Abstract
The interchange road crossing is characterized by that two carriageways of general fly-over are separated into two layers, i.e. upper and lower layers overpass another crossed trunk route so as to make the turning vehicle directly be guided onto said layer and the turning vehicle not conflict with straight-running vehicle, and the conflicting points between turning vehicles are also separated by said two layers, and said two layers also possess the function of overpassing two trunk routes. As compared with existent interchange structure, said invention features simple structure, occupied land not exceeding that for grade crossing, high speed, good passable property and low cost.
Description
The present invention relates to a kind of interchange road.
Interchange road generally all is to be made of cross-line D structure thing and ring road.Cross-line D structure thing is in order to eliminate the conflict point of intersection arterial highway craspedodrome wagon flow, and ring road solves the cross-cutting issue of turning vehicle.In various forms of interchanges, the turning ring road mostly is to draw from the right side, arterial highway, finishes the connection of road intersection up and down with the ground that the angle of turn of 90 °, 180 ° or 270 ° takies beyond the arterial highway.Draw on the right side of ring road and wide-angle is turned, and makes floor space very big, can not make full use of the space up and down of arterial highway, need a large amount of removal expenses, and the turning speed of a motor vehicle is limited, has the problem that interweaves.Some directional type graded crossing, ring road is drawn by arterial highway left side, takes up an area of but the craspedodrome arterial highway is outwards expanded increase, and keeping straight on curved section occurs, has reduced performance, and many, the complex structure of its level, cost are very high simultaneously.
Chinese patent manual C41123059A discloses a kind of crossroad bridge, it is made up of 4 that the are located at two arterial highway infalls one-way street modified line cross-line branch bridges that cross, the middle lane of every branch's bridge in the arterial highway draws on above the intersection of arterial highway, to intersection's modified line to left-lane, extend to the last access bridge initiating terminal of relative branch bridge then, modified line causes ground under to the middle lane again.Though this scheme has solved the big problem of floor space, the through vehicles of an one arterial highway and the left turning vehicle of two arterial highways need to travel through twice modified line, make the speed of a motor vehicle limited, current performance reduces, and very long access bridge is all arranged on four direction, and make cost higher, bigger to appearance of the city influence.
The objective of the invention is above-mentioned shortcoming at interchange road, a kind of new construction of cross-line D structure thing is proposed, make a cross-line D structure thing solve the problem of keeping straight on and intersecting and turning and intersect simultaneously, and it is interference-free to keep straight on, thereby be fully used in the space, simplify structure, reduced floor space, improved current performance.
For reaching this purpose, solution of the present invention is: the single file runway that parallel plane two craspedodrome runways on the arterial highway is separated into two aspects up and down of depth displacement, constitute the cross-line D structure thing of intersection, keep straight on like this and keep straight on, keep straight on and turn, turn and the conflict point of turning D structure thing elimination thus, this D structure thing is a direct lane, can be used as the part of turning ring road again, has multi-functional, and through vehicles is that straight line is crossed over, thereby make whole graded crossing road make full use of the space, simplify structure, improved current performance again, reduced floor space.
Wherein optimum implementation is: an arterial highway is separated under an overpass and one wears the tunnel, arterial highway crossing with it, from passing therebetween, from overpass with wear down the tunnel and draw two oriented branch bridges and oriented branch tunnel as left rotaring ring road to crossing arterial highway respectively, two branch's bridges and branch tunnel are respectively in the above and below graded crossing of the middle lane of crossing arterial highway.Because overpass and the following depth displacement of wearing between the tunnel are one times of clear height, and turning radius is increased, the turning speed of a motor vehicle improves.Branch's bridge and branch tunnel are drawn by the centre of arterial highway, make its floor space can not exceed the floor space of primary plane intersection.This programme can also be the structure of two-layer ground one deck and underground two-layer ground one deck on the ground, and promptly each aspect moves up or down one deck in the such scheme, becomes no subterranean layer or does not have the structure of aerial layer.
