Abstract

The utility model relates to an urban crossroad flyover, belonging to the technical field of urban bridges. The urban crossroad flyover is composed of an approach bridge, a U-turn roundabout, a straight-going and left-turn roundabout and a right-turn ramp. The U-turn roundabout is arranged in the ground center of the crossroad; the straight-going and left-turn roundabout is erected at the outer side of the U-turn roundabout; a non-power-driven vehicle roundabout is arranged on the ground between an inner-layer stand column and an outer-layer stand column; the approach bridges between the U-turn roundabout and the straight-going and left-turn roundabout are connected through the right-turn ramp; the straight-going and left-turn roundabout is connected with the right-turn ramp through an up-bound traffic lane; and the straight-going and left-turn roundabout is connected with the motor vehicle lane through the downward lane. By adopting the U-turn roundabout, the right-turn ramp and the straight-going and left-turn roundabout, the purposes of U-turn, straight-going, left-turn and right-turn of motor vehicles are achieved, and non-power-driven vehicles and pedestrians can pass through the non-power-driven vehicle roundabout and pedestrian passage without barriers, thereby improving the utilization rate of roads as well as the travel speed and reducing the traffic accidents.

Description

Crossroad, a kind of city overpass bridge

Technical field

The utility model relates to crossroad, a kind of city overpass bridge, belongs to the Urban Bridge technical field.

Background technology

Along with developing of automobile industry, various vehicles also are more and more, and especially increasing of city private car caused huge pressure to urban traffic, and the simultaneous traffic accident also is on the increase, and have caused heavy losses for people's life and property.In order to alleviate traffic pressure, thoroughly solve owing to the many people of car these problems of the finding great trouble in getting to one's destination on foot that causes more, people are provided with many traffic lights in the crossroad, city, have small-sized overpass bridge toward contact.Mostly the small-sized overpass bridge of building is the pedestrian is shunted, the pedestrian can through overpass bridge arrive the direction highway section that will go, avoid the danger of jaywalk.Though and the setting of traffic lights has reduced the generation of traffic accident, craspedodrome or the motor vehicles that turn left and non power driven vehicle often will wait traffic signals and go, and the travel speed of vehicle is reduced greatly, and the utilization rate of urban road descends; Simultaneously non power driven vehicle is mixed in to go in the motor vehicles and usually can causes traffic jam, and therefore, the overpass bridge that sets up the vehicle mutually noninterfere that a kind of human and vehicle shunting and all directions go in the crossroad, city is our problem demanding prompt solution.

Summary of the invention

The purpose of the utility model is: provide simple in structure, take up an area of and lack, construction cost is low, to solve not crossroad, the city overpass bridge of smooth problem of city crossroad vehicle traffic.

The technical scheme of the utility model is:

Crossroad, a kind of city overpass bridge; It is made up of access bridge, tune rotating disk, craspedodrome left-hand rotation rotating disk, right-hand rotation ring road; It is characterized in that: the center, ground of crossroad is provided with the tune rotating disk through the internal layer column support of annular setting; Motorway is connected with the tune rotating disk through access bridge, and the outside of tune rotating disk is provided with craspedodrome left-hand rotation rotating disk through the outer column support of annular setting, and the ground between internal layer column and the outer column is provided with the non power driven vehicle rotary island; The tune rotating disk is connected through the right-hand rotation ring road with access bridge between the craspedodrome left-hand rotation rotating disk, is connected through up-run lane between craspedodrome left-hand rotation rotating disk and the right-hand rotation ring road, is connected through descending track between craspedodrome left-hand rotation rotating disk and the motorway.

Described access bridge and motorway junction be provided with the pedestrian's street crossing passage below ground.

The beneficial effect of the utility model is:

This crossroad, city overpass bridge is simple in structure, occupation of land is few; Can realize the purpose of reversing end for end, keeping straight on and turning left and turning right and go respectively through tune rotating disk, right-hand rotation ring road and craspedodrome left-hand rotation rotating disk, non power driven vehicle and pedestrian pass through with the realization of pedestrian's street crossing passage is without hindrance through the non power driven vehicle rotary island respectively; Improve the utilization rate of road, saved the time of waiting traffic signals, improved speed of a motor vehicle flow, reduced the probability of happening of traffic accident.

Description of drawings:

Accompanying drawing is the plan structure sketch map of crossroad, city overpass bridge.

Among the figure: 1, access bridge, 2, the tune rotating disk, 3, craspedodrome left-hand rotation rotating disk, 4, the right-hand rotation ring road; 5, internal layer column, 6, motorway, 7, outer column, 8, the non power driven vehicle rotary island; 9, nonmotorized vehicle lane, 10, the sidewalk, 11, up-run lane; 12, descending track, 13, the pedestrian's street crossing passage, 14, automobile.

The specific embodiment:

This crossroad, city overpass bridge is made up of access bridge 1, tune rotating disk 2, craspedodrome left-hand rotation rotating disk 3, right-hand rotation ring road 4; Tune rotating disk 2 has been set up through the internal layer column 5 of annular setting in the center, ground of crossroad; Motorway 6 is connected with tune rotating disk 2 through access bridge 1, access bridge 1 and motorway 6 junctions be provided with pedestrian's street crossing passage 13 below ground.

Craspedodrome left-hand rotation rotating disk 3 has been set up through the outer column 7 of annular setting in the outside of tune rotating disk 2, and the ground between internal layer column 5 and the outer column 7 is provided with non power driven vehicle rotary island 8; Non power driven vehicle rotary island 8 communicates with nonmotorized vehicle lane 9.Tune rotating disk 2 is connected through right-hand rotation ring road 4 with access bridge 1 between the craspedodrome left-hand rotation rotating disk 3, is connected through up-run lane 11 between craspedodrome left-hand rotation rotating disk 3 and the right-hand rotation ring road 4, is connected through descending track 12 between craspedodrome left-hand rotation rotating disk 3 and the motorway.

This crossroad, city overpass bridge can be realized motor vehicles tune, the purpose of keeping straight on and turning right and going respectively through tune rotating disk 2, right-hand rotation ring road 4 and craspedodrome left-hand rotation rotating disk 3, and non power driven vehicle and pedestrian realize without hindrance current through non power driven vehicle rotary island 8 and pedestrian's street crossing passage 13 respectively; With traveling automobile 14 from south to north is example: get into tune rotating disk 2 through access bridge 1 and can realize the purpose of reversing end for end to go, go but get into right-hand rotation ring road 4 right turns through access bridge 1.Sail right-hand rotation ring road 4 into by access bridge 1, get into craspedodrome left-hand rotation rotating disk 3, can realize respectively that through descending track 12 craspedodrome or left steering go then through up-run lane 11, and then the road of any one direction of arrival that can be safe and smooth.Equally, non power driven vehicle is advanced into non power driven vehicle rotary island 8 before nonmotorized vehicle lane 9, goes counter clockwise around non power driven vehicle rotary island 8, can arrive the nonmotorized vehicle lane 9 of purpose direction.The pedestrian 10 can turn right along the sidewalk, at most only need pass through two pedestrian's street crossing passages 13, can arrive the road of any one direction.

This crossroad, city overpass bridge is simple in structure, occupation of land is few, can thoroughly shunting between motor vehicles, non power driven vehicle and the pedestrian have been improved the utilization rate of road, has reduced the probability of happening of traffic accident.Be specially adapted to bustling crossroad, city and build use.
