Description
Technical field
The invention belongs to the overpass bridge making right-angled intersection automobile traffic unimpeded, particularly four independently Y-shaped arch bridge be combined into the craspedodrome motor vehicle of crossroad can be made to have no road occupying hereinafter referred to as: left turning vehicle hereinafter referred to as: straightgoing vehicle and left-hand bend motor vehicle multiple bridge smooth combination structures of conflict.
Background technology
At present, the traffic of international and domestic usual friendship crossroad, arterial street is very crowded, often blocks, and is each metropolitan common fault in the whole world.Tracing it to its cause, is that on crosspoint, two road overlap becomes a road, and the motor vehicles on two road can only share a road on node, have lost the path resource of half because two road usual friendship.Add the mixed row of pedestrian, bicycle and motor vehicle, the result that is inevitable of blocking up.In order to solve this difficult problem, people contemplate widening pavement, increase the quantity of crossing runway, but road surface infinitely can not be widened.People contemplate overpass bridge again, but in existing vertical civilian bridge design scheme, can make crossroad direct lane and left turn lane have no road occupying conflict overpass bridge minimum diameter more than 120 meters, not only build cost high, 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 some crossroads.
Chinese patent 200720043390.6 " the full unblocked overpass bridge of individual layer " discloses a kind of smooth combination structure associating bridge establishing a straight bridge and an annular bridge at the parting of the ways.Its shortcoming: driver must see clearly operation sign at the parting of the ways, once do not see clearly or see clearly rear oneself can not lane change, can cause blocking up at Ji Jin crossroad, lane change crosspoint place.---turning left,---the road k-path partition specification of---craspedodrome---right-hand rotation that the road k-path partition specification of right-hand rotation is different from existing left-hand rotation, this makes driver, and close to after this overpass bridge, oneself has little time lane change in craspedodrome from inside to outside.In a word,---turning left,---the road k-path partition specification of---craspedodrome---right-hand rotation that the road k-path partition specification of right-hand rotation is different from existing left-hand rotation, makes this overpass bridge can not apply on the road of existing specification in the craspedodrome from inside to outside that this overpass bridge requires.
Chinese patent 200820230509.5 is " directly left, right-hand rotation interchange overpass " disclose a kind of overpass bridge, due to claims of this patent and manual very unclear to the description of technical scheme, but just seem to understand the structure of this screen frame shape overpass bridge with Figure of description and defect is: one, add unwanted height and length: in the by-path position, ground away from crossroad, craspedodrome bridge is just connected with ground from continuing one section of pontic after the left-hand bend bridge on opposite passes beneath again, make the overhead highly very high of upper layer bridge, add the total length of bridge, make whole pontic not only high not only long but also large like this, waste bridge construction expense, block civic landscape.Two, local damage causes overall damage: after left-hand bend bridge passes beneath from the craspedodrome bridge of ground, left side by-path and left-hand bend bridge, be connected with ground again after flushing with the lower bridge section of the craspedodrome bridge of right ground by-path, also the overhead highly very high of upper layer bridge is made, add the total length of bridge, also making whole pontic connect is a large-scale integral bridge, once the local of this large-scale integral bridge has geology to change, its local damagedly just will cause whole large-scale integral bridge to damage.Three, whole bridge becomes screen frame shape area occupied too large: the global shape of overpass bridge is for there being two cornerwise screen frame shape pontics, require that crossroad does not have the circular minimum diameter in the vacant lot of building to be 115 meters, and in the two-way six-lane crossroad of old urban area, diameter reaches 115 meters almost not having, and the overpass bridge that namely this Figure of description provides almost can not be used for two-way six-lane crossroad, old urban area.
Summary of the invention
The object of this invention is to provide the road track arrangement meeting existing right line system traffic specification, can build in the small size crossroad of two-way six-lane, four " fore-telling " shaped forked bridges are combined into direct lane and left turn lane and have no road occupying conflict, and there is longer merging track section in the multiple tracks leaving crossroad and the many bridges combined type freely-moving bridge not easily blocked up.
The present invention solves and intersects the design of road occupying conflict point and be: multiple conflict points of right-angled intersection plane traffic are divided into three kinds of conflict points: the first is that the left turn lane on direct lane and opposite has road occupying conflict; The second be four direct lanes be divided into two groups at the parting of the ways central area have and intersect road occupying conflict; The third be left turn lane with this left-turning pathways arrive the direct lane of ground by-path and left turn lane and have and intersect road occupying and conflict.
