Abstract
The present invention relates to an unblocked overpass built up near by long and narrow urbon-road intersection. It is mainly characterized by that the desribed bridge body is a stretch overpass built on the road bear by intersection, and along two sides of road the slopeways connected with the stretch overpass are respectively built up, so that said invention possesses the advantages of reasonable structure, convenient construction, small floor area, short construction period, low cost, anc can effectively eliminate traffic strangulation, etc.
Description
The present invention relates to a kind of overpass bridge facility of urban road, especially relate to a kind of prong place comparatively crowded or the suitable expanding location of nothing that is arranged on, can make middle-size and small-size motor vehicle go to the novel smooth overpass of any cross road unblockedly.
" if want rich, construct a road ", along with compatriots have the rapid raising of vehicle rate, the road prong of urban road, the especially old town phenomenon that blocks up often.The urban road prong is the throat of traffic, and each road vehicles, bicycle, pedestrian pool together, and owing to the existence of traffic lights, has blocked the smoothness of traffic, has reduced the traffic capacity of road, and it is over half that road has been reduced.In addition, vehicle periodically brakes, starts in the intersection, and also all very big for the consumption of fuel, part and tire, this influences expanding economy day by day.To this, people had once done various effort, and had proposed all solutions.For example, the someone has applied for the patent of invention (patent No. 94105966.9) of " 4/4 (4/3) lane double layer crossless stereo bridge on land " by name.It mainly is applicable to 4/4 (4/3) track, it is a kind of double layer crossless stereo bridge on land, mainly solve the graded crossing problem of motor vehicle and bicycle separated running in the four-legs intersection, promptly in the primary plane road junction, article two, the arterial highway possesses the Four-Lane Road road surface, or an arterial highway possesses the Four-Lane Road road surface, another arterial highway possesses the approach system of three-line pavement, take the grade separation form that on the bridge of directed intercommunication travel in the motor vehicle one-way road, solve between the motor vehicle and the traffic problems of motor vehicle and bicycle separated running.
And the patent No. is 97107088.1 " single-layer annular overhead overpass ", is a kind of single-layer annular overhead overpass, is made up of viaduct, access bridge, annular Zhi Gandao.Article one, highway viaduct and two ends access bridge thereof and ground major trunk roads form graded crossing, and viaduct is connected by annular Zhi Gandao with the ground major trunk roads, and annular Zhi Gandao travels as right-hand bend in the outside, travel for tuning in the inboard.Characteristics of the present invention are that the access bridge slope is long, and ramp angle is little, also do not influence the cruising of vehicle even tuning detours.
Recently, there is the people to propose 98100744.9 the patent application of " bi-directional symmetrical back-bending type vehicle classification is isolated the without hindrance capable overpass bridge of all directions " by name again.This invention relates to narrow intersection, a kind of city bi-directional symmetrical back-bending type vehicle classification and isolates the without hindrance capable overpass bridge of all directions.Make motor vehicle and bicycle spaced-apart under it will not expand the situation of intersection in the city, and they can be to all directions unobstructed travelling simultaneously between separately at road junction.One deck bridge that is linked to be integral body that this invention is mainly erected by intersection and each road stretch face top and on mutually antisymmetric two roads of direction across back bending bridge and a straight-through bridge across the intersection combine, though it can partly save urban road crossing land used and fund, has improved the bus capacity at crossing.But all still existing, above-mentioned all schemes need to take bigger area at road prong place, remove its building on every side in large area, and the prong vehicle is concentrated, it is more anxious to turn, distance between each bar branch road is shorter, be easy in this bottleneck of prong, because of dodging not as good as the deficiency that traffic congestion or collision accident etc. take place.
Goal of the invention of the present invention is to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, and it is comparatively convenient to make, and is useful on the existing road and sets up, even and also can prevent the urban road freely-moving bridge of the stifled resistance of vehicle effectively at comparatively narrow place, fork road.
