Urban railway viaduct section structure

Abstract

The invention discloses an urban railway viaduct section structure. The urban railway viaduct section structure comprises a track beam (2) arranged at the top of a box girder (1) and further comprisesa strong current cable trench (6) and a weak current cable trench (7), wherein the strong current cable trench (6) and the weak current cable trench (7) are arranged inwards from the two sides of thetransverse direction of the box girder (1) in sequence; an overhead contact system upright (4) and acoustic barrier uprights (8) are arranged in the strong current cable trench (6); the overhead contact system upright (4) is arranged between the two adjacent acoustic barrier uprights (8); the cross section of the overhead contact system upright (4) and the sections of bottom foundations of the acoustic barrier uprights (8) have one section of overlapped parts in the longitudinal direction; a signal machine (10) is also arranged in the position, close to a track side trench wall, of the strongcurrent cable trench (6); and the signal machine (10), the acoustic barrier uprights (8) and the overhead contact system upright (4) are staggered with each other on different transverse sections. According to the urban railway viaduct section structure, the bridge floor space is sufficiently utilized, and the arranging problem of each system equipment structure of urban railway within a relatively smaller bridge floor width range is solved.

Description

technical field [0001] The invention belongs to the technical field of urban railway elevated sections, and more specifically relates to an urban railway elevated section structure. Background technique [0002] Urban railway, also known as urban rail transit, is an urban public rail transit system based on railway technology and equipment that is specially operated between adjacent cities and urban areas. Rapid and large-capacity public transportation in satellite towns or urban circles. The operating speed of urban railways is generally between 120 and 200km / h, and the distance between stations is relatively small. With moderate characteristics, it can also realize the interconnection with the national main railway line and enhance the city's ability to radiate to the outside world. [0003] The urban railway system currently operates Shanghai Jinshan Intercity Railway, Yuyao Intercity Railway, etc. The above two lines do not have a separate urban railway line, and both ...

AI Technical Summary

Problems solved by technology

In addition, the Shanghai Jinshan City Railway and the Yuyao Intercity Elevated Section adopt the National Railway Line, and the bridge width is 12.6m, but the bridge width of the City Railway is relatively narrow. At present, there is no elevated section structure suitable for the narrow bridge of the City Railway
