Sophomore summer practice report, running on the construction site of an industrial park, should write a social practice report, about two thousand words, of course, original.

College students' holiday practice report

I had the honor to visit the expansion project of xxxxx this time. When I went there, most of the construction there was nearing completion, but some parts were only half finished. As soon as I arrived at the construction site, I saw the living area of the construction site. The door of the construction area also says that no one can enter the construction site without a bag. Of course, the slogan "Safety responsibility is more important than Mount Tai" is written on the protective net outside the main structure of the information building. It can be seen that in building construction, the first thing to pay attention to is safety. In the past, many industrial accidents and deaths were caused by the fact that production enterprises did not pay attention to the safety of migrant workers, which brought great losses and injuries to workers and enterprises. At the same time, in order to ensure the smooth progress and safety of the construction, the construction site should be surrounded by brick walls, and only vehicles and internal personnel under construction can enter and leave.

Walking around the construction site with my uncle who is the project manager, we stepped on a ladder made of steel pipes and iron nets and began to feel very dangerous, surrounded by steel pipes or iron bars sticking out. 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. I watched him inspect the finished house, but I didn't know anything. I asked him what he was looking at and why. As time goes on, there are more and more problems. I feel that I have studied in college for half a year and I feel that I have learned nothing. I don't know if this is a personal problem or if everyone is the same.

Next, take me to see their workers mixing concrete on site. The cement used by their workers passed the stability test. Through the understanding and study of concrete, I got some information about a material that is almost inseparable in modern architecture: (1) Concrete is one of the most important civil engineering materials in the contemporary world. It is an artificial stone material which is made of cementing material, aggregate and water in a certain proportion, stirred and vibrated, and solidified under certain conditions. Concrete is rich in raw materials, low in price and simple in production technology, so it is used more and more. At the same time, concrete has high compressive strength, good durability, wide strength grade range and wide application range. It is not only used in various civil engineering, but also used in shipbuilding, machinery industry, marine development and geothermal engineering. Concrete is also an important material. (2) Early curing of concrete: The common cracks in mixed nun soil are mostly surface cracks with different depths, which are mainly caused by temperature gradient and sudden drop of temperature in cold areas. Therefore, the protection department of concrete is particularly important to prevent early cracks on the surface. From the point of view of temperature stress, moisturizing should meet the following requirements: 1) to prevent the temperature difference between the inside and outside of concrete and the slope of concrete surface, and to prevent surface cracks. 2) In order to prevent concrete from freezing, the lowest temperature of concrete during construction should be no lower than the stable temperature of concrete during use. 3) Prevent the old concrete from supercooling, so as to reduce the constraint between the new concrete. The main purpose of early curing of concrete is to maintain suitable temperature conditions, thus achieving two effects. On the one hand, it can protect concrete from adverse temperature and humidity deformation and prevent harmful cold shrinkage and dry shrinkage. On the one hand, the hydration of concrete goes smoothly to achieve the designed strength and crack resistance. Appropriate temperature and humidity conditions are interrelated. Moisturizing measures of concrete often have moisturizing effect. Theoretically, the moisture contained in fresh concrete can completely satisfy the hydration of cement, and the surface concrete is most easily and directly affected by this adverse effect. Therefore, the first few days after concrete pouring is the key period of maintenance, and more attention should be paid in construction. Therefore, in the process of construction, we should handle these incidents carefully and deal with them according to different situations.

As a college student who has just come into contact with professional knowledge, it is unscientific to come into direct contact with advanced professional knowledge before studying professional courses, so it is necessary to make a summary after the internship.

The so-called practice is the only criterion for testing truth. By standing by, I have closely observed the whole construction process, and I can face the constructors face to face to see how they construct and how to turn the model on the drawing into a beautiful building, and I have learned a lot of practical and concrete construction knowledge, which are often very important basic knowledge that I seldom contact and pay attention to at school.

Although I have little knowledge, the practical experience I have gained will benefit me for life, and will be verified in practical work after graduation. I will continue to understand and appreciate the knowledge I have learned in my internship, and I will continue to apply the theoretical knowledge and practical experience I have learned to my future practical work, so as to fully display my personal value and life value. Strive to realize my ideal and bright future.

In fact, as a student, I want to study not to pass the final exam, but to acquire knowledge and work skills. In other words, studying at school is to meet the needs of society and to ensure that I can finish my future work and make contributions to society through study. However, there is a big gap between stepping out of the ivory tower and stepping into society. It's a blessing for me to be a buffer. Through practice, I know the actual needs of my work, which makes the purpose of learning more clear and the effect better.

In the next three and a half years of college study, I will study my professional knowledge harder, and at the same time I will enrich my other knowledge. After the internship, I found that knowledge is interlinked, everything is difficult, but I have to make great achievements, so I must learn more professional knowledge related to my major in the future. On the basis of learning this major well, I will try my best to get two degrees, and I must practice more. Try my best to improve my knowledge reserve and my life. The university said that not long is not short. I will use this limited time to complete infinite possibilities!

I think, if there is an opportunity, I will go to the construction site for internship every holiday in the future and learn more knowledge that can't be learned in textbooks. That's real wealth.
