Definitions

  • the present invention relates to a device for widening a tunnel, comprising a support structure designed as a vault that can be inserted into the tunnel and on the outside of which units are attached with which the material of the tunnel vault can be removed, which support structure forms an interior space that remains free for traffic , wherein a protective device (4) is introduced into the support structure (9) designed as a vault, which is formed by a further vault (5) and with which the interior space (7) that remains free for traffic is separated from the support structure (9).
  • Traffic routes on which goods and people are transported, can often no longer meet the requirements, in particular resulting from a large increase in traffic volume.
  • the traffic routes must therefore be rehabilitated in order to improve capacity absorption.
  • older tunnels cannot meet the increased requirements due to the increased volume of traffic, so the only remaining rehabilitation measures are often expansions of the tunnel cross-section.
  • the double track can be reduced to just one track.
  • This single-track route can create the necessary space so that the conversion work can be carried out, but the single-track traffic route can still be maintained.
  • devices have been developed for this purpose, which consist of a support structure that is designed as a vault. On the outside of this shoring various aggregates are attached, with which the material of the tunnel vault can be removed, in addition, further devices can be attached, by means of which the removed material can be transported away and the entire tunnel lining can be completed.
  • this supporting structure also forms a remaining one Interior space through which train traffic can pass.
  • Such a device is shown, for example, in the European patent publication EP 2 066 870 B1 .
  • the support frame is completely enclosed for this purpose, which means that passing trains are largely protected from falling rocks, and it is also possible to prevent the trains from colliding with construction equipment or people who get into the track area, for example .
  • This configuration of the device means that a train that is passing through is well protected within the support structure, which is designed as a vault, in particular against falling rocks and against collisions with the work equipment.
  • the support structure which is designed as a vault, in particular against falling rocks and against collisions with the work equipment.
  • the trains are not optimally protected when passing through.
  • the publications DE 689 12 167 T2 and DE 10 2007 014 104 A1 show facilities in which protective covers are arranged in particular in the area of the expansion work.
  • the object of the present invention is therefore to design a device for widening a tunnel in such a way that a train driving through the tunnel is optimally protected against falling rocks, collisions with work equipment, people or the like and that the device is very easy to manufacture.
  • the further vault (5) consists of supporting arches (15) made of wood, which are arranged at a distance from one another and are connected to one another via planks (16) made of wood.
  • an additional protective tunnel is formed, with which the interior, through which the trains during the conversion phase are carried out, is also completely separated from the shoring.
  • the additional arch is made of wood, this additional arch can be produced in a cost-effective and simple manner.
  • the further arch is formed from arch elements, the arch elements are made up of supporting arches and planks, the arch elements being lined up forming the further arch and thereby the protective tunnel is created.
  • Arranging these arch elements in a row makes it easy to set up this protective tunnel, and the use of individual arch elements also allows a high level of flexibility in how the protective tunnel can be constructed, particularly with regard to its length.
  • the arched elements are designed to be movable, these arched elements can thus easily be moved with respect to the support structure, so that the protective tunnel formed by these arched elements can always be optimally positioned with respect to the construction site.
  • the individual arched elements can be anchored in the floor area of the tunnel, whereby stability is achieved for these arched elements. Movement of these arched elements, for example as a result of the wind of a passing train, can thereby be avoided.
  • a conductor rail can be attached within the further vault, which serves as a catenary for the trains passing through the tunnel.
  • this busbar is also completely separated from the support structure designed as an arch, and people are also protected as a result.
  • a further advantageous embodiment of the invention is that the additional arch has a length that is greater than the length of the supporting structure, so that the additional arch protrudes beyond the front side of the supporting structure and into the tunnel to be widened. This protects in particular the end area of the shoring, in which the excavation work on the tunnel vault is carried out, whether by demolition units or by blasting.
  • the other arch also projects beyond the back of the shoring and protrudes into the extended tunnel, thereby also separating the rear end area of the shoring from the traffic route in an optimal manner, whereby it is also optimally protected.
  • a further advantageous embodiment of the invention is that the support structure can be moved and can follow the construction progress in the tunnel.
  • the aggregates attached to the support frame are arranged to be movable and exchangeable, which allows for great flexibility; those aggregates which are most suitable for the respective use within the tunnel can be attached to the support frame.
  • the tunnel 1 can be seen with the original cross section, which tunnel 1 is to be rehabilitated and expanded to an extended tunnel 2, which is also shown.
  • the two existing tracks will be expanded and replaced by a single track 3.
