Abstract

L'invention concerne un procédé et un dispositif pour le forage, notamment pour le forage par percussion ou par roto-percussion, d'un trou dans le sol ou la roche, ainsi que pour la fixation d'un ancrage dans le trou, un trou de forage étant formé par une couronne de forage (3) montée sur un train de tiges de forage (2). Selon l'invention, le train de tiges de forage (2) est entouré, au niveau de la face arrière opposée à la surface de taille (5) de la couronne de forage (3), notamment à distance de la couronne de forage (3), d'un élément d'ancrage (4) dont la dimension extérieure dépasse au moins partiellement la circonférence du trou de forage produit par la couronne de forage (3). Cela permet d'assurer, de manière simple et fiable, un blocage de l'ancrage dans un trou de forage.
