SOIL IMPROVEMENT METHOD AND SOIL IMPROVEMENT BODY
To reduce the amount of cement-based solidification material used in the soil improvement body and reduce the construction cost.SOLUTION: A ground improvement method for improving a ground G in which at least two strata out of strata consisting of volcanic ash soil, cohesive soil, sandy soil, and gravel soil are stacked comprises a step of excavating clay G1 and gravel G2 in an area to be improved and temporarily placing them on each ground, a step of refilling an excavated hole 11 with the clay G1 and the gravel G2 temporarily placed in an appropriate ratio and mixing and agitating, or mixing and agitating outside the excavated hole 11 and refilling the excavated hole 11, and a step of injecting a cement-based solidifying material K into the mixed soil G10 created in the excavated hole 11.SELECTED DRAWING: Figure 5
【課題】地盤改良体に用いるセメント系固化材の使用量を低減することができ、施工コストの低減を図ることができる。【解決手段】火山灰質土、粘性土、砂質土、及び礫質土からなる地層のうち少なくとも二つの地層が積層されてなる地盤Ｇを改良する地盤改良方法であって、改良領域における粘土Ｇ１と砂礫Ｇ２を掘り出してそれぞれの地盤毎に仮置きする工程と、仮置きされている粘土Ｇ１と砂礫Ｇ２を適宜な割合で掘削穴１１に埋め戻して混合攪拌する、又は掘削穴１１の外で混合攪拌して掘削穴１１に埋め戻す工程と、掘削穴１１内において作成した混合土Ｇ１０にセメント系固化材Ｋを注入する工程と、を有する地盤改良方法を提供する。【選択図】図５
