Problems solved by technology

Welding is used to connect the soil nails to the steel bars on the surface layer. This connection method often causes insecure connections at the construction site, resulting in some slope instability not because the soil nails are pulled out but because of the failure of the connection between the surface layer and the soil nails.
After the end of the use period, the soil nails and the surface layer will be permanently buried underground, resulting in a large waste of resources, encroaching on and affecting the subsequent use of underground space
In addition, the sprayed anchor construction of surface concrete will produce a lot of pollution, which is not conducive to environmental protection

Embodiment Construction

[0025] Such as Figure 1-2 As shown, a reusable composite material soil nail wall support panel, the support panel includes a plate-shaped main body, and the edge of the plate-shaped main body is provided with an assembled connection part for connecting two adjacent support panels 3. The plate-shaped main body is provided with a soil nail hole 1 and a drain hole 4 penetrating through the main body. The soil nail hole 1 is located at the center of the plate-shaped main body, and the drain hole 4 is located between the assembled connection part 3 and the soil nail hole 1 . In order to increase the overall strength of the support panel, a reinforcing rib 6 is provided inside the plate-shaped main body. The reinforcing rib 6 is made of metal material and has a mesh structure, and its size is slightly smaller than that of the main body. Because the force around the soil nail hole may be too large, in order to improve the service life of the support panel and prevent the damage aro...

Abstract

The invention discloses a reusable composite-material soil nailing wall supporting face plate and a construction method thereof and relates to the technical field of anchoring structural parts or wall protection devices. The supporting face plate comprises a plate body, splicing connection portions for connecting two adjacent supporting face plates are arranged at the edges of the plate body, and soil nail holes and water leakage holes penetrating the body are formed in the plate body. The supporting face plate is used for soil nailing wall construction and has the advantages of being firm in construction, capable of preventing wasting of construction materials and preventing construction materials from polluting the underground and reusable.

Description

technical field [0001] The invention relates to the technical field of devices for anchoring structural parts or retaining walls, in particular to a reusable composite material soil nail wall support panel and a construction method thereof. Background technique [0002] Soil nail walls are widely used in foundation pit support projects, and foundation pit projects are temporary projects with a short service life (generally no more than two years). After the construction of the underground structure of the building is completed, the service period of the soil nail wall will gradually end with the backfilling of the foundation pit. The existing soil nail wall support structure is composed of soil nails (steel bars) 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 kind of soil nail wall support structure is to first exc...
