Description

Low span-depth path separate passing through inter change cross junction

Technical field

The invention belongs to a kind of cross intersection and improve, especially low span-depth path separate passing through inter change cross junction.

Technical background

The development of human economy and technology participates among social production and the life automobile more and more in a large number, and it brings busy to urban road network traffic and blocks up.In the prior art; Urban road intersection also often adopts graded crossing when signal management can not adapt to busy stream of people's wagon flow; Existing graded crossing is provided with pedestrian or driving individual event construction; Genuine and the expressway overpass bridge etc. like the pedestrian's street crossing overline bridge also has the pedestrian to drive a vehicle and unifies the graded crossing of body.In the city; It is all quite busy that intersection is built dense stream of people's wagon flow; The unification graded crossing normally divides folded multilayer to set up and connects many built on stilts ring roads but existing pedestrian drives a vehicle; Not only the scale of construction, engineering and costly also makes pedestrian's loaded down with trivial details inconvenience of driving a vehicle, so although yet the bustling lively intersection in city quite has demand to be difficult to hold also rare application of seeing.Chinese patent " direct overrun flat tura city interchange cross road " (200410067097.4; 200420090955.2) design use straight-through stride bridge pacifically ring road combine effectively to simplify the road graded crossing, so be applied in the business district pedestrian and cross over the intersection and also have more inconvenience and conflict.Chinese patent " the high variable short slope road overpass bridge of main span " (200610052571.5; 200620105865.5) design utilization breaks through the existing road and bridge beam standard of striding and reduce the high thinking of clear span, opened up to stride the road and bridge beams and dwindle the occupation of land scale significantly and save cost, reduce the vehicular traffic climbing in a large number and consume the new way that reduces exhaust emission.

Summary of the invention

Order of the present invention ground is that a kind of low span-depth path separate passing through inter change cross junction will be provided; Optimize through innovation the dedicated channel position ingenious arrangement pedestrian path of driving a vehicle is set; Graded crossing structure is simplified take up an area of and is dwindled widely applicable economic environmental protection, let each to pedestrian and vehicle via rationally passing through easily and turning to the passage realization of taking their own roads unimpeded in order.

The objective of the invention is to realize like this: it is to form sidewalk, pedestrian's passage lanes, avris at vertical road of cross intersection to turn to passage, lowly stride that high passage lanes, centre turn to passage, lowly stride high passage lanes, avris turns to passage, pedestrian's passage lanes, sidewalk positional alignment for a low span-depth path separate passing through inter change cross junction; The level land ring road, is striden high passage lanes and is constituted with sidewalk and the roadway that People's Bank of China's passage lanes passes through the belt road that intersects from underground, semi-underground or ground by low to road and belt road around the inboard building of intersection corner or green land connection lengthwise.Said pedestrian's passage lanes is the passage of walking from pedestrian underground, semi-underground or that pass through on the ground intersect belt road sidewalk and roadway; Hang down and stride high passage lanes for pass through the high driving of the low clear span passage that is lower than the Overheight Vehicles elevation of intersect belt road sidewalk and roadway from underground, semi-underground or ground.It is to be positioned at sidewalk avris connection lengthwise to the driving passage of road with the belt road that intersects that said avris turns to passage; The centre turn to passage be in vertical road midfeather in two low connection lengthwise of striding between the high passage lanes to the driving passage of road with the belt road that intersects; The level land ring road is to the ground of road and belt road garage passage around the inboard building of intersection corner or green land connection lengthwise.At low span-depth path separate passing through inter change cross junction; Vertically road is to pass through belt road through pedestrian's passage lanes to the pedestrian directly; Craspedodrome motor vehicles and non power driven vehicle are striden high passage lanes and are passed through belt road through low; The right-hand rotation motor vehicles turn to the passage non power driven vehicle to turn to passage to turn to into belt road through avris and go through the centre, the motor vehicles that need and non power driven vehicle are striden high passage lanes and passed through belt road ring road detours and changes direction entering belt road and go through the level land again from low earlier.On belt road; Motor vehicles of keeping straight on and non power driven vehicle are kept straight on without hindrance; The right-hand rotation motor vehicles turn to the passage non power driven vehicle to turn to passage to turn to into vertical road driving through avris through the centre, the motor vehicles of left-hand rotation and non power driven vehicle are kept straight on and striden across vertical road ring road detours and changes direction and get into vertical road driving through the level land again.Low span-depth path separate passing through inter change cross junction has been realized the simple overpass intercommunication; But on belt road, also exist a little craspedodrome pedestrians and turn right motor-driven and bicycle and craspedodrome bicycle and right-hand rotation motor vehicle that the traffic skirmish of at grade intersection is arranged; Yet numerous branch roads intersection and cross walk need not to establish traffic administration in urban road, specially the road separate, sparse dispersion and the vehicle that turns to deceleration with pass through the pedestrian and all adopt active to dodge separately not hinder fully in unimpeded.

Low span-depth path separate passing through inter change cross junction is optimized through innovation dedicated channel position ingenious the arrangements pedestrian path of driving a vehicle is set, and makes cross graded crossing structure simplify the environmental protection of occupation of land reduction capability overall economic.It is to break through the existing high the principle of economizing of road and bridge beam standard reduction clear span of striding; The low rare Overheight Vehicles in high passage lanes restriction city of striding are set to be passed through; Shortened the ramp and reduced the grade separation scale and saved building costs and improved applicability, the exhaust environment pollution has been lowered in the climbing energy consumption that has more reduced countless vehicular traffic.It is used the level land ring road and makes the simple intercommunication in intersection; Turn to passage in the middle of in the middle of road, being provided with especially again; The motor vehicle of both having avoided turning right conflicts with the lane change of craspedodrome bicycle; Turn in the middle of can also making passage to become the occasional passage that idol has Overheight Vehicles, realize each to Pedestrians and vehicles take their own roads unimpeded.
