Abstract

The anchor (1) i.e. hollow bar anchor, has an outwardly applied or rolled spiral mixer (10) designed as an agitation mixer for a thin bed mixture with an extruded cartridge pipe. Cooling channels and glued ribs cool a drilling bit (4) and roll an adhesive cartridge with a hardening adhesive (12). The thin bed mixture is provided in an anchor length part (13), and instantly supported arches secure the active hardening adhesive. An anchor system is enhanced with additional installation of additional solid rods (20) in the extruded cartridge pipe at a heavy duty anchor (73) for double anchor load. An independent claim is also included for a method for producing a rotatable impact-resistance performed single phase-self drilling-and two phase cartridge-spiral mixer anchor.

Description

  • The invention:
  • The invention relates to a rotationally fixed executed single-phase self-drilling cartridge spiral mixing anchor, with the further function of a mechanical mixer system on the ges. Anchor length in the anchor ring space, as a motion mixer with an extruder effect and a cartridge tube fixed in the hollow bar anchor, for cooling water supply of the drill bit, for cartridges with bracing in the hollow bar anchor, with / without rotary valve, formed with a material-tempering outer mixer spiral, for use in mountain tunnel deep and rock construction, as well as a design as a two-phase cartridge spiral anchor with the pre-chamber method and seconds of pressing the cartridges with bracing for thin bed mixing in the anchor ring space and to support the immediate vault formation, with a quantity of adhesive.
  • The load capacity of both anchor systems, can be doubled according to the geological conditions encountered in the route and tunneling, with the possibility of a subsequent reinforcement, by an introduced additional full stick in the squeezed anchor tube, with a further amount of adhesive.
  • Status of anchor technology:
  • Self-drilling anchors are known with / without an additional adhesive magazine, or as an injection anchor for stabilizing spaces in mining and tunneling, in underground and surface mining, for solidification and securing of retaining walls and in the writings DE 10 2006 002 215.7 .

DE 10 2006 002 215.7 and DE 2005 004 364.2 described in detail in various embodiments, but all are equipped with an internal, axially upstream static functioning mixer system.
  • Depending on the hardness of the rock, the anchoring bore can be produced by wet or dry drilling using these types of composite anchors in various designs. An additional rinsing or suction channel, for removing cuttings from the anchor hole, is required in many designs.
  • After the anchor hole is made with cartridge anchors from an additional inner tube, which serves as an adhesive magazine, the adhesive with the hardener, which is stored in separate tubes, via inner axially axially arranged mechanical connection means and a passively acting static mixer, all after the Auspressvorgang in the anchor tube remain pressed into the anchor ring space between anchor and bore for curing without any rotational movement of the anchor.
  • With the usual simple thread-like deformation of the outer surface of the anchor tube, with a cold-rolled trapezoidal or round profile, the resulting cuttings are no longer promptly carried away, the Bohrvorschub over the tightly dimensioned anchor ring space.
  • With the resulting congestion on the drill bit, the performance, with the unwanted frictional heat, to the destruction of the cutting edges by a solid burning, reduced.
  • Furthermore, with the two small cooling holes in the drill bit, by the later ges. Contents of the adhesive cartridge is pressed after production of the anchor hole, no effective determination of the anchor tube reached in the hole, because with the onset of Static over the static curing hardened process, only one amount of adhesive can get into the anchor ring space, as in the specified curing time of the adhesive cartridge, the mixed and immediately curing Adhesive Teilmenge, the further Nachfluss the invisible adhesive mixture partially prevented.
  • A rapid Auspressvorgang is essentially prevented by the built passive acting, sluggish static mixer and the anchor is thus not in the ges. Length in the anchor hole with the curing process, determines the formation of vaulting, as a part of the squeezed amount of adhesive hardening in the anchor ring space, the extrusion process disturbs, as this takes place without rotational movement of the armature. This deficiency can only be countered with a very slow cartridge, with the subsequent expansion time of several hours for a discount in the drive.
  • In the case of injection drilling anchors, the adhesive and hardener are separately introduced with an adapter via the anchor hollow rod into the anchor ring space and thus the chemical reaction for hardening is initiated via the built-in passively acting static mixer depending on the degree of mixing. With this anchor design, however, is due to the hollow rod, consumed twice the amount of adhesive and when using a Verspannklebers, uneconomical.
  • The mixing of the hardener components is achieved in the known types only with a passively acting static mixer, but in the function of exorbitant increase in the Auspresszeit of several minutes for just under 0.8 liters of adhesive mass, with concomitant, increasing temperature up to about 120 ° C leads.
