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. In front of the mouth, drive according to the existing left turn---go straight---right turn road division standard, and it is too late to see the straight line---left turn---right turn road division standard after approaching the tunnel of the invention changing lanes, causing congestion and accidents
In a word, the road division specification of the tunnel from inside to outside of the ring—go straight—turn left—turn right is different from the existing road division specification of turn left—go straight—turn right, which makes the tunnel It cannot be applied on roads with existing left-turn---go straight---right-turn road division regulations

Embodiment 1

[0061] Embodiment 1, a tunnel structure in which vehicles turn left and go straight at an intersection where vehicles travel on the right

[0062] like figure 1 , four lane-changing parts 2 are arranged on a ring-shaped tunnel 1, each lane-changing part 2 is respectively on the left side of a ground branch road at a crossroad, and one end of the ring inner edge 3 in each lane-changing part 2 is for entering Ring point 4, one end of the ring outer edge 5 in each lane change part 2 is the outer ring point 6; the area of ​​the ring tunnel 1 between the inner ring point 4 and the outer ring point 6 is the lane change part 2, Taking the center of the circular tunnel 1 as the center of the circle, the positions of the entering inner loop point 4 and the exiting outer loop point 6 of the same lane change part 2 are within the arc corresponding to the included angle of 0°--90° at the center of the circle;

Abstract

The invention relates to a single-layer ring-shaped tunnel for direct movement and big turning at a crossroad and belongs to a structure design of the single-layer ring-shaped tunnel which can realize totally smooth direct movement and big turning at the crossroad. The ring-shaped tunnel is provided with four lane changing positions. The radian of each lane changing position is in the range of the radian corresponding to 0 to 90 degrees of an inclined angle of a center angle; an inlet ring point of one lane changing position is communicated with an inner ring single-rampway tunnel, while an outlet ring point thereof is communicated with one outer ring single-rampway tunnel; and all the inner ring single-rampway tunnels have the same turning direction. The single-layer ring-shaped tunnel has the advantages of only using one single-layer ring-shaped tunnel and four groups of inner ring single-rampway tunnels and outer ring single-rampway tunnels, being capable of realizing direct movement and big turning at the correct lanes to make vehicles run smoothly totally, using fewest bridge building facilities and lowest bridge construction cost, occupying the smallest ground and space of the crossroad and realizing totally smooth crossroad without cross road occupation.

Description

technical field [0001] The present invention belongs to the tunnel design for going straight and making big turns at intersections of arterial roads, especially can realize going straight and making big turns (left-turning cars traveling on the right and cars turning right on the left) with a single-layer annular tunnel. Smooth structural design. 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...
