UNDERGROUND IMPERVIOUS WALL AND UNDERGROUND IMPERVIOUS WALL CONSTRUCTION METHOD
To provide an underground impervious wall which achieves both sufficient impervious performance and deformation followability, and an underground impervious wall construction method which stabilizes quality of an underground impervious wall and can suppress an environmental load in construction.SOLUTION: An underground impervious wall 1 is constructed in the underground by solidifying soil cement obtained by mixing and stirring cement milk with a solidification material containing hydrogen carbonate, and ground sediment. The soil cement after solidification has a coefficient of permeability indicating an impervious condition of 10-7 cm/s or less and breaking strain indicating deformation followability and self-repair property of 2% or more.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、固化後の前記ソイルセメントは、遮水性を示す透水係数が１０−７ｃｍ／ｓ以下、かつ、変形追随性及び自己修復性を示す破壊ひずみが２％以上である。【選択図】図５
