Bentonite waterproof blanket of geotechnical materials used in the repair and seepage prevention work of tailings pond
With the gradual strengthening of the national awareness of environmental protection, the construction of tailings landfill has put forward higher requirements. The traditional anti-seepage method, cement concrete, stone stacking, waterproof coating and so on are no longer applicable, accompanied by the rapid development of geosynthetic materials, and widely used in various fields. Geosynthetics are divided into four categories: geotextile, geomembrane, geotechnical composite materials and geotechnical special materials, among which new HDPE geomembrane, geotextile, composite geomembrane, bentonite waterproof blanket, composite drainage network and other geotechnical materials are also more and more common in the mine tailings pond environment. They play an important role in the tailings repair and seepage prevention work with their excellent seepage prevention performance, construction convenience and excellent durability.
Today we share the geotechnical material ——— Bentonite waterproof blanket。
Bentonite waterproof blanket is a new kind of new geosynthetic material, is made of high expansion of sodium bentonite filling in special composite geotextile and non-woven fabric, with acupuncture into bentonite seepage pad can form many small fiber space, is bentonite particles cannot flow like one direction, in water form uniform high density rubber waterproof layer, effectively prevent water leakage. High performance and price ratio, the use is very wide. The product range can reach 6 meters, greatly improving the construction efficiency. Scope of application application conditions: applicable to municipal (landfill), water conservancy, artificial lake building underground waterproof, seepage preverntion engineering.
