Abstract

L'invention concerne un procédé de forage comprenant: - une étape de forage d'un trou dans Ie sol, au cours de laquelle un tube de forage (102) pourvu à l'une de ses extrémités d'un outil de coupe (106) désolidarisable dudit tube, est mis en rotation, l'outil de coupe émettant des vibrations, cette étape étant suivie par : - une étape de désolidarisation de l'outil de coupe lors de laquelle un objet (120) est déplacé dans le tube de forage axialement vers ladite extrémité de manière à chasser l'outil de coupe hors du tube de forage.