  • the protective device 4 is inserted in the original tunnel 1, which is formed by a further arch 5 and consists of arch elements 6, as will be described later in detail.
  • This protective device 4 forms an interior space 7 within the original tunnel 1, which is completely closed off to the side of the original tunnel, as a result of which the trains passing through the tunnel are fully protected from any rockfall that may occur or from collisions with construction equipment.
  • the shoring 9 can be inserted into the space 8 remaining between the original tunnel 1 and the protective device 4, on the outside of which a wide variety of units and devices are arranged, which are required to expand the original tunnel 1 to the expanded tunnel 2, as will be described later becomes.
  • FIG 2 shows the tunnel 1 to be converted with the original cross section, in which the protective device 4 is used.
  • a conductor rail 10 is attached, which serves as a catenary for the trains 11 to be driven through the tunnel.
  • the busbar 10 mounted within the protective device 4 is thus completely separated from the work area for the extension of the tunnel 1.
  • the front part of the shoring 9 can move into this tunnel 1 with the original cross-section, this shoring 9 moves in the space 8 between the tunnel 1 and the protective device 4 is formed.
  • the front part of this shoring 9 consists in particular of a protective cover 12 covering the area in which the tunnel vault will be excavated, as will be described later.
  • the extended tunnel 2 can be seen, in which the main area of the supporting structure 9 is located, on the outside of which units 13 and other devices 14 are attached, which are required and used for the removal and expansion of the tunnel vault.
  • the trains 11 can safely pass through the tunnel unhindered and protected by the protective device 4.
  • This protective device 4 consists of supporting arches 15, which are arranged at a distance from one another and are connected to one another via planks 16, as a result of which the further vault 5 is formed.
  • This further vault 5 can be composed of vault elements 6, a vault element 6 is made figure 4 apparent.
  • These individual arch elements 6 are preferably made of wood, the supporting arches 15 can be made of wooden elements, the planks 16 are also made of wood, the creation and assembly of these individual elements is possible in a simple manner.
  • the further vault can also be constructed from another suitable material.
  • These arch elements 6 are placed on a base 17, which is attached to the floor of the tunnel.
  • arch elements 6 can be detachably fixed on this base 17, but these arch elements 6 can also be slidably placed on the base 17 in a known manner that is not shown.
  • This base 17 also serves as a foundation for the supporting frame 9 and the rail track 3, the supporting frame 9 can be moved in a known manner, also not shown, along rails mounted on the base 17.
  • the base 17 can be anchored via anchoring elements 18 at the bottom of the tunnel.
  • the support structure 9 can be seen, on the outside of which various units 13 and other devices 14 are attached, which are used in a known manner to expand the tunnel.
  • the units 13 can be rotated, pivoted, folded, adjusted in height and moved along rails 19, the tools for processing the tunnel vault can be arranged on telescopic arms, whereby every point of the tunnel vault to be expanded can be reached.
  • These aggregates 13 and the other devices 14 can be designed in any desired and interchangeable manner, so that the device for widening a tunnel can be optimally adapted to the prevailing conditions.
  • the protective cover 12 is arranged on the front side 20 of the supporting structure 9. As has already been described above, this protective cover 12 is 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 blasting.
  • the protective device 4 which is formed by arched elements 6 , is inserted inside the arched support structure 9 .
  • This protective device 4 has a length that is greater than the length of the supporting structure, so that the protective device 4 protrudes beyond the front side 20 of the supporting structure 9 and projects into the tunnel to be widened.
  • the protective device can also protrude beyond the rear side 21 of the support structure 9 and protrude into the widened tunnel. With this device for widening a tunnel, all the work that needs to be done on the tunnel can be carried out until the tunnel vault has been completely expanded, and the interior space 7 within the protective device 4 is thus completely protected.
  • the protective device 4 can be erected over the entire length of the tunnel before starting the lining work in the tunnel.
  • the arch elements 6 then do not have to be moved during the construction progress.
  • the area of the tunnel that will be processed soon and which was newly created last can be covered by the protective device.
  • the arch elements 6 can be pushed further in the tunnel.
  • the expansion and expansion work within the tunnel can be carried out in an optimal manner.
  • the trains can drive through the interior space, which is completely protected by the protective device 4, without risk of falling rocks and without risk of collisions with construction machinery, for example.
  • the device for widening a tunnel has been described in particular for railway tunnels, of course such a device can also be used for tunnels through which other means of transport are guided.
