Definitions

  • the object of the invention is to provide a method for crack repair on concrete sleepers of track systems, with time-consuming work such as the removal of the track, the track bed and the concrete sleeper can be avoided and a reliable complete crack filling is possible.
  • the leakage of the filling material from the crack is monitored in a fifth step. Based on the monitoring result, the low-pressure pump is controlled. This monitors the quality of backfilling and the reliability of the process.
  • claim 3 is used as filler one-component, two-component or multi-component epoxy resin or polyurethane. Depending on the initial conditions such as humidity, type of pre-contamination and degree of contamination as well as the damage pattern, the optimum fillers can be selected, put together and used. This improves the quality of the process and the subsequent remediation.
  • the respective cracks are rinsed by means of a solvent, the initial conditions in terms of moisture, the type of pre-pollution and the degree of contamination can be positively influenced and completely eliminated.
  • the filler to be used receives optimal réelle meetings and bonding options for concrete material of the concrete threshold.
  • the crack is blown out. This allows residues of the solvent used or others Remove residues. The quality of the restoration and the reliability of the backfilling are improved.
  • the injection device is used at the free surface by means of filler neck in the crack or placed on the crack by means of rubber lip.
  • optimal backfilling or injections of the filling material are achieved.
  • the quality of the process is improved.
  • the filling is carried out even with continuous or unsteady mechanical stress of the monolithic material.
  • the backfilling or rehabilitation of concrete sleepers are possible even in short traffic breaks between trains. Elaborate blockages can be avoided. As a result, a not to be underestimated cost advantage is achieved.
  • the concrete threshold in the region of the crack or the crack is mechanically expanded. This simplifies the filling process and makes it more reliable.
  • an individual sealing of the lower threshold region takes place with continuous cracking by means of a fast-potting material by a lateral introduction. This ensures that the cracks are closed in the lower part of the threshold and thus the subsequently introduced backfill can not escape down from the threshold.
  • the rehabilitation of cracks 1 on concrete sleepers 6 represents a high cost factor for the operators of track systems.
  • a crack remediation is possible, whereby the concrete sleeper 6 to be rehabilitated remains in the track system during the refurbishment.
  • the renovation takes place in successive steps after a detailed crack analysis.
  • the crack is first blown out and rinsed with a solvent which, for example, is hydrophobic.
  • the crack 1 or the cracks 1 are blown out again. After the cleaning process, the damming 2 of the crack 1 or the cracks 1.
  • the damming 2 takes place here based on the crack analysis.
  • the damming 2 is applied to the crack 1 so that it is completely covered.
  • the damming 2 is applied in strips along the crack 1 on the crack 1, wherein the damming 2 is made removable at intervals.
  • the crack is covered, for example, across the crack course and superimposed by the damming 2.
  • the filler 4 is injected into the crack 1 by means of a per se known injection device and a low-pressure pump.
  • a per se known injection device and a low-pressure pump.
  • packers ie filler neck 5, which are arranged in the crack 1, or by means of attachable or compressible on the crack 1 rubber lips 6.
  • an optimal Verhell310 is achieved.
  • the low-pressure pump is controlled so that the filling material 4 can penetrate into the crack 1 without bubbles.
  • the backfilling is monitored by monitoring the escape of the filling material 4 from the crack 1. Based on the monitoring result, the low-pressure pump is controlled.
  • the filling is carried out without interruption as a single operation, whereby, taking into account the pot life of the respective filling material 4, the filling process can be delayed.
  • filler 4 is both an epoxy resin and polyurethane in question.
  • a hydrophobic solvent such as acetone
  • filler 4 allows filling even with continuous or unsteady mechanical stress on the concrete sleeper 6.
  • a mechanical extension of the crack 1 or the area is provided directly at the crack.
  • special care is required to to avoid further damage to the concrete sleeper 6.
  • the filler neck 5 and the rubber lips 5 can be set so that an escape of the filler 4 will be avoided directly at the filling point.
  • a material with a rapid popping action is introduced laterally in this area by means of an injector.
  • This material is a jelly-like, fast-potting material, which is adjusted according to air humidity, dew point and building temperature. After curing of this material, the fourth step is carried out according to claim 1.
