A method and device for boring, particularly percussion boring or rotary
percussion boring, a hole in soil or rock material and for forming an
anchoring. A borehole is formed by inserting a drill bit, and a casing
tube is placed inside the borehole during the boring process. Once the
borehole is completed, the boring rods are detached from the drill bit
and removed from the borehole. The periphery of the casing tube is
provided with a number of passage openings for discharging hardenable
material. A tensioning device for the anchor, particularly an anchor
plate and a screw that can be screwed onto the casing tube, can be fixed
to the end of the casing tube protruding from the borehole. Anchoring or
fixing elements for anchoring the casing tube on the surrounding inner
wall of the borehole are provided, in particular, on the end area of the
casing tube oriented toward the drill bit.
