Claims

[Scope of Claim for Utility Model Registration] 1. Provided between the primary lining concrete and secondary lining concrete of a tunnel, - to prevent spring water from the lining concrete side from seeping into the secondary lining concrete side. In a waterproof sheet for preventing water-impermeable base sheet, a first adhesive layer that is continuous along the width direction is provided at one end in the length direction of one surface of the main body of the water-impermeable base sheet, and the length of one surface of the main body of the water-impermeable base sheet is When connecting the - waterproof sheet and other waterproof sheets by providing a second adhesive layer continuous along the width direction at the other end in the direction,
- the first adhesive layer of the tarpaulin and the second adhesive layer of the other tarpaulin
A waterproof sheet characterized by having an adhesive layer and an adhesive layer mutually bonded. 2 Practical use in which a frame for filling a heat-fusible material or an adhesive material for driving a fixing member is provided on one end of the other surface of the main body of the water-impermeable base sheet in the length direction at predetermined intervals along the width direction. A waterproof sheet as described in item 1 of the claim for new patent registration. 3. The waterproof sheet according to claim 2 of the utility model registration claim, in which the frame is filled with a heat-fusible substance or an adhesive substance in advance. 4. A utility model according to any one of claims 1 to 3, wherein a third adhesive layer is provided on the other end of the main body of the water-impermeable base sheet in the width direction, and is continuous along the width direction. Tarpaulin.
