ABSTRACT:
According to the invention, a casing pipe is set on the ground and filled with a fluid, whereupon electric pulses are passed through the fluid to produce a series of electric discharges. The casing pipe is driven into the ground due to the resultant electrohydraulic effect. While the casing pipe is being pulled from the ground, it is filled with concrete mix which is compacted by passing electric pulses therethrough to produce electric discharges. The installation for effecting this method comprises a pile puller, a pile driver and a concrete feeder, all connected to the casing pipe. The pile driver incorporates a fluid feed system communicating with the casing pipe, and a pulse device with electrodes installed at the lower portion of the casing pipe, which is intended to produce electric discharges in the fluid fed into the casing pipe by the fluid feed system.
