Definitions

  • the invention relates to a method for cleaning a ballast bed of a track by means of track-bound machines, with a cleaning machine being used to remove ballast located under a track grid with a ballast removal device, with cleaned and/or new ballast being removed in several layers in relation to a working direction behind it a ballast installation device and a ballast train is introduced into the track and the introduced ballast is compacted by means of a tamping machine and a stabilization machine.
  • Ballast tracks have properties that ensure a safe and efficient
  • ballast must have sufficient stability and elasticity through a suitable grain distribution and good interlocking of the individual ballast grains. A low proportion of fine grain and high sharpness are decisive for this requirement.
  • ballast Over longer periods of time, dynamic operating loads and weather influences mean that the ballast increasingly loses its positive properties.
  • the ballast In order to restore an intact ballast bed, the ballast must be cleaned, supplemented or completely replaced.
  • a machine for cleaning ballast is known, for example, from AT 520989 A1.
  • a ballast removal device designed as an endless clearing chain, the ballast located below the raised track panel is continuously removed and fed to a cleaning system. Immediately behind this, cleaned and/or new ballast is applied to the existing subgrade using a ballast laying device.

  • MDZ mechanized maintenance train
  • DVS dynamic track stabilizer
  • ballast train consisting of ballast self-unloading wagons.
  • the track panel is lifted by the mechanical maintenance train and the new ballast is compacted under the sleepers. This process of new ballast feeding, track elevation and compaction is repeated to achieve a ballast bed of the desired height.
  • the top picture shows the first work phase of excavating the ballast and placing the ballast while lifting the track grid.
  • the ballast is removed with a cleaning chain from under the raised track panel.
  • the clearing height is usually 300mm.
  • the removed old ballast is screened and sharpened.
  • This cleaned ballast is brought back onto the track with a ballast conveyor and distributed with a plow to a maximum initial height of 150mm.
  • This maximum initial height is specified by the regulations of various rail infrastructure operators, for example by the French SNCF. According to the regulations, the ballast is compacted immediately afterwards using a stabilization unit, whereby the ballast bed height drops to approx. 130mm.
  • a stabilization unit whereby the ballast bed height drops to approx. 130mm.
  • new ballast is brought in using a ballast train and distributed using a plough.
  • the track grid is then lifted by 80mm ; while tamping the raised sleepers.
  • a subsequent stabilization process leads to a settlement of the track grid.
  • the third phase of work is a repetition of the second phase of work, with a further raising of 80mm and a settlement of about 280mm.
  • the ballast in the track is usually sufficient to carry out a final tamping process in a fourth work phase. However, it may also be necessary to unload new ballast in front of the tamping machine.
  • the tamping machine lifts the track panel by 20mm to 25mm into a specified geometry.
  • the subsequent stabilization causes a lowering to the original ballast bed height of approx. 300mm.
  • the ballast bed is profiled and the ballast grains lying on the sleepers are swept away.
  • the object of the invention is to improve the method of the type mentioned above compared to the prior art in such a way that all work can be carried out in a shorter track possession.
  • the quality of the compacted ballast bed should correspond to the specifications of the railway infrastructure operator.
  • the new process has the advantage that more cleaned ballast can be reused than with the known process.
  • This ballast is introduced into the track via the ballast insertion device immediately after cleaning and does not have to be temporarily stored or replaced with new ballast.
  • Another advantage is the reduction in tamping, which protects the ballast.
  • one pass is also eliminated for the ballast plow and the track stabilizer. Due to this reduction in work processes, fewer personnel are required on the track. This reduces labor costs and contributes to the safety of the track construction site.

This ensures that the original ballast bed height is reached with the remaining lifting operations without impairing the compaction quality.
  • the track panel is lifted by at least 50mm, in particular by at least 70mm. This means that only a small amount of lifting is required for the subsequent second tamping process in order to create the specified track geometry.
  • the track panel is advantageously lifted in the second lifting process with a lift in a range between 15 mm and 25 mm, in particular in a range between 20 mm and 25 mm. This leaves enough leeway for creating the specified track geometry without loosening the ballast bed unnecessarily.
  • the method is further developed by an advantageous deep tamping process in which, after the first lifting process using the deep tamping unit, a first tamping process is carried out in a lower deep layer of the ballast bed with vibrating and tilting tamping tools and a second tamping process in an upper deep layer of the ballast bed with the same tamping tools .
  • the track panel is held in position during the tamping process using a lifting unit.
