Abstract

A method of forming on the ground surface a support column, such as a pile, of a filling material which can be introduced in a fluid condition into a column cavity to form said support column and which solidifies after curing, which it includes the operations of: a) placing a filling hopper and an excavating tip in relation to vertically and contiguously aligned along a vertical axis, in a selected place on the surface of the ground where a supporting column is to be formed; b) placing a vertically elongated intermediate pusher, in detachable application with the excavating tip, the pusher extending upwardly through the filling hopper, along said vertical axis; c) filling the hopper with a suitable amount of filler material to form the support column; d) forming a cavity of selected size and depth on the surface of the land by transmitting a driving force by means of said pusher extending through the filling hopper to the digging tip, to introduce it into the ground; e) selectively introducing said filling material into said cavity from said filling hopper by gravity; and f) removing said pusher from said filler material within the cavity; g) said pusher having the shape of an axially elongated tube in which the wall of the tube has a plurality of radial openings formed therein which allow said filling material to be transferred between places located outside said pusher and places situated inside said tube. Pusher, in its interior, during the progressive filling of said cavity by the movement of said excavating tip, said tube wall occupying an area, in cross section, substantially smaller than the cross-sectional area of the mentioned cavity being formed.
