Abstract (en)
The invention relates to a prestressed ground anchor. The longitudinal reinforcement (6) in the anchor is sealed into the ground by a hardened sealing slurry in which there is, around the armature, a tube (2) designed to resist the prestressing tension but which is broken by a tension exerted on the reinforcement which is greater than the prestressing tension but insufficient to break the reinforcement. <IMAGE>
Abstract (fr)
L'invention concerne un tirant précontraint. L'armature longitudinale (6) du tirant est scellée au terrain par un coulis de scellement durci dans lequel se trouve, autour de l'armature, un tube (2) apte à résister à la traction de précontrainte mais qui est rompu par une traction, exercée sur l'armature, supérieure à la traction de précontrainte mais insuffisante pour rompre l'armature. <IMAGE>
