METHOD FOR SIMULTANEOUSLY IMPROVING CONTAMINATED SOIL AND CONSTRUCTING FOUNDATION OF OVERLAID STRUCTURE
To provide a construction method capable of shortening a construction period and suppressing a construction cost when constructing a foundation for supporting an overlaid structure on a contaminated soil requiring an improvement treatment.SOLUTION: A construction method for simultaneously improving contaminated soil and constructing a foundation for supporting an overlaid structure comprises: a soil improvement step of improving contaminated soil by adding a soil improvement material containing blast furnace slag, Portland cement and gypsum as main components to the contaminated soil and mixing and agitating; and a foundation construction step of constructing a foundation consisting of pile-shaped soil cement columns in the ground by using the soil improvement material.SELECTED DRAWING: Figure 1
【課題】改良処理が必要とされる汚染土壌に上載構造物を支持する基礎を構築する場合において、施工期間を短縮でき、施工コストを抑制することが可能な施工方法を提供すること。【解決手段】汚染土壌の改良と上載構造物を支持する基礎の構築とを同時に行う施工方法であって、汚染土壌に対して、高炉スラグ、ポルトランドセメントおよび石膏を主成分として含む土壌改良材を投入し、混合攪拌することで汚染土壌を改良する土壌改良工程、および、前記土壌改良材によって、地中に、杭状のソイルセメントコラムからなる基礎を構築する基礎構築工程を含む。【選択図】図１
