EROSION-CONTROL SHEET AND SUCTION PREVENTIVE CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To excellently maintain erosion controllability even when the leveling accuracy of a laying surface is lowered when the erosion control treatment of revetment for a reclaimed land is conducted by using an erosion-control sheet in which short-fiber nonwoven fabrics and wire gauze members are superposed and unified. ;SOLUTION: The erosion-control sheet 10 laid on the surface of a back-filling stone layer or the like and made to cope with the scour and suction of soil and sand on a reclaimed land is composed of a wire gauze member 15 and a sheet material 16 comprising short-fiber nonwoven fabrics in thickness of T. The sheet member 16 is constituted by superposing the short fibers of polyester in a cottony shape, the extensibility of the sheet member is set excellently, and the sheet member is made to follow up to the deformation of the wire gauze member and deformed, but erosion controllability can be displayed superiorly, and characteristics as the erosion-control sheet can be maintained even when the leveling accuracy of the back-filling stone layer is lowered.;COPYRIGHT: (C)2001,JPO
