Abstract

The utility model relates to a walkway driveway open ground combined overpass, which mainly solves the problems of the conventional overpass that the left turns usually take right roundabouts, the occupied area is large, and the cost is big, and includes aboveground crossing, underground crossing and ground level crossing type going, coming, left-right and right-left straight driveways (including non-motor way and walkway) and left and right turning driveways in four directions, and is characterized in that the non-motor vehicle way and the walkway are in ground level crossing; the going and coming or the left-right and right-left straight driveways of the motor vehicle pass from the overpass or under the ground; the going and coming and left-right and right-left left turn motor drive way and the below (underground crossing) or the above (aboveground crossing) left turn of the coming and going or right-left and left-right straight motor drive way are combined with right turn drive way in the opposite direction through a ground level and an approach bridge or a gentle slope, and are integrated into the straight motor drive way in the cross direction; the right turn drive ways of four directions are directly led out from the straight motor driveway, are combined with the left turn driveway in the opposite direction through the approach bridge or the gentle slope, and are integrated into the straight drive way in the cross direction. The walkway driveway open ground combined overpass has the advantages of the combination of aboveground crossing and underground crossing, smooth left-right turning and straight drive, doesn't influence the level crossing of non-motor and walker, highlights a thinking of human orientation, and is compact, novel and ingenious in integral design. As the underground and aboveground combined spatial crossing type is adopted, odd number of driveway width is assumed, and the right turn driveway is directly led out of the straight motor driveway, the occupied area is greatly reduced, 5 driveway width is seen as suitable, a 40-width crossing can be built (including non-motor way and walkway), and the number of the motor straight driveways for different directions can be increased according to the width of the street.

Description

Pedestrian and vehicle separation vacant lot combines overpass bridge

Technical field

The utility model belongs to a kind of overpass bridge, particularly a kind of novel overpass bridge that is applicable to that highway and urban road intersect.

Background technology

Present overpass bridge turns left to adopt right circuitous method more on structure design, thereby causes whole project occupation of land area big, and is inapplicable originally than the narrow lane mouth.The rotating disc type overpass bridge that has has three plotted points when turning left, occur vehicle scratching phenomenon easily, and especially the traffic congestion phenomenon appears in wagon flow peak period easily.The route of bridge is more random on the overpass bridge that has, and is not easy to driver's identification.

The utility model content

The purpose of the utility model provides a kind of novel pedestrian and vehicle separation vacant lot and combines overpass bridge; Utilize aerial grade separation and underground interchange to combine originally and method that odd number lane width, right-hand bend motorway are directly drawn from direct lane; With novel ingenious, scientific and reasonable with the Design Treatment of underground left-hand bend on the bridge, turn to about motor vehicle and the nature of keeping straight on smooth and easy, the global design compactness; Floor space seldom, fund input is less.

The purpose of the utility model realizes through following technical scheme: the motor vehicle that it comprises aerial grade separation, underground interchange and ground usual friendship three parts comes the direction direct lane, removes the direction direct lane, the right direct lane of left-hand, dextrad left side direct lane and the left and right turning roadway of four direction and bicycle and pedestrian's level crossing, it is characterized in that:

A. left-hand is right, dextrad is left and come direction, go direction craspedodrome motorway to pass the ground level crossing or pass the ground level crossing in the air from the ground from underground, and the two and ground line are graded crossing;

B. turn left motorway frame level crossing and relative direction craspedodrome motorway in ground the top or slip into the ground level crossing and the below of relative direction craspedodrome motorway;

C. the motorway of turning right is directly drawn from the craspedodrome motorway, through the left-hand bend motorway merging of access bridge or gentle slope and relative direction, incorporates the craspedodrome motorway of the direction that intersects then into;

D. the motorway that turns left merges through the right-hand bend motorway of access bridge or gentle slope and relative direction, incorporates the craspedodrome motorway of the direction that intersects then into;

E. nonmotorized vehicle lane and sidewalk keep ground usual friendship mode;

F. overpass bridge is taked the odd number lane width, goes, comes direction or the left-hand right side, the lane width distance of dextrad left in the middle of the craspedodrome motorway, supplies left-hand bend, the graded crossing of right-hand bend motorway of this overpass bridge and merge to use;

G. according to street width, tunable increases the motor vehicle direct lane number of all directions, also can be not with the left-hand bend motorway merging of turning right with relative direction.

The utility model has the advantages that: realize left and right turning through aerial with the underground graded crossing modified line that combines, left and right turn to and the nature of keeping straight on smooth and easy; Take odd number lane width, right-hand bend motorway directly to draw from the craspedodrome motorway; All reduced the occupation of land width; Make global design compact; Floor space almost reaches bottom line, 5 lane widths of the minimum only need of motorway part, and (comprising nonmotorized vehicle lane and sidewalk) just can be built in 40 meters wide crossroads.Design has originality, and is novel ingenious, scientific and reasonable, practical.

Annotate: the ground usual friendship part that does not relate to nonmotorized vehicle lane and sidewalk among the figure.

The specific embodiment

See Fig. 1,2,3,4, concrete structure is following: the utility model is made up of direct lane A, left turn lane B, right-turn lane C, nonmotorized vehicle lane D, the sidewalk E of four direction.Wherein, go, come direction direct lane A1, A2 frame on ground, the left-hand right side, the left direct lane A3 of dextrad, A4 pass from underground, in the middle of two relative direction direct lane A1, A2 centre and A4, the A3 a straight distance that the track is wide are arranged.Go, come direction left turn lane B1, B2 to pass through from the top of relative direction direct lane A2, A1 respectively, then merge with the right-turn lane C2 of relative direction, C1 respectively, reduce to ground through the gentle slope again through the gentle slope through viaduct; Left-hand is right, the dextrad left is turned left, and sweep B4, B3 pass from the below of relative direction direct lane A3, A4 respectively, is increased to its direct lane height through the gentle slope and merges with right-turn lane C3, the C4 of relative direction respectively, rises to ground through the gentle slope again.Go, come direction right-turn lane C1, C2 to draw from direct lane A1, A2 respectively, merge with the left turn lane B2 of relative direction, B1 respectively, then reduce to ground with overhead mode; Left-hand is right, the dextrad left bends to right, and track C4, C3 draw from direct lane A4, A3 respectively, and left turn lane B3, the B4 with the relative direction that reaches its direct lane height through the gentle slope merges respectively, then rises to ground.Nonmotorized vehicle lane D1, D2, D3, D4 and sidewalk E1, E2, E3, E4 keep the mode of ground usual friendship.
