UNDERGROUND WATER INSULATION WALL AND CONSTRUCTION METHOD OF UNDERGROUND WATER INSULATION WALL
To provide an underground water insulation wall that has both sufficient impermeable performance and deformation followability, and a construction method of underground water insulation wall with which the quality of underground water insulation wall is stable, and the environmental load can be suppressed during construction.SOLUTION: An underground water insulation wall 1 that is built underground by solidifying soil cement 10 made by mixing and agitating ground soil with cement milk with solidifying material containing bicarbonate has an area where C-S-H gel exists in the cross section of soil cement 10 after solidification is more than 15% of the total area of the cross section.SELECTED DRAWING: Figure 5
【課題】十分な遮水性能と変形追随性とを両立する地中遮水壁、及び、地中遮水壁の品質が安定し、かつ、築造において環境負荷を抑制できる地中遮水壁築造方法を提供する。【解決手段】炭酸水素塩を含む固化材入りのセメントミルクと地盤土砂とを混合撹拌したソイルセメント１０を固化させて地中に築造される地中遮水壁１であって、固化後のソイルセメント１０の断面において、Ｃ−Ｓ−Ｈゲルが存在する領域の面積が、断面全体の面積の１５％以上である。【選択図】図５
