Problems solved by technology

Its disadvantages: First, there are two kinds of driving regulations on a cross road. Drivers must recognize the traffic signs painted on the ground every time they cross the cross road.
The second is that the road division specification of going straight from the inside of the ring to the outside of the ring --- turn left --- turn right is different from the existing road division specification of turning left --- go straight --- turn right, which makes it easy for drivers to drive away from the intersection. Before the mouth, drive according to the existing left-turn---go straight---right-turn road division standard driving, and just see the straight line---left turn---right turn road division standard when approaching the overpass single bridge of the invention It is too late to change lanes, causing congestion and accidents
In a word, the road division specification of going straight --- turn left --- turn right from the inside of the ring to the outside of the ring required by the interchange single bridge is different from the existing road division specification of turn left --- go straight --- turn right. This interchange single bridge cannot be applied on the road with the existing left turn---go straight---right turn road division specification

Embodiment 1

[0038] Embodiment 1, the fully unimpeded combined structure of four straight-going single bridges and four left-turning single bridges at the intersection

[0039] Such as figure 1 , 3 , the intersection has four curved straight single bridges 1 and four large curved left turn single bridges 2, the crossroads have four ground branches, and the straight lanes of each ground branch into the intersection are connected with an arc The curved straight single bridge 1 is connected, and the left-turn lane is connected with a large curved left-turn single bridge 2.

[0040] Two kinds of single bridge structures: the two ends of the curved straight single bridge 1 are respectively connected with the straight ground branch roads at the opposite ends of the crossroads, and the arc curved straight single bridge 1 has a right side branch in the middle of the branch. Outwardly convex right convex arc bend section 4; the two ends of the large arc bend left turn single bridge 2 are respecti...

Embodiment 2

[0045] Embodiment 2. Four groups of straight-going single bridges and left-turning single bridges at the intersection are connected in the same group of parallel sections to form a fully unimpeded combined structure on a smooth surface

[0046] A ground branch road enters an arc-shaped straight-going single bridge at the crossroads 1 on the outside of the arc-shaped bend and a left-turn single bridge 2 on the inside of the arc-shaped bend to form a combined single bridge, four groups of straight-on single bridges and left For the four combined single bridges formed by the turning single bridges, the parallel sections 8 of the same group of each combined bridge are connected to form a smooth surface, and the arcs of the four parallel sections 8 of the same group are all the same. Other structures are the same as in Embodiment 1.

Embodiment 3

[0047] Embodiment 3. The eight single bridges at the crossroads are all connected to form a smooth surface at the same detour position, and synthesized into a fully unimpeded combined structure of a fully enclosed ring bridge.

[0048] Such as Figure 4 , the same group of parallel sections 8 of a combined single bridge is connected to form a smooth surface, and the same group of parallel sections 8 of different combined single bridges at the same position are also connected to form a smooth surface, and the large arc bend of the previous combined single bridge is turned left The left-turn large arc bend section 5 of the single bridge 2 is connected with the right convex arc bend section 4 of the rear arc bend straight single bridge 1 to form a smooth surface, and becomes any single bridge in the same detour position, all according to the original internal and external Arranged positions are connected to form a smooth surface, combined into one bridge deck, then the detour sec...

Abstract

The invention relates to a completely unblocked composite structure consisting of eight single bridges at a right-hand intersection and belongs to a composite structure by which eight independent non-crossed single-layer arch bridges at an intersection can realize completely unblocked straight movement and left-hand bend. The composite structure comprises four single bridges for straight movement and four single bridges for left-hand bend, wherein a middle segment of each curve-bend straight-movement single bridge is a rightwards-protruded arch bend segment which is protruded rightwards and outwards; a middle segment of each large curve-bend left-hand bend single bridge is a left-hand bend large curve-bend segment which is protruded rightward and then protruded oppositely; a composite single bridge is formed by arranging one curve-bend straight-movement single bridge outside the curve bend of one large curve-bend left-hand bend single bridge; the number of the composite single bridges is four; and according to a counterclockwise sequence, the front composite single bridge is arranged outside the arch shape of the back composite single bridge. Compared with the conventional two-layer and three-layer overpasses at the intersection, the composite structure has the advantages of realizing completely unblocked straight movement and left-hand bend without crossed road occupation by using four single bridges for the straight movement and four single bridges for the left-hand bend, reducing the cost of bridge construction and reducing the height of overpasses.

Description

technical field [0001] The invention belongs to the design of a traffic bridge at a main road crossing, in particular to a combined structure in which eight independent single-layer arch bridges that do not intersect with each other can realize straight travel and left turns completely unimpeded. Background technique [0002] At present, the traffic at level crossings of international and domestic urban arterial roads is very crowded and often blocked, which is a common problem in major cities all over the world. The reason is that two roads intersect at a level. At the intersection, the two roads overlap and become one road. Vehicles on the two roads can only share one road at the node, and half of the road resources are lost. It will affect the driving speed and traffic volume. Coupled with the mixed traffic of pedestrians, non-motor vehicles and motor vehicles, congestion is an inevitable result. In order to solve this difficult problem, people have thought of widening ...
