Description
Technical field
The invention belongs to the tunnel that makes the right-angled intersection automobile traffic unimpeded, particularly four independently the bifurcated tunnel straightgoing vehicle) and right-hand bend motor vehicle (above abbreviation: the have no road occupying unimpeded combining structure in a plurality of tunnels of the conflict right-hand bend car) be combined into the craspedodrome motor vehicle that can make the crossroad (above abbreviation:.
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 under the crosspoint, two road are overlapping to have become a road, and the motor vehicles under the two road can only a shared road under node, has lost the path resource of half.Add the mixed row of pedestrian, bicycle and motor vehicle down again, 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 the tunnel again, but in existing upright civilian Tunnel Design scheme, can make craspedodrome tunnel, crossroad and right-hand bend tunnel have no road occupying the conflict the tunnel minimum diameter below 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.
Summary of the invention
The purpose of this invention is to provide the road track that meets existing left lateral system traffic specification arranges, small size crossroad at two-way six-lane can be built, four " Y " font bifurcated tunnels are combined into the conflict that has no road occupying of craspedodrome tunnel and right-hand bend tunnel, and there is long merging track section in a plurality of tracks of leaving the crossroad and is difficult for the unimpeded tunnel of many tunnels combined type of traffic congestion.
The present invention solves and intersects the design of road occupying conflict point and be: a plurality of conflict points of right-angled intersection plane traffic are divided into three kinds of conflict points: first kind is that the right-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 right-turn lane has the road occupying of intersection to conflict with the direct lane and the right-turn lane of arrival ground by-path.
Solve first kind, there is the technical scheme of road occupying conflict in the right-hand bend car tunnel on straightgoing vehicle tunnel and opposite: craspedodrome tunnel and right-hand bend tunnel under each ground by-path 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 going up the right-hand bend tunnel in " Y " font bifurcated tunnel to ground from the opposite, solved direct lane and opposite the right-turn lane 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: intersecting the craspedodrome tunnel that travels becomes multilevel traffic in the centre at the parting of the ways, has solved four straightgoing vehicle tunnels 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 right-turn lane with the direct lane of arrival ground by-path and right-turn lane have intersects the technical scheme of road occupying conflict: with the track, ground of leaving the crossroad that the tunnel end is communicated with that goes out in right-hand bend tunnel, stride across above the bifurcated tunnel [craspedodrome tunnel and right-hand bend tunnel] of the ground by-path that arrives from this right-hand bend tunnel, solved the collision problem that intersects of the direct lane of right-turn lane and the ground by-path of arrival and right-turn lane.This technical scheme has solved eight road occupying conflict points.
Like this, the crossroad of plane traffic, four direct lanes and four 16 total road occupying conflict points of right-turn lane have been realized multilevel traffic fully, no longer include the road occupying conflict point.
The design of the new function of the present invention: make up the tunnel and take the ground and the underground space for reduce the present invention as far as possible, traffic route fully can be identical the right-hand bend tunnel and the left-hand bend tunnel of this ground, right side, right-hand bend tunnel by-path, the right side of travelling with an energy rightabout, a left side merge the tunnel, and right side, the width that turns left to merge the tunnel can reduce the width on 5.0 meters right left sides than side by side two the independent right-hand bend tunnels and the overall width in left-hand bend tunnel.So, the present invention is the mode of two independent bridges without the disclosed right side of Figure of description, the left-hand rotation of Chinese patent 200820230509.5 " the directly right side, left-hand rotation interchange overpass ", but the right-hand bend Tunnel Design one-tenth right side, the merging tunnel that turns left are reached minimizing and make up the purpose that the tunnel takies ground and space.
The Figure of description of Chinese patent 200820230509.5 " directly right, left-hand rotation interchange overpass " is disclosed to be the collision problem that has no road occupying that solves crossroad autobus with overpass bridge.But in the Jiu Cheng crossroad is commercial strategic point, overpass bridge has considerable influence to the commerce of crossroad, so the present invention solves the collision problem that has no road occupying of crossroad autobus with the tunnel, so that influence crossroad commerce less as far as possible, make the crossroad can not want the problem that point duty such as traffic lights does not have traffic congestion yet again.
