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.
A method for producing cast-in-situ piles, comprising setting a casing pipe on the ground, feeding a fluid into the casing pipe, passing electric pulses through the fluid to produce electric discharges having parameters such that permit hydraulic shock waves to be formed at the lower portion of said casing pipe, acting on the ground and on said casing pipe so as to drive the latter into the ground to a prescribed depth, whereafter the casing pipe is pulled from the ground as concrete mix is concurrently fed into said casing pipe and electric discharges are produced in the concrete mix to compact it.
A method for producing cast-in-situ piles, comprising assembling grillage sheathing on the ground, setting a casing pipe on the ground therein, feeding a fluid possessing the properties of a binder into said casing pipe, and passing electric pulses through said fluid to produce electric discharges releasing energy resulting in hydraulic shock waves induced at the lower portion of said casing pipe and acting on the ground and on said casing pipe so as to drive said casing pipe into the ground being impregnated with the binder, and wherein the amount of energy released by electric discharges per unit of time and per unit of ground area covered by hydraulic shock waves is varied so as to produce a pile of a variable cross-section, and after driving the casing pipe to a prescribed depth, it is pulled out from the ground as concrete mix is concurrently fed into said casing pipe and electrical discharges are produced in said concrete mix so as to compact it and thereby form the underground portion of the pile, and on pulling said casing pipe from the ground, electric discharges for compacting the concrete mix are produced in said grillage sheathing to thereby form the overground portion of the pile being produced.
