CONTAMINATED SOIL PURIFICATION METHOD, AND PARTITION WALL BODY
PROBLEM TO BE SOLVED: To provide a contaminated soil purification method for resolving a problem with a conventional technology that, when an all-casing method is adopted, inefficiency results due to overlapping of a part of adjacent improvement bodies, and a partition wall body used with the same.SOLUTION: A contaminated soil purification method of the present invention is the method that purifies soil in a selected range, by constructing a columnar improvement body while made to partially overlap with each other. The contaminated soil purification method includes an excavation step, a compartment formation step, a body part back-fill step, an overlapped part back-fill step, and a pull-out step. In the compartment formation step, a partition wall body is erected in a casing excavated by an all-casing method, and a main compartment is formed at an overlapped part by the casing and the partition wall body. In the body part back-fill step, the body part is back-filled with clean soil. In the overlapped part back-fill step, the main compartment is back-filled with excavated contaminated soil or a recycled material separable from the contaminated soil.SELECTED DRAWING: Figure 7
【課題】本願発明の課題は、従来技術が抱える問題を解決することであり、すなわち、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、汚染土壌浄化方法とこれに用いる隔壁体を提供することである。【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、隔室形成工程、本体部埋め戻し工程、重複部埋め戻し工程、引き抜き工程を備えている。隔室形成工程では、オールケーシング工法により掘削したケーシング内に隔壁体を建て込み、重複部にケーシングと隔壁体によって主隔室を形成する。本体部埋め戻し工程では、本体部に清浄土を埋め戻し、重複部埋め戻し工程では、主隔室内に掘削された汚染土壌、又は汚染土壌と分離可能な再利用材を埋め戻す。【選択図】図７
