Abstract

The invention relates to a non-interweaved ring flyover, comprising a track, multiple groups of left-handed ring-in ramps and ring-out ramps, wherein an entry where each group of the left-handed ring-in ramp enters the track is located outside of the track and an exit where the corresponding ring-out ramp leaves the track is located inside of the track. The left-handed ring-in ramp and the ring-out ramp of the ring flyover are respectively arranged on the outside and inside of the track, so that the ring-in and ring-out way is changed from the original external-in external-out way into an internal-in external-out or external-in internal-out way, i.e., the in-out on the same side is replaced with the in-out on different sides; and by changing the accessing way and accessing position of the left-handed ring-in ramp and the ring-out ramp, the interweaving of the track is eliminated, and the rounding angle of vehicles on the track is reduced.

Description

technical field

[0001] The invention belongs to the technical field of overpasses, in particular to a ring-shaped overpass without weaving. Background technique

[0002] Interchange (interchange for short) is an important traffic organization facility of modern urban road system. Ring interchanges are widely used in interchange construction because of their compact layout, less land occupation, and low cost. However, practice has proved that the existing ring interchanges are not suitable in many cases, such as the central area of ​​a megacity, the intersection with a large left-turn traffic volume, etc.

[0003] The roundabout is evolved from the roundabout, and the turning of vehicles in all directions is realized through the roundabout. According to the separation level of traffic flow, ring interchanges can be divided into two-layer, three-layer, four-layer and other forms. Taking the intersection as an example, the three-level roundabout (such as figure 1 Shown) is ...

Embodiment Construction

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] Please refer to image 3 and Figure 4 , the non-interweaving circular interchange of the present invention comprises a ring road 1, and multiple groups of left-turning ring-turning ramps 2 and ring-out ramps 3, each group of left-turning ring-turning ramps 2 entering the entrance of the ring road 1, and corresponding ring-out ramps 3 The exits from the ring road 1 are located on both sides of the ring road 1.

[0038] In the circular interchange of the present invention, the left-turning ring road 2 and the ring road 3 are placed on both sides of the ring...
