WATERPROOF, ROOT BARRIER, DRAINAGE FUNCTION TO UNIFICATION FOR HYBRID ROOT BARRIER SYSTEM AND ITS CONSTRUCTION METHODE

摘要

PURPOSE: A hybrid root-proof structure having waterproof, root-proof, and draining functions and a construction method thereof are provided to simplify an installation work by thermally fusing a nonwoven fabric on the top of a drain board using the extruded latent heat of the drain board. CONSTITUTION: A hybrid root-proof structure(100) having waterproof, root-proof, and draining functions comprises metal fixtures, a waterproof sheet(130), a drain board(110), and a nonwoven fabric(120). The metal fixtures are fixed to the artificial ground at uniform intervals. The waterproof sheet is placed on the artificial ground by receiving the metal fixtures. The drain board is placed on the waterproof sheet and has multiple cylindrical spacing supports(112) for supporting a drain layer and a soil layer. The nonwoven fabric is fused on the tops of the spacing supports using the extruded latent heat of the drain board.
