Urban multilayer roundabout viaduct

Abstract

The invention discloses an urban multilayer roundabout viaduct, comprising top-layer multi-direction small car lanes, middle-layer multi-direction small car lanes located at two sides of the top-layer multi-direction small car lanes and multi-direction road surface driving lanes located below the middle-layer multi-direction small car lanes, wherein the intersection center of the top-layer multi-direction small car lanes and the middle-layer multi-direction small car lanes is connected with a double-layer roundabout viaduct, the top-layer multi-direction small car lanes are parallel bidirectional small car lanes and are connected with a corresponding top-layer roundabout viaduct, the middle-layer multi-direction small car lanes are bidirectional small car lanes and are connected with parallely arranged transition bridges through approach bridges with certain angles and then connected with a roundabout viaduct module, and the multi-direction road surface driving lanes comprise straight and right-turn large car lanes, left-turn waiting lanes of branch roads and bicycle lanes. Since the urban multilayer roundabout viaduct is rapidly assembled into an integral body from steel structure modules, the urban multilayer roundabout viaduct has the advantages of small investment, a short construction cycle and no influence on normal traffic on the road during installation.

Description

technical field [0001] The invention relates to the field of urban road traffic. Specifically, it is a multi-layer ring island type three-dimensional bridge for rapid transformation of urban level crossings. Background technique [0002] At present, with the continuous acceleration of urbanization and the continuous improvement of people's living standards, the large increase of motor vehicles, especially private cars (small cars), has brought about urban road traffic congestion, which has become a major problem that affects and plagues urban traffic. Especially in the most prosperous area of ​​the city, it is also the most congested road section. It is a highly concentrated area of ​​vehicles, pedestrians, and commercial shops. Many cities have invested in the construction of a large number of overpasses or underground passages to solve the problem of crossing pedestrians and motor vehicles. However, due to Due to non-motor vehicles and people's living habits, the effect o...

Problems solved by technology

Especially in the most prosperous area of ​​the city, it is also the most congested road section. It is a highly concentrated area of ​​vehicles, pedestrians, and commercial shops. Many cities have invested in the construction of a large number of overpasses or underground passages to solve the problem of crossing pedestrians and motor vehicles. However, due to Non-motor vehicles and people's living habits have little effect on alleviating congestion

If a conventional overpass is built to allow vehicles to go their own way, it is limited by the existing space, and if the area of ​​the intersection area is expanded, it will face difficult demolition work and high compensation costs

Many expressways and elevated roads under urban construction are also blocked due to congestion at downlink intersections. A large number of vehicles idle for a long time and wait at each congested intersection, causing serious environmental pollution and waste of energy.
