Title:
地中遮水壁及び地中遮水壁築造方法
Document Type and Number:
Japanese Patent JP7169666
Kind Code:
B2
Abstract:
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
