Description

Technical Field

[0001] The present application relates to the technical field of foundation pit support, and in particular to a foundation pit support structure that is easy to assemble and fix. Background Art

[0002] The foundation pit refers to the space below the ground excavated for the construction of the building foundation and basement. The foundation pit will cause deformation of the surrounding soil during the excavation process, which will affect the surrounding buildings and underground pipelines. In serious cases, it will endanger the normal use or the personal safety of the staff. In order to ensure the smooth construction of the foundation pit and the safety of the surrounding buildings, a support structure is usually set between the foundation pit and the side walls of the foundation pit. The function of the foundation pit support structure is to prevent groundwater and soil outside the foundation pit from flowing into the foundation pit. The current foundation pit support structure cannot be assembled into an overall support suitable for the current size of the foundation pit according to the size of the foundation pit. It supports the foundation pit alone and resists the deformation of the soil. After a long time, it is easy to be unable to withstand the deformation of the soil and cause the foundation pit support to deform, thereby reducing the protection ability of the slope. Therefore, a foundation pit support structure that is easy to assemble and fix is ​​needed.

[0003] A Chinese utility model patent with publication number CN214460449U discloses a foundation pit support structure, which places a base plate at the bottom of the foundation pit, rotates the guard plate to make the guard plate and the side wall of the foundation pit fit together, and limits the rotation of the rotating shaft through a limit assembly to fix the angle between the guard plate and the base plate, maintain the fit between the guard plate and the side wall of the foundation pit, improve the fit between the guard plate and the side wall of the foundation pit, and improve the support strength of the guard plate to the foundation pit.

[0004] However, in the above patent, the overall support suitable for the current size of the foundation pit can be assembled according to the size of the foundation pit. The foundation pit is supported only by individual parts. If the deformation of the soil is resisted for a long time, the foundation pit support will be deformed due to its low resistance, which reduces the ability to protect the slope.
