Soil nailing wall supporting construction method based on assembly type recoverable process

Abstract

The invention relates to a soil nailing wall supporting construction method based on the assembly type recoverable process in the field of civil engineering. A supporting structure is composed of recoverable soil nails and assembly type prefabricated panels. A plurality of joints are arranged on the slope face in a multi-straight-line mode. The soil nails are arranged on the joints. Keels are arranged between the adjacent joints. The panels are installed among multiple straight lines. A foundation pit is excavated layer by layer to the pit bottom, and the joints, the soil nails, the keels and the panels are arranged layer by layer to finish construction of assembly type soil nailing supporting; supporting materials are disassembled and recovered; the panels, the keels, the joints and the soil nails are disassembled layer by layer after the foundation pit function is finished, and therefore the supporting materials can be recovered and reutilized. Assembly type construction can be achieved, the supporting materials can be machined in factories, and can be recovered and reutilized, and the purpose of environmental protection is achieved.

Description

technical field [0001] The invention relates to a construction method for soil nailing wall support 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...

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
