The combined type means of transportation in right lateral system " fore-telling " font bifurcated bridge and bifurcated tunnel

Technical field

The utility model belongs to the means of transportation that make the right-angled intersection automobile traffic unimpeded, particularly two independently Y-shaped arch bridge and two independently the bifurcated tunnel be combined into the craspedodrome motor vehicle that can make the crossroad (hereinafter to be referred as: straightgoing vehicle) and the left-hand bend motor vehicle (hereinafter to be referred as the have no road occupying facility that has a good transport and communication network of conflict left turning vehicle).

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 left 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 unblocked overpass bridge of individual layer " discloses a kind of unimpeded 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.----the road division standard of turning right is different from the road of existing left-hand rotation--craspedodrome---right-hand rotation and divides standard, and this has had little time lane change after making the driver near this overpass bridge in left-hand rotation in craspedodrome from inside to outside.In a word,----the road division standard of turning right is different from the road that has--craspedodrome---right-hand rotation now and divides standard, and this overpass bridge can not be used on the road that has standard now in left-hand rotation in the craspedodrome from inside to outside that this overpass bridge requires.

Chinese patent 200820230509.5 is " directly left, the right-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 left-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 left-hand bend bridge passes below the craspedodrome bridge of ground, left side by-path and left-hand bend bridge, with be connected with ground again after the lower bridge section of the craspedodrome bridge of ground, right 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, the requirement crossroad does not have 115.0 meters of the circular minimum diameters in the vacant lot of building, and in the two-way six-lane crossroad of old urban area, diameter reaches 115 meters almost not having, and 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.

Summary of the invention

The purpose of this utility model provides the road track that meets existing right lateral system traffic specification and arranges, small size crossroad at two-way six-lane can be built, two " fore-telling " font bifurcated bridges and two " fore-telling " font bifurcated tunnels are combined at the parting of the ways, the conflict that has no road occupying of direct lane and left turn lane, do not have the section of interweaving, and a plurality of tracks of leaving the crossroad there is long merging track section and two bridges that are difficult for traffic congestion add two tunnel combined type means of transportation.

The utility model solve to intersect the design of road occupying conflict point and is: a plurality of conflict points of right-angled intersection plane traffic are divided into three kinds of conflict points: first kind is that the left turn lane on direct lane and opposite has the road occupying conflict; Second kind be four direct lanes be divided into two groups at the parting of the ways the central area have and intersect the road occupying conflict; The third is that the left turn lane has the road occupying of intersection to conflict with direct lane and the left turn lane that this left turn lane arrives the ground by-path.

Solve first kind, there is the technical scheme of road occupying conflict the left turn lane on direct lane and opposite: craspedodrome bridge and left-hand bend bridge on two ground by-paths of right-angled intersection opposite face are one group, and every group last bridge end all is connected with same ground by-path.Two craspedodrome bridges of keeping straight on are separate relatively, make a craspedodrome bridge after striding across right-angled intersection, pass under the left-hand bend bridge of " fore-telling " font Y-shaped arch bridge on opposite through ground, solved direct lane and opposite the left turn lane intersect collision problem.Craspedodrome tunnel and left-hand bend tunnel under two ground by-paths of another group opposite face of right-angled intersection are one group, and every group the tunnel end that advances all is connected with same ground by-path.Two craspedodrome tunnels of keeping straight on are separate relatively, make a craspedodrome tunnel after passing right-angled intersection, stride across above the left-hand bend tunnel in " fore-telling " font bifurcated tunnel to ground from the opposite on the vehicle, solved craspedodrome tunnel and opposite the left-hand bend tunnel intersect collision problem.This technical scheme has solved four road occupying conflict points.

Solve second kind, article four, direct lane be divided into two groups at the parting of the ways the central area have and intersect the technical scheme of road occupying conflict: one group of four direct lane travelling of intersecting are current respectively on the ground two the underground independently craspedodrome tunnel of bridges and another group of independently keeping straight on, become multilevel traffic, solved four direct lanes traffic conflict problem of central area at the parting of the ways.This technical scheme has solved four road occupying conflict points.

