Overhead day font overpass bridge

Technical field:

The utility model relates to a kind of new-type overpass bridge, belongs to the road and bridge technical field.

Background technology:

At present, overpass bridge is as a kind of effective ways that solve intersection different directions vehicular traffic conflict, and is widely-used.The pattern of overpass bridge is varied.Modal shown in Figure of description 1.This overpass bridge can be called single span formula overpass bridge.(1) is overhead single span crossbeam among the figure, and it is above the ground level, and across the track, north-south, links to each other with eastern access bridge (2), western access bridge (3), has guaranteed that the east-west direction vehicle is directly current.This overpass bridge is simple in structure, takes up an area of to lack, build easily, and no ring road, thereby be widely adopted.The shortcoming of this overpass bridge is: can't not having conflict and turn left, still is not a kind of intercommunicated overpass.Because the red and green signals lamp commander method that is still that bridge adopts down, so it occurs unimpeded and the phenomenon that the following pair arterial highway of bridge blocks up of major trunk roads on the bridge easily.Along with the continuous increase of vehicle flowrate, its limitation is more and more obvious.This is by the too little decision of its overhead part area.To its improved method is to increase the ring road of turning left, and classic methods is to adopt cloverleaf formula overpass bridge.But the method for turning left of cloverleaf formula overpass bridge is to turn right 270 °, and its ring road turning radius of turning left is bigger, and this just needs to remove building (4) among Fig. 1, and cost is high undoubtedly for this.Therefore, be necessary to design the overhead part area of a kind of increase, do not increase occupation of land, need not remove the surrounding buildings thing, do not increase the overpass bridge number of plies, the overpass bridge of the full intercommunication of all directions vehicle as far as possible.

Summary of the invention:

Content of the present utility model is shown in Figure of description 2.Its overhead part such as same " day " word.(1) is overhead single span crossbeam among the figure, is centre one horizontal stroke of " day " word, links to each other with ground by eastern access bridge (2), western access bridge (3), forms a single span formula overpass bridge, and this part is the same with Figure of description 1.Therefore, method that vehicle is kept straight on, turned right and East and West direction (major trunk roads) direction is reversed end for end and the single span formula overpass bridge shown in the accompanying drawing 1 are duplicate.(4) be core content of the present utility model, it is the frame of " day " word, and actual is a kind of ring road of turning left.It links to each other with track, ground, north-south by four access bridges (5), (6), (7), (8).Access bridge (5) claims to go down south access bridge, and the vehicle on the ring road of turning left (4) travels southwards by bridge under it.(6) access bridge that claims to go up north, northwards driving vehicle is up to the ring road of turning left (4) by it, turns left or reverses end for end.(7) claim south to go up access bridge, driving vehicle to the south is up to the ring road of turning left (4) by it, turns left or reverses end for end.(8) claim north access bridge down, the vehicle on the ring road of turning left (4) northwards travels by bridge under it.Like this, all vehicles can be by access bridge (3) or access bridge (2), (6), (7), sail the ring road of turning left (4) into, go in ring counterclockwise thereon, pass through access bridge (2) or access bridge (3), (5), (8) arrival target direction again, move thereby finish to turn left or reverse end for end.Like this, the craspedodrome of all vehicles, just turn right, turn left, reverse end for end to move and under the situation of not conflicting mutually, to carry out.Thereby can realize the purpose of full intercommunication.

The specific embodiment:

Embodiment one:

At first, Figure of description 2 is described in detail.For making drawing more directly perceived, adopt different grid line to represent different planes among the figure.This overpass bridge is actually the plane that height is erected " day " font, and by some access bridges it is connected with ground.(1) being overhead single span crossbeam, is centre one horizontal stroke of " day " word, links to each other with east-west direction track, ground by eastern access bridge (2), western access bridge (3), forms a single span formula overpass bridge, and this part is the same with Figure of description 1.(4) be core content of the present utility model, it is the frame of " day " word, and actual is a kind of ring road of turning left.It links to each other with track, ground, north-south by four access bridges (5), (6), (7), (8).(9) be the middle hard shoulder of north-south road, (10) are the segregator barriers in the middle of the East and West direction road.(11) be the track separator bar, all this dashed lines all are the track separator bars, and are simple and clear for drawing, only indicate this place.(12) be bicycle and sidewalk, what all this grid line were represented all is bicycle and sidewalk, simple and clear for drawing, only indicates this place.(13) be hard shoulder between motor vehicle and the bicycle, all this grid line are represented all is hard shoulder between motor vehicle and the bicycle, simple and clear for drawing, only indicates this place.(14) be bicycle and People's Bank of China's overpass, totally 4, at all directions of overpass bridge four ends, simple and clear respectively for drawing, only indicate this place.(17) be the access bridge of overpass, totally 16, each overpass (14) has four, and is simple and clear for drawing, draws two, only indicates this place.(15), (16) be the inlet of the underground passage of bicycle and walk, totally 4, simple and clear for drawing, only indicate this two place.(18) be geographical coordinate, indication all directions direction.

In the present embodiment, bicycle and pedestrian are current by underground passage.Because four underground passages are interconnected into a square, make bicycle and pedestrian craspedodrome, turn left, reverse end for end all to carry out underground, turn right and then carry out, so do not conflict fully with motor vehicle in the rightmost side on ground.

