The present invention was devised to supplement the above problems, and provided with a heat shield for preventing carbonization of the nonwoven fabric from high heat during hot air bonding of the waterproof sheet, and the waterproof sheet is prevented by the pressure applied to the waterproof sheet when concrete is poured. In order to prevent damage, the waterproof sheet fixing packing is provided with a weakening ring to prevent the waterproof sheet fixing packing from being cut off before the waterproof sheet is damaged.

The purpose of the present invention is to prevent the damage of the waterproof sheet when the lining concrete works after the waterproof sheet is fixedly installed, the packing is torn first before the waterproof sheet is pushed and damaged by the pressure in the process of placing concrete. It is an object of the present invention to provide a packing for fixing a waterproof sheet.

Another object of the present invention is a waterproof sheet which prevents the nonwoven fabric from being damaged by heat damage by applying hot air around the airtight and waterproof sheet fixing packings by hot air in the process of thermally fixing the waterproof sheet to the fixing packing. The purpose is to provide a fixing packing.
