Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a foundation pit supporting structure for preventing landslides. Background Art

[0002] Foundation pit support is a measure of support, reinforcement and protection for 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. The foundation pit will inevitably cause deformation of the surrounding soil during the excavation process, and will affect the underground pipelines of the surrounding buildings, which will 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 during the foundation pit design and excavation construction to stabilize the safety of the foundation pit.

[0003] The existing Chinese utility model patent with reference announcement number CN208917848U discloses a foundation pit support structure. In the field of foundation pit support, the key points of its technical solution are that it includes a support plate that fits with the side wall of the foundation pit, support piles that support the support plate and are wedged into the bottom of the foundation pit, and a connecting assembly for connecting the support plate and the support piles together; a support plate is provided with a plurality of support piles for supporting the support plate and a plurality of connecting assemblies for connecting the support plate and the plurality of support piles together; the support piles are prefabricated piles and are vertically wedged into the bottom of the foundation pit. The utility model solves the problem that when the bottom of the foundation pit is not reinforced with concrete, the support force of the foundation pit support structure on the side wall of the foundation pit is relatively small, and when the pressure on the side wall of the foundation pit is large, the foundation pit support structure may not have a good supporting effect, thereby making the foundation pit more stable.

[0004] Based on the search of the above patents and combined with the equipment in the prior art, it was found that when shielding the side walls of the foundation pit, the traditional support method is manual welding, and the support is assembled and shielded, resulting in low efficiency of overall installation and disassembly, affecting subsequent use. When the support is used, the support cannot be adjusted according to the terrain and the shape of the wall, resulting in poor overall support effect. The existence of these problems affects the use of the device. Utility Model Content