The driving route that the present invention 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 right-hand bend vehicle not only will accomplish not have the road occupying conflict point, will accomplish that also the through vehicles, right-hand bend vehicle, left-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 present invention is located at ground merging the track section, is the rule that ground level road is divided though merge the track section, does not belong to structure content of the present invention, and tunnel structure of the present invention can make vehicle can obtain to merge the track section on ground.And the disclosed screen frame shape of the Figure of description overpass bridge of Chinese patent 200820230509.5 " directly right, left-hand rotation interchange overpass " can be regarded as at a plurality of pontics that leave the right-angled intersection center in a some merging track, make through vehicles, right-hand bend vehicle and left-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 present invention 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 traffic congestion problem that produces very little of track point.So, through vehicles and right-hand bend vehicle that the present invention 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 in the Different Ground by-path tunnel, 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 present invention can reduce at double because of merging the too narrow traffic congestion problem that produces very little of track point.
The design of new construction of the present invention:
One, the right-hand bend tunnel does not pass bifurcated " Y " font fork tunnel in the same way, right side: with four bifurcated " Y " font fork tunnels in the same way independently, divide prong composition facing each other two grouping tunnels, two groups of straight tunnel single file sections in two grouping tunnels become three-dimensional decussation structure, but each does not pass in the right-hand bend tunnel in bifurcated " Y " font fork tunnel in the same way, do not stride across bifurcated in the same way " Y " the font fork tunnel on the right, but the right-hand bend tunnel is communicated with ground putting above the section near the deep-seated in bifurcated in the same way " Y " font on the right fork tunnel, not only make the vehicle on the right-hand bend tunnel can go up ground, stride across bifurcated in the same way " Y " the font fork tunnel on the right from ground, this right-hand bend tunnel is communicated with the left turn lane of ground, right side by-path, vehicle on this left turn lane can be realized, this right-hand bend tunnel is become the right side with tunnel, the outside face in this tunnel of turning right, dual-purpose tunnel turns left.
Two, with four bifurcated " Y " font fork tunnels in the same way independently, divide prong composition facing each other two grouping tunnels, four craspedodrome tunnels in two grouping tunnels carry out multilevel traffic in the by-path position, ground away from the crossroad in the right-hand bend tunnel in bifurcated " Y " font fork tunnel in the same way with the opposite respectively.The shape of right curved tunnel single file section is the arcuate structure that becomes three-dimensional decussate texture central area indent to two groups of straight tunnel single file sections in two grouping tunnels, with the grade separation position in other tunnel also at ground by-path away from the center, crossroad, prolonged the right-hand bend length of tunnel, thereby reduced the right-hand bend tunnel because of the tunnel length that the gradient needs will take very large-area problem at the parting of the ways, making little crossroad, old urban area also can carry out vehicle, not intersect road occupying unimpeded.This just requires two of opposite face, and two craspedodrome tunnels of bifurcated " Y " font fork tunnel rightabout driving are separate in the same way, need not same tunnel, and vertical dislocation is arranged, promptly the underground tunnel construction sections that goes out tunnel construction sections straight tunnel earth terminal and that craspedodrome tunnel, opposite in a craspedodrome tunnel advances between the tunnel earth terminal spacing distance to be arranged and not in same position jointly, the craspedodrome tunnel go out the straight tunnel of tunnel construction sections earth terminal more near the center, crossroad, straight tunnel earth terminal is as long as putting regional ground plane near the stage casing deep-seated in craspedodrome tunnel, opposite, just abdicate the following side space on right side for craspedodrome tunnel, opposite, promptly allow the right-hand bend tunnel on opposite directly go out right curved tunnel single file section, in addition the ground by-path position multilevel traffic at the parting of the ways of the right-hand bend tunnel of realizing craspedodrome tunnel and opposite at the side bifurcated of turning right.Be positioned at the opposite in the same way among the branch prong in bifurcated " Y " font fork tunnel as long as there is the part of two straight tunnel single file sections in the grouping tunnel to go out the Close Tunnel section, becoming straight tunnel single file section partly to go out the tunnel section embeds the opposite and divides structure among the prong in bifurcated " Y " font fork tunnel in the same way, but straight tunnel single file section is not passed right curved tunnel, opposite single file section, makes the right side of this position bend the structure that does not have straight tunnel single file section above the tunnel single file section and be one deck tunnel.Center at the parting of the ways, two groups of straight tunnel single file sections in two grouping tunnels become multilevel traffic.Under ground by-path away from the center, crossroad, ground of each right curved tunnel single file section prolongs the track and all becomes multilevel traffic with bifurcated in the same way " Y " the font fork tunnel of the ground by-path that arrived of turning right, but right curved tunnel single file section is not passed and bifurcated in the same way " Y " the font fork tunnel of the ground by-path that arrived of turning right.
