Definitions

  • the present invention relates to a method and thereby usable devices for trenchless laying of pipes in the ground.
  • pilot tube drives microtunnelling (microtunnelling, controlled pipe jacking) and controlled horizontal drilling technology (horizontal directional drilling, HDD).
  • pilot tube drives In the pilot tube drives, the installation is carried out in two or three working phases, whereby initially a controlled pilot bore with a relatively small diameter is created and in a further step, this pilot bore is widened to the final diameter and at the same time the product tubes are inserted or retracted. The transfer takes place from a start shaft to a target shaft.
  • bore lengths are generally less than 100 m and the diameter of the pipes to be laid approximately between 100 mm - 1,000 mm.
  • the bore (and thus the pipe installation) is usually rectilinear, ie the control of the pilot hole has the sole Purpose of as straight as possible pipe laying (eg for free fall lines). Due to the process, the pipe strands are successively assembled during the passage of the hole or during installation from individual pipes (jacking pipes, possibly interim pipes or temporarily inserted pipes, product pipes).
  • Another feature of these methods is that these methods are relatively sensitive to certain soil properties (displaceability, water level etc.), so that they are not suitable for example for laying a longer, large-diameter steel pipeline or in rocky soil.
  • MT microtunneling
  • a controlled, sometimes curved hole is usually created from a launch shaft or a launch 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 pit, and the non-zugfest interconnected jacking pipes simultaneously correspond to the product pipes to be laid.
  • bore lengths up to approx. 500 m and borehole diameter of more than 2,000 mm can be achieved.
  • microtunnelling can be used in almost all soil types (loose rock, rock) and in almost all groundwater levels with water pressures (up to 3 bar, possibly more).
  • PE pipes for example, have a very low compressive strength (about 10 N / mm 2 ) and thus severely limit the possible laying range.
  • steel pipes are to be loaded axially high, but must also be installed in the starting area pipe by pipe and thereby welded together. This means several disadvantages for practical use.
  • the welding is great Steel pipes require time-consuming and complicated work (exact alignment and centering required), during their implementation, the actual drilling activity must be interrupted.
  • the welds can not be subjected to a pressure test before laying, which is almost imperative, for example, when installing gas high-pressure lines or oil lines, as a subsequent repair under the obstacle is practically impossible.
  • the relevant piping pressure pipes made of steel, PE etc.
  • pressure pipes made of steel, PE etc.
  • a larger Schutzrohrtour from normal jacking pipes (concrete, polycrete, etc.) is laid, then then retracted or inserted the actual product pipe string becomes.
  • the disadvantages associated with this process are obvious - creation of an actually too large borehole (for the thermowells), costs for remaining in the ground thermowells, additional operation for the subsequent retraction of the product tubing, costs through other equipment such as winches or the like.
  • the third to be mentioned in the context set forth laying method is the controllable horizontal drilling technique (abbreviation "HDD” for Horizontal Directional Drilling).
  • HDD Horizontal Directional Drilling
  • This three-phase process pilot drilling, expansion bore, retraction process
  • tensile-strength pipes made of steel, PE or cast iron, for example.
  • the achievable length of the geometric laying services is greater than that of microtunneling (> 2,000 m), but below that of the achievable pipe diameters (maximum of 1,400 mm).
  • the biggest disadvantage of the HDD is its high sensitivity to the current ground conditions.
  • gravelly, gravelly or stony soils with few cohesive fractions lead to problems almost regularly if boreholes with a relatively large diameter have to be created before the drawing process (> 800 mm).
  • a cementitious material is also introduced into the wellbore to stabilize a gap between the borehole wall and the product tubing. Only when a product tubing having a diameter of less than about 100 mm is to be used, eg a telephone cable, is it not necessary to widen the original wellbore.
  • the present invention is therefore the object of a trenchless laying of properly manufactured and tested, tensile strength pipes with a relatively large diameter (eg, about 800 mm - 1,400 mm) over relatively large laying lengths (eg, about 250 m - 750 m) difficult soil types (such as gravel, gravel, rock, etc.) to make economic conditions possible.
  • a relatively large diameter eg, about 800 mm - 1,400 mm
  • relatively large laying lengths eg, about 250 m - 750 m
  • difficult soil types such as gravel, gravel, rock, etc.
  • a controlled pipe advance under an obstacle is guided from a starting point to a destination point, wherein the borehole is already widened to the final diameter in the first working step.
  • the soil dislodged by the drilling head during the drilling process is hydraulically conveyed out of the borehole.
  • the bit is decoupled from the first jacking tube after reaching the target point, and the first jacking tube is coupled to a connecting tube at the target point.
  • the connecting pipe is connected on the other side to the product pipe string prepared in one piece on the ground surface.
