Abstract
For the purpose of rehabilitation, a ballast bed of a track is taken up in the form of an upper bed layer by a first clearing device and cleaned. The bulk material accruing in the process is discharged in front of the first clearing device—with regard to the working direction—laterally upon the ballast bed in a bed region. The latter can only be covered by the second clearing device which is configured to be of greater width—with regard to a transverse direction of the track—than the first clearing device. Thus, it is possible to intermediately store bulk material, accruing in a front end region of a machine, on the ballast bed for later use.
Claims2
A method for rehabilitation of a ballast bed of a track, which comprises the steps of:
- taking up an upper bed layer via a first clearing device—with regard to a working direction—with an endless clearing chain guided around the track;
- taking up a lower bed layer adjoining the upper bed layer via a following, second clearing device with a further endless clearing chain guided around the track;
- and
- discharging a bulk material in front of the first clearing device—with regard to the working direction—laterally upon the ballast bed in a bed region which is covered only by the second clearing device, the second clearing device having a greater width than the first clearing device with regard to a transverse direction of the track, so that the bulk material discharged is taken up together with the lower bed layer by the second clearing device.
