1.3 Internship location

This internship location is located in Qiaotou Town, Sheqi, Nanyang, Henan. Qiaotou Town is an important town in the western part of Sheqi County, located at the junction of Sheqi, Wancheng and Fangcheng counties. It has jurisdiction over 16 administrative villages, 103 natural villages, 232 villager groups, 43,500 people, 83,800 acres of cultivated land, and the Nanzhu Highway passes through it. The main canal of Yahe River runs across the whole country, with convenient transportation, sufficient water resources and rich products. It is a high-quality cotton producing area in my country.

1.4 Project Introduction

This internship project is the 1:2000 topographic map surveying task of Sheqi Qiaotou Town undertaken by Nanyang Surveying and Mapping Company. The actual measured area was about 20 square kilometers. More than 10 people used the total station automatic tracking measurement mode, and the measurement was completed within 20 days.

1.5 Internship Arrangement

I arrived at the internship company on March 1, 20XX. When I arrived, the control points in the survey area had been laid out, and the survey area was nearly 1/3. I participated in completing the remaining mapping tasks in the internship company.

2. Internship process

2.1 Preface to the internship

With the rapid development of social economy in recent years, digital mapping has its high mapping accuracy and data The collection is fast, the use and maintenance of the product are convenient and fast, and the utilization rate is high. It is widely used in surveying and mapping production, land management, urban planning and other departments, and is accepted by the majority of users. It can more easily transmit, process, and share digital information. By controlling graphics layer data, it can output the special information required by users, that is, digital terrain maps, which has a positive impact on the development of geographical information in the information age.

2.2 Operation Principle

The main operation process of digital mapping is divided into three steps: data collection, data processing and data output of topographic maps (printing drawings, providing data CDs, etc.) .

The digital operation flow chart is as follows:

The method used for mapping in this internship is ground digital mapping, using a total station for field digital collection, and on an in-house computer Southern software was used for data processing and graphing.

2.3 Surveying and mapping software

In this operation, Southern CASS5.0 software was used for in-house processing. Southern CASS5.0 is developed based on the AUTOCAD platform. All functions of AUTOCAD can be used. AUTOCAD is the most recognized drawing platform in the world. Its editing functions are obvious to all. Three operating methods are provided: electronic tablet method, original drawing digitization method, and internal and external industry integration. On the basis of CAD, many functions have been developed, such as measuring fixed points, copying graphics, drawing multi-functional composite lines, etc. In addition, it also provides functions such as cadastral table drawing and drawing management.

2.4 Operation process

2.4.1 Introduction to operation

Field digital mapping is the digital mapping method most commonly used by various surveying and mapping units in my country. Station instrument automatic tracking measurement mode, the measuring station is equipped with an automatic tracking total station, and Japanese Topcon measuring instruments are selected.

2.4.2 Operation process

We also use field sketches + indoor interactive editing to complete the surveying work.

During our surveying and mapping process, the Communist Party of China is divided into three topographic surveying and mapping groups, with each group having 3 to 4 people. One person observes, records and codes on the total station, and two people run rulers and draw in-house.

In the point coding method, we code one measuring area one by one. Based on the location of the control points and the actual daily workload, a manual sketch was drawn on site and marked on the sketch. Point numbers were exchanged with the measuring station every 10 points to prevent errors. After completing the numbering (coding) of each point in the field, when you return indoors, you can display the points transmitted to the computer in the form of drawing and coding on the computer screen. Coding with these point numbers makes it easier to connect these points. Or you can realize automatic connection by compiling coding guide files. After completing this work, these maps will be taken to the field for comparison, various data not measured in the field will be measured, and then interactive editing will be performed on the computer to obtain the final topographic map.

2.4.3 Precautions

2.4.3.1 Key points of the ruler

Using the above method, the requirements for the observation and ruler personnel are relatively high. The first step is to have a tacit understanding of cooperation. After this point is tested, the next point to be tested should be a telepathic connection; the observer is required to have a high level of proficiency in inputting numbers and letters, which should generally be completed within 10 seconds. The second ruler is responsible for the indoor drawing work and is the main person in the mapping process. Therefore, he must be aware of the comprehensive selection of land features (landscapes), etc., and he should determine the route of the ruler before running the ruler, and try to Avoid taking the wrong path.

Using this measurement method is trouble-free and quick. All that is required at the measuring station are coding and sighting, while the ruler staff only need to report the coding through the walkie-talkie and place the prism. Today's total stations measure a coordinate basically within 1 second, and some even measure a point in 0.3 seconds. Affected by factors such as walking, it takes about 30 seconds to measure a point on the ground and less than 1 minute on the landform. It can be said that the main time is the time from one point to another. In such a short time, it is difficult to draw a sketch. Basically, personnel cannot keep up with this idea and speed. After I measure the hour meter every day, I can measure about 600 to 900 points every day. Moreover, the connection success rate is above 95%.

