Definitions

  • the present invention relates to a method for the long-term stabilization of the heavily loaded areas of railway tracks on a ballast bed, in particular in the area under the sleeper parts, which lie below and are connected to the rail track, and a device for carrying them out.
  • DE-B-23 27 063 describes a method for solidifying the ballast beds of railroad tracks, in which the binder is sprayed into the ballast structure when tamping and / or compacting in the effective range of the tamping and / or compacting tools.
  • An aqueous plastic dispersion or liquid bitumen is used. This method has not proven itself in practice.
  • DE-A-43 04 776 discloses a method and a device for the long-term stabilization of the tamping areas of railroad tracks. It is provided that the track grating, consisting of the rail and the sleepers connected to it, is raised 1 to 3 cm and the ballast bed below the sleeper is sprayed with an adhesive from the side of the sleeper head, whereupon in the usual way stuffed and leveled.
  • the object of the invention is therefore to develop a method for the long-term stabilization of the heavily loaded areas of railroad tracks on a ballast bed, in particular in the area under the sleeper parts which lie below and are connected to the rail track without the disadvantages mentioned above enter.
  • the ballast is preferably either temporarily removed up to the lower edge of the sleeper or mechanically pressed away by the spraying tool.
  • the easiest way to remove the ballast to the lower edge of the sleeper is by hand.
  • the removed ballast can then be refilled by hand up to the upper edge of the sleeper.
  • This embodiment of the method is particularly suitable for small track sections or more complicated track sections such as switches and crossings.
  • This method is carried out with the aid of a device consisting of
  • a device is preferably used which is characterized in that the outlet head is designed as a transverse tube with a plurality of boreholes arranged in rows.
  • the outlet head represents a triangle, which leads from the end of the static mixer to the ends of the transverse tube.
  • the transverse tube forms the base line of this triangle. It can be advantageous here to again design the two derivatives for the mixed two-component adhesive towards the ends of the transverse tube as a static mixer. This ensures that the two-component adhesive is mixed very reliably homogeneously.
  • An embodiment of the method according to the invention in which the ballast is mechanically pushed away, in the simplest case uses a sturdy, thick-walled tube which is closed and pointed at the lower end and has drilled holes on the sides.
  • the method is preferably carried out with an outlet head which is accommodated in a height-adjustable manner within a press-on protective chamber.
  • transverse pipe with a plurality of drill holes arranged in rows it can be accommodated in a protective chamber consisting of a smooth sheet which can be pressed into the ballast on the side of the threshold edge and a second sheet, preferably curved outwards, which can be pressed on mechanically, for example with the aid of a hydraulic pump.
  • these devices are driven into the ballast on the threshold side edge at least up to the lower edge of the threshold. Then the protective chamber is opened (pressed on hydraulically) and the spray head is lowered so that the spray jets are directed into the area of the ballast below the threshold.
  • Another embodiment of the device consists of a round spray head which has lateral bores. These holes can be selected so that areas up to 240 ° are covered, so that it is easily possible to reach the heavily used areas of train tracks.
  • Such spherical outlet heads are preferably accommodated in a tube which is adjustable in height and which bare tip. Pipes of this type can be driven into the ballast bed at any point, in particular in the four corners where the rail track and threshold intersect. It is then easily possible to irradiate the particularly heavily loaded areas below the rail track from all four sides with the two-component adhesive and thus to stabilize them optimally in the long term.
  • the method according to the invention differs from the method according to DE-A-43 04 776 primarily in that it is no longer necessary to raise the track grate consisting of rails and the sleepers firmly connected to them by 1 to 3 cm. It can therefore be used for the unchanged track grate. Furthermore, it differs in that the two-component adhesive is no longer introduced as a flat, curtain-like film in the cavity between the threshold and the ballast bed, but in the form of individual jets of the two-component adhesive. The result of this is that on the one hand no spray mist is formed, on the other hand these jets also seek a way through the ballast bed which penetrate a considerable distance into the ballast bed along the surface of ballast stones.
  • the previously used flat, curtain-like films tend to flow downward when they first hit gravel and stop penetrating the ballast bed in the direction of spray. Furthermore, the underside of the sleeper is not coated, or at least not completely, so that it maintains its frictional resistance to ballast.
  • the invention further relates to a device for performing the method consisting of
  • embodiments with a height-adjustable outlet head within a press-on protective chamber have the advantage that no changes need to be made to the control profile of the ballast.
  • the exit head can thus be inserted into the unchanged ballast bed at any depth. Darning, ballast clearing and track lifting can be omitted.
  • the two-component adhesives used are those as already described in EP-A-91 900 018. It is preferably a two-component adhesive which is set to have a relatively low viscosity and short pot lives. This ensures that the two-component adhesives can spread as a jet and wetting through a sufficiently thick layer of the ballast bed in order to finally harden so that the ballast stones only stick together at the points of contact.
  • the ballast bed as a whole remains open and able to drain surface water.
  • the device according to the invention for carrying out the method largely corresponds to the device according to EP-A-91 900 018, but instead of the flat jet nozzle, the outlet head described above is connected with one or more 0.5 to 3 mm holes. It is thus possible to carry out the method according to EP-A-91 900 018 with the same basic equipment and, after replacing the flat jet nozzle with an outlet head according to the invention, the method according to the invention for long-term stabilization of the heavily loaded areas of railway tracks. In this case, it can be entirely advantageous to carry out the process according to the invention first and then to treat the entire ballast bed in accordance with EP-A-91 900 018.

Abstract

L'invention a pour objet un procédé pour la stabilisation à long terme de tronçons de voies ferrées à fort trafic agencées sur un ballast, en particulier dans la zone se trouvant sous les traverses qui sont disposées sous le tronçon de voie et qui sont raccordées à celui-ci, caractérisé en ce qu'au niveau du bord inférieur de la traverse, un ou plusieurs cordons de 0,5 à 3 mm d'épaisseur, de préférence de 0,8 à 2 mm d'épaisseur, d'un agent adhésif à deux composants mélangés immédiatement avant l'emploi à 30 à 200 bar, sont extrudés à 2 à 15 bar, au moins une partie du/ou des cordons extrudés de l'agent adhésif étant dirigée spécifiquement dans la zone située sous la traverse. Le dispositif selon l'invention se différencie des dispositifs connus, par le fait qu'il comporte une tête d'extrusion munie d'un ou de plusieurs orifices de 0,5 à 3 mm, à travers lesquels les cordons de l'agent adhésif à deux composants mélangés préalablement avant l'emploi sont extrudés.
