What is the function of the waterproof board?

Many owners do not understand the thickness requirements of the waterproof plate. In order to prevent people from buying fake and inferior products, we summarize the knowledge about waterproof board. Let's see. Waterproof plate is mainly used to prevent liquid leakage and gas volatilization. Waterproof plate is mainly used for seepage prevention and isolation of rock engineering, but also plays a role of reinforcement and protection.

Waterproof plate is mainly used for earthwork dam, rockfill dam, masonry dam, concrete dam, tailings dam, sewage reservoir dam, channel, liquid storage tank and other engineering seepage prevention, subway, basement, tunnel seepage prevention lining, highway, railway foundation seepage prevention, as well as the use of filament geotextile and bentonite waterproof blanket geotextile materials in household waste landfill.

The main function of the waterproof plate is to prevent liquid leakage and gas volatilization. The role of waterproof plate in rock engineering is mainly seepage prevention and isolation, but also plays the role of reinforcement and protection. Mainly used in earthwork dam, rockfill dam, masonry dam, concrete dam, tailings dam, sewage reservoir dam, channel, liquid storage tank and other engineering seepage prevention, subway, basement, tunnel seepage prevention lining, highway, railway foundation seepage prevention, as well as in household waste landfill using filament geotextile and bentonite waterproof blanket geotextile materials.

Waterproof board construction technology:

1. Preparation before laying:

1. Foundation treatment.

2. Sand or clay layer with small particle size should be laid on the surface in contact with the film as a protective layer, and the covering thickness of the protective layer should not be less than 30M.

2. Laying method:

1. Lay in a certain direction, not too tight. A certain amount of expansion should be reserved to adapt to the deformation of the matrix.

2. When laying the waterproof plate, the orientation of each unit should be adjusted to facilitate the welding of the two units.

3. After the waterproof board is laid, the sandbag should be pressed to prevent the influence of wind sand on the next edge welding.

3, waterproof plate welding:

1. Joint treatment is the key process of construction. Generally, the hot welding method is used. The surface of the PE film is heated to melt, and then it is melted into a single layer by pressure.

2. Paved waterproof board, edge joints should be free of oil, water, dust, etc.

3. Before welding, the two PE films at the joint should be adjusted to overlap a certain width. The lap width is generally 6-8M, flat and wrinkle-free.
