Definitions

  • the invention relates to a method for replacement in Soil laid pipes according to the preamble of the claim 1 and a device for carrying it out.
  • the invention has for its object a method and to provide a suitable device, with which the replacement of pipes with low tensile loads is possible and unwanted voids cannot occur when changing the pipes.
  • Drill mount In the method according to the invention, a commercially available one Drill mount can be used.
  • the drill carriage comes with one necessary for over-drilling the old pipe Over-drill rods equipped and aligned in the target pit and tense. There is no need for a target pit when the pipe is replaced up to a basement should. Then the old pipe is drilled. By the Solid caking and root coverings are overbored as well as Branches and curves pierced. Subsequently the "drill core" is pulled with the drill carriage.
  • the over-drill rod is released from the drill motor and fixed in the clamping and guiding device of the drill carriage. Then a pull chain is made using a steel cable pulled through the old pipe.
  • the pull chain is on a cover that holds the old pipe in the pull-in pit closes and on a chain suspension attached to the drill motor is arranged, attached.
  • On the other side of the A pulling head with the attached new pipe Now it is in the protection of the over-drill rod the old pipe and the new pipe by means of the drawing head to the target pit through the feed device of the Drill mount pulled. That is, the feed device of the The drill carriage also serves as a pulling device.
  • the old pipe is behind the tensioning and guiding device the drill carriage, the pull chain unhooked from the chain suspension and the separated one Tube piece removed. After that, the drill motor is powered by the Feed device is advanced and the drawing chain is restored hooked into the chain attachment. Then will by moving back the drill motor another piece of pipe drawn.
  • the drill pipe can be removed after unscrewing the drill bit remain in the ground as a protective tube.
  • the drill pipe is preferably made of plastic.
  • FIG. 1 shows a drill carriage 1 with a base frame 2 and a tensioning device 3 with hydraulic cylinder 4 and piston rod 5 and support plates 6 and 6A.
  • a Feed and pull device 7 with hydraulic cylinder 8, Piston rod 9, feed chains 10 and pulleys 11 can a drill motor 12 with hydraulic motor 13 and gear 14 the base frame 2 can be moved back and forth.
  • an adapter 15 for receiving an over-drill rod 20 arranged.
  • a chain suspension 16 with threaded spindle 17, clamping nut 18 and pressure ring 19 attached.
  • a clamping and guiding device 22 is provided for the drill rod 20.
  • a pull chain 26 with a shackle 25 is attached to a tab 24 of a cover 23, shown.
  • On the other side of the cover 23 is over an eyelet 27 and a shackle 30 a pulling head 28 with a Eyelet 29 provided for pulling a new tube 31, wherein at the same time an old pipe 32 through the drill pipe 20 is pulled.
  • FIG. 2 shows the arrangement of the drill carriage 1 in one Target pit 34 excavated in the ground 35, in which the old pipe 32 is to be replaced.
  • the upper part of Figure 2 is the over-drilling of the old pipe 32 shown, while in the lower part of Figure 2 Pull the old pipe 32 and at the same time the pulling of the new tube 31 is shown.
  • some components of the drill carriage are 1 not shown.
  • the drill carriage 1 is in the Target excavation 34 aligned with the help of shims 33 and with the tensioning device 3 with the support plates 6 and 6A clamped in the target pit 34. With the drill bit 21 and the drill pipe 20, the old pipe 32nd drilled.
  • the drill bit 21 is unscrewed and in the target pit 34 the drill pipe 20 detached from the drill motor 12 and in the tensioning and guiding device 22 clamped.
  • the pull chain on the chain suspension 16 and the cover 23 as shown in the lower part of Figure 2, pulling the old pipe 32 while retightening the new one Tube 31 within the drill pipe 20 by method of the drilling motor 3 with the aid of the feed and pulling device 7 done.
  • this can Over-drill rods 20 remain as a protective tube in the soil 35.
