Definitions

  • the invention relates to a device for creating a cavity in a soil from a starting point to a target point along a drilling line for introducing expansion to keep the cavity open with a jacking head at the outer end of which at least one cutting element is provided for loosening the soil, the jacking head having a Receiving space having an opening to which a discharge line is connected, and in which at least one first nozzle is provided for dispensing a liquid for transporting the loosened soil from the receiving space, which is provided so that its dispensing opening is essentially in the direction of the Discharge line is aligned, wherein the advance takes place via a feed device.
  • Such a device is from the DE 4 217 293 C2 known.
  • clay pipes are inserted into the ground from a starting pit using a press frame.
  • the propulsion head has a receiving space for the soil loosened by the cutting edge.
  • a rotary nozzle is arranged in this receiving space, which emits liquid in a jet shape, the orientation of the nozzle in the direction of the clay pipes away from the cutting edge being provided.
  • the soil penetrating into the receiving space is caught by the jets of liquid and moved in the direction of the starting pit through the clay pipes.
  • the head with the nozzles is brought closer to the cutting edge (cohesive) or arranged away from this side (sandy soil).
  • the object of the invention is therefore to overcome the aforementioned disadvantages.
  • At least one second nozzle is provided, which is arranged such that its discharge opening is directed essentially at the soil to be loosened.
  • a further teaching of the invention provides that at least one third nozzle is provided which is arranged in such a way that its discharge opening is directed essentially at an opposite wall of the receiving space. This further improves the crushing and dissolution of the soil.
  • Another teaching of the invention provides that the at least one first, the at least one second and / or the at least one third nozzle can be switched separately. This allows the use of liquid to be optimally adapted to the soil conditions.
  • Another teaching of the invention provides that the expansion involves jacking pipes, tunnel segments, pipe segments or pipelines.
  • At least one nozzle is a full jet nozzle. This is understood to mean a nozzle that emits a bundled jet that essentially appears as a point jet on an obstacle.
  • the energy is optimally delivered selectively. This is advantageous when larger objects are to be specifically crushed or to be moved.
  • the at least one first nozzle is designed as a full jet nozzle. This is advantageous when larger objects are to be crushed or moved in a targeted manner in the rear area of the receiving space of the propulsion head.
  • At least one nozzle is a flat jet nozzle.
  • the at least one second and / or the at least one third nozzle is designed as a flat jet nozzle. This is understood to mean a nozzle which emits a jet which fans out at least in one direction, whereby a broader cutting effect takes place on the object being sprayed. The point energy of the jet is lower, which reduces the depth of penetration into the soil, but at the same time causes a larger-scale comminution.
  • the receiving space is designed to be conical. Alternatively, other shapes can also be provided.
  • the cone is particularly suitable when the loosened soil can be removed by gravity.
  • the receiving space has a section in its wall in which the nozzles are arranged. This makes it possible to provide several nozzles in one area that are aligned differently.
  • Another teaching of the invention provides that at least two nozzles are provided, which are aligned in the direction of the opening, the wall and / or the floor. This improves the crushing and removal of the loosened soil.
  • Another teaching of the invention provides that the jets of liquid released by the nozzles intersect at one point. This improves the crushing and removal of the loosened soil. Furthermore, the energy of the liquid jets is focused in one point.
  • Another teaching of the invention provides that the first nozzle is arranged such that the discharged liquid jet is discharged essentially parallel to the surface of the receiving space. As a result, the cleaning and transport effect is improved with respect to the wall of the loosened soil.
  • the figures show a device 10 with a jacking head 11, at the outer end of which a cutting element 12 is provided for loosening the soil.
  • the jacking head 11 On the opposite side, the jacking head 11 has a connection 13 for an extension 14, which are jacking pipes, tunnel segments, Can act pipe segments or pipelines.
  • the propulsion head 11 has a receiving space 15 which is conical. Alternatively, other shapes such as cylindrical or partially conical are possible.
  • the receiving space 15 is connected to the cutting element 12.
