Interchange type roundabout overpass
The invention belongs to the technical field of overpasses, and particularly relates to an interchange type roundabout overpass which comprises an upper-layer two-way straight lane and a lower-layer two-way straight lane, the upper-layer two-way straight lane comprises two upper-layer auxiliary bridges and two upper-layer descending left-turn auxiliary lanes, and the two upper-layer auxiliary bridges are communicated with the two sides of the upper-layer two-way straight lane respectively. The two upper-layer descending left-turn auxiliary lanes are respectively communicated with the two upper-layer auxiliary bridges and the two lower-layer auxiliary lanes; the lower-layer two-way straight lane comprises two lower-layer auxiliary lanes and two lower-layer ascending left-turn auxiliary lanes, and the lower-layer ascending left-turn auxiliary lanes are communicated with the inner sides of the two lower-layer auxiliary lanes and the inner sides of the two upper-layer auxiliary bridges respectively. The structure is simple, vehicles can turn left, turn right and turn around through the upper-layer descending right-turn auxiliary lane, the lower-layer ascending right-turn auxiliary lane, the upper-layer auxiliary bridge, the upper-layer descending left-turn auxiliary lane, the lower-layer ascending left-turn auxiliary lane and the lower-layer auxiliary lane, and when traffic accidents happen, the opposite lane is borrowed through the protective fences, so that the problem of vehicle passing is solved.
本发明属于立交桥技术领域，尤其是一种互通式环岛立交桥，包括上层双向直行车道和下层双向直行车道，所述上层双向直行车道包括两个上层附桥和两个上层下行左转辅道，两个所述上层附桥分别与上层双向直行车道的两侧相连通，两个所述上层下行左转辅道分别与两个上层附桥、两个下层辅道相连通；所述下层双向直行车道包括两个下层辅道和两个下层上行左转辅道，所述的下层上行左转辅道分别与两个下层辅道、两个上层附桥的内侧相连通。本发明结构简单，车辆通过上层下行右转辅道、下层上行右转辅道、上层附桥、上层下行左转辅道、下层上行左转辅道和下层辅道，完成左转、右转和调头，并在车祸发生时，通过防护栏借用对向车道，解决车辆通行问题。
