Rotor overpass

Abstract

The invention relates to the technical field of road construction design, in particular to a rotor overpass. The rotor overpass comprises a bottom course, a middle course and a top course and is characterized in that the bottom course comprises a first bottom course and a second bottom course; the first bottom course comprises a sidewalk and a non-motor vehicle lane in the bottom course; the second bottom course is a deck, which is straight-going to communicate the east direction with the west direction and is positioned above the first bottom course; the second bottom course comprises a thirdleft-turn lane, a fourth left-turn lane, a third straight lane and a fourth straight lane; the top course is a deck which is straight-going to communicate the north direction with the south direction; the top course comprises a first straight lane, which is in communication with a third meeting lane, and a second straight lane, which is in communication with a fourth meeting lane; and the middlecourse is a turning bypass deck which communicates the second bottom course with the top course. The rotor overpass has the advantages that the floor space is small, the turning radius is large, the path is long, the lane is reasonably increased and reduced and the traffic operation is smooth.

Description

technical field [0001] The invention relates to the technical field of road building design, in particular to a rotor overpass. Background technique [0002] 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 go straight, turn left and turn right at the same time; The overpass that can realize these functions is usually designed with a circular line. When going straight, it needs to go around a semicircle line to drive to the straight lane, or when turning left, it needs to go around an arc line to drive to the destination lane, which often forms a traffic jam. In the situation of entrances and exits, it is necessary to take a long detour when making a U-turn; it makes the intersection very congested, causing great distress to the driver, and causing a great negative i...
