Patent

CA 2277942

A pile (1) has a plurality of external parallel helical fins (30, 31, 32) along substantially the whole length of the pile (1). At least one of the fins (30, 31, 32) has a wedge-shape cross section. The pile (1) can be driven into a substrate by applying a force to the pile (1) substantially parallel to the longitudinal axis (2) of the pile (1), the force having substantially no rotational component about the longitudinal axis (2). The helical fins (30, 31, 32) on the pile (1) cause the pile (1) to rotate in the substrate and thereby penetrate the substrate as the force is applied.

L'invention concerne un pieu (1) présentant, sur presque toute sa longueur, plusieurs filets (30, 31, 32) extérieurs hélicoïdaux parallèles. Au moins un des filets (30, 31, 32) présente une section transversale cunéiforme. On peut introduire le pieu (1) dans un substrat en appliquant sur le pieu (1) une force sensiblement parallèle à son axe longitudinal (2), la force n'ayant sensiblement aucun composant rotatoire autour de l'axe longitudinal (2). Les filets hélicoïdaux (30, 31, 32) du pieu (1) font tourner le pieu dans le substrat et le font donc pénétrer dans ce dernier, à mesure qu'on applique la force sur le pieu.
