Problems solved by technology

In urban areas, road intersections are densely populated with busy traffic, but the existing pedestrian-vehicle interchanges are usually erected in multiple layers and connected to multiple overhead ramps, which not only have a huge volume, engineering and cost, but also make pedestrians and vehicles difficult. It is cumbersome and inconvenient, so although there is a demand for bustling and lively road intersections in cities, it is difficult to accommodate and rarely used
The Chinese patent "Straight-span and flat-turn urban interchange intersection" (200410067097.4; 200420090955.2) is designed and applied with the combination of straight-span bridge and flat ramp to effectively simplify the road three-dimensional intersection. However, there are still more inconveniences and conflicts in the application of pedestrians crossing intersections in downtown areas.

Embodiment Construction

[0015] During the implementation of low-span and high-span passages crossing the intersections separately, underground, semi-underground or above-ground types can be selected according to the specific conditions of road intersections. The underground or semi-underground types have little impact on the environmental landscape, and shallow crossings are used to reduce the scale Generally canalized intersections can be accommodated. In urban areas where trucks are restricted from entering the city, low-span and high-level crossing passages can be set at the elevation that only urban buses can pass, so as to reduce the length of ramps and reduce the size of the overpass to reduce construction costs. If the non-motor vehicle and motor vehicle passages are separated or constructed separately, not only the span width of the motor vehicle passage can be reduced, but also the span height of the non-motor vehicle passage can be reduced to reduce the slope. During implementation, pedestr...

Abstract

The present invention provides a new design precept of low-span high-passageway separated through-intercommunication road intersection. Said design precept is aimed at resolving the urban traffic blockage problem. Said invention also provides the concrete structure of said road intersection and its concrete construction scheme and method.

Description

technical field [0001] The invention belongs to an improvement of a crossroad intersection, in particular to a low-span and high-level passage separated and crossing an interworking intersection. technical background [0002] The development of human economy and technology makes automobiles more and more involved in social production and life, which brings busyness and congestion to urban road network traffic. In the prior art, urban road intersections also often adopt level intersections when the management of signal lights cannot adapt to the busy flow of people and vehicles. Existing level intersections are provided with individual constructions for pedestrians or traffic, such as pedestrian crossing overpass tunnels and express arterial overpasses, etc., as well as pedestrian traffic A merged three-dimensional intersection. In urban areas, road intersections are densely packed with pedestrians and vehicles, but the existing pedestrian-vehicle interchanges are usually er...
