The combined bridge of the two right-turning and straight-going Y-shaped bifurcation bridges has the advantages that a problem that straight-going motor vehicles and right-turning vehicles of two opposite ground branch roads at the crossroads cross and occupy the roads is resolved, hazard degree of local geological changes caused to the whole combined bridge is reduced, and the right-turning bridge can serve as a right-turning and left-turning shared bridge, accordingly vehicles can directly turn right without unnecessary bypassing.

Description

Two composite bridges of turning right and keeping straight on " Y " font bifurcated bridge
Technical field
The utility model belongs to the overpass bridge that makes the right-angled intersection automobile traffic, particularly two independently the Y-shaped arch bridge be combined into the craspedodrome motor vehicle that can make the crossroad opposite face (hereinafter to be referred as: straightgoing vehicle) and the right-hand bend motor vehicle (hereinafter to be referred as the have no road occupying composite bridge of the conflict right-hand bend car).
Background technology
At present, the traffic of international and domestic usual friendship crossroad, arterial street is very crowded, often stops up, and is each metropolitan common fault of the whole world.Tracing it to its cause, is because the two road usual friendship, and on the crosspoint, two road are overlapping to have become a road, and the motor vehicles on the two road can only a shared road on node, has lost the path resource of half.Add pedestrian, bicycle and motor vehicle and mix row, the result that is inevitable blocks up.In order to solve this difficult problem, people have expected widening the road surface, increase the quantity of crossing runway, but the road surface can not be widened infinitely.People have expected overpass bridge again, but in existing upright civilian bridge design scheme, can make crossroad direct lane and right-turn lane have no road occupying the conflict the overpass bridge minimum diameter more than 120 meters, not only build the cost height, and the crossroad of the two-way six-lane in old urban area all can not be built, make the crossroad traffic congestion of present old urban area very serious, the frequent traffic paralysis in the crossroad that has.
Chinese patent 200720043390.6 " the full-overpass bridge of individual layer " discloses a kind of combining structure associating bridge of directly striding a bridge and an annular bridge of establishing at the parting of the ways.Its shortcoming: the driver must see clearly operation sign at the parting of the ways, in case can not lane change after not seeing clearly or seeing clearly, can cause promptly advancing the traffic congestion of place, crossroad in the lane change crosspoint.This overpass bridge can not be used on the road of existing standard.
Chinese patent 200820230509.5 is " directly right, the left-hand rotation interchange overpass " a kind of overpass bridge disclosed, because the claims and the manual of this patent are very unclear to the description of technical scheme, but as if just structure and the defective that can understand this screen frame shape overpass bridge with Figure of description is: one, unwanted height and length have been increased: in by-path position, ground away from the crossroad, continuing one section pontic after the craspedodrome bridge passes below the right-hand bend bridge on opposite more just is connected with ground, make the overhead highly very high of upper layer bridge, increased the total length of bridge, make whole pontic not only high not only long but also big like this, waste bridge construction expense has been blocked civic landscape.Two, local damage causes whole the damage: after the right-hand bend bridge passes below the craspedodrome bridge of ground, right side by-path and right-hand bend bridge, with be connected with ground again after the lower bridge section of the craspedodrome bridge of ground, left side by-path flushes, also make the overhead highly very high of upper layer bridge, increased the total length of bridge, also make whole pontics be connected to a large-scale integral bridge, once the part of this large-scale integral bridge has geology to change, its part is damaged and just will causes whole large-scale integral bridges to damage.Three, whole bridge becomes screen frame shape area occupied too big: the global shape of overpass bridge is for there being two cornerwise screen frame shape pontics, requiring the crossroad not have the circular minimum diameter in vacant lot of building is 115 meters, and in the two-way six-lane crossroad of old urban area, diameter reaches 115 meters almost not having, just the overpass bridge that provides of this Figure of description almost can not be used for two-way six-lane crossroad, old urban area, even right-hand bend bridge and left-hand bend bridge inwardly are recessed to minimum half through having only 15.0 meters, the minimum diameter of whole screen frame shape overpass bridge also causes wants 75.0 meters less.
Summary of the invention
The purpose of this utility model provides the road track that meets existing left lateral system traffic specification and arranges, small size crossroad at two-way six-lane can be built, and two " Y " font bifurcated bridges are combined into have no road occupying two bridge modular bridges of conflict of the direct lane that props up on opposite face ground and right-turn lane.
