Definitions

  • the invention relates to a method for rehabilitating railway lines for train traffic according to the preamble of claim 1.
  • railway lines basically consist of a track substructure and a track superstructure.
  • the track substructure consists of at least two layers, namely, for example, a gravel layer and a layer protection layer and / or frost protection layer. This track substructure must be renewed from time to time.
  • the track superstructure consists of the track, namely the sleepers and the rails / yokes. Also this track superstructure must be renewed from time to time.
  • ballast cleaning technology for the ballast is to pick up the existing ballast below the track and the ballast from the threshold compartment areas, to clean it inside the machine and then reinstall it.
  • gravel is introduced as Ver Schollschotter in the existing track. Dirt and dirt particles are separated and loaded on railway wagons and transported away.
  • the cleaned ballast in a further operation by means of washing water. This is done by irradiation or by vapor deposition of the ballast.
  • the washing water must be collected after completion of the washing process and properly clarified or disposed of.
  • the washing of the ballast takes place here in the wake for screening or refraction, but may also be integrated in the screening process.
  • the washing can also take place in a separate washing module within the machine or in series.
  • a novel washing system is used to clean the ballast.
  • blasting machines are used with nozzles, which uses CO 2 dry ice in the form of pellets.
  • the spraying or irradiation of the ballast with these pellets takes place either during the screening process or in a separate module in the wake.
  • the spraying or Irradiation of the ballast by means of CO 2 dry ice as in previous ballast washing systems in the wake for refraction and screening done.
  • the entire surface of the ballast with the CO 2 dry ice is applied, so that thereby the entire surface of the ballast is cleaned.
  • the ballast is preferably permanently rotated, for example in a vibrator during CO 2 dry ice.
  • the advantage of this special ballast cleaning is that the dissolved by the dry ice protection particles are dry and free of wash water.
  • the dirt particles can be introduced into the disposal masses of the dirt ball and the dirt particles and transported away with the soil masses to be disposed of via the normal conveying and transport technology. Separate collection and disposal is not necessary. There must be no containers for dirty washing water on the machine, as is necessary when cleaning with water. Thus, machine facilitation in the design and large savings in the clarification and disposal of accumulating wash water can be realized.
  • the advantage of using CO 2 dry ice is that it achieves effective and rapid cleaning of the ballast in a "dry" manner.
  • the development according to claim 2 proposes that the CO 2 dry ice is thrown in the form of pellets on the surface of the ballast. These pellets burst on the surface causing the contaminants to detach from the surface.
  • the inventive idea of the innovation is that the cleaning machine for the ballast not - as before - reintegrated the cleaned ballast itself, but that a modified transfer of the cleaned ballast is performed, namely to a built-in machine for ballast.
  • a modified transfer of the cleaned ballast is performed, namely to a built-in machine for ballast.
  • this cleaning machine can be used before another single machine and can work continuously with this single machine together.
  • This single machine may be a track renewal train or a tarmac improvement machine.
  • the cleaning machine carries out the ballast cleaning as a single machine.
  • ballast cleaning machine can not perform further work steps in a machine unit.
  • the innovation according to the invention thus consists overall in that the cleaned ballast is not completely reintroduced into the track below the cleaning machine, but rather that it transfers the ballast - at least partially - to another machine.
  • the conveyance of the ballast to the separate machine unit can be done via conveyor belts, in a variety of ways. This can be done below the machine, laterally or elsewhere in the machine.
  • the second machine can be arbitrarily ranked in the cleaning machine. As stated, this second machine can be, for example, a track renewal train or a tarmac improvement machine. As a result, all of the cleaned in the cleaning machine ballast can be partially or completely taken over and installed by existing on the market single machines.
  • the cleaned ballast is fed directly to that machine which requires the cleaned ballast for installation. But it is also possible according to the embodiment in claim 6 to temporarily store the ballast in one or more intervening cars.
  • FIG. 1 illustrated cleaning machine 1 is used for removal, cleaning and installation of ballast 2 a railway line.
  • This gravel 2 forms the track substructure.
  • this track substructure Above this track substructure is the track superstructure, namely the track 3.
  • the working direction of the cleaning machine 1 takes place in the drawing to the left.
  • the ballast is released via an expansion unit under the track 3 and taken on the side of the track 3 via a conveyor channel 4.
  • the ballast 2 is separated into a reusable fraction having a maximum and a minimum grain diameter.
  • the too large ballast stones as well as the too small ballast stones and finally the dirt particles are conveyed by conveyor belts 8 to - not shown - pallet truck, usually material handling silo cars and transported away.
  • the cleaned ballast 2 is transported below the cleaning machine 1. There, the cleaned gravel 2 can be installed.
  • the black arrows indicate the gravel / soil to be disposed, and the white arrows indicate the reusable gravel.
  • the cleaned ballast 2 is not reinstalled below the cleaning machine 1, but the ballast 2 is fed via the conveyor belts 9 of another machine 10.
  • this machine 10 may be a built-in machine for the ballast 2, namely a so-called tarmac improvement machine.
  • tarmac improvement machine As a further machine 10 and a track renewal train would be conceivable, which renews the track 3. If this track renewal train has no integrated planum improvement machine, then in any case an additional installation machine for the ballast 2 is provided.
  • Fig. 2 additionally shows the possibility (indicated by the white arrow pointing downwards) that the cleaning machine 1 installs a part of the cleaned ballast 2 at the same time and does not supply it entirely to the separate machine 10.
  • Fig. 3 shows that 7 are located above the nozzle 11 in the field of screen.
  • these nozzles 11 are CO 2 dry ice pellets with high pressure thrown on the gravel 2.
  • the pellets burst on the surface of the ballast 2. This dissolves the dirt. This falls through the sieve.
