Definitions

  • the present invention relates to a device for expanding a tunnel, comprising a support structure which can be introduced into the tunnel and which is designed as a vault, on the outside of which are mounted units with which the material of the tunnel vault can be removed, which support frame forms an interior that remains free for traffic ,
  • Traffic routes on which goods and persons are transported can often no longer meet the requirements, in particular due to a large growth in traffic volume.
  • the traffic routes must therefore be rehabilitated so that the capacity absorption is improved.
  • older tunnels can not meet the increased requirements due to the increased volume of traffic, so rehabilitation measures often only contain extensions of the tunnel cross section.
  • the double lane can be reduced to just one lane, through this single-track route, the required space can be created so that the reconstruction work can be carried out, the single-track traffic management can still be maintained.
  • the tunnel cross-section devices consist of a support frame, which is designed as a vault. On the outside of this framework various aggregates are attached, with which the material of the tunnel vault can be ablated, also other facilities can be attached, by means of which the removed material can be transported away and the entire tunnel construction can be completed. But this support frame also forms a remaining interior, through which the train traffic can be passed.
  • Such a device shows, for example, the European patent publication EP 2 066 870 B1 .
  • the framework is completely provided for this purpose with an enclosure, thereby can be largely achieved that passing trains are protected from falling rocks, it can also be prevented that the trains, for example, with construction equipment or people who get into the track area, can collide.
  • a passing train is well protected within the supporting frame formed as a vault, especially against stone chipping and against collision with the implements.
  • the trains are not optimally protected when driving through.
  • the object of the present invention is therefore to design a device for expanding a tunnel in such a way that a train passing through the tunnel is optimally protected against rockfall, collisions with implements, persons or the like.
  • the solution of this object is achieved in that in the formed as a vault support structure, a protective device is introduced, which is formed by a further vault and with which the remaining free for traffic interior is separated from the support frame.
  • the further vault is at least partially constructed of wood, the production of this further vault can be made inexpensively and easily.
  • the further vault is formed of vault elements which lined up form the further vault and thereby the protective tunnel is created.
  • the vault elements are designed to be movable, these vault elements can thus be moved in a simple manner with respect to the support frame, so that the protection tunnel formed by these vault elements with respect to the construction site can always be optimally positioned.
  • the individual vault elements in the bottom region of the tunnel can be anchored, whereby stability for these vault elements is achieved, moving these vault elements, for example due to the wind of a passing train can be avoided.
  • a busbar can be mounted within the wider vault, which serves as a catenary for the trains passing through the tunnel.
  • this busbar is also completely separated from the support frame formed as a vault and thus protected persons.
  • a further advantageous embodiment of the invention is that the further vault has a length which is greater than the length of the support frame, so that the further vault dominates the front side of the support frame and projects into the tunnel to be expanded.
  • the end region of the supporting framework is protected, in which the excavation work is carried out on the tunnel arch, be this by break-off units, or by blasting.
  • the further vault also projects beyond the back of the support frame and protrudes into the extended tunnel, thereby also, the rear end portion of the shoring is optimally separated from the traffic route, whereby this is also optimally protected.
  • a further advantageous embodiment of the invention is that the support frame is movable and can each follow the construction progress in the tunnel.
  • the aggregates mounted on the support frame are arranged movable and interchangeable, whereby a great deal of flexibility is made possible on the support frame those units can be mounted, which are most suitable for the particular use within the tunnel.
  • FIG. 1 the tunnel 1 with the original cross-section can be seen, which tunnel 1 is to be renovated and extended to an extended tunnel 2, which is also shown.
  • the protective device 4 is used in the original tunnel 1, which is formed by a further vault 5 and consists of vault elements 6, as will be described in detail later.
  • an interior 7 is formed within the original tunnel 1, which is completely completed laterally to the original tunnel, whereby the trains passing through the tunnel are fully protected against any resulting rockfall or collisions with construction equipment.