Solve the third, to be the left turn lane with the direct lane of arrival ground by-path and left turn lane have intersects the technical scheme that road occupying conflicts: from the vehicle to the by-path of ground, left side under the earth terminal of left-hand bend bridge, on stride craspedodrome tunnel and left-hand bend tunnel below the by-path of ground, left side; In like manner wear the craspedodrome bridge and the left-hand bend bridge of by-path top, ground, left side under the vehicle to the by-path of ground, left side on the earth terminal in left-hand bend tunnel.Solved the collision problem that intersects of the direct lane of left turn lane and the ground by-path of arrival and left turn lane.This technical scheme has solved eight road occupying conflict points.

Like this, 16 road occupying conflict points of plane traffic cross-road have been realized multilevel traffic fully, no longer include the road occupying conflict point between the rolling stock.

The design of the new function of the utility model: take ground and space for reduce the utility model combined facility as far as possible, traffic route fully can be identical the left turn lane and the right-turn lane of ground, left side, this left turn lane by-path, the width that the left and right merging bridge or the tunnel that travel with an energy rightabout, left and right commentaries on classics merge bridge or tunnel can reduce width about 5.0 meters than the overall width in side by side two independent left-hand bend bridges or tunnel and right-hand bend bridge or tunnel.So, the mode that the utility model is two independent bridges without the disclosed left and right commentaries on classics of Figure of description of Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass " reaches and reduces the purpose that combined facility takies ground and space but become left-hand bend bridge or Tunnel Design left and right commentaries on classics to merge bridge or tunnel.

For having geology in the pontic position, the large-scale overpass bridge of avoiding Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass " accompanying drawing to provide changes, to the destruction of a part of pontic and the destruction that causes whole pontic, also avoid large-scale overpass bridge can not be used for the problem of the small-sized crossroad of two-way six-lane, old urban area, this large-scale overpass bridge that can not be connected is divided into two small-sized bifurcated in the same way " fore-telling " font fork bridges, with two small-sized bifurcated in the same way " fore-telling " font fork tunnels, on the ground with underground current respectively.And also give bicycle and pedestrian ground in the road.

The driving route that the utility model not only will solve the crossroad does not have the intersection collision problem, and also being provided at has sufficiently long merging track section on the ground level road that leaves the crossroad, solves the merging track and only has only a point and produce the problem of traffic congestion on bridge.The through vehicles of crossroad and left-hand bend vehicle not only will accomplish not have the road occupying conflict point, will accomplish that also the through vehicles, left-hand bend vehicle, right-hand bend vehicle from the Different Ground by-path has the merging track of a plurality of merging track points section leaving on the by-path of ground, crossroad.The utility model is located at ground merging the track section, though merge the track section is the rule that ground level road is divided, the structure content that does not belong to the utility model overpass bridge, but the structure of the utility model grade separation facility can make the ground by-path can obtain to merge the track section.And a plurality of pontics that the disclosed screen frame shape of the Figure of description overpass bridge of Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass " can be regarded as after leaving cross friendship center merge the track at a point, make through vehicles, left-hand bend vehicle and right-hand bend vehicle on bridge, have only one to merge the track point, this three tracks merge track point, the very easy consequence that blocks up that causes with one together on bridge on overpass bridge.And the utility model carries out the track merging with the merging track section that can be provided at the ground certain-length, can solve from the vehicle on the different pontics because of merging the too narrow very little traffic congestion problem that produces of track point.So, through vehicles and left-hand bend vehicle that the utility model not only can solve each bar ground by-path of crossroad have no road occupying unimpeded, can also solve when on a ground by-path, leaving the crossroad from the vehicle on the Different Ground by-path, very well-to-do ground is arranged as merging the track section, the disclosed screen frame shape of the Figure of description overpass bridge of comparing Chinese patent 200820230509.5 has only a position to merge the track, and then the utility model can reduce at double because of merging the too narrow very little traffic congestion problem that produces of track point.

