Abstract

The invention relates to a cast-in-situ bored pile foundation pit supporting structure. The cast-in-situ bored pile foundation pit supporting structure comprises a bottom plate, a supporting plate, an insertion rod and a supporting rod connected between the bottom plate and the supporting plate, an expansion piece is arranged at one end of the insertion rod, the expansion piece is located in a pile hole of a cast-in-situ pile, and the other end of the insertion rod is connected with the supporting plate through a connecting piece. According to the cast-in-situ bored pile foundation pit supporting structure, by arranging the insertion rod and the expansion piece, connection between the supporting plate and the cast-in-place pile can be established, so that the cast-in-place pile and the supporting plate can jointly bear lateral soil pressure, and the lateral soil pressure resisting capacity of the foundation pit supporting structure is improved in a disguised mode.

Description

technical field [0001] The present application relates to the field of construction support structures, in particular to a support structure for bored pile foundation pits. Background technique [0002] With the continuous development of urban modernization, the requirements for the development and construction of urban space are becoming increasingly urgent, and there are more and more constructions of various underground projects. Large-scale underground projects have higher and higher requirements for deep foundation pit engineering. During the excavation of the foundation pit, the surrounding soil will inevitably be deformed, which will affect the underground pipelines of the surrounding buildings, and seriously endanger the normal use and safety of the underground pipelines. In order to avoid this situation, a foundation pit support structure will be set up in the foundation pit design and excavation construction to stabilize the safety of the foundation pit. [0003]...
