  • the invention relates to a device, in particular a wagon, for aligning a track support slab with respect to a subsoil with a chassis and a running gear for moving the chassis along the track support slab.
  • the invention relates to a method for aligning a track support slab with respect to a subsoil and a method for producing a solid track.
  • slab tracks are used in railway construction and typically have a solid rail superstructure, which usually consists of concrete or asphalt, instead of ballast or other loose materials.
  • Slab track is used, for example, on high-speed routes or in tunnels and is characterized by increased stability and durability compared to ballasted tracks.
  • slab tracks often consist of prefabricated concrete track supporting slabs, which are typically prefabricated in a factory and then joined together on site and connected to the rails. Then the track support slabs together with the rails are precisely aligned according to the specified route. For this purpose, the laid track support slabs are measured using a measuring device and then aligned with the subsoil. This requires a team of several specialized people who work simultaneously on measuring and aligning a track support plate. Sometimes the position of a track slab needs to be remeasured or corrected. The production of slab tracks is correspondingly time-consuming and expensive. In any case, when aligning track supporting plates, a high degree of precision is required so that trains can later travel the route at high speeds without any safety risk.
  • Solid tracks and methods and devices for the production and alignment of solid tracks are, for example, from the prior art EP 2 503 059 A2 , the EP 1 039 033 A1 or the EP 1 533 420 A2 known.

Since the spacer elements 14 can be easily offset, it is favorable if the actuating units 19 can be positioned, preferably electrically, relative to the chassis 3 . The adjusting units can preferably be moved in a plane parallel to the main plane of extent of the chassis 3 .
  • the adjustment device 18 can have at least one gripping element 23 with which the track support slab 2 or a rail 5 on the track support slab 2 can be gripped. After a track support plate 2 has been aligned at an alignment position 21, the gripping element 23 can be released again.
  • two gripping elements 23 are provided, one of which is arranged on two opposite sides of the chassis 3 .
  • track support slabs 2 are first joined together and placed on a concrete block or concrete base 25, in particular with a steel plate (not shown), or a similar base.
  • a steel grid not shown, can later be used to reinforce the concrete that is yet to be poured.
  • counter elements 26 for the spacer elements 14 are placed on the substructure 10 below the track support plates 2 .
  • the counter-elements 26 are designed to at least partially accommodate spindles 15 and have an internal thread (not shown). The counter elements 26 improve the support of the spacer elements 14 against the ground 10. After the placement of the track support slabs 2 on the concrete blocks 25, these are like described aligned with the device 1.
  • the spindles 15 can be supported on the concrete bases 25.
  • a new alignment, a follow-up check as to whether the actual position P actual of the track support slab 2 actually corresponds to the desired position P desired , or a control run with the device 1 can be carried out. During the control run, it can also be checked whether the actual position Pactually corresponds to the target position Psoll.
  • a measurement protocol can also be created and transmitted automatically, preferably in real time, to a project storage platform. This allows the status of the work and the quality to be checked, preferably in real time.
  • the area 27 below the aligned track support slabs 2 can then be filled with concrete (not shown). After the concrete has hardened, the slab track 24 is produced.