Craspedodrome arch bridge 2 is the current bridges of two ground by-paths that are used for the crossroad opposite face, craspedodrome tunnel 22 is the current tunnels of two ground by-paths that are used for the crossroad opposite face, " craspedodrome " is meant that motor vehicles arrive the meaning of opposite, crossroad road, " craspedodrome " is not meant shape, and is meant purposes.

Left-hand bend bridge 3 is the left-hand bend bridges that are used for crossroad right-hand traffic system, and " left-hand bend " is that purposes is the meaning of turning left.Left-hand bend tunnel 23 is the left-hand bend tunnels that are used for crossroad right-hand traffic system, and " left-hand bend " is that purposes is the meaning of turning left.

The bifurcated section 7 of left-hand bend bridge 3 is the bridge sections that are used for passing from ground from the motor vehicles of the craspedodrome arch bridge 2 on opposite current usefulness, there are motor vehicles to pass the height of needs below the height of bifurcated section 7 need satisfy, are preferably in zone, the high position bifurcated that satisfies traffic specification with craspedodrome arch bridge 2 so the left-hand bend bridge 3 of bridge 1 pitched in same bifurcated in the same way " fore-telling " font.The bifurcated section 27 in left-hand bend tunnel 23 is the tunnel construction sections that are used for striding across from ground from the motor vehicles in the craspedodrome tunnel 22 on opposite current usefulness, the degree of depth that the current needs of motor vehicles are arranged above the degree of depth of bifurcated section 27 need satisfy is put regional bifurcated so the left-hand bend tunnel 23 in same bifurcated in the same way " fore-telling " font fork tunnel 21 is preferably in the deep-seated that satisfies traffic specification with craspedodrome tunnel 22.

Left-hand rotation bridge earth terminal 6 preferably is positioned near the ground the bifurcation 35 in bifurcated in the same way " fore-telling " font fork tunnel 21 of the ground by-path that will arrive near left-hand bend, the curved bridge single file section 13 in a left side does not stride across bifurcated in the same way " fore-tellings " the font fork tunnel 21 of the ground by-path that left-hand bend will arrive, and pitches tunnel 21 so that the left-hand bend motor vehicles stride across bifurcated in the same way " fore-telling " font of the ground by-path that is arrived from ground.The left-hand bend motor vehicles are gone up the through vehicles merging track of arriving ground in bifurcated " fore-telling " the font fork 21 craspedodrome tunnels 22, tunnel in the same way on ground and right side, long ground, merging track section can be arranged, rather than have only one to merge the track point.Avoided the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge, make the through vehicles on left-hand bend vehicle and ground, the right side by-path merge the track, be easy to generate the problem of traffic congestion but the merging track point on bridge is too narrow very little in the pontic position of two bridges.

Left-hand rotation tunnel earth terminal 26 preferably is positioned near the ground the bifurcation 15 of bifurcated in the same way " fore-telling " font fork bridge 1 of the ground by-path that will arrive near left-hand bend, curved tunnel, left side single file section 33 is not passed bifurcated in the same way " fore-tellings " the font fork bridge 1 of the ground by-path that left-hand bend will arrive, and pitches bridge 1 so that the left-hand bend motor vehicles pass bifurcated in the same way " fore-telling " font of the ground by-path that is arrived from ground.The left-hand bend motor vehicles on ground and right side in the same way 2 times through vehicles of bifurcated " fore-telling " font fork bridge 1 craspedodrome arch bridge to ground merge tracks, long ground, merging track section can be arranged, rather than have only one to merge the track point.It is too narrow very little and be easy to generate the problem of traffic congestion to have avoided merging track point.

The stage casing of bifurcated " fore-telling " font fork bridge 1 is provided with the zone, high position in the same way, so that from the right side in the same way the left-hand bend vehicle in bifurcated " fore-telling " font fork tunnel 21 below it, pass behind ground from left-hand rotation tunnel earth terminal 26, thereby realize this bifurcated " fore-tellings " font fork bridge 1 and left-hand bend vehicle energy multilevel traffic in the same way from the right side.The stage casing in bifurcated " fore-telling " font fork tunnel 21 is provided with deep-seated and puts the zone in the same way, so that from the right side in the same way the left-hand bend vehicle of bifurcated " fore-telling " font fork bridge 1 from left-hand rotation bridge earth terminal 6 to ground after from it face stride across, thereby realize this bifurcated " fore-tellings " font fork tunnel 21 and left-hand bend vehicle energy multilevel traffic in the same way from the right side.

