Abstract
To manufacture a pile which is intended to take compressive as well as tensile loads or to serve as a reinforcement member in soils, a strip is wound off a roll of strip material and is carried through a rotating-roller shaping unit in which the strip is shaped by rollers. If desired, the unit is operated in such a manner that it forms a bend in the direction of pile advancement. A pile thus shaped is driven from the roller shaping unit by means of pressure in arbitrary directions into the mass of an earth layer. Upon attainment of the desired depth of penetration and/or pile length the pile is severed at or close to the upper surface of the earth layer.