Structure of the present invention is:
The combination tunnel in four independences of left lateral system length shape " Y " font bifurcated tunnel, comprise four bifurcated tunnels, it is characterized in that: all there are a craspedodrome tunnel 2 and a right-hand bend tunnel 3 in each bifurcated tunnel, right-hand bend tunnel 3 is positioned at the right side in craspedodrome tunnel 2, right-hand bend tunnel 3 is all at a side and craspedodrome tunnel 2 bifurcateds of turning right, this bifurcation is a bifurcation 15, make a craspedodrome tunnel 2 and a right-hand bend tunnel 3 form " Y " font bifurcated tunnel, then four bifurcated tunnels become four bifurcated " Y " font fork tunnels 1 in the same way;
Each the craspedodrome tunnel 2 in bifurcated " Y " font fork tunnel 1 and right-hand bend tunnel 3 has and advances tunnel earth terminal 4 jointly in the same way, and advance jointly tunnel earth terminal 4 to two tunnels between the bifurcation 15 section 14 side by side; 1 stage casing deep-seated is put the zone, right-hand bend tunnel 3 and craspedodrome tunnel 2 bifurcateds in the fork of bifurcated " Y " font in the same way tunnel; Right-hand bend tunnel 3 leaves the deep-seated in craspedodrome tunnel 2 and puts the regional bifurcated section 7 that is; Craspedodrome tunnel 2 also has a straight tunnel earth terminal 5, and right-hand bend tunnel 3 also also has a right-hand rotation tunnel earth terminal 6; From bifurcation 15 to straight tunnel earth terminal 5 is straight tunnel single file section 8; From bifurcation 15 to right-hand rotation tunnel earth terminal 6 is right curved tunnel single file section 13;
Divide prong relative two to form a grouping tunnel in bifurcated " Y " font fork tunnel 1 in the same way, four in the same way bifurcated " Y " font fork tunnel 1 form two grouping tunnels respectively; 8 one-tenth three-dimensional decussate textures of two groups of straight tunnel single file sections in two grouping tunnels; Two grouping tunnels are divided into two embedded grouping tunnels and two kinds in single embedded grouping tunnel; In two embedded groupings tunnel, the part section of two straight tunnel single file sections 8 lays respectively at the opposite in the same way among the branch prong in bifurcated " Y " font fork tunnel 1, and then two straight tunnel single file sections 8 in two embedded grouping tunnels all are microscler straight tunnel single file section 8-1; In single embedded grouping tunnel, straight tunnel single file section 8 is divided into microscler straight tunnel single file section 8-1 and the straight tunnel of brachmorphy single file section 8-2, the part section of microscler straight tunnel single file section 8-1 is positioned at the opposite in the same way among the branch prong in bifurcated " Y " font fork tunnel 1, and the straight tunnel of brachmorphy single file section 8-2 is positioned at the place in the same way between the straight tunnel single file section 8 in bifurcated " Y " font fork tunnel 1 and another tunnel that divides into groups; Pitch between the tunnel 1 on bifurcated in the same way " Y " the font fork tunnel 1 that right curved tunnel single file section 13 is positioned at the place and right side bifurcated " Y " font in the same way.