Grouping bridge is by minute prong relative two combining structure of bifurcated " fore-telling " font fork bridge 1 in the same way, and the straightgoing vehicle that travels as the rightabout of two ground by-paths of crossroad opposite face realizes keeping straight on and left turning vehicle is realized the composite bridge of left-hand bend.The grouping tunnel is by minute prong relative two combining structure in bifurcated " fore-tellings " font fork tunnel 21 in the same way, and the straightgoing vehicle that travels as the rightabout of two ground by-paths of crossroad opposite face is realized keeping straight on and left turning vehicle is realized the combination tunnel of left-hand bend.A crossroad needs the straight bridge single file section 8 of a grouping bridge and 28 one-tenth three-dimensional decussate textures of straight tunnel single file section in a grouping tunnel.

" cross " meaning of straight bridge single file section 8 and straight 28 one-tenth three-dimensional decussate textures of tunnel single file section does not limit and is an angle of 90 degrees intersection mutually, here " cross " is identical with " cross " implication of crossroad, promptly there is intersection in two roads of " cross " general reference, do not limit intersecting angle.So, if straight bridge single file section 8 and straight tunnel single file section 28 have bending also still to be considered as decussate texture.The shape of stereo cross shape structure is meant above decussate texture overlooks, straight bridge single file section 8 and straight 28 one-tenth three-dimensional decussate textures of tunnel single file section, but straight bridge single file section 8 is not connected with straight tunnel single file section 28, space length is up and down arranged, and it is current to satisfy motor vehicles.

The optimum position of straight bridge earth terminal 5: the straight bridge earth terminal 5 of two embedded grouping bridges near the opposite in the same way bifurcated " fore-tellings " font pitch the bifurcated section 7 below ground locations of bridge 1.As long as make its through vehicles pass bifurcated section 7 from ground, then the height of bifurcated section 7 can reduce as far as possible, promptly the height of one deck bridge.The optimum position of straight tunnel earth terminal 25: the straight tunnel earth terminal 25 in two embedded groupings tunnel near the opposite in the same way bifurcated " fore-tellings " font pitch the bifurcated section 27 top ground locations in tunnel 21.Make its through vehicles stride across bifurcated section 27 from ground, then the degree of depth of bifurcated section 27 can reduce as far as possible.

The preferred structure of left-hand bend bridge 3: the curved bridge single file section 13 in the left side of left-hand bend bridge 3 is preferably to the arcuate structure of 28 one-tenth three-dimensional decussate textures of two straight bridge single file sections 8 and two straight tunnel single file sections central area indent.The preferred structure in left-hand bend tunnel 23: curved tunnel, the left side in left-hand bend tunnel 23 single file section 33 is preferably to the arcuate structure of 8 one-tenth three-dimensional decussate textures of two straight tunnel single file sections 28 and two straight bridge single file sections central area indent.In order to prolong the length of curved bridge single file section 13 in a left side and curved tunnel, left side single file section 33, meet the traffic specification requirement and satisfy the gradient, and take ground, crossroad, space, underground position less as far as possible, and the arcuate structure that the turn fractions of curved bridge single file section 13 in a left side and curved tunnel, left side single file section 33 is arranged to concave.This preferred structure makes the utility model can be used for having only more than 55 meters between place, diagonal angle, the crossroad building, and the small-sized crossroad of two-way six-lane, can both build the unimpeded facility of combination of the present utility model.This just makes the utility model can be used for the crossroad, arterial highway in old city, realizes that old arterial street crossroad straightgoing vehicle and left-hand rotation car that people wish have no road occupying unimpeded.

