Main structure detection and case analysis of construction engineering
1 Quality inspection and supervision methods for the main structure of construction projects The inspection work of the main structure of construction work is relatively complicated, and it is necessary for the construction enterprise to effectively manage the specific work to ensure the effective implementation of the inspection work. The engineering project management department needs to supervise all aspects of the inspection work to ensure that the detailed work is effectively implemented one by one. The quality inspection and supervision of the main structure of a construction project is mainly carried out through the following procedures. First, in the preparatory stage of quality inspection and supervision work, a supervision team needs to be established. In the process of detecting the main structure of the project, the situation is complicated, and it needs to be dealt with flexibly according to the actual situation, but the omissions caused by being too casual should be avoided. For the testing samples, it is necessary to strictly follow the quality testing standards and carry out targeted brake testing programs for specific work. Only when an effective program is established can the supervision team effectively manage the quality inspection supervision work according to the specific program. Second, the supervision team determines the supervision ideas according to the requirements of the relevant quality inspection standards and specifications, and draws up the detailed supervision plan according to the quality inspection plan. The planning strategy needs to be discussed jointly by the supervision team and the quality inspection team. After the content of the supervision plan is finally clarified, the specific plan will be issued to each supervisor to implement specific supervision arrangements and supervision responsibilities. At the same time, it is also necessary to inform the construction team of the quality inspection requirements and supervision plan, so that they can clarify the quality requirements and supervision measures, carry out construction in strict accordance with the quality inspection standards during construction, and cooperate with the supervision and management work to ensure that the quality inspection and supervision and management work is in place . In addition, the quality inspection work can be completed by inviting a professional inspection expert team to formulate a detailed professional plan for the main structure inspection work of the construction project to improve the quality inspection work level. Third, the completion acceptance stage of construction projects is very important. The key point is to separate the quality inspection and quality inspection work. This is because the inspection methods of the two tasks are different. The inspection and acceptance is to conduct a comprehensive evaluation of the inspection and ensure quality inspection. For the rationality of the work, the supervision team generally conducts inspection and acceptance alone. Once there are deficiencies in the detection work, they can be discussed by the supervision team.

Construction technology of prestressed anti-corrosion and anti-floating bolt
1 Project overview In a high-rise building, there are two single towers above the ground, each with 18 floors; the first floor is outdoors, and the roof of the basement is covered with soil 1m for greening land: 3 basement floors underground, the depth relative to the outdoor ground is about 12m: the column distance of the basement is at the owner's request, They are 10xl0m and 12xl0m respectively; in the preliminary design, the foundation adopts bored piles; the floor adopts beam-slab structure, and the thickness of the slab is 800mm. According to the survey report, the soil condition of the site is described as follows from top to bottom: (1) Artificial filling layer: the average thickness is 2.0m. (2) Silt layer: the average buried depth of the top surface is 2.0m, and the average thickness is 2.5m. (3) Silty clay layer: the average buried depth of the top surface is 4.5m, and the average thickness is 12.5m. (4) Strongly weathered rock formation: the average buried depth of the top surface is 17.0m, and the average thickness is 1.0m. (5) Moderately weathered rock formation: the average buried depth of the top surface is 18.0m, and the average thickness is 4.0m. (6) Micro-weathered rock formation: the average buried depth of the top surface is 22.0m, and the average thickness is not less than 6.0m. The groundwater level of the site where the building is located is relatively shallow, and the anti-floating water level of the groundwater is taken to be the same as the outdoor ground, and the floor anti-floating plays a controlling role. If the beam-slab structure is used directly to resist buoyancy, considering the beneficial effect of the self-weight of the bottom plate, the design value is taken as: 12xl0x1.2-0.8x24x0.8=129KN/m0. Taking the calculation and analysis of the 10xl0m standard floor as an example, the design theory of the 12xl0m is the same, so it will not be repeated here. Using C30 concrete and HRB335 steel bars, the diameter of the gluten bars is calculated to be 16mm and the spacing is 100mm. The crack width is 0.195mm: the bottom rib diameter is 20mm, and the spacing is 100mm.

Construction technology of deep foundation pit support in high-rise building engineering
With the continuous increase of urban population, most of the construction projects in the city adopt high-rise or super high-rise buildings to reduce the construction land. The high-rise building foundation pits used at this stage generally belong to the more dangerous sub-projects exceeding a certain scale. Because the foundation pit construction is affected by the surrounding existing buildings, it is impossible to realize the sloping excavation construction. Therefore, in order to ensure the safety of the foundation pit excavation and foundation construction stage, deep foundation pit construction is generally protected by foundation pit support. The foundation pit support is to ensure the safety of the underground engineering construction and the roads around the foundation pit and the existing buildings. Through scientific and reasonable design, the support system is set around the side walls of the foundation pit, thereby improving the excavation construction of the foundation pit and the overall building construction. security.

Analysis of foundation treatment technology in high-rise building construction
Today, with the formation of large cities and megacities, the net inflow of urban population has increased significantly, and the plane and three-dimensional range of urban buildings has increased. As the most important development mode of urban space development, high-rise buildings have greatly alleviated the problems of urban land shortage and environmental congestion. In the construction of high-rise buildings, the foundation is an important foundation and premise, and it is also the guarantee for the safe construction and use of buildings. Therefore, it is necessary to scientifically treat the foundation of high-rise building projects and effectively improve the construction quality of high-rise building projects. Avoid unnecessary safety hazards in construction and subsequent use, which will affect social harmony and stability.
