Abstract

A T-junction flyover with pedestrian and vehicle lanes mainly solves the problems of large floor area, high cost and the like as existing T-junctions have no flyover and left turns of the existing flyovers mostly adopt a right detouring method. The T-junction flyover with the pedestrian and vehicle lanes comprises an air flyover, an underground flyover, and coming and going direction and left-to-right or right-to-left direction straight lanes levelly intersected with the ground, and left or right turning lanes in three directions. The T-junction flyover with the pedestrian and vehicle lanes has the advantages that the air flyover is combined with the underground flyover; left and right turning and straight traveling are natural and smooth; level intersection of a non-motor vehicle and a pedestrian is not hindered; and the overall design is compact and ingenious. Due to the fact that a three-dimensional crossing mode combining underground and air and a design mode that a lane width is preserved in the middle of a straight motorway and left-turning and right-turning lanes are directly led out from the straight motorway are adopted originally, the floor area is greatly reduced and the width of the flyover can be as small as that of four lanes; the T-junction flyover can be constructed at the T-junction which is 3.5m wide (including a non-motor vehicle lane and a sidewalk), and the number of the motor vehicles in each direction also can be increased according to the width of a street.

A. north and south (or thing) direction craspedodrome motorway frame is in the top of ground level crossing (I type) or from the underground ground level crossing (II type) that passes, the left and right turning roadway of east orientation west (or north orientation south, west eastwards, south orientation is northern) direction craspedodrome motorway and extension thereof is from underground ground level crossing (I type) or the frame of passing in the top of ground level crossing (II type), and the two and ground line are graded crossing;

B. the right-hand bend motorway of south east (or north east, north west, west south) direction is directly drawn from the craspedodrome motorway, by access bridge or gentle slope from striding across (I type) in the air or from underground passing (II type) ground level crossing, merge with the left turn lane of north orientation east (or west northwards, south orientation west, east orientation be southern) direction, then incorporate the craspedodrome motorway into;

C. the right-hand bend motorway of north east (or north west, west south, south east) direction is directly drawn from the craspedodrome motorway, from underground passing (I type) or from striding across craspedodrome motorway and the ground level crossing of (II type) direction that intersects in the air, then incorporate the craspedodrome motorway by gentle slope or access bridge into;

D. east orientation south (or north orientation east, west northwards, south orientation is western) direction left-hand bend motorway is directly drawn from the craspedodrome motorway, from underground passing (I type) or from striding across craspedodrome motorway and the ground level crossing of (II type) direction that intersects in the air, then incorporate the craspedodrome motorway by gentle slope or access bridge into;

E. north orientation east (or west northwards, south orientation west, east orientation be southern) direction left-hand bend motorway is directly drawn from the craspedodrome motorway, by access bridge or gentle slope from striding across (I type) in the air or from craspedodrome motorway and the ground level crossing of underground passing (II type) relative direction, merge with the right-hand bend motorway of relative direction, then incorporate the craspedodrome motorway into;

F. nonmotorized vehicle lane and sidewalk keep ground usual friendship mode.

2. pedestrian and vehicle separation overpass at T-junction according to claim 1 is characterized in that:

A. a lane width distance in the middle of the same craspedodrome motorway is for the graded crossing of left and right turning motorway and the merging of overpass bridge;

B. according to street width, tunable increases, reduces motor vehicle direct lane number that each flows to, and also can be not will not turn right and the left-hand bend motorway merging of other direction.

C. depth stop and aerial limit for height situation, flexible choice I type or II type under the base area.

The utility model has the advantages that: by the aerial and underground graded crossing modified line that combines, and same road surface comes, goes a lane width distance reserving between the motorway, realizes the left and right turning of motor vehicle, motor vehicle is left and right turn to and the nature of keeping straight on smooth and easy; Left and right turning motorway is directly drawn from the craspedodrome motorway, all reduced the occupation of land width, so that global design is compact, floor space almost reaches bottom line, 4 lane widths of the minimum only need of motorway part, (comprising nonmotorized vehicle lane and sidewalk) just can be built in 35 meters wide crossings.Design has originality, and is novel ingenious, scientific and reasonable, practical.