Goal of the invention of the present invention mainly is achieved by following technical proposals: described pontic be arranged on the nearly prong road across bridge, and be provided with along the both sides of road and ramp across the tangent company of bridge.That is to say that described ramp incision section is parallel to the center line of road, and is then perpendicular with the center line of road across bridge.And described being across the road between bridge and prong dredged the highway section.At this moment, described ramp is arranged on across the road both sides between bridge and prong, and with arcuation across bridge cut-grafting mutually.And described arcuation can be the bridge of circular arc across bridge, also can be tangent, the transition of circular arc to the same side for the two ends of straight type bridge, can successfully turn round operation to be more conducive to vehicle.
In condition when permission, be set, also this mediation highway section can be being changed into and be in conplane mediation bridge, in order to avoid vehicle constantly crosses across bridge up and down, though so can further reduce total manufacturing cost across bridge.A kind of typical structure of this moment is: across the bridge two ends mediation bridge of trend prong is set described, and by mediation bridge and another is across the tangent company of bridge.Usually, described mediation bridge with make one across bridge, and be provided with along the both sides of road.The intervention of this mediation bridge, it is comparatively complicated to seem the structure that makes overpass bridge, blocks up the key point of thwarting topic in this bottleneck of road prong but the real the present invention of being solves vehicle effectively.Because this makes and is built, the appearance car zone of the comparatively narrow prong of landform restriction has enlarged manyfold virtually, make the vehicle of high-speed cruising can unimpededly pass through mediation bridge (road), and continue to sail unimpededly to each bar road.
Be provided with waiting platform in described rising ramp and between across bridge; And describedly be with it dorsad arcuation bridge across bridge.The outlet of described waiting platform is advisable laterally to cut along the mediation bridge.At this, the effect of described waiting platform both had been beneficial to the importing of bridge vehicle, had increased the quantity that the grade separation pontic holds vehicle again, had avoided the vehicle to stagnate in possible generations of phenomenon such as rising ramps.
Overpass bridge of the present invention can be the bicycle road, also can be two-way traffic, and its size, shape etc. can be decided according to the present situation of vehicle flowrate, road and prong.Wherein a kind of preferable technical scheme is: described across bridge semicircular in shape shape; The length of described mediation bridge is advisable with 50-120 rice, and respectively dredges bridge and be connected through circular-arc bend near the road prong.
When mutual distance is nearer between the intersection freely-moving bridge more than two or two, can it be connected as a single entity by the mediation bridge that is provided with along the road both sides.The vehicle that travels on this intersection freely-moving bridge can arbitrarily be driven towards on arbitrary cross road with extending in all direction.
Usually, describedly adopt steelwork, and set up column and the spud pile Joint that is preset on the road by tubulose across bridge or mediation bridge system.Perhaps, set up column and the steel box section that be provided with thereunder nonmotorized vehicle lane on above Joint across bridge or mediation bridge by tubulose with described.Like this, intersection freely-moving bridge of the present invention can be used comparatively easy structure and less investment, solves the unobstructed problem of travelling of dolly that accounts for absolute majority pointedly.Certainly, also can adopt existing known structure, material and erection technique to realize technique scheme.
Therefore, the present invention has rational in infrastructure, and it is comparatively convenient to make, and floor space is little, and the bridge construction cycle is short, cost saving, and running route is reasonable, and it is wider to be difficult for applicability, even and also can prevent characteristics such as the stifled resistance of vehicle effectively at comparatively narrow place, fork road.Like this, can form vehicle, bicycle and pedestrian does not disturb mutually, two plane freely-moving bridges of no traffic lights, bicycle and pedestrian are then moving across under the bridge, passenger vehicle, lorry and car travel on freely-moving bridge or the row original path, especially be useful on the location of not reserving the overpass bridge position in the former urban planning, build the intersection freely-moving bridge of no traffic lights.
