Description
The invention belongs to the highway bridge design field, particularly crossroad, city, T-shaped road junction do not have the structure design of the overpass bridge that reverses ring road, no at grade intersection point.
Along with the human society modernization process, various vehicles are increasing in the city, and traffic congestion, obstruction, traffic accident become modern metropolitan cities one big drawback again and again.For transport solution stops up, various forms of overpass bridges appear at each main crossing intersection part of city in succession, have realized that the solid of the motor vehicle of road intersection is separated, and become a big characteristic of modern metropolitan cities.But existing various overpass bridge also has following weak point, and one, left lateral road all adopt and reverse ring road and solve left lateral and the craspedodrome problem that crosses, so the overpass bridge floor space is big, and the left lateral car car that turns around far by intersection need detour hundreds of rice even several kilometers more.Its two, intersect and the problem that interweaves of bicycle and motor vehicle still do not have fine solution, cause vehicle ' not smooth, even traffic accident takes place.Its three because the overpass bridge floor space is big, makes some intersection can not build overpass bridge, and cause bottleneck effect, cause the city to ship that the traffic capacity is whole to descend.
The objective of the invention is to for overcoming the weak point of existing overpass bridge, proposing a kind of nothing reverses, scissors-type directional formula overpass bridge structure, not only realize motor vehicle do not have cross, orientation is travelled, route is short prompt, service ability is big, and realize separating of motor vehicle and bicycle, pedestrian, and floor space is little, engineering simple, cost is lower, can be widely used in crossroad, the T-shaped road junction of all size, help to improve the service ability of city integral body, reduce traffic accident.
The present invention proposes a kind of crossroad non-return scissors-type directional overpass, double-deck major trunk roads by four same structures by the intersection are formed, it is characterized in that, the lower floor that every major trunk roads are divided into cross towards the crossing direct motion road, upper strata at center and the center that crosses the dorsad road that drives in the wrong direction, separate after said direct motion road draws on gradually and be left lateral, keep straight on, three orientated pathway of right lateral are also curved left, Xiang Zhiqian, curved to the right drawing down gradually is connected to its left side, before, the retrograde road at three crossings of right, draw from the craspedodrome at its left crossing under said every left lateral orientated pathway, pass under the left lateral orientated pathway, the craspedodrome orientated pathway passes under the left lateral orientated pathway of its junction ahead, said retrograde road is by its left side, before, the right lateral at three crossings of right, keep straight on, draw under three direct motion orientated pathway of left lateral and merge, said relative direction two craspedodrome orientated pathway become in the center that crosses up and down to intert and mistake with two craspedodrome orientated pathway of other two directions.
A layer nonmotorized vehicle lane can be set in above-mentioned each outside, arterial highway.

Only need not to reverse to detour with left turning vehicle and be example, compare with general overpass bridge, the bridge can be saved 61.32 ten thousand liters in gasoline every year, closes about 1,400,000 yuan of RMB.Detour 1000 meters in the left turning vehicle decreased average, or per hour the bicycle road traffic capacity is 1000, then the car of turning left is per hour 2000, and calculated by 12 hours every day, reduce left turning vehicle every day and detour 2.4 ten thousand kilometers, save 1680 liters of oil masses (oil consumption be 7 liters/100Km).1 year is 61.32 ten thousand liters of fuel-economizings, closes 1,400,000 yuan of RMB (oil price is 2.3 yuan/liter).And the tune car reduces and to detour greatlyyer more than two times than left turning vehicle, had both made the tune car big not as left turning vehicle quantity, but considerable economic is arranged equally.
(2) occupation of land is little, and cost is low.
This form overpass bridge is compared with the complete formula clover blade profile overpass bridge of said function, owing to reduced by four loop ramps, floor space can reduce 3/4～5/6, one high and one low formula is all adopted in each track simultaneously, just can save 1/3 of overhead pontic engineering material consumption, compare with general directional interchange bridge, construction costs can greatly reduce.
(3) reduce environment pollution.
Guarantee that the vehicle by the intersection advances freely because this form overpass bridge intersects, and reduced the environment pollution that the vehicle exhaust because of vehicle deceleration, oil mass that brake, starting consumed and generation causes.
(4) reduce because of the economic loss that traffic accident produced and the input of traffic signals facility.
Because motor vehicle, bicycle use Correct Lane, avoided the generation of crossing traffic accident, the considerable economic and social benefit that consequent direct economic loss and indirect economic loss bring for the country and people can be saved the input that signal lamp control system is installed simultaneously.
