Civil engineering survey experience

Part 1: Civil Engineering Survey Internship

Internship is a very strange word for me, because I have not experienced an internship in my student life for more than ten years. This is my first internship. He will comprehensively test my ability in all aspects: study, psychology, body, mind, etc. . Just like a touchstone, test whether I can use the theoretical knowledge I have learned in practice. It is related to whether I can successfully settle in this challenging society in the future.
Because of the short time, I was exposed to these things in those few weeks, but I am content.
If you don't practice a lot of problems, you don't think about it. After you practice, you know what you can encounter. This requires us to have rich practical experience. The practical experience of interns like the one who has just left the school is not very rich, but the theoretical stuff. If there is nothing, then it will not be able to eat during the internship. After a period of internship at the construction site, I realized that it was not the textbook middle school that couldn’t be used, but whether you would use it or not, and you couldn’t understand the changes and the opposites.
Internship content:
At the beginning, I went to the construction site to understand the construction drawings. I slowly walked and looked at it. I still couldn’t see any problems. I only saw the frame column and the foundation surface. The wood shed. The steel shed, etc.... After a few days, Master Li called me small. Li went with him to release the line. The line is the foundation of the building and is necessary for our beginners. During this period, I had a better understanding of the level and the theodolite, and I was more familiar with the operation of the measuring instrument. I also practiced the observation of the instrument on the construction site, which enabled me to adapt to operating the instrument under different conditions.
I am mainly responsible for the laying and marking of this site. Sometimes I help others to do earth measurement and measure the height. It is a skill that allows us to adapt to the field operation under more severe conditions. It is better to adapt to the worst environment. Let us learn more and be more solid. It is the most tiring thing in the earthwork site. It runs up and down with a level gauge every day. It also completes the measurement task. This is a challenge for the college students I just internship, and it is also a test that reflects my ability to adapt.
As we work with the measurement, we also need to do something else to enrich our internship life. Digging, digging stones, moving bricks... is the exercise of my will. Although I didn't have a good effect on these exercises, I also honed me at the same time, let me know the hard work, I have to adapt to the work life.
Two months have passed, and the two months of life have finally been fulfilled. I have done it too. The experience is also slowly experienced. I believe that there will be more exciting life in the future. I will work harder. .
Internship experience and gains:
The biggest gain of this internship is to learn to adapt to the environment. Through this internship, I adapted to this kind of site life. Although it is not necessary to go to work on the construction site in the future, but with this period of exercise, no matter what work is done in the future, there is a kind of perseverance that bears hardship and endurance, and also learns to adapt to the environment. In addition, I knew some problems on the construction site that were different from the school. I knew on the construction site how to be a technician and how to communicate with the workers.
Through this internship, I have gained a deeper understanding of the relevant knowledge of architecture. It should be said that learning more professional knowledge at school is only theoretical, and it is still somewhat different from reality. This internship has a certain amount of help for my ability to understand pictures. I know where to pay attention and carefully calculate when I map. Where the structure must consider the safety of the construction, and where to consider the actual construction problems when the line is released. It can meet the requirements of the specification and meet the requirements of the specification to achieve standardization of design and construction. Without this internship, perhaps only using the theoretical knowledge in books, not considering too many problems, it is even more impossible to think of whether the drawings I saw can be constructed. Although the construction site is bitter, what can be learned is some practical things. The exercise is the practical ability to solve problems.
After two months of internship, it is necessary to sum up. First of all, through this month's internship, through practice, I have learned a lot of practical knowledge. The so-called practice is the only criterion for testing the truth. Through personal experience, I have observed the construction process of the whole building at a close distance, and learned a lot of concrete construction knowledge that is very applicable. This knowledge is often my little contact in school, and I pay little attention to it. But it is a very basic knowledge.
University life is a day of intense and full of expectation. When you are studying leisurely, you always carry your bags, stay away from family, friends, and teachers, and go to the road of your own. However, when I finally can leave the nests of the elders like the eagle feathers that have just been feathered, and walk alone on the big stage of social work, I find that the road to life is so rough and bumpy, anyone’s success is It was a storm. In the short 60-day internship, I learned a lot of things that will help me a lot in my future work. This is the first time in my life that I have entered the society. I am going to work for the first time. I feel that life is really It's not easy.
The internship is essentially a simulation exercise before graduation. It is very important to be on the way to work in the society and to set foot on the job. I hope that life can be extended from this, and that what I have learned is really useful.

