Embodiment Construction

[0011] figure 1 Among them, between the outer side of the bow-shaped overpass 3 of the longitudinal road and the inner side of the vertical left-turn downhill ramp 15 of the car on the opposite side, a longitudinal left-turn ramp 5 is set, parallel to the overpass, and after crossing the sky over the transverse road surface 1, that is Parallel to the ground until it is above the downhill end of the overpass bridge, then turn left and cross the longitudinal road surface 4 and over the vertical left-turn uphill ramp 16 outside the other end of the overpass bridge, then turn down along its outer side to the exit of the longitudinal left-turn ramp and The intersection 13 of the horizontal road surface merges into the first lane of the horizontal road surface to realize a longitudinal left turn; after the first lane of the horizontal road surface passes through the vertical left-turn aerial ramp 11, it turns right along its inner side until it meets the turning point of the longitud...

Abstract

The invention relates to the technical field of flyovers and is characterized in that: a longitudinal left-turn ramp is arranged between the outer side of an arched overpass bridge of a longitudinal road and the inner side of a longitudinal left-turn downgrade ramp for an opposite coming vehicle; the longitudinal left-turn ramp and the overpass bridge are abreast upward; after bridging over a transverse road surface, the longitudinal left-turn ramp is parallel to the ground between the airspace of the transverse road surface and the airspace of the bridge head at the downgrade end of the overpass bridge; then the longitudinal left-turn ramp turns left to bridge over a longitudinal road surface and a longitudinal left-turn upgrade ramp on the outer side of the other end of the overpass ridge, and turns around and moves downwards to get into a first lane of the transverse road surface; after the first lane of the transverse road surface underneath passes through a longitudinal left-turn air ramp, namely the first lane turns right and moves upwards along the inner side of the first lane until the first lane is connected to the corner of the longitudinal left-turn ramp, the first lane turns left on the inner side and bridges over the longitudinal road surface, then turns left again at a position close to the inner side of the longitudinal left-turn upgrade ramp and moves forwards in a state of being parallel to the ground, and gets into the overpass bridge at the highest part of the arched overpass bridge; furthermore, intersection platforms are arranged at intersections between the longitudinal and transverse left-turn upgrade ramps and the middle part of the left-turn downgrade ramp for the opposite coming vehicle, so that longitudinal and transverse right turns can be realized.

Description

technical field [0001] The invention relates to the technical field of overpass bridges. Background technique [0002] At present, the existing all-interchange overpass has many layers and occupies a large area, so it cannot be erected in the urban area. Even if the one-line all-interchange single-layer overpass of the patent 2005100221946 can overcome the above shortcomings, the turning radius of the U-shaped ramp that turns left is relatively small , Turning speed is slow, not ideal. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings, the present invention provides a single-layer fully-enclosed fully-interchangeable overpass in urban areas, which is innovatively improved on the basis of patent 2005100221946, and can achieve the purpose of increasing the turning radius without increasing the occupied area. . [0004] The technical solution of the present invention to solve the technical problem is: a single-layer full...
