Description

Technical Field

[0001] The present application relates to the technical field of foundation pit support, and in particular to a uniform cross-section foundation pit support structure. Background Art

[0002] Deep foundation pit support is a measure of support, reinforcement and protection of the side walls of the foundation pit and the surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit.

[0003] At present, in deep foundation pit support structures, most support plates are used to abut against the inner wall of the foundation pit, and the support plates are supported and fixed by supporting structures. However, since the foundation pit ground is often not flat enough, after the support plates are fixed, the cross-sections of their tops are mostly not on the same plane. This leads to the overall support structure of the deep foundation pit being incomplete and unstable, and there are great safety hazards. Therefore, in this project, a uniform cross-section foundation pit support structure is urgently needed to solve this problem. Utility Model Content
