Problems solved by technology

The overpass is to make the vehicles go their own way in the way of three-dimensional intersection to ensure the unimpeded intersection. However, the tall and complex overpass has the disadvantages of occupying a large area, high cost, affecting the landscape, etc., so it is rarely used so far.
Objectively analyze the characteristics of traffic flow in real urban areas. Cars and small cars account for about 60-70%, ordinary large passenger and large trucks account for up to 30%, and special ultra-high vehicles rarely drive in urban areas, but the technical standards for overpasses and even bridges we built They all take super-high vehicles to pass as

Embodiment Construction

[0015] In the implementation of the low auxiliary span and short slope road crossing bridge with variable main span height, it can be designed and built as a ground bridge, semi-submerged in the Ground bridge or fully submerged bridge, the building materials, modeling style and lifting or opening type of the bridge can also be selected and determined according to the specific situation, so that the appearance of the bridge and the surrounding environment can be harmoniously unified to add beauty to the city .

[0016] Fig. 7 is an example of the design of a road crossing bridge with low auxiliary span and short slope with variable main span height on semi-submerged ground actually applied to urban road intersections. The semi-submerged bridge has the strongest adaptability because it occupies a small area, and most of the existing intersections can accommodate it; It can be converted into a pedestrian bridge or tunnel at particularly busy intersections. Low auxiliary span an...

Abstract

The present invention relates to a main span depth variable lower secondary span short slope road overpass bridge. It is a road overpass bridge constructed by utilizing main crosshole and making it be connected with lower secondary crosshole and short bridge grade section. Said main crosshole is equipped with a device capable of making bridge be heightened and opened. Said road overpass bridge can completely solve the problem of urban traffic block.

Description

field of invention [0001] The invention relates to an improvement of a road crossing bridge. Especially the low auxiliary span and short slope road span bridge with variable main span height. technical background [0002] The development and rapid increase of automobiles make road traffic the bottleneck of urban development, and road intersections are the key to smooth traffic. In the prior art, traffic lights and overpass bridges are used to guide traffic at city road intersections. Red and green traffic lights alternately block traffic in a certain direction to guide traffic. Once the waiting time for vehicles to pass through the intersection exceeds the gap alternate time, congestion will occur. The overpass is to make the vehicles go their own way in the way of three-dimensional intersection to ensure the unimpeded intersection, but the tall and complex overpass has the disadvantages of occupying a large area, high cost, affecting the landscape, etc., so it is rarely u...
