Abstract
Safety railway road junction is composed of junction paved road, acceleration road and alarm road, before a vehicle runs over a level crossing of railway, it runs over the alarm road at first, the alarm road prevents the vehicle from trying to overtake the train and prevents the engine from turning off at the junction, the driver should decrease the speed look round at both ways to make sure that when no train crossing, then he runs on the acceleration road and increase the speed to cross the junction as soon as possible.
Description
The present invention relates to the design at a kind of public iron level crossing road junction, the design that reduces public iron level crossing level crossing accident, ensures the Rail Highway safe operation can be provided.
Public iron level crossing road junction will exist for a long time in large quantities in many countries and regions in the China and the world.Slab and both sides slab should adopt the precast concrete slab to be paved into and rail level one flat, smooth stable paving by designing requirement in the middle of the current now public iron level crossing road junction.But there are many road junctions still to adopt ashlar or waste and old sleeper to do paving and very unfairness of paving; Now the design and construction pair highway that is connected with the both sides slab at public iron level crossing road junction is not then taked any measure from secure context, mostly the highway that is connected with the both sides slab is smooth.The unfairness in paving, level crossing makes the vehicle generation severe jolt that travels on it and is difficult for passing through, and extrahazardous is to be easy to make self-propelled vehicle top fire extinguishing horizontal stroke on the line, causes the serious accident of car crash; Smooth highway pavement makes the road vehicle chaufeur weaken the vigilance of train not to be noted watching from a height or a distance, also strive the capable condition of having created of robbing for some automobile driver and train easily.
The purpose of this invention is to provide a kind of make the road vehicle navigating mate before driving to sail railway clearance into, strengthen to train vigilant, note watching from a height or a distance, prevent from that self-propelled vehicle from putting out a fire on the line and strive to rob capable design with train.
The present invention is achieved in that the rail segment at public iron level crossing road junction adopts " the rail track grade crossing pavement structure " stipulated in the Railway Design standard drawing to require design and construction, must guarantee concrete prefabricated slab plate face and rail rail level one flat and good stability; What link to each other with the both sides precast concrete slab of rail track is one section smooth road surface, is called to quicken the road surface; With what quicken that the road surface links to each other is one section uneven road surface that is paved into ashlar piece or precast concrete block or other road-making material, is called and warns the road surface; What link to each other with the warning road surface is the normal highway road surface that vehicle can cruising.
Describe the present invention below in conjunction with accompanying drawing.
With reference to accompanying drawing.(1) be the middle slab of precast concrete of the rail track grade crossing pavement structure division of standard, (2) are guard timbers, and (3) are the rail faces, and (4) are precast concrete both sides slabs.The plate face of the plate face of slab (1), guard timber (2), paving, both sides (4) is all concordant and stable with rail rail level (3) in the middle of must guaranteeing when requiring construction.(6) be to be connected with paving, both sides (4) and the acceleration road surface concordant with the plate face: its length is not less than highway, and total length, institute's lade of long vehicle allow to exceed length and edge, paving, both sides (4) the length sum to railway clearance (5).Regulation is for guaranteeing that vehicle passes through the level crossing, when driving to warning road surface (7) on quickening road surface (6), breaking away from railway clearance (5) reliably like this.(7) with quicken road surface (6) and be connected, be paved into ashlar piece or precast concrete or other road-making material, surface irregularity, make vehicle ' on it generation necessarily jolt, be called and warn the ground-surface road surface.Its length is not less than the wheelspan of the vehicle of wheelspan maximum on the highway.Regulation is in order to make car load be in the state of jolting like this.(8) be the normal highway road surface that is connected with warning road surface (7).
When vehicle driver on the highway drove to be reached warning road surface (7) and gone up by normal road surface (8), road surface (7) is rough and uneven in surface to force the navigating mate jogging of must slowing down owing to warn, and then must use low grade instead and travel concerning self-propelled vehicle.Can warn in advance so promptly that the navigating mate front is that railway should be noted watching from a height or a distance and has or not train to come, can prevent from effectively also that road vehicle navigating mate and train from striving to rob row; Self-propelled vehicle is forced to use instead low grade and travels and then can prevent self-propelled vehicle " fire extinguishing " on railway effectively.When chaufeur passes through warning road surface (7), after confirming that no train reaches acceleration road surface (6), because it is all flat with rail face (3) to quicken road surface (6), paving, both sides (4), guard timber (2) and middle paving (1), vehicle just can quicken, evenly early by this danger zone, level crossing.
Claims (3)
1, a kind of rail/road grade crossing safety traffic design, comprise " the rail track grade crossing pavement structure " stipulated in the Railway Design standard drawing, quicken road surface (6) and warning road surface (7), it is characterized in that quickening road surface (6) and be connected with the precast concrete both sides slabs (4) of " rail track grade crossing pavement structure ", warning road surface (7) is connected with acceleration road surface (6).
2, the design of rail/road grade crossing safety traffic according to claim 1 is characterized in that quickening road surface (6) length and is not less than highway total length, institute's lade of long vehicle allow to exceed length and edge, paving, both sides (4) the length sum to railway clearance (5).
3, rail/road grade crossing safety traffic according to claim 1 design, it is characterized in that warning road surface (6) to be paved into ashlar piece or precast concrete block or other road-making material making the not too serious rough and uneven in surface shape that jolts of vehicle generation, its length is not less than the wheelspan of the vehicle of wheelspan maximum on the highway.
