No one answered the graduation internship thesis. I'll see if anyone can help me write my graduation internship report. . . I'm just teasing the pen. . Almost like writing a composition. Is there anyone to help? I'm in a place First, internship background

(1) Brief introduction of Xicheng high-speed railway.

The total length of Xicheng high-speed railway passenger dedicated line is about 643 kilometers. Newly-built Xi 'an-Jiangyou section of Xicheng Passenger Dedicated Line will be connected with Jiangyou and Chengdu-Mianyang-Leshan intercity railways. In the future, newly-built Xicheng Passenger Dedicated Line will be built from Jiangyou to Chengdu. The Xi 'an-Jiangyou section of the newly-built Xicheng Passenger Dedicated Line is 5 19 kilometers long, including 343 kilometers in Shaanxi and 3 17 kilometers in Sichuan. The total investment of the project is estimated to be about 65 billion yuan. Xicheng high-speed railway is built according to the level of passenger dedicated line, with a design speed of 250 kilometers per hour, and undertakes long-distance passenger flow between North China, Shaanxi and Southwest China, taking into account some intercity passenger flows along the line. Starting from xi 'an, crossing the Qinling Mountains, passing through Hanzhong, Shaanxi, crossing Micang Mountain, entering Sichuan, connecting with Chengmianle Passenger Dedicated Line, passing Guangyuan to Jiangyou, Sichuan, and directly reaching Chengdu, greatly shortening the straight-line distance between Xi 'an and Chengdu, two central cities in northwest and southwest.

(2) The purpose and significance of the internship.

1. Graduation practice is an important way to integrate theory with practice, an important link to improve students' political and ideological level, professional quality and practical ability, and it is of great significance to cultivate skilled and applied talents who adhere to the four cardinal principles, have ideals, are ethical, have education and are disciplined. Students go to the society through internship, get in touch with practice, understand the national conditions and people's feelings, and enhance the people's labor concept and their consciousness, dedication and sense of responsibility in participating in economic construction; By going deep into the grass roots, we can deepen our understanding, consolidate the professional knowledge we have learned, further improve our ability to understand, analyze and solve problems, and make ideological and professional preparations for going to society and serving society in the future.

2. Consolidate the theoretical knowledge learned in class and master the level through field measurement practice.

Basic operation of theodolite, mastering observation of traverse survey, trigonometric leveling and fourth-class leveling.

And learn how to carry out field topographic control survey, topographic map drawing and splicing,

At the same time, we also experience the life of field work and cultivate teamwork ability.

Second, the specific work content of the internship stage

(1) Look at the map.

The first step of construction technology management is to understand drawings, because drawings are the basis of on-site construction. To know the drawings, we should fully understand the designer's intention and find out the problems in the drawings.

1, picture reading stage, the procedure is as follows:

1). Coarse first, then fine: first look at the plane, elevation and section, then look at the details.

2). First small, then big: look at the small sample first, then look at the big sample.

3) Building first, then structure: Look at the architectural drawing first, then at the structural drawing, and check whether the axial positions of the architectural drawing and the structural drawing are consistent.

4). First general, then special: first look at the general parts and requirements, and then look at the special parts and requirements.

5). The drawings, general instructions and details in the drawings should be viewed together, and attention should be paid to whether there is any contradiction between the drawings and instructions, whether the regulations are clear and whether the requirements are feasible.

6). Combination of civil engineering and installation: Please refer to the installation drawing when looking at the civil engineering drawing first. What's on the installation drawing and whether it is indicated on the civil engineering drawing, especially the embedded parts and holes, and the dimensions should be checked clearly.

7). Combination of drawings and actual conditions: When you are familiar with drawings, you should consider whether the construction conditions can meet the design requirements, whether the design drawings are in line with the site conditions, and whether the design drawings are in contradiction with the construction operation and specifications.

8). On the basis of reading pictures, take notes while reading.

(2) Surveying and setting out of road and bridge engineering.

1, measure the horizontal distance with total station.

With the rapid development of measurement technology, the use of rangefinder or total station is becoming more and more common. Moreover, it is relatively simple and convenient to use rangefinder or total station in construction survey at present.

Precise method. With automatic tracking function.

When the range finder measures the horizontal distance, the instrument automatically enters.

Perform meteorological correction and change the tilt distance to horizontal.

Directly display the distance. The specific method is as follows:

During the layout process, place the instrument at point A, as shown in Figure 2.