Utilize the variation of above-mentioned cross-line structure and directional type, winding type, loop ramp and two aspect track upper-lower positions and shape can constitute multiple combining form.
In above-mentioned all assembled schemes, the winding type graded crossing passage of the bicycle that the bicycle in the overpass can be walked to set up separates to improve current performance motor vehicle with bicycle.In the less area of bicycle, motor vehicle and bicycle can be mixed row.
Owing to adopted two runways to be separated into bilevel structure in the above-mentioned solution with same arterial highway, can finish the graded crossing of keeping straight on and turning compactly, and it is noiseless to keep straight on, make that its floor space is very little, simple in structure, current performance is good, speed of a motor vehicle height, cost is economized, and is little to appearance of the city influence.
Below in conjunction with drawings and Examples the present invention is described in further detail.
Figure is the graded crossing road sketch of most preferred embodiment of the present invention and bicycle passage.
←----, ←---be the motor-driven vehicle going route,
←---0 is the bicycle travel route.
As shown in the figure, overpass 1 and wear tunnel 2 down and cross over and pass through plane layer arterial highway CD respectively, cause intersection with branch's bridge 3 at overpass 1 interflow from the middle lane that intersects arterial highway CD is drawn flyover 4 to the initiating terminal modified line of interflow branch bridge 3 with branch's bridge 4 of overpass 1 shunting from intersection and cause middle lane to the back, middle lane top of intersecting arterial highway CD; Under the middle lane that intersects arterial highway CD, cause intersection with wearing the branch tunnel 7 that collaborates in tunnel 2 down, draw ground bridge 8 to the initiating terminal modified line of collaborating branch tunnel 7 to the back, middle lane below of intersecting arterial highway CD with the branch tunnel 8 of wearing tunnel 2 shuntings down from intersection and cause middle lane.Divide the bridge pier of flow branching bridge 4 to be located at the bridge both sides, but at its following traffick, but traffick on the flow branching tunnel 8 divided.DB direction left turning vehicle passes for 5 times from the modified line section of minute flow branching bridge 4 and enters it and lead the way 3; CA direction left turning vehicle is crossed over from the modified line section 9 in minute flow branching tunnel 8 and is entered its gug 7.Because the ramp 7,10 in 3, the 6 and two branch tunnels of leading the way of two branch's bridges all is arranged on the middle lane of CD arterial highway, thereby makes left rotaring ring road only take the road surface of a ring road width of CD arterial highway.Cross over intersection because the modified line section is one-lane mutual modified line, the modified line width is narrow, and can guarantee has the higher modified line speed of a motor vehicle under the short modified line segment length.Overpass is drawn branch's bridge 4 and is drawn the interflow 6 times at the overpass far-end, and overpass is introduced branch's bridge 3 and drawn in the shunting below the modified line section 5; Under wear the tunnel and draw branch tunnel 8 and on overpass far-end 10, draw the interflow, under wear the tunnel and introduce branch tunnel 7 and above modified line section 9, divide to flow down and draw, can make the interference at ring road shunting, interflow reduce to minimum like this, to improve the traffic capacity, the also interchangeable position of two branch's bridges and two branch tunnels, but poor-performing.Because overpass and the following depth displacement of wearing the tunnel are one times of clear height, so leading the way and 1/2 place of ramp length, its depth displacement equates with clear height, the joint and the branch tunnel of branch's bridge and overpass are located at herein with the following joint of wearing the tunnel, can obtain the maximum turning radius and the speed of a motor vehicle, not increase the length of cross-line structure again.Though overpass is three layers in the part, it has utilized ground floor, B1 and plane layer, and relatively ground level has only the height of a clear height, makes that it is led the way, the ramp is the shortest.When there are enough width the AB arterial highway, left turning vehicle is more, when requiring high speed noiseless again, can on the cross-line structure, set up the left turn lane, promptly the rear of wearing tunnel and interflow, branch tunnel at overpass and branch's bridge, down is provided with the spacer of a bicycle road width, or herein