　2.4.3.2 Key points of fragments

In the process of measurement, the selection and measurement of fragment points are very important. Too many measuring points will lead to a dense map and should not be It's important; there are too few measuring points and the basic elements of the terrain are not grasped. Therefore, when determining the fragment points, pay attention to the following points.

1. If the building is relatively square, you only need to measure three points. The fourth point can be completed by a computer. Many buildings in the south look square, but they are actually irregular polygons, so all the buildings need to be measured. Actual measurement point.

2. Irregular landforms should be measured as many points as possible, because in traditional surveying some small changes can be done manually, but computer simulations cannot reflect these realities more realistically. Topographical.

3. For the blocks drawn in the order specified in the program, such as bridges, billboards, etc., it is best to measure them in that order.

2.4.3.2 Other matters

1. All instruments and equipment to be used must be appraised by a qualified appraisal department.

2. The division of mapping units should be based on natural boundaries as much as possible, such as rivers, roads, etc., to facilitate the surveying of topographic maps and reduce edge problems.

3. Try to measure the points that can be measured, and try to avoid using steel rulers. Because the speed measured with a total station is far beyond what can be measured with a tape measure, and the accuracy will be higher

4. When collecting field data, cooperation must be tacit and not within the visible range of the measuring station. By using walkie-talkies to transmit information, the person running the prism must promptly report the terrain and feature data point information they want to collect to the station personnel to ensure the authenticity of the data records.

5. Since a lot of digital surveying work is done on computers, how to strengthen inspection is a matter for each unit to solve. Especially when the measurement area is far away from internal business locations, certain measures must be taken.

6. Try to collect data in the visual atmosphere of the measuring station. In places with poor visibility or when observation needs to be done by raising poles, lead the point to a nearby station to collect data. Avoid human errors caused by poles deviating from terrain and feature points.

7. When collecting data in the field, be sure to pay attention to the changes in the ground features and landforms on the ground, record them in as much detail as possible, and do not bring doubtful points back to the office for processing.

3. Internship experience

Graduation internship is a big exercise that is about to leave the campus and enter the society. It integrates what has been learned in the majors in the university for four years and is a comprehensive application of knowledge. I gained a lot during my short time at Nanyang 3D Surveying and Mapping Co., Ltd.

First of all, through the graduation survey internship, I learned a lot, such as becoming more proficient in operating instruments, strengthening my understanding and mastery of the learned knowledge, and improving my hands-on and brain-using abilities to a great extent. After reading the book, I finally realized that it was shallow, and I knew that I had to practice this matter.

In the internship, you are faced with real tasks, and there is no room for shirking or escaping. Field work does not give you time to go back and read books. Everything must be solved on the spot. Therefore, this made me deeply understand the importance of theoretical knowledge. During the remaining time in school, I must sort out and review the theoretical knowledge I have learned with peace of mind, so that there are gaps in my mind and it is clear at a glance. Lay a solid foundation for future practical work.

Secondly, it expands the ability to communicate and cooperate with others. I deeply feel that for the successful completion of a measurement work, it is far from enough to rely on the strength and ideas of one person. Only the cooperation and unity of the group can be fast and efficient. Therefore, in future work, while constantly strengthening my business capabilities, I must learn to live in harmony with my peers, learn to be tolerant, and learn to endure.

Once again, through internship, I also realized the importance of asking for advice humbly. At work, some of my colleagues only have technical secondary school or middle school education. They have not received higher education. They are often lacking in theoretical knowledge, but their rich experience is a valuable asset. This kind of wealth is learned in textbooks. less than. Therefore, in future work, we need to learn from the surveying and mapping staff who work on the front line all year round, and we must not put on airs or show off our temper. Ask for advice humbly, study hard, and adhere to the combination of theory and practice to become a qualified engineering personnel faster.

2000 words summary of engineering surveying internship 2

1. Internship time and arrangement

Our internship starts from 19 weeks to 20 weeks. Due to some delays during the period, our internship also made some temporary adjustments. The specific arrangements are divided into the following aspects: first, we hold a mobilization meeting; second, we understand the physical measurement map, the meaning of the icons, and the basic drawing methods and requirements of the physical measurement map; third, a senior brother leads us to understand some simple measurements methods, and learned about professional terms such as point selection and deployment control. Under the leadership of my senior brother, I initially learned how to use a total station. Such as: taking out the instrument, putting it back, centering, leveling, finding the target, etc. We completed the above process at the new campus of Guizhou University. Finally, under the leadership of Teacher Du, we went to the construction site (Lower Maitang Bay) to learn about it on the spot.

