Description

H type access bridge
Technical field
The present invention relates to a kind of road equipment, particularly a kind of multi-functional overpass bridge that is arranged in the urban road.
Background technology
Along with the rapid development of Chinese national economy, living standards of the people improve constantly, and the owning amount of compatriots' automobile improves rapidly with the speed that surpasses the road expansion far away.Therefore, urban road, the vehicle pass-through problem that especially is in urban road intersection is the key point that solves urban transport problems.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 for example, the someone has proposed 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.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.
On this basis, the people is arranged recently again, proposed to be provided with the patent application (number of patent application 01105942.7) of " the urban road freely-moving bridge " that can prevent the stifled resistance of vehicle effectively specially at the comparatively narrow and small road junction in city.This technical scheme is to the effect that: 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.Though it has also solved the problem of the stifled resistance of road junction vehicle to a certain extent, but because each only solves the commutation problem (for example can not on bridge bidirectional turn) of a direction vehicle on the road across bridge, promptly four of road prong needs are combined into an obturator across bridge around it and just can finish aforementioned goal of the invention, thereby exist cloth bridge amount bigger, cost is higher, not the technical problem of economic dispatch very.
