Abstract

The invention discloses a production process for a self-exhausting waterproof coiled material of a water conservancy project, relating to the field of a waterproof technology of the water conservancy project. According to the process, rubber powder is taken as a main raw material, organic functional clay is taken as an auxiliary material and a polyester filament woven geofabric is taken as a covering body, wherein the preparation mass ratio of the rubber powder to the organic functional clay is 1 to (0.2-0.3); the self-exhausting waterproof coiled material is prepared by procedures of preparing materials, internally mixing, molding and rolling, covering a film, drawing and coiling. According to the process method, the production cost of the waterproof coiled material is reduced; the waterproof and ventilating performance is guaranteed and the tensile strength of the material is improved; the waterproof coiled material is suitable for the water conservancy project and the problem that a composite geomembrane used by the water conservancy project is swollen is solved; the waterproof coiled material produced by the process is simple and convenient to construct and does not need to be welded so that the construction difficulty is lowered greatly and the construction efficiency and the construction quality are improved.

Description

technical field [0001] The invention relates to the technical field of waterproofing of water conservancy projects, in particular to a production process of self-venting waterproof rolls for water conservancy projects. Background technique [0002] The inflation problem of the composite geomembrane used in water conservancy projects has always been a difficulty that plagues engineering applications. The traditional disposal method generally uses a check valve device. Although the check valve hydraulic project is theoretically feasible, the actual operation is more than satisfactory. A single check valve is about 500 yuan, and the arrangement of check valves in water conservancy projects is generally 3 pieces / 10m, which not only increases the project cost and construction difficulty, but also check valves are easily damaged and difficult to repair; poor lap joints between composite geomembrane materials are also A big problem is that the joints between materials are not good,...