2. Purpose of internship

Although we have studied in college for a year, we still don’t know much about our majors. First, because our professional brothers and sisters are not on the same campus as us, which gives us fewer opportunities to communicate; second, we did not take professional courses in our freshman year; third, because we did not take the initiative to understand or go to Check information. It wasn't until July 2nd, when the internship mobilization meeting was held at the school, and I listened to Teacher Du and Teacher Wang's introduction to the profession and combined it with the surveying and mapping professional training plan we had received before that we had a further understanding. We know what we want to learn, which things must be mastered proficiently, and which ones should be regarded as minors and as understandings.

We all know that learning must have goals and plans. An ideal person must have his own goals and work hard for them. This internship is also for us to understand and understand the professional study in the future, so that we can arrange our next study plan more reasonably. Proper planning is necessary to remind you what your next goal is and what you should be doing now. It can give you a sense of urgency. Whenever you are a little lazy, take a look at your plan and remind yourself: all the efforts you put in now are for your future, and your hard work will definitely pay off. After this internship, we can develop a professional learning plan that suits us.

3. Gains from the internship

Through this internship and the exchanges with teachers and brothers during the internship, I have a better understanding of the surveying and mapping major we studied. . In this internship, we also got to know some commonly used instruments; and briefly understood the use of "total station". Learn about the teamwork and teamwork that goes into our surveying and mapping field operations. I think after this internship, I should make a professional study plan that is more suitable for myself.

Theory and practice are combined, and practice is the only criterion for testing truth. The use of instruments requires not only knowing the theoretical steps and processes, but also requiring us to train more, be more hands-on, pay more attention and be careful. Only by doing more operations can you become familiar with commonly used instruments. We need to be more careful during operation and develop good operating habits. This is a requirement for the use of precision instruments and valuable instruments. Including the removal, installation, uninstallation and playback of the instrument after use. Every step must be followed correctly. A little carelessness may damage the instrument. What’s more, today’s instruments are becoming more and more sophisticated and intelligent. When using the instrument, it is best not to modify it casually if we are not familiar with the programs in the team. If we modify it, it may destroy the data measured by others, or in serious cases, it may destroy the programs and commonly used data set inside. Through the understanding of this internship, we should exercise more ability to deal with emergency problems. There are many things we need to learn and sell now. In addition to the study of professional knowledge, we should also learn more commonly used knowledge and knowledge that is not closely related to the profession, but will be helpful to our future development. When learning programming, you must learn to use existing formulas to write program calculations for calculation methods and programs that are not available on the instrument. This will not only improve work efficiency, but also reduce errors and calculation errors.

Errors are inevitable, but we can minimize them. This way your data is more authoritative.

If plans cannot keep up with changes, it is necessary to lay a solid professional foundation. Maybe some students say that this is not their choice or their favorite major. But for now, since you are here, you can study with peace of mind. Real life is so complicated and many things are not what you like but you have to do it. Try your best to discover the aspects of your major that interest you, cultivate professional interests and work hard for them.

Brothers are united and their hearts are broken. Unity is strength, and surveying and mapping requires a strong team spirit. Many times your personal ability is not directly proportional to your work efficiency. Because this kind of efficiency requires teamwork. Whether I am studying next or working in the future, I must integrate into the team as quickly as possible and work well with the team. Learn to learn. If you don’t understand something in your future professional studies and future work, you should boldly ask questions and communicate more with experienced people. Only in this way can you improve yourself.

Through this internship’s understanding of the profession, you can make a plan for yourself. Maybe you're not used to making overly specific plans. It doesn't matter, you can make a personalized plan that suits you according to your own needs, which area I want to go in the future, and what standards I want to achieve after graduation. You will have a clearer understanding.

On the last day of this internship, we went out to work on the Maitang Bay demolition and resettlement project. Here we learn about an important step in construction for our profession? Staking out. I also asked the teacher about the working time periods of our major in construction projects and what we have to do during each time period. One is the engineering planning measurement before construction, the setting out during the construction process, the acceptance measurement and deformation monitoring after completion. Understand the high-precision measurement applications of tunnels and bridges. Mine surveying and mineral resource extraction surveying.

Although we have not yet learned professional knowledge, we do not understand some professional terminology and professional things. But such internship opportunities are hard to come by. The students cherished it very much and took it seriously during the internship. I still remember that on the afternoon of the last day, all the students were studying under the scorching sun. Teacher Du also patiently explained under the scorching sun.

Surveying and mapping requires hard work, carefulness, patience, and determination.

Try your best to complete as many tasks as possible in good weather! I believe that through this internship, all our classmates will have a deep understanding of it! ;
