Definitions

  • the invention relates to a method and a device for processing and Checking used concrete sleepers of a superstructure of railways.
  • Components of a superstructure of railways are rails and sleepers, connected by means of iron to track grates, switches and crossings are.
  • Small bars in this case include in particular sleeper screws, spring washers, Clamp plates and ribbed plates.
  • these ironmonger be Rails and sleepers bolted to a track grid.
  • Attenuation of Vibrations and to increase driving comfort is an intermediate layer Plastic or wood inserted between rail and the support surface.
  • the superstructure itself lies in a ballast bed, which in turn on a substructure rests. All the forces that are put into the rail will be through the sleepers over the ballast bed and transferred to the substructure.
  • the test and work-up according to the invention makes it possible in its sum, to get an idea about the condition of the concrete sleeper, which is in unexpected Way clearly beyond the mere sum of their individual parts and the previous ones State of the art goes out.
  • quality requirements which are placed on components of the superstructure, in particular concrete sleepers, disproportionately with the speed range for which it is used should be.
  • the test according to the invention and reprocessing allows in particular by a review the material properties of the concrete, the concrete sleeper in such a state Restore that use even without any speed limit is possible.
  • Claims 2 to 4 include advantageous embodiments of the invention Solution of claim 1.
  • the concrete threshold through the structure-borne sound analysis an ultrasound examination for possible presence of material damage of the concrete. This happens especially in the rail support area as well as in the area of the iron and the ribbed plate. Kicking unexpected Reflections of the ultrasonic waves introduced into the concrete are irregularities present in the concrete, in particular material damage and / or Transverse cracks. In these cases, the concrete sleeper is scrapped.
  • a Swinging test performed on the concrete sleeper by the concrete sleeper excited with at least one frequency to a vibration and the Reverberation time of this vibration is determined.
  • the concrete threshold becomes by a mass impact or a vibration exciter, in particular a Shaker, in the short term excited to swing. From a determined decay behavior, the so-called reverberation time, the vibrations and the determined natural frequencies
  • the concrete sleeper can be directly inferred on possibly in the concrete threshold pull existing longitudinal cracks. Be deviations from one expected Abklin and expected natural frequencies, the concrete sleeper is taken out of service.
  • a mechanical Impedance of the concrete threshold determined.
  • the concrete threshold with at least a frequency excited to a vibration, a force of excitation and determines an oscillation speed of the concrete sleeper. The relationship from the force of the excitation and the vibration speed results in the mechanical Impedance of the concrete sleeper. Be deviations from an expected Determined course of the mechanical impedance of the concrete threshold, the Concrete threshold retired.
  • the elasticity of the concrete sleeper is determined by a bending test.
  • the concrete sleeper is supported especially at their ends and applied on its upper side in the region of its center with a bending force.
  • the deflection of the concrete sleeper caused by the bending force is measured and compared with a predetermined limit. If the measured deflection exceeds the limit value, the concrete threshold will be exceeded retired.
  • the sleeper screws are used in particular with a screwdriver removed and possibly dowels turned off.
  • a lowering of the rail support area is measured and with the one brand new concrete sleeper compared. This must be the same measured value as in the brand new concrete threshold.
  • the iron is changed with a screwdriver and possibly dowels turn on again.
  • the sleeper screws are put on, tightened and clamped with a factory-new concrete threshold corresponding torque.
  • a visual inspection of the concrete sleeper 1 of FIG. 1 is carried out first, paying particular attention to outbreaks, visible cracks, sharp edges of the concrete sleepers body, in particular the underside, contamination by adhering pollutants, damage in Schienenetzlager Surrey Symposium and the state of the iron becomes.
  • the concrete sleeper 1 is in particular with a high-pressure water system cleaned.
  • smaller deposits will be involved solved at the concrete threshold, the concrete threshold 1 of dirt freed and detached loose concrete parts.
  • a swing - out test on the Concrete sleeper 1 performed by the concrete sleeper 1 with at least one Frequency excited to a vibration and the reverberation time of this vibration is determined.
  • the concrete sleeper 1 by a mass impact or a vibration generator, in particular a shaker, in the short term too Swinging excited.
  • the so-called reverberation time, the vibrations as well as the determined natural frequencies of the concrete sleeper 1 can be direct conclusions on possibly in the concrete sleeper 1 existing Pull longitudinal cracks. Be deviations from an expected Abklin as well as expected natural frequencies is determined, the concrete threshold 1 retired.
  • a mechanical impedance of the Concrete threshold 1 determined.
  • the concrete sleeper 1 with at least one Frequency excited to a vibration, a force of stimulation and a Swing speed of concrete sleeper 1 determined.
  • the relationship from the Power of the excitation and the vibration velocity results in the mechanical Impedance of Concrete Threshold 1. Be deviations from an expected Determined course of the mechanical impedance of the concrete sleeper 1, the Concrete threshold retired.
  • the concrete sleeper 1 is set in particular in the region of their ends on support 7 and acted on its upper side in the region of its center with a bending force 8.
  • the caused by the bending force 8 bending line 10 with the deflection 9 of the concrete sleeper 1 is measured and compared with a predetermined limit. If the deflection 9 exceeds the limit value, the concrete sleeper 1 is scrapped.
  • the sleeper screws 2 are in particular with a screwdriver removed and possibly all dowels 3 unscrewed.
  • a depth 12 of the rail support portion 11, as shown in Fig. 3 measured and compared with the corresponding depth of a brand new concrete sleeper.
  • the same measured value must result as with a brand new concrete sleeper. If the measurement shows that the rail support area 11 is lowered or unduly deformed due to the previous loads on the concrete sleeper 1 by rail traffic, the concrete sleeper 1 is taken out of service.
  • the quality of the anchoring of the sleeper screw 2 or of the anchor 3 in the concrete sleeper 1 is checked with a pull-out test of the previously tensioned sleeper screw 2.
  • the concrete sleeper 1 is secured in particular at the areas 5 against lifting.
  • a clamp 4 engages around the head of the sleeper screw 2 and pulls it with a certain pull-out force 6 opposite to its screwing.
  • the sleeper screw 2 must be firmly anchored in the dowel 3 and the dowel 3 with the concrete body of the concrete sleeper 1.
  • the concrete sleeper 1 is used for verification and documentation the quality checked.
  • a test seal and a permanent barcode attached are attached on the concrete sleeper 1 in particular.
