Foundation pit supporting structure

Abstract

The invention provides a foundation pit supporting structure which comprises stabilizing piles stand into the pit bottom of a foundation pit in an inserted mode, supporting piles inserted into the pitbottom of the foundation pit along the inner wall of the foundation pit and inclined supporting rods. The stabilizing piles and the supporting piles are fixedly connected with wall protection platesthrough bolts, and the two ends of the inclined supporting rods are supported between the corresponding wall protection plates on the stabilizing piles and the corresponding wall protection plates onthe supporting piles respectively. By adopting the technical scheme, baffles play a first role in protecting the inner wall of the foundation pit, the inclined supporting rods, the supporting piles and the stabilizing piles play a second role in protecting the inner wall of the foundation pit, transverse supporting rods and the oppositely-arranged supporting piles play a third role in protecting the inner wall of the foundation pit, the inclined supporting plates and the supporting piles play a fourth role in protecting the inner wall of the foundation pit, under multi-protective effects, soilaround the foundation pit is effectively prevented from collapsing, the protection effect is improved, potential safety hazards are reduced, all the supporting parts are steel structural parts, machining and manufacturing are convenient, repeated use is achieved, assembling and disassembling are convenient, and the supporting structure is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a foundation pit support structure. Background technique [0002] With the continuous development of the construction industry, there are more and more high-rise and super high-rise buildings. The stability of these high-rise buildings depends on the foundation. Before the foundation is built, the foundation pit needs to be excavated first. The soil around the foundation pit collapses, and timely support is required. In the prior art, there are various support structures for foundation pits, but most of them are temporary supports. After one use, the corresponding support devices will be discarded, resulting in Waste of resources, and the common way in the technology is to use shotcrete to temporarily support the inner wall of the foundation pit. This support method uses a large amount of concrete, and the concrete is easy to crack and fall off in pieces. The sup...

[0002] With the continuous development of the construction industry, there are more and more high-rise and super high-rise buildings. The stability of these high-rise buildings depends on the foundation. Before the foundation is built, the foundation pit needs to be excavated first. The soil around the foundation pit collapses and needs to be supported in time. In the existing technology, there are various types of foundation pit support structures, but most of them are temporary supports. After one use, the corresponding support devices will be discarded, resulting in Waste of resources, and the common way in the technology is to use shotcrete to temporarily support the inner wall of the foundation pit. This support method uses a large amount of concrete, and the concrete is easy to crack and fall off in pieces. The support effect is not good, and The stability is poor, and there is a big security risk
