Engineering survey internship, as a basic compulsory professional practice course for civil engineering majors, is of great importance to our students studying civil engineering. Learning measurement is not only the acquisition of the theoretical knowledge of books, but also the cultivation of our hands-on ability and the in-depth understanding of the textbook theory, as well as the experience of measuring the "from control to the broken parts, from the whole to the local, step by step check" The guiding principle of the principle of engineering measurement. The mastery of this skill will be of great help to the construction site in the future. After all, the opportunities given to students in domestic universities are far from enough to meet the needs of students. To this end, we must create the greatest intellectual benefits in limited opportunities. Of course, we can also improve our thinking structure and cultivate our spirit of cooperation and leadership by measuring the internship platform.

The internship was organized by the hospital, and the teachers personally led the team to guide the students to discuss the exchanges and complete the scheduled tasks. Professor Wu Zuhai served as our instructor this time. I often come to our dormitory to solve the problems encountered in the internship process and give us the experience in the work to stimulate our interest so that we will not be blind in the internship process. Weather is an important factor. During the rainy and sunny days, we need to seriously deal with the changes in climatic conditions often encountered in these site surveys. When it is raining and when the sun is strong on a sunny day, the requirement for the umbrella is that the instrument precedes the person; the parameter setting of the instrument such as the total station should follow the specifications in the specification; avoid the occurrence of problems such as foundation subsidence, and ensure the high efficiency and high quality of the measurement task. carry out. Weekly tasks are scheduled on Friday or Friday of the previous week, and the information is checked on weekends so that each of our students can better enrich their theoretical knowledge and check the problems that occur during the measurement process. Although this month's hard and rewarding engineering survey internship is over, it is really a test for us during these four weeks. During this period, we have been tired and tired, and we have sweet and happy. There are difficulties and obstacles during the period, and there are great gains. And more theoretical knowledge to improve the ability to practice. It’s no exaggeration to describe it in pain.

Before the start of the measurement internship, I carefully reviewed the textbooks of engineering surveys from beginning to end, so as to stand at the height of a theoretical person and do production practice.

The field internship takes the form of a simulated construction site, and the field is the west gate of the campus to the Century Building and a large area of ​​surrounding buildings. This simulation also has the advantage of simulation, which can comprehensively reduce the problem of the site site to a relatively small area, saving time and reducing internship costs. No matter what, the internship is a happy life, at least farewell to the strong radiation of the dormitory display, close to nature, the railway campus is more and more lovely in my eyes.

The first week of tasks are elevation measurements and traverse measurements. Elevation measurement is simple and easy to operate. The azimuth is determined by the coordinate azimuth. We have done it quickly and smoothly. Because the accuracy of the wire measurement is high, it is necessary to carry out more complicated data processing, but these do not affect the progress. The famous phrase of Bruce Lee is “fast, accurate.” There is no word because the instrument must be gentle and should be integrated with the instrument. Being one is the highest level of measurement. Don't forget the textbook knowledge at any time. If you have problems, you can refer to the textbook. You can ask the teacher and discuss with your classmates. A series of actions is a necessary condition for completing tasks efficiently. In the process of completing the process, I borrowed the knowledge of classroom learning. In the early stage of this task, I conducted an elevation measurement with a team member to participate in the traverse measurement with other team members. The calculation of various data in the whole process benefited a lot.

The second week of the mission is a partial topographic mapping. The mapping of the topographic map has higher requirements for the scaler. The quality of the running rule is directly related to the quality and progress of the results. I am self-recommended, picking up this burden, and also responsible for the operation of the part. The erection of the instrument is also a hard work, and must be solid. As mentioned before, this friend must be handed over to the instrument, and the instrument should be changed to achieve the ultimate harmony. Operate the instrument, and focus on the observation and record work throughout the measurement, and pay attention to the attention to detail. This task requires the active cooperation of everyone in our team to complete the smooth and fast, and the team members actively cooperate to finally complete the task quickly. In this task, I have worked as a coordinator, a mirrorman, a scaler, an inspector, and a draftsman. Every job is involved. It is inevitable that the measurement is inevitable, but it is not enough to hinder the pace of measurement. There are more courses, and the effective working time is shorter. It is more necessary to cooperate with the measurement. Last week's task was to put control points. Although the accuracy requirements were relatively low this week, due to the large amount of tasks, the work was sloppy. After the completion, the natural perception of topographic mapping has been greatly improved. The experience of selecting wire points has also been greatly advanced. The topographic map involves the application of cass software. The main drawing work is carried out by another team member. Of course, learning a software is also a Important harvest.

