摘要
A method for uniformly improving a soft ground is proposed. It includes the steps of driving a pipe into the ground, putting sand thereinto and pulling up the pipe gradually while discharging and compacting the sand. In forming the sand piles, the diameter and/or strength of the sand piles are changed according to the soil nature of the ground to be improved to improve the ground uniformly.