Solve the first, the technical scheme that the left turn lane on direct lane and opposite has road occupying to conflict: the craspedodrome bridge on each ground by-path of right-angled intersection and left-hand bend bridge are one group, and the upper bridge end often organized all is connected with same ground by-path.Two craspedodrome bridges of relative craspedodrome are separate, make a craspedodrome bridge after striding across right-angled intersection, pass from the left-hand bend bridge of " fore-telling " shaped forked shape arch bridge on opposite through ground, solve the cross interference of the left turn lane on direct lane and opposite.This technical scheme solves four road occupying conflict points.
Solve the second, article four, direct lane be divided into two groups at the parting of the ways central area have and intersect the technical scheme of road occupying conflict: the direct lane travelled that intersects becomes multilevel traffic in centre at the parting of the ways, solves the traffic conflict problem of four direct lanes central area at the parting of the ways.This technical scheme solves four road occupying conflict points.
Solve the third, to be left turn lane with the direct lane of arrived ground by-path and left turn lane have intersects the technical scheme that road occupying conflicts: the track, ground leaving crossroad be communicated with the lower bridge end of left-hand bend bridge, from the passing beneath of Y-shaped arch bridge [craspedodrome bridge and left-hand bend bridge] of the ground by-path that this left-hand bend bridge arrives, solve the direct lane of ground by-path and the cross interference of left turn lane of left turn lane and arrival.This technical scheme solves eight road occupying conflict points.
Like this, the crossroad of plane traffic, four craspedodrome bridges and total 16 the road occupying conflict points of four left-hand bend bridges have been fully realized multilevel traffic, no longer include road occupying conflict point.
The design of New function of the present invention: the present invention not only will solve the driving route of crossroad without cross interference, also be provided in leave crossroad ground level road on have sufficiently long merging track section, solve and merge track on bridge, only produce the problem of traffic congestion at a point.The through vehicles of crossroad and left-hand bend vehicle not only will accomplish do not have road occupying conflict point, also will accomplish leaving from the through vehicles of Different Ground by-path, left-hand bend vehicle, right-hand bend vehicle merging track section ground, crossroad by-path having multiple merging tracks point.The present invention is located at ground merging track section, although merging track section is the rule that ground level road divides, does not belong to the structure content of overpass bridge of the present invention, and the structure of overpass bridge of the present invention can make ground by-path can obtain merging track section.And multiple pontics that the screen frame shape overpass bridge disclosed in Figure of description of Chinese patent 200820230509.5 " direct-left-and-right-turning interchange " can be regarded as leaving cross friendship center merge track at a point, make through vehicles, left-hand bend vehicle and right-hand bend vehicle on bridge, only have one to merge track point, this three tracks merge track point with one on overpass bridge, very easily cause the consequence blocked up on bridge.And the present invention carries out track merging with the merging track section that may be provided in ground certain length, can solve the traffic congestion problem produced because merging track point is too narrow from the vehicle on different pontic.So, the present invention not only can solve the through vehicles of Ge Tiao ground, crossroad by-path and left-hand bend vehicle has no road occupying unimpeded, can also solve when leaving crossroad from the vehicle on Different Ground by-path pontic on a ground by-path, there is very well-to-do ground as merging track section, the screen frame shape overpass bridge disclosed in Figure of description comparing Chinese patent 200820230509.5 only has merging track, a position, then the present invention can reduce the traffic congestion problem produced because merging track point is too narrow at double.
