Abstract

The utility model relates to two crossroad full unlocked cross composite bridges of right turn bridges, which is a multi-bridge smooth composite structure formed by four independent bifurcation arch bridges for a crossroad. Each bifurcation arch bridge comprises a straight going arc bridge and a left turn bridge. The left turn bridge is located on the left side of the straight going arc bridge. The left turn bridge is bifurcated from the straight going arch bridge on a left turn side and forms a 'T'-shaped bifurcation bridge. Four bifurcation arch bridges are four 'T'-shaped bifurcation bridges bifurcating in the same direction. Two 'T'-shaped bifurcation bridges bifurcating in the same direction form a grouping bridge, and one-way sections of two groups of straight going bridges of the two grouping bridges form a three-dimensional cross structure. The crossroad full unblocked cross composite bridge has the advantages of reducing disaster degree of local geological change on the whole composite bridge, the left turn bridge can serve as a shared bridge for left turn and right turn, a wider ground surface is utilized as a merging lane section so as not to be easy to be caught in a traffic, vehicles can turn left directly without detour, pedestrian can walk under the composite bridge, and small crossroads of bidirectional lanes are completely unblocked.

Description

The full unblocked cross composite bridge in the crossroad of two kinds of right-hand rotation bridges
Technical field
The utility model belongs to the overpass bridge that makes the right-angled intersection automobile traffic unimpeded, particularly four independently the Y-shaped arch bridge be combined into the craspedodrome motor vehicle that can make the crossroad (hereinafter to be referred as: straightgoing vehicle) and the left-hand bend motor vehicle (hereinafter to be referred as the have no road occupying unimpeded combining structure of a plurality of bridges of conflict left turning vehicle).
Background technology
At present, the traffic of international and domestic usual friendship crossroad, arterial street is very crowded, often stops up, and is each metropolitan common fault of the whole world.Tracing it to its cause, is because the two road usual friendship, and on the crosspoint, two road are overlapping to have become a road, and the motor vehicles on the two road can only a shared road on node, has lost the path resource of half.Add pedestrian, bicycle and motor vehicle and mix row, the result that is inevitable blocks up.In order to solve this difficult problem, people have expected widening the road surface, increase the quantity of crossing runway, but the road surface can not be widened infinitely.People have expected overpass bridge again, but in existing upright civilian bridge design scheme, can make crossroad direct lane and left turn lane have no road occupying the conflict the overpass bridge minimum diameter more than 120 meters, not only build the cost height, and the crossroad of the two-way six-lane in old urban area all can not be built, make the crossroad traffic congestion of present old urban area very serious, the frequent traffic paralysis in the crossroad that has.
Chinese patent 200720043390.6 " the full unblocked overpass bridge of individual layer " discloses a kind of unimpeded combining structure associating bridge of directly striding a bridge and an annular bridge of establishing at the parting of the ways.Its shortcoming: the driver must see clearly operation sign at the parting of the ways, and oneself can not lane change in case do not see or see clearly the back clearly, can cause promptly advancing in the lane change crosspoint traffic congestion of place, crossroad.----the road division standard of turning right is different from the road of existing left-hand rotation--craspedodrome---right-hand rotation and divides standard, and oneself had little time lane change after this made the driver near this overpass bridge in left-hand rotation in craspedodrome from inside to outside.In a word,----the road division standard of turning right is different from the road that has--craspedodrome---right-hand rotation now and divides standard, and this overpass bridge can not be used on the road that has standard now in left-hand rotation in the craspedodrome from inside to outside that this overpass bridge requires.
Chinese patent 200820230509.5 is " directly left, the right-hand rotation interchange overpass " a kind of overpass bridge disclosed, because the claims and the manual of this patent are very unclear to the description of technical scheme, but as if just structure and the defective that can understand this screen frame shape overpass bridge with Figure of description is: one, unwanted height and length have been increased: in by-path position, ground away from the crossroad, continuing one section pontic after the craspedodrome bridge passes below the left-hand bend bridge on opposite more just is connected with ground, make the overhead highly very high of upper layer bridge, increased the total length of bridge, make whole pontic not only high not only long but also big like this, waste bridge construction expense has been blocked civic landscape.Two, local damage causes whole the damage: after the left-hand bend bridge passes below the craspedodrome bridge of ground, left side by-path and left-hand bend bridge, with be connected with ground again after the lower bridge section of the craspedodrome bridge of ground, right side by-path flushes, also make the overhead highly very high of upper layer bridge, increased the total length of bridge, also make whole pontics be connected to a large-scale integral bridge, once the part of this large-scale integral bridge has geology to change, its part is damaged and just will causes whole large-scale integral bridges to damage.Three, whole bridge becomes screen frame shape area occupied too big: the global shape of overpass bridge is for there being two cornerwise screen frame shape pontics, requiring the crossroad not have the circular minimum diameter in vacant lot of building is 115 meters, and in the two-way six-lane crossroad of old urban area, diameter reaches 115 meters almost not having, and just the overpass bridge that provides of this Figure of description almost can not be used for two-way six-lane crossroad, old urban area.