The present invention turns right, and the design feature in tunnel 3 makes right-hand bend tunnel 3 become the right side, shared tunnel turns left, reduce the floor space of combination central area, tunnel: between bifurcated " Y " the font fork tunnel 1, tunnel 1 pitched in bifurcated in the same way " Y " font that 3 right sides, this right-hand bend tunnel were not passed, do not striden across to curved tunnel, the right side in the tunnel 3 of promptly turning right single file section 13 in the same way for bifurcated in the same way " Y " the font fork tunnel 1 that right curved tunnel single file section 13 is positioned at the place and right side.Right-hand rotation tunnel earth terminal 6 is communicated with the left turn lane of the ground by-path on right side, and the left turning vehicle of ground, right side by-path can directly use as the left-hand bend tunnel with the outside in this right-hand bend tunnel 3, realizes.The right-hand rotation car of just adjacent ground by-path and left-hand rotation car can reach the purpose of turning separately in shared right-hand bend tunnel 3, just turn right car in the right-hand bend tunnel 3 by the inboard tunnel faces of 8 one-tenth three-dimensional decussate textures of two groups of straight tunnel single file sections, and the left-hand rotation car is at tunnel face in the outer part.Realize turning right and turning left in right-hand rotation car and the shared right-hand bend of left-hand rotation car tunnel 3, than realizing that with two tunnels in right-hand rotation tunnel and left-hand rotation tunnel right-hand rotation and left-hand rotation still less take the ground and the underground space of crossroad, become the more combination tunnel of miniaturization, help to use this combination tunnel, also reduce the built tunnel expense in littler crossroad.
The present invention's length that the design feature in arch tunnel 2 increase to merge the track of keeping straight on prevents traffic congestion: with independent discrete four bifurcated " Y " font fork two grouping tunnels of 1 fen prong composition facing each other, tunnel in the same way, straight tunnel single file section 8 form of structure in two grouping tunnels: the part section of the straight tunnel of each of two grouping tunnels single file section 8 is positioned at the opposite in the same way among the branch prong in bifurcated " Y " font fork tunnel 1, but do not stride across or do not pass opposite curved tunnel, the right side single file section 13 in bifurcated " Y " font fork tunnel 1 in the same way, this grouping tunnel is two embedded grouping tunnels.Straight tunnel earth terminal 5 from straight tunnel single file section 8 goes out the through vehicles in tunnel on ground like this, with from the right side in the same way the right-hand rotation tunnel earth terminal 6 in bifurcated " Y " font fork 1 right-hand bend tunnel 3, tunnel go out the right-hand bend vehicle merging track of tunnel to ground, promptly the through vehicles and the right-hand bend vehicle in bifurcated " Y " font fork tunnel 1 merge the track on ground in the same way from two, then can merge the track at long section in track, ground, rather than only be confined to a merging track point, can solve like this because of merging the too narrow very little traffic congestion problem that causes in site in track.
Bifurcated " Y " font fork tunnel 1 is meant that right-hand bend tunnel 3 and craspedodrome tunnel 2 have one section side by side in the same way, but right-hand bend tunnel 3 is put regional right side at the stage casing in craspedodrome tunnel 2 deep-seated bifurcation 15 is arranged.In near right-hand bend tunnel 3 the bifurcation 15 and craspedodrome tunnel 2 sections height between the clean deep space that closes the symbol traffic specification is arranged preferably, make it can pass through motor vehicles above face of land.Turn right as motor vehicles and use in right-hand bend tunnel 3." in the same way " be meant that the right-hand bend tunnel 3 in each " Y " font fork tunnel is all identical with the bifurcated direction in craspedodrome tunnel 2, promptly each right-hand bend tunnel 3 is all at the right side in craspedodrome tunnel 2 bifurcated, the directly right-hand rotation with other any tunnel grade separation.So one in the same way the global shape in bifurcated " Y " font fork tunnel 1 be: a right-hand bend tunnel 3 and a craspedodrome tunnel 2 are side by side advancing tunnel earth terminal 4 jointly to bifurcation 15, this side by side section be two tunnels side by side sections 14.Craspedodrome tunnel 2 behind the bifurcated is a straight tunnel single file section 8, and the right-hand bend tunnel 3 behind the bifurcated is a right curved tunnel single file section 13.