The design of new construction of the present invention: with independently four in the same way bifurcated " fore-tellings " font pitch bridge, point prong composition facing each other two grouping bridges, four craspedodrome arch bridges of two grouping bridges carry out multilevel traffic with the opposite left-hand bend bridge that bridge pitched in bifurcated " fore-telling " font in the same way in the by-path position, ground away from crossroad respectively.The shape of left curved bridge single file section is the arcuate structure becoming three-dimensional decussate texture central area indent to two groups of straight bridge single file sections of two grouping bridges, with the grade separation position of other bridge also at the ground by-path away from center, crossroad, extend left-hand bend bridge length, thus the bridge length decreasing left-hand bend bridge and need because of the gradient to take very large-area problem at the parting of the ways.This just requires that two craspedodrome arch bridges of two of opposite face bifurcated " fore-telling " font fork bridge rightabout drivings are in the same way separate, need not same bridge, and have longitudinal dislocation, namely the ground upper bridge section of the straight bridge earth terminal of the lower bridge section of a craspedodrome arch bridge and that craspedodrome arch bridge of opposite jointly rises and has spacing distance between bridge earth terminal and not in same position, the straight bridge earth terminal of lower bridge section of craspedodrome arch bridge is closer to center, crossroad, as long as straight bridge earth terminal is in the local ground face, high position, stage casing close to opposite craspedodrome arch bridge, just for the superjacent air space in left side abdicated by opposite craspedodrome arch bridge, namely the left-hand bend bridge on opposite is allowed directly to go out left curved bridge single file section at left-hand bend side bifurcated, the left-hand bend bridge realizing craspedodrome arch bridge and opposite at the parting of the ways beyond ground by-path on multilevel traffic.As long as bridge section is positioned among point prong of opposite bifurcated " fore-telling " font fork bridge in the same way under having the part of two in a grouping bridge straight bridge single file sections, under Cheng Zhiqiao single file section part bridge section embed opposite in the same way bifurcated " fore-tellings " font pitch bridge and divide structure among prong, but straight bridge single file section through the left curved bridge single file section in opposite, does not make the structure not having straight bridge single file Duan Ercheng one deck pontic below the curved bridge single file section of a left side for this position.Center at the parting of the ways, two groups of straight bridge single file sections of two grouping bridges become multilevel traffic.Away from the ground by-path at center, crossroad, the prolongation track, ground of each left side curved bridge single file section is pitched bridge with bifurcated in the same way " fore-telling " font of the ground by-path turning left to arrive and is become multilevel traffic, but left curved bridge single file section does not pitch bridge through bifurcated in the same way " fore-telling " font with the ground by-path turning left to arrive.Right-hand bend bridge in the outside of left-hand bend bridge directly with adjacent two in the same way bifurcated " fore-telling " font pitch that bridging is logical just can complete right-hand rotation function.
Structure of the present invention is:
Right-hand rotation is full unblocked cross composite bridge in the crossroad in outside, comprise four Y-shaped arch bridges, it is characterized in that: each Y-shaped arch bridge has a craspedodrome arch bridge 2 and a left-hand bend bridge 3, left-hand bend bridge 3 is positioned at the left side of craspedodrome arch bridge 2, left-hand bend bridge 3 is all at left-hand bend side and craspedodrome arch bridge 2 bifurcated, this bifurcation is bifurcation 15, make a craspedodrome arch bridge 2 and a left-hand bend bridge 3 form " fore-telling " shaped forked bridge, then four Y-shaped arch bridges become four bifurcated " fore-telling " font fork bridges 1 in the same way;
Craspedodrome arch bridge 2 and the left-hand bend bridge 3 of each bifurcated in the same way " fore-telling " font fork bridge 1 have a common bridge earth terminal 4, and the common two bridges section 14 side by side risen between bridge earth terminal 4 to bifurcation 15; In the fork of bifurcated " fore-telling " font in the same way region, high position, bridge 1 stage casing, left-hand bend bridge 3 and craspedodrome arch bridge 2 bifurcated; The region, high position that left-hand bend bridge 3 leaves craspedodrome arch bridge 2 is bifurcated section 7; Craspedodrome arch bridge 2 also has a straight bridge earth terminal 5, and left-hand bend bridge 3 also also has a left-hand rotation bridge earth terminal 6; Be straight bridge single file section 8 from bifurcation 15 to straight bridge earth terminal 5; It is left curved bridge single file section 13 from bifurcation 15 to left-hand rotation bridge earth terminal 6;
Point prong relative two in the same way bifurcated " fore-tellings " font fork bridge 1 forms a grouping bridge, four in the same way bifurcated " fore-telling " font pitch bridge 1 and form two grouping bridges respectively; Two groups of straight bridge single file sections, 8 one-tenth three-dimensional decussate textures of two grouping bridges; In same grouping bridge, straight bridge single file section 8 is positioned among point prong of opposite bifurcated " fore-telling " font fork bridge 1 in the same way, and this grouping bridge becomes a dual damascene formula grouping bridge; Bifurcated in the same way " fore-tellings " font that left curved bridge single file section 13 is positioned at place pitch bridge 1 and left side in the same way bifurcated " fore-telling " font pitch between bridge 1;
Also comprise four right-hand bend bridges 16, each bifurcated in the same way " fore-telling " font fork bridge 1 has a right-hand bend bridge 16, and the two ends of each right-hand bend bridge 16 are respectively right-hand bend divergent ends 17 and turn right and arrive end 18; The right-hand bend divergent ends 17 of right-hand bend bridge 16 is communicated with this right side that the craspedodrome arch bridge 2 high position section of bridge 1 pitched in bifurcated " fore-telling " font in the same way; Turn right and arrive end 18 and in the same way bifurcated " fore-telling " font and to pitch on the right side of bridge 1 on the left of left-hand bend bridge 3 that bifurcated " fore-telling " font in the same way pitches bridge 1 and be communicated with; Right-hand bend bridge 16 is positioned at the outside of left-hand bend bridge 3, is namely positioned at the left side of left-hand bend bridge 3.
