Embodiment 1

[0040] figure 1 The structural representation of the overpass provided for the embodiment of the present invention, as figure 1 As shown, this embodiment provides an overpass, including: longitudinal lanes and transverse lanes intersecting each other. The overpass in this embodiment is preferably used at intersections, and the lanes connecting opposite intersections are longitudinal lanes and transverse lanes respectively. Longitudinal lanes and transverse lanes cross each other but are not connected.

[0041] The longitudinal lanes include the first ground lane and the first bridge deck lane. The first ground lane is the lane directly laid on the ground, and the first bridge deck lane is the lane that needs to be lifted off the ground or needs to be dug to pass through the ground. Lanes, wherein the first ground lane includes the first left-turn lane 1 and the second left-turn lane 2 entering the adjacent intersection, and the radius of the first left-turn lane 1 and the sec...

Embodiment 2

[0058] like image 3 As shown, in another specific embodiment of the present invention, on the basis of Embodiment 1, the first left-turn lane 1 and the fourth right-turn lane 16 have some road sections connected, and the second left-turn lane 2 and the second right-turn lane Route 14 is partially connected. The vehicle traveling on the first left turn lane 1 can enter the fourth right turn lane 16 through the part communicating with the fourth right turn lane 16, so that the vehicle can turn around and travel back to the first intersection 3; or in the fourth right turn lane Vehicles traveling on 16 can enter the first left-turn lane 1 through the part communicating with the first left-turn lane 1 , so that the vehicles can turn around and travel back to the third intersection 7 .

[0059] In the same way, vehicles traveling in the second left-turn lane 2 can drive back to the second intersection 4 through the part communicated with the second right-turn lane 14, or vehicles...

Embodiment 3

[0062] like Figure 4 As shown, in a specific embodiment of the present invention, on the basis of Embodiment 1, the overpass further includes a first circular bridge 17 , a second circular bridge 18 , a third circular bridge 27 and a fourth circular bridge 28 . Wherein, the entrance and the exit of the first circular bridge 17 communicate with the first left-turn bridge 11 and the first left-turn lane 1 respectively, and the first circular bridge 17 bypasses the third straight bridge 9 and the fourth straight bridge 10; The entrance and exit of the second circular bridge 18 communicate with the second left-turn bridge 12 and the second left-turn bridge 2 respectively; the entrance and exit of the third circular bridge 27 communicate with the first left-turn lane 1 and the second left-turn bridge 12 respectively , the entrance and exit of the fourth circular bridge 28 communicate with the second left turn lane 2 and the first left turn bridge 11 respectively; 10; the third ci...

Abstract

The invention provides an overpass bridge. The overpass bridge comprises a longitudinal lane and a transverse lane which are intersected. The longitudinal lane comprises a first ground lane and a first bridge floor lane. The first ground lane comprises a first left-turn road and a second left-turn road which enter two adjacent intersections, the first bridge floor lane comprises a first straight-going bridge and a second straight-going bridge which communicate with a first intersection and a second intersection, wherein the lane directions of the first straight-going bridge and the second straight-going bridge are opposite, and the transverse lane comprises a first left-turn bridge, a second left-turn bridge, a third straight-going bridge and a fourth straight-going bridge, wherein the third straight-going bridge and the fourth straight-going bridge communicate with a third intersection and a fourth intersection; and the first left-turn bridge communicates with the third straight-going bridge at the third intersection, the first left-turn bridge communicates with the first straight-going bridge at the second intersection, the second left-turn bridge communicates with the fourth straight-going bridge at the fourth intersection, and the second left-turn bridge communicates with the second straight-going bridge at the first intersection. According to the overpass bridge, the structure is compact, the occupied space is small, the first left-turn road and the second left-turn road are directly paved on the ground, and the construction difficulty and the construction cost are reduced.

Description

technical field [0001] The invention relates to the technical field of road building design, in particular to designing an overpass. Background technique [0002] The structural forms of highway overpasses are various, especially the structural forms of highway crossroad overpasses are ever-changing. The currently built highway crossroad overpasses are composed of one or more vehicles respectively or simultaneously. Vehicle left-turning overpass ramp, vehicle right-turning overpass ramp, vehicle U-turning overpass ramp, vehicle up and down bridge spiral ramp and overpass circular ramp, etc. Various overpass ramps are combined in different forms at crossroads to form various vehicles and pedestrians. Function. [0003] At present, among the various highway crossroad overpasses that have been built at home and abroad, there are full functions of vehicle traffic, that is: there are not many crossroad overpasses that allow vehicles coming to the crossroad from all directions to...
