multifunctional overpass

Abstract

The invention discloses a multifunctional flyover, which is characterized by comprising a lower annular lane, a first straight channel, a second straight channel, non-motorized vehicle lanes and a flyover surface, wherein the second straight channel intersects with the first straight channel; the four non-motorized vehicle lanes are positioned in included-angle areas between the first straight channel and the second straight channel respectively; each non-motorized vehicle lane is provided with two branch non-motorized vehicle lanes which are connected to the non-motorized lanes on the first straight channel and the non-motorized lanes on the second straight channel; the flyover surface is correspondingly formed over the first straight channel and the second straight channel. Compared with the prior art, the multifunctional flyover has the advantages that the traffic pressure is relieved by separating large vehicles from small vehicles; the large vehicles go through the flyover surface while most small vehicles go through from ground trunk roads, and the overall traffic is smooth without traffic light control, so that the current situation of traffic jam can be relieved effectively.

Description

technical field [0001] The invention relates to a traffic road facility, in particular to an overpass. It belongs to the technical field of construction engineering. Background technique [0002] Urban traffic congestion is a common problem in the world today. With the development of our country's economy, traffic congestion in some cities in our country is becoming more and more serious. Although measures have been taken, the fundamental problem has not been solved, so the effect is not very satisfactory. The so-called fundamental problem is exactly the intersection of the planes of the crossroads, and vehicles must stop here, and congestion is inevitable. But if all build overpass bridge at every intersection according to common way, not only cost is too high, and because bridge body is very high, thereby approach bridge is too long. In the central area of ​​the city, the distance between the roads is often less than the length of the approach bridge. And because of its...

Problems solved by technology

Moreover, due to its high bridge body, it does not match certain architectural styles in the city, and it does not solve the problems of pedestrians and straight vehicles crossing the road.

[0003] For this reason, many people have proposed a lot of improved overpasses, such as the Chinese utility model patent "Full Interoperable Runway Overpass" (authorization announcement number is CN201377071Y) that is the Chinese utility model patent of ZL200920018312.X as the patent number; Invention patent "Interchange Overpass" (authorized announcement number CN102363943B), etc.; when the above-mentioned prior art solves traffic congestion, it does not take into account the distinction between large vehicles and small vehicles
