Surveying internship summary

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. Measurement results, as the basis of the Earth's information system, provide 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 training, I learned that it is not enough to rely on the strength and concept of a person to complete a measurement internship. It is impossible to do the work to be done. Only the cooperation and solidarity of all the members of the group can make the internship complete quickly and efficiently. The so-called "three smugglers, the top of Zhuge Liang", only if we unite, what difficulties are no longer difficult. In addition, this measurement internship also cultivated the ability of our team to work together, enhanced the feelings between the students, deepened the friendship, and connected some of the original "strangers" closer. Of course, in the internship process, it will inevitably encounter some embarrassing things, making everyone unhappy, each has its own methods and insights, but we can communicate and communicate in a timely manner, the wrong party is not so stubborn, the right party Not so obvious, I forgot the unpleasantness of yesterday, and greeted the new sunrise! Of course, I believe that the other purpose of the school to let us train is to let each of our students have a deeper understanding of how to use the total station and level. And it is possible to complete a job alone, and then rotate after the corresponding exercise effect to achieve the purpose of joint development, instead of simply grabbing the time, rushing to the progress, and rushing to work, at this point our group is doing very well. Seriously, each team member conducts independent observations and records each station. The total station measurement is performed on the spot, and the problem is solved in time. There is no check on the previous step, and the next measurement is never taken. To check the steps step by step, and to calculate the internal industry accurately after returning, because this will not only prevent the accumulation of errors, Finding errors in time can improve the efficiency of measurement and avoid inaccurate measurement and retest. Even if we retest, we will rework with the rigorous attitude and will not be sloppy. We know that we are working

In this line of work, what is needed is careful, patience, perseverance and rigorous attitude. So we have been overcoming the shortcomings of the past, step by step and want to move forward!

From this internship, I summed up a few points to avoid large errors, such as:

The ruler should be straight, try to avoid shaking. When there is shaking, you should select the minimum data, and then adjust the bubble of the field of view before entering, otherwise the error will be very large.

When reading data, each member must be careful, both accurate and decisive, and cannot hesitate. Any mistake can lead to the retirement of the final result.

The selection point is very important. The point must be selected in a representative place. At the same time, it should be noted that not the more points, the better. On the contrary, the excessive useless points will not only increase the labor and time required for measurement, calculation and drawing, but also Because of the many points, the clutter produces a large error.

Unity is strength, discipline is to ensure the unity of work through each team member. When we learn from the experience of our group of students in exchange measurement, everyone feels that there are many gains. Some say that the exhibition point of the instrument is very important, because it is related to the error. Size, some say that the measurement midpoint can not be set too far, the level measurement process must be used and the precise alignment and leveling of the bubbles during the instrument process, and we must have a heart care instrument, the instrument used Be careful, in school, and even more so when you are on the job, so you can avoid unnecessary troubles and so on.

Through practical measurement internships, I learned a lot of real things, such as the more proficient operation of experimental instruments, and learned the things that can't be done in the classroom, such as the drawing of topographic maps and the measurement of broken parts. Improve the ability to do hands and brains, but also expand the ability to communicate and cooperate with classmates. 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. From this ten-day measurement, it is more important to understand the important life of several things: First, the cooperation between people is very important. If they cooperate with each other, they will collapse like a sand. Especially in conjunction with such an important measurement science; Second, the unforgettable three-week measurement internship is finally over. I have learned a lot and learned a lot.

I basically mastered the knowledge of measurement in the classroom, know how to correctly use the level, total station to measure distance, angle, height difference, etc., and learned how to draw the construction and topographic map. Metrology is the science of studying the shape and size of the Earth and determining the location of the Earth. 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

When I started measuring on the first day, my heart was still bursting with my hair: 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.

I know that everything must be done carefully and carefully. There must be no sloppy sloppyness, especially when using precision instruments such as level gauges and theodolites. Because a slight error can lead to a large deviation of the data, it will lead to other measurement errors in the future, and eventually lead to errors in data calculation. For example, when we first start measuring the angle, a reference point is not aimed, resulting in a small angle. Then the angle closure difference does not meet the requirements. After verification, it is found where the problem lies.

Surveying internship summary

The one-week surveying internship life is over, but in this short period of time I have learned a lot and I feel deeply.

This internship not only gives us the opportunity to apply the knowledge of this semester, but also teaches us what is true teamwork.

From the initial internship mobilization to the final total station measurement, a week of hard work, in exchange for a filled high-precision form, standard drawings, which gave me a small sense of accomplishment. We remember the internship content that the teacher said. We must unite and help each other, work together, be rigorous and realistic, care for the instruments, and do not speak loudly and meticulously carry out our measurements.

Perhaps a trace of excitement may be a little bit rusty, the first day of measurement is slower than the other groups. In time, it was analyzed because the speed of the centering was too slow, so we carefully studied it. After several measurements, we finally found some suitable methods, which can be quickly and accurately aligned.

In the process of centering the theodolite, I have summarized the following points to ensure that the instrument can be centered quickly and accurately:

1. First adjust the tripod to the appropriate height before unfolding and ensure that the three legs are of equal length;

2. After fixing the instrument on the tripod, first adjust the foot screw to the approximate level, and then ensure that the tripod is horizontal in the approximate centering position;

3. Finally, fine-tune, while observing through the eyepiece of the centering device, centering, then leveling, and repeating 1-2 times.