The craspedodrome tunnel 2 in same bifurcated in the same way " Y " font fork tunnel 1 and the tunnel earth terminal 4 that advances jointly in right-hand bend tunnel 3 can be zonules, and the tunnel 2 of then keeping straight on advances tunnel point and right-hand bend tunnel 3 advances the tunnel point in same area; In this same area, craspedodrome tunnel 2 enters tunnel point and right-hand bend tunnel 3, and to advance the tunnel point can be same position, or certain longitudinal separation is arranged.
Craspedodrome tunnel 2 is the current tunnels of two ground by-paths that are used for the crossroad opposite face, and " craspedodrome " is meant that motor vehicles arrive the meaning of opposite, crossroad road, and " craspedodrome " is not meant the shape in tunnel, and is meant the purposes in tunnel.
Right-hand bend tunnel 3 is the right-hand bend tunnels that are used for crossroad left lateral traffic system, and " right-hand bend " is that purposes is the meaning of turning right.
The bifurcated section 7 in right-hand bend tunnel 3 is the tunnel construction sections that are used for crossing from ground from the motor vehicles in the craspedodrome tunnel 2 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 7 need satisfy is put regional bifurcated so the right-hand bend tunnel 3 in same bifurcated in the same way " Y " font fork tunnel 1 is preferably in the deep-seated that satisfies traffic specification with craspedodrome tunnel 2.
Right-hand rotation tunnel earth terminal 6 preferably is positioned near the ground the bifurcation 15 in bifurcated in the same way " Y " font fork tunnel 1 of the ground by-path that right-hand bend will arrive, right curved tunnel single file section 13 does not stride across, does not pass bifurcated in the same way " Y " the font fork tunnel 1 of the ground by-path that right-hand bend will arrive, so that the right-hand bend motor vehicles stride across bifurcated in the same way " Y " the font fork tunnel 1 of the ground by-path that is arrived from ground.The right-hand bend motor vehicles in ground and left side in the same way the through vehicles in bifurcated " Y " font fork 1 craspedodrome tunnel 2, tunnel merge the track, long ground, merging track section can be arranged, rather than have only one to merge the track point.Avoided merging track point too narrow very little and traffic congestion problem of producing below the tunnel.
The stage casing in bifurcated " Y " font fork tunnel 1 is provided with deep-seated and puts the zone in the same way, so that from the left side in the same way the right-hand bend vehicle in bifurcated " Y " font fork tunnel 1 from right-hand rotation tunnel earth terminal 6 to ground after from it face stride across, bifurcated " Y " font fork tunnel 1 can multilevel traffic with the right-hand bend vehicle from the left side in the same way thereby realize this.
The grouping tunnel is by minute prong relative two combining structure in bifurcated " Y " font fork tunnel 1 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 the right-hand bend car is realized the combination tunnel of turning right.A crossroad needs two grouping tunnels, 8 one-tenth three-dimensional decussate textures of two groups of straight tunnel single file sections in two grouping tunnels.
Two groups of straight tunnel single file sections 8 that " cross " meaning of 8 one-tenth three-dimensional decussate textures of two groups of straight tunnel single file sections in two grouping tunnels does not limit two grouping tunnels are 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 tunnel single file section 8 has bending also still two groups of straight tunnel single file sections 8 in two grouping tunnels to be considered as decussate texture.But two groups of straight tunnel single file sections 8 up and down in two grouping tunnels are not connected, and discrepancy in elevation distance is up and down arranged, and the motor vehicles that can satisfy in two tunnels are current.
The optimum position of straight tunnel earth terminal 5: the straight tunnel earth terminal 5 of microscler straight tunnel single file section 8-1 is near the opposite bifurcated section 7 top ground locations in bifurcated " Y " font fork tunnel 1 in the same way, the straight tunnel earth terminal 5 of the straight tunnel of brachmorphy single file section 8-2 ground location above near the straight tunnel single file section 8 in another grouping tunnel.As long as make its through vehicles stride across bifurcated section 7 from ground, then the degree of depth of bifurcated section 7 can reduce as far as possible, promptly the height in one deck tunnel.
