WATERPROOF SHEET FOR TUNNEL WATERPROOF CONSTRUCTION INCLUDING DOT FOR PREVENTION OF DAMAGE

摘要

waterproof sheet for waterproofing tunnel construction is initiated. According to one embodiment of the present invention , a sheet made of a material such as a deflection surface for the construction and installation , by being formed of a plurality of different height to each other on one side of the sheet , the concave-convex portion is formed to be in contact with the irregular surface construction while that between the respective receiving part , and a protrusion to prevent damage to the sheet spaced from the concave-convex part . According to the present invention, there is yet to be a reliable installation with respect to the concave-convex portion of the irregular surface construction , and to prevent damage due to the uneven portion , improving the workability and construction quality by minimizing the resistance of the concavo-convex portion of the side construction has the advantage to having . ;