The third week of the task is the line test. Our team first took a step in the field and selected the route to take into account the economy and gold content. After the line selection is completed, the whole page is calculated. The internal page is calculated in a large amount. After we have calculated and carefully checked the confirmation, we will start the stakeout. The field work was done within two days, and piling was a hard work. In order to consider pedestrians, it took a lot of effort to plow the piles. Longitudinal measurement of the last day, cross section measurement. For these two external page measurements, we explored the instrument operation and the check and verification steps, then started the measurement, and finally processed the data plot. In this task, I actively participated in and fully understood and deepened the knowledge of all aspects of theory and practice of the cross-section.

In the fourth week, our internship was measured by the bridge control network. Our team completed the task in three days. We did it very quickly and it was very easy to complete. At the same time, I felt that the internship enhanced my confidence and felt that the internship was very effective. During the period, we did a good job in angle estimation, bridge control network stakeout, etc. However, when using the direction method to observe the angle actuarial, because the reading is not stable enough, our error is too large, repeated measurements, but I think the internship stage It is normal to have some small mistakes, which can better promote our mission. I have actively participated in the various steps in this task, and have greatly improved the proficiency of instrument operation, and the data processing speed and quality have increased a lot.

The completion of all the tasks in this four weeks has devoted a lot of effort to the five people in our group. A measurement internship is complete and complete. It is not enough to rely on the strength and concept of one person. Only the cooperation and unity of the group can make the internship fast and efficient. The completion. Collaborative issues are also common during the internship process, but we have a common goal, “faster and stronger”, so we finally stand on a battleline and break through the city. Therefore, as long as we five people cooperate sincerely, exchange ideas and understand each other, all problems will not be a problem. Sometimes the measurement period comes back late, the canteen can't catch up, only eat instant noodles, etc.; the outer page is tired during the day and comes back to process the data at night. There is sweetness in the tired, and there is joy in the bitterness. Each of us is full of passion every day, and the accomplishment of the task is fruitful.

I deeply realized that through this actual measurement internship, I learned a lot of real things, such as the more skilled operation of the experimental instruments, learned the measurement of the broken parts, the measurement of the wires and the mapping of the topographic map, the bridge control network The measurement and other things that can't be learned in the classroom greatly improve the ability of hands-on and brain-moving, and also expand the ability to communicate and cooperate with classmates.

However, there are some lessons: the exhibition point is very important. The quality of the exhibition point determines the speed of the measurement; the leveling of the experimental instrument has a great influence on the error of the experimental data; both the leveling and the horizontal angle measurement need to check the closing difference. The difference must be re-measured after the difference is exceeded; the thickness of the drawn grid pencil should be checked repeatedly to reduce the error according to the regulations. The grid line has a great influence on the topographic map; the cooperation of the group members is very important, and the atmosphere of the internship group is greatly affected. The progress of the experiment.

In short, I have a deep understanding of this measurement internship. It not only provides me with a platform to improve my ability in all aspects, especially the control to the broken department, which is enough to promote various scientific fields, such as Mr. Qian Xuesen’s systematic science, which does not emphasize these structures. The importance of the framework also involves the habit of thinking, from the point of connection, from the line to the face, and then the body. Grasping the key factors is also a way of thinking that is optimized. Internships have benefited me a lot, improved teamwork and coordination, collective sense of honor, hard work, hard work, and the need to pay attention to public property and custody of equipment. These have added practical experience to work in the future. The foundation has achieved the intended purpose. I learned cass and gradually became proficient in office, auto cad, and cad-based cass software. At the same time, when calculating, I used matlab software programming for some complicated calculations, and the solution was quick and accurate. Special thanks to Mr. Wu for his hard work in guiding his work and patient answers to the questions raised. Although future work may not directly engage in measurement work, these knowledge and experience foundations will serve my future career and strive to become an outstanding talent in civil engineering.

Part 2: Engineering Survey Internship Report

Foreword

At the end of the second semester of the 2008-2009 school year, from December 1, 2008, we conducted a 14-day engineering survey internship.

The content of this internship is the practice of engineering measurement knowledge. The requirement of the internship is to let each student achieve the basic mastery of the actual operation of engineering measurement. Compared with the previous classroom internships, this internship is more concentrated, more extensive, and more systematic. It is based on the actual control of measurement and production, and deepens the understanding, mastery and comprehensive application of book knowledge. It is to cultivate our theory and practice. , independent work ability, comprehensive analysis of problems and problem-solving skills, organizational management capabilities and other aspects of quality. It is also a concrete, vivid and comprehensive technical practice.

