Definitions

  • the invention relates to a ballastless track system for at least one railroad track consisting of two railroad tracks, especially for high-speed lines, - with a base course, a concrete slab and Reception facilities for the individual railroad tracks, the railroad tracks using rail fasteners in the reception facilities are attached, which are designed as rail base elements are, the rail base elements on have topsides in which the Rail fastening devices and fastened therein Rail feet of the individual railroad tracks arranged are, furthermore, the rail fastening devices and thus the rail feet with the help of rail fastening screws in the manner of sleeper screws into the rail base elements are screwed in are held in the cavities and wherein the base layer for receiving the static and dynamic loads is set up.
  • ballastless track system of which the invention is based (DE 23 54 958 B2) are on the Base layer with the interposition of a leveling layer Prefabricated concrete slabs up to 6 m long arranged, arranged in the longitudinal direction Receiving facilities for the individual railroad tracks and their rail fastening devices exhibit.
  • the reception facilities consist of the prefabricated concrete slabs and against the surface of the concrete pavement slabs increased contact surfaces for the rail fastening devices.
  • the known embodiment is sufficient not the tolerance requirements, in particular with High-speed lines have to be put what is based on the fact that large prefabricated concrete road slabs not to be laid with sufficient wadding can.
  • the known measures are also in manufacturing technology and assembly-technically complex.
  • ballastless track system (DE 23 54 960 B2), in which the concrete slab, those made in in-situ concrete or from prefabricated Elements can be composed of long-running Has grooves in the U-shaped at a distance from each other Receiving devices made of concrete are used, which the rail fasteners and the rails record, tape.
  • the invention is based on the technical problem ballastless track system for at least one railroad track indicate which easily manufactured with low tolerance can be and in particular meets all requirements, which are placed on high-speed lines have to.
  • the structure of the Base layer depends on the subsurface.
  • the Base layer has the required aggregates and is mostly cement bound.
  • the top of the two layers of the concrete pavement slab executed as a fiber-reinforced concrete layer. On this can cause uncontrolled cracking among the static, dynamic thermal loads in the top layer of the concrete slab can be prevented safely, so that the established Tolerances not due to uncontrolled crack formation deteriorate.
  • the ballastless superstructure system according to the invention is in In-situ concrete erected. You can rely on the proven manufacturing methods and manufacturing facilities of the modern Road construction can be used, namely on pavers for concrete roadways in road construction. Therefore, in Within the scope of the invention also of concrete carriageway slabs spoken.
  • the rail base elements are also concreted in, because corresponding aggregates in a standard paver can be easily installed can. Because the rail base elements are concreted they take shear loads in the direction of the track and across it without further ado, without impairing tolerance and corresponding transfers or Shifts have to be accepted.
  • the rail base elements be prefabricated, from a variety of different Materials.
  • the rail base elements made of in-situ concrete.
  • the invention teaches that the rail base elements made of in-situ concrete and in the manufacture of the concreted in the upper layer of the concrete carriageway slab are. It goes without saying that with one High strength concrete is being worked. From assembly technology Reasons regarding the assembly of the The invention recommends rail fastening devices the cavities with sloping cavity walls to provide and the rail fastening devices support it with complementary inclined surfaces.
  • the Concrete carriageway slab and possibly also the base course can be provided with a sound absorbing cover, from which only the excavation walls and the excavation floor stand out.
  • the sound absorbing cover can be made of rubber or plastic.
  • FIGS. 1 and 2 together explain a ballastless Track system for at least one railroad track consisting of two Rail tracks 1, which superstructure system in particular is set up for high-speed lines.
  • a base layer 2 a continuously manufactured concrete slab 3 and Recording devices 4 for the individual railroad tracks 1 are provided.
  • the railroad tracks 1 are with the help of rail fastening devices 5 in the Receiving devices 4 attached.
  • the concrete pavement slab 3 consists of two layers made on top of each other 6, 7, between which a reinforcement 8 from in the track direction longitudinal and transverse reinforcement bars is arranged.
  • the concrete of the concrete slab 3 is in the reinforcement mesh 9, the spaced Form reinforcement bars, cohesively, i.e. monolithic without joint, connected.
  • the reception facilities are as Rail base elements 4 executed in the upper Layer 7 of the concrete slab 3 and concreted Reinforcement components in the form of reinforcement loops 10 or reinforcement cages 11 in both layers 6, 7 of the Concrete slab 3 are anchored.
  • the rail base elements 4 have cavities on their top 12, in which the rail fastening devices 5 and the rail feet 13 of the individual fastened therein Rail tracks 1 are arranged.
  • ballastless superstructure system is the Base layer 2 to accommodate the static and dynamic Stresses set up. At least the top layer 7 of the two layers 6, 7 of the concrete slab 3 executed as a fiber-reinforced concrete layer.
  • the rail base elements 4 are together with the continuous Manufacturing of the entire ballastless track system made of in-situ concrete and in the manufacture of the top Layer 7 of the concrete slab 3 is concreted into this.
  • FIG. 1 indicates in rear part that the concrete slab 3 and also the base layer 2 with a sound absorbing Cover 18 are provided, from which only the Chamber walls 16 and chamber floor 19 stand out.
  • a formwork 20 which is set up and destined to manufacture of a track system according to the invention the rail base elements 4 to be made from in-situ concrete. It understands itself that the in-situ concrete in the formwork interior is introduced. In the exemplary embodiment it is already filled. He was hatched accordingly identified. It can be seen that reinforcement components in Form of reinforcement loops 10 in both layers 6, 7 of the concrete slab 3 are anchored in the Protrude inside the mold.
  • the formwork 20 supports Spring clips 21 dowels 15 for the threshold screws 14. Es is understood that after concreting the rail base elements 4 in the course of manufacturing the top Layer 7 of the concrete carriageway slab 3 the formwork elements be implemented. If one looks at FIG.
  • Fig. 6 illustrates that a ballastless according to the invention Track system in a simple, continuous manner can be manufactured.
  • the figure shows the scheme of a appropriate facility. The direction of work was indicated by arrows. You can see it on the left side 6 at the front end of the paver 25 Receiving funnel 26 for the concrete, which has suitable Facilities with marching paver 25 as a lower layer 6 or top layer 7 of the concrete carriageway slab 3 is introduced, lower layer 6 and upper layer 7 with a spatial and temporal distance.
  • the paver 25 is with a driver's cab 28 equipped, he has a base frame 29 through Trusses connected.
  • Installation of the concrete of the upper Layer 7 is carried out with a road smoothing device downstream 37.
  • a device 38 for impressing can also be seen the loop reinforcements 10 with which the Rail base elements 4 with the two layers 6, 7 of the concrete slab 3 are anchored.
  • reinforcement cages 11 are used, as shown in Fig. 4, so instead of the device 38 becomes a device connected to the concrete slab 3 initially introduces the undercut bores 22 and flushes them out or blows them into the reinforcement cages 11 are used if the already described Formwork 20 for the rail base elements 4 be positioned.
