SOIL CEMENT CONTINUOUS WALL METHOD
To provide a soil cement continuous wall method for reducing an influence on a peripheral ground of a construction site in ground excavation.SOLUTION: A soil cement continuous wall method includes an excavation hole formation step of forming an excavation hole 53 in the ground by a screw 25, and a stress material build-up step of building up a stress material 55 into the excavation hole 53, wherein a through hole 41 is provided in an agitating blade 33 of the screw 25, a curable fluid contains a fluidizing agent for improving fluidity of an agitated mixture 51, the excavation hole formation step and the stress material build-up step are repeatedly executed so that the adjacent excavation holes 53 partially overlap and are continuous, the next excavation hole formation step is executed after a next day of the excavation hole formation step, the excavation hole formation step jets air into the excavation hole 53 during excavation, and the excavation hole formation step includes processing of vertically moving the screw 25 in the excavation hole 53 during excavation.SELECTED DRAWING: Figure 2
【課題】地盤掘削において施工現場の周辺地盤への影響を低減するソイルセメント連続壁工法を提供する。【解決手段】ソイルセメント連続壁工法は、スクリュー２５で掘削孔５３を地盤に形成する掘削孔形成工程と、掘削孔５３に応力材５５を建て込む応力材建込工程と、を備え、スクリュー２５の撹拌翼３３には貫通穴４１が設けられ、硬化性流体は、撹拌混合物５１の流動性を向上させる流動化剤を含み、掘削孔形成工程及び応力材建込工程は、隣接する掘削孔５３同士が一部オーバーラップして連続するように繰返し実行され、掘削孔形成工程の翌日以降に次回の掘削孔形成工程が実行され、掘削孔形成工程では、掘削中の掘削孔５３内に空気が噴出され、前記掘削孔形成工程は、スクリュー２５が掘削中の掘削孔５３内で上下運動される処理を含む。【選択図】図２
