Application of Coated Natural Sodium Bentonite Waterproof Blanket in Municipal Engineering of Longping Road
Laminated natural sodium bentonite waterproof blanket,as an environmentally friendly waterproof material,is characterized by that it can expand to form a dense gelentiate diaphragm after water decomposition,so as to achieve a high degree of waterproof efficiency.This study expounds the construction technology and technical details of the waterproof layer of this type of waterproof blanket,combined with the evalua-tion of field impermeability after the construction,and strongly proves the wide potential and feasibility of the coated natural sodium bentonite waterproof blanket in open tunnel engineering.
