Abstract

The invention provides a foundation pit supporting structure, and relates to the technical field of foundation pit construction. The foundation pit supporting structure comprises a plurality of layers of supporting assemblies arranged at intervals along the depth of a foundation pit and transverse supporting assemblies mounted at the top of the foundation pit; each layer of supporting assembly comprises a protection mechanism attached to the inner wall of the foundation pit and an inner pile arranged in the inner wall of the periphery of the foundation pit, the inner piles and the protection mechanisms are fixed through connecting assemblies, and the inner piles comprise shells and fillers in the shells; and an embedded groove is formed in the side wall of the foundation pit in the inclined direction, and a top end opening of the embedded groove is formed in the side wall of the foundation pit. According to the foundation pit supporting structure, a supporting frame does not need to be arranged at the bottom of the foundation pit, the internal space of the foundation pit is saved, foundation pit construction is facilitated, the construction efficiency of the foundation pit is improved, the protection mechanisms and the inner piles can be effectively fixed, and the effect of stabilizing the foundation pit is achieved; and meanwhile, the stability of the supporting structure is further improved through the transverse supporting assemblies.

Description

technical field [0001] The present application relates to the technical field of foundation pit construction, in particular, to a foundation pit support structure and a construction method thereof. Background technique [0002] At present, with the development of urban construction, high-rise buildings are gradually increasing, and urban buildings are becoming more and more dense. Due to the requirements of the use function and the development of underground space, high-rise buildings are generally designed with a basement with a large plane size and depth. The development of underground space involves the safety of deep building foundation pits, which is especially important for densely built areas located on soft soil foundations. [0003] Therefore, the foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. Existing foundation pit support structures include ground connection walls, ...
