CONTAMINATED SOIL PURIFICATION METHOD BY USING HIGH PRESSURE INJECTION AGITATION METHOD
To provide a contaminated soil purification method capable of preventing inflammation on treatment work and effectively purifying a contaminated soil involving high-concentration hydrocarbon oil such as gasoline.SOLUTION: A contaminated soil purification method by using a high pressure injection agitation method for purifying a contaminated soil G contaminated by gasoline by using a high pressure injection agitation method at an original position includes steps of: inserting an injection rod 2 assembled with an injection hole 2a at its tip to a contaminated soil G; and constructing a columnar soil improvement body K in the contaminated soil G by injecting a hardening material N together with compressed air from the injection hole 2a while rotating the injection rod 2.SELECTED DRAWING: Figure 1
【課題】処理作業時における引火を防止でき、かつ高濃度のガソリン等の炭化水素油を含む汚染土壌を効果的に浄化することができる。【解決手段】高圧噴射撹拌工法を用いてガソリンによって汚染された汚染土壌Ｇを原位置で浄化する高圧噴射撹拌工法を用いた汚染土壌浄化方法であって、先端部に噴射孔２ａを備えた注入ロッド２を汚染土壌Ｇに挿入する工程と、注入ロッド２を回転させながら噴射孔２ａから圧縮空気と共に硬化材Ｎを噴射して、汚染土壌Ｇ中に柱状の地盤改良体Ｋを造成する工程と、を有する高圧噴射撹拌工法を用いた汚染土壌浄化方法を提供する。【選択図】図１
