Abstract (en)
[origin: WO02088523A1] The invention relates to a method and a device for the drilling, in particular the percussive or percussive rotary drilling of a hole (7) in earth or rock and for securing an anchorage in said hole. According to the invention, a bore hole (7) is created by a drill bit (1) mounted on a drill pipe (5) and a sliding sleeve (4) that surrounds the drill pipe (5) at a distance is simultaneously introduced. The invention is characterised in that a sliding sleeve (4) configured with a longitudinal slit (8) is introduced at least partially and rests substantially against the bore hole (7) during the drilling, whereby a reliable anchorage can be achieved with a simple construction by means of the sliding sleeve (4) with a longitudinal slit.
