METHOD FOR MAKING WATERPROOFING SHEET INTEGRATED WITH CONCRETE LINING IN TUNNEL AND TUNNEL CONSTRUCTION METHOD

摘要

A waterproof sheet constructed to be integrated with a concrete lining in a tunnel between a shotcrete layer of an inner wall of the tunnel and the concrete lining is disclosed. The waterproof sheet includes a synthetic resin sheet; a non-woven fabric intermittently connected to the upper part of the synthetic resin sheet by point or line welding; a fixed wing attached to the non-woven fabric to be fixed to a shotcrete lining by a nail driven to the shotcrete layer; and a non-woven fabric thin film formed on the outer surface of the synthetic resin sheet with a thickness thinner than the synthetic resin sheet to integrate the concrete lining and the waterproof sheet when the concrete lining is constructed.
