Detailed description of the invention
Referring to accompanying drawing, inter-city passenger rail two-wire freely-supported U beam of the present utility model is described in detail.
Fig. 1 is the cross-sectional configuration schematic diagram of the inter-city passenger rail two-wire freely-supported U beam of the utility model first embodiment.As shown in Figure 1, the inter-city passenger rail two-wire freely-supported U beam of the first embodiment, beam body is made up of base plate 5, the web 8 of bilateral symmetry setting and the top flange plate 2 at web 8 top.Base plate and two coxostermums are steel concrete or prestressed reinforced concrete construction.Base plate 5 is provided with track 6, and train 7 passes through on track 6.Track 6 is uplink and downlink two groups.
Inter-city passenger rail U beam is two-wire beam, and uplink and downlink railway shares same beam body.
Inter-city passenger rail two-wire freely-supported U beam span is between 15 ~ 40 meters.
Beam body is inner to be fixed with electric supply installation 1, traction change and power cable supporter 3 and to communicate and flashlight cable support body 4 along beam length direction.Power supply unit 1 is contact net system, and catenary mast is installed on top flange plate 2.On the inner side cable bearer that traction becomes and power cable supporter 3 is placed in web 8 or be placed on base plate 5, communication and flashlight cable support body 4 are placed on base plate 5 or are placed on the inner side cable bearer of web 8.
