Field practice summary model essay 1500 words.

The full internship life is over. I believe you must have a lot to share. You might as well sit down and write an internship summary. Is it impossible to write without a clue? The following is a summary essay of 1500 words that I have carefully compiled, hoping to help everyone.

Summary of on-site internship 1 This is the first internship I have experienced in my life, which is unforgettable. It will comprehensively test my abilities in all aspects: study, life, psychology, body, thought and so on. Test whether I can apply the theoretical knowledge I have learned to practice. It is related to whether I can succeed in this challenging society in the future, and it is also the key to building confidence, so my investment in it is also 100%! The whole week's internship is over, and I still have a lot to gain during this week. It is necessary to sum up after the internship.

Through a week's internship, we visited several residential sites (Shangzuo, Oriental Garden, etc. ) I went to Tangshan Ring Expressway again. Here, I was deeply impressed by the exquisite layout of Shangzuo, the personalized design of oriental gardens and the perfect shape of expressway overpass. Below, I will summarize the specific internship as follows:

I learned a lot of practical knowledge through practice. The so-called practice is the only criterion for testing truth. By standing by, I observed the whole construction process at close range, and I could face the constructors face to face to see how they constructed and how to turn the model on the drawing into a beautiful building, and I learned a lot of practical and concrete construction knowledge, which I seldom contacted and paid attention to at school, but it was also very important basic knowledge.

That day, we stepped on a ladder made of steel pipes and iron nets and began to feel dangerous. There are steel pipes or iron bars sticking out everywhere. The formwork and supports on the second and third floors have been removed, and it can be clearly seen that the pillars supporting the upper weight are so big that we all feel that the height of the floors has become smaller. There are many constructional columns around the load-bearing columns to increase the strength of the wall and avoid the collapse of the wall because of its long length. Along the way, we saw that the supports of the upper floors were not removed. These supports are made of steel pipes and templates. Steel pipes are very dense, and obviously need a lot of support to bear concrete slabs and beams with no strength at all.

In architecture, I found many cracks in the joints of some buildings. After the teacher's explanation and the information I collected, I gained a lot.

Causes and treatment of concrete cracks This is a very complicated problem. Let me talk about my opinion: There are many reasons for concrete cracks, mainly the change of temperature and humidity, brittleness and unevenness of concrete, unreasonable structure, unqualified raw materials (such as alkali-aggregate reaction), template deformation, uneven settlement of foundation and so on. In the process of concrete hardening, cement releases a lot of hydration heat, the internal temperature rises continuously, and the surface produces tensile stress. In the later cooling process, due to the constraint of foundation or old concrete, tensile stress will appear in concrete. The decrease of air temperature will also produce great tensile stress on the concrete surface. When these tensile stresses exceed the crack resistance of concrete, cracks will appear. The internal humidity of many concrete changes little or slowly, but the surface humidity may change greatly or greatly. Such as poor maintenance, sometimes dry and sometimes wet, surface shrinkage and deformation are constrained by internal concrete, which often leads to cracks.

Concrete is a brittle material, and its tensile strength is about110 of its compressive strength. The ultimate tensile deformation under short-term loading is only (0.6- 1.0) × 104, and it is only (1.2-2.0) under long-term loading. Due to uneven raw materials, unstable water-cement ratio and segregation during transportation and pouring, the tensile strength of the same piece of concrete is uneven, and there are many weak parts with low tensile capacity, which are prone to cracks. In reinforced concrete, tensile stress is mainly borne by steel bars, while concrete only bears compressive stress. If the edge of plain concrete or reinforced concrete has tensile stress, it must be borne by the concrete itself. In general design, no tensile stress or only a small tensile stress is needed. However, when the concrete cools from the highest temperature to a stable temperature during operation, it often produces considerable tensile stress inside the concrete. Sometimes the temperature stress will exceed the stress caused by other external loads, so it is extremely important to master the variation law of temperature stress for reasonable structural design and construction.

According to the formation process of temperature stress, the analysis of temperature stress can be divided into the following three stages:

(1) Early stage: Generally, it takes about 30 days from the beginning of concrete pouring to the end of cement exothermic. The two characteristics of this stage are that the cement releases a large amount of hydration heat, and the elastic modulus changes dramatically when setting. Due to the change of elastic modulus, residual stress is formed in concrete during this period.

(2) Mid-term: the period from the end of the exothermic action of cement to the cooling of concrete to a stable temperature. During this period, the temperature stress is mainly caused by the cooling of concrete and the change of external temperature, and these stresses are superimposed with the residual stress formed in the early stage. During this period, the elastic modulus of condensation does not change much.

