Definitions

  • the invention relates to a method for laying a line that consists of a jacket pipe and a product pipe, the casing pipe from a starting pit to to a target pit using a hydraulic pneumatic or mechanical Pressing device is pressed through the soil.
  • the invention further relates to a Pipe with a jacket pipe and a product pipe with an anti-corrosion coating is provided.
  • Jacket pipe / product pipe lines for the transport of liquid or gaseous Substances, such as natural gas, are usually laid when the line is one Crosses railway line, road or waterway.
  • the sealing of the jacket tube ends is further complicated by cable protection tubes, that must be carried in the casing tube.
  • the space between the product pipe and the casing pipe can also be filled with cement become.
  • the invention has for its object, on the one hand, a time-saving and safe Process for laying a casing pipe and a product pipe To create management and on the other hand to provide a generic management, in which the product pipe when laying before mechanical damage and after the installation is protected against corrosion damage.
  • the method according to the invention is characterized in that that segments consisting of a casing pipe and product pipe section manufactured and one by one pre-pressed through the soil, whereby adjacent product pipe sections with each other before each pre-pressing step get connected.
  • the process is time-saving because the pre-pressing of the casing pipe and product pipe section in one phase and not in succession. Because the product line is not must be pulled in later, there is no damage to the anti-corrosion coating. During the pressing process, the jacket tube protects the product tube from mechanical Damage from obstacles.
  • the pressing forces act exclusively on the casing tube.
  • the Product pipe is not loaded, so that damage is avoided.
  • the invention also provides a line with a jacket tube and a product tube which is provided with an anti-corrosion coating.
  • the line is marked through a plurality of segments, which consist of a tubular casing section made of concrete and a product pipe section made of steel, the product pipe sections welded and the jacket pipe sections are non-positively connected.
  • An annular space is preferably formed between the casing pipe section and the product pipe section formed, the thickness of max. 3% of the outside diameter of the product pipe is.
  • An elastic material is advantageously located in the annular space.
  • the annular space between the casing pipe section and the product pipe section is intended to be of fundamental importance Considerations should be kept as small as possible so the outside diameter of the overall system and thus the pressing resistance (negative skin friction) are as small as possible. This requirement also applies to the optimization of the casing tube wall thickness.
  • An advantageous embodiment of the invention is that the first to be installed Segment of the line has a product pipe protrusion at one end.
  • Each additional segment has a product tube protrusion at one end and at the other opposite end of a jacket tube protrusion of substantially the same length on.
  • This design of the segments enables the product pipes in front of each Prepress step can be welded together.
  • the jacket tube overhang enables moving the jacket pipe protrusion until a positive connection is reached at the joints of the jacket pipe sections.
  • the elastic material is preferably connected to the tubular casing section. Between the corrosion protection covering of the product pipe section and the elastic Sliding relative movement of the material is possible. This will avoid that the product pipe is loaded during the advance. The strains that go through the introduction of the propulsive force in the jacket tube will not arise on the Transfer product pipe.
  • the elastic material electrolytic conductivity This will make the cathodic more effective Corrosion protection not impaired.
  • a polyurethane composite foam is preferably used as the elastic material.
  • the elastic material can be designed as a band-shaped endless material, that can be placed in a spiral around the product tube.
  • At least the side of the elastic tube facing the jacket tube is preferred Material liquid-tight.
  • An advantageous embodiment of the invention is that in the tubular section Cable channels and / or channels for a pressing aid are cast in the concrete.
  • Fig. 1 shows a section through a segment, which consists of a tubular casing section 1 Reinforced concrete and a product pipe section 2 is made.
  • a product pipe section is a steel pipe for the transportation of natural gas.
  • the tubular casing section t contains a steel reinforcement, not shown. Between An annular space 3 is formed in the casing tube section 1 and the product tube section 2. whose thickness max. 3% of the outer diameter of the product pipe section 2.
  • an elastic material 4 which is connected to the tubular casing section 1 is connected.
  • a polyurethane composite foam is used as the elastic material used, which is designed as a band-shaped continuous material that spirals around the product pipe can be laid.
  • the elastic material has an electrolytic conductivity in order not to impair the cathodic corrosion protection of the product pipe.
  • the elastic material is on the side facing the tubular casing section Liquid-tight side.
  • cable channels 5 and channels 6 are for a pressing aid, e.g. B. poured concrete.
  • the segments are prefabricated in a production facility and used for installation transported.
  • the max. Segment length depends on the means of transport available from.
  • a product pipe section 2a is from one Surround casing pipe section 1a.
  • the segment 7a faces the excavation pit end up a product pipe protrusion 9a.
  • the pressing forces of a not shown act hydraulic-pneumatic or mechanical pressing device on the segment 7a, and was exclusively on the tubular casing section 1a.
  • the segment 7a can be closed by a closure 10.
  • a closure 10 it is also possible that the bottom is pressed into the product tube open at the front and is removed later.
  • a drill head can be used.
  • a second segment 7b is inserted into the Starting pit 8 introduced.
  • the second segment 7b faces the opposite end the first segment 7a is directed to a product pipe protrusion 9b and to the opposite one End of a substantially equal length of jacket pipe section protrusion 12 on.
  • Fig. 4 it is shown that a third segment 7c is introduced into the starting pit has been. The individual steps of the process are repeated as needed, until the first segment 7a has reached a target pit, not shown.
