Half-storey ultra-compact overpass unit

Abstract

A half-storey ultra-compact overpass unit relates to the technical field of overpass systems and comprises a plurality of half-storey ultra-compact overpasses. Each half-storey ultra-compact overpass comprises an upper overpass face and a lower overpass face which are intersected, the lower overpass face is concaved and arranged under a horizontal road surface, and the upper overpass face is convex and arranged above the lower overpass face in an erected mode. The half-storey ultra-compact overpass unit is characterized in that an isobathic area is arranged in the intersected area of the upper overpass face and the lower overpass face, right turn bridges for turning right are respectively arranged at four turning corners intersected by the upper overpass face and the lower overpass face, two ends of each right turn bridge are in gradual change shapes and respectively connected onto right turn lanes of the upper overpass face and the lower overpass face. The half-storey ultra-compact overpass unit has the beneficial effects of being low in construction cost and wide in application range, not only effectively relieving traffic condition of jammed road intersections of big cities, but also greatly reducing the influence on neighboring environment of the overpass unit.

Description

technical field [0001] The invention relates to the technical field of overpass systems, in particular to an ultra-compact half-storey overpass unit with low cost, complete functions and greatly reduced impact on the surrounding environment. Background technique [0002] The rationality of urban road system design in urban planning will play a positive role in promoting the rapid development of the city. However, the increasing number of automobiles has brought more and more serious congestion to the road traffic in cities. In order to alleviate the congestion of road traffic in the city, people began to use various methods to organize and control the traffic order, such as: setting up tunnels or overpasses at crossroads, so that motor vehicles and non-motor vehicles running north-south and east-west And pedestrians can pass smoothly. This kind of traffic system is mainly applicable to express arterial roads in cities, and cannot popularize and solve the traffic organizati...

AI Technical Summary

Problems solved by technology

Although this commonly used urban road traffic organization system has many advantages such as low cost, convenient implementation and traffic, it also has certain deficiencies: 1. The waiting time for traffic is too long

When non-motor vehicles turn left, they are sandwiched between motor vehicles that turn left and turn left in the opposite direction, which can easily cause traffic safety accidents; 3. It is difficult for motor vehicles to turn around

When a motor vehicle needs to turn around at an intersection, due to the limited space and the vehicles coming from the opposite direction in the straight direction, it is difficult to make a U-turn on the spot, and often causes traffic jams in the opposite direction in the straight direction
