Foundation pit supporting structure and construction method thereof

Abstract

The invention relates to a foundation pit supporting structure and a construction method thereof. The foundation pit supporting structure comprises a B-class cast-in-place pile, a first reinforced concrete support, a second reinforced concrete support, a bottom plate, a cast-in-place bored pile and a latticed column. The B-class cast-in-place pile is vertically arranged in a foundation pit, the first reinforced concrete support and the second reinforced concrete support are horizontally arranged and sequentially connected with the B-class cast-in-place pile from top to bottom, the cast-in-place bored pile is vertically arranged, the top end of the cast-in-place bored pile is connected with the bottom plate, the latticed column is fixedly arranged on the cast-in-place bored pile, and an inclined throwing support is arranged between the bottom plate and the first reinforced concrete support. According to the foundation pit supporting structure, by arranging the inclined throwing support,the strength and stability of the whole supporting structure can be effectively improved, and it is guaranteed that no soil collapse phenomenon occurs; the latticed column can play a role in supporting the first reinforced concrete support and the second reinforced concrete support, so that the foundation pit is more stable; and the inclined throwing support is fixedly connected with the bottom plate and the pond wall of a storage pond through reinforced concrete brackets, so that the foundation pit is more stable.

Description

technical field [0001] The invention belongs to the technical field of foundation pits, and in particular relates to a foundation pit supporting structure and a construction method thereof. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. For foundation pits with relatively low depth, slope excavation can be used to excavate foundation pits, but for deep foundation pits, foundation pit support structures must be used to prevent the soil on the side walls of the foundation pit from collapsing, and at the same time ensure that the foundation pit is in The safety of construction personnel during the entire construction process. In the prior art, a concrete support structure is poured inside the foundation pit to ensure that the foundation pit will not collapse. However, the existing support structure for the foundation pit is not strong enough, and collapse will o...