In the present embodiment, the passing method of

motor vehicle

3 and 2 is illustrated in conjunction with the accompanying drawings.For representing its passing method more intuitively, the method that accompanying drawing 3 adopts the method representation different directions vehicle of trailing Arabic numerals behind the arrows to go to different directions, arrow is represented direction of advance, Arabic numerals are represented different circuit sequence number (if behind the arrow two numerals are arranged, representing that these two lines merge at this).The passing method of its implication and whole overpass bridge is as shown in the table.

According to above method, vehicle can be realized full intercommunication under the situation of no traffic lights.

Because east-west direction is major trunk roads, generally be the municipal level highway, its width (comprising nonmotorized vehicle lane) is generally greater than 25 meters, thus the overall width of the overhead part of this overpass bridge also greater than 25 meters, it is complete passable that vehicle is reversed end for end thereon.Be necessary that two ends can be designed to semicircle.It is consistent with common rotary island that vehicle moves principle thereon.

Embodiment two:

Present embodiment and embodiment one basically identical.Difference is to replace the tunnel, street with four People's Bank of China's overpasses (14).Shortcoming is that pedestrian and non motorized vehicle is crossed the street stretch that will detour, and advantage is to build easily.

Embodiment three:

Present embodiment is a kind of simplified embodiment, and purpose is to remove overpass (14) and underground passage (15), (16).This is that bicycle is as a kind of vehicles of environmental protection because of the enhancing along with people's environmental protection concept, rises again in its status.And above-mentioned two kinds of embodiment bicycles and pedestrian's street crossing are all inconvenient, and for this reason, structure of this overpass bridge and passing method also will change slightly.Basic ideas are to reach vehicle current on the ring road on the bridge, and its passing method is not changed; And reactivate traffic lights under the bridge, shown in Figure of description 4.This figure is a current principle vertical view under the present embodiment bridge.Among the figure, the implication of the object of each lead-in wire expression is the same with accompanying drawing 2, and just hard shoulder (9) in the middle of the road of north-south and the hard shoulder (13) between motor vehicle and the bicycle will be opened some breach, pass through for bicycle and pedestrian, simultaneously, remove overpass and underground passage.This is the variation of doing on the overpass bridge structure.

In the accompanying drawing 4, still represent the method that the different directions vehicle goes to different directions with the circuit sequence number.3, the meaning represented of 4, No. 5 circuits is the same with embodiment one.No. 0 line is the line of being turned right by south east.No. 8 line is by north orientation south direct-through line, and No. 9 line is the line of being turned right by north west.In fact, except that the tune of thing end, just four turn right line and north-south direct-through lines that bridge is current down.If the pedestrian is gone to the C place by A, he and 3,9 two line conflicts of turning right.If the pedestrian is gone to the B place by A, he and 3,5,8,0 four circuit conflicts.Other B, C, 3 situations of D are similar to A.

For solving these conflicts, can freeze the motion of all motor vehicles under the bridge with red light simultaneously, be bicycle and walk time this moment.So just solved above-mentioned conflict with the simplest method.

The advantage of this embodiment is to have removed overpass or underground passage, has simplified the overpass bridge structure; Bicycle and pedestrian are current, more convenient on ground.Shortcoming is current under the bridge four lines and two north-south direct-through lines are current will pause to some extent of turning right.

Embodiment four:

Present embodiment also is a kind of simplified embodiment, and purpose is only to move dilly on the ring road of turning left (4) and its four access bridges (5), (6), (7), (8), thereby reduces this overpass bridge cost greatly.This is that turning radius is little because the dilly climbing capacity is strong, to bridge load require low, change lane is fast, can lower the requirement greatly aspect bridge pier and beam strength, the gradient, the width to the bridge of its operation design.Like this, operation rule of this overpass bridge and structure will be done some changes.Its structural change is the same with embodiment three, and current principle main points are: still use traffic lights under the bridge; Except that east-west direction was straight-through, other all direction oversize vehicles (as bus) can only move under bridge; All direction dillies are only turned right under bridge; Keep straight on, turn left, reverse end for end to go up bridge.By this principle, bridge is current down mainly is exactly bus and pedestrian, bicycle.This equals to have become under the bridge " dedicated bus lines ".Still commanded by conventional method by traffic lights though it passes through, passage rate still can improve greatly.The advantage of this embodiment is to have removed overpass or underground passage, has simplified the overpass bridge structure; Bicycle and pedestrian are current, more convenient on ground.Dilly has been diverted on the bridge and (has removed and turn right), has split dedicated bus lines.On the ring road of turning left (4) and its four access bridges (5), (6), (7), (8), only move dilly, reduce the overpass bridge cost greatly, be fit to very much existing single span formula overpass bridge is transformed.Shortcoming is that vehicle current under the bridge will pause to some extent.

Embodiment five:

Present embodiment is that the structure of the ring road of turning left is done a variation, its two ends perk.As shown in Figure 5.The purpose of making is to reduce to turn left the length of ring road (4) like this, promptly " day " word become more flat.This is will pass under the ring road of turning left (4) two ends because of the vehicle on access bridge (2), (3), its two ends perk, and length just can be shorter.Shortcoming is that the ring road (4) of turning left is gone up vehicle operating and wanted climb and fall.Good effect:

The utility model has the advantages that:

1, occupation of land is little: this overpass bridge takes up an area of the same substantially with the occupation of land of traditional single span formula overpass bridge, and this is very important for crowded urban traffic space.

2, the traffic capacity is big: this overpass bridge traffic capacity is the same with classical cloverleaf formula overpass bridge basically.

3, simple in structure, construction cost is low, and passing method is versatile and flexible, promptly can be used for traditional single span formula overpass bridge is transformed, and can be used for newly-built overpass bridge again.
