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 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, according to the existing left-turn---go straight---right-turn road division standard driving, it is too late to see the straight line---left turn---right turn road division standard after approaching the overpass bridge of this invention changing lanes, causing congestion and accidents
In a word, the road division specification of going straight --- turning left --- turning right from the inside of the ring to the outside of the ring required by the overpass is different from the existing road division specification of turning left --- going straight --- turning right, so that the overpass It cannot be applied on roads with existing left-turn---go straight---right-turn road division regulations

Embodiment 1

[0078] Embodiment 1. Four "L"-shaped single bridges turning counterclockwise that are suitable for the right-hand system are completely unblocked at the crossroads. Combined structure

[0079] Such as figure 1 , 6 , define an annular layer 1 on the surface of the subgrade at the intersection, and there are four lane-changing parts 2 on the annular layer 1 on the surface of the subgrade. One end of the ring inner edge 3 inside 2 is the entry point 4, and one end of the ring outer edge 5 in each lane change part 2 is the exit point 6; between the entry point 4 and the exit point 6 The area of ​​the annular layer 1 on the surface of the subgrade is the lane change part 2, with the center of the annular layer 1 on the subgrade surface as the center, the positions of the entering inner ring point 4 and the outer ring point 6 of the same lane changing part 2 are at the center angle 0 °--90° included angle within the corresponding arc;

[0080] It also includes four "L"-shaped sin...

Embodiment 2

[0103] Embodiment 2. The four "L" shaped tunnels that turn counterclockwise and are suitable for the right-hand system are completely unblocked at the intersection. Combined structure

[0104] Such as image 3 The difference between the unblocked combined structure of this embodiment and Embodiment 1 is that this embodiment uses four "L" shaped tunnels that turn in the same direction instead of the four "L" shaped single bridges that turn in the same direction in Embodiment 1. The ring-passing parts 7-2 of the four "L" shaped tunnels turning in the same direction pass through the annular layer 1 of the subgrade surface from below the ground. Other structures, lane divisions, left-turn and straight driving routes are all the same as in embodiment 1.

Embodiment 3

[0105] Embodiment 3. Two "U"-shaped single bridges that turn counterclockwise and two "U"-shaped tunnels that turn counterclockwise are suitable for the right-hand system. The inner part 7-1 of the ring is longer and the slope is smaller. The combined structure of the fully unobstructed intersection at the intersection

[0106] Such as Figure 4 , the difference between the unblocked combined structure of this embodiment and Embodiment 1 is: two "U" shaped single bridges turning in the same direction and two "U" shaped tunnels turning in the same direction, instead of the four "L" in Embodiment 1 "Single bridge that turns in the same direction.

[0107] In this embodiment, two ground branches of one group of straight lanes at the intersection are respectively connected to a single bridge with a "U" shape turning in the same direction, that is, two single bridges with a "U" shape turning in the same direction are respectively at the opposite side of the intersection. surface;...

Abstract

The invention relates to a smooth combination structure of four single bridges or tunnels turning in the same direction at a crossroad and belongs to the traffic building facility combination structure with totally smooth direct movement and big turning at the crossroad. A ring layer on the surface of a subgrade is provided with four lane changing positions and 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; one end of each single bridge or tunnel turning in the same direction is positioned outside a ring of the ring layer on the surface of the subgrade, while the other end thereof is connected with an inlet ring point of the ring layer on the surface of the subgrade; and the parts inside the rings of the four single bridges or tunnels turning in the same direction have the same turning direction. The smooth combination structure of the invention has the advantages that only four single bridges or tunnels turning in the same direction are constructed; and compared with other overpasses, the smooth combination structure uses fewest building facilities and lowest construction cost, occupies the smallest ground and space of the crossroad and realizes totally smooth direct movement and big turning without cross road occupation at the crossroad.

Description

technical field [0001] The invention belongs to the traffic construction facilities for going straight and making a big turn (left turn for right-hand system, right-turn for left-travel system) at the crossroads of main roads, in particular to use four single bridges or tunnels turning in the same direction to realize going straight and making a big turn The unimpeded combination structure of completely unimpeded traffic building facilities. 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, n...