Summary of the invention
The purpose of this utility model provides the road track that meets existing right lateral system traffic specification and arranges, small size crossroad at two-way six-lane can be built, four " fore-telling " font bifurcated bridges are combined into the conflict that has no road occupying of direct lane and left turn lane, and there is long merging track section in a plurality of tracks of leaving the crossroad and is difficult for many bridges combined type freely-moving bridge of traffic congestion.
The utility model solve to intersect the design of road occupying conflict point and is: a plurality of conflict points of right-angled intersection plane traffic are divided into three kinds of conflict points: first kind is that the left turn lane on direct lane and opposite has the road occupying conflict; Second kind be four direct lanes be divided into two groups at the parting of the ways the central area have and intersect the road occupying conflict; The third is that the left turn lane has the road occupying of intersection to conflict with direct lane and the left turn lane that this left-turning pathways arrives the ground by-path.
Solve first kind, there is the technical scheme of road occupying conflict the left turn lane on direct lane and opposite: craspedodrome bridge and left-hand bend bridge on each ground by-path of right-angled intersection are one group, and every group last bridge end all is connected with same ground by-path.Two craspedodrome bridges of keeping straight on are separate relatively, make a craspedodrome bridge after striding across right-angled intersection, pass under the left-hand bend bridge of " fore-telling " font Y-shaped arch bridge on opposite through ground, solved direct lane and opposite the left turn lane intersect collision problem.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: the direct lane that travels that intersects becomes multilevel traffic in the centre at the parting of the ways, has solved four direct lanes traffic conflict problem of central area at the parting of the ways.This technical scheme has solved four road occupying conflict points.
Solve the third, to be the left turn lane with the direct lane of arrival ground by-path and left turn lane have intersects the technical scheme of road occupying conflict: the track, ground of leaving the crossroad that is communicated with the following bridge end of left-hand bend bridge, pass below the Y-shaped arch bridge [craspedodrome bridge and left-hand bend bridge] of the ground by-path that arrives from this left-hand bend bridge, solved the collision problem that intersects of the direct lane of left turn lane and the ground by-path of arrival and left turn lane.This technical scheme has solved eight road occupying conflict points.
Like this, the crossroad of plane traffic, four craspedodrome bridges and four 16 total road occupying conflict points of left-hand bend bridge have been realized multilevel traffic fully, no longer include the road occupying conflict point.
The design of the utility model new construction: with independently four in the same way bifurcated " fore-tellings " font pitch bridge, divide prong composition facing each other two grouping bridges, four craspedodrome arch bridges of two grouping bridges respectively with the opposite in the same way the left-hand bend bridge of bifurcated " fore-telling " font fork bridge carry out multilevel traffic in by-path position, ground away from the crossroad, the shape of the curved bridge single file section in a left side is the arcuate structure that becomes 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 ground by-path away from the center, crossroad, prolonged left-hand bend bridge length, will take very large-area problem at the parting of the ways because of the bridge length that the gradient needs thereby reduced the left-hand bend bridge.This just requires two of opposite face, and two craspedodrome arch bridges of bifurcated " fore-telling " font fork bridge rightabout driving are separate in the same way, need not same bridge, and vertical dislocation is arranged, promptly 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 rises jointly and between the bridge earth terminal spacing distance is arranged and not in same position, the straight bridge earth terminal of the lower bridge section of craspedodrome arch bridge is more near the center, crossroad, straight bridge earth terminal if before near the zone, high position, stage casing of opposite craspedodrome arch bridge ground plane, just abdicate the superjacent air space in left side for opposite craspedodrome arch bridge, promptly allow the left-hand bend bridge on opposite directly go out the curved bridge single file section in a left side, the multilevel traffic in addition the ground by-path at the parting of the ways of the left-hand bend bridge of realizing craspedodrome arch bridge and opposite at the side bifurcated that turns left.As long as there is bridge section under the part of two straight bridge single file sections in the grouping bridge to be positioned at the opposite in the same way among the branch prong of bifurcated " fore-telling " font fork bridge, Cheng Zhiqiao single file section partly descend the bridge section embed the opposite in the same way bifurcated " fore-tellings " font pitch bridge and divide structure among the prong, but straight bridge single file section is not passed and is not striden across the curved bridge single file section in a left side, opposite, makes the structure that does not have straight bridge single file section below the curved bridge single file section in a left side of this position and be one deck pontic.Center at the parting of the ways, two groups of straight bridge single file sections of two grouping bridges become multilevel traffic.On ground by-path away from the center, crossroad, ground of each curved bridge single file section in a left side prolongs track and all becomes multilevel traffic with bifurcated in the same way " fore-tellings " the font fork bridge of the ground by-path that turns left to be arrived, but the curved bridge single file section in a left side is not passed bifurcated in the same way " fore-telling " font that does not stride across the ground by-path that left-hand bend arrives and pitched bridge.One group of right-hand bend bridge of upper-layer packet bridge is at two go up a slope section right side, more high position bifurcateds of section of the straight bridge single file of bifurcated " fore-telling " font fork bridge in the same way, the bifurcated section outside of the left-hand bend bridge of directly adjacent with right side bifurcated in the same way " fore-telling " font fork bridge just is communicated with can finish the right-hand rotation function; The right-hand bend bridge of another group Grouping at Lower Level bridge is pitched section right side, bridge high position bifurcated at bifurcated " fore-tellings " font in the same way, an energy part and right side be the left-hand bend bridge levels structure of bifurcated " fore-telling " font fork bridge in the same way, remainder is in the inboard of this left-hand bend bridge, be connected with the straight bridge single file of bifurcated in the same way " fore-telling " the font fork bridge lower slope section in left side, make the not outside of the left-hand bend bridge of bifurcated " fore-telling " font fork bridge in the same way of right-hand bend bridge, reduce taking the crossroad area on the right side.
