Description
Technical field
The invention belongs to the overpass bridge design of arterial highway right-angled intersection, particularly can just can realize keeping straight on and the complete unimpeded overpass bridge structure design of large radius turn (left-hand bend of right lateral system, the right-hand bend of left lateral system) with the individual layer grade separation.
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 vehicle on the two road can only a shared road on node, has lost the path resource of half, is certain to influence road speed and vehicular traffic.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 infinitely be widened, the unlikely runway that doubles.Even accomplished that the track is double, but nonmotorized vehicle lane, greenbelt and sidewalk will have been arranged, still to wait traffic lights, therefore the contradiction that still has people's car to mix row can not tackle the problem at its root.People have expected overpass bridge again, but in existing overpass bridge theory, it is very difficult accomplishing unimpeded fully, at first is to want mutilevel overpass, more will take very big land area and space, also will spend the very high cost of building.
For the traffic of right lateral system, present crossroad overpass bridge is the most scabrous be this road left-hand rotation car to cross over the right and opposite road vehicle intersect the road occupying problem, be to solve to intersect the road occupying problem, left changing lane will be used second layer grade separation, even the 3rd layer of grade separation.Whenever adding one deck grade separation will increase the height of overpass bridge greatly, rolls up the construction cost of bridge, rolls up the length of upper bridge section, rolls up the floor space of overpass bridge.
The applicant of this patent is at Chinese patent application 200920078443.7 " Straddle type right turning intersection for road junction ", only solve right-hand rotation and rotating problem with disclosed overpass bridge structure in two files of Chinese patent application 200920078459.8 " rotating overpass ", do not related to the problem of keeping straight on and turning left.And the most scabrous intersection road occupying problem of turning left just and keeping straight on of present overpass bridge in existing overpass bridge theory, for the problem of the mutual intersection road occupying that solves this left-hand rotation and craspedodrome, must be used second layer grade separation, even the 3rd layer of grade separation.Whenever add one deck grade separation and will increase height greatly, roll up the construction cost of bridge, roll up the length of upper bridge section, roll up the floor space of overpass bridge, thereby cause the most crossroads in the urban road network can't build overpass bridge at all, stay unnumbered usual friendship fast knot, cause blocking up of urban traffic, become the common fault in each flourishing city, the whole world.The purpose of this patent is exactly the solution that proposes at this world-famous puzzle, solves single-deck stereo cross bridge specially and realizes straightgoing vehicle and the car unblocked without hindrance problem of left-hand rotation.
Chinese patent 200720043390.6 " the complete smooth overpass of individual layer " discloses a kind of combining structure associating bridge of directly striding a bridge and an annular bridge of establishing at the parting of the ways.Its shortcoming: one is that a cross road has two kinds of driving standards, and the every cross road of crossing of driver will be seen clearly the operation sign of drawing on the ground, in case had little time lane change when not seeing clearly or seeing clearly, can cause carrying out lane change because of the crossing and cause traffic congestion or accident.The 2nd,----the road division standard of turning right is different from the road that has--craspedodrome---right-hand rotation now and divides standard in left-hand rotation from encircling interior craspedodrome outside ring, this makes the driver divide the standard driving by the road of existing left-hand rotation--craspedodrome---right-hand rotation easily before away from the cross mouth, had little time lane change when dividing standard, blocked up and accident and cause near just see craspedodrome behind the overpass bridge of this invention clearly the road of--left-hand rotation---turn right.In a word, this overpass bridge require--turning left,--road of turning right is divided the road that standard is different from existing turn left--craspedodromes---turn right and is divided standard, and this overpass bridge can not be used on the road of the road division standard of existing--craspedodrome---right-hand rotation of turning left to the outer craspedodrome of ring in encircle.
Summary of the invention
The purpose of this invention is to provide and meet existing right lateral system traffic rules: runway is from left to right divided standard for--craspedodrome---right-hand rotation road that turns left, and just can realize the complete smooth overpass of individual layer of keeping straight on, turning left to have no road occupying in the right-angled intersection single layer bridge; Also provide simultaneously and meet left lateral system traffic rules: runway is from left to right divided standard for--craspedodrome---right-hand rotation road that turns left, and just can realize the complete smooth overpass of individual layer of keeping straight on, turning right and having no road occupying in the right-angled intersection single layer bridge.In a word: the purpose of this invention is to provide and meet existing traffic rules, at the complete smooth overpass that right-angled intersection is kept straight on, large radius turn has no road occupying.
Design of the present invention is: design an annular bridge at the parting of the ways as main bridge, inner edge and outer rim in each ground by-path adjacent regions of annular bridge and crossroad, establish a single Ramp bridge that is connected with ground respectively, as long as the distance between the continuous contact of inside and outside two single Ramp bridges and annular bridge is at 0 ° at central angle--in the corresponding radian of 90 ° of angles, and two single Ramp bridges have two tracks, each ground by-path of crossroad is connected with single Ramp bridge of correspondence position respectively, just can realizes the right-angled intersection craspedodrome, it is unimpeded fully that large radius turn has no road occupying.
Inventive point of the present invention is: as long as the distance between the continuous contact of inside and outside two single Ramp bridges of each ground by-path correspondence and annular bridge is at 0 ° at central angle--in the corresponding radian of 90 ° of angles, just can change with the track that these two single Ramp bridges are realized entering annular bridge and left annular bridge.Just, when annular bridge has been designed to three annular tracks, when a single Ramp bridge of a certain ground by-path correspondence has two tracks to enter annular bridge, just there are two tracks of another corresponding single Ramp bridge to leave annular bridge, realize that two roads advance annular bridge and two conversions of saying annular bridge.
