Definitions

  • the invention relates to a method and a ram boring machine for trenchless laying of pipes 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 DE-C-21 51 259.
  • the self-controlling 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 rip 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
  • a such 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 rope.
  • GB-A-2 085 670 has disclosed a jacking device which is placed on the underground cable with a large radial distance and during its forward movement this the earth surrounding the cable is cleared away.
  • the device has concentrically nested, alternately hydraulically loadable pipes that have gripper arms in the large radial free space between the cable and the interior of these two pipes. The gripper arms alternately press against the cable to prevent the other tube from making an opposite movement while one tube is moving. Without a clamped connection between the tunneling device and the old cable, a forward movement cannot be achieved there.
  • the invention has for its object to provide a method and an apparatus which allow an old pipe already in the ground to be replaced without the aforementioned disadvantages and without having to rip the ground, and to replace a new pipe in a precise or precise manner relocate.
  • this object is achieved in that the ram boring machine for replacing an old pipe lying in the ground is pushed onto the old pipe from a starting pit by a new pipe with a larger diameter, and tightly enclosing the old pipe during its forward movement caused by the impact of a ram drilling ram is guided by this and, at the same time as driving, at least one pull-in pipe concentrically enclosing the old pipe pulls into the ground. Because the ram boring machine runs along the old pipe as it were along a rail or is guided by it, the old pipe that was carefully inserted into the ground when it was laid can be used as a directional guide for the ram boring machine when laying a new pipe.
  • the old pipe can be replaced by a new, larger one without having to destroy the old pipe and its debris remain in the ground. Because the ram boring machine simultaneously pulls a pulling pipe, which concentrically encloses the old pipe and serves as a protective pipe, into the soil, so that after the protective pipe is 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 old pipe thus slides over the old pipe 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 boring machine, 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. Central guidance for the jacking unit results from 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 allows 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 which tapers against the direction of advance, prevents, without destroying the outer surface of the old line, that dirt falling into the earth hole during the advance of the ram boring machine gets into the gap between the guide bore of the ram boring machine and the surface of the old line.
  • 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.
  • An impact 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 pipe 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. as hollow or Ring piston formed.
  • the ram boring machine 1 has at its rear end a connecting piece 8 for attaching 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 pipe 6 with a new pipe, not shown, larger in diameter, the ram boring machine 1 only needs to be pushed onto the free end of the old pipe 6 from a starting pit and then slides over or on the old pipe 6 during the propulsion, which thus as it were Rail takes over the guiding of the ram boring machine 1 in the driving direction 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 introduction 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 striking pistons 15, 16 arranged in a reciprocating manner 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.
