Engineering survey practice summary model essay 2000 words

I majored in construction engineering at the university. In the continuous study, I feel my own shortcomings. I need more internships to supplement my knowledge and find more learning methods in the internship. These are all things that we should do well. Only through continuous practice can we learn more. I hope I can do this in my internship:

(A) the purpose of the internship

(1) Improve the planning, organization and management ability of independent surveying and mapping work, and cultivate good quality and professional ethics.

(2) Be familiar with the working principle of level and theodolite.

(3) Consolidate the knowledge of classroom teaching, deepen the understanding of the basic theory of Control Surveying, guide the operation practice with relevant theories, integrate theory with practice, improve the ability of analyzing and solving problems, make the basic content of Control Surveying get practical application, and further consolidate and deepen the learned knowledge.

(4) Through practice, be familiar with and master the operation procedures and measurement methods of the third and fourth class control survey. (5) Master the basic skills of processing and controlling survey results with survey adjustment theory.

(2) Preface

From June of 16, we carried out the engineering survey practice for 14 days. The content of this internship is the practice of engineering survey knowledge, and the requirement of the internship is to let each student basically master the actual operation of engineering survey. Compared with previous classroom practice, this practice is more concentrated in time, wider in content and more systematic in procedure. Starting from the actual production control and measurement, deepening the further understanding, mastery and comprehensive application of book knowledge is to cultivate our quality of integrating theory with practice, independent work ability, comprehensive analysis and problem solving ability, organization and management ability. It is also a concrete, vivid and comprehensive technical practice.

On the first day of internship, Mr. Liu mobilized us to practice. At the mobilization meeting, Mr. Liu emphasized the importance of this internship and analyzed the difficulties caused by complex geographical conditions and dense buildings. And encourage students to overcome difficulties and complete this internship. It also explains the matters needing attention in the operation and relocation of the instrument, and requires that the internship spare parts be kept well during the internship. The instruments needed for this internship mainly include level, spirit level, tripod and theodolite. On that day, we officially started outdoor measurement.

(3) Practical suggestions

The two-week study of engineering survey has ended. Through this internship, I deeply realized the importance of integrating theory with practice. The survey area is near the Student Activity Center of Shuang Fu New District Jiaotong University. Because the plan to be drawn is relatively large, in order to complete the task as soon as possible, our group worked overtime on Saturday and Sunday to investigate. During the investigation, we didn't feel tired or hard, but we could enjoy ourselves.

Measurement is first and foremost an accurate job. By studying surveying in class during my school days, I have formed the basic and theoretical outline of surveying in my mind, and the purpose of my internship is to link these theories with practical projects. Surveying is a science that studies the shape and size of the earth and the points on the ground. In essence, the main task of measurement is to determine the position of the ground target in three-dimensional space and its change with time. In the information society, the role of measurement is becoming more and more important. As the foundation of GIS, the survey results provide the most basic spatial position information. The construction of information superhighway, basic geographic information system and various thematic and professional geographic information systems urgently requires the establishment of a unified standard and shareable survey database and survey result information system. Therefore, surveying has become the most reliable and accurate means to acquire and update basic geographic information. There are many classifications of surveying, such as general surveying, geodesy, photogrammetry and engineering surveying. As a student of architectural engineering department, we should learn all aspects of measurement. Surveying and mapping is the basis of these professional knowledge.

(4) Practice summary

Through this internship, I learned the practical ability of measurement and had more endurance in the face of difficulties; I also learned the unity and tacit understanding between groups, and also exercised my mapping ability.

1. In addition to being familiar with the use of instruments, understanding the sources of errors and measures to reduce errors, we should also master a set of scientific measurement methods, and follow certain measurement principles in the measurement, such as the working principles of "from whole to part", "first control part" and "from high to low" to achieve "step by step verification". Doing so can not only prevent the accumulation of errors and find them in time, but also improve the efficiency of measurement. Through practice, I really learned a lot of real things, such as being more proficient in the operation of measuring instruments and leveling, and learning things that I can't do in class, such as drawing digital topographic maps and measuring damaged parts, which greatly improved my hands-on and brain-thinking ability.

Second, familiar with the use of level and theodolite, familiar with the various methods of using level and theodolite, and master the inspection and calibration methods of instruments.

Thirdly, in the process of checking and correcting data, we know the sources of various measurement errors, mainly including three aspects: instrument error (determined by the instrument itself, which is an objective error source), observation error (caused by the technical level of personnel, which is a subjective error source) and external influence error (influenced by external factors such as temperature and atmospheric refraction, which is constantly changing and difficult to control, which is a variable error source). Understand how to avoid measurement errors and limit the methods to reduce measurement errors, that is, to do:

(1) Appropriate high-precision instruments should be selected for instrument selection.

(2) Improve the measurement level and reduce the error level.

(3) Processing data by various mathematical methods to reduce errors, such as temperature correction, ruler length correction, multiple average measurements, etc.

This internship gave me a good overall feeling because I learned a lot. No matter what kind of internship, as long as we can find different learning methods and internship paths, we will certainly learn a lot in the process of internship. I believe I can do it well. In fact, the internship is really good, but it's a pity that many people don't realize the benefits and are still enjoying it. Sorry, I will be myself!