(3) Late stage: the operation period after the concrete is completely cooled. Temperature stress is mainly caused by the change of outside air temperature, and these stresses are superimposed with the first two residual stresses.

The above is a summary of my internship. In the future practical work, I will work hard and strive to do all the work better.

Summary of field practice 12 On July 2, I set foot on the road to Xining, with an altitude of 2,300 kilometers and 2,600 meters and strong ultraviolet rays.

First of all, I would like to introduce my internship unit: No.4 Project Department of Hu Hai New District Electric Power Community in Xining City. The project was contracted by Tongzhou Construction General, a famous construction company in Nantong. The total cost of this project is 230 million yuan, with a total construction area of 65.438+0.28 million square meters. The whole project consists of ten 654.38+0.8-storey high-rise residential buildings and six underground garages.

I'm new here, I don't know anything, I'm at a loss Even walking on the construction site is a bit embarrassing. My head has been tilted down 45 degrees, and I am afraid of being attacked by my nails suddenly, so I can't take care of my head when I take care of my feet. It's true. It's very suitable for use here. Sure enough, I accidentally hit the scaffold. Fortunately, I didn't knock out my bag under the protection of my helmet. I have gained a lot of experience. Experience tells me that when walking on the construction site, we must always be careful, concentrate our thoughts, and always pay attention to all directions.

A month has passed, and from the beginning, I know very little about all departments, including security department, construction department, technical department, information department, finance department, project manager's office, office and party branch.

A month has passed, from initial hesitation and immaturity to vigilance and familiarity now. One month's exercise made me deeply understand the whole building process, from foundation excavation, foundation pit protection, main body completion, foundation pit backfilling, indoor and outdoor decoration to the completion of a building. Pay-off to all floors, mold making, steel binding and scaffolding coordination. In my mind, how a building rises from the ground is basically clear.

A month passed, and I learned a lot from the vagueness and ignorance of technical terms at the beginning. Pay-off, sweeping pole, horizontal pole, scissors, throwing pole, rotary fastener, butt fastener, right-angle fastener, step fastener, jacking wire, automobile pump, vehicle-mounted pump, diesel pump, shear wall frame structure, anchorage length, lap length, electroslag pressure welding and cold connection. There is also a lot of knowledge about setting out, which can be roughly divided into three types: floor setting out, leveling and elevation. Floor pay-off is for carpentry molding, leveling is for indoor doors and windows, and elevation is for better inspection of concrete thickness. I remember that in the first few weeks, I have been following the master to take the instrument to the scene to pay off the line. Electronic theodolite, electronic level and laser level, which are rarely contacted in school, have a chance to learn systematically here. Every day when you step on the initial setting concrete on the floor under the scorching sun, the ink in Mo Dou turns black several times. Later, I took the architectural blueprint to the construction site for comparison and took a tape measure to evaluate the construction quality of the construction site. Later, I studied management with the project manager. At that time, I felt that I was already half a builder.

Within a month, the leaders of Xining City inspected, the secretary of Qinghai Provincial Party Committee inspected, and Party A inspected twice ... Every time I felt the atmosphere behind me, my mind ran fast while feeling it, and I wrote down the shortcomings of the construction site and the opinions of the leaders.

A month passed, and I learned experience and methods. I broke a windbreaker and a pair of pants, and it was very painful. My face is black, and my cat's elbow is there. When I was familiar with the scene, Mr. Ding informed me to go to Huayi Real Estate to help (Huayi Real Estate is the general party of Tongzhou Construction)

Real estate articles

I am very excited about the short learning opportunities of Huayi Real Estate Company. When I was struggling at the scene, Mr. Ding informed me to go to the finance department of Huayi Real Estate for a few days. When I first entered Huayi, the office atmosphere infected me. Everyone is busy with their own affairs, and the engineering department is discussing the progress, quality and safety of the construction site. The business department is studying the plan, and the finance department is carefully reconciling. Everyone doesn't care or even despise me, a young man who just entered the company. I secretly refused, and one day I would sit on their heads and point fingers. I hope that day will be in the near future. One week's internship is very short. Now I can say: Huayi, you are nothing in the real estate industry. Here I list the background of Huayi. Huayi Company was established in 20XX 165438+ 10, which is a subordinate department of the provincial government. At that time, due to functional needs, a team composed of several section chiefs and some office staff was transferred from various units in Qinghai. The company's development qualification is only level 3, and the registered capital is only10 million.

preface

I will set foot on the road back to Nanjing tomorrow. 28-hour train, long journey, full of thoughts. I end this article with the advice given to me by the director of Tongzhou Construction Bureau, which is also the advice for all civil workers: whether you enter the construction unit or real estate in the future, or even the construction bureau of the Construction Bureau. You must exercise in the construction site for 3 to 4 years, and carry forward the spirit of not being afraid of hardship, fatigue and dirt, so as to accumulate experience and meet future challenges!