Measure the temperature and pressure and input them into the instrument. At this time, press the function key of measuring horizontal distance and the function key of automatic tracking, and a person will stand near the finish line with a mirror rod. As long as the observer orders the lens holder to move the prism back and forth along the known direction line, the observer can measure the horizontal distance on the display screen of the rangefinder in time. When the displayed value is equal to the known horizontal distance d to be measured, the end point can be determined.

2, polar coordinate lofting.

Polar coordinate method refers to the method of measuring the plane position of the point to be measured through the polar diameter and angle of the point in the established polar coordinate system, that is, according to the horizontal angle and horizontal distance. This method is suitable for theodolite or total station survey with rangefinder.

In the construction site, the polar axis is usually the edge of the conductor, the construction baseline or the main axis of the building; Pole on a point that has been calibrated in the field. During lofting, the horizontal distance d (polar diameter) from the point to the pole and the coordinate azimuth from the pole to the point to be measured are calculated according to the coordinates of the point to be measured and the water outlet angle (polar angle) is calculated according to the azimuth, and then the point is lofting with the sum of d, where the sum of d is called lofting data.

As shown in Figure 4, A and B are the existing control points on the ground, and the coordinates are, and respectively; In order to arrange point p, its design coordinates are. Then:

These include:

During layout, put a theodolite at point A, aim at point B, and first lay out the angle to get the AP direction line. Measure the horizontal distance d on this direction line and get the point p.

3, construction lofting.

Construction lofting mainly uses total station and polar coordinate method to set out the points we need. For subgrade protection, it is necessary to set out the protection positions of the opening toe, opening and slope of each platform on the left and right sides (the error is within 1 cm-2 cm. ) The bridge lofting needs to release the hole pile position of each abutment, bearing platform, step platform, pier, formwork and cushion stone. Abutment also needs to release abutment position, (the error should be within 1cm, and the part should be within 0? Within 5 cm. ) after the pay-off, to the construction personnel and operators on-site technical disclosure.

Third, the feelings and gains of internship

(A), the feeling of internship

This internship is mainly to gain knowledge and experience by working with the master and communicating with other construction workers. During the internship, I mainly studied on-site lofting. Now let me talk about my experience in lofting: lofting, also known as setting out, is to find the position of each part of the drawing on the actual land and mark it. Basic tools: level, electronic level, total station, prism rod, tape measure, marker pen, steel nail, hammer, etc. In the process of converting drawings into objects, lofting is one of the most important and critical steps. Therefore, for building construction, a good start is half the battle.

1, the quality of lofting directly affects the construction speed and quality. Some people say that it is normal to differ by 2cm when setting out. But the bridge lofting must be carried out in accordance with the specifications. In the process of lofting, you can't plan quickly, you should have enough patience and know every step. Only in this way can the lofting work be completed with high quality and high standard, and the construction personnel can be given correct information to complete the project with high quality.

2, the builder and technician cooperate with each other, * * * with the completion of the pay-off work, let other teachers more liberation process, to ensure the construction quality. In the process of construction, the lines will not be as clear as those on the drawings, so the construction personnel must know something about the whole construction lofting process, otherwise, once something goes wrong, the consequences will be unimaginable, because the previous process will affect the whole construction behind. Therefore, when installing the formwork, we must make clear whether the edges are correct, so that working together can not only learn from each other, but also improve the construction quality and speed. Let's work together in Qi Xin and Qi Xin.

(B), the harvest of the internship

My own understanding of construction engineering is as follows:

1. Theory is the foundation, and practice is the foundation.

Without a theoretical basis, it is impossible to correctly analyze and solve problems. Therefore, before our measurement practice, teacher Zhang explained the theoretical knowledge very carefully this semester, and our down-to-earth learning attitude made us master the theoretical knowledge well. For students majoring in construction engineering technology, they should not only have rich professional theoretical knowledge, but also have excellent practical operation ability.

2, clear goals, make plans.

A ship without a course will never reach the other side of success. Of course, if you have no goal in your work, you will never taste the joy of success, so we first made our goal clear in this measurement practice. Topographic mapping, building lofting, road circular curve measurement. If you have a clear goal, you should strive for it. We can't fight blindly, because "everything is established in advance, and it will be abolished if it is not predicted." Therefore, at the beginning of the practice, we made relevant plans for the process of measurement practice. In the end, we saved a lot of trouble. For example, the content and tasks we practice every day are different, so when we prepare the equipment, we only bring the equipment we need, instead of going to the practice site. Although this is a personal experience during the internship, we have benefited for life.