The technique effect that design feature of the present invention and preventing accordingly blocks up: with independent discrete four bifurcated " fore-tellings " font fork bridge 1 point of prong composition facing each other two grouping bridges in the same way, straight bridge single file section 8 form of structure of two grouping bridges: the partial sector of each straight bridge single file section 8 of two grouping bridges is positioned among point prong of opposite bifurcated " fore-telling " font fork bridge 1 in the same way, but not through or do not stride across opposite in the same way bifurcated " fore-tellings " font pitch a left side curved bridge single file section 13 of bridge 1, this grouping bridge is dual damascene formula grouping bridge.Like this from the through vehicles of straight bridge earth terminal 5 bridges of straight bridge single file section 8 on ground, with from left side in the same way bifurcated " fore-telling " font pitch turn left left-hand rotation bridge earth terminal 6 times bridges of bridge 3 of bridge 1 and merge track to the left-hand bend vehicle on ground, namely from two in the same way bifurcated " fore-telling " the font fork through vehicles of bridge 1 and left-hand bend vehicle in merging track, ground, then can merge track at a longer section in track, ground, instead of be only confined to one and merge track point, the too narrow very little and traffic congestion problem that causes in site because merging track can be solved like this.In addition, right-hand bend vehicle from craspedodrome arch bridge 2 and left-hand bend bridge 3 jointly bridge earth terminal 4 just reach ground, meet to avoid merge track with the straightgoing vehicle of other ground by-path and left turning vehicle under very narrow bridge, reduce the problem of traffic congestion.
Bifurcated " fore-telling " font fork bridge 1 refers to that left-hand bend bridge 3 and craspedodrome arch bridge 2 have one section side by side in the same way, but left-hand bend bridge 3 has bifurcation 15 on the left of the region, high position, stage casing of craspedodrome arch bridge 2.Left-hand bend bridge 3 near bifurcation 15 and craspedodrome arch bridge 2 section preferably have more than the 4.5 meters clear height of closing symbol traffic specification, make below it by motor vehicles.Left-hand bend bridge 3 turns left to use as motor vehicles." in the same way " refer to that the left-hand bend bridge 3 of each " fore-telling " font fork bridge is identical with the bifurcated direction of craspedodrome arch bridge 2, namely each left-hand bend bridge 3 is at the left side bifurcated of craspedodrome arch bridge 2, not any pontic grade separation and directly turning left with other.So the global shape of bifurcated " fore-telling " font fork bridge 1 is in the same way: to play bridge earth terminal 4 to bifurcation 15 be side by side common for a left-hand bend bridge 3 and craspedodrome arch bridge 2, this side by side section be two bridges sections 14 side by side.Craspedodrome arch bridge 2 after bifurcated is straight bridge single file section 8, and the left-hand bend bridge 3 after bifurcated is left curved bridge single file section 13.
