2014 measurement internship summary

Survey internship summary

The one-month, stressful and unforgettable measurement internship life is over. I will start normal classes next week. I just didn’t like it when I was internship, but after I experienced so much, I felt really fulfilling. Significant.

Practice is the sole criterion for testing truth.

Through this internship, we will consolidate, expand and deepen the theoretical knowledge we have learned from the classroom. First of all, I have mastered the knowledge of measurement in the classroom and know how to correctly use the level, theodolite, total station to measure the distance, angle, The height difference, etc., as well as the method of drawing the construction stakeout and topographic map. Since it is to be measured, it is inseparable from practice. Practice is the best test of the knowledge of surveying. I only have a lot of specific knowledge in the classroom, especially the use of the instrument is a mess. When I started measuring on the first day, my heart was still worried: how to carry on the task. When you start, it is not difficult to find out. Listen to others or read the textbook, and then do it yourself. In order to improve efficiency and measurement accuracy, you should practice frequently so that you can do the opposite. This knowledge is very important and very basic knowledge. As a result, I have accumulated a lot of experience and I have learned a lot of practical knowledge.

Unity is power, and discipline is the guarantee.

Once a measurement internship is completed, it is not enough to rely solely on the strength and concept of a person. Only the cooperation and solidarity of the group can make the internship complete quickly and efficiently. This measurement internship has fostered the ability of our team to work together and enhance the relationship between classmates. The principle of completing this internship is to let each team member learn the knowledge and actually operate, instead of grabbing the time, rushing to the progress, and rushing to work. Therefore, each of our team members independently observes, records each station, and accurately calculates. Doing "step check" in step by step can not only prevent the accumulation of errors, but also find errors in time, and improve the efficiency of measurement. With a rigorous attitude, we will rework when we are wrong, and we will never be sloppy. Until the measurement requirements are met. We know that what we need to do in engineering is to be careful and rigorous.

After the unity of each team member, we completed the work of the side chart, and everyone was excited to see the drawings we had drawn. In the experience of our group of students in the exchange measurement, everyone feels that there are many gains. Some say that the exhibition point of the instrument is very important to the size of the error. Some say that the midpoint of the level measurement cannot be set too far, and so on. Think about getting up to the instrument at 7:00 every morning to measure, and to calculate and modify the error, and re-measure. With the power of unity, we are still very energetic. I also learned from others that things that were not too clear before, such as the processing of data, the observation of horizontal angles, and some of the questions of drawing were answered in the measurement.

Measuring internships, I have learned a lot of real things, have a comprehensive application of the measurement knowledge of the previous piecemeal, and have a good understanding of the control measurement and topographic mapping process. I learned the things that can't be done in the classroom, such as the drawing of topographic maps, and the more skilled use of measuring instruments and tools such as levelers and theodolites. It has well consolidated the theoretical teaching knowledge, improved the practical operation ability, and also expanded the ability of communication and cooperation with classmates. Of course, there are many teachers and teachers who help. When each of our groups basically draws a good picture, the teacher's inspection of each group will cause us to correct it in time. In fact, think about the measurements on the campus every day, we are also a good scenery. I still remember that at 7 o'clock in the evening, we had to re-measure because of a site error. We were busy for a long time and we didn't even have time to eat dinner. In short, in two weeks we also experienced a lot of ups and downs, some measurements are smooth and even zero error, sometimes the measurement hits the wall everywhere, but it is also past, and the measurement is still very happy. Although everyone in the measurement is lazy, I don't want to test it.

I cherish the important part of the school's connection between the theory and the reality of the internship. Thank you for the internship arranged by the school to promote students' practical ability. At the same time, I would like to thank the teachers for their careful and patient guidance. We must have such achievements first. Thank you, our instructor, I will always cherish this experience. At the same time, this internship life is also the most memorable in my life.

Survey internship summary

This is the first internship since I entered the university in the past two weeks. This internship is a measurement teaching internship in civil engineering. One day before the internship, the teacher arranged the task. I was a little overwhelmed and didn't know how to complete the task. It turned out that it was not that simple.

On the first day, we realized that the internship was not so easy. We don't know how to start our mission, not what we should do tomorrow, what to do tomorrow, there is no good plan for the internship. The division of the six members of the team is also unclear, which has led to inefficiency in doing things. A series of questions came to us at once, and I felt that this was a powerful challenge for me. On the first day, although we were inefficient, we started working together from 6 am to 7 pm. We spent a lot of time to familiarize ourselves with the internship. Everyone was very tired when they finished work that day. When we were eating together, we summed up the problems that occurred during the internship on this day and determined the specific division of labor for each person in the future. At the same time, we also plan together what we have to do every day. In this way, we are more efficient and purposeful in our work. Sure enough, we did a lot better the next day than the first day.

This measurement internship is really hard work. Every day, I keep looking for broken points, fixing points, finding points, reading, counting, drawing, and fixing work every day is sometimes very tired. Also worry about whether our operation is correct. If there is a little error, then the data will be scrapped and reworked. It is very troublesome. We also encountered a lot of problems in the process of measurement. Every time we encounter a difficult problem, our group will always have a heated discussion. In the end, if you can't reach a conclusion, ask other classmates or ask the teacher. I sometimes feel that we are really lucky and happy because we have a very kind and kind teacher. The teacher is accompanying us at the measurement site every day, whether it is the big sun or the heavy rain. And the smile on the face of the teacher every time she sees her is always very kind.

