Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support, in particular to a foundation pit support structure. Background Art

[0002] Foundation pit support engineering refers to the engineering measures taken during foundation pit excavation to ensure the stability of the pit wall, protect the safety of the main underground project during construction, and protect the surrounding environment from damage. Installing foundation pit support structures inside the foundation pit to support the inner wall of the foundation pit is a conventional technical means;

[0003] For foundation pits with small depth, when the slope width of some sections is not enough, simple support methods such as short column diaphragm support, temporary retaining wall support, and inclined column support can be used. The steps of inclined column support are to first drive piles along the edge of the foundation pit, support retaining boards on the inner side of the piles and support them with inclined braces, fill the inner side of the retaining board and tamp it to complete the simple foundation pit support;

[0004] However, the piles need to be driven into the foundation pit under the action of external force, and the piles need to be driven frequently and repeatedly, which is time-consuming and labor-intensive. In addition, the piles will tilt in the process of going deeper into the foundation pit, resulting in a gap between the piles and the retaining plate. The piles and the retaining plate and the diagonal braces are not strong enough. When the diagonal column support is in use, there is a problem that the diagonal column support structure cannot be assembled firmly and conveniently. Utility Model Content
