowledge and development, the touchstone for testing truth, and the effective way for college students to exercise and grow. A person's knowledge and ability can only be effective in practice, in order to be enriched, improved and developed. For college students to grow up, they must be diligent in practice, combine the theoretical knowledge and practice they have learned, continue to learn in practice, continue to summarize, gradually improve, innovate, and improve their knowledge, ability, wisdom, etc. in practice. The comprehensive quality and ability of the factors are combined to lay a good foundation for the success of their own career.

Finally, I would like to thank the internship unit for providing me with this internship opportunity, as well as providing me with excellent teaching and living conditions. This production internship has benefited me for life. I will continue to study hard and strive to become a qualified builder soon!

Article 3:

Wood engineering is the general term for the disciplines, techniques and engineering of various types of engineering facilities. It refers to all kinds of engineering facilities related to human life and production movement, such as construction, road and urban route engineering, railway engineering, bridge engineering, tunnel engineering, etc., and also refers to the use of materials and equipment on the land. Engineering skills such as survey, design, construction, etc. Civil engineering is one of the pioneers of "clothing, food, housing, and travel" required for social and technological development; it has occupied a pivotal position in the citizen economy of any country.

As a college student who has just come into contact with professional knowledge, it is unscientific to assume that it is not scientific to directly contact deep knowledge before taking a professional course. To this end, the college deployed us to carry out this internship exercise, let us practice this self from practice. The professional to be engaged will gain a perceptual understanding and lay a solid foundation for the future study of professional courses.

The intense internship for more than a month has stopped, and I have had a lot of gains in this more than a month. After the internship is stopped, it is necessary to sum up it. First of all, through more than a month of internship, the symptoms of prostate cancer, through practice, I learned a lot of practical knowledge. The so-called practice is the only measure to test the true meaning. Through the side station, I have seen the construction process of all the houses in close intervals, and learned a lot of practical and concrete construction knowledge. This knowledge is often my little contact at school. Less attention, but it is a very important and very basic knowledge. For example, in the process of building a wall, if the wall is to be cornered or intersected, the two walls must be built together. In the process of staying in the stubble, you can leave the slanting squat. If you want to stay straight, you must stay in Yangshuo. And there must be a tie-bar, not a haze. In the process of concrete construction, it is necessary to pay special attention to the mix ratio of concrete, and pay attention to maintenance when it is hot. Through practice, I was able to face the construction staff face to face, public relations company, how to construct them, how to turn the model on the drawings into beautiful buildings, learned a lot of practical concrete construction knowledge and solved the problems encountered at the scene. This knowledge is often my little contact at school, speed reducers, and little attention, but it is a very basic knowledge. On the first day, the master went to the floor and reviewed the level of the second and third floors for the next few days until the end. In the building, I found a lot of cracks in the junction of some buildings. After the teacher's lecture reminder, plus the materials I collected, there have been many gains.

Now I am going to talk about the knowledge I have learned on the spot:

Phenomenon I. Crack

Causes of cracks There are many reasons for cracks in concrete. The important ones are the change of temperature and humidity, the brittleness and unevenness of concrete, the unfair structure, the failure of the original data, the deformation of the formwork, and the uneven settlement of the foundation. During the hardening of the concrete, the cement releases a large amount of hydration heat, and the internal temperature rises continuously, causing tensile stress on the surface. In the later stage of cooling, due to the restraint of basic or old coagulation, tensile stress will appear inside the concrete. A drop in temperature also causes a large tensile stress on the concrete surface. When these tensile stresses exceed the crack resistance of the concrete, cracks will appear.

Logo design

If the maintenance is not good, when it is dry and wet, the surface shrinkage deformation is bound by the internal concrete, and often leads to cracks. In reinforced concrete, the tensile stress is mainly borne by the steel, and the concrete only bears the compressive stress. In the plain part of the plain concrete or on the reinforced concrete, it is assumed that the tensile stress is present in the structure, and it must be borne by the concrete itself. In general design, it is requested that no tensile stress is exhibited or only a small tensile stress is exhibited. However, during construction, the concrete is cooled from the highest temperature to the stable temperature in the running era, which often causes considerable tensile stress inside the concrete. Sometimes the temperature stress can exceed the stress caused by other external loads, neurodermatitis, so the law of controlling the change of temperature stress is extremely important for the fair structural design and construction.

