Definitions

  • the invention relates to a ballast bed renewal method according to the preamble of claim 1.

  • German patent application entitled "Method for supplying a line construction site with building materials and associated transport or conveyor chain, and this applicable classifying and fractionating" official file number 101 19 777.2, the priority of which is claimed by the present application the notifying party has proposed to deliver at a line construction site, such as track construction site, required materials (for example PSS / FSS material and ballast) in a premixed condition and then classify them according to at least one bulk material property, possibly grain sizes or grain size ranges, in relation to the construction site and - according to the classification - to fractionate in order to provide the classification corresponding bulk fractions in association with the site.
  • required materials for example PSS / FSS material and ballast
  • at least one bulk material property possibly grain sizes or grain size ranges
  • gravel / sand material and ballast are delivered in non-sorted, possibly more or less mixed state and then separated by sieving.
  • the object of the invention is to treat old ballast as part of a ballast bed renewal process so that the ballast bed can be reconstructed as much as possible based on the recycled old ballast, the processed ballast should have essentially Neuschotterteil.
  • the old ballast is subjected to at least one fractionation treatment, by which at least one ballast fraction of a grain size range of smaller grain sizes and at least one ballast fraction of a grain size range of larger grain sizes is obtained from the old ballast, optionally with separation at least a residue fraction, and that then the gravel fraction of the grain size range of larger grain sizes is subjected to at least one crusher treatment, optionally with separation of a residue fraction, and then the crushed fraction subjected to the crushing fraction of the grain size range of larger grain sizes and the no-crushing crushed fraction of the grain size range of small grain sizes at least one Gravel fraction of a particle size range smaller and larger grain sizes is merged.
  • at least one fractionation treatment by which at least one ballast fraction of a grain size range of smaller grain sizes and at least one ballast fraction of a grain size range of larger grain sizes is obtained from the old ballast, optionally with separation at least a residue fraction, and that then the gravel fraction of the grain size range of larger grain sizes is subjected to at least one crusher treatment,
  • the ballast fraction generally bulk fraction
  • the smaller grain size is not destroyed by the breaker treatment, but is retained and can be fed back to the fraction broken down. In this respect, no losses occur on the ballast or bulk material fraction of the particle size range of smaller particle sizes.
  • the breaker device due to the non-feeding of the ballast or bulk material fraction of the particle size range of smaller particle sizes, the breaker device can be better tuned or adjusted to the crushed or crushed material fraction of the particle size range of larger particle sizes, resulting in better crushing results on the one hand and less wear on the other hand the breaker device result.
  • the resulting bulk fraction (possibly ballast fraction) of the particle size range of smaller and larger particle sizes will undergo at least one separation treatment to separate at least one residue fraction in order to further improve the quality of the recycled bulk material to improve.
  • the chipped or dissolved during the breaking process parts are thereby separated and, for example, other residues supplied for disposal.
  • the aggregated ballast fraction of the grain size range of smaller and larger grain sizes may be advantageously subjected to a clay precipitation treatment. It also does not seem completely out of the question to subject the old ballast to a clay precipitation treatment before the fractionation treatment. However, it is particularly preferred to subject only the ballast fraction of the grain size range of larger particle sizes of the clay precipitation treatment, preferably before the crusher treatment, so that the crusher is not burdened with the clay.
  • the merged ballast fraction in the course of the washing treatment first passes a first washing arrangement in which the merged ballast fraction is exposed under centrifugal force wash water or / and a high pressure Bebrausung is exposed to wash water and then passes a second washing arrangement in which the merged ballast fraction on a washing screen is exposed to high pressure wash water jets.
  • the ballast fraction in the first washing arrangement can fall through a spray zone in which a plurality of, preferably rotating, high-pressure water jets act on the ballast fraction.
  • a particularly intensive Bebrausung the ballast fraction can be done with water, for example, with operating pressures of about 40 to about 80 bar can be worked.

  • the washing screen is moved for conveying and turning the ballast grains and that high-pressure washing water jets are directed from both above and below onto the ballast fraction located on the sieve.
  • the here indicated two-stage washing treatment of the ballast fraction is particularly advantageous in that the first washing arrangement allows effective pre-cleaning, so that the total water consumption is reduced. If the ballast fraction is less heavily polluted, then it can be passed over a bypass at the first washing arrangement. Furthermore, it should not be ruled out that in some situations treatment of the ballast fraction is completely sufficient only with the first washing arrangement. It is therefore generally proposed that the ballast fraction passes through the first or / and the second washing arrangement during the washing treatment.
  • the crusher treatment is used in particular to make the gravel again sharp-edged or pointed.
  • the ballast can be subjected to the clay precipitation treatment, if necessary or as required.
  • the ballast preferably passes through at least one spiked roller in order to separate mud bulges from the ballast.
  • the old ballast can be moistened before or / and during lifting by spraying with water. It can therefore be sprayed onto the old ballast before recording the old ballast from the track water or sprayed during recording, for example in a Aushubkette, water on the gravel to avoid the dust-generation or at least reduce.
  • a moistening of the ballast was previously contrary that a ballast dampening inevitably leads to the ballast contaminating foreign components (for example, soil material, such as clay) relatively firmly attached to the gravel and can not be removed from the gravel by a conventional process management again.
  • the washing treatment of the ballast provided according to the invention can reliably remove such adhering components, so that to a certain extent only the washing treatment according to the invention makes it possible to humidify the ballast for dust prevention.
  • a significant advantage namely a significantly reduced or even largely avoided dust development in the ballast cleaning, etc., which visual impairments and pressures on the environment and health of the staff are avoided or greatly reduced, especially in the case of extending in a tunnel track sections.
  • the clay excretion treatment and / or the spraying of the old ballast with water are carried out only as needed in the context of an overall process providing these steps.
  • the method according to the invention may be carried out as part of a tarmac improvement process in which the ballast bed and substructure of a track are dug and where the substructure is rebuilt using sub-grade material and the ballast bed using new ballast and / or reclaimed used ballast.
  • ballast bed can be rebuilt using new ballast and / or reclaimed old ballast while maintaining the existing track foundation.
  • a clay precipitation treatment for the crushed fraction of the grain size range of smaller grain sizes will generally not be required, as the clay tends to form quite large loams of clay or globules as a result of the fractionation treatment contained in the fraction of larger grain sizes.
  • the method according to the invention serves on a construction site proceeding along a line (hereinafter referred to as line construction site) and that the old ballast and the ballast fractions are transported along the line.
  • the line construction site may be a track construction site.
  • the method may then be carried out using a railroad tracker train having means for performing the method steps.