On the first day of the internship, Mr. Chang Yunyan gave us an internship mobilization. At the mobilization meeting, Mr. Chang emphasized the importance of this internship and analyzed the difficulties brought about by the internship due to the complicated geographical conditions of the hydropower school and the intensive construction. Students are encouraged to work hard to overcome difficulties and work hard to complete this internship. It also explains the precautions in the operation and relocation of the instrument, and requires that the internship supplies be kept during the internship. The instruments that need to be used in this internship mainly include level gauges, leveling scales, tripods, and theodolites. On the same day, we officially started the outdoor measurement work. Internship purpose

Consolidate the knowledge of classroom teaching, deepen the understanding of the basic theory of control surveying, can use the relevant theory to guide the practice of practice, achieve the unity of theory and practice, improve the ability to analyze and solve problems, and thus the basic content of control surveying Once applied, the knowledge learned will be further consolidated and deepened. Through internships, you will be familiar with and master the operating procedures and measurement methods for third and fourth control surveys. Master the basic skills of measuring measurement results with measurement adjustment theory.

By completing the exercise of controlling and measuring actual tasks, the ability to independently plan, organize, and manage surveying and mapping work is improved, and good quality and professional ethics are cultivated. Familiar with the working principle of level, theodolite and total station. Internship experience

The two-week engineering measurement study has ended. Through this internship, I have a deep understanding of the importance of linking theory with practice. The survey area is our Yongchuan District Water Conservancy and Electric Power Vocational and Technical College. Although the survey area is relatively large, it is basically the entire school. The mapping is also the plan of our entire school. In order to complete the task as soon as possible, our team works overtime on Saturday and Sunday. Taking measurements, we don't feel tired during the measurement process, and we don't feel hard, but we can enjoy ourselves.

Measurement is first and foremost a precise work. Through the study of measurement in the classroom during school, I have formed a basic, theoretical measurement profile in my mind. The purpose of the internship is to apply these theories. Linked to actual engineering. Metrology is the science of studying the shape and size of the earth and the location of the ground. In essence, the main task of metrology is to determine the position of the ground target in three dimensions and the change with time. In the information society, the role of metrology is increasingly important, and measurement results serve as the basis of the Earth's information system, providing the most basic spatial location information. The construction of information highways, basic geographic information systems, and various thematic and professional geographic information systems are all urgently required to establish a measurement database and measurement results information system with uniform standards and sharing. Therefore, measurement is the most reliable and accurate means of acquiring and updating basic geographic information. There are many types of surveying, such as general surveying, geodesy, photogrammetry, and engineering surveying. As a student of the Department of Architectural Engineering, we have to learn all aspects of measurement. The foundation of surveying and mapping is the basis of these expertise.

Through this internship, I learned the practical ability of measurement, and also had the patience to face difficulties; I also learned the unity and tacit understanding between the groups, and exercised my ability in many surveying and mapping. First of all, I am familiar with the use of level and theodolite, and have mastered various methods of using the level and theodolite, and mastered the inspection and calibration methods of the instrument. Secondly, in the process of checking and correcting the data, the sources of various measurement errors are understood. There are three main aspects: instrument error, observation error, and external influence error. Understand how to avoid measurement error and minimize the measurement error, that is, to select the appropriate instrument with higher precision in instrument selection. Improve your own measurement level and reduce the error level. The error is reduced by various mathematical methods of processing data such as temperature correction in distance measurement, correction of ruler length, and averaging over multiple measurements. Third, in addition to being familiar with the use of the instrument and understanding the source of the error and the reduction measures, we should also master a set of scientific measurement methods, and follow certain measurement principles in the measurement, such as: "from the whole to the local", "first After the control of the broken parts, "from high-level to low-level" work principles, and to achieve "step by step check." This not only prevents the accumulation of errors, but also finds errors in time, and can improve the efficiency of measurement. Through practice, I really learned a lot of real things, such as the operation of the measuring instrument, the leveling is more proficient, learned the digital terrain map drawing and the measurement of the broken parts, etc. Improve the ability to do hands and brains. In this internship, we also learned that in order to conduct good measurements, we must first master the basic theoretical knowledge. We must have a hard work spirit. Each team member must practice it personally, and the division of labor must be clear, and the work can be exchanged. To do it, we also need to know that failure is the mother of success. In the process of internship measurement, it is impossible to be completely free of mistakes. We should not be discouraged, continue to retest again and again, recalculate, practice again and again, and again and again. To improve measurement levels, we continue to learn from our experience. Thanks to the teacher's guidance, we encountered various difficulties at the beginning of our internship. Thanks to the patient's patience and explanation, we solved many problems in measurement.

