DIFFUSION PREVENTION WALL AND ITS CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a diffusion prevention wall which can eliminate a problem which occurs when constructing the diffusion prevention wall extending up to an impermeable layer, and can suppress that a contaminant and contaminated groundwater contained in contaminated soil diffuse to the outside of the diffusion prevention wall, and its construction method.SOLUTION: In a construction method of a diffusion prevention wall which constructs the diffusion prevention wall 10 for a contaminant which is contained in contaminated soil PS at a downstream side of a groundwater flow rather than the contaminated soil PS in soil G1 in which an impermeable layer G2 exists, the contaminated soil PS exists at an upper part of the impermeable layer G2, and the groundwater flow exists, and the construction method comprises an inclined part 1 which is inclined downward to the contaminated soil side, and constructs the diffusion prevention wall 10 whose lower end does not reach the impermeable layer G2.SELECTED DRAWING: Figure 4
【課題】不透水層まで延びる拡散防止壁を造成する際に生じ得る課題を解消することができ、かつ、汚染土に含まれる汚染物質や汚染地下水が拡散防止壁の外側へ拡散するのを抑制することのできる拡散防止壁とその造成方法を提供すること。【解決手段】不透水層Ｇ２が存在し、不透水層Ｇ２の上方に汚染土ＰＳが存在し、地下水流れがある土壌Ｇ１において、汚染土ＰＳよりも地下水流れの下流側に汚染土ＰＳに含まれる汚染物質の拡散防止壁１０を造成する拡散防止壁の造成方法であって、下方に向かって汚染土側へ傾斜した傾斜部１を備え、かつ、下端が不透水層Ｇ２に到達しない拡散防止壁１０を造成する方法である。【選択図】図４
