Title (EN) HELICAL PILE LEADS AND EXTENSIONS
(FR) PAS ET EXTENSIONS DE PIEU HÉLICOÏDAL
Abstract: front page image
(EN)The present disclosure provides helical pile leads and extensions with closely spaced perimeter shear helical plates that develop a cylindrical failure surface between the perimeter shear helical plates and soil as the helical pile is rotated into the ground, mobilizing soil-to-soil shear strength, and thus increasing the stability, stiffness and load capacity of the helical pile.
(FR)La présente invention concerne des pas et extensions de pieu hélicoïdal avec des plaques hélicoïdales de cisaillement périmétrique étroitement espacées qui développent une surface de rupture cylindrique entre les plaques hélicoïdales de cisaillement périmétrique et le sol lorsque le pieu hélicoïdal est tourné dans le sol, mobilisant la résistance de cisaillement sol-sol et augmentant ainsi la stabilité, la rigidité et la capacité de charge du pieu hélicoïdal.
