Definitions

  • the invention relates to a method for refurbishing the substructure material located under the track of a railway track.
  • the substructure materials are to be understood in the most general sense.
  • the substructure materials are gravel, soil material, earth masses, etc.
  • this substructure material is to be understood in the most general sense.
  • the substructure material is fractionated in the sense of the workup according to the invention, separated, purified, worked up, etc.
  • the substructure materials in railway lines are subject to wear over the years due to mechanical stress.
  • the original Neophyte undergoes changes in its grain size and in its grain composition by grinding and smashing changes.
  • This increases the fines content, in conjunction with a natural organic and chemical pollution.
  • the ballast mixture must be regularly subjected to a cleaning process.
  • the ballast is subjected to a mechanical fines cleaning at a achieved fine fraction of 20 to 30% in the rule. In concrete terms, this means that if the fine fraction of the grain (less than about 22 mm) is 20 to 30% of the total ballast fraction, a ballast cleaning is required.
  • the fine fraction of 20 to 30% is lost ballast, which is caused by the non-reusable ballast masses in the ballast cleaning. This loss gravel must be compensated by supplying Neuschotter.
  • ballast cleaning measures in which only the ballast is cleaned and replaced, the above fine fraction is always disposed of.
  • the fines are spent by means of rail cars or trucks to a disposal point or a refurbishment outside the track area. The fines must then be worked up or disposed of in a facility approved under the environmental guidelines.
  • MFS cars / MT cars on the market, which can bunker and transport materials on construction sites in the track construction sector.
  • the cars are then used to material on the track axis in one direction or in different To transport work directions without having to leave the track restriction profile (clearance gauge) with the material.
  • ballast cleaning machines There are still track-laying machines on the market that can pick up, clean and re-install the ballast to be excavated.
  • the material within the overall machine is removed on one and the same work cart, cleaned and the cleaned track ballast material fed back to the existing track body.
  • the waste material in the form of undersize and protection is transferred to so-called MFS cars for transport.
  • the fine fraction is transferred to the so-called MFS / MT cars for final recycling and disposal.
  • MFS / MT cars for final recycling and disposal.
  • this waste in and of itself, for use in other construction purposes, includes grain fractions in its resulting fine fraction mixture.
  • the fine fraction mixture obtained during the ballast cleaning process contains absolutely no longer usable fine components such as organic components (humus, abrasives, impurities, etc.), but also theoretically reusable materials such as rock fractions which are below the grain size according to DIN again to be installed ballast fraction.
  • the fine fraction with grain sizes smaller than about 22 mm is treated as waste.
  • a relevant method according to DE 101 28 374 A1 relates to the supply of a construction site with building materials in the form of various bulk materials that are required at the same time or successively at the site, in the embodiment according to the FIGS. 6 and 7 only the removed old crushed stone is fractionated, cleaned and reused, but the fine fraction is disposed of.
  • the object of the invention is to provide a method for working up the substructure material under the track of a railway line with greater effectiveness in the sense that more parts of the original substructure material can be reused after the workup.
  • a method for refurbishing the under-track subway material is created, which is characterized by a high degree of effectiveness in the sense of maximum reuse of the refurbished substructure material.
  • the inventive method is characterized by the use of a track-bound and above all modular work vehicle system. Under the module system is to understand that each work car defines an individual work-up module, without this work car has other tasks. In addition to the individual processing of the substructure material, the corresponding work car can of course also caching the material and / or further transport.
  • the basic idea of the method according to the invention for refurbishing the substructure material located under the track of a railway track is that a plurality of different refurbishment work trolleys are provided in succession, which separates the substructure material into different fractions in the context of the workup according to the invention. This means that with the processing work car set up in succession, the separated fraction size becomes larger and larger.
  • the modular assembly of individual machines is used without interruption of the track-bound work flow for processing and for further processing according to the invention of the fines obtained during ballast cleaning. This means a total of a simple and targeted workup, separation and purification of incurred in the ballast cleaning fines, which would otherwise be supplied to the disposal.
  • the above-described gravel shares are separated and processed one after the other.
  • the reworkable fines such as the natural aggregate below the fraction of 22 mm separated and cleaned and made available for other purposes, while the no longer usable fines such as soil, humus, dirt, etc. are finally disposed of. This eliminates the disposal or processing of fine fraction fraction smaller than, for example, 22 mm at a track independent disposal or refurbishment.
