Definitions

  • the present invention relates to a method for improving or repairing track systems with a substructure and a ballast bed as a superstructure comprising the steps of: removing the ballast of the ballast bed, removing the material of the substructure to a desired depth, if necessary producing a new Erdplanums, installation of a new Substructure, producing a new ballast bed, in particular using recycled old ballast.
  • the present invention relates to a device for improving or repairing track systems with a substructure and a ballast bed as a superstructure with a first excavating device, in particular Aushubkette, for removing the ballast, a second excavating device, in particular Aushubkette, for removing substructure material, if necessary, a device for producing a new earth, a device for installing a new substructure and a device for producing a new ballast, in particular using recycled old ballast.
  • a first excavating device in particular Aushubkette
  • Aushubkette for removing substructure material
  • the invention has for its object to provide a method and an apparatus of the type mentioned, which are improved in contrast.
  • the object is achieved in that the first excavating device is designed for jointly removing the old ballast and material from a mixing zone in a transition region between old ballast bed and old substructure and that means for separating old ballast from the building material, a Device for mixing removal material remaining after separation of ballast, in particular sand, gravel, gravel and undersize, with material obtained during the treatment of old ballast (4 ') and / or with externally supplied material, in particular new material, and means for installing the build-up material mixed with conditioning material and / or external material are provided as or part of a new, mechanically improved undercoat and / or formation protection layer and / or antifreeze layer and possibly a new additional intermediate layer between new, mechanically improved undercoat layer and subgrade layer and / or frost protection layer.
  • the basic idea of the invention is to expand the mixed zone material together with the old ballast and to provide a separating device by means of which old ballast can be separated from the removed material.
  • the device may consist of two or more separation stages, wherein a first separation stage for separating coarse impurities, root system and clay chunks is formed, while a second separation stage is designed for separating old ballast.
  • ballast (4 ') accumulating material and / or externally supplied material especially virgin material, mixed and as a new, mechanically improved Substructure layer and / or layer protection layer and / or antifreeze layer and possibly a new additional intermediate layer between new, mechanically improved subgrade and level and / or frost protection layer installed again.
  • old ballast (4 ') accumulating material and / or externally supplied material especially virgin material, mixed and as a new, mechanically improved Substructure layer and / or layer protection layer and / or antifreeze layer and possibly a new additional intermediate layer between new, mechanically improved subgrade and level and / or frost protection layer installed again.
  • ballast As material for mixing with residual material to be rebuilt after separation of old ballast, consideration is given to treatment residues of old ballast recycled to recycling ballast, such as chippings from the sharpening of separated old ballast in an impact mill, superimposed and undersize from a grain sieve for separated old ballast and sieve residues from a finger sieve, branched off, not rebuilt as ballast bed, preferably at least partially processed and / or comminuted in a cone crusher and externally supplied material, especially new material in liquid and / or solid form including crushed new ballast.
  • the new subbing layer produced therefrom may be a mechanically improved layer under a topping protection layer or an antifreeze layer, or it may itself be a tarmac or antifreeze layer, or a part thereof in each case.
  • the old ballast For the preparation of the old ballast, this is preferably sieved in a finger sieve and / or fed to an impact mill for sharpening. Furthermore, the old ballast can be sieved in a grain sieve to segregate oversize and undersize and to produce ballast grains of the required sizes. Furthermore, the old ballast can be washed to remove impurities. As mentioned, precipitates from said facilities can be admixed with the remaining material or a part thereof after separation of old ballast, before this as a new, mechanically improved base coat and / or layer protection layer and / or antifreeze layer and possibly a new additional intermediate layer between new, mechanically improved undercoat layer and subgrade and / or antifreeze layer or part thereof is incorporated.
  • a roller grate can be used to separate Grob especially, such as large stones and tufts of grass.
  • a magnetic separator may be provided to separate metal parts.
  • the branching point (by-pass) for old ballast not to be rebuilt as recycling ballast can be arranged after this separation stage and / or before or after the washing screen for the old ballast.
  • the excavation depth and width are preferably adjustable. As far as material is not reusable or is to be reused, this is removed as spoil.
