Definitions

  • the invention relates to a method for rehabilitating consisting of a ballast layer and from underlying soil layers multi-layer substructure consisting of sleepers and rails tracks on rail lines.
  • the railways consist of a multi-layered substructure on which the tracks are located.
  • the tracks consist of the sleepers and the rails.
  • the multi-layer substructure initially consists of soil layers. These are, in particular, a protective cover layer, an antifreeze layer and possibly further layers. On these soil layers is then a gravel layer. This serves to receive the track.
  • the above-described multi-layer substructure must be rehabilitated from time to time.
  • the track itself is not necessarily always renewed. It can also be renewed or partially renewed at the same time.
  • the known methods for refurbishing this multi-layer substructure using appropriate machines are technically complex and inflexible, especially with regard to the machine equipment.
  • the object of the invention is therefore to provide an improved method for rehabilitating the multilayer substructure consisting of a ballast layer as well as underlying ground layers of railroad tracks consisting of sleepers and rails.
  • an improved method for rehabilitating existing of a ballast layer and underlying soil layers of multi-layer substructure consisting of sleepers and rails tracks on railways created, which is characterized by its simple technical realization using flexible working car with appropriate machinery.
  • the core idea of the rehabilitation process according to the invention is that between the work car to remove the track and a separate, further work car for reinstalling the same or new or partially renewed track additional, separate work cars are. This or these intermediate work cars take on very specific tasks for the rehabilitation of the substructure and are therefore flexible because of their separate training with respect to the other work cars.
  • An essential aspect is that all work cars are continuously moved forward during the work process.
  • the soil layer below the ballast is integrated with regard to its rehabilitation in the continuous remediation process.
  • the soil layer to be rehabilitated is removed by means of a lifting unit, which is located on a separate work car between the work car for track removal and the work car for track installation.
  • the core idea thus lies in the continuous expansion of the soil layer with the track dismantled as part of a continuous process of all sub-operations or complete operations.
  • the invention is characterized by a continuous rehabilitation of the railway line with renewal or processing of all or individual soil layers in a continuous process, including the replacement of the existing track or a completely new or partially renovated track.
  • the particular advantage of the rehabilitation process according to the invention with the special expansion of the soil layer by means of a separate work car is in the workplace height with a developed track with complete accessibility of the track.
  • the development according to claim 2 proposes a yokewise track renewal.
  • the basic idea is that first the track is split into a short yoke and long jetties. The first work car then picks up the yokes. By means of a transport device, the yokes are then fed to the second work car and reinstalled by this after the renovation of the substructure.
  • the transport device for transporting the yokes from the first work cart to the second work cart is preferably a gantry crane, which can be moved longitudinally on the work cart on rails. Other transport facilities are conceivable. It is also conceivable to completely renew the yokes or at least partially renew the developed, existing yokes. For this purpose, suitable work car with the storage and transport of the appropriate material.
  • the development according to claim 4 proposes that the ballast layer is excavated in the flow before removing the track. This purpose is served by a corresponding machine, which is not part of the above-described work car. The removal of the old gravel layer then has the result that the track rests on the soil layer.
  • the gravel layer can also be removed by means of or one of the intermediate cars between the track removal wagon and the track laying wagon.
  • This expansion of the ballast can be done independently of the expansion of the soil layers, but also together.
  • the development according to claim 6 proposes that the new gravel and / or the new soil materials are installed by means of the second work vehicle, ie with the track installation wagon.
  • the corresponding built-in machines are then seen in the direction of the machine in front of the machine to reinstall the track.
  • the development according to claim 8 proposes that behind the excavating device for the soil layers there is a processing device for the excavation bottom located under the soil layers.
  • This processing device is a working unit in the form of a milling cutter and / or an installation unit for improving the substrate.
  • the existing substrate can be worked up. This means that the upcoming soils are milled out below the excavation by means of the router.
  • the milling out soil improvers such as lime or cement or other substances or mixtures can be introduced.
  • Also can be leveled and compacted by means of the milling unit of the ground. This is done by means of appropriate technical modules available on the market or special constructions of the corresponding milling / installation unit.
  • the leading ballast cleaning machine can be introduced or applied or installed in the upcoming floor or on the upcoming floor.
  • soil improvers such as lime or cement can be added / mixed and introduced / installed.
  • the first embodiment of the work train in Fig. 1a has a seen in the direction of travel (corresponding to the arrow) first work car 1 and at the end of a second work car 2. Between this first work cart 1 and the second work cart 2 is a third work cart 3.
  • the first work car 1 is used to remove the track 4 consisting of rails 5 and sleepers 6.
  • the second work car 2 is the reverse process, namely the replacement of the track 4.
  • the second work car 2 still installation means 7 for the soil materials and for the gravel.
  • the third work cart 3 has an excavating device 8.
  • both the second work cart 2 and the third work cart 3 each have a crawler undercarriage 9.
  • step 1 in Fig. 1b the initial situation is shown.
  • Step 2 shows that the first work cart 1, the short yoke 12 and the long yokes 13 expands.
  • the crawler undercarriage 9 has moved down and is supported on the bottom layer 10 from.
  • step 3 it can be seen that by means of a gantry crane 14, the short yoke 12 and the long yokes 13 are moved to the second work cart 2.
  • step 4 it is shown how the excavating device 7 of the third carriage 3 expands the bottom layer 10.
  • the corresponding expansion material is removed.
  • this excavating device 8 not only the bottom layer 10 but also the ballast layer 11 expands simultaneously.
  • step 5 two things are recognizable.
  • the installation devices 7 build a new bottom layer 10 and a new ballast layer 11.
  • the long yokes 13 are installed on the new substructure thus formed.
  • the crawler undercarriage 9 of the middle, third work car 3 first moves on the old ground layer 10 (step 4) and then on the excavation floor (step 5).
  • step 6 is shown when at the end of the railway line to be rehabilitated encounters the existing railway line. This means that the trolleys of the first work vehicle 1 and the third work trolley 3 can be moved again on the track 4, so that the crawler chassis 9 is raised.
  • Step 7 shows how the last elongated yoke 13 is installed and then in step 8 the short yoke 12 is installed. The finished railway line is then shown in step 9.
  • Fig. 2a and 2 B shows that the installation means 7 are not arranged here on the second work car 2, but on the third work car third
  • the installation devices 7 are seen in the direction of travel (according to the arrow) behind the excavating device 8.
  • the third embodiment of Fig. 3a and 3b is based on the first embodiment of Fig. 1a and 1b , The difference is that the middle, third work car 3 still has a processing device 15 in the form of a milling and installation device for underground improvement for processing the substructure.
  • the plow can be used to milled the pending soil underneath the excavated layers.
  • soil improvers such as lime or cement or other substances or mixtures can be introduced with the milling.
  • the soil can then be leveled and compacted. It is also possible that by means of this processing device fines of the screened ballast of the leading ballast cleaning machine introduced into the pending floor or on the upcoming floor or applied / installed.
  • soil improvers of the type described above can also be supplied / mixed and introduced / installed.
  • the corresponding processing with this processing device 15 takes place in steps 4 to 6.
  • the number of work cars and the arrangement of the work equipment are shown purely by way of example.
  • the first work car 1 and the second work car 3 not only a single intermediate work car, but several intermediate work car be arranged, which are equipped with appropriate machinery.
  • the arrangement and number of crawler tracks is equally variable here.
