Waterproof plate, drainage plate and drainage-proof plate in tunnels and using method thereof

Abstract

The invention belongs to the field of tunnel waterproof and drainage materials andparticularly relates to a waterproof plate, a drainage plate and a drainage-proof plate capable of being attached to aself-adhesive cloth of the tunnels and achieving adhesive type fixing and using method thereof. The waterproof plate, the drainage plate and the drainage-proof plate structurally comprise a waterproof plate body, and the waterproof plate body is provided with an attaching mechanism formed by a hook face, a foundation body, a back gum layer, a first attaching layer and a second attaching layer, wherein the hook face and the back gum layer are correspondingly arranged on the front and rear faces of the foundation body, the first attaching layer is attached on the back gum layer, and the secondattaching layer is combined on the first attaching layer. When in use, the hook face forming the tunnel waterproof plate, drainage plate and the drainage-proof plate is directly attached on the self-adhesive cloth layer which is fixed to the tunnel primary support by fasteners. The waterproof plate, drainage plate and the drainage-proof plate have the characteristics of being simple in structure and easy to fix.

Description

technical field [0001] The invention relates to the field of tunnel waterproof and drainage materials, in particular to a waterproof board, a drainage board, a waterproof and drainage board which can be bonded with a tunnel self-adhesive cloth to realize sticking and fixing, and a method for using the same. Background technique [0002] In the prior art, the waterproof board, drainage board and waterproof drainage board in the tunnel are fixed in the following manner: first, the self-adhesive cloth layer is fixed on the initial support of the tunnel with hot-melt gaskets and nails, and then the waterproof board, drainage board, etc. The plate or anti-drainage plate is hot-melt welded on the hot-melt gasket. This method of laying and hanging has the following disadvantages: 1) Manual hot-melt welding is required at the hot-melt gaskets one by one, and the construction efficiency is low; Leakage is prone to occur at cracks, making it difficult to guarantee the waterproof and ...

Problems solved by technology

This method of laying and hanging has the following disadvantages: 1) Manual hot-melt welding is required at the hot-melt gaskets one by one, and the construction efficiency is low; Leakage is prone to occur at cracks, making it difficult to guarantee the waterproof and drainage effect of waterproof boards, drainage boards or waterproof drainage boards; Waterproof and drainage boards will affect the waterproof and drainage effect; 4) Impact airflow will be generated during the blasting construction of the tunnel face, and the airflow impacting the waterproof board, drainage board or the gap of the waterproof and drainage board will easily cause further damage to the waterproof board, drainage board or waterproof and drainage board. drop