The design of the utility model new construction:
First, design for craspedodrome arch bridge and left-hand bend bridge: with independently four in the same way bifurcated " fore-tellings " font pitch bridge, divide prong composition facing each other two grouping bridges, four craspedodrome arch bridges of two grouping bridges respectively with the opposite in the same way the left-hand bend bridge of bifurcated " fore-telling " font fork bridge carry out multilevel traffic in by-path position, ground away from the crossroad, the shape of the curved bridge single file section in a left side is the arcuate structure that becomes 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 ground by-path away from the center, crossroad, prolonged left-hand bend bridge length, thereby reduced the left-hand bend bridge and will take very large-area problem at the parting of the ways because of the bridge length that the gradient needs, the crossroad is only needed more than 65 meters the distance between the building of angular direction, just can satisfy the needs of left-hand bend bridge, also just can satisfy the needs that the utility model combination freely-moving bridge takies ground and space.This just requires two of opposite face, and two craspedodrome arch bridges of bifurcated " fore-telling " font fork bridge rightabout driving are separate in the same way, need not same bridge, and vertical dislocation is arranged, promptly 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 rises jointly and between the bridge earth terminal spacing distance is arranged and not in same position, the straight bridge earth terminal of the lower bridge section of craspedodrome arch bridge is more near the center, crossroad, as long as straight bridge earth terminal is at zone, high position, the stage casing ground plane near opposite craspedodrome arch bridge, just abdicate the superjacent air space in left side for opposite craspedodrome arch bridge, promptly allow the left-hand bend bridge on opposite directly go out the curved bridge single file section in a left side, the multilevel traffic in addition the ground by-path at the parting of the ways of the left-hand bend bridge of realizing craspedodrome arch bridge and opposite at the side bifurcated that turns left.As long as there is bridge section under the part of two straight bridge single file sections in the grouping bridge to be positioned at the opposite in the same way among the branch prong of bifurcated " fore-telling " font fork bridge, Cheng Zhiqiao single file section partly descend the bridge section embed the opposite in the same way bifurcated " fore-tellings " font pitch bridge and divide structure among the prong, but straight bridge single file section is not passed the curved bridge single file section in a left side, opposite, makes the structure that does not have straight bridge single file section below the curved bridge single file section in a left side of this position and be one deck pontic.Center at the parting of the ways, two groups of straight bridge single file sections of two grouping bridges become multilevel traffic.On ground by-path away from the center, crossroad, ground of each curved bridge single file section in a left side prolongs track and all becomes multilevel traffic with bifurcated in the same way " fore-tellings " the font fork bridge of the ground by-path that turns left to be arrived, but the curved bridge single file section in a left side is not passed with bifurcated in the same way " fore-telling " font of the ground by-path that arrived of turning left and pitched bridge.
Second, design for the right-hand bend bridge: the right-hand bend bridge of telling on craspedodrome arch bridge right side, upper strata, can only be on the right side outside of the left-hand bend bridge of bifurcated " fore-telling " font fork bridge in the same way, could be communicated with in the bifurcated section outside of the left-hand bend bridge of bifurcated " fore-telling " font fork bridge in the same way with the right side, realize turning right with the mode of bridge.But the right-hand bend bridge of telling on lower floor craspedodrome arch bridge right side, can be on the right side inboard of the left-hand bend bridge of bifurcated " fore-telling " font fork bridge in the same way, with the left side in the same way the craspedodrome arch bridge lower bridge section of bifurcated " fore-telling " font fork bridge be communicated with, realize turning right, can take the area of crossroad so less with the mode of bridge.