  • expanded mixed zone material is mixed prior to replacement as a new base coat with accumulating in the treatment of old ballast material and / or externally supplied material, in particular new material, is also claimed independently.
  • the same materials can be mixed as described above.
  • the layer protection layer and / or the antifreeze layer can also be installed in two or more layers.
  • this two-layer or multi-layer layer can also be installed at least temporarily instead of a new, mechanically improved substructure layer, especially if no treatment material for such a new, mechanically improved subgrade is available, such as at the start of construction or a construction interruption or if, due to the nature of the old track bed, no suitable material can be obtained for a new, mechanically improved subgrade, such as mud or a clay lens.
  • the advantage here is the installation of two or more layers in a single operation.
  • FIG. 1a the excavating part
  • FIG. 1b represents the built-in part including material supply from external.
  • the excavation of old ballast 4 takes place together with material from the mixing zone 6 via a first Aushubkette 1.
  • the excavated material is supplied to the separation stage 1, where coarse impurities such as root system and clay soil be removed and disposed of.
  • the disposal takes place as shown as overburden by means of so-called material conveyor wagons, MFS.
  • MFS material conveyor wagons
  • the material not supplied to the overburden of the separation stage 1 is then fed to a second separation stage 2, wherein between a magnetic separator may be provided to remove metal parts. These are also disposed of via MFS.
  • finer impurities such as sand, gravel, abrasion and undersize are removed. These materials are for the above described admixture for the newly installed underground layers according to line (1) or (2).
  • the material remaining after separation of the fines ie in particular ballast, is then fed to a finger screen as the third separation stage.
  • a finger screen As the third separation stage.
  • a bypass to a cone crusher may be provided in front of the finger screen to break a portion of the separated ballast and reuse it for a new subheading layer, as shown by line (2).
  • the old gravel separated by the finger sieve can then either be reused directly as recycling (RC) gravel or fed to an impact crusher, in which the gravel is sharpened. Residues of the impact crusher serve again as admixing material for the new substructure layer according to line (1) or (2).
  • ballast sharpened in the impact mill is then fed to a grit screen to obtain ballast of the desired grain size.
  • Over- and undersize grain from the grain sieve is again used via line (1) or (2) as Zumischmaterial for the new subheading.
  • the sieved gravel is fed to a washing sieve, wherein before or after the washing sieve a bypass to a cone crusher can be provided.
  • Separated and broken old ballast is in turn used via line (2) as Zumischmaterial for a new layer of underground.
  • the remaining cleaned ballast is reused as RC ballast.
  • the broken in the illustrated cone crushers old ballast can also, as shown, solid or liquid, in particular chemical additives are supplied to be used also as Zumischmaterial for the new underground coat.
  • the installation of a new substructure layer is exemplary in FIG. 1b shown.
  • the material obtained via line (1) or (2) can, as shown, be installed directly as a new, mechanically improved substructure layer 8 or 9, wherein a geotextile can first be laid on the substrate 7.
  • the admixing material of line (1) or (2) can also be supplied to a mixing device 13.
  • This mixing device 13 can also be supplied diverted recycled gravel, which is preferably broken by a cone crusher.
  • the mixer 13 can be supplied with new material, including new ballast, whereby this new ballot is preferably broken.
  • the mixed material in the mixer 13 can then be installed according to line (3) as a new, mechanically improved substructure layer 9 or as an additional intermediate layer 12 on a new, mechanically improved substructure layer 8, 9.
  • the material from the mixer 13 can be fed to a further mixer 14, in which material is mixed for a leveling and / or antifreeze layer.
  • the mixer 14 also new material can be supplied.
  • the mixed material in the mixer 14 is then installed according to line (4) as a level and / or frost protection layer 10. But it is also possible to mix only new material in the mixer 14 and according to line (5) install as a level and / or frost protection layer.
  • All layers 8, 9, 10 and 12 are preferably leveled and compacted by means of a leveling and compacting device.
  • a geotextile can be placed. The same applies to the new intermediate layer 12.
  • a new ballast bed 11 is produced, namely, as shown, by means of a device 15 made of recycled ballast and / or a device 16 made of new ballast.
