A method for producing a screw foundation (1) for anchoring building parts or structures in the ground, comprising the following steps: providing a tubular starting material (10) with a required length, laying a free end (12) of the tubular starting material (10) between at least two shaped elements (20), securing the tubular starting material (10) in its longitudinal direction, compressing the free end (12) of the tubular starting material (10) by moving together the at least two shaped elements (20), with the result that an at least partially tapering region (14) is formed on the free end (12) of the tubular starting material (10), and forming a screw-like or helical thread (16) on the at least partially tapering region (14).
L'invention concerne un procédé de réalisation d'un pieu foré (1) pour l'ancrage dans le sous-sol d'éléments ou de constructions, comprenant les étapes consistant à : disposer d'un matériau de départ tubulaire (10) de la longueur voulue, placer une extrémité libre (12) du matériau de départ tubulaire (10) entre au moins deux corps moulés (20), immobiliser le matériau de départ tubulaire (10) dans sa direction longitudinale, comprimer l'extrémité libre (12) du matériau de départ tubulaire (10) par un rapprochement desdits au moins deux corps moulés (20), ce qui forme à l'extrémité libre (12) du matériau de départ tubulaire (10) une zone (14) au moins localement rétrécie, puis pratiquer un filetage hélicoïdal ou en spirale (16) dans la zone (14) au moins localement rétrécie.