Structure of the present invention is:
The annular flyover of crossroad craspedodrome and large radius turn, comprise an annular bridge 1, it is characterized in that: be provided with four lane change positions 2 on annular bridge 1, it is circling point 4 in advancing that the ring inward flange 3 in each lane change position 2 has an end, and the petticoat 5 in each lane change position 2 has an end to be the circling point 6 of going out; In advancing circling point 4 and out the zone of the annular bridge 1 between the circling point 6 be lane change position 2, be the center of circle with the center of annular bridge 1, the circling point 4 and the position of circling point 6 out in the advancing of same lane change position 2, at 0 ° at central angle--in the radian of 90 ° of angle correspondences;
The interior circling point 4 that advances at a lane change position 2 is connected with the single Ramp bridge 7 of ring in, and the out circling point 6 at same lane change position 2 is connected with an outer shroud list Ramp bridge 8;

The single Ramp bridge 7 of whole interior ring that is connected with an annular bridge 1 is identical with the direction of rotation of whole outer shroud list Ramp bridges 8, being that the whole interior direction of rotation of encircling single Ramp bridge 7 and whole outer shroud list Ramp bridges 8 that same annular bridge 1 is connected all is a clockwise direction, perhaps all is counter-clockwise direction.
Four lane change positions 2 divide left and right row to be shaped on two kinds with the position relation of four ground by-paths that enter the crossroad:
The structure bridge of first kind of suitable vehicle right lateral system: lane change position 2 is being applicable to vehicle right lateral system near the by-path left side, ground, when the road traffic rules are right lateral system, each ground by-path the annular bridge 1 in left side on establish a lane change position 2, straightgoing vehicle and large radius turn car on the single Ramp bridge 7 of interior ring, counter-clockwise direction enters annular bridge 1 through circling point 4 in advancing, the direction of rotation of the single Ramp bridge 7 of ring and whole outer shroud list Ramp bridges 8 is all counter-clockwise direction all, when then the straightgoing vehicle counter-clockwise direction forwards the outer shroud list Ramp bridge 8 of ground, opposite by-path correspondence to, leave annular bridge 1 and realize keeping straight on; When large radius turn car (promptly turn left) counter-clockwise direction forwards the outer shroud list Ramp bridge 8 of ground by-path correspondence on the left side to, leave annular bridge 1 and realize large radius turn.Vehicle is arranged in the track that enters ground, crossroad by-path with identical in the arrangement of the track of the single Ramp bridge 7 of interior ring, all is that the left side is the left lateral track of large radius turn, and the right side is a direct lane, and is identical with existing right lateral system traffic rules.Be that track arrangement from left to right is left lateral the track---direct lane of large radius turn.
The structure bridge of this suitable vehicle right lateral system also can be used for train running in reverse direction to be used, realize the large radius turn (right-hand bend) and the craspedodrome of backward going, to enter annular bridge 1 from outer shroud list Ramp bridge 8, but its shortcoming is on the by-path of ground, vehicle will be by the right lateral track that from left to right is large radius turn--the arrangement mode of-direct lane enters the Liang Tiaodao on the outer shroud list Ramp bridge 8, but this track arrangement mode does not meet existing left lateral system traffic rules.So the structure bridge of this vehicle right lateral system is used for the right-hand rotation of left lateral system vehicle and when keeping straight on, can only says and can realize turning right and craspedodrome, but inconsistent with existing left lateral system traffic rules, and is difficult to the structure bridge of this right lateral system also is used for left lateral system traffic use.
The structure bridge of second kind of suitable vehicle left lateral system: lane change position 2 is being applicable to vehicle left lateral system near ground by-path the right, when the road traffic rules are left lateral system, each ground by-path the annular bridge 1 on right side on establish a lane change position 2, straightgoing vehicle and large radius turn car clockwise direction on the single Ramp bridge 7 of interior ring enter annular bridge 1 through circling point 4 in advancing, the direction of rotation of the single Ramp bridge 7 of ring and whole outer shroud list Ramp bridges 8 is all clockwise direction all, when then the straightgoing vehicle clockwise direction forwards the outer shroud list Ramp bridge 8 of ground, opposite by-path correspondence to, leave annular bridge 1 and realize keeping straight on; Large radius turn car (promptly turning right) leaves annular bridge 1 and realizes large radius turn when clockwise direction forwards the outer shroud list Ramp bridge 8 on the right to.Vehicle is arranged in the track that enters ground, crossroad by-path with identical in the arrangement of the track of the single Ramp bridge 7 of interior ring, all is that the right side is the right lateral track of large radius turn, and the left side is a direct lane, and is identical with existing left lateral system traffic rules.Promptly from left to right arranging is direct lane--the right lateral track of-large radius turn.
The structure bridge of this suitable vehicle left lateral system also can be used for train running in reverse direction to be used, realize the large radius turn (left-hand bend) and the craspedodrome of backward going, to enter annular bridge 1 from outer shroud list Ramp bridge 8, but its shortcoming is will be by from left to right being direct lane at the vehicle on the by-path of ground--the track arrangement mode in the left lateral track of-large radius turn enters the Liang Tiaodao on the outer shroud list Ramp bridge 8, but this track arrangement mode does not meet existing right lateral system traffic rules.So the structure bridge of this vehicle left lateral system is used for the left-hand rotation of right lateral system and when keeping straight on, can only says and can realize and craspedodrome, but inconsistent with existing right lateral system traffic rules, and is difficult to the structure bridge of this left lateral system also is used for right lateral system traffic use.
