Study On Deep Foundation Pit Supporting Scheme And The Construction Organization Design Of Wansheng Building

Because of the rapid development of urban high-rise building, the underground parking lot, high-rise building foundation air-defense buried depth, various needs more and more in the pit depth. High-rise building of deep excavation engineering, are generally in the city of foundation pit excavation, around there are usually transport arteries, has built a building or underground pipeline, etc. Various kinds of structures, this involves trying to protect its surrounding structures or the safety of the building. General foundation pit supporting are mostly temporary structure, the investment is too big easy cause waste, but supporting structure not safe and would cause engineering accident. Therefore, how to safety, reasonably choosing appropriate supporting structure, and according to the characteristics of foundation pit engineering scientific design is deep foundation pit bracing engineering to solve main problems.Paper analyzes systematically the development trend of excavation engineering, this paper expounds the basic theory and foundation pit engineering construction group design of the general principle.In shangluo wellsun building for foundation pit engineering projects, according to engineering practice sure foundation pit supporting scheme for soil nailing support and pile, then to anchor bracing for the support scheme design parameter selection and supporting structure stability checking. In order to guarantee the foundation pit engineering smoothly and foundation pit, made the safety of scientific and reasonable construction group design, planning construction schedule, and carries on the management of foundation pit construction process monitoring method, using the construction site civilized construction measures, attention and quality guarantee system. Ensure the wellsun building foundation pit engineering, could provide the reference for the similar engineering projects.