  • the support frame 9 can be introduced, on the outside of a variety of aggregates and devices are arranged, which are required to extend the original tunnel 1 to the extended tunnel 2, as described later becomes.
  • FIG. 2 shows the tunnel to be converted 1 with the original cross section in which the protection device 4 is inserted.
  • a bus bar 10 is attached, which serves as the contact line for the tunnel to be traveled trains 11.
  • the mounted inside the protective device 4 busbar 10 is thus completely separated from the working area for the extension of the tunnel 1.
  • this support frame 9 moves in the intermediate space 8, which is between the tunnel 1 and the protective device. 4 is formed.
  • the front part of this support frame 9 consists in particular of a protective cover 12, which covers the area in which the tunnel arch is removed, as will be described later.
  • FIG. 3 is the extended tunnel 2 can be seen, in which the main area of the support frame 9 is located, on the outside of aggregates 13 and other devices 14 are mounted, which are required for the removal and expansion of the tunnel vault and are used.
  • the trains 11 can pass through the tunnel without hindrance and protected by the protective device 4.
  • FIG. 4 is the structure of the protective device 4 forming further arch 5 can be seen.
  • This protective device 4 consists of support sheets 15 which are spaced from each other and are interconnected by planks 16, whereby the further arch 5 is formed.
  • This further vault 5 can be assembled by vault elements 6, a vault element 6 is made FIG. 4 seen.
  • These individual vault elements 6 are preferably constructed of wood, the support bracket 15 may be formed of wood elements, the planks 16 are also made of wood, creating and assembling these individual elements is possible in a simple manner.
  • the other vault can also be constructed of another suitable material.
  • These vault elements 6 are placed on a base 17 which is mounted in the bottom of the tunnel, on this base 17, these vault elements 6 are releasably fixed, but these vault elements 6 can also be slidably mounted on the base 17 in a known, not shown manner.
  • This base 17 also serves as a foundation for the support frame 9 and the rail track 3, the support frame 9 is in a known, also not shown way along the base 17 mounted rails moved.
  • the base 17 can be anchored via anchoring elements 18 at the bottom of the tunnel.
  • FIG. 5 is the support frame 9 can be seen on the outside of various units 13 and other devices 14 are mounted, which are used in a known manner to extend the tunnel.
  • the units 13 are rotatable, pivotable, hinged, height adjustable and movable along rails 19, the tools for processing the tunnel arch can be arranged on telescopic arms, whereby each point of the tunnel arch to be expanded is reached.
  • These units 13 and the other devices 14 can be formed arbitrarily and interchangeably, so that the device for extending a tunnel can be optimally adapted to the existing conditions.
  • the protective cover 12 On the front side 20 of the support frame 9, the protective cover 12 is arranged, this protective cover 12 is, as previously described, retracted into the original tunnel vault, the tunnel vault, which is located above or outside this protective cover 12 can be removed, for example also by blowing up.
  • the protective device 4 is used, which is formed by vault elements 6.
  • This protective device 4 has a length which is greater than the length of the support frame, so that the protective device 4 projects beyond the front side 20 of the support frame 9 and projects into the tunnel to be expanded.
  • the protective device can advantageously project beyond the rear side 21 of the support frame 9 and protrude into the extended tunnel. With this device for extending a tunnel thus all the work on the tunnel can be carried out until the tunnel vault is completely removed, the interior 7 within the protection device 4 is thus completely protected.
  • the protection device 4 can be set up before the expansion work in the tunnel over the entire length of the tunnel.
  • the vault elements 6 must then not be moved during the construction progress.
  • the area of the tunnel can be covered by the protective device, which will soon be processed and which was newly created last.
  • the vault elements 6 can be pushed according to the progress of construction respectively in the tunnel accordingly.
  • the expansion and expansion work within the tunnel can be carried out in an optimal manner, through the fully protected by the protection device 4 interior trains can travel without Steintschisiko risk and without collisions, for example with construction equipment.
  • the device for extending a tunnel in particular for railway tunnels has been described, of course, such a device can also be used for tunnels through which other means of transport are passed.