Structure of the present utility model is:
The full unblocked cross composite bridge in the crossroad of two kinds of right-hand rotation bridges, comprise four Y-shaped arch bridges, it is characterized in that: each Y-shaped arch bridge all 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 a side and craspedodrome arch bridge 2 bifurcateds of turning left, this bifurcation is a bifurcation 15, make a craspedodrome arch bridge 2 and a left-hand bend bridge 3 form " fore-telling " font bifurcated bridge, then four Y-shaped arch bridges become four bifurcated " fore-telling " font fork bridges 1 in the same way;
Each in the same way the craspedodrome arch bridge 2 of bifurcated " fore-telling " font fork bridge 1 and left-hand bend bridge 3 have and play bridge earth terminal 4 jointly, and play bridge earth terminal 4 jointly to the section 14 side by side of two bridges between the bifurcation 15; At the fork of bifurcated " fore-telling " font in the same way zone, high position, bridge 1 stage casing, left-hand bend bridge 3 and craspedodrome arch bridge 2 bifurcateds; The zone, 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; From bifurcation 15 to straight bridge earth terminal 5 is straight bridge single file section 8; From bifurcation 15 to left-hand rotation bridge earth terminal 6 is the curved bridge single file section 13 in a left side;
Divide prong relative two in the same way bifurcated " fore-tellings " font fork bridge 1 form a grouping bridge, four in the same way bifurcated " fore-telling " font pitch bridge 1 and form two grouping bridges respectively; 8 one-tenth three-dimensional decussate textures of two groups of straight bridge single file sections of two grouping bridges; In same grouping bridge, straight bridge single file section 8 is positioned at the opposite in the same way among the branch prong of bifurcated " fore-tellings " font fork bridge 1, and this grouping bridge becomes one pair of embedded grouping bridge; The curved bridge single file section 13 in a left side be positioned at bifurcated in the same way " fore-tellings " the font fork bridge 1 at place and left side in the same way bifurcated " fore-telling " font pitch between the bridge 1;
Also comprise four right-hand bend bridges 16, each in the same way bifurcated " fore-telling " font fork bridge 1 a right-hand bend bridge 16 is all arranged, 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, in two grouping bridges, two straight bridge single file sections 8 are the upper-layer packet bridge stereo cross shape structure upper strata, and two other straight bridge single file section 8 is the Grouping at Lower Level bridge in stereo cross shape structure bottom; 9 preceding straight bridge single file sections 8 are the straight bridge single file section of upward slope 19 again from bifurcation 15 to stereo cross shape structure overlap section, are straight bridge single file lower slope section 20 from stereo cross shape structure overlap section 9 to straight bridge earth terminal 5;
The right-hand bend divergent ends 17 of the right-hand bend bridge 16 of upper-layer packet bridge is communicated with on the section right side, craspedodrome arch bridge 2 high position of bifurcated " fore-telling " font fork bridge 1 in the same way with this, and the arrival end 18 of turning right is communicated with in the outside of the left-hand bend bridge 3 of bifurcated " fore-telling " font fork bridge 1 on bifurcated " fore-telling " font fork bridge 1 right side in the same way in the same way with this;
The right-hand bend divergent ends 17 of the right-hand bend bridge 16 of Grouping at Lower Level bridge is communicated with on the section right side, craspedodrome arch bridge 2 high position of bifurcated " fore-telling " font fork bridge 1 in the same way with this, and the arrival end 18 of turning right is communicated with on straight bridge single file lower slope section 20 right sides of bifurcated " fore-telling " font fork bridge 1 in bifurcated " fore-telling " font fork bridge 1 left side in the same way in the same way with this.
The technique effect that design feature of the present utility model and preventing accordingly blocks up: with independent discrete four in the same way bifurcated " fore-tellings " font pitch two grouping bridges of 1 fen prong composition facing each other of bridge, straight bridge single file section 8 form of structure of two grouping bridges: the part section of the straight bridge single file of each of two grouping bridges section 8 is positioned at the opposite in the same way among the branch prong of bifurcated " fore-telling " font fork bridge 1, but do not pass or do not stride across the opposite curved bridge single file section 13 in a left side of bifurcated " fore-telling " font fork bridge 1 in the same way, this grouping bridge is two embedded grouping bridges.Like this from the through vehicles of 5 times bridges of straight bridge earth terminal of straight bridge single file section 8 on ground, with from the left side in the same way 6 times bridges of left-hand rotation bridge earth terminal of bifurcated " fore-telling " font fork bridge 1 left-hand bend bridge 3 to the left-hand bend vehicle merging track on ground, promptly the through vehicles and the left-hand bend vehicle of bifurcated " fore-telling " font fork bridge 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 on pontic one and merge the 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 bridge 1 is meant 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 in the left side, zone, high position, stage casing of craspedodrome arch bridge 2.At near the left-hand bend bridge 3 the bifurcation 15 and craspedodrome arch bridge 2 sections the clear height more than 4.5 meters of closing the symbol traffic specification is arranged preferably, make and to pass through motor vehicles below it.Left-hand bend bridge 3 turns left to use as motor vehicles." in the same way " be meant that the left-hand bend bridge 3 of each " fore-telling " font fork bridge is all identical with the bifurcated direction of craspedodrome arch bridge 2, promptly each left-hand bend bridge 3 is all at the left side of craspedodrome arch bridge 2 bifurcated, the directly left-hand rotation with other any pontic grade separation.So one in the same way the global shape of bifurcated " fore-telling " font fork bridge 1 be: to play a bridge earth terminal 4 be side by side to bifurcation 15 common for left-hand bend bridge 3 and craspedodrome arch bridge 2, this side by side section be two bridges side by side sections 14.Craspedodrome arch bridge 2 behind the bifurcated is straight bridge single file section 8, and the left-hand bend bridge 3 behind the bifurcated is the curved bridge single file section 13 in a left side.
