Abstract

L'invention concerne une technique qui facilite des opérations de fond de trou, telles que des opérations de cimentation. La technique utilise un train de tiges ayant un outil de pose actionné de façon hydraulique. Une colonne perdue est suspendue au train de tiges par l'intermédiaire d'un mécanisme libérable. Un ensemble de suspension de colonne perdue est couplé à la colonne perdue et relié mécaniquement à l'outil de pose actionné de façon hydraulique. L'actionnement hydraulique de l'outil de pose provoque l'actionnement mécanique de l'ensemble de suspension de colonne perdue. La structure permet l'utilisation d'un ensemble de suspension de colonne perdue qui n'a pas de piston d'actionnement hydraulique.
