PERMEABLE GROUND WATER PURIFYING WALL AND GROUND WATER PURIFYING WALL

摘要

PROBLEM TO BE SOLVED: To provide a permeable ground water purifying wall capable of keeping a desired permeability over a long period of time and preventing the re- elution of heavy metals even if ground water is contaminated with a specific heavy metal, and a ground water purifying wall capable of treating contaminated ground water extending over a wide range while achieving cost reduction. ;SOLUTION: A ground water purifying wall 1 comprises a permeable ground water purifying wall 1a formed by disposing a wall-shaped region 11 including a permeable purifying material in the ground and a cut-off wall (a pair of cut-off walls 1b) gathering ground water (contaminated ground water 3) not having relation with the permeable ground water purifying wall 1a to bring the same to the ground water (contaminated ground water 3) having relation with the permeable ground water purifying wall 1a.;COPYRIGHT: (C)2000,JPO
