Definitions

  • the invention relates to the use of buried pipes for receiving fluids or power lines.
  • Underground pipes are used for the transmission of fluids or for receiving power lines, in particular power lines, for example
  • High-voltage power lines or data lines used for the transmission of electrical energy or data and laid underground.
  • a power line is primarily understood a line through which energy, for example in the form of electrical energy to supply a consumer or for electronic data transmission or in the form of light energy for optical data transmission is transmitted.
  • the pipe on the one hand, the outer environment of the pipe sufficiently from the interior electrically isolate the tube by the electrical conductivity of the tube material is less than 10 Sm / mm 2 (Siemens meter per square millimeter), for example, for ceramic as an electrical insulator.
  • sufficient heat conduction from the interior of the pipe must be possible, as the thermal conductivity of the pipe material is greater than 1.2 W / (m ⁇ K) (watts per meter and Kelvin).
  • a material with these properties which is often used for buried pipes of the type described above, is, for example, stoneware.
  • Such tubes are typically cylindrical.
  • the buried pipes may receive and divert various fluids, such as water, waste water, gas fluids, such as air, heat pumps or fluids, such as water or natural gas to supply consumers.
  • the underground laying of the pipes can be done by means of a pipe jacking, in which the pipe is pulled or pushed behind a drilling machine.
  • a wall channel which runs parallel to the central longitudinal axis of the tube in the longitudinal direction, form.
  • a fastening element for example in the form of a pin or a screw, for connecting adjacent tubular elements to their frontal elements.
  • the invention has for its object to provide a more flexible and improved use of a buried pipe for receiving fluids or power lines.
  • At least one power cable for transmitting data or electrical energy or a fluid medium in the longitudinal direction of the tube is guided through the wall channel.
  • the fluid medium can serve, for example, for heat removal and, in particular, be a cooling fluid. This can avoid that when transporting electrical energy, in particular high voltage, or of fluids in the interior of the tube resulting high temperatures are discharged through the pipe wall to the outer environment of the pipe or lead to excessive heating of the outside of the pipe adjacent soil.
  • an energy line can be guided through the wall channel in order to transmit data or electrical energy in the longitudinal direction of the tube.
  • a fluid medium can be transported in at least one first wall channel, while an electrical line is guided in at least one second wall channel.
  • a buried fluid pipe in addition to the transmission of electrical energy and / or data by an electrical and / or optical line - for example, a fiber optic cable - is guided in at least one wall channel.
  • a sensor for detecting at least one physical parameter of the pipe or pipe material can be arranged in at least one wall channel.
  • the physical parameter may be, for example, the temperature of the pipe or the pipe wall, moisture or pressure.
  • the wall duct may be used to check the condition of the pipe by advancing a sensor, electrical line and / or optical camera through the duct. For example, a check of the connection or sealing of several pipe elements with each other can be carried out in this way.
  • a plurality of wall channels are provided, which are arranged, for example, distributed uniformly over the circumference of the pipe wall. All wall channels can be used for the same use, for example, in each case an electric line or a fluid medium is guided in all channels. Alternatively, different wall channels may be provided for different uses, for example, in that an electrical line is guided in at least one first wall channel and a fluid medium is transported in at least one second wall channel.
  • protruding fixing bolts or pins may be inserted at their front ends to align when juxtaposed to connect the tubes in the longitudinal direction and center.
  • peg-like sealing elements can be inserted into the front ends of the rolling channels in order to seal the wall channels.
  • the peg-like sealing elements may be part of a seal or a sealing ring, which seals the junction of two frontally juxtaposed tubes outside.
  • tie rods are advanced through the wall channels to retract the tube into the channel.
  • the respective tubes are inserted into the channel and thereby guided on the tension rods.
  • the main channel of the tube and / or the wall channels may be provided with circular, oval or polygonal (polygonal) cross-section.
  • the pipe wall can be made up of several layers. At least two of the layers consist of different materials. For example, a layer of stoneware or concrete may exist to provide stability to the pipe. Another layer may be made of plastic or expanded clay to achieve a protective function. An active function can be achieved be made by a layer (for example, the innermost layer) made of stoneware in conjunction with a glaze.
  • One of the several layers has the at least one or all of the wall channels.
  • this wall channel layer fulfills the function of information transmission or energy transmission by transmitting electrical energy or information via lines which are arranged in the wall channel or the wall channels.
  • the wall channel layer can also serve for heat conduction in the longitudinal direction of the tube by a fluid medium, in particular a cooling liquid is transported through the wall channel or the wall channels. As a result, a thermal insulation of the tube interior relative to the outer environment of the tube, for example, the outer soil, causes.
  • Fig. 1 is a perspective view of a first embodiment
  • Fig. 2 is a perspective view of a second embodiment.
  • the wall 14 forms a hollow cylinder.
  • the wall 14 encloses an inner main channel 16, which extends in the longitudinal direction 18 along the central longitudinal axis of the tube 12.
  • a plurality of evenly distributed over the circumference of the tube wall 14 arranged wall channels 20 are provided.
  • twelve wall channels 20 are provided and in the embodiment of FIG. 2, eight wall channels 20 are present.
  • the dashed lines in Fig. 1 are hidden lines, which illustrate that each of the wall channels 20 extends from an end face 22 of the tube 12 to its opposite end face 24 therethrough.
  • Pipes 12 can be placed against each other and connected to each other to form a correspondingly long pipe.
  • the wall channels 20 of adjacent tubes 12 are brought into coincidence such that in the wall channels 20 guided electrical lines 26 or fluid media 28 are transferred from a tube 12 into the respective adjacent tube.
  • FIG. 1 shows by way of example an electrical line 26 which is arranged in one of the wall channels 20 and projects beyond the end-side end 22.
  • FIG. 2 shows by way of example a fluid received in two of the wall channels 20, which may, for example, be a cooling liquid for heat removal in the longitudinal direction 18. It is also conceivable that in each case one or some of the wall channels 20 an electrical line 26 is guided, while in another or in the other of the wall channels 20, a fluid medium 28 is transported.
  • the embodiment of FIG. 2 differs from the embodiment of FIG. 1 also by a multilayer structure of the tube wall 14. While the tube wall 14 of the first embodiment in FIG. 1 is made exclusively of stoneware, the pipe wall 14 shown in FIG. 2 shows a three-layered construction of an inner layer 30, a middle layer 32 and an outer layer 34.
  • the inner layer 30 may, for example, consist of stoneware provided with a glaze in order to prevent the Tube 12 to protect against an outgoing through the main channel 16 aggressive medium.
  • the middle layer 32 is made of stoneware and has all of the wall channels 20.
  • the outer layer 34 may consist of stoneware, concrete and / or expanded clay.
  • the illustrated layer structure is merely a construction exemplified by way of illustration. Numerous variants of other layer structures are conceivable, in particular with a merely two-layered structure or with a construction of more than three layers. The decisive factor is that all wall channels 20 are arranged in the same layer.
