Abstract
The invention provides a road-railway overpass capable of preventing water logging and solves the water logging problem of the motor vehicle lane under the overpass. By the overpass, the road can be kept unobstructed under the condition of a rainstorm, the requirements for unobstructed roads of a modern city is satisfied. The road-railway overpass is characterized in that water retaining walls are disposed on two sides of the a railway bridge of the road-railway overpass, a water retaining protecting edge is disposed at the partition of the motor vehicle lane and a bicycle lane, a water retaining road is disposed at each access of the motor vehicle lane, each water retaining road is connected with the original motor vehicle lane through a slope, a water retaining sheds are disposed on the motor vehicle lane, edge openings are formed on two sides of each water retaining shed, and intervals are formed between every two water retaining sheds and between each water retaining shed and the railway bridge to guarantee the proper ventilation and lighting conditions of the road-railway overpass.
Description
Technical field
The present invention relates to a kind of public iron overpass bridge.
Background technology
Public iron overpass bridge is highway railway grade separation bridge, and general lower floor is highway, and upper strata is railway.Along with the continuous expansion of city size, urbanization step day by day quick, a large amount of population pours in city, thereupon, cause incity, city road traffic problem outstanding day by day, the public iron overpass bridge between city intramural railway and road has been forced out like this, and quantity is more and more.
Public iron overpass bridge has been alleviated the traffic pressure in city, but road under bridge is because physical features is low, and under bridge, forced-ventilated water system is limited in one's ability, and the water around when raining heavyly all flows into wherein and easily bears water, and it is flame-out that the lighter causes vehicle to paddle; Severe one has been flooded whole overpass bridge, has all flooded railway above soon, vast sea a slice, thus cause urban traffic to interrupt for a long time, its consequence is well imagined.
Summary of the invention
For above-mentioned situation, the invention provides a kind of public iron overpass bridge of anti-flooding, it can solve the problem that bears water of motorway under bridge, makes this road can be unblocked in heavy rain and heavy rain situation, to meet the needs that modern urban road is unimpeded.
The present invention is achieved in that the feature of the public iron overpass bridge of anti-flooding is: railway bridge two sides in public iron overpass bridge are established waterwall, dash formula safe edge is established in motorway and nonmotorized vehicle lane separated place in public iron overpass bridge, dash road is established in the access of motorway, dash road is connected with former motorway You Po road, on motorway, establish dash fluffy, two fluffy sides of dash are established bead, between the fluffy and dash of dash is fluffy, between the fluffy and railway bridge of dash, be provided with interval, to keep the due ventilation of public iron overpass bridge and daylighting condition;
Described motorway, is positioned at that track below railway bridge is other establishes drain, and drain will bear water discharge through collecting well by water pumper.
The minimum altitude of dash formula safe edge is not less than the height of dash road.
The height of dash road is higher than the height of local waterflooding.
Effect of the present invention is:
(1). under public iron overpass bridge, two sides of the import and export of motorway, motorway, motorway is all establishing above dash mechanism, the water of the surrounding after heavy rain can not be flowed into wherein, recycle the original strong drainage mechanism of this bridge, can keep it when heavy rain and heavy rain, not bear water, realize the needs that modern urban road is unimpeded.
(2). the dash formula safe edge on motor road, dash be fluffy also has sound insulation, keep off grey function, and vehicle can be passed through in the course of naturely, and traffic safety is secure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the stereogram of the public iron overpass bridge of anti-flooding of the present invention.
In figure: 1.Po road, 2. dash road, 3. motorway, 4. dash is fluffy, 5. railway bridge, 6. waterwall, 7. dash formula safe edge, 8. nonmotorized vehicle lane.
The specific embodiment
As shown in the figure, railway bridge 5 two sides in public iron overpass bridge are established waterwall 6, can stop the water on railway bridge 5 to flow on the road under bridge; Motorway 3 in public iron overpass bridge is established dash formula safe edge 7 with nonmotorized vehicle lane 8 separated places, and the minimum altitude of dash formula safe edge 7 is not less than the height of dash road 2, can stop the water of motorway 3 two sides to flow on the road under bridge; Dash road 2 is established in the access of motorway 3, and the height of dash road 2 is higher than the height of local waterflooding, and dash road 2 is connected with former motorway You Po road 1, and the water that can stop motorway 3 to import and export road flows on the road under bridge; On motorway 3, establish dash fluffy 4, two sides of dash fluffy 4 are established bead, between dash fluffy 4 and dash fluffy 4, be provided with interval between dash fluffy 4 and railway bridge 4, motorway 3 is positioned at the other drain of establishing in railway bridge 5 track below, drain will bear water discharge through collecting well by water pumper, so both keep the due ventilation of public iron overpass bridge and daylighting condition, and stoped again water large, heavy rain exceed the original forced-ventilated outlet capacity of this bridge and bear water.
Structure of the present invention is not limited to form described in embodiment, and the further expansion that those of ordinary skill in the art makes according to the present invention all falls into protection scope of the present invention.
The public iron overpass bridge of anti-flooding of the present invention can be transformed and form on existing public iron overpass bridge basis, and the difficult problem easily bearing water to solve former public iron overpass bridge, safeguards the traffic order of modern city.
