Which is more suitable for the river reclamation using bentonite waterproof blanket and composite geomembrane?
Characteristics of bentonite waterproof blanket1. density: high density diaphragm sodium bentonite formation in the hydraulic condition, the thickness of about 3mm, its permeability is alpha * 10-11m/sec, density 30cm clay thickness equivalent to 100 times, has a strong self water performance.2. permanent waterproof properties: because sodium bentonite series natural inorganic material, even after a long time or the surrounding environment changes, also does not occur, aging or corrosion, therefore durable waterproof performance.3., simple construction, short duration: compared with other waterproof materials, construction is relatively simple, do not need heating and paste. Only with bentonite powder and nails, gaskets and other connections and fixed. The connection of GCL, especially the connection of GCL with pipe or surrounding of building, is easier than geomembrane, and the sealing property of joint is easy to be guaranteed. No special inspection is required after construction, and it is easy to repair if water proof defects are found.
The integration of waterproof materials and objects: sodium bentonite and water reaction, with expansion capability of 13-16 times, even if the concrete structure vibration and settlement, GCL bentonite can repair the concrete surface crack is less than 2mm.
Or use a waterproof waterproof blanket, permanent waterproof. Good compactness. The sodium base bentonite reacts with water with a 13-16 fold expansion capacity, which makes it an integral property of waterproof materials and objects. Green environmental protection.
Bentonite waterproof blanket is generally used in artificial lake seepage, artificial wetland, artificial lake seepage, seepage Golf basement anti-seepage need coating of bentonite waterproof blanket, water channel engineering seepage control, municipal landfill bottom seepage control needs to be in place, bentonite waterproof blanket construction convenient, water swelling after the pad formed in high density uniform colloidal waterproof layer, high density colloid formed by swelling of bentonite have exclusive performance of water, it can prevent water leakage effectively, anti leakage effect is good, strong resistance to failure.