It can be a zonule that the same craspedodrome arch bridge 2 of bifurcated in the same way " fore-telling " font fork bridge 1 and the common of left-hand bend bridge 3 play bridge earth terminal 4, then craspedodrome arch bridge 2 bridge points and left-hand bend bridge 3 bridge points are in same area; In this same area, craspedodrome arch bridge 2 bridge points and left-hand bend bridge 3 bridge points can be same positions, or have certain longitudinal separation.
Craspedodrome arch bridge 2 is for the current bridge of two ground by-paths of crossroad opposite face, and " craspedodrome " refers to that motor vehicles arrive the meaning of opposite, crossroad road, and " craspedodrome " does not refer to the shape of bridge, and refers to the purposes of bridge.
Left-hand bend bridge 3 is the left-hand bend bridges for crossroad right-hand traffic system, and " left-hand bend " is purposes is the meaning of turning left.
The bifurcated section 7 of left-hand bend bridge 3 be for the motor vehicles of the craspedodrome arch bridge 2 from opposite from ground through current bridge section, motor vehicles are had to pass the height of needs below the height demand fulfillment of bifurcated section 7, so the left-hand bend bridge 3 of same bifurcated in the same way " fore-telling " font fork bridge 1 is preferably meeting region, the high position bifurcated of traffic specification with craspedodrome arch bridge 2.
Left-hand rotation bridge earth terminal 6 is preferably positioned at the ground near the bifurcation 15 of bifurcated in the same way " fore-telling " the font fork bridge 1 of the ground by-path turning left will arrive, left curved bridge single file section 13 is not passed, do not stride across bifurcated in the same way " fore-telling " the font fork bridge 1 of the ground by-path turning left will arrive, so that the motor vehicles that turn left pass bifurcated in the same way " fore-telling " the font fork bridge 1 of arrived ground by-path from ground.Left-hand bend motor vehicles on ground and right side in the same way bifurcated " fore-telling " font pitch bridge 1 arch bridge 2 times through vehicles to ground of keeping straight on and merge track, longer ground, merging track section can be had, instead of only have one to merge track point.Avoid the screen frame shape overpass bridge disclosed in Chinese patent 200820230509.5 Figure of description, make the through vehicles on left-hand bend vehicle and right ground by-path in the merging track, pontic position of two bridges, but the too narrow and traffic congestion problem that produces of the bridge floor merging track point.
The stage casing of bifurcated " fore-telling " font fork bridge 1 is provided with region, high position in the same way, to pass beneath from it after left-hand rotation bridge earth terminal 6 to ground from the left-hand bend vehicle of right side bifurcated " fore-telling " font fork bridge 1 in the same way, thus to realize this bifurcated " fore-tellings " font fork bridge 1 and left-hand bend vehicle energy multilevel traffic from right side in the same way.
Grouping bridge be by point prong relative two in the same way bifurcated " fore-tellings " font pitch the combining structure of bridge 1, the straightgoing vehicle that the rightabout as two ground by-paths of crossroad opposite face travels realizes keeping straight on and the composite bridge of left turning vehicle realization left-hand bend.A crossroad needs two grouping bridges, two groups of straight bridge single file sections, 8 one-tenth three-dimensional decussate textures of two grouping bridges.
" cross " meaning of two groups of straight bridge single file sections, 8 one-tenth three-dimensional decussate textures of two grouping bridges does not limit two groups of straight bridge single file sections 8 intersection in an angle of 90 degrees mutually of two grouping bridges, here " cross " is identical with " cross " implication of crossroad, namely " cross " makes a general reference Liang Tiao road intersection, does not limit intersecting angle.So, if straight bridge single file section 8 has to bend also still two of two grouping bridges groups of straight bridge single file sections 8 are considered as decussate texture.The shape of stereo cross shape structure refers to top view above decussate texture, two groups of straight bridge single file sections, 8 one-tenth three-dimensional decussate textures of two grouping bridges, but two groups of straight bridge single file sections 8 up and down of two grouping bridges are not connected, and have upper and lower space length, and it is current to meet motor vehicles.
