METHOD FOR PURIFYING GROUND
To provide a ground purification method in which pollutants in a penetration part can efficiently be cleaned up.SOLUTION: Provided is a method for purifying a ground G having an upper water permeable layer G1 on the top side of a low water-permeable layer G2 where a penetration part 20 extending in the vertical direction exists, and having a lower water permeable layer G3 on the underside of the low water-permeable layer G2, including: a step of expanding the water permeable area of the penetration part 20 from the upper water permeable layer G1 to the lower water permeable layer G3; and a step of injecting a purifying agent into the lower water permeable layer G3 or the upper water permeable layer G1 and pumping groundwater C containing the purifying agent from the upper water permeable layer G1 or the lower water permeable layer G3.SELECTED DRAWING: Figure 8
【課題】浸透部の汚染物質を効率的に浄化できる地盤浄化方法を提供する。【解決手段】地盤の浄化方法は、上下方向へ延びる浸透部２０が存在する低透水層Ｇ２の上面に上部透水層Ｇ１があり、低透水層Ｇ２の下面に下部透水層Ｇ３がある地盤Ｇの浄化方法であって、上部透水層Ｇ１から下部透水層Ｇ３に亘って浸透部２０の透水面積を拡げる工程と、下部透水層Ｇ３又は上部透水層Ｇ１へ浄化剤を注入し、上部透水層Ｇ１又は下部透水層Ｇ３から浄化剤を含んだ地下水Ｃを揚水する工程と、を有する。【選択図】図８
