A soil nailing wall support system based on prefabricated recyclable technology

Abstract

The invention relates to a soil nail wall support system based on an assembled recyclable process in the field of civil engineering, which includes multiple soil nails, multiple nodes, multiple keels and multiple panels, and multiple nodes are laid on a horizontal straight line. On the slope, multiple nodes are spaced at a set distance, and the nodes are covered layer by layer on the slope. One end of the soil nail is inserted into the slope through the hole of the node, and the adjacent ones in the same layer The two nodes are connected through the keel, and the multiple panels are fixed between two adjacent layers. The structure of the support system in the present invention has high stability, and all support structural components can be factory-processed and assembled for construction; the support materials can be recycled and reused, which can save resources; save construction costs, and in addition The support material will not stay in the ground.

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
