Technical field
The utility model belongs to the tunnel that makes the right-angled intersection automobile traffic unimpeded, particularly four independently the bifurcated tunnel straightgoing vehicle) and left-hand bend motor vehicle (above abbreviation: the have no road occupying unimpeded combining structure in a plurality of tunnels of conflict left turning vehicle) 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 two road under 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 left-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 can not be built all; 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 the 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; Four " fore-telling " font bifurcated tunnels are combined into the conflict that has no road occupying of craspedodrome tunnel and left-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 utility model solve to intersect the design of road occupying conflict point and is: be divided into three kinds of conflict points to a plurality of conflict points of right-angled intersection plane traffic: 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 the direct lane and the left turn lane of arrival ground by-path.
Solve first kind, there is the technical scheme of road occupying conflict in the left turning vehicle tunnel on straightgoing vehicle tunnel and opposite: craspedodrome tunnel and left-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 relatively are separate; Make a craspedodrome tunnel after passing right-angled intersection; Stride across above going up the left-hand bend tunnel in " fore-telling " font bifurcated tunnel to ground from the opposite, solved direct lane and opposite the left 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 goes 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 left turn lane with the direct lane of arrival ground by-path and left 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 left-hand bend tunnel; Stride across above the bifurcated tunnel [craspedodrome tunnel and left-hand bend tunnel] of the ground by-path that arrives from this left-hand bend tunnel, solved left turn lane and the ground by-path of arrival direct lane and left turn lane intersect collision problem.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 left turn lane have been realized multilevel traffic fully, no longer include the road occupying conflict point.
The design of the new function of the utility model: take the ground and the underground space for reduce the utility model combination tunnel as far as possible; Traffic route fully can be identical left-hand bend tunnel and the right-hand bend tunnel of ground, left side, this left-hand bend tunnel by-path; The width that the left and right merging tunnel that goes with an ability rightabout, left and right commentaries on classics merge the tunnel can reduce the width about 5.0 meters than side by side two the independent left-hand bend tunnels and the overall width in right-hand bend 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 the combination tunnel takies ground and space but become the left-hand bend Tunnel Design left and right commentaries on classics to merge the tunnel.
The Figure of description of Chinese patent 200820230509.5 " direct left and right commentaries on classics 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 utility model 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 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 on bridge, only has only a point and produce the problem of traffic congestion.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, is the rule that ground level road is divided though merge the track section, does not belong to the structure content of the utility model, and the tunnel structure of the utility model 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 " direct left and right commentaries on classics 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, 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 on bridge, blocks up that causes with one together 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 traffic congestion problem that produces very little 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 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 utility model can reduce because of merging the too narrow traffic congestion problem that produces very little of track point at double.
The design of the utility model new construction:
One, the left-hand bend tunnel does not pass bifurcated " fore-tellings " font fork tunnel in the same way, left side: with independently four in the same way bifurcated " fore-telling " font pitch the tunnel; 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 in the same way the left-hand bend tunnel in bifurcated " fore-telling " font fork tunnel bifurcated in the same way " fore-tellings " font that do not pass, do not stride across the left side pitch the tunnel; But the left-hand bend tunnel is communicated with ground putting above the section near the deep-seated in bifurcated in the same way " fore-telling " font on left side fork tunnel; Not only make the vehicle on the left-hand bend tunnel can go up ground, stride across bifurcated in the same way " fore-telling " the font fork tunnel on the left side from ground, this left-hand bend tunnel is communicated with the right-turn lane of ground, left side by-path; Vehicle on this right-turn lane can be realized turning right with tunnel, the outside face in this tunnel that turns left, and becomes the dual-purpose tunnel of left and right commentaries on classics to this left-hand bend tunnel.
