CUTOFF WALL FOR BLOCKING THE MOVEMENT OF CONTAMINATED UNDERGROUND WATER WITH FILLER COMPOSED OF SAND, SILT AND BENTONITE

摘要

PURPOSE: A cutoff wall for blocking the movement of contaminated underground water is provided to have the optimum workability in a construction site and to calculate the low coefficient of permeability below the suggested value. CONSTITUTION: The cutoff wall for blocking the movement of contaminated underground water contains filler composed of 86¯88 weight percent sand, 10¯12 weight percent silt and 2¯4 weight percent bentonite, wherein the moisture content of the filler is controlled to have the slump value of 5¯ 15 centimeters.