3. Establish a team consciousness of unity and cooperation.

Our internship can't be done by ourselves, but by our joint efforts. For example, in breakpoint measurement, it is necessary to stand with a ruler, the observer reads the data, the recorder records the data, and the draftsman draws a sketch. To this end, we need to let the team members establish a sense of unity and cooperation and successfully complete the internship task as soon as possible.

4, hard work, self-improvement.

As we all know, our students majoring in construction engineering and technology will generally work in the open air in the future, and it is inevitable that they will encounter wind and sun. Just like our investigation and practice this time, it is hot because it is summer. So we often use this time to go out early and return late, which requires us to go out early and return late. Although not used to it, it is our inevitable choice. Choose hard work and self-improvement. Finally, a hard work and a harvest, our team members exchanged ten days of hard work for the successful end of the internship.

5. Seek truth from facts.

Without rules, there would be no Fiona Fang. When we operate the instrument, we must carry out the measurement practice according to the normal operation. When we practice related content, we should also follow certain procedures. Otherwise, we will take many tortuous roads. This tells us that we must combine the times with regularity and think and solve problems with creative thinking. Of course, we should be pragmatic and keep making progress while strictly demanding.

Fourth, I need to improve my content in terms of professional quality and post comprehensive ability.

In this graduation internship, I also found some shortcomings and deficiencies, mainly including the following four points:

1, professional knowledge is not comprehensive enough. Although I have studied professional knowledge seriously at school, my current knowledge is not wide enough to be easily qualified for subway engineering work. Therefore, although I am going to work in the near future, I still want to regard work as the beginning of a new study. Only by studying in practice can I master more professional knowledge and skills.

2. Professional practical experience is far from rich. Due to the lack of professional practice time, it is difficult to apply what you have learned to practice, and the experience gained through practice is even scarcer. Therefore, in the future, we must seize the opportunity to learn from the predecessors engaged in water conservancy projects, and at the same time, we must change our own learning methods and attitudes, change the passive absorption learning style that relied too much on teachers in the past, actively learn from others and ask for advice, and at the same time strengthen our self-learning ability and problem-solving ability.

3. The application of professional knowledge in engineering is not flexible enough. Through this graduation internship, I really feel that the professional knowledge I learned before is not flexible. This is mainly because the knowledge learned has not formed a complete system, and these scattered knowledge points are difficult to use. Therefore, in the future, we should pay attention to accumulation and application in study and practice, so as to make the learned knowledge change from quantitative to qualitative and play a greater guiding role.

It's just that the theory is not well mastered, and it's only after the internship that I know I didn't learn well. I just took a look at it during the exam, in order to cope with the exam at school. After the exam, my mind went blank, and whether I want to use it in the future disappeared into my memory. My ability to be familiar with drawings is poor, and I can't imagine the three-dimensional appearance of plane graphics. Do not know the latest construction specifications. It is impossible to quickly judge whether the construction is right or wrong. Some construction sequences are still unclear, and the operation of each construction process is unclear. The ability to integrate theory with practice is poor, and little is known about the latest development of architecture.

Ten years of student life is coming to an end. During my internship in a famous company, I learned a lot. Adults say that there are always many "characteristics" in the newly graduated students that make the boss of the company have a headache. Now I finally realize it myself. As a student before, my main job was to study; Now I am about to enter the society. Obviously, my identity has changed, and so has my natural center of gravity. Now my main task should be to gradually shift from study to work. This internship period is like a transition period-the transition from students to office workers, which is a very critical stage. Looking back on my work during this period, I am not satisfied. I have thought about this. Learning experience is naturally a factor, but more importantly, the change of mentality has not been achieved. It is timely to find this deficiency now, because I understand what work is. In the next few days, I will work hard in this direction, and I believe I can erase those "features" that should not exist. Thanks to the guidance and teaching of the masters during this time, I have benefited a lot.

Five, internship units and projects (departments) problems found in the internship.

(A), strengthen internal management

1, pay attention to internal management: ensure safety and survival; Improve quality and development. Enterprises must be equipped with a strong management team.

2, do a good job in engineering cost accounting.

(2) Strengthen training.

1, I suggest strengthening the management knowledge training of project managers and improving the engineering management level of employees in a targeted manner. On the basis that each employee has at least one professional skill, the employees of engineering department should first strengthen the cultivation of knowledge in project management, planned operation and construction management, so that everyone has knowledge in project management, which will be more conducive to the development of management-oriented companies.
