Abstract (en)
[origin: WO9821439A1] In a process for drilling, in particular rotary percussion or percussion drilling, and lining holes in the ground or rocks, a hole (13) is percussion and/or rotation drilled by a cutter (1, 2, 3) mounted on boring rods (9) and a lining is formed by a jacket tube (5). During drilling, at least one jacket tube (5, 5') coupled to the cutter (1, 2) is drawn in the axial direction by the cutter (1, 2, 3) into the bore hole (13) and once drilling is finished, the cutter (3) is at least partially removed from the jacket tube (5, 5') together with the boring rods (9). In a device for drilling, in particular percussion or rotary percussion drilling, and lining holes in the ground or rocks, a cutter (1, 2, 3) mounted on boring rods (9) drills a bore hole by percussion and/or rotary drilling. The cutter (1, 2, 3) is divided in the radial direction. At least one jacket tube (5, 5') which surrounds the boring rods (9) is located at the end of the cutter (3) away from the drilling surface, around the outer circumference of the cutter (3), and is form-fittingly joined to the cutter (1) by at least one coupling element (6) so as to be drawn in the longitudinal direction of the bore hole (13).