Specific measures: In order to ensure the quality of concrete works, prevent cracking, and improve the durability of concrete, accurate use of admixtures is also one of the ways to reduce cracking, such as the use of water reducing and cracking agents. In short, the early curing practice of concrete confirmed that most of the common cracks in concrete are surface cracks of different depths. The main reason is that the temperature gradient causes the temperature drop in the severe cold area to form cracks easily. Therefore, the insulation of concrete is especially important to prevent early cracks on the surface. Starting from the point of view of temperature stress, the insulation should reach the following requirements: 1) Prevent the temperature difference between the inside and outside of the concrete and the gradient of the concrete surface to prevent surface cracks. 2) To prevent the concrete from being extremely cold, the idea should be to make the minimum temperature during the construction period of the concrete not lower than the stable temperature of the concrete use period. 3) Prevent old concrete from being too cold to reduce the bondage between old and new concrete.

The early curing of concrete is also very important. Its important goal is to adhere to the appropriate temperature and humidity conditions to achieve the consequences of two aspects. On the one hand, the concrete is protected from unfavorable temperature and humidity deformation, and harmful cold shrinkage and drying are prevented. Shrink. On the one hand, the cement hydration is carried out smoothly, in order to reach the design strength and crack resistance. Suitable temperature and humidity conditions are interrelated.

Phenomenon 2, lashing of steel bars

On-site inspection and drawing comparison and master's lecture, I understand how to turn things on the drawings into real objects. This may require a process. In this process, I invented a lot of problems and now the joint picture is stated. It can be seen that the spacing of the stirrups is not in place. There are still many problems. For example, the steel bars piled up at the joints of the beam and the beam are not disposed of well. The position of the steel bars is obviously raised, and the weight is quickly and healthyly lost. When pouring concrete, it is easy to leak the ribs... Fortunately, there is no shortage. The phenomenon of ribs is produced. In their words, the status of steel bars can be wrong, but they can't be less gluten. If the gluten is less than the bottom, the expert group can easily know it with the instrument.

The specific solution: the steel manager is responsible and responsible, can not be numb, always urge the workers, such as the invention of the wrong to do!

Phenomenon 3, the elevation of the template is incorrect

This problem is not always generated, but it is very important! Some contractors have applied steel formwork in some places, the construction progress is faster, almost four days, to treat asthma, because of this advanced construction technology, this is also a small company. Unable to compare.

Specific measures: The elevation gap is within the ?cm scale, which is naturally solved by the concrete's own weight when pouring concrete; if it exceeds this category, it must be properly raised or lowered to support the request.

At the construction site, I have been exposed to a large number of workers. Although their culture is not high and their literacy is not high, their labor is hard work. Construction workers are a group we deserve to help, they are in a weak position. We should care for the disadvantaged people. After thinking about it, you know their misfortune and happiness, and radiotherapy, only to know their tenacity, only to realize their greatness. Assuming that our policies are more perfect, the rights of workers will be better protected. Then there will not be so many unpopular phenomena. Workers and migrant workers are also life-threatening, and they are also a complete social person with legal rights. They, paid, corporate image propaganda, they are helpless, they are almost unable to change their own destiny, but those of us who strongly sponsor them should give back to them to do something, film and television advertising production, to express gratitude, to show Their respect.

The unforgettable one-month internship stopped, and during this many months, I learned a lot and understood a lot of truths. Practice is the best test of scientific knowledge. It is only in the classroom that you can not control the scientific knowledge of the specific system, especially the application of the instrument. In the classroom, the theoretical knowledge we learn, assuming that it can't be applied dexterously in real life and work, then everything will be zero. Internship is to apply the theoretical knowledge we have learned in the classroom to actual combat. Therefore, we must be able to apply the appropriate knowledge of textbooks to become useful to others. We must adapt to the fast-growing society, be able to determine our own life coordinates, and be able to achieve our own. the value of life.
