Abstract (en)
[origin: WO2005090753A1] The invention concerns a method and device for boring, particularly percussion boring or rotary percussion boring, a hole (2) in soil or rock material and for forming an anchoring. According to the invention, a borehole (2) is formed by inserting a drill bit (4), and a casing tube (7) is placed inside the borehole (2) during the boring process. Once the borehole (2) is completed, the boring rods (5) are detached from the drill bit (4) and removed from the borehole (2). The periphery of the casing tube (7) is provided with a number of passage openings (23) for discharging hardenable material. A tensioning device (13, 14) for the anchor, particularly an anchor plate and a screw that can be screwed onto the casing tube (7), can be fixed to the end of the casing tube (7) protruding from the borehole (2). Anchoring or fixing elements (15) for anchoring the casing tube (7) on the surrounding inner wall (2) of the borehole are provided, in particular, on the end area of the casing tube (7) oriented toward the drill bit (4).
