ABSTRACT:
A pile driving and pile removing method comprises the step of causing a water-in-oil type water swellable polymer particle emulsion to be present on the pile surface or in the vicinity thereof during driving or extraction. The presence of the emulsion reduces the frictional resistance between the pile and the ground, enabling smooth and easy driving and removing of the pile.