The craspedodrome arch bridge 2 of same bifurcated in the same way " fore-telling " font fork bridge 1 and a common bridge earth terminal 4 of left-hand bend bridge 3 can be zonules, and 3 the bridge points of 2 bridge points of arch bridge and left-hand bend bridge of then keeping straight on are in same area; In this same area, 3 bridge points of 2 bridge points of craspedodrome arch bridge and left-hand bend bridge can be same positions, or certain longitudinal separation is arranged.
Craspedodrome arch bridge 2 is the current bridges 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 of bridge, and is meant the purposes of bridge.
Left-hand bend bridge 3 is the left-hand bend bridges that are used for crossroad right-hand traffic system, and " left-hand bend " is that purposes is the meaning of turning left.
The bifurcated section 7 of left-hand bend bridge 3 is the bridge sections that are used for passing from ground from the motor vehicles of the craspedodrome arch bridge 2 on opposite current usefulness, there are motor vehicles to pass the height of needs below the height of bifurcated section 7 need satisfy, are preferably in zone, the high position bifurcated that satisfies traffic specification with craspedodrome arch bridge 2 so the left-hand bend bridge 3 of bridge 1 pitched in same bifurcated in the same way " fore-telling " font.
Near left-hand rotation bridge earth terminal 6 preferably is positioned at before the bifurcation 15 of bifurcated in the same way " fore-telling " font fork bridge 1 of the ground by-path that left-hand bend will arrive ground, bifurcated in the same way " fore-tellings " the font fork bridge 1 of the ground by-path that left-hand bend will arrive is not passed, do not striden across to the curved bridge single file section 13 in a left side, pitches bridge 1 so that the left-hand bend motor vehicles pass bifurcated in the same way " fore-telling " font of the ground by-path that is arrived from ground.The left-hand bend motor vehicles on ground and right side in the same way 2 times through vehicles of bifurcated " fore-telling " font fork bridge 1 craspedodrome arch bridge to ground merge tracks, long ground, merging track section can be arranged, rather than have only one to merge the track point.Avoided the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge, make the through vehicles on left-hand bend vehicle and ground, the right side by-path merge the track, because of merging the too narrow traffic congestion problem that produces of bridge floor of track point in the pontic position of two bridges.
The stage casing of bifurcated " fore-telling " font fork bridge 1 is provided with the zone, high position in the same way, so that from the right side in the same way the left-hand bend vehicle of bifurcated " fore-telling " font fork bridge 1 below it, pass behind ground from left-hand rotation bridge earth terminal 6, thereby realize this bifurcated " fore-tellings " font fork bridge 1 and left-hand bend vehicle energy multilevel traffic in the same way from the right side.
Grouping bridge is by minute prong relative two combining structure of bifurcated " fore-telling " font fork bridge 1 in the same way, and the straightgoing vehicle that travels as the rightabout of two ground by-paths of crossroad opposite face realizes keeping straight on and left turning vehicle is realized the composite bridge of left-hand bend.A crossroad needs two grouping bridges, 8 one-tenth three-dimensional decussate textures of two groups of straight bridge single file sections of two grouping bridges.
Two groups of straight bridge single file sections 8 that " cross " meaning of 8 one-tenth three-dimensional decussate textures of two groups of straight bridge single file sections of two grouping bridges does not limit two grouping bridges 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 bridge single file section 8 has bending also still two groups of straight bridge single file sections 8 of two grouping bridges to be considered as decussate texture.The shape of stereo cross shape structure is meant overlooks observation above decussate texture, 8 one-tenth three-dimensional decussate textures of two groups of straight bridge single file sections of two grouping bridges, but the overlap section 9 of two groups of straight bridge single file sections 8 up and down of two grouping bridges is not connected, space length is up and down arranged, and it is current to satisfy motor vehicles.
