The weather of Datong Lake in Yiyang

The following can be studied, which was written by an intern in our company.

At the beginning of this summer vacation, I started a tense summer vacation practice. In order to subsidize life, reduce family burden and improve practical ability, I am going to work with my classmates. . When I told my parents that I was going to work, they were all surprised: in their eyes, I was still a child and I didn't like to talk very much at ordinary times. Besides, I have never been far away, so I can go out to work alone. I'm sure I can't stand it. I'll go home in a few days. I didn't expect myself to be like this in their eyes. I have no choice but to find a suitable job near my home.

"No practice, no right to speak", only personal experience will have that extraordinary feeling. My summer vacation this year is different from last year. In fact, the school requires us to actively participate in social practice, just to let us get in touch with society in advance and understand it, so as not to lose the focus of life when we really step into society, so I decided to really get in touch with society this year and taste the ups and downs of society.

After running for a few days, I went to work in Qian Shan Red Construction Company under the introduction of my relatives and friends. Qian Shan Red Construction Company has built two commercial houses in Datong Lake District, Yiyang City.

My job is mainly responsible for on-site safety supervision and registration of materials in and out, as well as providing consultation for customers who come to buy houses. In order to do a good job, the boss introduced me to the project manager of the construction site, an architect with more than ten years of rich experience. I asked the project manager to give me a simple induction training, and the manager told me a lot of experience in construction and safety supervision. With the accumulation of experience, my working ability has improved a lot, which can be said to be of great help to me. Every time I sell a house, every time I get into a car full of materials, every time I register, and every day's work is over, my self-confidence is invisibly strengthened.

I remember on the first day of work, I didn't talk much, I didn't know how to receive the customers who came to buy a house, and I couldn't let go of the workers on the construction site. On the first day of summer vacation, I went to work and ended up with my * * * * and questions. Sometimes if you don't do well, you have to put in a good word for your customers, and the boss will criticize you. The weather is very hot in summer, and the site conditions and food are not very good. I tried to quit several times, but I persisted and worked hard. Facts have proved that if you persist, your life can be more substantial. It turns out that "self-reliance" is both a challenge and a pleasure. I can assure you that I can live a better and more fulfilling life than before!

In my work and life, I also understand a lot: in the management of the construction site, it is inevitable to blame the subordinates. Blame should also be used in an appropriate way, not only to blend in with the workers, but also to safeguard their dignity. Even so, it taught me a valuable lesson. It makes me understand that you must be calm when others criticize you or you listen to others' opinions. Only in this way can you show that you are really listening to him. Although it's hard to be criticized, make it clear that you really accept their criticism. Because only in this way can we learn from failure and pave the way for future success. We should learn to get up from where we fell. That's what I should do.

I also learned interpersonal and interpersonal skills from my work. I can see my own value in interpersonal communication. People are often very persistent, but if you only ask about cultivation and don't ask about harvest, then you will certainly make many friends. Treat friends, never haggle over every ounce, never force them to pay the true feelings equivalent to yours. You must know that giving is more pleasant than receiving. No matter what you do, you must have initiative and enthusiasm, have confidence in success, learn to communicate with people around you, care for others and support others. The days of working, there are joys and sorrows, there are joys and sorrows, maybe this is the whole life of working. I don't know how many part-time workers have felt this way, but generally speaking, this part-time life is an important step towards society in my life, which is worth remembering.

Now that I think about it, I have gained a lot from working in the summer vacation. What I have learned about life is something I can't understand at school, and it is also a treasure for me. Nowadays, college students are no longer "hot items" in the talent market, and almost all employers require work experience in recruitment conditions. Therefore, college students should not only have theoretical knowledge, but also the accumulation of work experience is equally important for finding a job in the future. It's simple. To apply for a job with the same academic qualifications, the company certainly pays more attention to personal relevant work experience. The employment environment is not optimistic, the form of competition is becoming increasingly fierce, facing anxiety and pressure, so

With college students like me, I chose to work in the summer. Although the summer vacation is only 1 month, during this time, we can experience the hard work, exercise our will and accumulate some social and work experience. These experiences are "intangible assets" owned by a college student, and their functions will be revealed at critical moments.

In addition to learning book knowledge, college students also need to participate in social practice. Because many college students are sober enough to know that people who "don't listen to things outside the window and read only sage books" are not the talents needed by modern society. College students should cultivate the ability to think independently, work independently and solve problems independently in social practice. By participating in some practical activities, we can consolidate the theory we have learned and increase some knowledge and skills that books can't learn. Because the ability to transform knowledge into reality depends on practical experience and exercise. Facing the increasingly severe employment situation and the ever-changing society, I think college students should change their ideas, not simply take summer jobs as a means to earn money or accumulate social experience, but more importantly, take the opportunity to cultivate their entrepreneurial and social practice abilities. Nowadays, employers pay more and more attention to college students' practical ability and ability to communicate with others. As a college student, as long as he can bear it, he should seize every opportunity, measure himself correctly, give play to his strengths, and get on the right track as soon as possible after entering the society. In this summer's work, I learned the importance of integrating theory with practice, and gained a lot, which has great inspiration for my future life and study. This part-time job is a beginning and a starting point. I believe that this starting point will make me gradually move towards society and maturity.

