Bridge tunel combined crossing road on different level for crossroads

Abstract

The invention relates to crossroad bridge tunnel combining elevated crossing. Its features are that the upside of the crossing road surface is set viaduct connected between southern and northern crossings; its down side is set subterranean tube connected between southern and northern crossings; the viaduct and the subterranean tube are single direction lane whose travel direction are opposite. The viaduct, subterranean tube, crossroad ground floor lane are formed one vertical plane three-layer traffic hinge switching center. The vehicle form each direction can directly pass the crossroad without obstacle crossing. The travel direction and route are intuitive, and have good safe performance.

Description

Technical field: [0001] The invention relates to a three-dimensional traffic hub exchange center, more specifically to an overpass suitable for crossroads. Background technique: [0002] With the rapid development of the economy, there are more and more various vehicles, which have caused great pressure on road traffic. In order to alleviate the pressure on traffic, people have built various overpasses. In the prior art, there are butterfly overpasses, lotus overpasses, and elevated overpasses. Although they have played a good role in dredging and shunting the vehicles, they all occupy a large area and are expensive. Moreover, the structure of each bridge is different, especially the left turn problem. The left turn of the vehicle has always been realized by circling to the right. Once the driver who is not familiar with the structure of the overpass gets on the bridge, he will not be able to tell the difference between the south, the east and the north, and it is difficult...

AI Technical Summary

Problems solved by technology

The left turn of the vehicle has always been achieved by circling to the right. For drivers who are not familiar with the structure of the overpass, once they get on the bridge, they will not be able to tell the difference between the south, the east and the north, and it is difficult to get off the bridge smoothly.
