Abstract

Un procédé de réalisation de pieu avec un dispositif de forage comprenant un outil rotatif à âme creuse et un outil téléscopable, dans lequel, une fois la profondeur souhaitée atteinte, on s'assure que la pression subie par l'outil téléscopable est relativement élevée, et avantageusement que l'intérieur de l'outil rotatif est en surpression, pour décider de l'extraction de l'outil rotatif, afin que les efforts subis fassent passer le dispositif de bétonnage de l'état rétracté, avec le tube de bétonnage de l'outil de bétonnage à l'intérieur de l'outil rotatif, à l'état déployé, avec le tube de bétonnage plongé dans le béton injecté dans l'excavation.
