Detailed description of the invention
Referring to accompanying drawing, inter-city passenger rail of the present utility model is described in detail with freely-supported mountain type beam.
Fig. 1 is the cross-sectional configuration schematic diagram of freely-supported mountain type beam for the inter-city passenger rail of the utility model the first embodiment. As shown in Figure 1, freely-supported mountain type beam for inter-city passenger rail of the present utility model, beam body is made up of the top flange plate 2,11 at limit web 8, median ventral plate 10 and the web top of base plate 5, bilateral symmetry setting. Base plate, dual-side web, median ventral plate are armored concrete or prestressed reinforced concrete construction. On base plate 5, be provided with track 6, train 7 passes through on track 6. Track 6 is two groups of uplink and downlink.
Inter-city passenger rail mountain type beam is two-wire beam, and uplink and downlink railway shares same beam body.
Inter-city passenger rail freely-supported mountain type beam span is between 15 ~ 40 meters.
Beam body inside is fixed with electric supply installation 1, traction change and power cable supporter 3 and communicates by letter and flashlight cable support body 4 along beam length direction. Power supply unit 1 is contact net system, and catenary mast is installed on both sides top flange plate 2, also can be arranged on top flange plate 11.
