摘要:
A method and a device for the drilling, in particular the percussive or percussive rotary drilling of a hole in earth or rock and for securing an anchorage in the hole. A bore hole is created by a drill bit mounted on a drill pipe and a sliding sleeve that surrounds the drill pipe at a distance is simultaneously introduced. A sliding sleeve configured with a longitudinal slit is introduced at least partially and rests substantially against the bore hole during the drilling, whereby a reliable anchorage can be achieved with a simple construction by the sliding sleeve with a longitudinal slit.
