Detachable soil nailing wall construction method and soil nailing wall structure

Abstract

The invention provides a detachable soil nailing wall construction method and a soil nailing wall structure, and relates to the technical field of construction, and the technical problem of inconvenient construction of a soil nailing wall in the prior art is solved. The detachable soil nailing wall construction method includes the steps that a working face is excavated to form a side slope, and panels are laid on the side slope; the panel laying includes the processes that soil nail holes are formed for grouting, the soil nail holes are formed in the side slope, soil nails are inserted into the soil nail holes and part of each soil nail exposes outside corresponding soil nail hole, and then slurry is injected into the soil nail holes to fix the soil nails; a plurality of panels are installed, adjacent panels are connected with each other, and the panels include overturning panels and main panels, the overturning panels are arranged in the first row of the side slope, the main panels are arranged on the lower sides of the overturning panels, and the soil nails penetrate out from the adjacent panels; depression bars are installed, the depression bars are arranged at the junction of the panels, and the depression bars are fixed to the soil nails through connecting pieces, and the depression bars are attached to the panels. The detachable soil nailing wall construction method and the soil nailing wall structure are used for the construction of foundation pit soil protection structures, and the protection structure is enabled to be assembled and disassembled conveniently and reused.

Description

technical field [0001] The invention relates to the technical field related to building construction, in particular to a detachable soil nail wall construction method and a soil nail wall structure. Background technique [0002] As a flexible retaining structure, the soil nail wall has been widely used in slope protection and foundation pit excavation, and plays an increasingly important role in water conservancy, construction and other industries. The existing soil nail wall is generally composed of soil nails 1. Steel mesh and concrete. During construction, soil nails are first set in the soil on the side wall of the foundation pit, then the steel mesh is hung and fixed on the soil nails, and then concrete is sprayed onto the steel mesh to form a soil nail wall. [0003] It has the following disadvantages: [0004] 1. There is no reliable measure to control the quality of the strength of the panel formed by sprayed concrete, and generally it cannot reach the design streng...
