1. Roll it by hand; the cloth surface should be flat and the deformation allowance should be left.
2. The installation of filament or short-staple geotextiles is usually done by lap joints, stitching and welding. The width of the stitching and welding is generally 0.1 m or more, and the overlap width is generally 0.2 M or more. Geotextiles that may be exposed for a long time should be welded or stitched.
3. During the construction, the geotextile on the geomembrane is naturally lapped, and the geotextile of the geomembrane upper layer is seamed or hot-air welded. Hot air welding is the first method of joining the filament geotextiles, that is, the connection of the two pieces of cloth with a hot air gun is instantaneously heated at a high temperature to partially melt the state, and immediately use a certain external force to firmly bond them together. .
In the case of wet (rainy and snowy) weather, the hot-adhesive connection is not possible. The geotextile should adopt another method, a suture connection method, that is, a double-threaded suture connection with a special sewing machine, and a chemical-resistant ultraviolet suture is used.
