Foundation pit supporting structure

Abstract

The invention provides a foundation pit supporting structure. The foundation pit supporting structure is used for supporting a foundation pit. The foundation pit supporting structure comprises a plurality of bottom fixing parts, connecting parts and a plurality of supporting groups. Each support grouping comprises two telescopic parts and a supporting rod. One ends of the every two telescopic parts are separately fixed to two ends of each supporting rod, the other ends of the every two telescopic parts are separately fixed on the two opposite side walls of the foundation pit, and the telescopic parts can be stretched out and drawn back; the supporting groups are arranged at intervals in the first direction, and the supporting groups are connected through the connecting parts; and the bottom fixing parts are fixed to the bottom of the foundation pit, each supporting group is erected on at least one bottom fixing part, the first direction is parallel to the bottom surface of the foundation pit and perpendicular to the extension direction of the supporting groups. The foundation pit supporting structure can effectively solve the problem that a foundation pit supporting structure in the prior art cannot be applied to a large-span foundation pit.

Description

technical field

[0001] The invention relates to the construction field of foundation pit support engineering, in particular to a foundation pit support structure. Background technique

[0002] Foundation pit support refers to the support, reinforcement and protection measures adopted for the side wall of the foundation pit and the surrounding environment in order to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. Whether it is a high-rise building or a deep foundation pit project for subway construction, since most of them are excavated in cities, there are usually various structures such as traffic arteries, existing buildings or pipelines around the foundation pit. It is necessary to protect the surrounding structures of the foundation pit. Safe use makes foundation pit support a very important part of foundation pit excavation. At present, foundation pit support systems in soft soil areas include concrete...