  • the receiving space 15 At its lower end in the conical center, the receiving space 15 has an opening 16 to which a discharge line 17 is connected.
  • a pump 18 can be provided in the discharge line 17 in order to convey the soil and liquid released from the mixture.
  • a recess 20 is provided which extends horizontally in a circular shape over the entire cone.
  • individual depressions can be provided here at different points on the cone.
  • a plurality of first nozzles 21 are provided in the recess 20, which are arranged such that the liquid jet 31 emitted by the nozzle 21 runs essentially parallel to the conical inner surface 19.
  • the nozzles are aligned such that these jets meet at a point 22 in the opening 16.
  • a plurality of second nozzles 23 are provided in the recess 20, which are arranged such that the liquid jet 33 emitted by them is directed towards the cutting element 12.
  • the nozzles 23 are advantageously provided in such a way that the jets 33 meet in an area 24 which is located outside of the propulsion head 11 in the ground.
  • third nozzles 25 are arranged in the recess 20, which are directed essentially at the opposite inner surface 19 of the receiving space 15. They are advantageously provided essentially at right angles so that their rays 35 meet in an area 26. This area is preferably at the level of the transition area 27 between the cutting element 12 and the receiving space 15.
  • the nozzles 21, 23, 25 are connected to a supply line 28 in which a pump 29 is provided.
  • the liquid to be dispensed via the nozzles 21, 23, 25 is supplied via the supply line 28.
  • Fig. 1a shows a plan view of the device 10 according to the invention.
  • the propulsion head 11 with the cutting unit 12 and the receiving space 15 can be seen.
  • the opening 16 is provided in the center of the receiving space 15.
  • the recess 20 with the second nozzles 23 is also shown.
  • Figure 1b shows an alternative view to Fig. 1a with the respective liquid jets 31, 33, 35 emitted by the nozzles 21, 23, 25.
  • the first nozzle 21 emits a liquid jet 31 as a full jet or point jet.
  • the second nozzle 23 emits a surface jet 33.
  • the third nozzle also emits a liquid jet 35, which here is also preferably a surface jet.
  • the cut surfaces BB, CC and DD are shown.
  • the cut surface BB is in the Figures 3a to 3c shown.
  • the cut surface CC is in the Figures 4a to 4c shown and the section plane DD is in the Figures 2a to 2c shown.
  • the cut surface CC is selected such that it shows a section through two nozzles of the second nozzles 23.
  • the cutting plane BB is selected so that it shows a section through two nozzles of the third nozzles 25.
  • the cutting plane BB is selected such that it shows a section through two first nozzles 21.
  • the Figures 2a , 3a and 4a each show the section through the propulsion head 11 according to the invention without the representation of the respective liquid jets 31, 33, 35
  • Figures 2b , 3b , 4b each show the section through the propulsion head 11 according to the invention with the respective liquid jets 31, 33, 35 of the respective cut nozzles.
  • the Figures 2c , 3c , 4c show the respective section through the propulsion head 11 according to the invention with the liquid jets 31, 33, 35 of all nozzles.
  • Fig. 5 shows the device 10 according to the invention when creating a cavity in the ground 30.
  • the cavity (not shown) is opened from a section 32, alternatively also from a starting shaft or the like.
  • the route 32 is provided with an extension 34 (here a tunnel extension).
  • a schematically illustrated press frame 36 with hydraulic cylinder 37 and a feed plate 38 is provided in the section 32.
  • the cavity is opened through an opening 39 in the extension 34.
  • pipe sections 14 are provided, at the front end of which the propulsion head 11 is arranged.
  • the opening 39 is sealed between the extension 34 and the corresponding pipe section 14 via a seal 40.
  • the opening itself takes place according to the known pre-pressing process.
  • the loose rock can only be loosened from the nozzle 21 and conveyed away by the cutting edge 12 in conjunction with a liquid jet 31. If the cohesiveness of the soil increases, the second row of nozzles 23 to improve the process of loosening the soil and / or the third row of nozzles 25 can be switched on in order to simplify the crushing of the soil and the loosening of the soil.