Right-hand bend divergent ends 17 is preferably communicated with this right side that the bifurcation 15 of bridge 1 pitch in bifurcated " fore-tellings " font in the same way, so as to meet right side in the same way bifurcated " fore-telling " font pitch vehicle that bridge 1 turns left on bridge earth terminal 6 and can pass originally bifurcated " fore-telling " font in the same way from ground and pitch bridge 1.Turn right and arrive end 18 and preferably to pitch with in the same way bifurcated " fore-telling " font on the right side of bridge 1 on the left of bifurcated section 7 that bifurcated " fore-telling " font in the same way pitches bridge 1 and be communicated with.That is, right-hand bend bridge 16 can become levels structure on the left curved bridge single file section 13 of part of right side bifurcated " fore-telling " font fork bridge 1 in the same way, and also can misplacing, both become single layer structure.Each right-hand bend bridge 16 is respectively above the outside of a left-hand bend bridge 3, and preferably the inside edge of right-hand bend bridge 16 is close to above the outer ledge of left-hand bend bridge 3, to turn right, bridge 16 and left-hand bend bridge 3 reduce the space taken at the parting of the ways, when the turning radius of left-hand bend bridge 3 is 15.0 meters, the outside minimum range of opposite face two right-hand bend bridges 16 can only have 80.0 meters.80.0 meters of distances are had between the building of that is crossroad diagonal plane, just can build composite bridge of the present invention, the craspedodrome of this crossroad, left-hand rotation, right-hand rotation rolling stock is made to have no road occupying unimpeded, and can pass through arbitrarily bicycle and the pedestrian of crossroad.
The optimum position of right-hand bend divergent ends 17: straight bridge single file section from bifurcation 15 to stereo cross shape structure segment 8 is the straight bridge single file section of upward slope 19 again, the straight bridge single file that bridge 1 pitched in the right-hand bend divergent ends 17 of right-hand bend bridge 16 and in the same way bifurcated " fore-telling " font is communicated with on the right side of the section of upward slope 19 again.Like this, ensureing, under the condition that the right-hand bend bridge 16 bridge gradient needs, the length of right-hand bend bridge 16 to be reduced as far as possible, take the length close to ground, crossroad by-path less.
The optimum position of straight bridge earth terminal 5: be positioned at ground location below the bifurcated section 7 close to opposite bifurcated " fore-telling " font fork bridge 1 in the same way for straight bridge earth terminal 5 optimum position of dual damascene formula grouping bridge straight bridge single file section 8.Make its through vehicles can pass bifurcated section 7 from ground, then the height of bifurcated section 7 can reduce as far as possible, as long as the height of i.e. one deck bridge.
The preferred structure of left-hand bend bridge 3 a: the left side curved bridge single file section 13 of left-hand bend bridge 3 is preferably to the arcuate structure of two groups of straight bridge single file section 8 one-tenth three-dimensional decussate texture central area indents of two grouping bridges.In order to extend the length of left curved bridge single file section 13 and meet the gradient and meet traffic specification requirement, and take ground, crossroad or locus less as far as possible, and the turn fractions of curved for left side bridge single file section 13 is arranged to the arcuate structure that concaves.This preferred structure makes the present invention can be used for only having more than 65.0-80.0 rice between diagonal angle, crossroad place building, and has the small-sized crossroad of the eight above width in track between the building of two-way six-lane both sides, can build combination freely-moving bridge of the present invention.This just makes the present invention can be used for the crossroad, arterial highway in old city, realizes old arterial street crossroad straightgoing vehicle that people wish and left-hand rotation car has no road occupying unimpeded.
Concave a left side curved bridge single file section 13 min. turning radius design of arc: centered by the central point of two of two grouping bridges groups of straight bridge single file sections, 8 one-tenth three-dimensional decussate textures, same grouping bridge is L to the relative beeline length of the left curved bridge single file section 13 of two arcs of stereo cross shape structure centre indent, the min. turning radius of two left curved bridge single file sections 13 of arc 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 longer, and illustrate that crossroad area is larger, then turning radius R can be larger, and the left curved bridge single file section 13 of arc can bear the faster travel speed of motor vehicle.
" left side " " right side " on the right side of the left side of the present invention or the right, the left side or the right side, left side refers to that people stands in the common of some bifurcated in the same way " fore-telling " fonts fork bridge 1 and plays bridge earth terminal 4 position, in the face of the stereo cross shape structure centre of two groups of straight bridge single file sections 8 compositions of two grouping bridges goes to judge " left side " or " right side ".
Two bridges of the present invention side by side section 14 at least comprise two tracks.
