<p>To manufacture a pile (9, 14) which is intended to take compressive as well as tensile loads or to serve as a reinforcement member in soils, a strip (4) is wound off a roll (3) of strip material and is carried through a rotating-roller shaping unit (6) wherein the strip (4) is shaped by rollers and, if desired, in such a manner that it forms a bend in its direction of advancement. A pile (9, 14) thus shaped is driven from the roller shaping unit (6) by means of pressure in arbitrary directions into the mass of an earth layer (10, 13, 16, 19). Upon attainment of the desired depth of penetration and/or pile length the pile (9, 14) is severed at or close by the surface of the earth layer (10, 13, 16, 19).</p> |
