Abstract

Ballastless track for rail vehicles, comprising rails which are fixed to sleepers and which are carried by a civil engineering structure constructed from concrete or concrete composite, the sleepers (6) being cast into the structural concrete (16) of the civil engineering structure or into a protective concrete layer (10) or being mounted directly on the structural concrete (16) or the protective concrete layer (10).

Description

tracks are absent. In the cross-sectional plane, you can see the rods of the section of the longitudinal armature 8, as well as the transverse reinforcing rods that form the transverse armature.

Figure 2 shows the second embodiment of the invention, where the track components corresponding to the components of the first embodiment of the invention are marked with the same positions.

Unlike the first embodiment, in the bridge structure 9 (Fig. 2), the sleepers 6 are embedded in a protective concrete layer 10, which rests on the support structure 11 of the bridge structure 9. During the manufacture of the bridge structure 9, the first support structure 11 is made and then the cable channels 4 are assembled and the sides 5. The sleepers 6 are built into the trough-shaped cavities, respectively, between the cable channels 4 and the sides 5 in precisely set positions. Reinforcement 8 is laid in a similar way. The protective concrete layer 10 is made by pouring concrete. Protective concrete layer 10 also serves as bridge waterproofing.

Fig. 3 contains an enlarged view of a detail of the ballastless railway track shown in Fig. 2, with the protective concrete layer partially shown.

Two-block sleepers 6 are shown before pouring. Each pair of sleeper blocks 12, 13 is connected by mesh traverses 14, which also serve as transverse reinforcement. Between the mesh traverses 14, additional reinforcing rods 15 are installed transversely, similar to the rods of the longitudinal armature 8. After installing the sleepers 6 and the armature and giving them an exact position, concrete is poured in such a way that only the upper parts 16 of the two-block sleepers 6 protrude from the concrete layer.

Figure 4 shows a section of the third embodiment of the invention, as a ballastless railway track, in a tunnel.

Two-block sleepers would be directly embedded in the structural concrete 16 of the tunnel, that is, the ballastless railway track 17 forms a single unit with the structural concrete 16 of the tunnel. In the cross-sectional plane, the rods of the longitudinal reinforcement 18 are visible. The absence of additional or separate track panels makes it possible to reduce the diameter of the tunnel.

If the ballastless railway track 17 is made in a tunnel, the two-block sleepers 6 are first installed and accurately positioned, and then structural concrete 16 is poured. Fig. 5 shows another embodiment of the invention as a ballastless railway track in a tunnel.

Unlike the embodiment shown in Fig. 4, this embodiment provides a compensatory concrete layer 19 in which sleepers 6 are embedded. Under the compensatory concrete layer 19 is a concrete layer 20 in the form of a segment of a circle. Thanks to this, the forces created during the operation of the ballastless railway track are directly transmitted to the soil forming the tunnel. r I 7 " chi B t ne, ! liu x