Two, with independently four in the same way bifurcated " fore-tellings " font pitch the tunnel; 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 left-hand bend tunnel in bifurcated " fore-telling " font fork tunnel with the opposite respectively in the same way.The shape of curved tunnel, left side 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 left-hand bend length of tunnel; Thereby reduced the left-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 require two of opposite face in the same way two craspedodrome tunnels of bifurcated " fore-telling " font fork tunnel rightabout driving separate, need not same tunnel; And vertical dislocation is arranged; Promptly the underground tunnel construction sections that goes out a tunnel construction sections straight tunnel earth terminal and a craspedodrome tunnel of 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 in left side, promptly let the left-hand bend tunnel on opposite directly go out curved tunnel, left side single file section, in addition the ground by-path position multilevel traffic at the parting of the ways of the left-hand bend tunnel of realizing craspedodrome tunnel and opposite at the side bifurcated that turns left for craspedodrome tunnel, opposite.Be positioned at the opposite in the same way among the branch prong in bifurcated " fore-telling " 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; Become straight tunnel single file section partly go out the tunnel section embed the opposite in the same way bifurcated " fore-tellings " font pitch the tunnel and divide the structure among the prong; But straight tunnel single file section is not passed curved tunnel, a left side, opposite single file section, makes the left 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 curved tunnel, left side single file section prolongs track and all becomes multilevel traffic with bifurcated in the same way " fore-tellings " the font fork tunnel of the ground by-path that turns left to be arrived, but curved tunnel, left side single file section is not passed with bifurcated in the same way " fore-telling " font of the ground by-path that arrived of turning left and pitched the tunnel.
The structure of the utility model is:
The combination tunnel in four independences of right lateral system length shape " fore-telling " font bifurcated tunnel; Comprise four bifurcated tunnels; It is characterized in that: all there are a craspedodrome tunnel 2 and a left-hand bend tunnel 3 in each bifurcated tunnel; Left-hand bend tunnel 3 is positioned at the left side in craspedodrome tunnel 2, and all at a side and craspedodrome tunnel 2 bifurcateds of turning left, this bifurcation is a bifurcation 15 in left-hand bend tunnel 3; Make a craspedodrome tunnel 2 and a left-hand bend tunnel 3 form " fore-telling " font bifurcated tunnel, then four bifurcated tunnels become four bifurcated " fore-telling " font fork tunnels 1 in the same way;
Each has with left-hand bend tunnel 3 and advances tunnel earth terminal 4 jointly in the craspedodrome tunnel 2 in bifurcated " fore-telling " font fork tunnel 1 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, left-hand bend tunnel 3 and craspedodrome tunnel 2 bifurcateds in the fork of bifurcated " fore-telling " font in the same way tunnel; Left-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 left-hand bend tunnel 3 also also has a left-hand rotation tunnel earth terminal 6; Earth terminal 5 is a straight tunnel single file section 8 to straight tunnel from bifurcation 15; Earth terminal 6 is curved tunnel, a left side single file section 13 to the left-hand rotation tunnel from bifurcation 15;
Divide prong relative two to form a grouping tunnel in bifurcated " fore-tellings " font fork tunnel 1 in the same way, four in the same way bifurcated " fore-telling " font pitch tunnel 1 and 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 " fore-telling " 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 " fore-telling " font fork tunnel 1, and the straight tunnel of brachmorphy single file section 8-2 is positioned at and belongs in the same way bifurcated " fore-tellings " font and pitch between the straight tunnel single file section 8 in tunnel 1 and another grouping tunnel; Pitch between the tunnel 1 in bifurcated in the same way " fore-tellings " font fork tunnel 1 and the left side that curved tunnel, left side single file section 13 is positioned at place bifurcated " fore-telling " font in the same way.
The design feature in the utility model left-hand bend tunnel 3 makes left-hand bend tunnel 3 become the shared tunnel of left and right commentaries on classics; Reduce the floor space of combination central area, tunnel: pitch between the tunnel 1 in bifurcated in the same way " fore-tellings " the font fork tunnel 1 that curved tunnel, left side single file section 13 is positioned at the place and left side bifurcated " fore-tellings " font in the same way, and the left side in the tunnel 3 that promptly turns left is bent bifurcated in the same way " fore-telling " font that tunnel single file section 13 do not pass, do not stride across 3 left sides, this left-hand bend tunnel and pitched tunnel 1.Left-hand rotation tunnel earth terminal 6 is communicated with the right-turn lane of the ground by-path in left side, and the right-hand bend car of ground, left side by-path can directly use as the right-hand bend tunnel with the outside in this left-hand bend tunnel 3, realizes turning right.The left-hand rotation car of just adjacent ground by-path and right-hand rotation car can reach the purpose of turning separately in shared left-hand bend tunnel 3; Be turn left car in the left-hand bend tunnel 3 lean on 8 one-tenth three-dimensional decussate textures of two groups of straight tunnel single file sections inboard tunnel faces, and the right-hand rotation car is at tunnel face in the outer part.Left-hand rotation car and the shared left-hand bend of right-hand rotation car tunnel 3 are realized and are turned right; Than realizing and turn right still less taking the ground and the underground space of crossroad with two tunnels in left-hand rotation tunnel and right-hand rotation tunnel; Become the more combination tunnel of miniaturization; Help to use this combination tunnel, also reduce the built tunnel expense in littler crossroad.
