Detachable soil nail wall panel structure

Abstract

The invention discloses a detachable soil nail wall panel structure. The detachable soil nail wall panel structure comprises a template and PVC casing pipes. A layer of steel bar mesh is arranged on the surface of the template. Longitudinal circular holes are symmetrically formed in the front end face and the rear end face of the template left and right. Transverse circular holes are formed in the centers of the left end face and the right end face of the template. A soil nail installing circular hole is formed in the center of the upper surface of the template. The PVC casing pipes are arranged in the longitudinal circular holes, the transverse circular holes and the soil nail installing circular hole. Steel bars are movably arranged in the longitudinal circular holes and the transverse circular holes through the PVC casing pipes. According to the detachable soil nail wall panel structure, adjacent templates are connected by inserting the steel bars into the PVC casing pipes, a soil nail is arranged in the soil nail installing circular hole in the center of the surface of the template, and after the template completes the function, the template can be dismounted; and the detachable soil nail wall panel structure has the beneficial effects that construction is firm, construction materials cannot be wasted, the construction materials cannot pollute the underground, and a support panel can be repeatedly used.

Description

technical field [0001] The invention relates to the technical field of soil nailing walls, in particular to a detachable soil nailing wall panel structure. Background technique [0002] Soil nail walls are widely used in foundation pit support projects. Foundation pit projects are temporary projects, and the service life is generally not more than two years. Some soil nail wall support structures are composed of soil nail reinforcement densely distributed in the soil of the side wall of the foundation pit and a reinforced concrete surface layer adhered to the surface of the side wall of the foundation pit. The specific construction of this soil nail wall support structure First excavate the foundation pit to the depth below the soil nail position, use Luoyang shovel or machine to form a hole, put in the reinforced soil nail, inject grout into the soil nail hole, hang the steel mesh, spray the concrete surface layer, and wait until the surface layer concrete reaches the desig...

[0002] Soil nail walls are widely used in foundation pit support projects. Foundation pit projects are temporary projects, and the service life is generally not more than two years. Some soil nail wall support structures are composed of soil nail reinforcement densely distributed in the soil of the side wall of the foundation pit and a reinforced concrete surface layer adhered to the surface of the side wall of the foundation pit. The specific construction of this soil nail wall support structure First excavate the foundation pit to the depth below the soil nail position, use Luoyang shovel or machine to form a hole, put in the reinforced soil nail, inject grout into the soil nail hole, hang the steel mesh, spray the concrete surface layer, and wait until the surface layer concrete reaches the design strength Then build the next soil nail, and the connection between the soil nail and the surface layer steel bar is welded. This connection method often appears in the construction site. The connection with the soil nails fails. After the end of the service period, the soil nails and the surface layer will be permanently buried underground, resulting in a large waste of resources, encroaching and affecting the subsequent use of the underground space. In addition, the surface layer concrete spray anchor construction Will produce a lot of pollution, not conducive to environmental protection