with overpass with wear down track of interruption, tunnel, if all be arranged to dedicated Lanes with changing trains or buses about all, just can eliminate intersection fully, cross, collaborate and shunt, make each to wagon flow safety, at a high speed, smooth and easy passing through.Simultaneously, the intervisibility window of driving sighting distance can be set in the tunnel, and when spacer not being set owing to eliminated the interflow, need branch tunnel, interflow and under wear the intervisibility window be set between the tunnel.Parallel section of two branch tunnels 7,8 should be communicated with, and utilizes gug 7 to ventilate in ground bridge 8 and leads to light.The modified line section is connected by two circular curves, and sweep is identical with the ring road sweep, and left turning vehicle is passed through so that constant vehicle speed is smooth and easy.At overpass with wear between the tunnel down and pass through, reverse end for end car and pass through in the modified line section by the CD direction to the tune car for AB.This programme the most important thing is that its current performance is good except that the little characteristics of floor space.Technical standard according to highway engineering provides the expressway below, the arterial street, three kinds of typical examples of urban centre road: clear height is got 5 meters respectively, 5 meters, 4,5 meters, the bridge crossing gradient gets 2% respectively, 5%, 7%, the ring road gradient gets 4% respectively, 5%, 7%, corresponding bridge crossing ramp, the length of leading the way is respectively 250 meters, 100 meters, 64 meters, half of this length is ring road greatest circle bilge radius and is respectively 125 meters, 50 meters, 32 meters, the limiting velocity of this radius correspondence is respectively 60 kilometers/hour, 40 kilometers/hour, 32 kilometers/hour, 70%～50% o'clock of ring road speed cut-off line speed, corresponding craspedodrome speed is respectively 86～120 kilometers/hour, 57～88 kilometers/hour, 43～60 kilometers/hour, the all realistic requirement of this speed, and substantially all greater than 37 kilometers/hour of speed of maximum traffic capacity correspondence and minimum oil consumption, minimum 40～60 kilometers/hour of the corresponding speed of polluting.Guaranteeing under preferably current performance, the high-speed condition like this, its floor space can be not more than the primary plane intersection, this is because left rotaring ring road is directed ring road, be again in the middle of the arterial highway, to draw, when the left-hand rotation design speed was not more than the right-hand rotation speed of a motor vehicle, it took up an area of the scope that can not exceed Yuanping City's cross-channel mouth right-turn lane, so its Breadth Maximum at the crossing is respectively 73 meters * 73 meters, 29 meters * 29 meters, 19 meters * 19 meters, only by the right-turn lane decision, as seen its area is very little.Getting the ring road width is 7 meters, when whole ring road curvature is consistent, the modified line segment length is respectively 83 meters, 50 meters, 40 meters, overpass CD direction length is respectively 666 meters, 500 meters, 336 meters, AB direction minimum length is respectively 271 meters, 221 meters, 149 meters, like this under the requirement that guarantees passage rate, one arterial highway direction length of overpass is very short, just the length of bridge is striden in simple-interchange, make it simple in structure, cost reduces, in addition its half at below ground, bridge in the middle of the arterial highway, makes it reduce ambient influnence again.Again because about its four direction, length is asymmetric, and its ring road can part be replaced by other forms, the cross-line structure also can have various variations, existing overpass bridge form all can with its combination, making has sufficient choice in planning, design, construction, can be fit to various actual conditionses and requirement.Its ring road is full directional type simultaneously, make that its path is short, circuit is clear and definite, travel direction is easy to identification, just the same with the level crossing rule of travelling, be entirely straight line and keep straight on, do not have the section of interweaving, can eliminate interflow, shunting when changing trains or buses about setting up again fully, thereby travel high speed, safety, convenience, these all are to realize under less cost and better simply structure.The ring road curved section need be widened, because of its on the ground or B1, do not take ground so do not understand more.Article two, the branch tunnel can be the cutting form, and no thoroughfare vehicle on it is to reduce cost.