The curved tunnel of a curved bridge single file section 13 in a left side and left side single file section 33 min. turning radius of arc of concaving design: the central point with 28 one-tenth three-dimensional decussate textures of two straight bridge single file sections 8 and two straight tunnel single file sections is the center, the curved bridge single file section 13 in a left side is the arcs to stereo cross shape structure centre indent, and curved tunnel, left side single file section 33 is the arcs to stereo cross shape structure centre indent; The beeline length of curved bridge single file section 13 in a relative left side and curved tunnel, left side single file section 33 is L, the min. turning radius of the curved tunnel of a curved bridge single file section 13 in an arc left side or arc left side single file section 33 is R, in the scope of 30.0 meters≤L≤80.0 meter, the relationship of L and R is: R=L ÷ 4+8.When L=60.0 rice, R=23.0 rice.L is long more, illustrates that the crossroad area is big more, and then turning radius R can be big more, and the curved tunnel of a curved bridge single file section 13 in an arc left side and arc left side single file section 33 can be born the fast more travel speed of motor vehicle.

At the parting of the ways, because there is not intersection road occupying collision problem between the motor vehicles in the right-hand bend of right lateral system, not the subject matter that this patent will solve so turn right.Turning right from ground can be without overpass bridge and tunnel, but will have the road occupying of intersection to conflict with bicycle and pedestrian.For avoiding this intersection road occupying conflict, the outside in left-hand bend bridge 3 and left-hand bend tunnel 23 promptly can be widened in the left side, the right-hand bend car that is used for ground, left side by-path uses, and just turn left bridge 3 and left-hand bend tunnel 23 become the left turning vehicle of this ground by-path and the common combined bridge or the tunnel that uses of right-hand bend car of ground, left side by-path.The structure in left-hand bend bridge 3 and left-hand bend tunnel 23 is without any variation, just become left and right commentaries on classics combined bridge or the dual-purpose tunnel of left and right commentaries on classics, it is unimpeded fully to make the utility model become four craspedodrome roads of crossroad, four left-turning pathways, four right-hand rotation bends, the full intercommunication combined type means of transportation of neither one intersection road occupying conflict point have promptly been realized the full intercommunication multilevel traffic facility that whole tracks, crossroad are unimpeded.But the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge will reach the unimpeded multilevel traffic in whole tracks, crossroad, is provided with the right-hand bend service bridge, and promptly turn right bridge and left-hand bend bridge are two graded crossing bridges side by side.According to overpass bridge and Tunnel Design standard, the minimum widith in left and right commentaries on classics combined bridge of the present utility model or tunnel can be 10.0 meters, but the right-hand bend bridge of the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge and left-hand bend bridge minimum widith side by side are 15.0 meters.Consequently, the left and right commentaries on classics of one-sided realization, the utility model has reduced by 5.0 meters occupation of land width; Only this has reduced by 10.0 meters occupation of land face width degree with regard to one than the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge.This stand out of 10.0 meters, make combined type means of transportation of the present utility model can be used for the almost crossroad of any two-way six-lane, and have the crossroad of a lot of two-way six-lanes all can not use the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge.That is to say, make combined type means of transportation of the present utility model usability widely be arranged than the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge, combined type means of transportation of the present utility model can be solved outside any problem of the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge, can also solve the multilevel traffic problem of the indeterminable littler crossroad of Chinese patent 200820230509.5 Figure of description disclosed screen frame shape overpass bridge.

Advantage of the present utility model:

