Embodiment 1

[0035] Embodiment 1: Composite hydrophobic and waterproof membrane:

[0036] Such as figure 1 with figure 2 As shown, it includes a waterproof board layer 1, and a second non-woven fabric layer 2, a drainage layer 3 and a first non-woven fabric layer 4 arranged in sequence on the waterproof board layer, wherein the adjacent two layers are passed through thermal fusion or It is connected by glue, and at least one side of the drainage layer contains a concave well-shaped drainage groove, and the well-shaped drainage groove faces the tunnel primary lining. When both sides of the drainage layer contain well-shaped drainage grooves, they face the direction of the tunnel lining and the waterproof slab layer respectively. The first non-woven layer is in contact with the concrete surface 5 of the tunnel.

[0037] The drainage layer is made of nylon, which has superior aging resistance and compressive strength compared with the polypropylene material of conventional drainage boards...

Abstract

The invention discloses a composite hydrophobic and waterproof coiled material which comprises a waterproof plate layer; a first non-woven fabric layer, a drainage layer and a second non-woven fabriclayer are sequentially arranged on the waterproof plate layer, every two adjacent layers are connected in a hot melting or gluing mode, and the drainage layer comprises sunken #-shaped drainage grooves. According to the structure, the drainage plate with the transverse V-shaped drainage grooves and the longitudinal V-shaped drainage grooves and the waterproof plate are combined into a whole in a hot melting or gluing mode; waterproof effect is achieved in tunnels or other underground engineering, and a part of tunnel seepage water can be dredged and removed along the V-shaped grooves in advance before reaching the waterproof plate, so that the pressure-bearing burden of the waterproof plate is reduced, and the service life of the whole waterproof plate is prolonged; the procedure of pre-laying a drainage pipeline before construction is omitted, so that the construction speed is increased, the construction efficiency is improved, and the cost is reduced; compared with an existing drainage plate, the composite hydrophobic and waterproof coiled material has the advantages that the water delivery flux is larger, longitudinal drainage and transverse drainage are communicated, and the problems of water seepage and sedimentation are avoided.

Description

technical field [0001] The invention belongs to the technical field of tunnel waterproofing and drainage, and in particular is a water-repellent coiled material. Background technique [0002] Aquifers will inevitably be encountered during tunnel excavation and construction. After the initial concrete lining of the tunnel is laid, water seepage may also occur, which not only affects the subsequent construction operations of workers and equipment, but also affects the construction. quality. [0003] The published patent document "Anti-leakage structure and construction method of wellbore with large cross-section through aquifer" (application number: CN201310317134.1) discloses the use of multi-layer support mechanism, and a water-resistant layer is set between adjacent supports , so as to solve the problem of insufficient wellbore anti-leakage measures. However, the use of multi-layer support brackets is also a construction operation, which not only affects the space and safe...
