Definitions

  • the invention relates to a method for expanding a tunnel from an old light room to a new light room.
  • the invention further relates to a device for carrying out the method.
  • the railways of Europe operate in large parts up to the present day railway lines, whose routing fundamentals originate from the founding years of rail transport in the 19th century.
  • the railway lines are integrated into the nature and the settlement structure in such a way that the large engineering structures such as bridges and tunnels can be renewed in most cases only in the existing routing.
  • 380 of the 600 tunnels operated by Deutsche Bahn railways date back to the early days of rail transport.
  • the railway tunnels are inspected by routine inspections of tunnel professionals in specified cycles and by appropriate Measures kept in a safe operating condition.
  • DE 39 42 013 C2 a tunnel boring machine for expanding a stud is described, wherein these two by means of a feed device relative to each other displaceable parts, a certain attack in the tunnel to be extended fixture, a rotatably mounted, drivable extension drill head and at least one extendable and retractable support supporting device has for the inner part and the drill head on the outer part and the bracing arranged directly on the inner part and the supporting device and the bracing device are connected to the inner part ( DE 39 42 013 C2 ).
  • the invention has for its object to provide a method for expanding a tunnel from a Altlichtraum on a Neulichtraum as well as an apparatus for performing the method in which a complete block during expansion work can be avoided.
  • This object is achieved in a method for expanding a tunnel from an old light room to a new light room according to the invention with the features of claim 1.
  • the object of the invention is achieved with a device for carrying out the method according to the invention with the features of claim 8.
  • the movable enclosure makes it possible to effectively protect railway operations at every point in the tunnel from the work of tunneling, thus ensuring 24-hour operation of the tunnel construction site. It must be constructed in such a way that all essential work of tunneling is possible from it. These include the demolition of the existing masonry, the excavation work of the rear packing and the eruption of the mountains by dredging, chiselling or blowing.
  • the enclosure is at the same time working tool for reinforcement and shotcrete work in which the required equipment is mounted on radial and longitudinally displaceable guides and thus ensure the accessibility of each operating point.
  • the old masonry support ring secures the tunnel. Behind the enclosure, the new shotcrete shell with anchors serves to secure the mountains until the permanent inner shell of sheared concrete is installed.
  • the enclosure must be designed so that it reliably keeps clear the clearance required for train traffic. This must be ensured even in the case of extraordinary loads such as subsequent breakage or improper operation of the device, which despite all care can happen. For this it is necessary that enclosure and superstructure for the track lying in the middle form a unit. In the case of a displacement of the enclosure, the operating track moves with, so that the required clearance is always available.
  • the workflow is as follows.
  • the track is laid in the center of the tunnel and braced by the strip foundations with back anchoring to a cofferdam.
  • the expanded area behind the enclosure is provided with a massive impact protection to protect the railway operations.
  • the protective housing is mounted in front of the tunnel portal and moved on with the driving position.
  • the tunneling area will be located in the middle of the enclosure, which is at least 15 meters long, so that the protection of the railway operation is ensured by a platform at least 6 m long in every direction and on the side of the enclosure.
  • the system anchorage is carried out with top plates and the tunnel shell is cut by saw cuts into defined lengths of 1.0 m or 2.0 m.
  • the Outbreak and securing the cavity to be made with reinforced shotcrete.
  • a 35 cm thick tunnel inner shell made of waterproof concrete is concreted using a formwork carriage on locally prepared foundation beams, which together with the integrated cable duct later serves as a walkway.
  • the expansion can be carried out with prefabricated reinforced concrete components (tubbing) or with shotcrete lining or by means of combinations of these methods in the area of the enclosure.
  • the inventive method allows the production of a new, modern tunnel cross-section with, for example, 52 m 2 cross-sectional area above the rail top.
  • the inner radius can, for example, be increased from 4.0 m in the actual state to a planned radius of 4.97 m.
  • All current building specifications for tunnel profiles can be considered and the tunnels are available for all new developments without restriction.
  • the clearance gauge GC together with the compliance with the requirements of the danger zone and the security room, even offers the option of track electrification.
  • Fig. 1 shows a side view of an embodiment of an apparatus according to the invention for carrying out the method according to the invention, with this embodiment for expanding a railway tunnel 1 as a tunnel with two control tracks as regular traffic routes in a propulsion direction 2 still originating from the 19th century Altlichtraum 3 to one according to the latest regulations to be reshaped Neulichtraum 4 is widening with respect to the Altlichtraum 3 larger gauge space.
  • a single makeshift track was created as Behelfs Industriessweg after removal of the two control tracks in the middle of the tunnel 1, so that in each case a working space remains on both sides of the makeshift track.
  • the temporary track is set up so that limited temporary traffic in the tunnel 1 is still possible.
  • Fig. 1 can be seen that in a direction indicated by an arrow propulsion direction 2 front part of the Altlichtraum 3 is present with the originally narrow cross-section of the tunnel 1, which widen in the propulsion direction 2 rear Neulichtraum 4 with an enlarged cross-section is.
  • a housing 6, which completely surrounds the temporary track in the working area 5 is arranged in a working area 5.
  • the work area 5 is sealed at the front in the direction of advance 2 side of the housing 6 with a front dust wall 7.
  • a front Stabilisatorplattenpositionieran Aunt to the housing 6 are mounted in a forward section 8, with which front stabilizer plates, as shown here, a front ridge stabilizer plate 10, against which usually made of quarrystone masonry and a Backfill existing Alttunnelwand 11 is pressable.
  • the flow section 8 is closed on its side facing away from the front side dust wall 7 side of a protective wall 12.
  • propulsion presses 29 that are supported on the back side of already set elemental segmentation elements 27 and ridge segmentation elements 28 are arranged in the direction of propulsion 2 as components of a propulsion system, in order to provide an advance in FIG Fig. 1 to produce shown arrangement in the advancing direction 2.
  • Fig. 2 shows the arrangement according to Fig. 1 in the region of the forward section 8 with a view in the longitudinal direction of the tunnel 1 against the advancing direction 2.
  • Fig. 2 It can be seen that in the tunnel 1 in the middle of the two rails 30, 31 formed Behelfsgleis 32 is located, in each case a working space 33, 34 is provided by the removal of two originally present in the tunnel two control tracks on both sides of the temporary track 32 , Both sides of the rails 30, 31 are Work rails 35, 36 are arranged, on which the housing 6 is mounted rolling.
