Abstract
L'invention concerne une fondation d'ancrage à pieux en post-tension et un procédé associé, consistant à créer un vide ou un espace fortement compressible entre un ancrage à pieux forés ou foncés entourant un boulon d'ancrage ou une armature sous post-tension et le fond d'une coiffe de fondation. Le vide ou l'espace peut être formé au moyen d'entretoises compressibles ou d'éléments formateurs de vide placés entre le sommet de l'ancrage à pieux et la coiffe de béton. Du fait que le boulon ou l'armature d'ancrage est mis sous post-tension contre la coiffe, l'élément formateur de vide est comprimé ou écrasé, de sorte que l'ancrage est tiré vers le haut en direction de la coiffe, produisant une résistance à l'arrachement, et la coiffe est tirée vers le bas contre le sol environnant, constituant ainsi une fondation résistante pour un pylône ou une autre structure destinée à être montée sur cette fondation.
