Definitions

  • the invention relates to a device for injecting mortar into a borehole with the Features of the preamble of claim 1.
  • Such devices become Set so-called injection anchors used.
  • Injection anchors are common rod-shaped components such as threaded rods, Dywidag rods or special anchors, which are inserted into a larger bore and with anchored in mortar or the like.
  • For injecting the mortar especially in A deep borehole can be used to inject an injection tube Spreading device for the mortar, for example a so-called squeeze gun and the mortar emerges at the front end.
  • the injection tube is up in put the area of a bottom of the borehole into the borehole and inject the mortar, i.e. brought into the borehole.
  • a bubble-free filling of the borehole with mortar is, however, good Anchorage of the injection anchor with high pull-out values required.
  • the invention is therefore based on the object of a device for injecting To propose mortar in a borehole, which is a bubble-free injection of the mortar into it Drill hole allows.
  • the device according to the invention has an injection tube with a laterally protruding one Covenant on.
  • the all-round trained waistband should be a smaller one Have diameter than the borehole, so that the device in the Drilled hole and can be pulled out again.
  • To inject the The device is mortar into the borehole in the area of the bottom of the borehole and the mortar is inserted through the injection pipe in the area in front of the collar Well injected.
  • the mortar fills the borehole between the bottom of the borehole and the Collar of the device, the collar preventing mortar towards one Drill hole flows out.
  • the device according to the invention has the advantage that it is bubble-free Backfilling of a deep borehole with mortar is also possible.
  • the injection tube of the The device according to the invention can, but need not, have a circular cross section to have. It is also common, but not mandatory, that the Injection tube has an invariable cross section over its length.
  • the collar is in the region of the front end of the Injection tube attached.
  • Another embodiment of the invention sees one on the injection tube slidable waistband.
  • the injected mortar shifts the Collar on the injection tube, the injection tube therefore needs when injecting the Mortar must not be moved back towards the mouth of the borehole.
  • the collar is detachably attached to the injection tube. On this allows the collar to adapt to different borehole diameters be replaced.
  • One embodiment of the invention provides for the collar to be designed in the form of a spout, which is put on the injection tube.
  • the invention is described below using an exemplary embodiment shown in the drawing explained in more detail.
  • the single figure shows a device according to the invention in side view.
  • the device 10 according to the invention shown in the drawing for injecting Mortar in a borehole has an injection pipe 12, which is located on a rear Extended in one piece to a push-on sleeve 14. With the push-on sleeve 14 that is Injection tube 12 clamped on a mortar discharge nozzle 16 of an otherwise not shown, known mortar applicator attached. On a front End 18 is a spout 20 placed on the injection tube 12, which has a circular disc Bund 22 has. The collar 22 is located in a radial plane Injection tube 12, i.e. it protrudes laterally from the injection tube 12.
  • the injection tube 12 For injecting mortar into a particularly deep borehole 24 in a masonry 26, the injection tube 12 is inserted into the borehole 24 until it is at one Borehole bottom 26 is seated or in any case close to the bottom of the borehole. Subsequently, mortar 28, for example a synthetic resin mortar, is not used shown by the dispensing nozzle 16 and the injection tube 12 in the borehole 24 introduced. The mortar 28 emerges from the front end 18 Injection tube 12 and fills the space between the bottom of the borehole and the collar 22 of the device 10 according to the invention in the borehole 24. The hole 24 injected mortar 28 builds up pressure that is complete and bubble-free Filling the borehole 24 between the collar 22 and the bottom of the borehole 26 causes.
  • mortar 28 for example a synthetic resin mortar
  • the pressure of the mortar causes the expanding space between the collar 22 of the device 10 and the bottom of the borehole 26 in the borehole 24 always completely and bubble-free with the Mortar 28 is filled, the amount of which increases continuously through the injection.
  • the borehole 24 can be drilled from the bottom of the borehole 26 to the mouth of the borehole 30 Fill completely and without bubbles with mortar 28.
  • the grommet 20 with the collar 22 is immovable to the front by clamping force End 18 of the injection tube 12 attached. This way moves at Inject the mortar 28 into the entire device 10 including the injection tube 12 with the collar 22 pushed back by the injected mortar 28 back in the direction of Borehole mouth 30.
  • the spout 20 is withdrawn from the injection tube 12 and it becomes a other nozzle 20 attached to the front end 18 of the injection tube 12, the Collar 22 has a different diameter.
  • the waistband 22 should be approximately one up to two millimeters smaller in diameter than the borehole 24 so that the Device 10 is freely movable in the borehole 24.
  • An annular gap between the collar 22 and a wall of the borehole 24 is so small that one at best negligible amount of the injected mortar 28 passes through the annular gap, and that there is sufficient pressure build-up in the mortar 28.
  • the spout 20 can be moved against the injection pipe against frictional force 12 put on.
  • the spout 20, which is at the beginning of the injection of the mortar 28 front end 18 of the injection tube 12 is from the injected mortar 28 the injection tube 12 moved back towards the borehole mouth 30 without that the injection tube 12 are moved in the direction out of the borehole 24 got to.
  • the injection tube 12 can thereby until the complete filling of the Borehole 24 with mortar 28 remain stationary in borehole 24 and is only after Completion of the injection of the mortar 28 is withdrawn from the borehole 24.
  • the squeeze gun not shown, is required during the injection of the mortar 28 not to be moved.