The keep straight on design feature in arch tunnel 2 of the utility model increases the length that merges the track and prevents traffic congestion: with independent discrete four in the same way bifurcated " fore-tellings " font pitch two grouping tunnels of 1 fen prong composition facing each other, tunnel; 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 " fore-telling " font fork tunnel 1; But do not stride across or do not pass opposite curved tunnel, the left side single file section 13 in bifurcated " fore-telling " font fork tunnel 1 in the same way, this grouping tunnel is two embedded grouping tunnels.The through vehicles that the straight tunnel earth terminal 5 of single file section 8 goes out the tunnel from straight tunnel like this is on ground; With from the left side in the same way the left-hand rotation tunnel earth terminal 6 in bifurcated " fore-telling " font fork 1 left-hand bend tunnel 3, tunnel go out the left-hand bend vehicle merging track of tunnel to ground; Promptly the through vehicles and the left-hand bend vehicle in bifurcated " fore-telling " 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 " fore-telling " font fork tunnel 1 is meant that left-hand bend tunnel 3 and craspedodrome tunnel 2 have one section side by side in the same way, and deep-seated has bifurcation 15 on the left of putting the zone but left-hand bend tunnel 3 is in the stage casing in craspedodrome tunnel 2.In near left-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.Left-hand bend tunnel 3 turns left to use as motor vehicles." in the same way " be meant that the left-hand bend tunnel 3 in each " fore-telling " font fork tunnel is all identical with the bifurcated direction in craspedodrome tunnel 2, i.e. each left-hand bend tunnel 3 bifurcated all, directly left-hand rotation with other any tunnel grade separation in the left side in craspedodrome tunnel 2.So one in the same way the global shape in bifurcated " fore-telling " font fork tunnel 1 be: a left-hand bend tunnel 3 and a craspedodrome tunnel 2 are side by side advancing tunnel earth terminal 4 jointly to bifurcation 15, and this section is two tunnels side by side sections 14 side by side.Craspedodrome tunnel 2 behind the bifurcated is a straight tunnel single file section 8, and the left-hand bend tunnel 3 behind the bifurcated is curved tunnel, a left side single file section 13.
The craspedodrome tunnel 2 in same bifurcated in the same way " fore-telling " font fork tunnel 1 and the tunnel earth terminal 4 that advances jointly in left-hand bend tunnel 3 can be zonules, and the tunnel 2 of then keeping straight on advances tunnel point and left-hand bend tunnel 3 advances the tunnel point in same area; In this same area, craspedodrome tunnel 2 enters tunnel point and left-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.
Left-hand bend tunnel 3 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 in left-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 left-hand bend tunnel 3 in same bifurcated in the same way " fore-telling " font fork tunnel 1 is preferably in the deep-seated that satisfies traffic specification with craspedodrome tunnel 2.
Left-hand rotation tunnel earth terminal 6 preferably is positioned near the ground the bifurcation 15 in bifurcated in the same way " fore-telling " font fork tunnel 1 of the ground by-path that left-hand bend will arrive; Curved tunnel, left side single file section 13 does not stride across, does not pass bifurcated in the same way " fore-tellings " the font fork tunnel 1 of the ground by-path that left-hand bend will arrive, and pitches tunnel 1 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 on ground and right side in the same way the through vehicles in bifurcated " fore-telling " 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 " fore-telling " font fork tunnel 1 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 in bifurcated " fore-telling " font fork tunnel 1 from left-hand rotation tunnel earth terminal 6 to ground after from it face stride across, thereby realize this bifurcated " fore-tellings " font fork tunnel 1 and left-hand bend vehicle ability multilevel traffic in the same way from the right side.
The grouping tunnel is by minute prong relative two combining structure in bifurcated " fore-telling " font fork tunnel 1 in the same way, and the straightgoing vehicle that goes as the rightabout of two ground by-paths of crossroad opposite face realizes keeping straight on and left turning vehicle is realized the combination tunnel of left-hand bend.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 regarded 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 near the opposite in the same way bifurcated " fore-tellings " font pitch the bifurcated section 7 top ground locations in tunnel 1, 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 left-hand bend tunnel 3: curved tunnel, the left side in left-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 curved tunnel, left side 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 a left side.This preferred structure makes the utility model can be used for having only more than 65 meters between place, diagonal angle, the crossroad building, and between the building of two-way six-lane both sides the crossroad of the above width in eight tracks is arranged, and can both build the unimpeded tunnel of combination of the utility model.This just makes the utility model can be used for the crossroad, arterial highway in old city, realizes that crossroad, the old arterial street straightgoing vehicle that people hope has no road occupying unimpeded with the commentaries on classics cart.
