Abstract

The invention discloses a road-rail dual-purpose bridge running in the same direction on the same floor. The bridge deck includes a railway line and a road lane. The right railroad lane of the line is adjacent to the left lane of the road lane. Using the road-rail dual-purpose bridge on the same floor of the present invention, the trains and cars on it are changed to run in the same direction, which greatly reduces the relative speed of the trains and cars, and avoids the extreme impact on the driver of the car when the trains and cars run in opposite directions. Great psychological impact and unfavorable glare, reduce the probability of traffic accidents, reduce the adverse impact of aerodynamic effects on cars when meeting cars, and improve the safety of road and rail traffic on the same-level road-rail dual-purpose bridge. The iron dual-purpose bridge has simple structure, clear concept, practical and convenient, and is easy to popularize.

Description

technical field [0001] The invention relates to the field of road transportation, in particular to a road-rail dual-purpose bridge running in the same direction on the same floor. Background technique [0002] With the rapid development of the national economy, the traffic flow has increased sharply. In recent years, the country has vigorously accelerated the construction of high-speed railways, expressways, urban municipal roads and urban rail transit. In order to save bridge site resources, reduce investment, and protect the environment, more and more bridges are constructed jointly by highways and railways (rail transit). Road-rail dual-purpose bridges include truss-type two-story road-rail dual-purpose bridges (such as the Nanjing Yangtze River Bridge), and there are also road-rail dual-purpose bridges with roads and railways on the same floor. [0003] However, in some countries, the road driving direction and the railway driving direction are opposite (such as in our ...
