Waterproof blanket (GCL) is a new type of geosynthetics. It is graded by a natural sodium bentonite particles and the corresponding mixing additives made by special technology and equipment, the bentonite particles is fixed between two layers of waterproof blanket use of geotextiles, made of waterproof blanket, All features both a geotextile material, but also has excellent water (seepage) performance. Waterproof mechanism is: water swelling bentonite particles to form a homogeneous colloidal system, Edison waterproof blanket in the lower layers of geotextile limit the role of the bentonite from disorder into order expansion waterproof blanket performance, ongoing The result is to let the swelling bentonite layer itself achieve dense, which has a waterproof effect. Waterproof blanket Main Specifications: Bentonite expansion coefficient (ml / 2g) ≥24; GCL mass per unit area (g / m2) ≥4500; GCL longitudinal breaking strength (KN / m) ≥10; GCL transverse rupture strength (KN / m) ≥10; GCL longitudinal elongation at break (%) ≤10; GCL transverse elongation at break (%) ≤6; GCL vertical permeability coefficient (cm / s) ≤5 × 10-9; GCL peel strength (N) ≥ 65; GCL anti hydrostatic testing (0.5Mp) 24 hours without leakage. Mineralogical name of bentonite montmorillonite, bentonite natural chemical composition is divided into sodium and calcium-based two categories. Bentonite has a water swelling characteristics of bentonite waterproof blanket, general calcium bentonite expands when its expansion is only about three times its own volume, and five times its own weight of water adsorbed sodium bentonite water, volume expansion to the original 15 -17 times more than the sodium bentonite locked in between two layers of geosynthetic materials for protection and strengthening of the role of the GCL has a certain overall shear strength. Construction method of a waterproof blanket, waterproof blanket material larger self, should adopt the shovel machine with waterproof blanket lifting tool handling, laying. 2. Connect waterproof blanket material using an overlapping manner. 3, should be waterproof blanket on slopes greater than 10% of the number of laying minimize overlap along the longitudinal direction of the slope, the slope of the GCL must toe the line more than 1500mm above. D, we will be in strict accordance with the submitted to the Engineer's waterproof blanket to lay laying design, except with the owner or supervision requirements. 4, any equipment used for laying waterproof blanket has been laid not traveling well above geosynthetics. When installing waterproof blanket, outdoor air temperature not lower than 0 ℃ or above 40 ℃.
