CONTAMINATED SOIL PURIFICATION METHOD
To provide a contaminated soil purification method which adopts an all-casing method, and can further avoid non-efficiency generated by partially overlapping adjacent improvement bodies.SOLUTION: A contaminated soil purification method is a method for purifying soil in an object range by constructing columnar improvement bodies while partially overlapping, and includes an excavation step, a backfilling step and a pull-out step. The backfilling step backfills a recycling material into the whole casing excavated by an all-casing method, and the pull-out step pulls out the casing. The recycling material used in the backfilling step is a material which can be easily separated from contaminated soil even when being mixed with the contaminated soil.SELECTED DRAWING: Figure 10
【課題】オールケーシング工法を採用したうえで、隣接する改良体が一部重複することによって生ずる非効率を回避することができる、汚染土壌浄化方法を提供する。【解決手段】本願発明の汚染土壌浄化方法は、柱状の改良体を一部重複させながら構築していくことで対象範囲の土壌を浄化する方法であり、掘削工程と、埋め戻し工程、引き抜き工程を備えている。埋め戻し工程では、オールケーシング工法により掘削したケーシング内全体に再利用材を埋め戻し、引き抜き工程では、ケーシングを引き抜く。なお、埋め戻し工程で用いる再利用材は、汚染土壌と混ぜ合わせたとしても汚染土壌から容易に分離できる材料である。【選択図】図１０
