Described power supply unit is contact net system, can be arranged on top flange plate, also can be arranged on horizontal baffle.
The width of described top flange plate is 0.5 ~ 1.5 meter, and the difference in height between the end face of top flange plate and the end face of horizontal baffle is 1 ~ 2 meter.
End face and the platform floor of described top flange plate are contour, facilitate passenger getting on/off.
The advantage that the utility model has and good effect are:
Inter-city passenger rail box U beam of the present utility model, beam body torsional rigidity is large, noise reduction good, reduce the impact on surrounding enviroment, utilize median septum supporting track and train, reduce bridge to get on the right track absolute altitude and circuit whole height, after derail being prevented, go out bridge simultaneously, be applicable to inter-city passenger rail span and be not more than the continuous structure bridge that the freely supported structure of 65 meters or main span are not more than 180 meters.
The utility model can overcome the particular limitations of two kinds of beam type such as deck type case beam and lower support type U beam, and effectively combines the advantage of two kinds of beam type.Of the present utility model rational in infrastructure, comprehensive economy is good, practical, has more wide application prospect.