Right-hand bend bridge 16 explanation to the upper-layer packet bridge: right-hand bend divergent ends 17 preferably is communicated with on go up a slope sections 19 right side of the straight bridge single file of bifurcated " fore-tellings " font fork bridge 1 in the same way with this, so as to satisfy the right side in the same way the vehicle pitched on the bridge 1 left-hand rotation bridge single file section 13 of bifurcated " fore-telling " font can thereunder move.Turn right arriving end 18 preferably bends bifurcated section 7 right sides and is communicated with in bifurcated " fore-telling " font left side of pitching bridge 1 in the same way in bifurcated " fore-tellings " font fork bridge 1 right side in the same way with this.That is to say that right-hand bend bridge 16 can become the levels structure on the curved bridge single file section 13 in a part left side of bifurcated " fore-telling " font fork bridge 1 in the same way on the right side, 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 single file section 13, and the outer ledge top of left-hand bend bridge single file section 13 is close in the inside edge of the bridge 16 of preferably turning right, so that the space that right-hand bend bridge 16 and left-hand bend bridge single file section 13 reduce above taking at the parting of the ways, when the turning radius of left-hand bend bridge single file section 13 was 15.0 meters, the outside minimum range of two right-hand bend bridges 16 of opposite face can have only 80.0 meters.
Right-hand bend bridge 16 explanations to the Grouping at Lower Level bridge: right-hand bend divergent ends 17 preferably is communicated with on the right side of the bifurcation 15 of bifurcated " fore-telling " font fork bridge 1 in the same way with this, so that satisfy the right side in the same way the vehicle on bifurcated " fore-telling " the font fork bridge 1 left-hand rotation bridge earth terminal 6 can thereunder move, the left-hand rotation bridge single file section 13 of lower position can be in lower floor like this, right-hand bend divergent ends 17 can be on the upper strata, form the levels structure, reduce the floor space of right-hand bend bridge 16 and left-hand bend bridge 3.Adding that the arrival end 18 of turning right is communicated with on straight bridge single file lower slope section 20 right sides of bifurcated " fore-telling " font fork bridge 1 in the same way with the left side, the occupation of land scope that plays right-hand bend bridge 16 does not exceed the occupation of land scope of left-hand bend bridge 3.When the turning radius of left-hand bend bridge 3 was 15.0 meters, the outside minimum range of two right-hand bend bridges 16 of opposite face and left-hand bend bridge 3 can have only 70.0 meters.Like this, the composite bridge of the technical program requires between the building at a diagonal angle, crossroad minimum range can have only 80.0 meters, and minimum range can have only 70.0 meters between the building at another diagonal angle.
The optimum position of right-hand bend divergent ends 17: the straight bridge single file section 8 from bifurcation 15 to stereo cross shape structure section is the straight bridge single file section of upward slope 19 again, and the right-hand bend divergent ends 17 of right-hand bend bridge 16 is communicated with on the section of upward slope 19 right sides with the straight bridge single file that bridge 1 pitched in bifurcated " fore-telling " font in the same way again.Like this, guarantee to reduce the length of right-hand bend bridge 16 under the condition that the right-hand bend bridge 16 bridge gradients need as far as possible, take length less near ground, crossroad by-path.
The optimum position of straight bridge earth terminal 5: for straight bridge earth terminal 5 optimum positions of the straight bridge single file of two embedded grouping bridges section 8 be positioned near the opposite in the same way bifurcated " fore-tellings " font pitch the bifurcated section 7 below ground locations of bridge 1.As long as make its through vehicles pass bifurcated section 7 from ground, then the height of bifurcated section 7 can reduce as far as possible, promptly the height of one deck bridge.
The preferred structure of left-hand bend bridge 3: the curved bridge single file section 13 in the left side of left-hand bend bridge 3 is preferably to the arcuate structure of 8 one-tenth three-dimensional decussate textures of two groups of straight bridge single file sections central area of two grouping bridges indent.Satisfy the gradient for the length that prolongs the curved bridge single file section 13 in a left side and meet the traffic specification requirement, and take ground, crossroad or locus as far as possible less, and the arcuate structure that the turn fractions of bridge 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 the 70.0-80.0 rice between place, diagonal angle, the crossroad building, and the small-sized crossroad of the above width in ten tracks is arranged between the building of two-way six-lane both sides, can both build combination freely-moving bridge of the present utility model.This just makes the utility model can be used for the crossroad, arterial highway in old city, realizes that old arterial street crossroad straightgoing vehicle and left-hand rotation car that people wish have no road occupying unimpeded.
The curved bridge single file section 13 min. turning radius design in a left side of arc concaves: the central point with 8 one-tenth three-dimensional decussate textures of two groups of straight bridge single file sections of two grouping bridges is the center, same grouping bridge is L to two curved bridge single file section 13 relative beeline length in an arc left side of stereo cross shape structure centre indent, the min. turning radius of two curved bridge single file sections 13 in an arc left side is R, in the scope of 30.0 meters≤L≤80.0 meter, the relationship of L and R is: R=L ÷ 4+8.When L=60.0 rice, R=23.0 rice.L is long more, illustrates that the crossroad area is big more, and then turning radius R can be big more, and the curved bridge single file section 13 in an arc left side can be born the fast more travel speed of motor vehicle.
