- the invention relates to a displacement machine for creating inaccessible tunnels with a displacement head tapering in the direction of advance.
- Such a displacement machine is, for example, from the catalog for the PATHFINDER / PATRIOT 2000 SYSTEM from Steer-Rite, Ltd. , 1509 Rapids Dr. , Racine, Wl 53404, USA.
- the previously known displacement machine has a displacement head which has an anvil tapering to a point in the direction of advance at its front end in the direction of advance.
- a hydraulically operated ramming device In the interior of the displacement head, a hydraulically operated ramming device cyclically hits the anvil and in this way drives the displacement head in the direction of advance.
- the soil located in the area of the tunnel route is pressed laterally into the surrounding soil by the displacement head and is thus displaced.
- REPLACEMENT BLA ⁇ (RULE 26)
- the object of the invention is to create a displacement machine with which tunnels that cannot be walked on can be driven even in floors with obstacles.
- the tapering area of the displacement head is assigned at least one cutting wheel equipped with removal tools and driven by a drive device, with which the substrate material located in the direction of advance in front of the displacement machine can be cleaved.
- the tapering area of the displacement head is assigned at least one cutting wheel equipped with removal tools and driven by a drive device, the obstacles located in front of the displacement machine in the subsurface are crushed and can thus move laterally into the displacement head tapering in the direction of advance the surrounding earth can be pressed.
- the displacement machine is thus able to penetrate even tough obstacles.
- FIG. 1 shows a longitudinal sectional view of an exemplary embodiment of the displacement machine
- FIG. 2 shows a front view of the cutting wheel of the displacement machine from FIG. 1.
- FIG. 1 shows a longitudinal sectional view of an embodiment of the displacement machine.
- the exemplary embodiment shown in FIG. 1 has a displacement head 1, which comprises a control head 2 and a machine tubing string 3, the length of which is a multiple of the length of the control head 2.
- the machine pipe string comprises a front machine pipe 4 connected to the control head 2, a middle machine pipe 5 attached to it and a further rear machine pipe 6 which is seated on a product pipe 7.
- the product pipes 7 form the cladding of the tunnel to be constructed.
- the diameter of the machine tube strand 3 and the product tubes 7 is approximately half a meter.
- the rear machine tube 6 has a flange 8 at its front end in the direction of advance, with which it is fastened by screws 9 to the tunnel end of the middle machine tube 5.
- the middle machine tube 5 is in turn connected to the front machine tube 4 via a front flange 10 and screws 11.
- the front machine tube 4 has at its tunnel end term a support flange 12 on the control cylinder 13 are pivotally mounted.
- the exemplary embodiment shown in FIG. 1 has three control cylinders 13, of which only one is shown in FIG. 1 for reasons of clarity.
- the control cylinders 13 are arranged in the front machine tube 4 at the same angular distance along the inner wall of the front machine tube 4 and are attached with their front end to a connection 14 on the control head 2.
- the control cylinder 13 serve the
- ERSATZBLAH (REGEL26) To pivot control head 2 with respect to the machine pipe section 3 and thus enable control of the direction of advance of the displacement machine.
- Machine pipe string 3 is made possible by a control joint 15, which is sealed by a joint joint seal 16.
- the control head 2 has a displacement surface 17 which is formed by a rear cone part 18 and a front cone part 19.
- the rear cone part 18 is fastened to a jacket tube 21 of the control head 2 by means of screws 20.
- the rear cone part 18 is inserted from the front into a tubular casing 21 of the control head 2.
- the front cone part 19 is in turn inserted into the rear cone part 18 and fastened to it by screws 22.
- the drive shaft 24 is driven on the tunnel side by a drive unit 26 attached to the rear cone part 18, which has a gear 27 and a drive motor 28 has.
- the cutting wheel 25 can be moved in both directions of rotation by the drive unit 26. At the opposite end of the drive shaft 24, the cutting wheel 25 is attached via screws 29.
- the cutting wheel 25 has a cutting wheel cone 30 which adjoins the front end of the front cone part 19 with respect to the direction of advance and from which the cutting wheel spokes 31 extend in the radial direction.
- the outer ends of the cutting wheel spokes 31 are interconnected by a cutting wheel rim 32. bound. Both the cutting wheel spokes 31 and the cutting wheel rim 32 are provided with removal tools 33.
- a web-shaped cutting wheel tip 34 is provided in the hub area of the cutting wheel 25, with which the soil present in the hub area of the cutting wheel 25 can be loosened and dismantled.
- the cutting wheel 25 also has a larger diameter than the control head 2 and the machine tubing 3, so that the cross section machined by the cutting wheel 25 is larger than the cross section of the machine tubing 3. As a result, the soil is loosened beyond the cross section of the machine tubing string 3 and the displacement of the mined material into the surrounding soil, which is accomplished by the displacement surface 17, is facilitated.
- a liquid can be added to the material broken down by the cutting wheel 25 through nozzles 35, which liquid is supplied to the nozzles 35 via a feed line 36 indicated in FIG. 1.
