Definitions

  • the invention relates to a method according to the Preamble of claim 1.
  • the aim of the invention is to avoid this disadvantage and to propose a method of the type mentioned at the beginning, in which A high level of security is guaranteed that the anchor or Skewer maintains its position during the pressing of the hardening mass.
  • the proposed measure ensures that the anchor or spit is carried away by the emerging highly viscous mass is and therefore with the simultaneous axial movement of the Drill pipe remains in the deepest end of the borehole.
  • the highly viscous mass also makes it radial Migration of the anchor or spit is a very considerable resistance opposite, creating a high degree of positional accuracy of the anchor or skewer is ensured. Due to the high viscosity Mass-related high position stability of the anchors can also Anchor ropes are used.
  • the injection compound can be anchor mortar, synthetic resin and the like but also act as pasty explosives.
  • Another object of the invention is a device to propose to carry out the method according to the invention.
  • the one at one end have a head provided with a cutting edge.
  • the head of the anchor in the axial direction against the drilling direction supported. This makes it necessary to anchor the anchor into the drill head to use.
  • the Anchor may only have a maximum length than the marshalling area corresponds to a drill carriage receiving the drill pipe, in other words, it must match the length of the anchor Drill mount can be used.
  • the aim of the invention is to avoid this disadvantage and to propose a device according to the preamble of claim 2, where also anchors with a the marshalling area of the used Length of the drill carriage can be used can.
  • this is in a device according to the Preamble of claim 2 by the characterizing features of Claim 2 reached.
  • the proposed measures are far-reaching Closure of the opening of the opening of the drill head ensured, the drill head even without inserted anchor is fully usable. This makes it possible to drill the hole first and then insert the anchor into the drill pipe. Problems with the are often encountered during drilling a very substantial game inside the drill pipe Anchoring avoided. In addition, the length limitation of the Anchor with regard to the shunting length of the drill carriage used path.
  • the Drill head 1 which on its free end face with drill pins 2 Tungsten carbide is equipped with an opening 3, which is in axial Direction of the drill head 1 extends.
  • This breakthrough 3 points a non-circular cross-section and expands against the free Face of the drill head.
  • the opening 3 a substantially cross-shaped cross section.
  • a drill stub 4 held at its free Has a cutting edge 5.
  • This drilling stub 4 is in supported in the axial direction against the drilling direction and is present the conical surfaces of the opening 3.
  • the drilling stub 4 with a transverse bore 6 provided, which is penetrated by a substantially U-shaped spring 7 is, the legs in pocket-shaped extensions 8 of the Breakthrough 3 engage and the drill stub by friction hold with the walls of breakthrough 3.
  • the legs in pocket-shaped extensions 8 of the Breakthrough 3 engage and the drill stub by friction hold with the walls of breakthrough 3.
  • the drill head 1 is in the usual way on a drill string 9 screwed on, which can also be formed in several parts.
  • the compression head 10 has in the usual way provided with the feed 11 Sleeve 12 on the inside of a circumferential groove 13 in the area of the feed 11, the sleeve one with the Drill pipe 9 encloses head 14 rotatably connected.
  • This Head 14 is provided with a central blind bore 15 which is against the interior of the drill pipe 9 is too open and has a cross hole 16 with the circumferential groove 13 of the sleeve 12 in connection stands.
  • the sleeve 12 is against the head 14 by means of seals 17 sealed.
  • a rotary hammer (not shown) engages on the head 14 who can engage in the blind bore 18.
  • an anchor In the manufacture of an anchor according to the invention by means of the drill head 1, in which a drill stub 4 is held and which is connected to a drill pipe 9, a hole in the securing rock formation advanced. This can be done in the drill pipe 9 an anchor 19 may also be introduced, this is necessary However not.
  • a washing-up liquid is poured over the Interior of the drill pipe supplied to the drilling site.
  • the contribution the detergent is carried out via a rinsing head, which is also known as Compression head 10 can be formed.
