Problems solved by technology

However, large-scale multi-storey overpasses are complex in structure, long in construction period, high in cost, large in floor area, and occupy a lot of space, so they are not suitable for the transformation of urban road traffic engineering at all.

Embodiment Construction

[0016] See figure 1 , the overpass of the present invention is a combined connection structure of passages in various directions, including passages on the ground or underground and overpasses above the ground; The upward right ramp 2 of the upward movement is forwardly connected with the roundabout 4 on the overpass, and the right direction is connected with the set right turn lane 3; Slope back road 8 is connected, and its inner road is connected with the left-turning downhill ramp 6 set to the left; each downhill backroad 8 in the forward straight direction is a left-turn downhill ramp in the left straight direction 6; A patio 7 is set between each left down ramp 6; the outer lanes of the roundabout 4 are located on the same horizontal plane; the functional walkway is formed in each direction of the forward, reverse, left, and right directions, and the structure on the overpass is the same ; A separation sign 5 is set between the inner and outer lanes of the roundabout 4 ;...

Abstract

The invention discloses a universal compact road overpass. In the invention, ascending right uphill roads (2) are arranged on the right side of a forward roadway (1) next to the overpass, the forward direction of the right uphill roads (2) are connected with interchange whirl roads (4), and the right direction of the right uphill roads (2) are connected with the arranged right turning roads (3); the external roadway of the whirl road is connected with the arranged downhill back roads (8) to a turning back direction; the inner road of the whirl road is connected with the arranged left turning downhill roads (6) to the left direction; the downhill back road on each direction is converged with left turning downhill roads on the overpass; and an open yard (7) is arranged among the left downhill roads. In the invention, motor vehicles and pedestrians can travel on respective way, with no need of stopping and waiting, thereby meeting smooth traffic and avoiding accidents, in addition, the universal compact road overpass has the advantages of little occupied floor area, little space usage and simple structure.

Description

technical field [0001] The invention belongs to the technical field of road overpass structures. Background technique [0002] Existing road, because motor vehicle and pedestrian increase in a large number, motor vehicle and pedestrian all will wait for signal light, often cause intersection, T-junction road traffic to travel slowly, even block up, block dead. And pedestrians cross the road, road traffic safety accidents often take place. In order to improve road traffic congestion, many cities have adopted measures such as prohibiting left turns, prohibiting U-turns, building overpasses, and controlling signal lights; it is also difficult to fundamentally solve road traffic congestion. The most effective measure to solve road traffic congestion in the world at present is to adopt the overpass structure. In order to meet the smoothness of the roads in all directions, most of them adopt a large-scale multi-layer overpass structure. The single-lane network cables are densely...