Chapter 2:

As a basic skill of the profession, civil engineering measurement is a skill that we must master in civil engineering students. At the end of the freshman year of study, under the organization of the college, we conducted a 10-day civil surveying engineering survey internship on campus.
“How is this internship more difficult than military training?” After a few days, we got used to getting up at 5 in the morning, and when we were measuring the life of measuring instruments, we no longer heard the previous complaints. In order to ensure the accuracy of the measurement and the time progress of the measurement, we always get up when the day is bright, bring the "guy" to the measurement site of the main one, the main two and the public junction! When the other professional students of the college go to the teaching building at 8:00 to practice the week, that is, when we finish work in the morning. When we returned to the dormitory in the morning, we couldn't take it easy. The original blank data sheet was waiting for us to calculate and verify. If the data meets the conditions well, if the angle closure outside the allowable range after the first day of our team's measurement is poor, we have to prepare to get up the next day and re-measure the work that was originally on the first day. After a short supplementary sleep in the afternoon, when other professional students were taking classes in the afternoon and preparing to enjoy a sumptuous dinner, we took the instrument again and measured again before the sun went down. In the evening of summer, whenever the sun goes down, when the sky is dark, it is already more than 7 o'clock in the evening. Putting back the instrument, it is no longer possible to have food in the school cafeteria. When I walk out of the school gate and come to the store, I look up and see it. It is a scene of class gathering. Everyone is gorging in the store. Originally thought that the evening can relax and rest, but this is not the case. We still need to summarize the whole day's work, and work out the next day's work plan to improve the efficiency of the team and ensure the completion of the progress. .
Practice can always find many problems, and it also exists in this measurement internship. First of all, I think that the biggest problem is that we use the instrument on the textbook. The knowledge about the instrument used in the textbook is relatively abstract. When it comes to real practice, we can't put the book knowledge into practice very well. The teacher gave instructions again. Second, we perform measurements efficiently while in the field. When we measured on the first day, the angle closure difference was actually more than three times the allowable value difference. The emergence of this problem shows that our ability still needs to be improved. We ignore the requirements of the alignment, do not try to focus on the midpoint, and seek convenience to directly focus on the Chinese flower rod, and we do not pay attention to the impact of weather on the measurement. The discovery of these problems also shows that our experience is still lacking. At the end of the drawing, we were very unfamiliar with the drawing of strange topographic maps, and did not apply some of the techniques in civil engineering drawings to the drawing of topographic maps. This also requires teachers to give us more guidance in the future teaching and promote our level of improvement.
Let me talk about this internship experience. Through this measurement internship, I think the biggest achievement is to combine the abstract knowledge of books with the measurement of reality. It is no longer that we simply read the text on the book, but it is really not very easy to understand the operation in the future practice. The use of measuring instruments and the development of in-situ measurement internships have made us more intuitively exposed to the discipline of civil engineering measurement. It has also laid a solid foundation for us to use instruments and control measurement and distribution better and faster after we have taken up our jobs in the future. basis. Let us also understand that the practical and practical characteristics of the civil engineering profession have triggered us to work harder to learn professional knowledge in the future, and to strengthen the combination of theory and practice, and to improve our professional level in essence.
In short, the 10-day civil engineering survey internship is very rewarding. Not only is my familiarity with professional learning and instrumentation, but also greatly promotes the rigor of my work and the cultivation of teamwork spirit. "The road is long and the road is long, I will go up and down." I will continue to work hard on the road of seeking knowledge in the future, and work hard to be a qualified civil engineer!

Chapter three:

