Abstract

The utility model provides a low-span fully intercommunicating overpass: above the original road surface of a road-cross, a cross-shaped low-span bridge is bridged. The bridge surface of the intercrossing point of the road-cross is built on the original road surface for certain headroom, the height of which allows the pedestrian and non-automobile passage. On the horizontally and vertically crossed bridge surface of the low-span bridge, a U-shaped ramp is separately built over the none-automobile and pedestrian passages on both sides of the original road surface: the ramp faces the bridge-head from the entrance upward to the crossed low-span bridge, and then turns a large-swerve to cross the original horizontal road surface, and then turns back downward above the offside pedestrian passage, and then connected to the horizontal offside bridge surface of the crossed low-span bridge. The headroom of the swerving point of the U-shaped ramp from the ground is at the height of allowing the passage of automobiles. Besides, the inner side of the U-shaped ramp is provided with another small U-shaped ramp, between the entrance of which and the large U-shaped ramp, a driveway for straight-going or right-turning is arranged. The direction of the small U-shaped ramp is identical to that of the large U-shaped ramp and connects with the large U-shaped ramp upward to the swerving point of the bridge-head.

Description

The low intercommunicated overpass of striding

Technical field

The utility model relates to a kind of overpass bridge.Especially the low intercommunicated overpass of striding.

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 all build overpass bridge in intensive a plurality of crossroads, with thorough alleviation traffic pressure in the city.

Summary of the invention

In order to overcome above-mentioned shortcoming, the utility model provides a kind of hanging down to stride intercommunicated overpass, and this bridge number of plies is few, short bustling crossroad, the city bridge construction that is adapted at most of access bridge.

The technical scheme that its technical problem that solves the utility model adopts is: in the sky, the former road surface of cross mouth, set up the low bridge of striding of a cross, cross mouth intersection bridge floor is from former road surface headroom, for allowing People's Bank of China and bicycle headroom, about about 2.5 meters.Stride on the bridge floor that bridge crosses anyhow low, each former road surface bicycle and sky, sidewalk to the left and right sides, each minute built a U-shaped ring road: upwards hang down to cross from the entrance and stride the horizontal end of the bridge of bridge, the big turning strides across former lateral road road surface, turn round again downwards to the sky, offside sidewalk, until striding the horizontal offside bridge floor of bridge and join with cross is low, U-shaped ring road turning overhead headroom for allowing motor vehicle by height, about about 5 meters.In U-shaped ring road inboard, build a little U-shaped ring road more in addition, between its arrival end and the big U-shaped ring road, one as the descending track of keeping straight on or turning right at interval, and little U-shaped ring road trend is identical with big U-shaped ring road, goes upward to the end of the bridge turning and promptly is harmonious with big U-shaped ring road.

The beneficial effects of the utility model are: 1. not newly-increased soil, the roadside buildings of not removing, 2. level is few, and access bridge is short, save oil plant, 3. full intercommunication, the non-separation of machine is taken their own roads, 4. pedestrian and bicycle are all directly current down from bridge, need not go up overline bridge or following tunnel, 5. can make full use of overhead space, sidewalk, making the crossroad narrower in the city set up intercommunicated overpass becomes possibility.

Description of drawings

Below in conjunction with drawings and Examples the utility model is done step explanation: Fig. 1 is the utility model panorama schematic diagram, and Fig. 2 is the utility model floor map, and Fig. 3 is the utility model elevational schematic view.Fig. 4 is the utility model schematic side view.

1. former cross road lateral road road surfaces among the figure, 2. former cross road erects road surface, 3. cross hangs down and strides bridge lateral road bridge floor, 4. the low perpendicular road of the bridge bridge floor of striding of cross, the 5. big U font in outside ring road, 6. inboard little U font ring road, 7. right-hand rotation straight channel, 8. outside U font ring road enters the mouth, 9. outside U-shaped ring road outlet, 10. inboard U-shaped ring road inlet.11. inboard U-shaped ring road outlet, 12. People's Bank of China and nonmotorized vehicle lane.

The specific embodiment

In Fig. 2, present embodiment sets up the low bridge of striding of a cross in the sky, the former road surface of cross mouth, and cross mouth intersection bridge floor is from former road surface headroom, for allowing People's Bank of China and bicycle headroom, about about 2.5 meters.Stride on the bridge floor that bridge crosses anyhow low, each former road surface bicycle and sky, sidewalk (12) to the left and right sides, each minute built a U-shaped ring road (5): (8) are upwards to the low bridge lateral road end of the bridge of striding of cross from the entrance, the big turning strides across former lateral road road surface (1), turn round again downwards to the sky, offside sidewalk (12), until striding the horizontal offside bridge floor of bridge and join (9) with cross is low, U-shaped ring road turning overhead headroom for allowing motor vehicle by height, about about 5 meters.In addition in U-shaped ring road inboard, build a little U-shaped ring road (6) again, between its arrival end (10) and the big U-shaped ring road, one as the descending track (7) of keeping straight on or turning right at interval, little U-shaped ring road trend is identical with big U-shaped ring road, goes upward to the end of the bridge turning and promptly is harmonious with big U-shaped ring road.

As shown in the figure: the craspedodrome of making a return journey of crossrange maneuvering car, finish by the horizontal track of cross bridge floor (3), turn right then by the passage aisle (7) in the middle of two U-shaped ring roads of size, directly going up the bridge right-hand rotation finishes, turn left then to pass through the arrival end (10) of inboard little U-shaped ring road (6), last ramp bridge is turned right to the port of export (11) and is finished.

The longitudinal maneuver car, making a return journey keeps straight on then passes through the arrival end (8) of the big U-shaped ring road in the outside (5), and last bridge is turned right to the port of export (9) and is finished; Right-hand rotation is then by the passage aisle (7) between the inside and outside U-shaped ring road, and bridge (3) was finished under last bridge (4) was turned right; Turn left then to pass through the arrival end (10) of inboard little U-shaped ring road (6), last bridge directly moves ahead to the port of export (11) and finishes.

Pedestrian and non motorized vehicle then directly strides by cross is low that the bridge opening has free passage under the bridge bridge.
