Definitions

  • the invention relates to an injection drill anchor made of at least one steel tube.
  • Injection drill anchors are used in a wide variety of designs Connecting used rock layers used in particular in underground mining, but also routes and tunnels Keep cavities open.
  • WO 91/15657 discloses an injection drill anchor with an anchor tube, a drill bit at the anchor tip facing the deepest hole and Has flushing and injection openings.
  • the anchor tube is with a borehole closure and at the end protruding from the borehole with a detachable connection element.
  • the as Section formed drill with a trained as a drilling adapter Connection element is provided against a section designed as an anchor tube interchangeable, the section with a borehole closure and a check valve is provided.
  • each injection valve to be individually charged with the pressing medium so that the Pressing process in accordance with the local conditions of the borehole wall adapted manner can be carried out.
  • Which are the injection valves forming radial expansion of the anchoring body can be made more reproducible in this way.
  • DE 44 45 626 A1 makes the proposal to include an injection sliding drill anchor an inflatable packer, an inflatable jacket and a stable support tube equip and integrate a valve in the support tube. Via the inflation valve the inflatable packer is fixed, this process only being initiated when the drilling is finished. For this, at the beginning of the Injection process, a valve body is flushed into the inflatable packer, which attaches itself supports a valve seat provided and trained there. The The valve body is replaced by pressure increase after the expansion work destroyed, so that then injection material in the force application area can penetrate.
  • the inflatable packer is equipped with a post-injection valve, which enables re-pressing of the free spin track.
  • the object of the invention is based on the prior art based on creating an injection drill anchor, which even with one less stable mountains securely and positionally fixed in a borehole can be.
  • the invention solves this problem by the specified in claim 1 Characteristics.
  • the core of the invention is the design of an injection drill anchor, which both to create a borehole, to seal the borehole, to insert of an injection medium in the mountains and as a load-bearing element of mountain protection serves.
  • the injection drill anchor comprises at least a steel tube that has a smooth cylindrical surface middle longitudinal section and at the ends of outer threaded sections.
  • these threaded sections there is a first threaded section on the one hand with a drill drive and on the other hand in exchange with the drill drive can be coupled with an injection adapter for supplying an injection medium.
  • the second threaded section at the other end of the steel pipe is used for the coupling with an outlet bore for a drill bit the rod head containing the injection medium.
  • On the one with at least A central hose section provided with a transverse bore is an inflation hose fixed in position.
  • the steel pipe can be coupled as required.
  • the first threaded section is used to insert an injection drill anchor coupled with a drill drive.
  • a drill drive Through the drill drive is a Borehole made, at the same time a flushing fluid supplied via the drill drive can be. However, the pressure of the flushing fluid must not be so great that the inflation hose is activated.
  • the injection medium is inserted into the steel pipe via the injection adapter introduced, the locking ball to the mouth of the locking hole in Rod head is shifted in the longitudinal channel.
  • the locking ball seals the Exit area of the longitudinal channel into the rod head.
  • the injection medium thereby occurs through the cross hole in the wall of the steel pipe Inflation hose.
  • This inflates and seals depending on pressure and form-fitting against the wall of the borehole.
  • the pressure of the injection medium so far increased that the locking ball is deformed by the Locking hole is pressed in the rod head, thereby in the interior in the Rod head arrives and thus the path for the injection medium via the Rod head and the outlet holes provided there in the surrounding mountains are released.
  • Due to the pressure-dependent sealing of the inflation hose in the Borehole can inject the injection medium into the rock at high pressure become. This makes the injection area in the surrounding mountains essential increased. This option allows the number of to be set Anchors can be significantly reduced.
  • the injection adapter is removed from the first thread section removed and used for further injections.

A jam in the transport of the Drilling cuttings are avoided.
  • the wall thickness of the deflector sleeve corresponds preferably the wall thickness of the compression sleeves.
  • the openings of the cross holes in the outer surface of the steel tube are according to claim 7 by a tightly enclosing the steel tube elastic sleeve covered.
  • the elasticity of the sleeve is designed so that it only yields at a certain internal pressure in the longitudinal channel of the steel pipe and the injection medium into the inflation hose for pressing the borehole wall releases.
  • the sleeve can for example consist of a Hose section to be formed.
  • the drill drive shows - at least indirectly - according to the characteristics of claim 9 a rotating union for a flushing fluid, such as Water, and a pipe coupling connected to the rotating union.
  • the Pipe coupling comprises two limited in an annular coupling jacket rotatable and radially displaceable against an elastic restoring force Clamping jaws with inner thread segments adapted to the first thread section and locking balls mounted in circumferential recesses.
  • Clamping jaws with inner thread segments adapted to the first thread section and locking balls mounted in circumferential recesses.
  • In the cylindrical inner surface of the clutch jacket are diametrically opposed to each other opposite locking recesses in a circumferential direction intended. The areas of these recesses extend from one radial shoulder first in the circumferential direction and then slightly increasing until they pass into the inner surface.
  • the locking balls are caused by the curve of the recesses pressed radially inwards so that they can then on the Roll along the inner surface of the coupling jacket.
  • the Clamping jaws with the inner thread segments make up the first thread section and if the drilling drive continues to activate, turn it Steel pipe with the drill bit at the end.
  • the drill drive is stopped and turned the pipe coupling back 90 ° until the locking balls under the influence of the elastic restoring force in the recesses arrive and the thread segments detach from the first thread section.
  • the drill drive is no longer connected to the injection drill anchor. Then the rotary union with the pipe coupling from the first thread section are removed.