During the internship process, we inevitably encountered some difficulties. At the beginning of our implementation, I was still worried that I would not test it. I couldn’t measure it. I was worried that I could only complete the task on time, only two weeks of measurement time. However, after repeated measurements by our team, our unity and tacit understanding overcame various problems in the measurement and finally completed the task on time. In the process of measuring the internship, we also encountered various difficulties.

Part 3: Engineering Survey Internship Report

One week of surveying and mapping practice has passed in the blink of an eye. I have gained a lot during this week. Our internship location is more professional in three art studios. This surveying and mapping internship feels ok when it first comes into contact. It is considered to be relatively simple. The length of the differential is not more than one meter. It takes less than ten minutes to open the entire reducer. The task assigned by the teacher is to draw two parts and one for each person. Zhang assembled the picture, I think that the drawing is good, I am confident that I can do it within two days, but the next days let me deeply realize that the way to be a mechanical machine is still a long way to go.

First of all, let me talk about the experience and feelings when drawing the parts map. I got the reducer, the drawing board and some measuring tools on Monday. In the morning, Mr. Sun explained the internal structure of the reducer and the names and functions of the various components. I realized that the content knowledge in the "Mechanical Drawing" that I learned in the last semester will be widely used in this internship. So after I returned to the dormitory, I sorted out the knowledge of the last semester, including how to mark and find data. The method, the part of the data in the parts drawing, the various parts categories and how to do the layout layout. After the teacher's explanation and knowledge, I was soberly aware that the basic purpose of the internship at this time was to combine the organic and practical measurement of the book "Mechanical Drawing" that I learned in my freshman year to achieve the purpose of learning. After clearing one point, in the afternoon I will classify the parts inside the reducer, classify the axes and gears, and then flip through the reference books that the teacher gave us. I will compare the actual drawings with the actual drawings and I should make measurements. What are the data, so do your heart. On the second day of the next day, the task I gave myself was to measure the data. It is the easiest to measure the parts in others' opinion, but I think the most important part is the measurement. If the measurement is not accurate enough, it will affect the subsequent data query including the deviation. , accuracy, measured grades, etc., will also affect the drawing of drawings. The part drawing I first painted is the middle axis. The main data is the diameter of the shaft. It is easier to measure but it is troublesome when querying the deviation. I don't know what kind of precision level and matching level, and reading is also a fog. In the end, there is no way to ask the teacher. I would like to thank my intern teacher Sun Jinrong for helping me solve the problem and help me correct the mistakes on the drawing. Through the guidance of the teacher, I successfully completed the drawing of the part drawing of the central axis. My second part drawing has the experience of the oblique tooth. The oblique tooth is easier to draw, but it is the calculation of the data and the trouble. Finishing, because the helical teeth have more data, so you need to draw a table. Although it is more troublesome, you can still find some roads after carefully reading the instructions. For example, the roughness and the axis connection are more accurate and the accuracy level is easy. I found the value and should be good at summing up during the whole drawing process, so I won't take more detours. Through the drawing of the part drawing, I realized that this internship is not only a large task but also a careful treatment of each data. Only a combination of theory and practice can find that the problem is mature.

After drawing the part drawing, the next step is to complete the assembly drawing. In the painting assembly, you have to have a good grasp of the whole, in order to select the drawing and the proportion, because the speed reducer of our group is not too big, so I choose 1 The ratio of 1:1. What to do before painting is the division of labor within the group. There must be a measurement group, a data processing group, and a mapping group. In the mapping group, the data group will process the good data for me, and then I will draw a little while. Every move requires data support. You can't paint on your own. The most important thing for people who are learning mechanics is to seek truth from facts and not be sloppy. For GB parts like screws, nuts and bearings, it is screened according to the selected national standard and listed in tabular form. After painting the assembly drawing, the feeling is a word tired, often repeating is an action is to look at the data line, look at the data line, but after the painting is more sense of accomplishment, thinking that each pen has its own efforts in it is very Enriched.

Originally thought to be a very simple internship, when you put it into it, it became complicated and interesting. It is easy to combine theory with practice, but there are too many things to pay attention to when operating. The theory is dead, but it is actually alive. The people who need to combine the two must have patience to study and encounter problems. It’s not true, it’s an attitude. This quality is essential for those who learn machinery, because what we do is a matter of millimeters. Although the mechanical surveying internship is only a short week, it gives me experience that will accompany my entire college career or even my whole life. This is the most important thing I have gained this week.
