Definitions

  • the invention relates to a method and an apparatus for laying at least one Line, especially a pipe or cable line, into the ground.
  • DE 88 09 959 U1 discloses a device for laying lines in the ground.
  • a plow sword of a pipe or cable plow protruding from the surface of the earth is pulled through the ground.
  • the plow sword pulls a displacer over a pull rope or similar arrangement, which creates an underground earth channel during the plowing movement.
  • the pipe to be laid is attached to the back of the displacer and is drawn directly into the earth channel during the plowing movement.
  • the problem with this known device is that when the line is pulled through the earth channel, stones or other hard and in particular sharp-edged objects get into the immediate vicinity of the line and can damage the line.
  • the invention is based on the object, a method and an apparatus for Lay at least one pipe in the ground to indicate where the said Disadvantages in the prior art are eliminated.
  • the invention is based on the consideration in which with the clearing device under the Before the installation of the line to be laid, an earth channel was created Insert protective cable and only then insert the cable through this protective cable.
  • the protective cable protects the cable from the surrounding earth channel when it is laid Soil material. This means that they act in the laying direction (longitudinal direction of the line) Forces (longitudinal forces) on the line are practically independent of the topology and nature of the ground and can be formed by the formation of the protective line on the one hand and by the Retraction movement, on the other hand, are well controlled. The danger of a possible Damage to the cable during installation is significantly reduced.
  • the Protective line also serve as a guide for the line, which even means laying the line along a curvilinear (curved) laying path is made possible.
  • the protective line in particular the protective tube or the protective tube composite after the insertion of the at least to pull a line into the protective line over the installed line section.
  • the Protective cable can be connected to the inside of the cable to be pulled in with a low-friction surface to be provided to frictional forces when pulling the line and the subsequent removal of the protective line between the line and the protective line onto one Reduce minimum.
  • the pipe is pulled into the ground according to the prescribed procedures exposed to much lower tensile forces in the longitudinal direction, which the Pulling in cheaper cables allowed.
  • the protective line can be moved with the clearing device, in particular connected or connectable such that when moving the clearing device Protective line is inserted into the earth channel generated by the clearing device.
  • the line is preferably or is by means of, preferably with the clearing device moving transport device pulled into the protective tube or the protective line or retractable. This means that the retraction movement is independent of the plowing movement of the Reamer.
  • the at least one line can now also be in a further development be inserted into the protective line when the clearing device is at rest relative to the ground.
  • the Transport device comprises in particular a couplable or coupled with the line Transport rope, transport cable, transport chain or a transport rod and one Drive unit.
  • one is located on the surface of the ground located or moving drive device provided for driving the clearing device.
  • the protective cable is removed from the cable after the (last) insertion of the cable Soil removed to be used for another installation process.
  • the Protective cable can also remain in the ground to protect the installed cable. In this case, the process according to the invention is repeated and to extend the line a new protective cable is then pulled into the ground.
  • the clearing device expediently comprises one of the surface of the ground in the Plow sword engaging the ground and a displacer which, in the direction of movement of the Seen clearing device behind the plow sword is pulled.
  • the known device according to FIG. 2 for laying a line 6 in the ground 2 comprises a cable plow 10 movable on the surface 21 of the ground 2 and a Plow sword 4 arranged under the line plow 10 and one with the plow sword 4 coupled displacer 3.
  • the cable plow 10 is in the illustrated embodiment by means of a pull cable (pull cable) 11 from a - not shown - tractor in one with R designated laying direction (pulling direction) can be dragged over the surface 21.
  • This separation of cable plow 10 and, generally during the laying of fixed, tractor enables gentle laying without too much damage to the land. But it is also possible to equip the cable plow 10 itself with a drive.
  • the displacer 3 is the plow sword 4 during a movement of the plow 10th pulled in the laying direction R and creates an underground channel (in the laying direction R extended cavity) 22.
  • the depth of this earth channel 22, its Distance from the surface 21 corresponds to t and is indicated by the Surface 21 showing the top of the displacer 3 set.
  • the displacer 3 and thus the Depth t can be fixed or also adjustable, for example hydraulically.
  • the depth t is typically between approximately 1 m and approximately 2 m, for example between 1.40 m and 1.80 m.
  • the effective cross section of the displacer 3 for displacing the floor is so chosen that the earth channel 22 generated with the displacer 3 is sufficiently large to accommodate the line to be laid 6.
  • the cross section of the displacer 3 usually increases from a front with a smaller cross section towards the back to a smaller To offer resistance when moving through the ground 2.
  • the line 6 is now at a front end with the displacer 3 at the rear Area connected via a detachable connection that can withstand the acting longitudinal forces.
  • the line 6 during the plowing movement of the line plow 10 in the Direction of installation R pulled behind the displacer 3 and directly into that of the displacer 3 generated earth channel 22 moved.
  • the line 6 can thus be practical without digging trenches can be laid directly in the ground 2 in one operation.
  • the plow sword 4 reaches from the surface 21 into the ground 2 beyond the depth t on.
  • the shape of the plow sword 4 is relatively narrow compared to the displacer 3 and also tapers towards the front, as seen in the installation direction R, and also runs in the lower, front area in a kind of lace.
  • the plow sword 4 can easily divide soil 2 and only creates a comparatively narrow trough Movement of the plow 10 in the laying direction R, so that the engagement on the Surface 21 remains limited to the narrow gutter.
  • the plow sword 4 and the Displacers 3 together form a clearing device.
  • the known embodiment shown in FIG. 2 now becomes such modified that the line 6 is not drawn directly into the earth channel 22, but, as in 1, first a protective tube 9 - or more generally a protective line - in the Earth channel 22 is drawn in at depth t.
  • the protective tube 9 according to FIG. preferably detachable, coupled to the rear area of the displacer 3.
  • the displacer 3 can be pivoted in a certain range on the plow sword 4 via a swivel connection attached.
  • the plow sword 4 can now as in the known device according to FIG 2 a line plow 10 be attached.
  • the displacer 3 is again pulled by the plow sword 4 and displaced to create the earth channel 22 in front of and around the ground 2.

  • the cable winch 12 is now during the plowing movement with the Displacer 3 moves with the traction rope 13 is or will be rolled up, so that the line 6 at the plowing movement is not pulled or at least to the protective tube 9 to the rear remains offset.
  • the protective tube 9 is in the earth channel 22, it is actuated the winch 12, the pull rope 13 rolled up with a defined speed profile and thereby the line 6 with a force that can be determined by the cable winch 12 through the protective tube 9 moved in.
  • the line 6 is now when laying before hard and in particular protected sharp objects such as stones or broken glass.
  • the installers, in particular the longitudinal forces on the line 6 are therefore largely independent of the Soil quality of the ground 2.
  • the protective tube 9 as appropriate a desired laying path shaped guide for the line 6 and be provided be designed to be so elastic that the desired line route is sufficient large radii is achieved. This means there is no change in the direction of the route Digging up the ground 2 required more.
  • the protective tube 9 can have a length of several Have meters to a few hundred meters, typically around 200 m. Similar to that Line 6 can also the protective tube 9 from individual pipe sections (individual pipes) corresponding pipe sleeves must be assembled.
