Definitions

  • the invention relates to a method for the underground insertion of transport pipes of greater length in the ground, in which a media-conducting media or product pipe composed of individual pieces arranged one behind the other from a press pit by means of a hydraulic, pneumatic or mechanical press device in a substantially horizontal direction in the Soil is pressed.
  • Pipes of this type can fulfill a wide range of tasks, for example the transportation of oil, natural gas or the like and of supply and waste water, but they can also be used for the reception and subsequent retraction of cables, be it for electrical power or for telephone lines or for communication lines of any other kind, while at the same time exercising a protective function for such lines.
  • Pipes of the type mentioned are usually either pushed upstream of the pressing device with a drill head or, in the simpler case, provided with a cutting ring at their front end which clears or loosens the soil, so that the cut-off soil can be removed by means of a screw conveyor pointing towards the press pit becomes.
  • a further disadvantage of the known methods is that in the case of pronouncedly thin tubes, their length is limited because, on the one hand, they tend to buckle due to the so-called chest resistance and, on the other hand, they are pretensioned in individual section sections, which can become so large that the pipe may be destroyed.
  • the length that can be introduced in one operation is therefore also limited in pipes with a relatively small cross section.
  • the invention is accordingly based on the object of designing a method of the type mentioned at the outset and an apparatus for carrying out the method in such a way that, despite the use of the known pressing devices, one-piece tubes of greater length can be introduced.
  • auxiliary pipes are introduced into the soil by means of the pressing device, which consist of individual telescoping interlocking sections, the respective output section having a length that corresponds to the length that with economic and optimal conditions according to the previous state the technology is achievable, while the following section has a length that projects beyond the preceding section by that initial length, the media or product pipe engaging in a strand of auxiliary pipes assembled in this way and then in turn the respective last auxiliary pipe section by this initial length towered over.
  • a first auxiliary pipe is first inserted into the soil, which has the above-mentioned initial length and with the introduction of which the power of the pressing device is optimally used. Then the drill head is pulled back through the first auxiliary pipe and the drilling material and the soil are then moved using a screw conveyor or other drilling aids is removed. The second auxiliary pipe section is then introduced into the first auxiliary pipe section, the outer diameter of the second auxiliary pipe section being adapted to the inner diameter of the first auxiliary pipe section such that both auxiliary pipe sections with a sufficient tolerance range so that the second auxiliary tube section can slide easily in the first.
  • the second auxiliary pipe section is approximately twice the length of the first, after it has passed through the first auxiliary pipe section, its front end is inserted into the ground as well as the original first section, so that now after the introduction of the second auxiliary pipe section, approximately twice the pipe length for the product pipe is available.
  • the further auxiliary tube sections are introduced, which always engage in the previously inserted auxiliary tube section and each protrude above the preceding auxiliary tube section by approximately the initial length of the first auxiliary tube section until the desired tube length for the product tube is reached or the ratio of the initial diameter of the first Auxiliary pipe section to the inner diameter of the product pipe limits the length of the product pipe.
  • the inside diameter of the product tube is of course dependent on the medium which is to be conveyed and transported with the product tube or to be absorbed by it.
  • the individual auxiliary pipe sections are also in a manner known per se from their end face out of the press pit acted upon with the pressing device there, like the previous one with respect to the type of introduction, one-piece product pipes which are introduced as a whole into the soil in the manner described.
  • auxiliary pipe sections can remain in the ground after completion of the pipeline; but there is also the possibility of pulling them out again, which is labor-intensive and tedious.
  • the auxiliary pipes remaining in the ground represent a considerable amount of material, which causes corresponding costs, so that the invention is based on the further object of keeping the material accumulation, which is not necessary for the operation of the product pipe itself, small.
  • the individual auxiliary pipe sections have approximately the same length, which corresponds to the length that can be achieved with economical and optimal conditions according to the prior art, the successive auxiliary pipe sections having different diameters, so that the respective preceding auxiliary pipe sections can accommodate the subsequent auxiliary pipe section ends, the adjoining auxiliary pipe section ends only overlapping slightly, namely as far as is necessary for the stability of the Connection is necessary, and in each case a pressure or support tube, which is inserted between the pressure-pressure-side end of the preceding auxiliary tube section and the pressing device, is provided, the outside diameter of which corresponds in each case to the outside diameter of the respective auxiliary tube section to be acted upon and on which the pressing device acts.
  • the pressure or support tubes have a length that corresponds approximately to the length of the individual auxiliary tube sections.
  • auxiliary pipe sections each have the same length, so that the introduction of the auxiliary pipe sections into the ground and their storage is also facilitated.
  • the product pipe can be made "in one piece” and can be driven into the ground over the entire, sometimes considerable, distance in one work step, because only its front section comes into contact with the ground, while the entire rear length is within the auxiliary pipes.
  • Controls for this are known per se, they consist of inclinometers for the vertical and of so-called bound circles for the horizontal, in which the fact is used that the gyro axis which has been initiated once wants to maintain its position.
  • a pressing device consisting of a pressure ring 2 or the like is provided in a so-called press pit 1, which can be operated from a control station 3.
  • the pressure ring 2 can be acted upon in various ways, namely pneumatically, electropneumatically, mechanically, etc., but preferably hydraulically.
  • pressure assemblies 4 preferably arranged in a circle, move on the pressure ring 2 and move the pressure ring 2 in the direction of the arrow 5.
  • the pressure ring 2 in turn acts on auxiliary pipes 11 to 71 (cf. FIG. 3), of which the two first auxiliary pipes 11 and 21 in the illustration according to FIG. 1 have already been introduced into the soil 8.
  • the two auxiliary tubes 11 and 21 telescope into one another, the end of the second auxiliary tube 21 on the press pit side being flush with the end of the first auxiliary tube 11 on the press pit side.
  • next aid pipe 31 according to FIG. 1 is, as shown in FIG. 1, still in a position in which it has not yet reached its end point. Accordingly, with its rear end to the right in FIG. 1, it protrudes beyond the first auxiliary pipe 11 with the section 31a so marked there.
  • Fig. 2 shows this process again in detail and reveals that there are five auxiliary tubes of different lengths are telescopically assembled. These are the outer short auxiliary pipe 11, the subsequent auxiliary pipe 21, the auxiliary pipe 31 and a product pipe 41, which is being retracted in the illustration according to FIG. 2.
  • the length 1 of the press pit 1 is chosen so that the usual pipe lengths, i.e. the length of the individual pieces from which the pipes are assembled, plus the jacking units can be taken up by the press pit.
  • Fig. 3 shows a completed pipe laying below a mudflats 9, which can be completely underrun with the device according to the invention without having to make environmentally harmful upheavals.
  • the water 10 running above the mudflats is protected as well as the marine flora and fauna.
  • FIG. 3 show the large spans in which the arrangement according to the invention and the method according to the invention can be used.
  • the next auxiliary tube always had a length such that, as can be seen from FIG. 3, each auxiliary tube reached from the respective left end in FIG. 3 to the press pit 1.
  • the disadvantages of the resulting material accumulation have been described above.
  • FIG. 5 shows an embodiment for introducing the individual short pipe sections.
  • FIG. 4. pressure pipes 14 are provided which are acted upon by the pressure ring 2 (cf. FIG. 1) in the manner described and thus the bring each last pipe section 101 into its position according to FIG. 4.
  • the pipe sections 81 and 91 which have already been introduced are shown in FIG. 5 in a highly distorted manner compared to their actual dimensions.
