Waterproof wall and product trash disposal place system null for product trash disposal place

摘要

PROBLEM TO BE SOLVED: To obtain an impervious wall of a waste disposal plant, which wall has the nature to buffer the impact and heavy pressure received from waste, has sufficient compressive strength, retains the original shape without flattening in spite of the receive of a large load and allows easy and rapid installation and execution and waste disposal plant system provided with such pressure tightness. ;SOLUTION: This impervious wall is formed to a three-layered structure by a planar buffer material 11 which is constituted by affixing and forming net layers 2 and 2 formed with many water permeation holes on both front and rear surfaces of a buffer layer 1 arrayed, in parallel, with many corrugated tapes 1a... consisting of synthetic resin tape blanks formed to a prescribed width and formed to a corrugated shape in side view, apart prescribed intervals with each other and is provided with flexibility windable in a longitudinal direction, a lower impervious sheet 12 which is disposed on the rear surface side thereof and an upper impervious sheet 13 which is disposed on the front surface side of the planar buffer material 11. A stationary frame 14 is formed along a circumferential direction on the lower impervious sheet 12 and the planar buffer material 11 is laid on the front surface side therof. Further, the upper impervious sheet 13 is laid on the entire front surface of the lower impervious sheet 12, by which the waste disposal plant system is obtd.;COPYRIGHT: (C)1999,JPO
