Soil nailing wall supporting system based on assembly type recoverable process

Abstract

The invention relates to a soil nailing wall supporting system based on the assembly type recoverable process in the field of civil engineering. The system comprises a plurality of soil nails, a plurality of joints, a plurality of keels and a plurality of panels. The joints are laid on the slope face as a horizontal straight line and spaced by a set distance. The joints cover the slope face one layer by one layer. One ends of the soil nails penetrate through holes of the joints and are inserted into the slope face. Every two adjacent joints in the same layer are connected through the keels. The panels are fixed between the two adjacent layers. The supporting system is high in structural stability, and all the supporting structural members can be machined in factories, and can be assembled for construction; supporting materials can be recovered and reutilized, and in this way, resources can be saved; the construction cost is saved, and in addition, the supporting materials will not be left underground.

Description

technical field [0001] The invention relates to a soil nail wall support system based on an assembled recyclable process. Background technique [0002] Soil nail wall support is a commonly used support technology in foundation pit and slope engineering. It consists of soil nails, soil between nails, and surface layers to form a force-bearing structure. The traditional method is to construct soil nails first and then hang net spraying on the surface. At present, the method of soil nailing is generally to put steel bars into the holes, and then inject grout. The body of the soil nails generally adopts steel bars. Another method is to directly drive steel pipes into the soil nails as soil nails. At present, the surface layer method is basically to bind the steel mesh on the slope surface, and then spray the concrete. The result of this is that the materials after the backfill of the foundation pit cannot be recycled, and they are directly buried underground, which not only cau...

Problems solved by technology

The result of this is that the materials after the backfill of the foundation pit cannot be recycled, and they are directly buried underground, which not only causes waste of materials, but also pollutes the geological environment. At the same time, the constructed soil nails may become an obstacle to the construction of new underground projects in the surrounding area, affecting the subsequent underground space. to develop
