Description

A kind of overpass intersection scheme

Technical field

The invention belongs to transport development field, more particularly, to a kind of overpass intersection scheme.

Background technology

Overpass occupies critically important status in urban transportation, but overpass road has two very big defects：One, directly the vehicle of each intersection can not be carried out point, confluxed, the ring road up and down of overpass is set by region, in region by overpass across other road vehicles be concentrated to upper and lower overpass together, then many vehicles will detour many roads, and making the flow of surface road increases；Second, the position that overpass sets upper and lower ring road is usually provided at some intersection, and this intersection is typically all level-crossing, and vehicle is concentrated through increasing the intersection flow, most easily causes congestion.

The content of the invention

The present invention is intended to provide a kind of overpass can be all by across the upper and lower bridge in the crossing of road, and the floor at these crossings is intersected the scheme for being all transformed into crossings on different level, the program is on the basis of former overpass road, earth clearance is not again needed, as long as using double-decker bridge across the section of road in overpass, you can reach the purpose of upper and lower overpass and intersection grade separation.

Above technical problem is solved by following technical proposal：A kind of overpass intersection scheme is made up of overpass, two viaducts and two surface road intersections, and described overpass and viaduct builds up a dual deck bridge.It is characterized in that：Overpass is all completed by viaduct up and down.

Preferably, a kind of viaduct of described overpass intersection scheme is made up of approach viaduct, overbridge and ground access bridge.It is characterized in that：The vehicle of overpass walks approach viaduct and completes lower bridge to overbridge, ground access bridge to ground；Conversely, the vehicle on ground walks ground access bridge to overbridge, then walked on approach viaduct to overpass from overbridge.

Preferably, a kind of two viaducts of described overpass intersection scheme are frame thirty years of age of mirror image on two intersections being connected respectively, it is characterised in that：The vehicle of overpass can from it is overhead by under the first crossing overpass to ground, then from ground by the second crossing overpass to overhead.

Present invention tool has the advantage that：1st, original overpass road cross-line section is transformed, it is not necessary to newly-increased land used, is not required to policy treatment, substantially infrastructure construction is not needed, investment also less, after transformation just overpass and every intersecting road can organically connected, and realizes the full crossings on different level of intersection.2nd, can short distance set up overpass, two intersections can just set up most short one section of overpass unit, be incremented by with the multiple of unit.

Specific embodiment

The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings：

Referring to Fig. 1,2, overpass 1 at the intersection 3 on set up two viaducts 2 across the section of preceding intersecting roads 33 and rear intersecting roads 34, and overpass 1 builds up dual deck bridge, and upper strata is overpass 1, and lower floor is viaduct 2.The viaduct 2 of preceding intersection 31 connects overbridge 21 by access bridge 23 before approach viaduct 22, ground, and access bridge 24 is constituted after ground plane again；The viaduct 2 of intersection 32 connects access bridge 23 before overbridge 21 connects approach viaduct 22, ground again and constitutes by access bridge behind ground 24 afterwards.

Overpass intersection scheme sets overpass road as east-west, and it is south-north direction to intersect across road, and vehicle driving trace is as follows：

First, the north orientation of intersecting roads 33 is travelled the west vehicle of overpass 1 forward：From under approach viaduct 22, access bridge 25 arrives overpass surface road 11 after walking overbridge 21, ground, and then left-hand rotation u-turn is walked ground right-turn lane and northwards travelled into preceding intersecting roads 33.

2nd, the south orientation of intersecting roads 33 is travelled the west vehicle of overpass 1 forward, there is two schemes：First scheme：Access bridge 24 arrives overpass surface road 11 after walking approach viaduct 22, overbridge 21, ground, then left-hand rotation u-turn walks behind ground that access bridge 23 returns to overpass surface road 11 before access bridge 24, overbridge 21, ground, then u-turn of turning left is walked ground right-turn lane and travelled southwards into preceding intersecting roads 33；Alternative plan：Access bridge 24 to overpass surface road 11, walk ground right-turn lane and northwards travel stretch into preceding intersecting roads 33, then u-turn of turning left enters preceding intersecting roads 33 and travels southwards by then left-hand rotation u-turn after walking approach viaduct 22, overbridge 21, ground.

3rd, the south orientation of intersecting roads 34 is travelled the west vehicle of overpass 1 backward, and to overpass surface road 11, ground right-turn lane of then keeping straight on enters the traveling southwards of rear intersecting roads 34 to access bridge 24 after walking approach viaduct 22, overbridge 21, ground.

4th, the north orientation of intersecting roads 34 is travelled the west vehicle of overpass 1 backward, there is two schemes：First scheme：Access bridge 24 arrives overpass surface road 11 after walking approach viaduct 22, overbridge 21, ground, straight trip is gone further behind ground before access bridge 24, overbridge 21, ground access bridge 23 to overpass surface road 11, and then left-hand rotation u-turn is walked ground right-turn lane and northwards travelled into rear intersecting roads 34；Alternative plan：Access bridge 24 to overpass surface road 11, walk right-turn lane and enter the traveling stretch southwards of rear intersecting roads 34, then u-turn of turning left northwards is travelled into rear intersecting roads 34 by straight trip after walking approach viaduct 22, overbridge 21, ground.

5th, the north vehicle of preceding intersecting roads 33 has two schemes to the west of overpass 1 to traveling：First scheme：Walk right-turn lane into overpass surface road 11, turn left before u-turn upper ground surface after access bridge 23, overbridge 21, ground access bridge 24 to overpass surface road 11, then u-turn of turning left is walked access bridge 24 behind ground, overbridge 21, approach viaduct 22 and westwards travelled to overpass 1；Alternative plan：Kept straight on southwards crossing rear left modulation head along preceding intersecting roads 33, walked right-turn lane into overpass surface road 11, then u-turn of turning left is walked access bridge 24 behind ground, overbridge 21, approach viaduct 22 and is westwards travelled to overpass 1.

6th, the north vehicle of preceding intersecting roads 33 is travelled to the east orientation of overpass 1, there is two schemes：First scheme：Walk the right-turn lane of preceding intersecting roads 33 into overpass surface road 11, access bridge 24 returns to overpass surface road 11 after access bridge 23, overbridge 21, ground before left-hand rotation u-turn upper ground surface, and access bridge 24, overbridge 21, approach viaduct 22 are travelled eastwards to overpass 1 after upper ground surface again of keeping straight on；Alternative plan：Kept straight on southwards crossing rear left modulation head along preceding intersecting roads 33, walked right-turn lane into overpass surface road 11, access bridge 24, overbridge 21, upper approach viaduct 23 were travelled eastwards to overpass 1 after straight trip upper ground surface.

7th, the vehicle in the south of preceding intersecting roads 33 is travelled to the east orientation of overpass 1, walks right-turn lane into overpass surface road 11, and access bridge 24, overbridge 21, approach viaduct 22 are travelled eastwards to overpass 1 after straight trip upper ground surface；

8th, the vehicle in the south of preceding intersecting roads 33 walks right-turn lane into overpass surface road 11 to the west of overpass 1 to traveling, and access bridge 24, overbridge 21, approach viaduct 22 are westwards travelled to overpass 1 after the u-turn upper ground surface that turns left.