The preferred structure in right-hand bend tunnel 3: curved tunnel, the right side in right-hand bend tunnel 3 single file section 13 is preferably to the arcuate structure of 8 one-tenth three-dimensional decussate textures of two groups of straight tunnel single file sections central area in two grouping tunnels indent.Satisfy the gradient for the length that prolongs right curved tunnel single file section 13 and meet the traffic specification requirement, and take ground, crossroad or underground position as far as possible less, and the arcuate structure that the turn fractions of tunnel single file section 13 is arranged to concave is bent on the right side.This preferred structure makes the present invention can be used for having only more than 65 meters between place, diagonal angle, the crossroad building, and the crossroad of the above width in eight tracks is arranged between the building of two-way six-lane both sides, can both build the unimpeded tunnel of combination of the present invention.This just makes the present invention can be used for the crossroad, arterial highway in old city, realizes crossroad, the old arterial street straightgoing vehicle that people wish and change cart having no road occupying unimpeded.
Curved tunnel, the right side single file section 13 min. turning radius design of arc concaves: the central point with 8 one-tenth three-dimensional decussate textures of two groups of straight tunnel single file sections in two grouping tunnels is the center, same grouping tunnel is L to the right curved tunnel of two arcs of stereo cross shape structure centre indent single file section 13 relative beeline length, the min. turning radius of two the right curved tunnel of arc single file sections 13 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 right curved tunnel of arc 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 left-hand bend of left lateral system, not the subject matter that the present invention will solve so turn left.Turning left from ground can be without the grade separation tunnel, but will have the road occupying of intersection to conflict with bicycle and pedestrian.For avoiding this intersection road occupying conflict, can be that the right side is widened with the outside in right-hand bend tunnel 3, the left turning vehicle that is used for ground, right side by-path uses, and the tunnel 3 of just turning right becomes the right-hand bend car of this ground by-path and the common dual-purpose tunnel that uses of left turning vehicle of ground, right side by-path.The structure in right-hand bend tunnel 3 is without any variation, just become the right side, dual-purpose tunnel turns left, it is unimpeded fully to make the present invention become four craspedodrome roads of crossroad, four right-hand rotation bends, four left-turning pathways, the complete intercommunicating overpass tunnel that whole tracks, crossroad are unimpeded has promptly been realized in the full intercommunication combination tunnel of neither one intersection road occupying conflict point.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 left-hand bend service bridge, and promptly turn left bridge and right-hand bend bridge are two graded crossing bridges side by side.According to the overpass bridge design specifications, the minimum widith in the right side of the present invention, the dual-purpose tunnel that turns left can be 10.0 meters, but the left-hand bend bridge of the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge and right-hand bend bridge minimum widith side by side are 15.0 meters.Consequently, right, the left-hand rotation of one-sided realization, the present invention has reduced by 5.0 meters occupation of land width; And the whole combination of the present invention tunnel minimum takies the circle on ground directly through 65.0 meters, and the circle that takies ground than the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge minimum has directly reduced by 10.0 meters width through 75.0 meters.This stand out of 10.0 meters, make combination of the present invention tunnel 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 combination of the present invention tunnel usability widely be arranged than the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge, combination of the present invention tunnel 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.
What " right side " " left side " in the right of the present invention or the left side, the right side or the left side, right side left side was meant that the people stands in some bifurcateds in the same way " Y " font fork tunnel 1 enters tunnel earth terminal 4 positions jointly, in the face of the stereo cross shape structure centre that two groups of straight tunnel single file sections 8 in two grouping tunnels are formed goes to judge " right side " or " left side ".
Two tunnels of the present invention section 14 side by side comprise two tracks at least.

Intersection road occupying conflict of the present invention refers to the traffic conflict between the motor vehicles at the parting of the ways.
Deep-seated of the present invention is put the tunnel section that the zone is meant the top motor vehicles height that can pass through.
It is that " car " or " vehicle " of bicycle is meant motor vehicle or refers to motor vehicles that the present invention does not indicate.