" left side " " right side " on the left side described in the utility model or the right, the left side or the right side, right side, left side is meant that the people stands in common bridge earth terminal 4 positions of rising of some bifurcateds in the same way " fore-telling " font fork bridge 1, in the face of the stereo cross shape structure centre that two groups of straight bridge single file sections 8 of two grouping bridges are formed goes to judge " left side " or " right side ".
Two bridges described in the utility model section 14 side by side comprise two tracks at least.
Track described in the utility model or bridge are can pass through at least road or the bridge of a motor vehicle, but described track or bridge do not limit width, can increase width many cars side by side.
Craspedodrome arch bridge 2 described in the utility model is meant that the travel direction of motor vehicles on bridge is to keep straight on to stride across the bridge of crossroad for purpose, but the ascents and descents that the level height meaning is arranged, 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 is shaped as according to determining with ground level road.
Left-hand bend bridge 3 described in the utility model is meant and is used to turn left the bridge that motor vehicles use.The left-hand rotation bridge of right lateral system is at the left side, high position of craspedodrome arch bridge 2 bifurcated, and the direction that left-hand bend bridge 3 is directly turned is left turned, and does not need to do unnecessary detouring from ground, the right by-path and ground, opposite by-path.
Right lateral system described in the utility model refers to the traffic administration system that motor vehicles are kept to the right.
Intersection road occupying conflict described in the utility model refers to the traffic conflict between the motor vehicles at the parting of the ways.
Zone, high position described in the utility model is meant the pontic section of the following 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.
Advantage of the present utility model:
One, the vehicle that leaves the crossroad has the ground of broad as merging the track section: the through vehicles of bridge is kept straight on ground and is passed below bridge left-hand bend bridge pitched in bifurcated in the same way " fore-tellings " font on opposite under the straight bridge earth terminal of straight bridge single file section, with from the left side in the same way under the left-hand bend bridge of bifurcated " fore-telling " font fork bridge bridge to the left-hand bend vehicle merging track on ground, then can merge the track, avoid the disclosed screen frame shape of the Figure of description overpass bridge of Chinese patent 200820230509.5 to merge the too little too narrow and traffic congestion problem that causes of lane position at long ground section.
Two, be same as the former circuit of plane traffic substantially and do not have unnecessary detouring: it is unimpeded that two-way six-lane crossroad craspedodrome motorway and the motor-driven road of left turning vehicle are had no road occupying, and solved the traffic congestion that produces because of the two road usual friendship at the parting of the ways, problem blocks the traffic.This is a kind of unnecessary circuit that detours that do not have, motor vehicles only have ascents and descents to be different from the plane traffic at the parting of the ways, and driving route is same as the driving route on the existing surface road that traffic lights are arranged substantially, do not change direction of traffic and the custom of people in the usual friendship crossroad, do not get lost because of unnecessary detouring in can current process at the parting of the ways, the engineering quantity of building bridge in addition is less than existing any intercommunicated overpass, saves the bridge construction engineering cost.
Three, the little crossroad of two-way six-lane can be used: the utility model is only used four combinations of " fore-telling " font Y-shaped arch bridge in the same way, it is unimpeded fully just to have realized that the crossroad has no road occupying and conflicts, reduced the length of bridge 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 80.0 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.
Four, require between the building at a diagonal angle, crossroad minimum range can have only 80.0 meters, but minimum range can have only 65.0 meters between the building at another diagonal angle.For the less asymmetric crossroad of distance between the building that a diagonal angle is arranged, the utility model also can use, but has increased this scope of application greatly.
Five, composite bridge can be gone back in the pedestrian down: with four in the same way the composite bridge that is combined into of " fore-tellings " font Y-shaped arch bridge be used for the crossroad, the ground of crossroad can allow pedestrian and non motorized vehicle arbitrarily to pass through, and does not have the motor vehicle interference.
Inventive point of the present utility model is:
One, the pontic of craspedodrome bridge and left-hand bend bridge does not pass through mutually: this craspedodrome bridge does not pass, does not stride across the left-hand bend bridge on opposite, the left-hand bend bridge realization craspedodrome that just makes the vehicle on the craspedodrome bridge pass the opposite from ground; And the left-hand bend bridge does not pass, does not stride across left side the craspedodrome bridge and the left-hand bend bridge of bifurcated " fore-telling " font fork bridge in the same way, makes the vehicle on the left-hand bend bridge pass left side the craspedodrome bridge and the left-hand bend bridge of bifurcated " fore-telling " font fork bridge in the same way from ground.This structure makes through vehicles and the left turning vehicle on different bifurcated in the same way " fore-telling " the font fork bridges 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 on ground, be difficult for because of merging too little too narrow traffic congestion the in track, the disclosed screen frame shape of the Figure of description overpass bridge that has overcome Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass " merges the track and has only to merge the site, track and an easy problem that produces traffic congestion on overpass bridge.