After summarizing the experience of the first day, the subsequent measurements went very smoothly. Everyone worked in a division of labor to form two small units, and at the same time, the angular distance and elevation measurement were carried out, which greatly improved the work efficiency. Subsequent fragmentation measurements deepen the ability to collaborate between our teams. In the process of measuring the broken parts, we take turns to carry out the process, the centering of the instrument is leveled, the readings, and the drawing are made to ensure that everyone has a clear understanding of each process and can master it skillfully. As with the first day, it is divided into two small teams, three for each team, one with the theodolite, and the other with the tape measure. After a period of time, they are exchanged. At the same time, the points are drawn on the sketch, and the students of the drawing are displayed on the plan. . When the three main points were staked out, in order to reduce the error, even shouting a left/right shift of one millimeter fully reflected the spirit of our excellence. On the last day of total station measurement, I wanted to use the data of our group, because our accuracy is the highest, there is 1/5448.9. But unfortunately, the data sheet unfortunately fell in the dormitory, it is useless, it is really regrettable.

Through this internship, I deeply realized the importance of measuring the hard work and the precise and careful group required for cooperation. During the period, I consolidated the placement of the level gauge, the method of aiming and reading, and firmly grasped the observation steps and record calculation of the closed level measurement: reviewing and mastering the use of the compass instrument; deeply understanding the basic structure of the theodolite, and being able to expertly Medium leveling and horizontal angle observation; proficient in the layout of wire points and field calculations; preliminary grasp of the method of garden engineering stakeout, and the importance of measurement and the rigor of requirements during production practice. Six people in the same group worked together to make great efforts under the cold wind of the hustle and bustle. The division of labor was clear. The use of instruments and vertical rods in turn took the group's ability to cooperate and deepened the understanding between each other. Cold weather can't resist our perseverance, and complicated measurements are more than our patience. The knowledge and teamwork I learned in this survey will be of great help to my future study and life, and I am very happy to have completed the task well.

Surveying internship summary

Through this internship, I mastered the basic operation of the total station, and learned a lot of methods of measurement. I got the initial experience and basic skills of measuring the actual work, and focused on cultivating our independent work ability, and further proficient in measuring instruments. Operating skills, improve the speed and accuracy of measurement, and have a comprehensive and systematic understanding of the whole process of mapping large-scale topographic maps in small areas. This knowledge is often rarely touched and noticed in the classroom, but it is Very important and very basic knowledge. As a result, I have accumulated a lot of experience, so that I have learned a lot of practical knowledge. A measurement internship should be completed completely. 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 complete the task. 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.

E.g:

When setting up the ruler, the ruler must be selected in an important place. Therefore, the selection point is very important. The point must be selected in a representative place. At the same time, it should be noted that not the more points, the better. On the contrary, the excessive useless points will not only increase the measurement, the labor of calculation, but also take time. Moreover, there will be a large error due to the confusion of many points.

In the test and measurement, the road and the main building should be determined first, and then the eccentric method should be used to measure the tree, the electric pole and the like. This is not only clear, but also conducive to the accuracy of the drawing and the comparison between the physical object and the graphic at any time. Thereby verifying the accuracy of the measured data.

After the teamwork of each team member, we completed the work of the side total station measurement. Everyone was excited to see the sketches we had drawn. When we learn from our group's students' exchange measurement experience, everyone feels that there are many gains. Some say that the alignment of the instrument is very important to the size of the error. Some say that the instrument is very important, and so on. Think about getting up to the instrument every day at 8 o'clock in the morning to measure, and calculate and correct 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 cross-section measurements, eccentricity measurements, and some of the questions that were drawn were answered in the measurements.

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 use of the total station. I learned some things that I couldn't do in class and more skilled use of measuring instruments and tools like total stations. 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 is measuring data, each of the teachers' inspections will cause us to correct them in time. In fact, think about the measurements we take on campus every day, we are also a good scenery. I still remember our first internship. We had to re-measure because of a site error. We were busy for a long time and didn't even have time to eat at lunch. In short, in two weeks we also experienced a lot of ups and downs, some measurements are smooth and even zero error, and sometimes the measurement is hitting the wall, but it is over. I am very happy to have completed the measurement. Although everyone is lazy when measuring, I don't want to test it, but it is quite good.

But the two-week internship also gave us a lot of lessons: because of the misreading, mistaking, and miscalculation of a certain data, it has brought us a lot of trouble, so that we know that we must be serious about doing anything. The unity of a group is also crucial, and it is related to the progress of the entire group. Previously, our team did not have a tacit understanding, and the division of labor was not reasonable enough. The overall progress was greatly affected. Later, through the exchanges within the group, the above problems were completely solved. The progress of the internship has been greatly improved, and the progress and effect are naturally brought up.

I cherish the important link between the theory and the reality of the school arrangement for us. I have a deeper understanding of the close relationship between theory and practice. I understand that some things are not available in textbooks, and some problems are in practice. Solved in. In short, I would like to thank the school for the internship arranged to promote students' practical ability. I will always cherish this experience. At the same time, this internship life is also the most memorable in my life.