The design that the utility model solves intersection road occupying conflict point is: at the parting of the ways, there is the road occupying of intersection conflict direct lane that prop up on opposite face ground and right-turn lane, and the right-hand bend car of opposite face ground by-path can not pass through when promptly straightgoing vehicle was current.But the not shared bridge floor that two craspedodrome bridges will keeping straight on relatively are separate, make a craspedodrome bridge after striding across the crossroad, pass under the right-hand bend bridge of " Y " font Y-shaped arch bridge on opposite through ground, just stride across under the craspedodrome bridge of crossroad the bridge joint place and more approach the right-angled intersection center, and the last bridge point of opposite craspedodrome bridge is further from the center, crossroad, distance between the last bridge joint place of two craspedodrome bridges of opposite face and the following bridge joint place, just climbing as opposite right-hand bend bridge can multilevel traffic needs right-hand bend bridge climbing length highly.Just straight bridge earth terminal if before near the zone, high position, stage casing of opposite craspedodrome arch bridge ground plane, just abdicate the superjacent air space on right side for opposite craspedodrome arch bridge, promptly allow the right-hand bend bridge on opposite directly go out right curved bridge single file section, the multilevel traffic in addition the ground by-path at the parting of the ways of the right-hand bend bridge of realizing craspedodrome arch bridge and opposite at the side bifurcated of turning right.Like this, as long as the right-hand bend bridge is the height of one deck bridge, and all composite bridge all has only the height of one deck bridge, saves the bridge construction expense, and little to the civic landscape influence, many tracks leaving the crossroad merge the track and are difficult for traffic congestion on ground.
Structure of the present utility model is:
Two composite bridges of turning right and keeping straight on " Y " font bifurcated bridge, comprise two Y-shaped arch bridges, it is characterized in that: each Y-shaped arch bridge all has a craspedodrome arch bridge 2 and a right-hand bend bridge 3, right-hand bend bridge 3 is positioned at the right side of craspedodrome arch bridge 2, right-hand bend bridge 3 is all at a side and craspedodrome arch bridge 2 bifurcateds of turning right, this bifurcation is a bifurcation 15, make a craspedodrome arch bridge 2 and a right-hand bend bridge 3 form " Y " font bifurcated bridge, then two Y-shaped arch bridges become two bifurcated " Y " font fork bridges 1 in the same way;

Advantage of the present utility model:
One, can solve through vehicles on two ground by-paths of crossroad opposite face and the right-hand bend vehicle problem that has no road occupying, also solve through vehicles and right-hand bend vehicle on these two ground by-paths, with through vehicles in addition two ground by-paths of crossroad and the right-hand bend vehicle problem that has no road occupying; It is too little to be specially adapted to the crossroad area, and the place that can not all repair overpass bridge on four ground by-paths solves nearly 70% traffic jam amount.Only surplus do not have craspedodrome and right-hand bend vehicle crisscross traffic such a case of two ground by-paths of opposite face of overpass bridge to need traffic lights to direct traffic.If do not establish the right-hand bend bridge respectively on this has two ground by-paths of opposite face of overpass bridge, whole craspedodromes of its crossroad and right-hand bend vehicle are realized having no road occupying.
Two, large-scale overpass bridge is divided into two small-sized " Y " font overpass bridges, reduce the disaster that geology changes: the disclosed screen frame shape of the Figure of description overpass bridge of Chinese patent 200820230509.5 " directly right, left-hand rotation interchange overpass " is the large-scale screen frame formula of an integral body overpass bridge that is connected as a single entity, total length is very long, floor space is very big, when in total length and floor space, there being geology to change, cause whole large-scale overpass bridge not use, this crossroad access is paralysed fully.And the utility model above-mentioned whole large-scale screen frame formula overpass bridge is split as bifurcated in the same way " Y " the font fork bridge that two independences are not connected is small-sized overpass bridge, finish the right-hand rotation and the craspedodrome grade separation function of two ground by-paths of crossroad opposite face respectively with these two small-sized overpass bridges, and can also with the right-hand rotation car and the straightgoing vehicle grade separation of two other ground by-path, in identical driving speed per hour, under the identical technical data conditions such as the pontic gradient, compare the large-scale screen frame overpass bridge of Chinese patent 200820230509.5 Figure of description, each small-sized overpass bridge of the present utility model shortens 30-35% than the total length of present large-scale overpass bridge, and two small-sized overpass bridges take up an area of the gross area and reduce 70-80%; In a word, the utility model than existing large-scale overpass bridge, greatly reduces the risk of geological disaster with small-sized overpass bridge.