Time flies, and the internship in just 20 days is over. In this short period of time, I have learned a lot and felt a lot, deeply feeling the importance of practice. This internship was completed at the Sanming City Transportation Planning and Design Institute. I mainly followed the technicians to conduct field measurements in the field and learned a lot of measurement knowledge.
I. Project Overview
The internship participated in the field survey of three projects, namely the Sanmingsha County Airport Entry Highway, the Provincial Highway Dongshi Line Qingliu Ninghuajie to the Ninghua Dongfeng Forest Farm, the Provincial Highway 205 Line Ninghua Jianning Junction to the Ninghua Dongfeng Forest Farm. The entrance road of Sanmingsha County is constructed according to the standard of new secondary roads. The design speed is 60 kilometers per hour, the total length of the road is 3.3 kilometers, the roadbed is 10 meters wide, the road width is 9 meters, and the water supply pipeline corridor is reserved. During the construction of the airport, the road was used as a construction machinery to enter and exit the road; after the airport was completed, the road served as a permanent road leading to the airport in Shaxian County. Provincial Highway Dongshi Line Qingliu Ninghuajie to Ninghua Dongfeng Forest Farm and Provincial Highway 205 line Ninghua Jianning junction to Ninghua Dongfeng Forest for a total of 60 kilometers, the whole line is built according to the standard of secondary roads, design speed 60 km / h The roadbed has a width of 10 meters and adopts a full-width cement concrete pavement structure.
Second, the measurement of the road centerline
The first contact with the total station is the field measurement of the entry road of Shaxian Airport, that is, the total station is used to measure the midline of the route. Since I had never been in contact with the total station at school, I didn't know how to use it when I saw it. The total station is composed of a full-station electronic theodolite and a microprocessor. It can automatically record, calculate and display related data such as horizontal distance, elevation difference, elevation and coordinates by measuring the vertical and horizontal angles of the slant range. The measurement of the total station is first and foremost a very precise job. Through the study of measurement in the classroom during school, I have formed a basic, theoretical measurement profile in my mind, and the purpose of the internship is To link these theories to actual engineering, this is one of the purposes of this internship. This section of the road is basically in the mountains, I have measured more than one kilometer of mileage when I came. We are divided into two groups of middle piles and transverse sections, and I am in the middle pile group. Since our work is in the mountains, we have to take the instrument into the mountains. I remember that it took nearly two hours to reach the working place from the mountain road that climbed for 30 minutes on the first day, and the lunch had to be settled in the mountains. This point makes me understand how difficult it is to build a road. It is totally uncomfortable to stay in the classroom. There is no danger in the mountains. There are dense forests here that can make you lose your way. There are many insects here, you will bite you and even cause allergies. There are quite a few valleys here, you may get lost. Go down. In the face of dangerous field work, I feel the importance of obeying the rules and regulations of the unit.
Measuring in the mountains requires more manpower than the plains. Because in the mountains, there is a need to smash instruments and water, but also to take a path in the mountains. The equipment to be equipped is: a total station, a tripod, two station handles with a hoe, a pole with a hoe, a test kit with data, and a hatchet. . The approximate process of the measurement is as follows: the pre-measuring instrument re-measures the rear view and then stakes out. If the next point is not detected, the turning point is required. The method of setting up the instrument: first set the tripod on the turning point, use the foot to put a corner frame on the foot, and install the total station on the tripod. When the center is right, the tripod is fully stepped on, and then leveled until Both the tube level and the circular level bubble are centered, and then the height of the measuring instrument is used, and then the coordinate of the instrument point and the height of the instrument are input, and the rear view can be measured after setting. Since the rear view is a lot of rear view in the mountainous area, it is necessary to use the station to improve the accuracy. Stand the tip of the middle pole on the nail head of the turning point, press and hold the telescopic button to fix the other two feet, release the button to lock the tripod, then press the telescopic button to adjust the height until the bubble is centered. Finally, Set the height and align the hoe to the total station. The running handle is the hardest work, and the runner needs to have a good sense of direction and distance. In the middle of the mountain, the runners often do not see the first few piles in the middle, so it is difficult to distinguish the direction. Usually 20 meters to play a pile, each element pile must be played. The runners first look at the route, take 20M, and point the hoe to the instrument to predict the position and distance. According to the measured value, it is determined how many meters to the left and right after the direction of the instrument. After the accurate value is measured, the runner will report the report to the recorder. The recorder needs to record the mileage of the mileage station and the coordinate elevation of the corresponding station. Need to prepare tools at any point, there are hammers, nails, plastic bags, wooden stakes, markers. The basic principle of the turning point is to stand at the turning point to see the instrument and see the route to be played next. The stake should be hit about 4 cm from the ground and it is not easy to be stepped on. Put a square plastic bag on the stake and punch in the nail. Finally, write a turn point on the square plastic bag, and then attach a red plastic bag to the top. In the mountains, the forest is too dense, which causes the total station to be inaccessible between the front and rear view and the running handle. This requires the worker to cut off the branches and trees that block the line of sight until the value can be measured. Writing the pile number and piling is relatively simple, and it is necessary to pay attention to the fact that the station number is written clearly and accurately. The way midline measurements work is basically the same.
Through a period of measurement work, I am familiar with the use of the total station, skilled in the use of the total station, mastered the instrument inspection and calibration methods. 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. Know how to avoid measurement data errors and minimize the measurement error. It is necessary to select a measuring instrument with high precision. Improve your measurement level. Multiple measurements were taken to average.
The difficult field work made me understand that in the field measurement work, you not only need to have a good measurement knowledge and skills, but also need a good body to cope with this hard work, but more need a spirit that is not afraid of persistence.
Third, the investigation of the old line
There are many contents in the geological survey, and the contents of the soil along the culvert and the shape of the rock mass are investigated. Walking on the old route, I saw a lot of things that I didn't pay attention to. The first thing that caught my eye was the road surface of the old line. Although the road surface was paved with asphalt, it was already devastated. It may be because the performance of the previous asphalt material is relatively poor. There are cracks on the road surface, which are horizontal, vertical and mesh. There are also ruts, strange pits, and on a short road I found that asphalt will stick to my sole. For me personally, of course, I like the current asphalt pavement. After all, it has good performance, such as: sufficient mechanical strength, certain elasticity and plastic deformation ability, no dust, and the car is more stable and low noise. Asphalt pavement is often used for highways and urban roads. The value of concrete pavement used for secondary roads is more expensive. I think with the development of science and technology, the pavement materials must be getting better and better, and driving will be safer.
The old road is indeed inaccurate in the shape of the road, and some obvious corners, so I saw the design of the new linear curve more gradual. There is a section of the up and down slope, the view at the top of the slope is very narrow, and the design of the longitudinal slope should be redesigned. There are not many vehicles on the road, so this is the reason why only two lanes are repaired. I don’t know much about the slopes of the old roads, only I realize that a rock slope is 90°. It seems that going back to supplement this knowledge.

