Ultralow-altitude complete intercommunicating interchange system for U-turn in road section

Abstract

Relating to the technical field of interchange systems, the invention provides an ultralow-altitude complete intercommunicating interchange system for U-turn in a road section. The system includes a plurality of ultralow-altitude complete intercommunicating interchange systems, each of which comprises an upper bridge deck and a lower bridge deck that intersect. The lower bridge deck is concavely arranged below a level road surface, and the upper bridge deck is convexly arranged over the lower bridge deck. Four corners where the upper bridge deck and the lower bridge deck intersect are equipped with right turn bridges special for turning right, with the right turn bridges communicated with the upper bridge deck and the lower bridge deck. In-situ U-turn systems are disposed among the plurality of ultralow-altitude complete intercommunicating interchange systems. The interchange system of the invention has the beneficial effects of: low construction cost, small environmental influence, and wide application scope. The system can be applied in interchange transformation of heavy-traffic intersections in large cities, and is also suitable for construction of new road networks in urban development zones.

Description

technical field [0001] The invention relates to the technical field of overpass systems, in particular to an ultra-low-altitude full-interchange overpass system with low cost, good time efficiency, and a U-turn in road sections that can greatly reduce the impact on the 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 po...

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 a non-motorized vehicle turns left, it is sandwiched between motorized vehicles that turn left and reversely, which can easily cause traffic safety accidents; 3. It is difficult for motorized 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
