CONSTRUCTION METHOD FOR UNDERGROUND BURIAL STRUCTURE
PROBLEM TO BE SOLVED: To provide a construction method for an underground burial structure that reduces construction costs and curtails a construction period.SOLUTION: A construction method for an underground burial structure, which is for constructing soil improvement structures 40a to 40l by underground burial, transversely across a conforming section 10 to a non-conforming section 20, comprises: a section wall burial process in which a section wall for sectioning a scheduled formation area from outside is buried; a removal process in which soil of the scheduled formation area, where a section wall has been buried in the section wall burial process, is removed; a formation process in which a contaminant diffusion prevention area 30 is formed by filling sound soil in the scheduled formation area from which soil has been removed in the removal process; another removal process in which a section wall buried along the periphery of the contaminant diffusion prevention area 30 that has been formed in the formation process is removed; and an underground burial structure burial process in which soil improvement structures 40e to 40g are buried, so as to lay out the soil improvement structures 40e to 40g in the contaminant diffusion prevention area 30.
【課題】施工コストを低減することが可能になると共に、施工時間を短縮することが可能になる、埋設構造物の施工方法を提供すること。【解決手段】埋設構造物の施工方法は、基準適合区画１０から基準不適合区画２０までを横断するように埋設される地盤改良体４０ａ〜４０ｌを施工する方法であって、形成予定領域を外部から区画するための区画壁を埋設する区画壁埋設工程と、区画壁埋設工程において区画壁が埋設された形成予定領域の土壌を取り除く除去工程と、除去工程において土壌が取り除かれた形成予定領域に健全土を埋設することにより、汚染拡散防止領域３０を形成する形成工程と、形成工程において形成された汚染拡散防止領域３０の外縁に埋設された区画壁を撤去する撤去工程と、地盤改良体４０ｅ〜４０ｇが汚染拡散防止領域３０に配置されるように、当該地盤改良体４０ｅ〜４０ｇを埋設する埋設構造物埋設工程と、を含む。【選択図】図２
