- 遮水体で囲まれた地盤領域の表層を構成する透水層の下に拡がる飽和難透気透水層を貫通してさらに該飽和難透気透水層の下に拡がる被圧透水層に注水口が位置するように埋設された注水井戸を介して前記被圧透水層に注水し、該注水された水に前記飽和難透気透水層に含まれる汚染物質を連行させつつ該汚染物質が連行された水を前記透水層に吸水口が位置するように埋設された揚水井戸を介して地上に揚水し、揚水された水を水処理設備で処理して処理水とし、該処理水を前記水処理設備に連通接続された水タンクに送って貯留し、該水タンクに連通接続された注水管を介して前記水タンク内の処理水を前記注水井戸に送り、該注水井戸を介して前記被圧透水層に前記処理水を注水する循環工程からなるとともに、前記揚水井戸を介して地上に揚水する際、前記注水井戸内の水位が前記揚水井戸内の水位に対し所定の水頭差Hだけ定常的に高くなるようにかつ前記揚水井戸内の水位が所定の基準水位を上回らないようにすることで前記水頭差による水圧を利用した通水洗浄を行う難透気透水性汚染土壌の浄化方法であって、前記循環工程が連続して行われているとき、前記飽和難透気透水層に高圧空気を圧入することにより、圧入された空気容量に相当する水を前記飽和難透気透水層から排除して前記透水層へ強制移動させることを特徴とする難透気透水性汚染土壌の浄化方法。