One, large communications facility is divided into the combination of four small-sized means of transportation, reduce the disaster degree that geology changes: the disclosed screen frame shape of the Figure of description overpass bridge of Chinese patent 200820230509.5 " direct left and right commentaries on classics 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, will produce this overpass bridge and destroy, cause whole large-scale overpass bridge not use, this crossroad access is paralysed fully.And the utility model above-mentioned whole large-scale overpass bridge is split as bifurcated in the same way " fore-telling " the font fork bridge that two independences are not connected is small-sized overpass bridge, bifurcated in the same way " fore-telling " the font fork tunnel that is not connected with two independences is a minitunnel, finish the left-hand rotation of four roads in crossroad and the unimpeded function of keeping straight on respectively with these two small-sized overpass bridges and two minitunnels, in identical driving speed per hour, identical technology such as pontic gradient ginseng is wanted under the condition, 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 and each minitunnel shorten 30-35% than the total length of present large-scale overpass bridge, and two small-sized overpass bridges and two minitunnel gross areas reduce 30-50%; Substantially do not take road self ground in addition, and the underground and aboveground space on this ground; Just the utility model has reduced the degree that local damage damages integral body greatly; Reduced geology so greatly and changed the economic loss that causes damage, also can make the traffic of crossroad can not finish paralysis; In a word, the utility model risk that greatly reduces geological disaster.

Two, turn left and turn right shared left-hand bend bridge or left-hand bend tunnel: left-hand rotation bridge earth terminal or left-hand bend tunnel earth terminal are connected with the right-turn lane of ground, left side by-path, just can be used as the shared bridge of right-hand bend car or the shared tunnel of ground, left side by-path.The minimum widith in shared bridge or tunnel will reduce about 5.0 meters than the overall width of two independent bridges or two separate tunnel.The left-hand rotation bridge of the disclosed screen frame shape of the Figure of description of Chinese patent 200820230509.5 overpass bridge and right-hand rotation bridge are two independent bridges all.So whole composite bridge of the utility model or combination tunnel have reduced than the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge and have taken the ground circular diameter more than 10.0 meters.Then the utility model can be used for littler crossroad, and is spendable wider.

Three, the vehicle that leaves the crossroad broad arranged ground as merging the track section: two small-sized overpass bridges, be not connected with two minitunnels are independent, can arrive ground away from the vehicle of crossroad and merge the track with the vehicle that other leaves the crossroad on ground again, and not on bridge or in the tunnel, merge the track.Merging the track on ground can have very wide very long merging track section, is difficult for blocking up because of merging the track.Avoided the disclosed screen frame shape of the Figure of description overpass bridge of Chinese patent 200820230509.5 on pontic, to merge the too little too narrow and traffic congestion problem that causes of lane position.

Four, be same as the former circuit of plane traffic substantially and do not have unnecessary detouring: it is unimpeded that two-way six-lane crossroad craspedodrome motorway and the motor-driven road of left turning vehicle are had no road occupying, and solved the traffic congestion that produces because of the two road usual friendship at the parting of the ways, problem blocks the traffic.This is a kind of unnecessary circuit that detours that do not have, motor vehicles only have ascents and descents to be different from the plane traffic at the parting of the ways, and driving route is same as the driving route on the existing surface road that traffic lights are arranged substantially, do not change direction of traffic and the custom of people in the usual friendship crossroad, do not get lost because of unnecessary detouring in can current process at the parting of the ways, the engineering quantity of building bridge in addition is less than existing any intercommunicated overpass, saves the bridge construction engineering cost.

Five, the little crossroad of two-way six-lane can be used: the utility model is only used two, and " fore-telling " font Y-shaped arch bridge and two are combined into the means of transportation of crossroad in bifurcated " fore-telling " font fork tunnel in the same way in the same way, it is unimpeded fully just to have realized that the crossroad has no road occupying and conflicts, than the existing intercommunicated overpass that detours, reduced the length of bridge in a large number with the disclosed screen frame shape of the Figure of description of Chinese patent 200820230509.5 overpass bridge, reduced floor space in a large number, ground and space round diameter have only 55 meters two-way six-lane small size crossroad, city can realize that also grade separation is unimpeded at the parting of the ways to make it, promptly do not intersect the road occupying conflict point, also the section of interweaving not provides new design scheme for solving the global arterial street automobile traffic problem of blocking up.

Six, only use one deck bridge: one deck overpass bridge is only used on ground.Littler to the civic landscape influence.