  • a refurbishment module is arranged at the end of the refurbishment work cart.
  • the refurbishment module of the invention is at the end of the respective work car.
  • the refurbishment module is disposed within the conveyor line.
  • the material is transported through conveyor belts in the roof area or abandoned by conveyor belts of the neighboring car.
  • the use according to the invention of a work-up module at the point of application of an MFS wagon / MT wagon enables additional fractionation and processing of the existing fines without interruption of the working flow with little technical effort.
  • the refurbishment module is arranged in the roof area of the refurbishment work cart.
  • the refurbishment module is part of a roof frame which is separate with respect to the actual refurbishment work trolley and which is arranged on the actual refurbishment work trolley, if necessary.
  • the basic idea here is that the entire roof rack can be removed with its processing module removable and replaced with another roof rack with another processing module of the work car.
  • this roof rack may alternatively be a roof rack without processing module, which has only standard conveyor belts.
  • the base work car can be used universally as such. It can thus be used as a normal work car for bunkering of materials and / or for the transport of materials, but also be used in the sense of the invention by replacing the roof rack such that a workup of the substructure material in the sense of the invention is possible.
  • a sieve is used for fractionating the substructure material.
  • the workup modules usually have a sieve and fractionation unit using a sieve grate to separate the desired grain.
  • the sieve grates can also be designed as roller grates.
  • the hole width of the mesh grates or the roller grate size is decisive for the fraction size.
  • the mesh grids can be changed to vary the hole size of the screening and thus the desired Siebkörnung.
  • both the bottom conveyor belts and the roof conveyor belts can have end-side transfer belts. This means that by means of conveyor belts of the work vehicle, a universal material transport from work car to work car is possible.
  • Fig. 1 shows a work train to rehabilitate a railway line.
  • This railway consists of a track 1, which rests on a substructure material 2.
  • This substructure material 2 consists essentially of gravel and underlying earth masses. Also, a layer protection layer is conceivable.
  • the work train initially has a track-bound expansion-work cart 3 for removal and installation of the base material 2, in particular of the ballast on.
  • the expansion work cart 3 is optionally followed by a transfer work cart 4.
  • the further provided intermediate bunker work cart 5 serve the intermediate bunking of materials.
  • the adjoining additional work cart 6 serves for the separation and washing of the substructure material 2 in the case of lack of space as an extension of the subsequent modular cleaning work cart 7.
  • the refurbishment work cars 8, 9 each have a refurbishment module 10 at one end, namely where the substructure material 2 to be processed is supplied.
  • These refurbishment modules 10 may, in the most general sense, be a sieve 11, as it appears in FIG Fig. 3a as a grate and in Fig. 3b is shown as a roller grate.
  • the removed substructure material 2 is given up to the refurbishment module 10 of the refurbishment work cart 8.
  • a first fractionation of the ballast is carried out via the screening device 11.
  • Fig. 2b It can be seen that the larger gravel parts do not pass through the sieve device 11. Only the finer gravel parts pass through the sieve device 11 and are picked up by the first refurbishment work cart 8.
  • the ballast fraction which has passed through the screening device 11 of the first work-up work car 8, passes via the roof conveyor belt 13 to the second work-up work car 9 and arrives at the work-up module 10 of this second work-up work car 9.
  • the screening device allows the corresponding fraction to pass, while the ballast material, which is not allowed to pass through the screening device 11, is transported further and possibly fed to a further processing work cart.
  • the passage size of the screening device 11 of the second work-up work cart 9 is greater than the passage size of the screening device 11 of the first work-up work cart 8.
  • Fig. 5 It is shown how the screening device 11 may additionally be associated with a washing device 15.
  • This washer 15 cleans the ballast of unusable fines such as dirt, humus, organic soil and components, chemical contaminants, etc. These non-usable fines are eliminated through final disposal.
  • Fig. 6a to 6f show in different embodiments, the material flow of the supplied substructure material 2 to the refurbishment module 10 of the respective work-up work car 8, 9.
  • the black arrows show the gravel with larger fraction size and the white arrows show the gravel fraction with smaller grain size.
  • the ballast fraction with the smaller grain size falls through the screening device 11.
  • the ballast is fed via different ways, namely via roof conveyor belts 13 and transfer conveyor belts 14 to the refurbishment module 10.
