Definitions

  • the invention relates to a method for laying pipes, in the aspect of the two known trenchless laying methods, the controlled horizontal drilling technology (HDD) and the Tunneling technology, especially micro tunnel technology (MT), used in combination and with additional new ones Aspects are added, as well as devices for implementation of the procedure.
  • HDD controlled horizontal drilling technology
  • MT micro tunnel technology
  • the invention is therefore based on the object Propose pipe laying that does not have the disadvantages mentioned having.
  • the embodiment of the invention described below concerns the laying of a product pipe for crossing under of a river 1.
  • the underground is structured as follows: the Both banks of the river consist of sand 2, which is on one Coarse gravel layer 3 rests in which the river bed is formed. Is located under the gravel layer Marble interspersed with marl 4.
  • the pipeline provided runs through all three layers. In the coarse gravel layer cannot maintain borehole support so that the conventional HDD process fails.
  • Pilot drilling is carried out in, as shown in FIGS conventionally by means of the known controlled Horizontal drilling technology (HDD) with a drilling rig 6 along an intended installation route 7 from an entry point 8 to an exit point 9.
  • HDD Horizontal drilling technology
  • a drill head 10 with a relatively small diameter of approx. 250 mm is used with a relatively small HDD device 6 Drilled drill pipe 11.
  • a Product tube 16 introduced.
  • the intended product pipe 16 is prepared in full length (e.g. welded) and lies on trestles 17 in front of the entry point 8.
  • the trestles run on a rail assembly 18 that of the pipe length is accordingly set up before entry point 8.
  • the pusher 15 serves to advance the pipe 16 and is designed for a thrust of approx. 8,000 kN.
  • a microtunnel machine 19 coupled, their energy supply from one mobile energy level 20 takes place at the end of the product tube rides on the rail arrangement 18. Also on this one A mobile is coupled to the side of the product tube Pump arrangement 21 for the rinsing liquid and also one mobile processing system 22 for cleaning the Rinsing liquid.
  • the microtunnel machine 19 is with the drill string of the HDD device connected and then from the puller 13 via the Drill pipe pulled through the ground. By pulling it is exact guidance of the MD machine guaranteed.
  • the connection between micro tunnel machine 19 and the drill string 5 of the HDD device is preferably centric, but can also be eccentric.
  • the product tube 16 lies in its final position along the intended route 7.
  • the product pipe is on the outlet side after disassembly Microtunnel machine and the pulling device through pipe elbows connected to a further line.
  • On the The inlet end is the pipe end after dismantling the devices in the elastic bow lowered and also with a continuing line connected.
  • the laying technique described is almost unlimited applicable. Laying lengths of more than 500m are easy possible. Compared to the well-known HDD technology, it has the The advantage that they can also be used in difficult building sites, e.g. Gravel, stones etc. can be used. The risk of Flushing outbreaks or borehole collapse is practical eliminated.
