Mineralogical name of bentonite montmorillonite, bentonite natural chemical composition is divided into sodium and calcium-based two categories. Bentonite has a water swelling properties, while the general calcium bentonite expands Edison Group, its expansion is only about three times its own volume, while the water itself five times the weight of the composite film Edison Group adsorbed sodium bentonite water volume expanded to 15-17 times more than the original, 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 percent of laid along the slope to minimize the long direction of the lap number geotextile Edison Group, the slope of the GCL must exceed 1500mm above the toe line. D, we will be in strict accordance with the submitted to the supervising engineers design waterproof blanket laying Hongxiang Chemical Fiber Group plans to lay water network, 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 ℃. Waterproof blanket construction method: 1, waterproof blanket material larger self, should adopt the shovel transport aircraft 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 ℃. If GCL damaged during the installation process (tear, puncture, etc.), can be cut from a roll of a new piece of bentonite blanket "patch" to cover the damaged areas repaired. Where the length of the sides away from the damaged patch can not be less than 300mm, laying "patch" the former should sprinkle some granular bentonite or bentonite slurry around the damage. If necessary, you can use some adhesive to prevent the "patch" shift, or where a small piece of broken bentonite blanket underneath.
