Definitions

  • the invention relates to a method and a ram boring machine for trenchless laying of supply lines in the ground by means of a ram boring machine.
  • a pneumatically driven ram boring machine with a percussion tip held in a cylindrical housing and a percussion piston moved to and fro in the housing is known from the German patent specification 21 57 259.
  • the self-steering piston of this device periodically hits the moving tip of the ram. Under the influence of the ramming impacts, the impact tip, which is supported by a compression spring on the device housing, oscillates into the ground and finally pulls the housing when its stroke is exhausted.
  • Such ram boring machines are primarily used to lay supply lines such as water pipes, electrical lines or telephone lines or cables under streets or sidewalks without having to tear open the pavement or sidewalks at the same time.
  • supply lines such as water pipes, electrical lines or telephone lines or cables under streets or sidewalks without having to tear open the pavement or sidewalks at the same time.
  • a ram boring machine can therefore be connected at the rear end to a coupling for fastening a pulling tube; alternatively, a pipe to be laid can also be pulled into the earth channel by means of a pull cable of the ram boring machine.
  • German patent specification 28 24 915 it is known to use such ram boring machines for the destructive replacement of old lines, for example a cast iron pipe or a clay pipe.
  • the percussion tip of the device is provided with blades or percussion knives pointing radially outwards. With the forward movement of the hammer tip of the ram boring machine, the cutting edges blow up the wall of the old pipe, but the debris remains in the ground.
  • the invention has for its object to provide a method and a ram boring machine for performing the method fen, which allow an old supply line already in the ground to be replaced without the above-mentioned disadvantages and without having to tear up the ground, and to lay a new supply line in a precise or precise position.
  • this object is achieved procedurally in that the ram boring machine is guided on an old pipe lying in the ground. Because the ram boring machine thus runs along the old line as if it were a rail or is guided by it, the old line that was carefully inserted into the ground when it was laid can be used as a guiding guide for the ram boring machine when laying a new line.
  • One or - if the ram boring machine is equipped with an appropriate adapter - several new lines can be laid parallel to the old line, possibly at different heights.
  • the old line can be replaced by a new, larger one without the old line having to be destroyed and the debris remaining in the ground. Because the ram boring machine can simultaneously pull a protective pipe enclosing the old pipe into the ground with the advance, so that after the protective pipe has been inserted, the exposed old pipe only needs to be pulled out of the protective pipe and replaced with a new one.
  • a ram boring machine suitable for carrying out the method according to the invention can be provided with a guide bore extending axially through the device housing.
  • the ram boring machine pushed onto the supply line thus slides over the old line running centrally through the device housing and leading the ram boring machine.
  • the percussion piston can be designed as a hollow piston, ie with a central recess corresponding to the guide bore.
  • a hollow piston of large diameter which is adapted to the inside diameter of the housing, two or more correspondingly smaller percussion pistons can thus be used.
  • the guide bore can advantageously be arranged in a guide shoe that can be coupled to the old line.
  • the guide shoe which extends radially to the device housing, surrounds the old pipe with some clearance to the surface of the old pipe, the sliding of the guide hole on the old pipe, which does not hinder the propulsion of the ram drilling device, can be achieved without impairing the guiding of the ram drilling device along the old pipe.
  • the guide piece can connect at least two device housings arranged axially next to one another and have a guide bore surrounding the supply line. In this way, two or more devices can be bundled into one tunneling unit and a number of new lines corresponding to the number of devices can be introduced into the ground in one operation. For the jacking unit there is a central guide due to the old pipe running through the pilot hole. If the guide piece or the adapter has a connecting piece arranged coaxially to the guide bore, a protective tube can be attached to it and thus at the same time a protective tube enclosing the old line can also be drawn into the ground.
  • a coupling socket is advantageously located at the rear end of the device housing.
  • a protective tube can be opened connect this way to the ram boring machine and bring it into the ground as a pull-down pipe in one operation.
  • a thickening of the rear end of the housing advantageously enables the soil to expand, which is particularly useful when new lines with a large diameter are to be laid.
  • a lubricant can be introduced into the gap between the old supply line and the ram boring machine and thus considerably reduce the friction.
  • the mouth of the bore can advantageously be designed as an introduction funnel provided with dirt wipers.
  • the insertion funnel tapering against the direction of advance prevents, without destroying the outer surface of the old pipe, that dirt falling into the earth hole during the driving of the ram boring machine gets into the gap between the pilot hole of the ram boring machine and the surface of the old pipe.
  • the ram boring machine 1 consists of a housing 2 with a self-controlling percussion piston, not shown, and is supplied with compressed air via a line 3.
  • a striking tip 4 is mounted in the front part of the housing 2.
  • Extending through an axial guide bore 5 of the ram boring machine 1 is an old line 6 laid in the ground, which leads the ram boring machine 1 moving forward in the driving direction 7 under the blows of the percussion piston; the percussion piston is provided with a central bore adapted to the guide bore 5, i.e. designed as a hollow or ring piston.
  • the ram boring machine 1 has at its rear end a connecting piece 8 for fastening a protective tube 9, which is thus drawn into the ground as a pulling tube during the machine advance.
  • the ram boring machine 1 To replace the old line 6 with a larger diameter new line, not shown, the ram boring machine 1 only needs to be pushed onto the free end of the old line 6 from a starting pit and then slides over or on the old line 6 during propulsion, which is thus as it were Rail takes the lead of the ram boring machine 1 in the direction of advance 7. Because at the same time Protective tube 9 is drawn into the ground, the old line 6 initially remains in the protective tube 9 and can be pulled out of the protective tube 9 after the insertion of the full length of the protective tube, ie after the ram boring machine 1 has reached the target pit, and exchanged for a new line. However, the protective tube can also serve as a supply line.
  • a conventional, i.e. A ram boring device 101 not provided with an axial guide bore has a radial guide shoe 10 which is provided with a cylindrical receptacle 11 having a guide bore 105 for guiding the ram boring device 101 on the old line 106.
  • the end face 12 of the guide shoe 10 pointing in the direction of advance is designed as a wedge to reduce the ground resistance; for the same reason, the receptacle 11 can be provided with a tip pointing in the direction of advance, similar to the impact tip 4 of the ram boring machine 1.
  • twin impact pistons 15, 16 arranged in two working spaces 13, 14 running parallel to the axial guide bore 205; these move the ram boring machine 201 sliding on the supply line 206 and guided by it in the direction of advance 207.
  • the compressed air is supplied to the percussion pistons 15, 16 via hose connections 17, 18 from a pressure medium source, not shown.
  • the rear end of the device housing 202 consists of a coupling socket 19 receiving a protective tube 209, which also has a jacket thickening 20, ie is larger than the diameter of the device housing 202.
  • the jacket thickening 20 runs in the opposite direction the direction of advance 7, thus conical to the outside and in this way serves to widen the earth channel produced by the ram boring machine 201.
  • the ram boring machine 201 has a conical insertion funnel 22 provided with dirt wipers 21 as the mouth of the axial guide bore 205.
  • at least one lubricant line 23 leads from the rear end to the axial guide bore 205.
