Seeking the smallest dewatering cake mixing percentage which is

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method and an execution method capable of reducing a manufacturing cost of an impervious soil.;SOLUTION: The soil is mixed with a dehydrated cake, at the same time, a mixed ratio of the cake is varied, and the connection with a coefficient of permeability with the variations in the mixed ratio of the cake is obtained. The soil is mixed with the cake so as to obtain the mixed ratio corresponding to the coefficient of permeability required for an impervious soil layer execution area to manufacture the impervious soil by making mechanical stabilization so as to increase fine-grained fractions. The impervious soil is spread over the execution area and is rolled to execute an impervious soil layer.;COPYRIGHT: (C)2003,JPO
