Embodiment

[0029] Such as Figure 1-4 As shown, a polygonal foundation pit support structure includes a support plate 1, and the support plate 1 includes two arc-shaped plates 8 corresponding to each other. The two arc-shaped plates 8 are fixedly connected to each other, and the arc shape can disperse the force. Thereby the range of stress is relatively large, between the two arc-shaped plates 8 is filled with foam material 9, the foam material 9 can absorb the impact force, and one side of the support plate 1 is vertically and symmetrically provided with two first limit blocks 2, two Each of the first limiting blocks 2 is fixedly connected with the supporting plate 1, and the side of the supporting plate 1 away from the first limiting block 2 is provided with a limiting mechanism 3 for limiting two first limiting blocks 2.

[0030] The limit mechanism 3 includes two second limit blocks 10 fixedly connected with the support plate 1, the two second limit blocks 10 correspond to the two fi...

Abstract

The invention belongs to the technical field of foundation pit supporting, in particular to a polygonal foundation pit supporting structure and a construction method. The polygonal foundation pit supporting structure comprises a supporting plate, two first limit blocks are vertically and symmetrically arranged on one side of the supporting plate and fixedly connected with the supporting plate, limit mechanisms for limiting the two first limit blocks are arranged on one side, far away from the limit mechanisms, of the supporting plate, a bottom plate is horizontally arranged on the lower side of the supporting plate, one end of the bottom plate is fixedly connected with the lower end of the supporting plate, the reinforcing mechanism for reinforcing the supporting plate is arranged on the bottom plate, a plurality of fixed blocks are vertically arranged on one side, far wary from the bottom plate, of the supporting plate and fixedly connected with the supporting plate, openings are vertically formed in the fixed blocks, and matched limit columns are arranged in the openings. The supporting structure has the advantages that the supporting structure is reasonable, a stable function isachieved through a plurality of structures, the integrated structure is more stable through the interaction principle of forces, and the ranges of the pressure and the impact force borne by a supporting plate structure are wider.

Description

technical field [0001] The invention belongs to the technical field of foundation pit support, and in particular relates to a polygonal foundation pit support structure and a construction method. Background technique [0002] The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures adopted for the side wall of the foundation pit and the surrounding environment. 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] The existing foundation pit suppo...
