Abstract

The utility model discloses a barbell form flyover crossing. The vertical lane of the original crossing is provided with a bow shaped single span running up until the non-motorized vehicles and the people can pass, which is about 2.5m, at the right side, a right-turning ramp runs down and is connected with the vertical lane and stops at the crossing; the both sides of the horizontal lane under the vertical overpass of a bow form is provided with a U form ramp; the entrance terminal is arranged on the second lane at the right side of the horizontal lane and runs up to the height until the non-motorized vehicle can pass and turns left and strides the horizontal lane to run down and affluxes to the second lane of the horizontal lane and stops at the crossing; the vertical single span is closely near the outer vertical left-turning passage of the right-turning ramp, the position of which is parallel to the ground and is connected with the U form ramp. The effect of the utility model is 1. The utility model is not necessary to increase area and remove the constructions on the wayside; 2. The construction has a plurality of levels, a short bridge approach, which can save oil; 3. The utility model is smooth all the way, and the motorized and non-motorized vehicle is divided and runs on separated lanes.

Description

The bar-bell type intercommunicated overpass

Technical field

The utility model relates to a kind of overpass bridge.Especially bar-bell type intercommunicated overpass.

Background technology

Existing overpass bridge level is many, and floor space is big.Even as international application for patent number is PCT/CN 03/00269, China Patent No. is 02222131.X semi-underground four aspect overpass bridges, 02222231.6 half heavy interior ring type overpass bridge A, Type B, not only be four layers, access bridge is long, but also will hole down, can only build in the countryside mostly, can't solve the urban transit system congestion, more can't build overpass bridge, with thorough alleviation traffic pressure in the crossroad of city prosperity.

Summary of the invention

In order to overcome above-mentioned shortcoming, the utility model provides a kind of bar-bell type intercommunicated overpass just can reach the purpose of setting up overpass bridge in bustling crossroad.

The technical scheme in the invention for solving the technical problem is: at original path and the overhead bar-bell type intercommunicated overpass of forming in the overhead bridge floor of original path, on vertical road surface, former crossroad, set up an arc simple span bridge, height when crossing over the sky, horizontal road surface, for allowing the minimum altitude of autos only, about 5 meters.Simple span bridge to go upward to allow under the bridge bicycle and pedestrian by the time about 2.5 meters, promptly tell the descending and vertical road surface of right turn ramp on the right side and join and terminate in the crossroad; On horizontal road surface, both sides under vertical arc high overbridge bridge, respectively set up a U-shaped ring road, arrival end is positioned at second track, lateral road right side, when upwards extremely highly passing through height for the permission motor vehicle, turn left to stride across lateral road and turn round again downwards, until importing lateral road road surface offside second lane and terminating in the crossroad; Vertically simple span bridge is near vertical left-hand rotation passage of outside right-hand rotation ring road, and ring road is told to the right again in its position when crossing over lateral road, be parallel to ground, until with the tandem mutually of U-shaped ring road.

The invention has the beneficial effects as follows: 1. not newly-increased soil, the roadside buildings of not removing makes full use of overhead space, sidewalk; 2. level is few, and access bridge is short, saves oil plant; 3. full intercommunication, the non-separation of machine is taken their own roads.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples: Fig. 1 is the utility model panorama schematic diagram, and Fig. 2 is this bridge of the utility model floor map, and Fig. 3 is the utility model elevational schematic view, and Fig. 4 is the utility model schematic side view.

1. former vertical tracks among the figure, 2. former horizontal track, 3. vertical simple span bridge, 4.U shape ring road, 5.U shape ring road inlet, the outlet of 6.U shape ring road, the 7. little arc bridge of striding of right-hand rotation ring road, 8. vertically left rotaring ring road, 9. sidewalk and nonmotorized vehicle lane.

The specific embodiment

In Fig. 1 and Fig. 2, on vertical road surface, former crossroad (1), set up an arc simple span bridge (3), simple span bridge is to going upward to when allowing that bicycle and pedestrian pass through under the bridge, about 2.5 meters, promptly tell the descending and vertical road surface of right turn ramp (7) on the right side and join, and terminate in the crossroad; Main bridge continues to move ahead and crosses over the sky, horizontal road surface (2), and leap place headroom is for allowing the minimum altitude of autos only, about 5 meters.On horizontal road surface, both sides (2) under vertical arc high overbridge (3) bridge, respectively set up a U-shaped ring road (4), arrival end (5) is positioned at second track, lateral road right side, when upwards extremely highly passing through height for the permission motor vehicle, turn left to stride across lateral road and turn round again downwards, straight remittance lateral road road surface offside second lane is its outlet (6), and terminates in the crossroad; Vertically simple span bridge is the ring road of telling when crossing over lateral road to the right near turn right vertical left-hand rotation passage (8) of ring road (7) of the outside, is parallel to ground, until with U-shaped ring road (4) tandem mutually.

In Fig. 2, the motor vehicles of vertically making a return journey, it is without hindrance to make a return journey by bridge floor in the middle of the simple span bridge (3), the motor vehicles of laterally making a return journey, by former horizontal road surface (2) middle lane, it is without hindrance to make a return journey.

The longitudinal maneuver car is turned right, and then by the little arc bridge (7) of striding in vertical simple span bridge right side, directly turns right behind the following bridge and finishes.The longitudinal maneuver car turns left, and then by left rotaring ring road (8), walks to U-shaped ring road (4) crook and imports the U-shaped ring road, proceeds to the port of export (6) to directly moving ahead along ring road, realizes.

The crossrange maneuvering car is turned right, and then directly finishes by the right side, road.

The crossrange maneuvering car turns left, and enters U-shaped ring road arrival end (5) after then passing vertical simple span bridge (3) bridge opening, moves ahead around the big curved lateral road (2) that strides across, and revolution goes out the port of export (6) back downwards and turns right and realize.

Horizontal bicycle and pedestrian are then by having free passage under vertical simple span bridge (3) bridge.

Vertically bicycle and pedestrian can establish the tunnel or overline bridge passes through by other.

Claims

1, a kind of bar-bell type intercommunicated overpass, by the original ground road and overheadly form in the overhead bridge floor of original path, it is characterized in that: on vertical road surface, former crossroad (1), set up an arc simple span bridge (3), simple span bridge is to going upward to when allowing that bicycle and pedestrian pass through under the bridge, promptly tell the descending and vertical road surface of right turn ramp (7) on the right side and join, and terminate in the crossroad; Main bridge continues to move ahead and crosses over the sky, horizontal road surface (2), leap place headroom, for allowing the minimum altitude of autos only, on horizontal road surface, both sides (2) under vertical arc high overbridge (3) bridge, respectively set up a U-shaped ring road (4), arrival end (5) is positioned at second track, lateral road right side, when upwards extremely highly passing through height for the permission motor vehicle, turn left to stride across lateral road and turn round again downwards, directly import lateral road road surface offside second lane and be its outlet (6), and terminate in the crossroad; Vertically simple span bridge is the ring road of telling when crossing over lateral road to the right near turn right vertical left-hand rotation passage (8) of ring road (7) of the outside, is parallel to ground, until with U-shaped ring road (4) tandem mutually.