Three, be same as the former circuit of plane traffic and do not have unnecessary detouring: the straightgoing vehicle and the right-hand bend car of two-way six-lane crossroad opposite face are had no road occupying, right-hand bend car no unnecessary the detouring of directly turning right, also not with another ground by-path of crossroad on vehicle have the road occupying of intersection to conflict.The engineering quantity of building bridge in addition is less than, and saves the bridge construction engineering cost.
Four, the little crossroad of two-way six-lane can be used: the utility model is only used two combinations of " Y " font Y-shaped arch bridge in the same way, reduced the length of bridge in a large number than the existing intercommunicated overpass that detours, reduced floor space and space in a large number, made it have only 45.0 meters two-way six-lane small size crossroad, city also can realize most of vehicle grade separation at round diameter.
Five, one deck bridge is only used in the multilevel traffic of through vehicles and right-hand rotation vehicle: all composite bridge is all only used one deck overpass bridge.Littler to the civic landscape influence.
Inventive point of the present utility model is:
One, the last bridge joint place of craspedodrome bridge misplaces with the front and back, following bridge joint place of another craspedodrome bridge: the not shared bridge floor of two craspedodrome bridges of the relative craspedodrome in crossroad, but it is separate, dislocation before and after the following bridge joint place of the last bridge joint place of a craspedodrome bridge and another craspedodrome bridge has, but the distance of dislocation is exactly the highly needed climbing length of straightgoing vehicle multilevel traffic that bridge will climb and can come with the opposite of turning right.Bifurcated in the same way " Y " the fonts fork bridges that two branch prongs are relative are formed composite bridges, two in the same way bifurcated " Y " font fork bridge is separate is not connected, but their straight bridge single file section part sections extend into the opposite in the same way in the branch prong of bifurcated " Y " font fork bridge.
Two, the pontic of craspedodrome bridge and opposite right-hand bend bridge does not pass through mutually: this craspedodrome bridge does not pass, does not stride across the right-hand bend bridge on opposite, the right-hand bend bridge realization craspedodrome that just makes the vehicle on the craspedodrome bridge pass the opposite from ground.This structure makes by the multichannel vehicle behind the crossroad and realizes that on ground merging the track leaves the crossroad, as long as merge the merging track section that just can there be longer distance in the track on ground, be difficult for because of merging too little too narrow traffic congestion of track point, the disclosed screen frame shape of the Figure of description overpass bridge that has overcome Chinese patent 200820230509.5 " directly right, left-hand rotation interchange overpass " merges too narrow very little and the problem that easy generation is blocked up of track point on overpass bridge.
Three, traffic conflict point is moved on to away from the by-path position, ground of crossroad go multilevel traffic: the utility model is not the position that the road occupying conflict takes place to intersect at the plane traffic behavior, i.e. not interior position solution direct lane and the right-turn lane intersection road occupying conflict of scope at the parting of the ways, but creationary this class traffic conflict point move on to away from four ground by-paths of crossroad with the conflict of three-dimensional bridge transport solution, thereby can take minimumly the ground and the space of crossroad.As long as composite bridge of the present utility model just can be built up in the ground of crossroad diameter more than 45.0 meters, realize that old city has the crossroad access of six-lane to improve greatly, stop up the meaning that initiative is arranged for solving the little crossroad access in old urban area.
Four, on the by-path of the ground on two opposites, the ground of craspedodrome bridge prolongs the right-hand bend bridge of wearing the opposite under the track: keeping straight on relatively is two two-way craspedodrome arch bridges that rightabout is kept straight on, separate, not shared bridge; Be straight bridge earth terminal than the opposite in the same way the common bridge earth terminal that rises of bifurcated " Y " font fork bridge more near the center, crossroad; Straight bridge earth terminal is near opposite ground connection before the zone, high position of bifurcated " Y " font fork bridge in the same way, so straight bridge earth terminal has been reserved the space, high position of bifurcated " Y " font fork bridge in the same way, opposite, allow the curved bridge single file section in the right side on opposite can be directly at the craspedodrome arch bridge bifurcated on right-hand bend one side and opposite, two bridge bifurcateds can directly be turned right the right-hand bend vehicle and are not needed unnecessary detouring, the vehicle that leaves straight bridge earth terminal can be passed from the turn right ground, bifurcated section below of bridge of opposite face, realize the multilevel traffic of through vehicles and opposite right-hand bend vehicle.