Two, traffic conflict point is moved on to away from the by-path position of crossroad go multilevel traffic: the utility model is not the position that the road occupying conflict takes place to intersect at the plane traffic behavior, i.e. not interior position solution direct lane and the left turn lane intersection road occupying conflict of scope at the parting of the ways, but creationary this class traffic conflict point is moved on to away from multilevel traffic transport solution conflict on four ground by-paths of crossroad, thereby can take the ground and the space of crossroad minimumly.This unimpeded structure requires to reduce greatly to the annular region floor area of crossroad.As long as between the building of ground by-path eight lane widths are arranged, just can build up combination freely-moving bridge of the present utility model with the ground of crossroad diameter more than 65 meters, 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.
Three, on the by-path of the ground on two opposites, the ground of craspedodrome bridge prolongs the left-hand bend bridge of wearing the opposite under the track: keeping straight on relatively is two two-way craspedodrome arch bridges that rightabout is kept straight on, separate, not shared bridge; Be straight bridge earth terminal than the opposite in the same way bifurcated " fore-telling " font fork bridge common play the bridge earth terminal and more intersect the center near the stereo cross of two groups of craspedodrome arch bridges of two grouping bridges; Straight bridge earth terminal is near the opposite regional ground connection in high position of bifurcated " fore-tellings " font fork bridge in the same way, so straight bridge earth terminal has been reserved the space, high position of bifurcated " fore-telling " font fork bridge in the same way, opposite, allow the curved bridge single file section in a left side on opposite can be directly at the craspedodrome arch bridge bifurcated on left-hand bend one side and opposite, two bridge bifurcateds can directly turn left the left-hand bend vehicle and do not need unnecessary detouring, the vehicle that leaves straight bridge earth terminal can be passed from the turn left ground, bifurcated section below of bridge of opposite face, realize the multilevel traffic of through vehicles and opposite left-hand bend vehicle.
Four, the ground of left-hand bend bridge prolongs craspedodrome bridge and the left-hand bend bridge of wearing ground, left side by-path under the track: near the ground connection zone, high position of bifurcated in the same way " fore-telling " the font fork bridge on the left of the curved bridge single file section in a left side directly arrives by the left-hand bend direction, its ground prolongs the track and pitches the bridge multilevel traffic with bifurcated in the same way " fore-tellings " font in this zone, high position, and what just solved the straightgoing vehicle of the ground by-path that left-hand bend vehicle and left-hand bend will arrive and left turning vehicle intersects the road occupying collision problem.The left-hand bend vehicle does not detour, and has reduced unnecessary traffic conflict point.
Five, in the same grouping bridge, straight bridge single file section extend into the opposite in the same way in the branch prong of bifurcated " fore-tellings " font fork bridge: grouping bridges of bridges composition pitched in two relative bifurcated in the same way " fore-tellings " fonts of branch prong, and this grouping bridge is positioned on two ground by-paths of relative craspedodrome.Two in the same way bifurcated " fore-telling " font fork bridge is separate is not connected, but their straight bridge single file sections extend into the opposite in the same way in the branch prong of bifurcated " fore-telling " font fork bridge, two groups of straight bridge single file sections of two grouping bridges central area at the parting of the ways are the multilevel traffic of two-layer pontic, more humane traffic line also can be realized in pedestrian and non motorized vehicle in the road in ground, central area, crossroad.
Six, utilize the bigger condition of relative altitude difference between the straight bridge single file lower slope section of the bifurcation of lower floor's bridge and left side upper layer bridge, the initial part of right-hand bend bridge is placed on the top, latter end of the curved bridge single file section in bifurcated " fore-telling " font fork bridge left side in the same way, right side, the arrival end of right-hand bend bridge more is communicated with on the right side, high position with straight bridge single file lower slope section, make the latter end of right-hand bend bridge be placed on the inboard that bridge single file section is bent on this left side, avoided the outside of right-hand bend bridge curved bridge single file section on this left side, and reduced the area that the right-hand bend bridge takies the crossroad, make the littler crossroad also can use composite bridge of the present utility model.
Seven, two chimeric one-tenth composite bridges of disjunct unit bridges: the fork-shaped bridge of upper strata straight bridge single file section and the fork-shaped bridge that there is lower floor's straight bridge single file section on one on its right side are arranged by one, be connected into a unit bridges with two right-hand bend bridgings, cross composite bridge of two the chimeric one-tenth of disjunct unit bridges, have only some parts that structural deterioration or displacement are arranged, another unit bridges is all not influenced.And Chinese patent 200820230509.5 Figure of description disclosed be the overpass bridge that craspedodrome bridge, left-hand rotation bridge, the right-hand rotation bridge of four fork-shaped bridges is communicated with into screen frame shape fully, have only some parts that structural deterioration or displacement are arranged, whole screen frame shape overpass bridge is all influenced.