  • With these time-consuming operations, it is not possible to achieve rapid and immediate vaulting to secure the jacking work, despite all the expensive additional mechanization measures in the route and tunnel driving.
  • Furthermore, the here presented in the writings single-phase anchor systems can be installed only with the rotating drilling process and therefore only time consuming. An economical, rotationally impacting drilling process is not possible, since all in the hollow rod anchor axially arranged items in conjunction with the adhesive magazine flying and thus are not clamped against vibration.
  • The dynamic loadings of the armature and the spatial movements initiated with the rotary impact drilling process can not functionally survive the internal, interlocking construction of the cartridge magazine and render the armature unusable immediately for each use.
  • Anchor systems, which are introduced in the above-mentioned self-drilling execution only rotating with a passive static mixer, are therefore only in soft mountains, d. H. in max. 25% of all encountered rock formations and in harder mountain layers, with the risk of drill bit overheating, the anchor is not suitable.
  • A continuous use of these anchor systems in a fully mechanized propulsion is thus excluded when different mountain formations must be discussed.
  • Another disadvantage is the discharge of cuttings with a catchy, thread-like deformation of the anchor tubes, with the smooth inner wall of the anchor tube is changed so much that this anchor design only for an injection process, with the uneconomical double glue consumption involving the obstructive passively functioning Static mixer is suitable.
  • If the drill cuttings are not carried away quickly enough and the cooling of the drill bit is not supplied with a corresponding corresponding water pressure, depending on the mountain hardness, the anchor cutters in the drill hole may burn with the drill cuttings. The cutters will fall out due to the dangerous overheating and the anchor will be unusable before it is in the ges. Length can be set.
  • Under difficult geological conditions, with the not to be overcome difficulties, from the self-drilling anchor with a passive acting static mixer, therefore a two-phase anchor system with an expensive, useless unprofitable drill bit, if then with a diamond drill, the anchor hole must be beaten additionally.
  • The other distinguishing features of various anchor setting methods that are well known, such as the solid bar anchor with the cartridge setting method and the harmful finger glove effect, the solid bar anchor with filling mortar, and the IBO hollow bar injection drilling anchors, all equipped with a passive static mixer, will be given here not discussed further.
  • Description and function of the invention:
  • 1.) The Single Phase Rotary Impact Self-drilling Cartridge Spiral Mixer.
  • The invention relates to a self-drilling cartridge spiral mixing anchor, as active-acting motion mixer Ankerringraum for Dünnbettvermischung, with a drehschlagfest displaced cartridge tube for cooling water supply of the drill bit and recording the adhesive cartridge in an anchor hollow rod for complete pre-assembly, with only one amount of adhesive.
  • The drill bit can be equipped with a rotary valve instead of channels. With the provided openings or gaps in the rotary valve, the ongoing supply of the drill bit with cooling water or a water-air mixture Wa-Lu during the drilling process, separated from the cartridge magazine, ensured.
  • With the preparation of the rotationally impact-resistant self-drilling cartridge spiral mixing anchor, the peripherally arranged coolant supply is initially only with the abandonment of pressurized water cooling, between the drill bit and protected by a breaker and vibration-free clamped adhesive cartridge with the cartridge tube, and thus an unwanted escape of the adhesive mass during the prevents rotationally boring drilling process from the adhesive cartridge.
  • With the thread-like high pitch, the one or more common externally applied mixer spiral, or mixer caterpillars, is still the fast and supportive, immediate maximum possible removal of cuttings from the Chip chambers of the drill bit, secured to the anchor hole.
  • The lumpy accumulating drill cuttings during the rotary impact drilling process is therefore further shredded in an appropriately designed chip chamber of the drill bit, for further transport via the closely dimensioned anchor ring space of the anchor bore, by an integrated, step-shaped grinder.
  • A firing of the drill bit and thus the dangerous overheating with the melting of the drill bits, which leads to the total failure of the anchor, is thus prevented.
  • The cooling of the drill bit with water, or water-air mixture, is achieved with the anchor tube rotschlagfest displaced cartridge tube, which is installed with a sectional adhesive connection so that the peripherally arranged water channels in the anchor tube or on the cartridge tube, as a stabilizing adhesive surface for impact-resistant connection be used with the anchor hollow rod.
  • When the deepest hole is reached, a large extrusion cross-section is released by changing the direction of rotation, with the rotary valve via friction cams, and with the onset of extrusion pressure from the drill carriage, the break-off device responds.
  • The entire magazinated adhesive is expelled from the cartridge tube, in a few seconds and simultaneously with the mixer spiral, as an active agitation mixer in the ges. Borehole length, for intensive molecular thin bed mixing and for faster curing, mixed mixing.
