Multifunctional cross-shaped overpass

Abstract

The invention discloses a multifunctional cross-shaped overpass, and belongs to road bridge buildings. The multifunctional cross-shaped overpass comprises a viaduct and two overpass bridges. The two overpass bridges are located on the two sides of the viaduct, and a transverse traveling bridge opening, a transverse crossing bridge opening and a longitudinal turning bridge opening are arranged at the bottom of a viaduct body; a turning leftward-turning bridge opening, a longitudinal crossing bridge opening and a transverse turning bridge opening are formed in the bottom of each overpass bridge; a transverse traveling lane penetrates the transverse traveling bridge opening from the bottoms of the viaduct; four rightward-turning bridges are arranged between the viaduct and the two overpass bridges, and turning leftward-turning bridges are arranged between the viaduct and the turning leftward-turning bridge openings in the bottoms of the two overpass bridges; two ports of the longitudinal turning bridge opening are communicated with a longitudinal traveling lane through longitudinal turning lanes on the two sides of the viaduct; and two ports of each transverse turning port are communicated with the transverse traveling lane through transverse turning lanes on the two sides of the overpass bridges. The multifunctional cross-shaped overpass has the beneficial effects of being simple in structure, small in occupied area, low in construction cost and high in practicability.

Description

technical field [0001] The invention relates to a road bridge building, in particular to a crossroad overpass which is composed of single-layer bridges and is provided with horizontal and vertical straight lanes, right-turn lanes, left-turn lanes and pedestrian passages. Background technique [0002] With the rapid development of urbanization, the number of people pouring into cities has increased sharply, and the population density is increasing; at the same time, with the development of the automobile industry, the number of automobiles in various cities is also increasing year by year. These two factors All have brought enormous pressure to the traffic of the city. In order to allow pedestrians and vehicles to pass in an orderly manner, road traffic in modern cities is usually managed by traffic lights. Generally speaking, traffic lights can play a certain role in regulating the orderly passage of pedestrians and vehicles, but in the case of a large flow of people and ve...

Problems solved by technology

[0006] In order to solve the problem that the slope of the overpass in the prior art is relatively large or the ramp is long, which makes it difficult for pedestrians to cross the road through the overpass and consumes a lot of physical strength, and the structure of the traditional crossroad overpass is complex, occupies a large area, and is difficult to build. Due to the problems of high cost and poor practicability, the present invention provides a multifunctional cross overpass, which includes a viaduct and two crossing bridges. The two crossing bridges are respectively located on both sides of the viaduct. , the longitudinal carriageway and the transverse carriageway are both two-way carriageways, and the bottom of the viaduct body is equipped with a transverse carriageway tunnel, two horizontal pedestrian bridge tunnels and two longitudinal U-turn bridge tunnels, and the two horizontal pedestrian bridge tunnels and the two longitudinal U-turn bridge tunnels are respectively in The two sides of the horizontal traffic bridge hole and the longitudinal U-turn bridge hole are located outside the horizontal pedestrian bridge hole; the bottom of the cross-street bridge is provided with a U-turn left-turn bridge hole, a longitudinal pedestrian bridge hole and a horizontal U-turn bridge hole, and the U-turn left-turn bridge hole and the horizontal U-turn bridge hole are respectively located at the sides of the horizontal pedestrian bridge hole. On both sides; the transverse traffic lane passes through the transverse traffic bridge hole at the bottom of the viaduct;
