Background

With the increasing shortage of urban land, the construction of basements is also great, and the foundation pit support becomes an important link of the construction of underground structures. At present, support piles are widely adopted in foundation pit construction to serve as foundation pit support structures, so that deformation of the surrounding environment of a foundation pit and collapse of the foundation pit are prevented, and smooth proceeding of engineering construction is guaranteed.

The existing supporting structure has poor integral rigidity, and because the surrounding environment or load change of a foundation pit, ground drainage, rainfall and other influences easily cause the stress of the supporting structure to be increased or the effectiveness of a supporting system to be weakened, the deformation of the foundation pit supporting system is too large, even the foundation pit supporting system is failed, and the construction safety is seriously threatened. Some foundation trench excavations of about five meters are favored by the construction community for supporting vertical excavation by using small-tooth-opening steel sheet piles. According to the calculation requirements of 'construction standards of foundation engineering of building foundation', steel supports need to be arranged and need to be supported in two directions. Due to the limitation of site conditions, emergency and reinforcement measures such as excavation, unloading, addition and the like after the structure cannot be adopted.
