Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] With reference to Fig. 1, the east-west main road 1 is the upper layer on the cross-orthogonal bridge, the north-south main road 2 is the lower layer on the cross-orthogonal bridge, and both main roads are two-way multi-lane. Between the east-west main road 1 and the north-south main road 2, there are four inner arc-shaped right-turn passages 3-6 between the two main roads (upper and lower floors) in the four directions where the cross-orthogonal bridge approaches the intersection , where: right-turn passages 3 and 5 are right-turn passages from north-south main road 2 (lower floor) to east-west main road 1 (upper floor); right-turn passages 4 and 6 are east-west main road 1 (upper floor) to The right-turn passage of north-south main road 2 (lower floor).

[0013] Each of the four extension directions of the two main roads of the cross-orthogonal brid...

Abstract

The invention relates to a rotating smooth type crossroad, comprising a cross right bridge. The cross right bridge is provided with four inner arc right hand bending channels; the four extending directions of the main artery on the cross right bridge are respectively provided with a left rotating channel which is an arc bending channel left rotating 360 degrees. The invention not only solves the vehicle smooth problem at the crossroad without red and green light control, but also has the advantages of simple structure, few layers, low height, short approaching bridge and investment saving, which is beneficial for popularizing and use.

Description

technical field [0001] The invention relates to a highway overpass, in particular to a turn-around unimpeded overpass. Background technique [0002] With the development of society, motor vehicles are constantly increasing, and the problem of smooth roads has attracted much attention, especially the problems of urban traffic congestion and traffic jams at intersections, which need to be solved urgently. For vehicle traffic at intersections, cross-orthogonal bridges and single-layer roundabout viaducts are generally used. Although these can improve the traffic conditions at intersections, they must be controlled by traffic lights, and the traffic efficiency is very low. A kind of all-direction direct intercommunication type overpass appeared afterwards, this kind of overpass can not be provided with traffic light, and vehicle can run directly, has solved the traffic problem of intersection better, but this kind of overpass has as many as four floors, the approach bridge is lo...