Summary of field practice 3 I am the captain of the seventh investigation team, which has nine members. In addition to operating and managing instruments, I am also responsible for making investigation plans and coordinating the division of labor and cooperation within the management team. In addition, it is my job to wake up the players every day. As the number one leader, the task of leading measuring tools and stepping on the construction site naturally falls under my name. On the first morning, after the teacher explained the relevant precautions to us, he led the group leaders to the scene for investigation, and then assigned tasks to each group. My task is: the 20 th to 24 th floors of the staff area.

Surveying and mapping a topographic map of 250m250m, plus an original survey data. At half past two in the afternoon, I led three team members to get tools. Because I only touched the dj6 theodolite before, I got the dj2 with higher accuracy. Before we learned how to use it, it was just an advanced toy, worth tens of thousands of dollars. I've been pretending, but it took me more than ten minutes to watch dj2, and then I was responsible for giving lectures to my team members. I felt guilty as a team leader for the first time. But fortunately, I finally learned it, and later I thought it was quite simple to use. After teaching a team member, I walked around the survey area with paint and another team member, and selected 9 control points. Maybe we were too excited, or maybe we forgot all the precautions listed in the textbook when we selected the points for the first time, which brought a lot of trouble to the following measurement homework. In fact, the choice of control points is of great significance, and losing this move will have a very favorable impact on the next situation. The following are the basic requirements for the selection of traverse control points, and the extracts are as follows for warning!

1, adjacent traverse points have good visibility and flat terrain, which is convenient for angle measurement and ranging;

2. The traverse points should be selected in solid and stable soil, which is convenient for keeping marks and placing instruments;

3. Traverse points should be selected in places with high terrain and broad vision, which is convenient for surveying and mapping lofting;

4, the length of each side of the wire should be roughly equal, should be close to the average length;

5, traverse points should have enough density, uniform distribution, in order to control the whole survey area.

We did well at 2 o'clock, 3 o'clock and 4 o'clock, but 1 o'clock and 2 o'clock were not rigorous. In the subsequent measurement, these two errors were constantly amplified, and finally they were amplified to the point where they had to be retested. I think, through this incident, I deeply understand the meaning of the sentence "If I had known this, why should I have done it in the first place". That afternoon, nothing was achieved except the ordinary leveling of traverse points. After work, I went back to the dormitory and did indoor calculations. The result was shocked. The height difference of the conductor has reached an astonishing 90 mm, so it seems that he will go to the early shift the next day.

The next day, I got up early and re-measured the elevation of the traverse point. The results are satisfactory and the closure error is within the allowable range. I took a wrong step on the first day, so I have to be careful today. The main task today is to measure the internal angle and sight distance of traverse points. These two sets of data are indispensable when calculating the coordinates of traverse points, which is related to success or failure. Another classmate and I take turns to take up our posts and take charge of observation; Other students are responsible for setting rulers and records. For the measurement work with high precision, once it is millimeter, it may be thousands of miles away, and the two links of observation and ruler determine the accuracy and correctness of the final measurement result. As an observer, at the beginning, the centering and leveling of theodolite really took me a lot of brains. I've always felt that centering and leveling are like fish and bear's paw, and there's no way to stuff them together. Later, through the help of various channels, learning and self-exploration, I finally got something, and then it was a piece of cake. Length is also important. Thank God for giving our team a ruler. This ruler is as steady as Mount Tai, and the ruler in his hand is like the sea god of the East China Sea Dragon King (commonly known as the golden hoop stick)-motionless. And this is what the measurement work needs most. In this way, we matched each other and measured the internal angles and distances of nine traverse points. I did an indoor calculation at night, and the result scared me again. Finally, the difference is within the allowable range. The allowable angle closure difference is 120, but the measured closure difference is less than 5, which can be basically ignored. This is a blessing. But "basically" does not mean "completely". If there are any mistakes, they must be corrected! The task at night is still data processing, which is exactly what I am not good at, but the team has its own data processing talents, so I don't have to bother.

As I said before, in China, many things will fall victim to exams, and measurement practice is inevitable. Because two important exams were interspersed in the next few days, the survey work could not be carried out normally, but the survey of several buildings was completed. During the preparation period, we take the time to calculate the coordinates of traverse points and draw them on the drawings to prepare for the next work.