  • With the welding technically applied single or multi-start actively acting mixer spiral or the mixer caterpillars, the armature hollow rod is tempered with the, additionally introduced in the production of the anchor tube heat and the squeezed adhesive cartridge with the Verspannkleber within the specified reaction time in the annulus between anchor tube and anchor hole, immediately active molecular mixed in the thin bed, as well as with the rotary motion in the ges. Ankerringraum distributed and thus achieved the desired in seconds, stabilizing and supporting vault formation, to secure the propulsion.
  • To improve the adhesive bond between the anchor tube and the mountains in the anchor hole, the mixer spirals act on reversal of the direction of rotation at the same time to fill all existing rock gaps with the tensioning adhesive as an extruder and thus for higher networking with the mountains in the anchor hole and for immediate vaulting, by the molecularly initiated faster thin-bed curing of the cartridge adhesive.
  • With the use of an expansion-adhesive mixture as bracing adhesive, the anchor in the hole is additionally braced by the chemically induced volume displacement in the mountains and thus an early backup in advance for the miners, achieved in the truncated rock layers.
  • To increase the efficiency of this self-drilling cartridge spiral mixing anchor design, as an active motion thin bed mixer, it is also possible that the brazing adhesive is filled as a granular mixture with proportional hardener, without cartridge tubes in the hollow bar anchor.
  • The adhesive granulate is then chemically adjusted so that it liquefies only at a certain, constructive extrusion pressure and in the given time, after the initiation of the chemical reaction and after pressing into the anchor ring space, as a stress adhesive for vault formation, then supportive in the curing phase minimally expanded so that no reduction in the mountain strength arises.
  • Another economical part of this invention is that only the bracing adhesive, a mixture of rock flour with synthetic resin, as a mixture without tube in the hollow bar anchors and only the one or more hardeners are introduced in thin tubes or granules in the anchor hollow rod as a braze, then liquefy under pressure.
  • The squeeze piston is integrated in the squeezing function of the cartridge spiral mixing anchor so that in the end position the return flow from the pressed-out clamping adhesive, with the incipient extruder effect of the spiral mixing anchor as an active motion mixer, is blocked in the anchor hollow rod and also no pressure water from the anchor tube into the anchor ring space can get.
  • The material of the sewer and cartridge tube can be made of steel, aluminum or even a hard PVC, without electrical charge exist.
  • The rotationally impact-resistant self-drilling cartridge spiral mixing anchor described here, as an active motion-thin bed mixer, with the introduced profiled solid rod in the squeezed anchor tube, subsequently with a second amount of adhesive in each phase of the stretch or Tunneling, to become a heavy-duty anchor for a recognized double geological load.
  • 2.) The two-phase cartridge spiral mixing anchor:
  • An advantageous development of the rotationally impact-resistant single-phase self-drilling cartridge spiral mixing anchor, the execution of the two-phase cartridge spiral mixing anchor, with the externally applied mixer spiral as an active motion-thin bed mixer, an economical alternative.
  • This anchor system is used when in a harder mountains, a self-drilling anchor fails and the anchor hole must therefore be additionally introduced with a diamond drill head.
  • For the anchor point is chisel-shaped, for clearing and removal of existing cuttings, with at least one large-sized sharp-edged opening as a sheath mixer parallel to the chisel cutting edge, which also serves to destroy and collect the squeezed cartridge tubes in a pocket formed.
  • Likewise, with a breaker for the anchor transport, the adhesive cartridge secured with the tensioning adhesive in the anchor tip and the piston simultaneously provided with a stop so that when entering the extruder effect of the spiral mixing anchor, as an active moving thin-bed mixer by the opposite direction of rotation after Auspressvorgang as a motion mixer the antechamber, no adhesive mass can flow back into the armature cavity.
  • The pressed out with a piston stress adhesive with the chemical hardener components, flows almost unmixed into a formed with the withdrawn anchor antechamber in the anchor hole and is then with the rotating inserted anchor, as an active movement-thin bed mixer in the anchor ring space, with the mixer spiral simultaneously in the ges. Anchor length mixed and thus supports within seconds, chemical curing.
  • All mechanical connection conditions for use in a carriage magazine, a pressurized water drilling machine, are designed to be compatible with the single phase self-drilling cartridge spiral mixing anchor.
  • Advantageous developments of the invention self-drilling single or two-phase cartridge spiral mixing armature, with the function of a mechanical full-rod spiral and active motion mixer, which are all set only with an amount of adhesive, refer to the associated subject subclaims.