Advantage of the present invention:
One, large-scale overpass bridge is divided into four small-sized " Y " font tunnels, prevent 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 a large-scale overpass bridge of integral body that is connected as a single entity, the total length of a large-scale overpass bridge of integral body 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 present invention is with four small-sized " Y " font tunnels, and any qualitative changeization partly only has damage to this localized tunnel, and whole tunnels, crossroad can not be used, i.e. local damage does not influence integral body, has improved the safety of means of transportation.Miniaturization can still less take the ground beyond the by-path of ground, and the underground and aboveground space on this ground.
Two, the right-hand bend tunnel can be used as and turns right and the shared tunnel that turns left: the right-hand rotation tunnel earth terminal in right-hand bend tunnel is connected with the left turn lane of ground, right side by-path, and the right-hand bend tunnel just can be used as the shared tunnel of left turning vehicle of ground, right side by-path.The minimum tunnel face width degree in the right-hand bend and the shared tunnel that turns left will reduce by 5.0 meters right left sides than the overall width with two separate tunnel in right-hand rotation tunnel and left-hand rotation tunnel.The right-hand rotation bridge of the disclosed screen frame shape of the Figure of description of Chinese patent 200820230509.5 overpass bridge and left-hand rotation bridge are two independent bridges.So, the circle that the whole combination of the present invention tunnel minimum takies the ground and the underground space is directly through 65.0 meters, and the circle that takies ground and space than the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge minimum has directly reduced by 10.0 meters width through 75.0 meters.Combination then of the present invention tunnel can be used for littler crossroad, and is spendable wider.
Three, the vehicle that leaves the crossroad has the ground of broad as merging the track section: the through vehicles that brings out the tunnel from the straight tunnel ground connection of straight tunnel single file section is kept straight on ground and is striden across above bifurcated in the same way " Y " the font fork Tunnel Right turning tunnel on opposite, with from the right side in the same way the right-hand bend tunnel in bifurcated " Y " font fork tunnel go out the right-hand bend vehicle merging track of tunnel to ground, then can merge the track, avoid 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 at long ground section.
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 right-hand bend motorway 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 descending and upward slope to be different from the plane traffic at the parting of the ways, and driving route is same as the existing driving route that the surface road of traffic lights is arranged substantially, do not change direction of traffic and the custom of people in the usual friendship crossroad, can not get lost because of detouring redundantly in the current process at the parting of the ways, save the built tunnel engineering cost.
Five, the little crossroad of two-way six-lane can be used: the present invention only uses four combinations in bifurcated " Y " font bifurcated tunnel in the same way, it is unimpeded fully just to have realized that the crossroad has no road occupying and conflicts, reduced length in a large number than the existing intercommunicated overpass that detours, floor space and space have been reduced in a large number, make it have only 65 meters two-way six-lane small size crossroad, city can realize that also grade separation is unimpeded at round diameter, 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, one deck tunnel is only used in through vehicles and the multilevel traffic of right-hand rotation vehicle: no matter be the right-hand bend tunnel of striding the opposite on the through vehicles, stride the craspedodrome tunnel and the right-hand bend tunnel on right side on the vehicle of still turning right, all only use one deck tunnel.
Inventive point of the present invention is:
One, establish same number, basic identical structure, discrete small-sized separate tunnel 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 " directly right, left-hand rotation interchange overpass " is a large-scale overpass bridge of integral body that is connected as a single entity, and whole overpass bridges of the various runways in crossroad are connected as one.And it is considered herein that, from the tunnel of Different Ground by-path after through the crossroad, tunnel unnecessary and from other ground by-path is connected, more can realize merging the track with vehicle from the tunnel of other ground by-path, sail out of this crossroad, also more difficult traffic congestion, so the present invention does not interconnect the tunnel from the Different Ground by-path, also comprise through not interconnecting behind the crossroad, make four ground by-paths of crossroad use respectively four in the same way bifurcated " Y " font fork minitunnel, discretely be combined into a combination tunnel.And the combination tunnel of this four minitunnels is preventing that geology from having changed, having widened the disclosed screen frame shape of the Figure of description overpass bridge that the aspects such as length that merge the track are better than Chinese patent 200820230509.5 " directly right, left-hand rotation interchange overpass ".That is to say: from single comparison, the present invention is split as four small-sized " Y " font tunnels to screen frame formula overpass bridge; From integral body relatively, the combination tunnel in four small-sized " Y " font tunnels becomes the little cross of floor space, rather than the wide screen frame shape of floor space.
