Definitions

  • the present invention relates to a method for renovation of tunnel back surface drainage, being in the tunnel a drainage line is provided below the carriageway level is and in the tunnel wall flush niches are provided that to the drainage lines.
  • the object of the present invention is a method for the rehabilitation of tunnel back surface drainage, in which the drainage lines are not fully exposed Need to become.
  • This task is accomplished by a method of the type mentioned at the beginning Art solved according to the invention in that a core hole attaches diagonally downwards to the drainage line, see above that the core hole in the area of a sink niche in the drainage line that you can go from this sink to one pulls a rope into the drainage line of another sink niche, that you drill a drill pipe into the Introduces the drainage line and drills the drainage line, the drill head being pulled by means of the rope so that it must remain in the drainage line so that the Replaces the drill head with a rock clearing machine and now in the opposite direction broadened the cross section, and that one eventually a new drainage line in the expanded cross section moves in.
  • Drilling systems are known with which several hundred Can drill meters and where the drill pipe has a bending radius allows up to 30 m. (E.g. Vermeer Navigator D16X20A from Vermeer AG in Altendorf, Switzerland.)
  • Vermeer Navigator D16X20A from Vermeer AG in Altendorf, Switzerland.
  • the problem is that these devices are about 5 m long and therefore not at all over an existing sink (usually about one meter is wide) can be brought to the drainage line.
  • a core hole e.g. with a 300 mm diameter
  • the drainage line is usually located about 1 m below the level of the road, the length of the sloping Hole can be about 5 to 7 m (the oblique hole then meets the drainage line at an angle of about 10 °).
  • the diameter of the boring bars is about 50 mm, so that 250 mm remain free in the 300 mm thick core hole. This space is sufficient to allow the drill pipe to be used a bending radius of more than 30 m from the depth of the drainage line can be led to the level of the road. The drill can thus be set up on the road.
  • the cross section is preferably expanded twice in succession, around all pipe remains of the existing drainage line to destroy.
  • FIG. 1 shows a cross section through a tunnel
  • Fig. 2 shows schematically the installation of a Drilling device in the tunnel for performing the invention process
  • Fig. 3 core holes in the area of a strong Curvature of the drainage line.
  • Tunnel 1 is elevated below by lane 2 and two Side strips 3, 4 limited.
  • the drainage line 5 is located below the verge 4, about a meter below the level of the hard shoulder and below the extreme lateral point of the elm.
  • the drainage line 5 is made of filter concrete 6 surrounded.
  • the clearance profile is through a dashed line 7 indicated.
  • the drainage line 5 can be seen from the side.
  • a sink niche 8 can also be seen in this figure.
  • Such Rinsing niches 8 are usually provided in the tunnel every 100 m.
  • the drainage line runs in the area of a flushing niche 8 as an open channel.
  • the drainage line 5 is not always laid in a straight line. To avoid deviations from the target position even before the actual one Being able to determine when work starts is a special one Probe pulled through the existing line and the location of the Measure drainage line 5. This measurement is carried out by Determination of the distance from the receiver to the probe, since depth and Gradients of the drainage line 5 are generally constant. Out the distance and the known height of the drainage line 5 the lateral position can be calculated.
  • the drainage line 5 is drilled horizontally in each case from the sink 8. Depending on the distance the flushing niches 8 and the positional accuracy of the drainage line 5, sections drilled from 150 m to 200 m per drill position (three to four niche distances).
  • the drilling device 11 way too big to put in a sink 8 and from to drill from there horizontally. So you bring an oblique Core bore 9, which in the area of the sink 8 in the Drainage line 5 opens.
  • the minimum bend radius of the drill pipe is about 30 m. With a diameter of the core hole 9 by 300 mm and a diameter of the drill pipe of 50 mm you can easily maintain this bending radius if the length of the core hole is 9 7 m (the drainage line 5 is one meter below the road level). This is in Fig. 2 can be seen schematically.
  • an insertion hole 10 is attached.
  • This insertion hole 10 is used in the section of the drainage line to the right of the flushing niche 8 5 to pull in a new line, whereas with the Drill 11 in the section to the left of the sink 8 is drilled.
  • the core hole 9 and the insertion hole 10 therefore belong to different renovation sections.
  • the existing one Drainage line 5 introduced a pull rope. This is done either manually with a retraction spring or - if the line is not consistent - with a high-pressure water unit (1200 bar, 150 1 / s).
  • the drilling device 11 is positioned and anchored at the edge of the road.
  • the traction cable is attached to the drill head via a swivel attached.
  • the pilot hole in the existing drainage line 5 can, for example, with a 110 mm diameter drill head respectively.
  • a mobile cable winch is used to pull the rope (Tensile force in the order of 50 kN) the drill head and thus the drill pipe in the existing drainage line 5 held. Without the traction cable, the drill head would bend evade the existing drainage line.
  • the overburden filter concrete, pipe remains, fleece .
  • a PEHD pipe with the appropriate diameter is attached to a corresponding suction fan (suction power, for example 9000 m 3 / h), this is introduced into the insertion bore 10 and pulled with the drilling device 11, and the overburden is sucked out with a high air throughput. Sucking takes place simultaneously with the second milling.