Seven, human and vehicle shunting is realized on ground at the parting of the ways, part is gone back in the people: in the crossroad of using this patent facility, motor vehicle all moves under on the bridge or tunnel, the ground, diagonal angle under center and two the left-hand bend bridges do not have motor vehicle on the ground, so can have free passage for pedestrian and non motorized vehicle at the parting of the ways.

Eight, more miniaturization of ground overpass bridge: the crossroad of using the utility model means of transportation, the all traffic from overpass bridge or the tunnel of craspedodrome motor vehicles and left-hand bend motor vehicles, do not have motor vehicles current, have only pedestrian and non motorized vehicle current from ground, crossroad from ground, crossroad.Then the overpass bridge on ground only needs 2.5-3.0 rice headway just can satisfy the current requirement of pedestrian and non motorized vehicle at the parting of the ways.2.5-3.0 the overpass bridge of rice headway reduces 1.5-2.0 rice headway than 4.5 meters headway overpass bridges of current motor vehicle, can reduce the 30%-40% headway, then just can reduce the pontic length of 30%-40%, as long as the total length of " fore-telling " font Y-shaped arch bridge is about 400.0 meters in the same way to make two of the present utility model, and this makes overpass bridge of the present utility model can not produce two too short and out of use problems of the road between the crossroad.

Inventive point of the present utility model is:

One, establish same number, identical, discrete two small-sized " fore-telling " the font overpass bridges of bifurcated direction and two small-sized " fore-telling " font tunnels by the bar number of ground, crossroad by-path: the disclosed screen frame shape of the Figure of description overpass bridge of Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass " is the large-scale screen frame formula of an integral body overpass bridge that is connected as a single entity, and the whole three-dimensional bridge of the various runways in crossroad is connected as one.And the utility model is with prong two composite bridges of bifurcated " fore-tellings " font fork bridge composition in the same way facing each other, with prong facing each other two in the same way bifurcated " fore-telling " font fork tunnel form a combination tunnel, composite bridge on the ground face both become three-dimensional criss-cross construction below ground in the tunnel with combination, do not take road self ground in addition, and the underground and aboveground space on this ground, make the multilevel traffic fully respectively of bridge and tunnel, without any intersecting the road occupying point.The means of transportation miniaturization is not connected, can reduce qualitative changeization partly and damage, make the small-sized crossroad of two-way six-lane the aspect such as can use, all be better than the disclosed screen frame formula of the Figure of description overpass bridge of Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass " the means of transportation of whole crossroad.That is to say: from single comparison, the utility model is split as two small-sized " fore-telling " font overpass bridges and two small-sized " fore-telling " font tunnels to screen frame formula overpass bridge; From integral body relatively, the combination means of transportation in two small-sized " fore-telling " font overpass bridges and two small-sized " fore-telling " font tunnels become the little cross of floor space, rather than the wide screen frame shape of floor space.

Two, traffic conflict point is moved on to away from the by-path position 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, the i.e. position in the scope at the parting of the ways not, solution is from the direct lane and the left turn lane of Different Ground by-path, and the conflict of the intersection road occupying between the left turn lane, but creationary this two classes traffic conflict point is moved on to away from multilevel traffic transport solution conflict on four ground by-paths of crossroad, thereby can take the ground and the space of crossroad minimumly.The utility model requires to reduce greatly to the annular region floor area of crossroad.Means of transportation of the present utility model just can be built up in ground and the space of crossroad diameter more than 55 meters, realize that the crossroad access of old city six-lane is unimpeded, stop up the meaning that initiative is arranged for solving the little crossroad access in old urban area.

Three, on the by-path of the ground on two opposites, the ground of craspedodrome bridge prolongs the left-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 bifurcated " fore-telling " font fork bridge common play the bridge earth terminal more becomes three-dimensional decussate texture near two straight bridge single file sections of grouping bridge and two straight tunnels, tunnel single file section of dividing into groups center; Straight bridge earth terminal is near the opposite bifurcated section ground connection before of bifurcated " fore-tellings " font fork bridge in the same way, so straight bridge earth terminal has been reserved the opposite high position section leftward space of bifurcated " fore-telling " font fork bridge in the same way, allow the curved bridge single file section in a left side on opposite can be directly at the craspedodrome arch bridge bifurcated on left-hand bend one side and opposite, two bridge bifurcateds can directly turn left the left-hand bend vehicle and do not need unnecessary detouring, the vehicle that leaves straight bridge earth terminal can be passed from the turn left ground, bifurcated section below of bridge of opposite face, realize the multilevel traffic of through vehicles and opposite left-hand bend vehicle, and have only the height of one deck bridge.