Although the internship was only a short two weeks, I did not only have a deeper understanding and understanding of the textbook knowledge through this internship. I also learned from this internship what is the importance of teamwork and the power of unity. . Have fun to share, have difficulties to work together, we have a very united and excellent team, we are happy and hard to forget to do things together. I feel honored and proud to be one of such excellent teams! This internship experience will surely become a good memory in my life.

Survey internship summary

The unified deployment arrangement of the School of Architecture and Engineering of Xinjiang University, Deng Wenbin and Gao Changnian as the instructors, the two-week internship control measurement internship has ended. Our professional students in the surveying and mapping project learned a lot from this internship and experienced the hardships of being a surveyor. The pre-school stage is based on theoretical study, and the understanding of the surveying and mapping profession is not very comprehensive. We have been serious and serious throughout the internship because we know that metrology is a very practical subject, and topographical internship plays an important role in developing students' thinking and hands-on ability, mastering specific work programs and content. The role is also of great significance to the future of the job to achieve their own life value.

First, the purpose and requirements

The purpose and requirements of this internship are to master the use of commonly used measuring instruments, to master the layout of the wire control network and the observation and calculation methods of the third leveling. After the instrument was distributed, we conducted an internship on a group basis. Leveling is performed first. In the school, the level of the cadastral manhole cover is selected as the starting point, and a closed level route is arranged around the school. The level is selected on the roadside, and the points are determined and marked and numbered. The fourth-level leveling method uses the medium-wire reading method. The order of observation for each station is: post-front-front-back, and the number of stations to be observed is even.

Second, the use of level

1: Placement instrument 2: Rough flattening 3: Aiming level 4: Accurate leveling 5: Reading

I have already practiced the use of the ds3 level in my daily study. The level used here is the automatic level, which is more advanced than the previous ones. The readings are omitted. The smooth completion of each of our observations has greatly improved our measurement speed. The first thing we did in this internship was to go from the benchmark point to the level of the known level. We encountered many problems during this first off-campus internship. For example, out of the school, we mainly set up on the sidewalk. The passing pedestrians directly affected the normal measurement of our measurements. Now it is summer, hot weather, glare of the sun, not only affecting the readings of the instruments but also testing our classmates. The endurance of the door. But in the process of measuring, we maintain a calm mind to find the right opportunity to accept the test of the sun with a strong will. When testing the measured data, it is found that the error is immediately solved and the rework is performed immediately when the reading result exceeds the limit. At the same time, it is also found that the measurement work generally reflects the measurement, calculation process and result on the specified record form. There is a calculation check, ∑a ∑b=∑h, which only indicates that the calculation is correct, but it does not reflect the merits of the measurement results. After the field measurement is completed, the calculation of the difference difference closure is performed. Within the allowable range of the tolerance, that is, the length of the standard route or the number of stations is adjusted. If the tolerance is exceeded, it must be re-tested until it is qualified. After the leveling was completed, we received a new instrument: the j2 theodolite, ready for wire measurement. Three known coordinate points are selected as control points in the school, and the control points are arranged outside the school to connect the control points, and all the control points are connected into a closed and a wire, and each control point is nailed with steel nails and numbered.

Third, the use of theodolite

The horizontal angular measurement in the traverse measurement is very demanding for us, we use the j2 theodolite. Since we have not touched the j2 theodolite in our daily study, Gao Changnian gave us a detailed explanation, which made us understand the difference between j2 and j6, and j2 each station measured data 3 8 13 9 Limit requirements. The accuracy of the j2 theodolite is very high, which requires us to always be rigorous in doing things, not to be sloppy for every detail. At each station, it is necessary to check whether the data such as the screw-in and out-out readings, 2c, etc. are over-limit, and if the over-limit is immediately re-tested, it will go to the next station until the tolerance is met. In order to avoid large errors in the internship, we also summed up a lot of experience. For example, we use the method of taking the average of the face 1 and face 2 to eliminate the eccentricity error of the sighting, the axis of the sight is not perpendicular to the horizontal axis and the horizontal axis. Residual error that is not perpendicular to the vertical axis. For example, when observing the angle of the endpoint on the short side, pay special attention to the alignment. When aiming at the target, try to aim at the bottom of the target, because their influence on the angle measurement is proportional to the distance. In order to eliminate the scoring error of the dial, it is necessary to configure the position of the dial, and configure each roundback. The main problems we encountered during angle measurement were the effects of instrument sinking and roadside pedestrians. Because the candidate points are far away when the wires are made, and they are all along the road, the pedestrians in the passing vehicles are very disturbed, especially the control point of the corner of Nanchang North Road to Beiyuanchun. It is next to the North Park Spring Crossing. Facing the endless stream of vehicles, wanting to aim at the point is the ability to take great patience and seize any opportunity. In order to avoid the interference of pedestrians and vehicles, our door is going out early every day, we must hurry up when there are few people; and at the corner of Altay Road to Nanchang Road, due to the influence of terrain and features, the surveyors do not observe Clearly measured, after the discussion of the whole group, two solutions were proposed: a. use a long benchmark instead of a short test; b. use a plumb line instead of a test. After considering all the factors, after trying, we successfully measured the station with the benchmark. In the process of angle measurement, let us all see the importance of rigorous work in the work, and let us grow up in practical problems. After the internship measurement of this project, we also deeply realized that the power of unity is great.