  • This product tubing is installed in the borehole by a tensile force exerted on the zugfest interconnected jacking tubes tensile forces and thereby the jacking pipes are successively pulled to the starting point, while the tensile strength connected to the jacking pipes connecting pipe and the tensile strength connected to the connecting pipe product tubing pulled into the well become.
  • the product tubing is thus laid trenchless.
  • the method according to the invention is a controllable method, with the aid of which (length of the bore) preassembled tubes (diameter eg approx. 800 mm - 1,400 mm) of tensile materials (eg steel, PE, etc.) over a large laying length (about 250 m - 750 m) can be drawn into a curved borehole in almost all soil types and under all groundwater levels, whereby the soil loosened at the drill head is removed and hydraulically removed (ie no soil displacement).
  • the starting point of the hole can be both in an excavation near the terrain surface as well as in a shaft, while the target point is usually in an excavation near the terrain surface.
  • a drilling device consisting inter alia, but not exclusively from the components press device 2, pressure ring 18, drill head 3 and jacking pipes 4 prepared and set up.
  • This is essentially a conventional microtunnelling or pipe driving device ( Fig. 2a ).
  • this drilling device With the help of this drilling device a bore along a predetermined drilling line 5 is driven in accordance with the valid technical rules for controlled pipe jacking, the drill head 3 is acted upon by the pressing device 2 via the pressure ring 18 and the jacking pipes 4 with the required for the drilling pressure force. Furthermore, the jacking pipes 4 stabilize the drilling channel, so that a collapse of the borehole is excluded even in non-stable formations.
  • the measurement of the position of the drill head 3 and the control of the same along the predetermined drilling line 5 are also made according to the common techniques of controlled pipe jacking ( Fig. 2b ).
  • the drill head 3 After the drill head 3 has arrived at the destination point 6 in the excavation 16b, the drill head 3 is separated from the jacking pipes 4. Thereafter, the first jacking pipe 4 is connected via a connecting pipe 8 with the prepared in length of the bore product pipe string 9 tensile strength ( Fig. 2c ).
  • the over-firm connections coupled propulsion pipes 4 are withdrawn from the press device 2 by means of the pull ring 19 - which was interchangeably replaced at the presser 2 against the pressure ring 18 - through the well, at the same time the connecting pipe 8 and the product pipe string 9 in Direction starting point - along the drilling line 5 - to be moved.
  • the individual jacking pipes are successively dismantled and removed from the starting shaft 14.
  • the no longer required connection lines which provide the drill head with electrical and / or hydraulic energy and control signals during the hole bushing and allow the Bohr mecanicungsver- and disposal (conveyor and feed line), separated at the coupling points of the jacking pipes 4 and also off the shaft 14 removed.
  • This process is continued until the connecting pipe 8 and the beginning of the product pipe string 9 have arrived in the starting shaft 14 ( Fig. 2d ).
  • the connecting pipe 8 is separated from the product pipe string 9 and removed from the starting shaft 14.
  • the pressing device 2 and the pull ring 19 are now dismantled and removed from the starting shaft 14.
  • the product pipe string 9 can be connected to the pipeline 12a and 12b and the start shaft 14 can be filled or dismantled ( Fig. 2e ).
  • a second example is the starting point 1 also in a start shaft 14, between the starting point 1 and the destination point 6, however, there is an intermediate shaft 15.
  • This constellation may be required if the distance between the starting point 1 and the destination point 6 is too large to a single hole ( Fig. 3a ).
  • two bores with two separate drilling devices consisting of the components pressing devices 2a and 2b, pressure rings 18a and 18b, drilling heads 3a and 3b and jacking pipes 4a and 4b are now executed simultaneously as described above.
  • the drill heads 3a and 3b are removed from the jacking pipes 4a and 4b.
  • the jacking pipes 4a and 4b are connected to each other by means of additional jacking pipes in the intermediate shaft and secured against buckling by means of a special guide device 13 in the intermediate shaft area.
  • the inner region of the guide device 13 can be filled with lubricant (for example bentonite suspension) in order to reduce the frictional forces during the drawing-in process.
  • the first propulsion pipe 4b is connected via a connecting tube 8 with the prepared in length of the bore product pipe string 9 tensile ( Fig. 3c ).
  • the jacking pipes 4a and 4b which are coupled together by means of tension-resistant connections, are withdrawn through the borehole by the pressing device 2a by means of the draw ring 19, which in the meantime has been replaced by the pressing device 2a against the pressure ring 18a at the same time the connecting pipe 8 and the product pipe string 9 in the direction of starting point - along the drilling line 5 - to be moved.

  • Another preferred application is, for example, when the hole initially with conventional, that is only driven by pressure, but not zugfesten jacking pipes 4.
  • the installation of the pulling device 11 in the jacking pipes 4 can be carried out simultaneously with the installation of the jacking pipes 4 during the hole preparation, or even subsequently, after the drill head 3 has been removed at the destination point 6.
