Full interchange viaduct

Abstract

The invention provides a completely interchange type overpass, which consists of a ground layer and a viaduct, wherein the ground layer comprises two spanning motor vehicle lanes; a two-way ramp is arranged around a spanning point and is communicated with the adjacent motor vehicle lanes; ground non-motor vehicle lanes and sidewalks are sequentially arranged outside the two-way ramp and the motor vehicle lanes on the periphery of the two-way ramp; the viaduct consists of elevated non-motor vehicle lanes and elevated sidewalks outside the elevated non-motor vehicle lanes; the elevated non-motor vehicle lanes are connected with the ground non-motor vehicle lanes through elevated approach bridges; and a footbridge erected around the viaduct is used for connecting the ground sidewalks with the elevated sidewalks. The motor vehicle lanes, non-motor vehicle lanes and sidewalks of the completely interchange type overpass are in the respective own ways all the time, do not intervene each other, and have no intersection or conflict points. As the non-motor vehicle lanes and the sidewalks are arranged on the viaduct, construction cost is greatly reduced. The overpass has the advantages of simple construction and low cost, and is especially applicable to the road reconstruction of old cities.

Description

technical field [0001] The invention relates to an urban road crossing and intercommunication overpass, in particular to an all-round and complete intercommunication overpass. Background technique [0002] With the improvement of people's living standards and the development of the automobile industry, the number of automobiles has increased rapidly, which has brought enormous pressure to urban traffic. At present, the crossroads in the city are mainly based on traffic lights and traffic lights, which are inconvenient to pass, and the traffic jam phenomenon is becoming increasingly serious. [0003] Building flyovers is the fundamental way out to solve urban intersection congestion. But there are still some design deficiencies in the currently used overpass bridges, such as the cloverleaf type, ring, rhombus and other overpass bridges involved in "Road Crossing Planning Design and Construction" published by Heilongjiang Science and Technology Press, and The double-layer, t...

But there are still some design deficiencies in the currently used overpass bridges, such as the cloverleaf type, ring, rhombus and other overpass bridges involved in "Road Crossing Planning Design and Construction" published by Heilongjiang Science and Technology Press, and The double-layer, three-layer, and four-layer directional interchange bridges involved in the "Handbook of Highway Design Engineers" published by People's Communications Publishing House all use roads with different layers to divert and organize traffic flow, which has a large footprint and design problems. The height of the bridge affects the city appearance, the amount of engineering is large, the investment is large, it is difficult for motor vehicles to turn around after getting on the bridge, and the design is not humanized, etc.

In particular, these overpasses mainly consider the traffic intercommunication of motor vehicles, and take into account less for non-motor vehicles and pedestrians. Phenomenon, it has not been realized that people and vehicles go their own way and completely communicate with each other
