A kind of continuous U beam urban track traffic for, this U beam is continuous structure, by the end bay at two ends and centre one orIn multiple, across composition, end bay and middle bridging are integral, and the outer end of two end bays is supported by abutment pier; End bay and in across connectionPlace, and in adjacent two across junction supported by middle pier; Web and web that the beam body of U beam is arranged by base plate, bilateral symmetryThe top flange plate composition at top is connected with the track of single line or two-wire on base plate, along beam length direction be fixed with electric supply installation,Traction becomes and power cable supporter, communication and flashlight cable support body, and traction becomes and power cable supporter is placed in webInner side cable bearer on or be placed on base plate, communication and flashlight cable support body are placed on base plate or are placed in the inner side of webOn cable bearer; Top flange plate top is fixed with sound barrier or pedestrian guardrail.
Described end bay and in across span all between 15 ~ 40 meters.
Described power supply unit is the three rail power supply units that are fixed on base plate, or is arranged on the contact on top flange plateNet.
The width of described top flange plate is 0.5 ~ 1.5 meter.
Advantage and the good effect that the utlity model has are:
Continuous U beam for urban track traffic of the present utility model, adopts continuous U beam construction, utilize backplanes support track andTrain, reduced bridge get on the right track absolute altitude and circuit whole height, and it is good to have anti-acoustic capability, has reduced the shadow to surrounding enviromentRing, anti-train falls, and bridge security is good, structure can doublely be done the advantages such as the attached structure of bridge floor, more than beam length can reach 300m simultaneously, and canMeet switch area and do not establish the requirement at expansion joint, be applicable to the Continuous Bridge of 15 ~ 40 meters of left and right of urban track traffic, particularly circuitWhile being positioned at small curve radius or on bridge, have the situation of track switch, and comprehensive economy is good, practical, has before more wide applicationScape.

Detailed description of the invention
Referring to accompanying drawing, urban track traffic of the present utility model is described in detail with the continuous U beam of two-wire.
Fig. 1 is the cross-sectional configuration schematic diagram of the continuous U beam of urban track traffic of the present utility model single line; Fig. 2 is thisThe cross-sectional configuration schematic diagram of the continuous U beam of two-wire for the urban track traffic of utility model; As depicted in figs. 1 and 2, this practicality is newThe continuous U beam of two-wire for the urban track traffic of type, the web 8 that beam body is arranged by base plate 5, bilateral symmetry and web 8 tops upperFlange plate 2 forms. Base plate and two coxostermums are armored concrete or prestressed reinforced concrete construction. On base plate 5, be provided with support railPlatform 6, train 7 passes through on track 6. When two-wire, track 6 is right for uplink and downlink two, and two-wire track traffic shares a beamBody, when single line, track 6 is one group.
Beam body inside is fixed with electric supply installation 1, traction change and power cable supporter 3 and communicates by letter and signal along beam length directionOptical cable supporter 4. Power supply unit 1 is three rail power supply units fixing on base plate 5, also can adopt contact net power supply, contact netPillar stands on top flange plate 2. Traction becomes and power cable supporter 3 is placed on the inner side cable bearer of web 8 or is placed at the endOn 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.
The top of top flange plate 2 and adjacent simply supported beam fire escape top are contour, can be used as fire escape and access path. ?Platform place, top and the platform floor of top flange plate 2 are contour, facilitate passenger getting on/off.
The width of top flange plate 2 is 0.5 ~ 1.5 meter, and top flange plate 2 tops are fixed with sound barrier or pedestrian guardrail 9.
Fig. 3 is the vertical structure schematic diagram of the continuous U beam of urban track traffic of the present utility model two-wire. As shown in Figure 3,The continuous U beam of two-wire for urban track traffic of the present utility model, longitudinally upper is continuous structure, by the end bay 10 at two ends and middleIn one or more across 11 compositions, end bay 10 and in be integrally formed across 11, end bay 10 and in all can be 15 ~ 40 across 11 spanRice, concrete ratio between side span and main span can be adjusted as the case may be. The outer end of two end bays 10 is supported by abutment pier 12. End bay 10 and in across11 junction, and in adjacent two, the junction across 11 is supported by middle pier 13. End bay 10 be generally 2 across, in across 11 can be 0 ~10 across, specifically can adjust as required, the number of middle pier 13 is corresponding adjustment also.
The continuous U beam of two-wire for urban track traffic of the present utility model, noise reduction is good, utilize backplanes support track and rowCar, has reduced bridge get on the right track absolute altitude and circuit whole height, has reduced the impact on surrounding enviroment, can prevent derail simultaneouslyAfter go out bridge, be applicable to the Continuous Bridge of 15 ~ 40 meters of left and right of urban track traffic, when particularly circuit is positioned at small curve radiusOr on bridge, there is a situation of track switch.
The utility model adopts continuous U beam construction, has that common freely-supported U beam building height is low, good, the anti-train of noise abatement performanceFalling, bridge security is good, structure can doublely be done the advantages such as the attached structure of bridge floor, more than beam length can reach 300m simultaneously, can meet switch areaDo not establish the requirement at expansion joint, be also applicable to the circuit situation of small curve radius, and comprehensive economy is good, practical, hasWide application prospect.
