Definitions

  • a pulling rope can also be suspended in the clearing head, which is guided through the pilot hole previously made.
  • the clearing head with the pulling pipe is pulled through the soil by means of the pull rope and a large winch connected to it.
  • At least three webs can preferably be arranged radially and sharpened in the direction of distribution.
  • the inward collar can consist of notches distributed over the circumference.
  • a welding bead 13 is arranged along the front edge of the draw tube 12, which forms an inward collar and engages over the outward collar 11. In this way, an articulated connection between the clearing head 1 and the pulling tube 12 is created, which can be easily produced on site.
  • the clearing head 1 can be detached from the pulling tube 12 just as easily by grinding the welding bead 13 by means of a suitable grinding device.
  • a ram boring machine 14 is arranged in the inner tube 2 and is supported with a collar 15 at the rear end of the inner tube 2. This ram boring machine 14 can be constructed as described in German Offenlegungsschrift 21 57 259.
  • the outer tube 19 merges via a shoulder 24 into an extension 25 with a radially outwardly directed collar 26.
  • the drawing tube shown consists of an inner steel tube 27, a polyethylene coating 28 and a concrete jacket 29, which serves to protect the coating during the pulling into the ground.
