Abstract

The utility model relates to a left-turn overpass comprising through lanes and right-turn lanes, bridge approaches and viaducts in the east, the west, the south and the north directions; the through lane from east to west, the through lane from west to east, the through lane from south to north and the through lane from north to south are respectively arranged on the ground; left-turn lanes in the east, the west, the south and the north directions pass the bridge approaches and the viaducts from the ground and are connected with the ground in the other direction; various vehicles pass the viaduct from the ground and directly turns left to converge into the lanes. The bridge approach on two ends is connected with a section of smooth viaduct; vehicles pass right-turn ramps and turn right. The left-turn bridge approaches in the east, the west, the south and the north directions have the same height in the highest points. The utility model has the advantages of simple structure, few levels, small gradient construction, small difficulty, small fund-consumption, small floor area, less power-consumption and low cost; no traffic jam appears in the vehicle confluence.

Description

The left-hand rotation overpass bridge

Technical field

The utility model relates to a kind of overpass bridge, particularly relates to a kind of left-hand rotation overpass bridge.

Background technology

As everyone knows, at present, establish overpass bridge at the intersection place and solve vehicle safety and turn to the existing overpass bridge level of problem many, the cost height, floor space is huge.And added turning lane is a right-turn lane, if when turning left to bridge the track from track under the bridge, the climbing bend that clover is lobate of must turning right could arrive track on the bridge; If turn left from track on the bridge under bridge during the track, the back that also needs the to pass a bridge descending bend that clover is lobate of turning right could arrive track under the bridge.Simultaneously, when left turning vehicle enters the craspedodrome road after left-hand rotation, there is vehicle to turn right just, is easy to occur stopping up at place, vehicle interflow.

Summary of the invention

Main purpose of the present utility model is to overcome above deficiency and provides a kind of level few, and the construction gradient is little, and is expensive few, the left-hand rotation overpass bridge that power consumption is few.

The technical scheme that its technical problem that solves the utility model adopts is: it comprises east, the west, south, north is respectively to direct lane, right-turn lane and viaduct, it is characterized in that: described direct lane from east to west 1, direct lane 2 from west to east, direct lane 3 from south to north, be separately positioned on ground by north orientation south direct lane 4, east, when turn left to various vehicles in the west, from east, the west to ground to left-hand rotation access bridge 5,6 directly turn left to import the track, ground of other direction, south, when turn left to various vehicles in the north, from south, the north to ground to left-hand rotation access bridge 7,8 directly turn left to import the track, ground of other direction, east through viaduct 9, the west, south, the north access bridge 5 of respectively turning left, 6,7,8, the peak height identical.

Advantage and the good effect that the utlity model has are: simple in structure, level is few, and place, vehicle interflow clogging can not occur, and the construction gradient is little, and difficulty is little, and expensive few, floor space is little, and power consumption is few, and cost is low.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Among Fig. 1: 1. direct lane from east to west, 2. direct lane from west to east, 3. direct lane from south to north, 4. by north orientation south direct lane, access bridge, 6. west left-hand rotation access bridge in the east 5. turn left, 7. south left-hand rotation access bridge, 8. north left-hand rotation access bridge, 9. viaduct, 10. right-hand rotation ring road.

The specific embodiment

For further understanding summary of the invention characteristics of the present utility model and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1.

As shown in Figure 1: the utility model comprise East, West, South, North each to direct lane 1,2,3,4, East, West, South, North respectively turn

left access bridge

5,6,7,8, viaduct 9 and right-hand rotation ring road 10, described direct lane from east to west 1, direct lane 2 is separately positioned on ground from west to east, from south to north direct lane 3, be separately positioned on from ground through viaduct 9 by north orientation south direct lane 4 and import the tracks, opposite; When turn left to various vehicles in east, west, directly turn left to import the track, when turn left to various vehicles in south, the north, directly turn left to import the track by viaduct 9 and left-hand rotation access bridge 8,7 by left-hand rotation access bridge 6,5.Vehicle is turned right by right-hand rotation ring road 10.Respectively the turn left peak height of

access bridge

5,6,7,8 of East, West, South, North is identical.

Its advantage is: simple in structure, level is few, and place, vehicle interflow clogging can not occur, builds The gradient is little, and difficulty is little, and expensive few, floor space is little, and power consumption is few, and cost is low.

Claims

1. left-hand rotation overpass bridge, it comprises east, the west, south, north is respectively to direct lane, right-turn lane and viaduct, it is characterized in that: described direct lane from east to west (1), direct lane (2) from west to east, direct lane (3) from south to north, be separately positioned on ground by north orientation south direct lane (4), east, when turn left to various vehicles in the west, from east, the west to ground to left-hand rotation access bridge (5), (6) directly turn left to import the track, ground of other direction, south, when turn left to various vehicles in the north, from south, the north to ground to left-hand rotation access bridge (7), (8) directly turn left to import the track, ground of other direction through viaduct (9), east, the west, south, the north access bridge (5) of respectively turning left, (6), (7), (8) peak height is identical.
