CONSTITUTION:A water-impermeable wall 1 is constructed in the surrounding ground of a preset ground Wa to be improved in soft ground W, a water-pumping pipe 4 with a well point 3 is driven into the ground Wa, and an infiltration pipe 5 whose one end is to be connected with the pipe 4 and the other end is to be connected with a pump (not illustrated) is laid.
