Punching polyethylene self-adhered waterproof coiled material as well as preparation method and using method thereof

The invention discloses a punching polyethylene self-adhered waterproof coiled material as well as a preparation method and a using method thereof. A punching area and a self-adhering area are arranged on two sides of the coiled material in the length direction of the coiled material respectively; adhering holes are formed in the punching area at intervals, and the adhering holes are through holes; the self-adhering area is coated with a self-adhering adhesive. The preparation method comprises the following steps: in the production processing process, processing the coiled material on an assembly line in the punching area and the self-adhering area, forming the adhering holes in one side of the coiled material, and performing blade coating on the self-adhering adhesive on the other side ofthe coiled material. The using method comprises the following steps: (1) clearing a base layer; (2) paving cement gel, and adhering the punching area; (3) leveling the adhered punching area, so thatthe adhering holes can be
