Problems solved by technology

People thought of tunnels again, but in the current design scheme of Liwen Tunnel, the minimum diameter of the tunnel that can make the straight-going tunnel and the right-turning tunnel at the crossroads without crossing and occupying conflicts is less than 120 meters. No crossroads with six lanes can be built, so that the traffic jams at the crossroads in the old city are very serious, and some crossroads often have traffic paralysis

Embodiment 1

[0063] Embodiment 1, the crossroads of the left-hand traffic system, the combined tunnel of the left-hand system long and short shape four independent "Y"-shaped bifurcated tunnels formed by two double-embedded grouping tunnels.

[0064] Such as figure 1 , 2 , 3,

[0065] 1. Cross-shaped main structure: There are four ground branch roads at the intersection, two opposite ground branch roads form a cross-shaped structure with the other two opposite ground branch roads, and a branch in the same direction is built under the four ground branch roads "Y" shaped fork tunnel 1. Two same-direction bifurcated "Y"-shaped fork tunnels 1 opposite to the bifurcation mouth form a packet tunnel, and four same-direction bifurcated "Y"-shaped fork tunnels 1 respectively form two packet tunnels, and the two packet tunnels are divided into double Embedded packet tunnel and single embedded packet tunnel. The four common entry tunnel grounding ends 4 of the four same-direction bifurcating "Y"-...

Embodiment 2

[0077] Embodiment 2, the intersection of left-hand traffic system, the single-track section of the right-curved tunnel is a combination tunnel of four independent "Y"-shaped bifurcated tunnels with long and short left-hand system in concave arc shape.

[0078] It includes the entire structure of Embodiment 1, and the straight tunnel ground end 5 of the dual embedded packet tunnel is at the ground position above the bifurcation section 7 of the "Y"-shaped fork tunnel 1 that is close to the opposite same direction bifurcation. The right-curved tunnel one-way section 13 is an arc structure concaved toward the central area of ​​the three-dimensional cross-shaped structure of two groups of straight tunnel one-way sections 8 of the two grouped tunnels. Taking the center point of the three-dimensional cross-shaped structure of the two groups of straight tunnel single-row sections 8 of the two grouping tunnels as the center, the relative shortest distance between the two arc-shaped rig...

Abstract

The invention discloses a combined tunnel of four independent left-side-driving long and short Y-shaped bifurcate tunnels, which is a combined structure capable of making a crossroad smooth and combined by four independent bifurcate tunnels. Each bifurcate tunnel has one straight tunnel and one right-turning tunnel, wherein the right-turning tunnel is bifurcate with the straight tunnel at the right-turning side, thereby a Y-shaped bifurcate tunnel is formed, and four bifurcate tunnels form four equidirectionally-bifurcate Y-shaped tunnels; two equidirectionally-bifurcate Y-shaped tunnels form a grouping tunnel, two groups of straight tunnel one-way sections of two grouping tunnels are of a stereo cross-shaped structure. The combined tunnel has the advantages that the disaster degree of the local geological change to the entire combined tunnel is reduced, the right-turning tunnel can be used as a right-turning and left-turning shared tunnel, a wider ground can be used as a combined driveway zone to avoid the traffic jam, no redundant bypass exists during the direct right-turning, and the small crossroad having bidirectional six lanes is made to be interconnected.

Description

technical field [0001] The present invention belongs to the tunnel that makes motor vehicle traffic unimpeded at intersections, especially four independent bifurcated tunnels are combined to make straight motor vehicles (above abbreviated: straight vehicles) and right-turning motor vehicles (above abbreviated: right-hand vehicles) at intersections Turning car) a smooth combination structure of multiple tunnels without cross-occupancy conflicts. 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. Under the intersection, the two roads overlap and become one road. Motor vehicles under the two roads can only share one road under the node, and half of the road resources are lost. Coupled with the mixed traffic of pedestrians, non-motor vehicles and motor vehicles...