Four, under the by-path of the ground on two opposites, the ground in craspedodrome tunnel prolongs the left-hand bend tunnel that the track strides across the opposite: keeping straight on relatively is two two-way craspedodrome tunnels that rightabout is kept straight on, separate, not shared tunnel; Be straight tunnel earth terminal than the opposite in the same way bifurcated " fore-telling " font fork tunnel enter the tunnel earth terminal more becomes three-dimensional decussate texture near two straight bridge single file sections of grouping bridge and two straight tunnels, tunnel single file section of dividing into groups center jointly; Straight tunnel earth terminal is near the opposite bifurcated section ground connection before in bifurcated " fore-tellings " font fork tunnel in the same way, so straight tunnel earth terminal reserved the opposite in the same way the deep-seated in bifurcated " fore-telling " font fork tunnel put the section leftward space, allow curved tunnel, the left side single file section on opposite can be directly at the craspedodrome tunnel bifurcated on left-hand bend one side and opposite, two tunnel bifurcateds can directly turn left the left-hand bend vehicle and do not need unnecessary detouring, the vehicle that leaves straight tunnel earth terminal can be striden across from the turn left ground, bifurcated section top in tunnel of opposite face, realize the multilevel traffic of through vehicles and opposite left-hand bend vehicle, and as long as the degree of depth in one deck tunnel.

Five, the ground of left-hand bend bridge prolongs craspedodrome bridge and the left-hand bend bridge of wearing ground, left side by-path under the track: the left bridge single file section of bending directly arrives near the ground connection in zone, high position of pitching bridge near bifurcated in the same way " fore-telling " font in left side by the left-hand bend direction, its ground prolongs track and this regional multilevel traffic in high position of bifurcated " fore-tellings " font fork bridge in the same way, and what just solved the straightgoing vehicle of the ground by-path that left-hand bend vehicle and left-hand bend will arrive and left turning vehicle intersects the road occupying collision problem.The left-hand bend vehicle does not detour, and has reduced unnecessary traffic conflict point.

Six, prolongation track in the ground in left-hand bend tunnel strides across the craspedodrome tunnel and the left-hand bend tunnel of ground, left side by-path: a left side is bent tunnel single file section and is put near the ground plane in zone by the direct arrival of left-hand bend direction near the deep-seated in bifurcated in the same way " fore-telling " the font fork tunnel in left side, its ground prolong track with this in the same way bifurcated " fore-tellings " the font deep-seated of pitching the tunnel put regional multilevel traffic, what just solved the straightgoing vehicle of the ground by-path that left-hand bend vehicle and left-hand bend will arrive and left turning vehicle intersects the road occupying collision problem.The left-hand bend vehicle does not detour, and has reduced unnecessary traffic conflict point.

Seven, the left-hand bend bridge is designed to left and right turning combined bridge: the left-hand bend bridge is not striden across bifurcated " fore-telling " font fork tunnel in the same way, left side, and left-hand rotation bridge earth terminal can be communicated with the right-turn lane of ground, left side by-path, and the left-hand bend bridge just becomes left and right turning combined bridge.And do not need two bridges to use as left and right turning respectively.

Eight, the left-hand bend Tunnel Design is become the dual-purpose tunnel of left and right turning: the left-hand bend tunnel is not passed left side bifurcated " fore-telling " word jag bridge in the same way, and left-hand bend tunnel earth terminal can be communicated with the right-turn lane of ground, left side by-path, and the left-hand bend tunnel just becomes the dual-purpose tunnel of left and right turning.And do not need two tunnels to use as left and right turning respectively.