- the liquid injected into the degraded material is water.
- friction-reducing lubricants can also be added to the liquid.
- the drive shaft 24 is sealed to the outside by seals 37.
- a target plate 38 which serves to to determine the direction and position of the displacement head 1.
- a laser beam emanating from a target laser (not shown in the drawing) and crossing the product tubes 7 is directed onto a target surface 39 of the target plate 38.
- further sensors which record the angle of rotation of the displacement head 1 around its center line and the position angle of the displacement head 1 with respect to the vertical, the exact position and orientation of the displacement head 1 can be determined by an evaluation device.
- FIG. 2 shows a front view of the cutting wheel 25 of the displacement head 1 in FIG. 1.
- the cutting wheel rim 32 which is equipped with removal tools 33 and connects the cutting wheel spokes 31, can be clearly seen.
- the cutting wheel rim 32 prevents obstacles which are not comminuted by the cutting wheel 25 from getting between the cutting wheel spokes 31 and thus blocking the cutting wheel 25.
- the cutting wheel spokes 31 have an angular expansion which increases outwards in the radial direction. This ensures on the one hand that the degradation takes place uniformly over the cross-sectional area.
- the space between the cutting wheel spokes 31 is sufficiently large that the material loosened from the soil lying on the cutting wheel 25 quickly reaches the area of the displacement surface 17 to the rear.
- an output shaft is first excavated, into which the machine part formed by the control head 2 and the front machine tube 4 is then inserted and from there is pressed by a pressing device in the direction of advance.
- the cutting wheel 25 rotates and loosens the soil in front of the control head 2. Due to the forward movement of the control head 2, the loosened material is pressed from the displacement surface 17 into the surrounding earth.
- the middle machine tube 5 is successively attached to the front machine tube 4 and then the rear machine tube 6 to the middle machine tube 5.
- the product tube 7 is finally attached to this, to which further product tubes 7 are in turn attached.
- the pipe string formed by the product pipes 7 is pressed forward by the pressing device.
- the driving force required to drive the displacement head 1 is consequently transmitted through the product pipes 7 from the pressing device located in the outlet shaft to the displacement machine.
- the displacement head 1 can deviate from the intended tunnel route. These deviations can be detected with the aid of the target plate 38 and further position measuring devices and can be corrected by correcting the direction of advance by appropriately pivoting the control head 2 with the aid of the control cylinders 13. If the control head 2 is pivoted with the help of the control cylinders 13 with respect to the machine pipe string 3, the position of the machine pipe string 3 with respect to the product pipes 7 must not change, since otherwise the rear machine pipe 6 does not extend over the entire circumference on the subsequent prevails product tube 7. For one thing, that would have Consequence that a tight connection between the machine pipe string 3 and the product pipe 7 is no longer ensured.
- the operation of the cutting wheel 25 in one direction of rotation leads to a counter-roll movement of the control head 2 and of the machine tube strand 3 in the direction of rotation opposite to the direction of rotation of the cutting wheel 25.
- This counter roll 1 movement can be detected with the aid of the target plate 38 and can be corrected on the one hand by temporarily reversing the direction of rotation of the cutting wheel 25.
- the target plate 38 is expediently arranged in the region of the center line of the machine tube strand 3, so that the laser beam incident on the target surface 39 hits the target surface 39 even when the counter-roller movement has progressed far.
- the displacement head 1 encounters an obstacle during the advance, this is broken up into small parts by the cutting wheel 25, and these are pressed together with the rest of the soil from the displacement surface 17 into the surrounding soil.
- the cutting wheel 25 is also advantageous in the soft ground, since the cutting wheel 25 loosens the soil in front of the displacement machine, so that overall a greater drive speed results.
- the operation of the cutting wheel 25 favors the mixing of the liquid dispensed by the nozzles 35 with the substrate material loosened or dismantled by the cutting wheel 25. This is also due to the uniform and complete mixing of the removed substrate material with that of the nozzles 35 dispensed liquid, the friction forces occurring during the displacement process are reduced, so that the propulsion of the displacement head is easier.
- a further advantage of the exemplary embodiment shown in the drawing is that in this exemplary embodiment no conveying devices are necessary for the removal of the dismantled material inside the machine tube. Consequently, the manufacture and operation of the displacement machine is much simpler than micro tunnel machines, in which the material removed from the cutting wheel is transported through the interior of the machine tube and the tunnel adjoining it. Since the conveying devices to be provided for removal through the interior of the tunnel are omitted in this exemplary embodiment, tunnels of small diameter can be produced much more cost-effectively with this displacement machine. In addition, the space occupied by the conveying devices in conventional micro tunnel machines is now available for other machine elements in the exemplary embodiment shown in FIGS. 1 and 2.
- a conveyor wheel is arranged behind the first cutting wheel, which presses the mined material backwards against the conveying direction and thus supports the displacement of the mined material into the surrounding earth.
