Definitions

  • the present invention relates to a method for renewing a Track system with a substructure, a bedding, in particular made of gravel, and a track made of rails and sleepers.
  • Track systems have to be renewed from time to time because of the ballast bedding is changed by the load.
  • the Crushed stones crushed by the load This can cause a deviation occur from the intended track position, without costly conservation measures can lead to a hazard.
  • the invention has for its object a method for renewal to specify a track system, through which an advantageously renewing track system by a modern track system with great stability can be replaced.
  • the solid roadways produced by the method according to the invention have the advantage of particularly high strength and positional accuracy. Such lanes can therefore be used in particular for high speeds be used.
  • the renovation can be carried out in a favorable manner become.
  • renewal can be achieved through track-bound work also for track systems that are not accessible from the side. Delivery and removal of the materials can also be advantageous done over track.
  • the base layers are installed also track-bound. This step can also be done be carried out advantageously.
  • the installation is carried out of the new substructure a dismantling of the existing tracks and a Laying of rails, so that then the installation of the base layers can be done using the training rails.
  • Rails can also be installed after the track has been dismantled the solid road with high accuracy.
  • a further embodiment of the invention takes place after installation of the new substructure a dismantling of the existing tracks and the installation the base layers using a floor undercarriage, in particular of caterpillars. This eliminates the need to lay Auxiliary rails.
  • the set-up takes place and fixing the new track on the asphalt or concrete base course already when building the new track.
  • the. altitude the asphalt or concrete base layer at the designated support points the thresholds and the thicknesses of the thresholds in the range of Support points for the rails measured, from the measured values determines the need for height compensation and its size and suitable compensation means attached when laying the track section.
  • the height of the Rail measured at the bearing points on the sleepers and during the determination height compensation is also taken into account.
  • this measure can also compensate for the height tolerances of the rails and thus the deviations of the altitude of the laid track from the Setpoint can be further reduced.
  • the measurement of the Height of the base course and / or the rail height when laying the Track section, especially immediately before placing a Threshold, taking the compensating means before inserting the rail into the Sleepers are attached. This simplifies and improves the determination the bearing point to be measured on the base layer and it section of rail to be measured. By attaching the compensating means before inserting the rail into the sleepers, there will be a loosening the rails from the sleepers to attach the compensating means dispensable.
  • the threshold is reduced fixed against shifting. This ensures that the rail remains on the measured section of the base layer and the accuracy achieved by applying the compensating means the altitude remains unchanged.
  • the height ratio is preferred when determining the height compensation between the left and right rails of a threshold, the altitude ratio successive thresholds and / or the longitudinal height ratio between two at a given distance, for example five meters of mutually arranged measuring points are taken into account. This can take into account all the usual requirements for positional accuracy be worn.
  • the position of the track section in the transverse direction preferably starting from the middle of the sleeper, aligned before fixing. This is advantageously not only the altitude but also the longitudinal direction of the track section and the tolerances are reduced.
  • the height and lateral position of the track section can be determined according to an embodiment of the invention by means of applied to the base layer Auxiliary points are made. Likewise, the determination can also be made about Lasers are made from fixed points. Have these methods of determination turned out to be particularly suitable.
  • the measured Values, the compensatory measures taken and the final Track position documented. This means that the starting position can be called up at any time was given and with which measures which final result was achieved has been.
  • A is preferably used to carry out the method according to the invention
  • a trough is completely dispensed with. Instead the track section is supported directly on the lower base layer. After aligning the lateral position of the track section, this is done using fixing elements fixed, which is introduced into the lower base layer and attached to each to be attached to a threshold. In particular, bolts are used for this used.
  • the track section is aligned in the case of the invention Procedure by a separate device.
  • the support the threshold can, for example, as in the conventional method via spindles that are screwed into appropriate sleeves that are provided in the sleepers by the manufacturer. Because of the absence of the trough and the direct support on the lower one Appropriate spindles and sleeves are required. It can be used to equip all known or new types of sleepers become.
  • An advantage of the method according to the invention is that no Trough more is needed. This eliminates the need for producing the trough effort required. It is also particularly advantageous that the Gap between the cast upper base layer and the trough is eliminated, which due to their continuous extension upon ingress of water poses a particular danger.
  • the bolts in recesses previously made in the lower base layer can be positioned very precisely with which there is also an exact positioning of the bolts results.
  • the necessary displacements of the sleepers relative to the bolts when aligning are relatively small.
  • the thresholds in the height slidably attached to the bolt This has the advantage that the sleepers after loosening their support on the lower base layer can follow a shrinkage of the top base material.
  • the thresholds after supporting the sleepers on the lower base layer of the Rails released. This prevents shifts, in particular Thermal expansion and contraction of the rails during the Setting of the upper base layer are transferred to the sleepers.
  • the bolt in the Attached to the middle of the threshold is halved.
  • the invention is under the thresholds one covering several thresholds and in particular with these connected reinforcement provided, which in the upper base layer with is poured.
  • the reinforcement is connected to the threshold reinforcement.
  • the recesses in the lower base layer introduced as holes. These can advantageously be introduced with particularly high accuracy.
  • Another Possibility is the recess as in the longitudinal direction of the road continuously insert slot.
  • the alignment takes place the side and / or height of the track section in two or more Steps. This has proven to be particularly advantageous.
  • the formwork elements via an upper formwork holder on the rail foot and one lower formwork holder anchored to the reinforcement.
  • the bottom one Formwork holder preferably cast in. This can be done with simple A formwork for pouring the upper base layer is attached become.
  • the formwork can extend to the lower formwork holder be reused. Basically, it is also possible to get one Formwork trolleys of a conventional type to be used.
  • thresholds can be one-piece Sleepers with a vertical slot in the middle of the sleepers or Recordings attached to the side of the sleepers for passage of the bolt can be used for the lateral fixation of the threshold.
  • suitable adjusting and fixing means in the slot or the receptacle through which the bolt can be passed and after aligning the track section against side shift relative is fixable to the threshold or vice versa.
  • the use of two-part sleepers has the advantage that the length of the joints between the threshold and the cast upper base layer and the weight of the threshold is reduced is.
  • the sheet is preferably formed in two parts, with two, one each Half of the passage opening parts. Can over the sheet the threshold in a simple manner on the bolt against lateral displacement be fixed.
  • the two-part design has the advantage that the bolt introduced before the threshold is fully aligned laterally can be made by separating the two parts sufficiently far pushed and assembled only after inserting the bolt.
