FILE MOULDING PROCESS AND TOOLING ASSEMBLY FOR IMPLEMENTING THE SAME Abstract A pile moulding process comprises feeding a setting ma- terial (6) into a pioneer hole (1) or into the soil, With high-voltage discharges of electricity induced in the mate- rial (6) fed in, and displacing the material-supply and discharge-induction zone (7) along the height of the pile being moulded. The total energy of discharges at a given depth is such that the respective section of the hole (1) or of the soil is widened to match the pile diameter specified for the given depth. The effect of discharges is to create around the pile being moulded a fixed-soil zone (3) of higher strength and a compacted-soil zone (9) featuring improved construction properties. The tooling assembly for pile moulding comprises a pipe (3) to supply material and an electric discharger complete with electrodes (10 and 11) arranged coaxially, spaced apart, and mounted over an insulation rod (15) passed through the first electrode (10). The first electrode (10) is connected with that end of the pipe (3) which contains its discharge opening (17) so that its axis is parallel with that of the pipe (3) and the distance between the second electrode (11) and the discharge opening (17) of the pipe (3) is not less than the interelectrode space (16).
