Engineering Survey Internship Report

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. The tasks of each week are arranged on the Friday or weekend of the previous week, and the information is checked on the weekends, so that each of our students can better enrich their theoretical knowledge and check the problems in 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.
