To provide a method for constructing a high performance impervious wall having impervious performance required for confining polluted soil even in the sand ground having a high coefficient of permeability by a deep mixing method of soil stabilization for reducing a discharge quantity of excavation sludge.
This construction method of the impervious wall by the deep mixing method of soil stabilization, forms the impervious wall having a coefficient of permeability of 10-6cm/sec or less, by solidifying the ground by being agitated and mixed by injecting cement milk of blending a surface active agent by about 1% into the ground of an original position as a dispersing agent for enhancing fluidity, by blending bentonite for reducing the coefficient of permeability by 10 to 20% of cement weight, by setting the weight ratio W/C of water to cement to about 80 to 100%.