Curved tunnel, the left 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 curved tunnel, two arc left sides of stereo cross shape structure centre indent single file section 13 relative beeline length; The min. turning radius of curved tunnel, two arc left sides single file section 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, explains that the crossroad area is big more, and then turning radius R can be big more, and curved tunnel, 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 the present invention will solve so turn right.Turning right 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 the outside in left-hand bend tunnel 3 promptly be widened in the left side; The right-hand bend car that is used for ground, left side by-path uses, and the tunnel 3 that just turns left becomes the left turning vehicle of this ground by-path and the common dual-purpose tunnel that uses of right-hand bend car of ground, left side by-path.The structure in left-hand bend tunnel 3 has no variation; Just become 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 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 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 the overpass bridge design specifications; The minimum widith in the dual-purpose tunnel of left and right commentaries on classics of the utility model 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; And the whole combination of the utility model tunnel minimum takies 65.0 meters on the straight warp of the circle on ground, and the straight warp of circle that takies ground than the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge minimum has reduced by 10.0 meters width for 75.0 meters.This stand out of 10.0 meters; Make the combination tunnel of the 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 the combination tunnel of the utility model usability widely arranged than the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge; The combination tunnel of the 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.
What " left side " " right side " on the described left side of the utility model or the right, the left side or the right side, right side, left side was meant that the people stands in some bifurcateds in the same way " fore-telling " 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 " left side " or " right side ".
Described two tunnels of the utility model section 14 side by side comprise two tracks at least.
Described track of the utility model or tunnel are can pass through at least road or the tunnel of a motor vehicle, but described track or tunnel do not limit width, can increase width many cars side by side.
The described craspedodrome of the utility model tunnel 2 is meant that the travel direction of motor vehicles in the tunnel is to keep straight on to pass the tunnel of crossroad for purpose; But descending and upward slope that the level height meaning is arranged; So the shape in craspedodrome tunnel 2 can be rectilinear form or curved shape; When actual built tunnel, the shape in craspedodrome tunnel 2 is shaped as according to confirming with ground level road.
The described left-hand bend of the utility model tunnel 3 is meant and is used to turn left the tunnel that motor vehicles use.The left side bifurcated is put at the deep-seated in craspedodrome tunnel 2 in the left-hand rotation tunnel of right lateral system, and the direction that is directly turned left in left-hand bend tunnel 3 is turned, and does not need to do unnecessary detouring from ground, the right by-path and ground, opposite by-path.
The described left-hand bend of the utility model tunnel 3 can also can be used as the right-hand bend tunnel use of ground, 3 left side, this left-hand bend tunnel by-path only as turning left to use, and the tunnel 3 that promptly turns left can be the dual-purpose tunnel of left and right turning.
The described right lateral system of the utility model refers to the traffic administration system that motor vehicles are kept to the right.
The described intersection road occupying of the utility model conflict refers to the traffic conflict between the motor vehicles at the parting of the ways.
The described deep-seated of the utility model 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 utility model does not indicate.
The advantage of the utility model:
One, is divided into four small-sized " fore-telling " font tunnels to large-scale overpass bridge; Prevent the disaster 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 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 producing this overpass bridge and destroy; Cause whole large-scale overpass bridge not use, this crossroad access is paralysed fully.And the utility model is with four small-sized " fore-telling " 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 left-hand bend tunnel can be used as and the shared tunnel of turning right: the left-hand rotation tunnel earth terminal in left-hand bend tunnel is connected with the right-turn lane of ground, left side by-path, and the left-hand bend tunnel just can be used as the shared tunnel of right-hand bend car of ground, left side by-path.The minimum tunnel face width degree in the left-hand bend and the shared tunnel of turning right will reduce about 5.0 meters than the overall width with two separate tunnel in left-hand rotation tunnel and right-hand rotation 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.So; The circle that the whole combination of the utility model tunnel minimum takies the ground and the underground space is straight through 65.0 meters, and the straight warp of circle that takies ground and space than the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge minimum has reduced by 10.0 meters width for 75.0 meters.Then the combination tunnel of the utility model 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 above left tunnel turning tunnel pitched in bifurcated in the same way " fore-tellings " font on opposite, is striden across; With from the left side in the same way the left-hand bend tunnel in bifurcated " fore-telling " font fork tunnel go out the left-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 basically and do not have unnecessary detouring: it is unimpeded that two-way six-lane crossroad craspedodrome motorway and left-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 basically; Do not change direction of traffic and the custom of people, can not get lost because of detouring redundantly in the current process at the parting of the ways, practice thrift the built tunnel engineering cost in the usual friendship crossroad.