As far as the impact of cracks in cast-in-place slab on building construction is concerned, micro-cracks in cast-in-place slab will not affect the engineering quality, while excessively wide cracks will cause the corrosion of steel bars in concrete, reduce the durability of the structure, destroy the appearance of the structure, affect the normal use and seriously affect the safety of the structure. According to the current building code in China, the maximum allowable crack width of cast-in-place components (such as cast-in-place slabs) under normal circumstances is 0. 3mm, under normal circumstances, the maximum allowable crack width of roof truss, heavy crane beam and cracked general prestressed member is 0. 2 mm.

Treatment of cracks: first, before the treatment of cracks, we should comprehensively analyze the nature of cracks and the reasons why this article comes from Xiaocaofan. And take corresponding measures according to different reasons. When dealing with cracks, we should not only ensure the original bearing capacity of the structure, but also ensure the integrity and waterproof and impermeability of the structure. Second, the cracks caused by load should be strengthened by increasing the thickness of the floor, sticking carbon fiber or sticking steel mesh according to the Technical Specification for Strengthening Concrete Structures or other relevant specifications. III. General treatment of non-structural cracks: (1) For surface cracks, a thin layer of mortar can be coated on the surface, or epoxy mortar and epoxy glass cloth can be coated on the surface of cracks for sealing treatment. (2) The joint width is less than 0. 3mm, can use the method of grouting cement or chemical slurry for crack treatment. (3) The joint width is less than 0. 3mm cracks can be treated by measures such as joint filling combined with concrete reinforcement. Four, the reinforcement scheme of major structural cracks, put forward by the design unit, the construction unit to organize experts to demonstrate before implementation.

Technical measures for crack control of cast-in-place slab in residential buildings: material is the foundation, design is the premise, construction is the key, and management is to ensure crack prevention of cast-in-place slab in residential buildings.

1. The preferred material for cast-in-place slab reinforcement: (1) HPB335 grade hot-rolled reinforcement with good ductility, toughness and weldability. (2) The sand used for concrete should be strictly controlled, and the silt content of stones should be controlled within 2%. Fine sand and mud sand are strictly prohibited.

2. Design: (1) The building plane of the house should be regular to avoid plane protrusion. Under special circumstances, irregularities should be treated with double-layer bidirectional steel mesh or hidden beam. (2) The roof panel should be provided with an insulation layer, and the thickness of the insulation layer should be calculated according to the parameters of the material, and then its thickness should be determined. (3) The waterproof layer of rigid roof shall be provided with frame joints according to the specification requirements and roof joint details, and sealed waterproof materials shall be embedded in the frame joints. (4) When the plane of the residential building is complex or the building length exceeds the expansion joint spacing specified in the code due to engineering needs, the corresponding structural calculation software should be selected to analyze the temperature of the concrete floor. Determine the location of temperature stress concentration in order to take corresponding technical measures. (5) Appropriately increase the slab thickness, with the thickness of one-way slab not less than 1/30L, two-way slab not less than 1/35L, minimum thickness of floor slab not less than 90mm and minimum thickness of roof slab not less than 100mm. (6) The setting of structural expansion joints and the thickness of protective layer of concrete members in residential buildings should be strictly implemented in accordance with the provisions of corresponding codes. (7) When the strength grade of cast-in-place slab is greater than C30, high-performance concrete should be preferred.

Under the guidance of Sun Chaofa and Xiao Sixi, I learned about the rules and regulations and various engineering procedures related to the construction site. Understand the design intention, design scheme and construction details by reading the drawings; Understand the practical problems that may occur in engineering construction and learn practical solutions.

(1) architectural knowledge

Visiting single buildings and buildings in East and South Yards, the analysis is as follows:

The overall layout of the school adopts the systematic layout of unit mode, which is conducive to interdisciplinary and resource sharing. Each building group develops in an orderly way, each group has its own center, and a convenient walking system is connected with adjacent groups to form multiple independent and efficient operation systems. At the same time, it also improves the traditional closed and independent layout of each major, and meets the requirements of interdisciplinary, efficient and convenient disciplines and the requirements of relatively independent functions of each part in a holistic and independent way. The planning of the new campus is guided by eco-environmental awareness, and people and nature coexist. Make full use of the existing topography, create an elegant and dynamic campus cultural atmosphere, and meet the requirements of energy saving, ventilation and environmental protection as far as possible in the single layout. Make full use of the existing natural conditions of the base and adjust measures to local conditions. Planning not only protects the original environment, integrates the artificial environment with the natural environment, highlights the hierarchical sense of building group layout, but also strengthens the supporting design of campus environmental landscape, and also pays attention to creating the atmosphere of colleges and universities from a higher level, combining the creation of human environment with the protection of natural environment.
