Definitions

  • the invention relates to a method for expanding tunnels or the like. with delay boards.
  • a conventional tunnel expansion is carried out in such a way that expansion arches that conform to the profile are installed approximately 1 m apart in the opened tunnels or tunnels.
  • the spaces between the expansion arches are warped with steel or wood warping boards.
  • the extension arches consist of double-T beams, for example, the ends of the timber can be inserted in a temporarily stable rock or in the protection of a sign in the grooves pointing in the longitudinal direction of the tunnel between the flanges of the beams.
  • the drafting boards can also be inserted as an open draft on the mountain side of the expansion arches, overlapping, but alternately side by side.
  • the timber has to be driven overlapping one another and supported in the overlapping areas from the inside by the expansion arches.
  • the ring-shaped or arch-shaped extension arches can consist of double-T beams or else of V-shaped profiled beams or lattice beams.
  • a warping made of wooden planks is disadvantageous in that the wood rots over time and this can result in undesired settlement. Furthermore, decaying wood in the ground is also not desirable with regard to the groundwater quality.
  • expansion arches are used as double-T girders according to the type described at the outset, and in the lateral grooves lying planks are installed to support the tunnel, the expansion arches are spread by mechanical or hydraulic devices and into the gaps between the base plates of the arches suitable carrier sections installed.
  • the object of the invention is therefore to develop a method for Tunnels or the like to propose that the disadvantages described avoid or reduce.
  • this object is achieved in a method of the type mentioned at the outset in that hollow profiles made of a light, non-rotting material are installed as drafting boards, which are filled with load-bearing light-weight materials in order to produce the required strength and rigidity properties.
  • Distortion boards installed by the method according to the invention can be installed in the usual way between the installation arches.
  • the warping boards according to the invention are connected to one another in the longitudinal direction, for example plugged, outside the expansion arches.
  • plastic tubes or plastic box profiles as hollow profiles, which are filled with hard plastic foam or a similar light stiffening material of sufficient load-bearing capacity.
  • the hollow profiles can also consist of rust-free sheet metal.
  • the hollow profiles are expediently curved approximately in the shape of a cylinder shell on one long side and are designed to be correspondingly complementary on the opposite long side.
  • Such a design of the hollow profiles or the hollow box planks makes it possible to arrange them closely along the extension arches without creating sickle-shaped or wedge-shaped gaps between the individual profiles.
  • the hollow profiles or box girders can also be on one side with spring-like projections and on the opposite Side with complementary grooves.
  • the tongue-like projections and the grooves then interlock and create a good seal against the flushing out of the floor.
  • the hollow profiles or the hollow box planks consist of two U-shaped shells, which enclose a supporting foam plastic body between them at a distance, the legs of which facing one another are connected to one another by rods or tabs which are arranged at a distance from one another .
  • These rods or tabs can bend or buckle under loads by which the shells come closer together when the foam body is pressed together, so that the supports are flexible overall, which is useful, for example, when convergences can occur.
  • the cross section of the hollow profiles can be shaped according to technical requirements. For example, they can be round, rectangular, unicellular or multicellular.
  • the hollow profiles or box girders can be arranged on the mountain side of the expansion arches, in such a way that they are continuously connected or inserted flush with one another in the tail of a shield machine with ring expansion in the longitudinal direction.
  • the hollow profiles are spread immediately after leaving the shield tail and the resulting joint is wedged and / or closed with concrete.
  • This configuration of the method according to the invention gives the draft a flat, full connection to the surrounding mountains, because no flanges or other parts causing gaps protrude. This avoids settlement, or at least reduces it.
  • tunneling is carried out by a full-cut tunnel machine 1, which is equipped with a Spreadable shield tail 2 is provided, which is spread by presses, not shown, in the direction of arrows A, so that it engages non-positively on the mountains.
  • the ring-shaped shield tail 2 thus forms an abutment in the usual way, on which the feed presses can be supported to propel the tunnel machine.
  • the drafting boards 3 of the warp installed in the horizontal direction are installed, in such a way that the respective rear-facing ends of the warping boards 3 are interlocked with the ends of the warping boards of the previous section 4.
  • ring-shaped or arch-shaped extension arches 5 are then installed behind the shield tail 2, which press the delay boards 3 in the area of their connection points against the mountains 6.
  • the expansion arches 5 are built up from segments and can have any cross-sectional shapes.
  • the extension arches consist of double-T beams.
  • the distance between the expansion arches 5 from each other can be about 1 m.
  • the toothed connections 7 of the ends of the warping boards can be designed, for example, as plug connections.
  • the arches consist of arcuate supports 10 assembled from segments
  • these foot plates 11 have the compared to the sole elements 12, which, as can be seen from FIG. 2, may consist, for example, of tubbings, are spread by spreading elements. The gap resulting from the spreading is then closed by the introduction of potting material 13.
  • the sole element 12 forming the sole tubbing can consist, for example, of a prefabricated concrete element.
  • the warping boards 15 consist of round hollow profiles 16 made of plastic, which are filled with a load-bearing foam plastic 17.
  • the plastic tubes 16 have bowl-shaped hollow cylindrical recesses 18, the curvature of which corresponds approximately to the cylinder curvature of the tubes 16, so that the walls of the adjacent warping boards can engage in the hollow cylindrical recesses 18.
  • the expansion arch has an approximately U-shaped profile 19 with legs that run at an acute angle to one another and end regions of the legs that are angled outward.
  • cylindrical shell-shaped indentations are also provided in their central region with grooves 20, into which spring-like webs 21 engage, which are arranged along surface lines on the tubes on the sides opposite the indentations 18.
  • the hollow profiles forming the warping planks consist of box profiles 22 which are filled with a light material filling based on foam plastics.
  • the extension arches consist of double T-beams 23.
  • the box profiles have angular cutouts 24 on an inner corner side, into which web parts 25 of the adjacent warping boards engage.
  • the warping boards consist of hollow plastic profiles 27, which in turn are foamed with a supporting foam plastic 28.
  • the hollow profiles are provided on one side with a convex cylindrical shell-shaped side 29, while the opposite side is complementarily concave.
  • the concave profile sides can, for example, be provided with grooves 30 into which spring-like webs 31 extending on the convex side engage.
  • the expansion arches have a U-shaped profile.
  • FIGS. 9 and 10 basically show profiles corresponding to FIGS. 7 and 8, which, however, have two filled chambers or are of multi-cell design due to longitudinal intermediate walls 32.
  • warping boards which consist of upper and lower flat U-shaped shells 36, 37 made of plastic or sheet metal, which are connected to one another on their legs by tabs 38 arranged at a distance from one another.
  • Lightweight bodies for example foam plastic bodies 39, are held between the shells 36, 37 with sufficient supporting force.
  • Styrofoam or polyurethane for example, can be used as the supporting foam.
  • delay boards are compressed in the direction of arrows B, they are compressed from height h 1 to height h 2.
