Abstract

A kind of multi-functional left-turn directional interchange overpass, it includes grillage foundation road surface, there is the road of four corners of the world four direction, vertical and horizontal viaduct is had in crossing intersection part erection, wherein horizontal viaduct is on longitudinal viaduct, form two-layer Viaduct Structure, it is characterized in that: be provided with right-hand bend arch bridge on the right of every bar road, described vertical and horizontal viaduct is respectively provided with four tracks, between track, jube is installed between two, and the left turn lane that on every viaduct, middle two tracks are reverse each other, gap bridge one end that two left turn lanes are positioned at viaduct has set up 90 ° of left-hand bend downward bridges respectively, ground level road under connecting bridge, and on the ground, below of longitudinal viaduct, the tune track of People's Bank of China passageway, nonmotorized vehicle lane and four direction is arranged with by line, the invention solves existing overpass bridge can not directly turn left, construction cost is high, affects the problem such as traffic speed and order, and the crossroad being particularly suitable for highway is built.

Description

Multi-functional left-turn directional interchange overpass

Technical field

The present invention relates to traffic highway, especially a kind of multi-functional left-turn directional interchange overpass.

Background technology

In traffic highway, the crossroad place that amount of flow is larger, usually need to set up overpass bridge, existing overpass bridge form of structure is multiple, but does not have a kind ofly can directly to turn left, the left-hand bend of vehicle can only be realized by the right-hand bend road of 270 °, this bridge construction cost is high, and floor space is large, the land resources that waste is valuable, and have cross interleave road conditions, affect traffic speed and order and security.

Summary of the invention

Object of the present invention will solve existing overpass bridge exactly and can not directly turn left, and the above-mentioned series of problems brought provides a kind of multi-functional left-turn directional interchange overpass.

Concrete scheme of the present invention is: multi-functional left-turn directional interchange overpass, include grillage foundation road surface, there is the road of four corners of the world four direction, vertical and horizontal viaduct is had in crossing intersection part erection, wherein horizontal viaduct is on longitudinal viaduct, form two-layer Viaduct Structure, it is characterized in that: be provided with right-hand bend arch bridge on the right of every bar road, described horizontal viaduct is provided with four tracks, between track, jube is installed between two, the left turn lane that wherein, two tracks are reverse each other, gap bridge one end that two left turn lanes are positioned at viaduct has set up 90 ° of left-hand bend downward bridges respectively, ground level road under connecting bridge, longitudinal viaduct is provided with four tracks, the left turn lane that wherein, two tracks are reverse each other, gap bridge one end that two left turn lanes are positioned at viaduct has set up 90 ° of left-hand bend downward bridges respectively, wherein every bar left-turning pathways, all goes up a slope with the craspedodrome road gone in the same direction after by overpass bridge simultaneously and crosses over, and is arranged with the tune track of People's Bank of China passageway, nonmotorized vehicle lane and four direction by line on the ground, below of longitudinal viaduct.

In the present invention, the vehicle of four direction all can directly turn left, current easy, do not interweave mutually, have complete directed intercommunication, vehicle is in the process of traveling whole crossroad, its road voluntarily, easy, quick, safety, adds the traffic capacity of overpass bridge, ensure that vehicle travels in way and does not block up, improve passage rate, ensure that traffic safety.On the ground, below of longitudinal viaduct, be provided with sidewalk, nonmotorized vehicle lane, tune track simultaneously, greatly facilitate pedestrian and non motorized vehicle passageway, and motor vehicle tune.And construction cost of the present invention is low, and floor space is little, save valuable land resources.

Accompanying drawing explanation

Fig. 1 is perspective view of the present invention.

In figure: 1-north orientation road, 2-south orientation road, 3-east orientation road, 4-is western to road, 5-right-hand bend arch bridge, 6-90 ° of left-hand bend downward bridge, the horizontal viaduct of 7-, the longitudinal viaduct of 8-, 9-jube.

Detailed description of the invention

See Fig. 1, the present invention includes grillage foundation road surface, there is the road 1 of four corners of the world four direction, 2, 3, 4, vertical and horizontal viaduct 8 is had in crossing intersection part erection, 7, wherein horizontal viaduct 7 is on longitudinal viaduct 8, form two-layer Viaduct Structure, particularly: be provided with right-hand bend arch bridge 5 on the right of every bar road, described horizontal viaduct 7 is provided with four tracks, between two jube 9 is installed between track, the left turn lane that wherein, two tracks are reverse each other, gap bridge one end that two left turn lanes are positioned at viaduct has set up 90 ° of left-hand bend downward bridges 6 respectively, ground level road under connecting bridge, longitudinal viaduct 8 is provided with four tracks, the left turn lane that wherein, two tracks are reverse each other, gap bridge one end that two left turn lanes are positioned at viaduct has set up 90 ° of left-hand bend downward bridges 6 respectively, wherein every bar left-turning pathways, all goes up a slope with the craspedodrome road gone in the same direction after by overpass bridge simultaneously and crosses over, and is arranged with the tune track of People's Bank of China passageway, nonmotorized vehicle lane and four direction by line on the ground, below of longitudinal viaduct 8.

Claims

1. multi-functional left-turn directional interchange overpass, include grillage foundation road surface, there is the road of four corners of the world four direction, vertical and horizontal viaduct is had in crossing intersection part erection, wherein horizontal viaduct is on longitudinal viaduct, form two-layer Viaduct Structure, it is characterized in that: be provided with right-hand bend arch bridge on the right of every bar road, described horizontal viaduct is provided with four tracks, between track, jube is installed between two, the left turn lane that wherein, two tracks are reverse each other, gap bridge one end that two left turn lanes are positioned at viaduct has set up 90 ° of left-hand bend downward bridges respectively, ground level road under connecting bridge, longitudinal viaduct is provided with four tracks, the left turn lane that wherein, two tracks are reverse each other, gap bridge one end that two left turn lanes are positioned at viaduct has set up 90 ° of left-hand bend downward bridges respectively, wherein every bar left turn lane, all by crossing over side by side with the direct lane that goes in the same direction during overpass bridge, the then descending that turns left after upward slope enters ground level road, and is arranged with the tune track of People's Bank of China passageway, nonmotorized vehicle lane and four direction by line on the ground, below of longitudinal viaduct.
