Safety supporting structure for civil engineering foundation pit supporting

Abstract

The invention relates to the technical field of foundation pit supporting, and particularly relates to a safety supporting structure for civil engineering foundation pit supporting. The safety supporting structure comprises a plurality of supporting plates, wherein upper channel steel extending towards one side of a slope body is fixedly arranged at the upper ends of the supporting plates, lower channel steel extending towards the side away from the slope body is fixedly arranged at the lower ends of the supporting plates, openings of the upper channel steel and the lower channel steel are upward, and drainage grooves used for drainage are formed in the upper ends and the lower ends of the supporting plates; and vertically-arranged reinforcing ribs are arranged in the middles of the left sides of the supporting plates, and first holes are formed in the reinforcing ribs. According to the safety supporting structure, the supporting plates, the reinforcing ribs and steel wire ropes are arranged so that the overall structural stability of the supporting plates can be improved, the vibration energy can be consumed, the damping effect can be achieved, and therefore the situation that residual deformation of prestressed anchor rods is caused due to position deviation of the supporting plates can be avoided, the constraint of the prestressed anchor rods on the slope body can be guaranteed, and the risk of instability and collapse of the slope body can be reduced.

Description

technical field [0001] The invention relates to the technical field of foundation pit support, in particular to a safety support structure for civil engineering foundation pit support. Background technique [0002] With more and more high-rise buildings, the depth of the foundation pit is also increasing, and the excavated underground space can be used as garages, storage, shopping malls, civil air defense projects, etc. After the excavation of the foundation pit of the building, it is necessary to make a support structure around it to prevent local or large-scale landslides. The traditional support structure is a soil-nailed wall structure, which has the advantages of low production cost and fast production, but now When the foundation pit is very deep, the one-layer soil nail wall structure can no longer guarantee to prevent partial or large-scale collapse of the foundation pit. [0003] The existing Chinese patent whose authorization notification number can be referred t...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem in the prior art that the residual deformation of the prestressed anchor rod is likely to occur when the external vibration occurs, resulting in the weakening of the restraint of the support structure on the slope, which in turn leads to the instability and collapse of the slope. A safety support structure for civil engineering foundation pit support proposed by the invention
