Definitions

  • the present invention relates to a method for drilling holes in soil material and for securing an anchor in a borehole, wherein an expansion element fixed to a drill or anchor rod and a spreading, in particular sleeve-shaped, expansion element to be expanded with a Bohrkrone provided drill or anchor rod simultaneously with the formation of the borehole in the soil or rock material, in particular by a rotating and beating or rotating drilling is introduced, the expansion element after completion of the borehole by retracting the drill or anchor rod and the expansion element disposed thereon is widened into the interior of the expansion element in abutment against the borehole wall and the drill or anchor rod is secured at its end protruding from the borehole with an anchor plate on a borehole outside, as well as a device for drilling holes in ground or .
  • the anchoring or expansion of the expansion element is in this case, as for example in the AT-PS 409 785 or in the US 2009/0114402 is described, by retraction of the fixed to an anchor rod spreader or by retraction of an expander in an expansion sleeve, whereupon the expansion sleeve is brought into contact with the borehole wall reached.
  • either a further determination of the anchor can be made by introducing a curable suspension or the anchorage formed by the spreading of the expansion element into the mountain interior or the widening of the expansion element to the borehole wall is completed.
  • Such a procedure is on the one hand associated with time-consuming steps and, moreover, all a ready to be made anchorage forming elements each after completion of a previous step to the corresponding device grown or hinged thereto and are brought into the intended for their Endinsatz mixed position.
  • Such a procedure is in addition to the fact that it is time consuming, also costly and it is discarded in particular not inconsiderable lengths of the drill rods by sawing to the final required length, which on the one hand causes a shortening of the entire anchoring length and on the other hand, a plurality of additional , non-automatable work steps are required.
  • the trained as a neck element for the insertion device 14 nut 13 can be formed here as a nut 13 with both an internal thread and an external thread be on the one hand to be performed safely and reliably on the anchor rod 1, and on the other hand to ensure a safe attack of the insertion device 14 on the outer surface of the nut 13.
