WATERPROOF MEMBER FOR TUNNEL AND WATERPROOF STRUCTURE FOR TUNNEL, WATERPROOF CONSTRUCTION METHOD FOR TUNNEL USING THE SAME

摘要

The present invention is formed by a laminated structure of multiple sheets 1 and the tarpaulin 2, relates to a tunnel (10) inside the shotcrete layer 11 and the lining concrete layer 12, waterproof member 100 for a tunnel to be provided between, so as to combine the multiple sheet 1 and the tarpaulin 2, the drainage sheet (1) water formed in the deep portion of the sheet bonding portion (110); Shotcrete layer to bond to the surface of the substrate 11, multiple sheets (1) of the waterproof sheet engaging portion shotcrete layer formed adjacent to both sides in the width direction of the bonding portion 110, 120; To engage with the adjacent side portions of the drainage sheet (1a), a multiple sheet 1 of shotcrete layer combination 120 multiple sheet engaging portion formed on the side edges in the width direction of the (130); A waterproof sheet engaging portion 140 formed on the side edges in the width direction to engage with the adjacent edge portions of the waterproof sheet (2a), water resistant sheet (2); By providing a water-proof member 100 comprising the integrated tunnel, and to minimize the risk of damage and leakage occurs in the quality according to the construction.