Chapter 4:

At the end of the freshman study life, under the organization of the college, a two-week civil engineering survey internship was conducted at the two campuses of Yanshan and Pingfeng.
Measuring internships is much harder than we think, but after a few days, we are used to living early and late. I even liked it slowly. On the day before the internship, our team made a serious work plan and conceived the problems that we will encounter, in order to improve efficiency! However, when we arrived at the field, when we really started to operate, we discovered that the previous plan was just a piece of paper, and it seemed pale and weak in practice. On the first day of the internship, there was a rain that was dripping, when it was big and small. In the face of such bad weather, we did not back down, cheered each other, and gave support and encouragement. It can be said that in the morning, we have done a lot of work, but that is just that we are slowly exploring and looking for work skills. A process of training. After eating at noon, we discussed the afternoon work plan and produced a data sheet. After a short break, we went to the front line with confidence. The weather in the afternoon was better, but it was still drizzling. In accordance with the plan, I was so busy, and proceeded in an orderly manner. Although it was hard, when we saw a piece of white paper filled with data, it was very gratifying. The sky gradually darkened. It was seven o'clock in the evening. I returned to the campus after work. The school cafeteria was not eating anything. We came to the snack department next to the campus, ordered the pickled fish, and did not come up in the hot pot. Before, we had already prepared the rice well, and we were ready to show our talents. The dishes came, regardless of the personal image. Qian Qian had already been thrown into the clouds, and it was quite fragrant to eat it. I thought I could go back and have a good rest, but this is not the case. I have to calculate and check the data of the day. The problem occurred when the check was made, and the line of sight distance exceeded the limit. Everyone looked at each other and was very helpless. There was no way to prepare for getting up earlier the next day and re-measuring the work that was originally on the first day. Next, when the building is out of the internship, compared with the standard route measurement, it is relatively hard and easy. The main time is the operation of the theodolite, centering and leveling. Data processing before stakeout is important and directly affects the accuracy of stakeout.
Practice can always find many problems, and this internship also exists. At the same time, the importance of theoretical connection practice is also realized. I think the biggest problem is in the use of the instrument. The method of introduction introduced in the textbook is more abstract, and the teacher should be guided again during the internship. The measured line-of-sight difference on the first day is out of tolerance, indicating that there is still room for improvement in capacity. At the same time, we did not pay much attention to the impact of weather on the measurement, indicating that our experience is lacking.
In short, I have gained a lot in this measurement internship, not only the study of professional knowledge, the familiarity of the instrument, the ability to measure, but also the rigorous work of myself and the cultivation of teamwork spirit. In the face of difficulties, the patience and perseverance that comes out. "The road is long and it’s a long way to go. I will go up and down." In the future, I will continue to work hard on the road of seeking knowledge, not arrogant, and strive to be a qualified civil servant!