Two, the tunnel in craspedodrome tunnel and right-hand bend tunnel does not pass through mutually: this craspedodrome tunnel does not stride across the right-hand bend tunnel on opposite, realizes keeping straight in the right-hand bend tunnel that just makes vehicle in the craspedodrome tunnel stride across the opposite from ground; And the right-hand bend tunnel does not stride across right side the craspedodrome tunnel and the right-hand bend tunnel in bifurcated " Y " font fork tunnel in the same way, makes the vehicle in the right-hand bend tunnel stride across right side the craspedodrome tunnel and the right-hand bend tunnel in bifurcated " Y " font fork tunnel in the same way from ground.This structure makes through vehicles and the right-hand rotation vehicle in different bifurcated in the same way " Y " the font fork tunnels can realize merging the track on ground, as long as merge the merging track section that just can there be longer distance in the track, be difficult for because of merging too little too narrow traffic congestion the in track on ground.
Three, traffic conflict point is moved on to away from the by-path position of crossroad go multilevel traffic: the present invention 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 right-turn lane of Different Ground by-path, and the conflict of the intersection road occupying between the right-turn lane, but the creationary by-path position, four ground that this two classes traffic conflict point is moved on to away from the crossroad solves traffic conflict, thereby can take the ground and the underground width of crossroad minimumly.This unimpeded structure reduces greatly to the annular region area requirements of crossroad.As long as between the building of ground by-path the above width in eight tracks is arranged, there are the ground and the underground space more than 65 meters just can build up the unimpeded tunnel of combination of the present invention with the crossroad diameter, the crossroad access of realizing old city six-lane is unimpeded, stops 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 in craspedodrome tunnel prolongs the right-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 the tunnel earth terminal that advances jointly in bifurcated " Y " font fork tunnel more intersect the center near the stereo cross in two groups of craspedodrome tunnels in two grouping tunnels; Straight tunnel earth terminal near the opposite in the same way the deep-seated in bifurcated " Y " font fork tunnel put zone or ground connection before this, so straight tunnel earth terminal reserved the opposite in the same way the deep-seated in bifurcated " Y " font fork tunnel put the section rightward space, allow curved tunnel, the right side single file section on opposite can be directly at the craspedodrome tunnel bifurcated on right-hand bend one side and opposite, two tunnel bifurcateds can directly be turned right the right-hand bend vehicle and are not needed unnecessary detouring, the vehicle that leaves straight tunnel earth terminal can be striden across from the turn right ground, bifurcated section top in tunnel of opposite face, realize the multilevel traffic of through vehicles and opposite right-hand bend vehicle.
Five, prolongation track in the ground in right-hand bend tunnel strides across the craspedodrome tunnel and the right-hand bend tunnel of ground, right side by-path: right curved tunnel single file section is put near the ground plane in zone by the deep-seated that the right-hand bend direction directly arrives bifurcated in the same way " Y " the font fork tunnel on right side, its ground prolongs bifurcated in the same way " Y " the font fork tunnel multilevel traffic that track and this deep-seated are put the zone, and what just solved the straightgoing vehicle of the ground by-path that right-hand bend vehicle and right-hand bend will arrive and right-hand bend car intersects the road occupying collision problem.The right-hand bend vehicle does not detour, and has reduced unnecessary traffic conflict point.
Six, the right-hand bend Tunnel Design become right, dual-purpose tunnel turns left: the right-hand bend tunnel is not passed does not stride across bifurcated " Y " font fork tunnel in the same way, right side, and right-hand rotation tunnel earth terminal is communicated with the left turn lane of ground, right side by-path, and the right-hand bend tunnel just becomes the right side, dual-purpose tunnel turns left.And do not need two tunnels respectively as right, the use of turning left.