Five, the little crossroad of two-way six-lane can be used: the utility model is only used four combinations in bifurcated " fore-telling " 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; Reduced floor space and space in a large number, made it have only 65 meters two-way six-lane small size crossroad, city can realize that also grade separation is unimpeded, promptly do not intersected the road occupying conflict point at round diameter; 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 left turning vehicle multilevel traffic: no matter be the left-hand bend tunnel of striding the opposite on the through vehicles, stride the craspedodrome tunnel and the left-hand bend tunnel in left side on the vehicle that still turns left, all only use one deck tunnel.
The inventive point of the utility model 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 " direct left and right commentaries on classics interchange overpass " is a large-scale overpass bridge of integral body that is connected as a single entity, and connects as one whole overpass bridges of the various runways in crossroad.And the utility model is thought; From the tunnel of Different Ground by-path after through the crossroad; Tunnel unnecessary and from other ground by-path is connected, and more can realize merging the track with vehicle from the tunnel of other ground by-path, sails out of this crossroad; Also more be difficult for traffic congestion; So the utility model also comprises through not interconnecting behind the crossroad not interconnecting from the tunnel of Different Ground by-path, make four ground by-paths of crossroad use respectively four in the same way bifurcated " fore-tellings " font pitch 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 superior to Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass ".That is to say: from single comparison, the utility model is split as four small-sized " fore-telling " font tunnels to screen frame formula overpass bridge; From integral body relatively, the combination tunnel in four small-sized " fore-telling " 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 left-hand bend tunnel does not pass through each other: this craspedodrome tunnel does not stride across the left-hand bend tunnel on opposite, realizes keeping straight in the left-hand bend tunnel that just makes vehicle in the craspedodrome tunnel stride across the opposite from ground; And the left-hand bend tunnel does not stride across left side the craspedodrome tunnel and the left-hand bend tunnel in bifurcated " fore-telling " font fork tunnel in the same way, makes the vehicle in the left-hand bend tunnel stride across left side the craspedodrome tunnel and the left-hand bend tunnel in bifurcated " fore-telling " font fork tunnel in the same way from ground.This structure makes through vehicles and the left turning vehicle in different bifurcated in the same way " fore-telling " 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, move on to traffic conflict point away from the by-path position of crossroad and go multilevel traffic: the utility model is not the position that the road occupying conflict takes place to intersect traffic behavior on the plane; 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 the creationary by-path position, four ground that moves on to these two types of traffic conflict points away from the crossroad solves traffic conflict, thereby can take the ground and the underground width of crossroad minimumly.This unimpeded structure reduces the annular region area requirements of crossroad greatly.As long as between the building of ground by-path the above width in eight tracks is arranged; The unimpeded tunnel of combination that has ground and the underground space more than 65 meters just can build up the utility model 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 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 the tunnel earth terminal that advances jointly in bifurcated " fore-telling " 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 bifurcated " fore-tellings " the font deep-seated of pitching the 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 " fore-telling " font fork tunnel put the section leftward space; Let 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.
Five, the ground in left-hand bend tunnel prolongs craspedodrome tunnel and the left-hand bend tunnel that the track strides across ground, left side by-path: the deep-seated in bifurcated in the same way " fore-telling " the font fork tunnel on the left of curved tunnel, left side single file section directly arrives by the left-hand bend direction is put near the ground plane zone; Its ground prolongs the track and pitches the tunnel multilevel traffic with bifurcated in the same way " fore-tellings " font that this deep-seated is put the zone, just solved the ground by-path that left-hand bend vehicle and left-hand bend will arrive straightgoing vehicle and left turning vehicle intersect the road occupying collision problem.The left-hand bend vehicle does not detour, and has reduced unnecessary traffic conflict point.
Six, become the dual-purpose tunnel of left and right turning to the left-hand bend Tunnel Design: do not pass the left-hand bend tunnel and do not stride across bifurcated " fore-telling " font fork tunnel in the same way, left side; And left-hand rotation tunnel earth terminal is 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.
