Definitions

  • the invention relates to a device for pre-pressing smaller, no longer accessible pipes over a pre-press section lying underground from an open construction pit, consisting of a guide tube corresponding to the pipe sections to be installed, a milling unit articulated on the guide tube on the feed side, which with an essentially coaxially aligned screw conveyor is rotatably connected, which is surrounded by a coaxially supported within the guide tube, extending between the milling unit and the excavation conveyor tube.
  • the object of the invention is therefore to provide an improved device of the type mentioned in the introduction, which makes it possible to completely or at least to a large extent isolate the conveying path of a pre-pressing device of the type mentioned both in the operating state and in the rest position.
  • the delivery pipe to be partitionable.
  • a partitioning can be done either by means of a device for introducing a swelling agent or else by arranging in the conveyor pipe a diaphragm which is clamped at the edge and extends transversely to the screw axis and has a circular central opening which is essentially adapted to the screw axis diameter and which, on the one hand, approximately supports over half the circumference on the screw axis and on the other hand in the membrane plane on the outer edge of the screw.
  • Pie drilling device to be moved underground from the construction pit 1 consists of a guide tube 2, the outside diameter of which corresponds to the outside diameter of the product pipes 3 to be subsequently laid.
  • the guide tube 2 is articulated to the actual control head 4, the outer diameter of which also corresponds to the outer diameter of the tubes 2 and 3.
  • a milling unit 6 which can be rotated from there via an axis 7 leading to the excavation pit 1.
  • a conveying pipeline 8 which is formed by individual conveying pipe sections 8a, 8b, is arranged in the interior of the guide pipe 2 and the product pipe sections 3, supported on runners or the like.
  • the outside diameter of the delivery pipeline 8 is considerably smaller than the inside diameter of the product pipe sections 3.
  • the latter is mounted coaxially in the control head 4 and is provided with movable seals 10 with limited movement relative to it.
  • the existing between the conveyor pipe 8 and the pipe part 3 installed.Ring space 11 receives drive and control lines and also serves the alignment the control head, for example by means of a laser beam source 13 and a target plate 12 with photoelectric elements.
  • the soil processed with the milling unit 6 is discharged via a screw conveyor 16, which, like the product pipe sections 3 and the delivery pipe sections 8, is divided.
  • a screw conveyor 16 arranged on the axis 15 can be extended in accordance with the progress of the pre-pressing process.
  • the axis ends of the individual screw sections carry interacting coupling parts with which a rotationally fixed connection is possible.
  • the rotational movement initiated by the construction pit 1 can ultimately also reach and drive the milling unit 6 over all parts of the screw conveyor 16.
  • the screw conveyor part adjacent to the milling unit 6 is connected via a coupling 17 to the adjacent coupling part 18 of the subsequent screw section in such a way that the non-rotatable connection is not disturbed, but a slight tilting according to the possibilities of the control cylinder 5 is possible.
  • the foremost section of the screw conveyor 16, which is firmly connected to a milling wheel, is designed such that the screw diameter decreases continuously from the diameter of the milling wheel to the normal diameter of the screw conveyor 16.
  • the pre-pressing device described above works in the usual way. According to the advance caused by pre-pressing, milling loosening of the soil and removal of the latter, shots become of the product pipe 3, the screw conveyor pipe 8 and the screw 15 from the construction pit 1. The joint on adjacent product pipes 3 can then also be sealed in the usual manner with an annular collar 19. After reaching an excavation pit arranged at the other end of the pre-pressing section provided, the control head 4 with guide tube 2 and the milling device 6 can then be removed from the device. Something similar also applies to the other components of the pre-pressing device, although these can also be brought back to the excavation pit 1.
  • a first possibility is to provide a device for introducing a swelling agent, in particular bentonite.
  • the bentonite reservoir can be accommodated in the construction pit 1, where there is also a feed pump.
  • This feed pump can then reach the front area of the screw conveyor and the milling unit from the storage container via a hose line.
  • the corresponding hose line can be conveniently laid between product pipe 3 and delivery pipe 8. This hose opens through the front end of the delivery pipe in the area of the milling device 6 and stabilizes the orbital face.
  • Another possibility of stabilization or partitioning is to provide in the conveyor tube 8 a diaphragm 23 which extends transversely to the screw axis and is firmly clamped at the edge.
  • the attachment of the membrane is extremely simple.
  • the ring flanges 20 and 21 and the membrane 24 have regularly distributed holes 24 for the bolts 22 on their circumferences.
  • the central opening 25 of the membrane 23 has essentially the same diameter as the screw axis 15.
  • the membrane 23 is preferably made of a very elastic rubber-like material, for example neoprene. It is particularly advantageous if the membrane 23 is designed such that its thickness increases continuously from the central opening 25 to the outer edge of the membrane.
  • the central opening 25 (FIG. 3), which is circular when not in use, is deformed in operation, since this central opening only acts on the screw axis 25 on an arc of slightly more than 180.
  • the point of the opening opposite the semicircular configuration of the central opening 25 is supported on the outer edge of the screw conveyor 16. It is understood that this point of support of the central opening 25 at the outer edge of the screw rotates continuously during operation. Since the membrane 23 does not permit any movements in the circumferential direction, the edge parts of the screw conveyor 16 constantly slide against the inner boundary of the membrane central opening 25. To reduce wear here, as shown in FIG. 5, the outer edge of the screw 16 can be at least in the area of the membrane 23 be provided with a bead.
  • This bead can be an integral part of the screw conveyor, but it can also be applied subsequently by build-up welding. It is particularly advantageous if, as shown in FIG. 6, a U-shaped profiled strand section 27 made of plastic is applied to the edge of the screw conveyor 16 in the area of the membrane.
  • the choice of material between membrane 23 and extruded profile 27 is chosen so that the lowest possible frictional resistance and less wear.
  • a plurality of membrane units can also be provided with an axial spacing over the length of the delivery pipe 8.
