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

[0019] Such as figure 1 As shown, the overpass is set at the crossroads, and the crossroads are divided into four main line intersections: up, down, left, and right. Among them, the up and down directions are the main road 1 with a large traffic flow, and the left and right directions are the crossed roads 3. The overpasses are in four The intersection is at the same level as the arterial road surface and connected. 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...

Embodiment 2

[0031] 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 loop 24, carry out local modification on the structure of embodiment 1, as figure 2 As shown, the height of the circular arc section 25 of the U-shaped ring road 24 is higher than the height of the connecting platform 23, so that the upper and lower U-shaped ring roads 24 are combined to form a saddle shape 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 shortened. ...

Embodiment 3

[0034] like image 3 As shown, 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.

[0035] If the topographical conditions permit or the needs of traffic development, it can also be image 3 As shown, on the ...

Abstract

The invention discloses a single-layer overhead full-interchange overpass, which is particularly suitable for use on urban roads and expressways. The overpass bridge provided by the invention has a compact structure and occupies less land, and can realize full intercommunication. The technical scheme adopted in the present invention is: the single-layer overhead full-interchange overpass of the present invention includes the main line road and the crossed road, and a U-shaped ring road is respectively arranged above the horizontal height of both ends of the main line road, and the above-mentioned U-shaped ring road The exit section is provided with an inner half ring road and an outer half ring road, and a shared ramp is set between the inner half ring road and the outer half ring road; the shared ramp is connected with the exit lane of the road to be crossed through the outer half ring road; The entrance lane of the road is connected with the exit lane of the main road through the inner half ring road. The beneficial effect of the invention is that the transfer of vehicles in all directions can be skillfully realized without interference and conflict. The utility model also has obvious improvement on noise reduction and exhaust emission reduction of motor vehicles, and has low construction cost, is more suitable for environmental protection, and is beautiful.

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...
