Definitions

  • the present invention relates to a method and thereby usable devices for trenchless laying of pipes in the ground.
  • EP-A-1 126 130 discloses such a method for trenchless laying of pipes along a predetermined drilling line. This will be a pilot hole and a pipeline is connected to a boring device and the drill string of the pilot bore and the pipeline is introduced by means of a feed device and the pulling of the drill string of the pilot bore. The direction is specified by the drill string.
  • This three-phase process pilot drilling, expansion bore, retraction process
  • tensile-resistant pipes eg made of steel, PE or cast iron.
  • the geometric laying services are over 2,000 m and the achievable pipe diameters at a maximum of about 1,400 mm.
  • controllable horizontal well technology has proven to be a reliable method of laying in suitable soil formations around the world, there are still some environmental, technical and economic disadvantages.
  • rigsite and pipesite For example, large work surfaces (a few thousand square meters) are required on both sides of the obstacle to be traversed (so-called rigsite and pipesite). These areas are not always present especially in ecologically sensitive areas or imply a correspondingly negative impact on the environment when used.
  • MT microtunneling
  • a controlled, sometimes curved bore is usually created from a launch shaft or a starting pit to a target shaft or a target pit.
  • Characteristic of this method is that pilot drilling, Aufweitbohrung and insertion process of the tubes are realized in a single step.
  • This combined operation is basically carried out pushing or pushing out of the starting shaft or the starting excavation pit and the non-zugfest interconnected jacking pipes generally correspond at the same time to be laid product tubes.
  • bore lengths over 500 m and drill hole diameters of more than 2,000 mm can be achieved. Such a procedure is over US 4 121 673 A in that the closest prior art is considered known.
  • a disadvantage of this method is, for example, to be seen in that the jacking pipes, which are usually made of concrete, remain in the bore, which is expensive causes the production of the bore.
  • the use of steel or PE pipes is possible in principle for MT, it is unusual due to the associated technical difficulties.
  • PE pipes have a very low compressive strength and therefore limit the possible laying range directly.
  • steel pipes are to be loaded axially high, but must also be installed in the starting area tube by tube and while being welded together. A use for high-pressure pipelines as oil or gas pipeline is not possible in this way.
  • WO-A-2006/014417 a drilling method for drilling a horizontal, shallow bore as a directional bore to a target pit known.
  • a double-shell, flexible drill string is used.
  • the drill string is drummed and is drilled according to the coil tubing method during the drilling progress.
  • the inner portion of the drill string serves to transmit torque to the downhole drilling tool.
  • the outer part of the drill string serves to guide the bore.
  • a drilling tool is flanged.
  • the drive is via the inner part of the drill string.
  • a feed device is provided above ground. Drilling fluid is provided between the drill string parts.
  • the outer part may be made of polyethylene.
  • the inner part is designed as a steel spring construction around a flexible core.
  • US-A-2002/195255 discloses a drilling apparatus for creating deflected deep wells in which the drill string is flexible and drilled.
  • the drill string is also trimmed according to the coil tubing method during the drilling progress.
  • a drilling device is provided at the end of the drill string.
  • the drilling device is provided in the borehole with a hydraulic drive.
  • the drill string is advanced during drilling until the target position or deposit is reached.
  • coil tubing processes have a drill string that is prepared in one piece, it is not suitable as a product piping. Furthermore, the diameter of the drill string is limited
  • the object of the present invention is to provide a method and a device with which trenchless laying of penstocks can be achieved particularly ecological and economic conditions is possible, and thus the above-mentioned disadvantages are substantially overcome.
  • the one-piece laying of the pipeline which is the later production line, allows a quality check to be carried out in advance, as the pipeline is completed in its entirety before laying. It may be a pressure test and in particular an examination of the shocks such as the envelope as well as a sealing of the shocks are made.
  • the inventive method it is now possible to bring a certified and tested product line cost and quickly.
  • the method according to claim 3 allows a quick and therefore cost-effective installation, since set-up times, as they can make up 50% of the operating time of a drilling and laying plant, for example, when Microtunneling, are almost completely avoided.
  • the advantage of the drilling apparatus according to claim 4 is that it is possible by the cutting ring to avoid damage to the piping in case of necessitating retraction of the tubing string during drilling due to, for example, rock difficulty, lag or diameter subsidence of the wellbore. Furthermore, the preferably separately provided on-site drives of the cutting tool and the cutting ring allow optimal adaptation of the respective propulsion parameters in each direction.
  • An embodiment according to claim 5 allows an optimal arrangement of the cutting ring on the drilling device and an optimal use of the cutting ring for use in an insert for carrying out the inventive Process.
  • Claim 6 shows an advantageous embodiment for achieving the controllability of the drill head.
  • the advantageously integrated crusher according to claim allows a better removal of the cuttings, since the cuttings size homogenized after breaking present for removal.
  • the use of high pressure nozzles according to claim 8 allows a particularly efficient and cost of material and wear costs rock erosion during drilling.
  • the filling of the annulus between the borehole wall and piping causes in addition to the function of keeping open the borehole and a lubrication between the borehole and casing of the pipeline, which can be laid with less effort and thus more cost in the progressive bore the pipeline.
  • a pipeline is laid from a starting point under an obstacle to a destination point, wherein the preparation of the well and the laying of the pre-fabricated on the ground surface in one piece pipeline are carried out in one step, at the front end of the pipeline a controllable boring device, a pusher mounted near the launching point exerts on the pipeline thrust forces, thereby pushing the tubing from the start point to the target point, simultaneously applying the pressure forces required for the boring process, the soil released by the boring device during the drilling operation taken and conveyed via a delivery line in the interior of the pipeline hydraulically from the well and the resulting during the installation process annulus between the pipe and the borehole wall continuously with a suitable Bo is filled.
  • a drilling device 6 is prepared in the starting pit 1 and connected to the pipe 8. At the same time, the pusher 5 is positioned and anchored.
  • the drilling device 6 is essentially a conventional microtunnelling or pipe-driving device ( Fig. 2a ).
  • Piping throughout this application is understood to mean a conduit made of pipes that conducts a whole line, such as gas or oil, even under high pressure conditions, unlike a well supporting conduit such as microtunnelling or jacking pipes or drill pipes.
  • a hole along a predetermined drilling line 7 is driven under an obstacle 9, wherein the drilling device 6 is acted upon by the pusher 5 via the pipe 8 with the force required for the drilling pressure.
  • the measurement of the position of the drilling device 6 and the control of the same along the predetermined drilling line 7 are also carried out according to the common techniques of controlled pipe jacking ( Fig. 2b ).
  • the drilling process along the drilling line 7 is continued until the drilling device 6 has reached the target point 3 in the target excavation 4 ( Fig. 2c ).
  • the drilling device 6 are removed from the pipe 8 and dismantled and removed the pusher 5. If necessary, the pipeline 8 is shortened in the area of the starting excavation 2 ( Fig. 2d ).