Chapter 5:

After two weeks of measurement internship and post-measurement data processing, the internship ended smoothly. In this short two weeks, we encountered a lot of difficulties in the measurement process, we also overcome a lot of difficulties and solved some problems that have been plagued for a long time. These two weeks are intense and full two weeks. Here are my internships.
Civil engineering measurement is a more practical work. Through this measurement I found out that I am a civil engineering student. Measurement is also a pragmatic and realistic job. It is not a sloppy one. We must maintain the originality of the data in the measurement internship. This is also very important. In order to ensure that the correctness of the calculation is valid, we have to check whether the data of each measurement point is correct. We inevitably make some mistakes in the measurement, such as the reading is not accurate enough, the reading of the leveling rod or the flower rod is not vertical, the reading interval is too long, etc., will cause some errors, so we are The internal calculation in the measurement should be carried out simultaneously with the measurement, so that errors can be found in time, errors can be corrected in time, and many unnecessary troubles can be avoided, saving time and improving work efficiency. Since this is a historical work, a lot of data may be used in the future. We must try to plant the validity of each data. Keeping the original data is also beneficial for future verification. This also reflects the spirit of pragmatism and truth. In this experiment, we should do this in our future work and life.
This internship is also an opportunity to cultivate our independent thinking and work ability. In the measurement process, we have to think about how to set points, how to measure, which data to measure, and how to ensure the measurement. The validity of the data is then discussed together. We don't have a lot of experience, and we don't have the genius of surveying and mapping. This is to inspire our individual subjective initiative, to exert our personal ingenuity, and to give ourselves a chance to play.
In this measurement internship, due to personal factors, this measurement has brought a lot of troubles, such as not serious, not concentrating on copying data errors, which leads to problems in calculation; and calculation errors will also give future surveying work. It brings a lot of inconveniences. These mistakes that should not occur are caused by the individual's unsatisfactory and unfocused attitude. It is necessary to correct the work attitude and do a good job in every job in the future work. . In the work, we must maintain a calm and calm state, so that we can make fewer mistakes to improve work efficiency. This is also a condition for cultivating individual independent thinking. As long as we maintain this state, we believe that many problems can be solved.
The two-week survey internship is not long or short. It takes a certain amount of effort to successfully complete the task. After all, we are “newborn calves” and always have a certain curiosity. However, in this internship, we also fully exerted the personal initiative and the spirit of cooperation of the group, and completed the task that the teacher gave us. Although there are still many deficiencies, what we know and learn is only civil engineering measurement. In the tip of the iceberg, but we will not be proud, we must continue to work hard in the future work and study.
This measurement internship fostered the feelings of our classmates. Measurement is not a person's measurement, but everyone's measurement. It is not enough to rely on one's strength and thinking. The measurement in group is the true measurement. The team's unity and cooperation enabled the measurement mission to be completed smoothly. Everyone faced with the cold weather and still worked with an umbrella to form a team-friendly partner. You take an umbrella to measure, and slowly realize that you can unite to complete the task. Everyday work tasks are carried out after consultation and distribution. When we measured the horizontal angle yesterday, we measured the elevation or distance. This will give the process a certain guarantee.
From the drawing, the analysis of the data and the completion of the graphics, a lot of knowledge emerges in the brain, and the formulas of those calculations are more understandable. From that, I found a lot of problems, the calculation of errors, the processing of data, and the ability to cultivate our drawing, what is called a topographic map, and how it was drawn. There are always problems, but after thinking and pointing out, the students will solve it. This internship gave me a big test, I have a great understanding of the measurement and gained a lot.
In general, I hope that after the civil engineering survey internship, I will stick to it. The combination of theory and practice is the biggest gain. Let me know a deeper step in the civil engineering profession. Although it is not a real work measurement, I have an internship opportunity for future work. The two-week survey internship ended, and I learned from it that the knowledge learned in the real world is much stronger than sitting in the classroom.
