Man-vehicle-layered interchange type overpass

Abstract

The invention discloses a man-vehicle-layered interchange type overpass. The man-vehicle-layered interchange type overpass comprises a transverse bridge and a longitudinal bridge which allow dual-way traveling to be achieved; the transverse bridge and the longitudinal bridge each comprise a lane A and a lane B, wherein each lane A comprises a left-handed rotation way, a direct way and a right-handed rotation way; and the lanes are intersected to form a low layer and a high layer. The man-vehicle-layered interchange type overpass further comprises a cross-shaped sidewalk arranged on the ground. According to the man-vehicle-layered interchange type overpass, the lanes for different vehicles are singly arranged and are in different running directions, all the lanes are not intersected and not influenced with each other, and man-vehicle layering is achieved; and the bridge approaching length is short, the floor space is small, the manufacturing cost is low, the traffic efficiency and the safety performance are high, and the man-vehicle-layered interchange type overpass can be widely built and applied to crossroads of cities.

Description

technical field [0001] The invention relates to the field of road and bridge construction, in particular to an interchange type overpass with layers of people and vehicles. Background technique [0002] With the rapid increase of urban population and the increasing number of vehicles, people's demand for the development of urban road construction and transportation is increasing. Building overpasses at crossroads is a good means to improve vehicle congestion. However, the overpasses in the prior art have difficulty in diverting people and vehicles, occupy a large area, have long approach bridge lengths, high manufacturing costs, difficult to identify directions, frequently staggered lanes, and lack Disadvantages such as U-turn reverse and left turn. [0003] The utility model with the Chinese application number of 2012203500072 is a crossroad overpass, which includes a first vehicle arch bridge and a second vehicle arch bridge interlaced together, the first vehicle arch bri...

AI Technical Summary

Problems solved by technology

Although this invention solves the technical problems that the direction of the ramp is difficult to identify and the diversion of people and vehicles is difficult, it has the following defects: First, the overpass does not have separate lanes for motor vehicles and non-motor vehicles, and the mixed traffic of motor vehicles and non-motor vehicles causes mutual intersection impact, especially when vehicles turn left and right, it is very easy to cause congestion and traffic accidents; secondly, the overpass has no U-turn lanes, which cannot meet the needs of driving vehicles, and the intercommunication performance of the overpass is poor; in addition, the overpass has four floors in total. If the turning ramp is directly connected to the right side of the horizontally arranged straight road, the right turning ramp should be set at least 12m high under the condition of ensuring the height of passing vehicles, resulting in high overall height of the overpass, long approach bridge, large floor area and high manufacturing cost; in addition , the interchange does not have a U-turn lane, it is troublesome and takes a long time for vehicles to turn around