Track of the present invention or bridge are at least can the pass through road of a motor vehicle or bridge, but described track or bridge do not limit width, can increase width many cars side by side.
Craspedodrome arch bridge 2 of the present invention refers to that the travel direction of motor vehicles on bridge is the bridge striding across crossroad for the purpose of keeping straight on, but there is the ascents and descents of level height meaning, so the shape of craspedodrome arch bridge 2 can be rectilinear form or curved shape, when actual bridge construction, the shape of craspedodrome arch bridge 2 with the shape of ground level road for according to determining.
Left-hand bend bridge 3 of the present invention refers to the bridge used for the motor vehicles that turn left.Left-hand rotation bridge bifurcated on the left of the high position of craspedodrome arch bridge 2 of right line system, makes left-hand bend bridge 3 turn directly to the direction of turning left, need not do unnecessary detouring from ground, the right by-path and ground, opposite by-path.
Right line system of the present invention, refers to the traffic administration system that motor vehicles are kept to the right.
Intersection road occupying conflict of the present invention refers to the traffic conflict at the parting of the ways between motor vehicles.
Can be passed through below region, high position of the present invention refers to the pontic section of motor vehicles height.
It is that bicycle " car " or " vehicle " refer to motor vehicle or refer to motor vehicles that the present invention does not indicate.
Advantage of the present invention:
One, the vehicle leaving crossroad has wider ground as merging track section: from the straight bridge earth terminal of straight bridge single file section, the through vehicles of bridge is kept straight on ground and passed beneath from bifurcated in the same way " fore-telling " the font fork bridge left-hand bend bridge on opposite, with from left side in the same way bifurcated " fore-telling " font pitch bridge under the left-hand bend bridge of bridge and merge track to the left-hand bend vehicle on ground, then can merge track at longer ground section, the screen frame shape overpass bridge disclosed in Figure of description avoiding Chinese patent 200820230509.5 merges the too little too narrow and traffic congestion problem that causes of lane position.
Two, be substantially same as the former circuit of plane traffic and detour without unnecessary: two-way six-lane crossroad craspedodrome motorway and the motor-driven road of left turning vehicle can be made to have no road occupying unimpeded, solve produce because of two road usual friendship at the parting of the ways traffic congestion, block the traffic problem.This is that one does not have the unnecessary circuit that detours, motor vehicles only have ascents and descents to be different from plane traffic at the parting of the ways, and driving route is same as the existing driving route had on the surface road of traffic lights substantially, do not change the direction of traffic of people in usual friendship crossroad and custom, can not because unnecessary detours and gets lost in current process at the parting of the ways, the engineering quantity of building bridge is in addition less than existing any intercommunicated overpass, saves bridge construction engineering cost.
Three, the less crossroad of two-way six-lane can be used: the present invention only uses the combination of four " fore-telling " shaped forked shape arch bridges in the same way, just achieve crossroad have no road occupying conflict completely unimpeded, the length of bridge is substantially reduce the number than the existing intercommunicated overpass detoured, substantially reduce the number floor space and space, the building minimum range at its diagonal angle is at the parting of the ways made to be that the two-way six-lane in city of 80.0 meters also can realize grade separation compared with small size crossroad unimpeded, namely road occupying conflict point is not intersected, weaving section is not had yet, new design scheme is provided for solving global arterial street automobile traffic congestion problems.
Four, composite bridge Xia Kehai road is in pedestrian: this patent is used for crossroad, and the ground of crossroad can allow pedestrian and non motorized vehicle arbitrarily to pass through, and does not have motor vehicle to disturb, and the non-separation of the machine that realizes, goes back in the people.
Inventive point of the present invention is:
One, the pontic of craspedodrome bridge and left-hand bend bridge does not pass through mutually: this craspedodrome bridge does not pass, do not stride across the left-hand bend bridge on opposite, just makes the vehicle on craspedodrome bridge realize keeping straight on from ground through the left-hand bend bridge on opposite; And turn left bridge not through, do not stride across left side bifurcated " fore-tellings " the font fork craspedodrome bridge of bridge and left-hand bend bridge in the same way, make the vehicle on left-hand bend bridge from ground through left side in the same way bifurcated " fore-telling " font pitch craspedodrome bridge and the left-hand bend bridge of bridge.This structure makes the through vehicles on different bifurcated in the same way " fore-telling " font fork bridges and left turning vehicle realize on ground merging track, as long as just can there be the merging track section of longer distance in merging track, ground, not easily too little too narrow and block up because merging track, the screen frame shape overpass bridge disclosed in Figure of description overcoming Chinese patent 200820230509.5 " direct-left-and-right-turning interchange " merges track and only has one merge site, track and easily produce the problem of traffic congestion on overpass bridge.
