A method and a device for intermittently exerting forces on soil.

摘要

A method and a device for consolidating soil or driving a pile into the ground by thrusting forces transferred to the soil or the pile through transmission means, said forces being derived from at least two sources, viz. a mass load and a vibratory member which is adapted to produce a varying vertical thrusting force and to be brought successively out of and shockwise into engagement with said transmission means.
