Problems solved by technology

Such overpass bridges with too high bridges and too long ramps bring many disadvantages to the driving of motor vehicles, and occupy a large area, especially in urban areas, which face many demolition and relocation difficulties, high compensation funds, and difficult operation and implementation.
However, if the overhead turntable overpass is used, due to the continuous interweaving of turning vehicles and circular vehicles, the increase in traffic flow will easily cause traffic "locking".

Embodiment 1

[0020] As shown in Figure 1, the overpass is set at the crossroads, and the crossroads are divided into four main line intersections: up, down, left, and right, where the up and down direction is the main road 1 with a large traffic flow, and the left and right directions are the crossed road 3. Consistent with the level of the main road surface and connected at four intersections. The main line road 1 going straight through the overpass is a curved arch separation bridge 2. The height of the above-mentioned curved arch separation bridge 2 is the highest at the intersection of the main line road 1 and the horizontal projection of the crossed road 3, and the curved arch separation bridge 2 is from the highest point up and down. The direction adopts the ramp to gradually descend until it connects with the main road surface in direction 1 of the main road. There are half-slope overhead abutments 8 respectively on the crossed roads 3 in the left and right directions on both sides ...

Embodiment 2

[0032] Because the ramp length of the curved arch separation bridge 2 should meet the regulations on the slope of the automobile road, the space height distance between the arc section 25 of the U-shaped ring road 24 and the curved arch separation bridge 2 will be guaranteed again, so the U-shaped ring road The length of 24 just needs to be longer, in order to shorten the length of U-shaped ring road 24, carry out partial modification on the structure of embodiment 1, as shown in Figure 2, be about to the height that the arc section 25 of U-shaped ring road 24 builds exceeds The height of the connection platform 23 makes the upper and lower U-shaped ring roads 24 combined to form a saddle shape like riding on the main road 1 . For this reason when entering the U-shaped ring road 24 from the connection platform 23, it is an uphill, and it is a downhill from the U-shaped ring road 24 to enter the connection platform 23, thereby the length of the U-shaped ring road 24 can be short...

Embodiment 3

[0035] As shown in FIG. 3 , on the basis of the structure of Embodiment 1 and Embodiment 2, in order to reduce the U-turn distance of vehicles on the crossed road 3 , U-turn isolation belts 26 are respectively arranged on the left and right connecting platforms 23 . The U-turn isolation belt 26 divides the connecting platform 23 into a straight transition lane 27 and a U-turn lane 28 between the upper U-shaped ring road 24 and the lower U-shaped ring road 24, which satisfies the requirements of the upper U-shaped ring road 24 and the lower U-shaped ring road. Going straight between 24 makes the vehicle that needs to turn around on the crossed road 3 drive on the connecting platform 23 from the entrance driveway, and then turn around and drive into the exit driveway through the turnaround driveway 28, reducing the detour on the U-shaped ring road 24.

[0036] If the topographical conditions permit or the needs of traffic development, as shown in Figure 3, an underpass tunnel 6 c...

Abstract

This invention discloses a single layer overhead full interchange flyover, which is particularly suitable for urban highway and highway. Crossroads according to the invention has contact structure and takes up little ground, and achieves full interchange. The flyover comprises a main road and an intersected road , a 'U' shape circle road is disposed respectively at a predetermined level above both ends of the main road , an inner radius road and an outer radius road are disposed at the exit of each 'U' shape circle road, a common ramp is located between said inner and outer radius roads, the common ramp is joined with an exit driveway of the intersected road via the outer radius road; and an enter driveway of the intersected road is joined with an exit driveway of the main road via the inner radius road.

Description

technical field [0001] The invention relates to an overpass, in particular to an interchange overpass suitable for urban roads and expressways. Background technique [0002] In order to solve the unimpeded traffic at intersections on urban roads, various types of interchange schemes have been adopted at home and abroad, but in order to achieve the branch of motor vehicles and non-motor vehicles, and the transfer of vehicles in all directions without conflict and interference, it is necessary to build three floors accordingly Above the overpass road. The excessively high bridges and long ramps of such overpasses bring many disadvantages to the driving of motor vehicles, and occupy a large area. Especially in urban areas, they face many demolition and relocation difficulties, high compensation funds, and difficult operation and implementation. However, if the overhead turntable overpass is adopted, because the turning vehicles and the circular vehicles are constantly intertwi...