Two, the pontic of craspedodrome bridge and left-hand bend bridge does not pass through mutually: this craspedodrome bridge does not pass, do not stride across the left-hand bend bridge on opposite, just makes the vehicle on craspedodrome bridge realize keeping straight on from ground through the left-hand bend bridge on opposite; And turn left bridge not through, do not stride across left side bifurcated " fore-tellings " the font fork craspedodrome bridge of bridge and left-hand bend bridge in the same way, make the vehicle on left-hand bend bridge from ground through left side in the same way bifurcated " fore-telling " font pitch craspedodrome bridge and the left-hand bend bridge of bridge.This structure makes the through vehicles on different bifurcated in the same way " fore-telling " font fork bridges and left turning vehicle realize on ground merging track, as long as just can there be the merging track section of longer distance in merging track, ground, not easily too little too narrow and block up because merging track, the screen frame shape overpass bridge disclosed in Figure of description overcoming Chinese patent 200820230509.5 " direct-left-and-right-turning interchange " merges track and only has one merge site, track and easily produce the problem of traffic congestion on overpass bridge.
Three, multilevel traffic is gone in the by-path position that traffic conflict point moves on to away from crossroad: the present invention is not the position that intersection road occupying conflict occurs at plane traffic behavior, namely the position not at the parting of the ways in scope solves direct lane and left turn lane and intersects road occupying conflict, but creationary this kind of traffic conflict point is moved on to away from crossroad four ground by-paths on the conflict of multilevel traffic transport solution, thus minimal can take ground and the space of crossroad.This unimpeded structure requires greatly to reduce to the annular region floor area of crossroad.As long as there are eight lane widths between the building of ground by-path, combination freely-moving bridge of the present invention just can be built up with the ground of crossroad diameter more than 80 meters, the crossroad access realizing old city six-lane is unimpeded, has initiative meaning for solving the little crossroad access blocking in old urban area.
Four, on the ground by-path on two opposites, the left-hand bend bridge on the Xia Chuan opposite, prolongation track, ground of craspedodrome bridge: two two-way craspedodrome arch bridges of craspedodrome and rightabout craspedodrome relatively, separate, shared bridge; Namely straight bridge earth terminal than opposite in the same way the common of bifurcated " fore-telling " font fork bridge play the stereo cross crossing center of bridge earth terminal closer to two groups of craspedodrome arch bridges of two grouping bridges; Straight bridge earth terminal close to opposite in the same way bifurcated " fore-telling " font fork bridge region, high position before ground connection, so straight bridge earth terminal leave opposite in the same way bifurcated " fore-telling " font fork bridge on the left of space, high position, allow the left side on opposite curved bridge single file section can directly at the craspedodrome arch bridge bifurcated on left-hand bend side and opposite, two bridge bifurcateds make left-hand bend vehicle directly can turn left and not need unnecessary detouring, can make again to leave straight bridge earth terminal vehicle can from opposite face turn left bridge bifurcated section below ground pass, realize the multilevel traffic of through vehicles and opposite left-hand bend vehicle.
Wear craspedodrome bridge and the left-hand bend bridge of ground, left side by-path under the prolongation track, ground of five, left-hand bend bridge: craspedodrome bridge and the left-hand bend bridge of wearing ground, left side by-path under the prolongation track, ground of left-hand bend bridge: left curved bridge single file section pitch the high position areas adjacent of bridge by bifurcated in the same way " fore-tellings " font that left-hand bend direction directly arrives left side before ground connection, bridge multilevel traffic pitched in bifurcated in the same way " fore-telling " font in its prolongation track, ground and this region, high position, and what just solve left-hand bend vehicle and the straightgoing vehicle of ground by-path turning left will arrive and left turning vehicle intersects road occupying collision problem.Left-hand bend vehicle does not detour, and decreases unnecessary traffic conflict point.