This programme can also have following multiple combination:
When the AB arterial highway is enough wide, former one-way ramp can be become two-way ramp, the right-hand rotation car is drawn in the inboard, arterial highway, or with Yuanping City's surface layer right-hand rotation ring road become set up on stride or the ring road of underpass type, so that the bicycle of CD direction does not conflict with motor vehicle when plane layer passes through the crossing, AB direction bicycle can be from bridge crossing by not influencing autos only, when not ad hoc bicycle passage, also can realize that the intercommunication of bicycle travels like this in the cloverleaf mode, do not disturb simultaneously motor-driven vehicle going again, and ring road is made full use of, floor space further reduces.
When orographic condition allows to build one to three loop ramp, can change to three in the former directed ring road into loop ramp, it is over half that former grade separation link length is reduced, or do not build the branch tunnel, with further minimizing cost or adapt to other specific conditions.
When the left-hand bend vehicle do not require at a high speed or left turning vehicle more after a little while, can change former left rotaring ring road into the winding type ring road, or not intersect from both sides, CD arterial highway and directly to introduce to the cross-line structure, it is current to interweave on the cross-line structure, and structure is simplified.
When the AB direction is a subsidiary road or when not requiring high speed, can with former overpass and under wear the tunnel and become horizontal semicircle respectively, become the rotary interchange structure of separating up and down, former ring road by the circuitous overpass of introducing annular in both sides, CD arterial highway and under wear the tunnel, such two pairs of left turn traffics are respectively at overpass with wear down and interweave currently on the tunnel, and keep straight on and do not have the phenomenon that interweaves in the AB arterial highway, be on circuit speed reduce, but can make grade separation road CD direction length reduce 2/3, cost further reduces.
With separate the arterial highway that two runways intersect up and down, can cross over or pass through from the top of separating two runways from the below, like this can adaptation to the ground or the different requirements of original building.
Two arterial highways are separated into up and down two-layer and mutual graded crossing respectively constitute four-layer structure, be that an aspect is respectively walked in the four direction craspedodrome, turning is directly connected by directed ring road, and the current performance of this structure is best, the floor space minimum has better effect than four layers of present directed overpass bridge.
If present one-way road traffic system is changed into the traffic system of horizontal one-way road and vertical two ways, adopt the graded crossing of this programme, have only two left rotaring ring roads, and structure is fully used and is simplified, the four directions is that four directions, former one-way road is to intersecting 2/3 of required four simple-interchange bridge costs to required two grade separation structures of intersection, it is many that Vehicle By-pass is reduced, can satisfy practical needs, as long as the spacing of two one-way roads is short to rational degree, current convenience can be near the two ways traffic system.
The above is with regard to right lateral rule, and left lateral rule road structure can be identical, and just parallel ring road wagon flow direction is reverse, is to reduce the interflow conflict, can be with parallel ring road right and left mutually changing position on the structure.
In the form of above various combinations, bicycle in the overpass can be separated from motor vehicle, set up the winding type graded crossing passage of bicycle, this passage can be to stride bridge, tunnel, plane layer or its combination, round about manner can be built two, three or four circuitous channels at the arterial highway four direction, all the other are two or a craspedodrome passage, can realize that under the situation that does not increase graded crossing road level motor vehicle separates with bicycle in this way, and intercommunication is travelled respectively.On former road surface when narrower, because the separation of nonmotorized vehicle lane, utilized motorway space up and down, the motorway width is increased, remedy the shared road surface of left rotaring ring road, it is narrow to unidirectional one-lane road surface that it be can be applicable to, and the bicycle passage has played motor vehicle, bicycle and pedestrian's buffer action naturally, saved the expense and the occupation of land of artificial isolation strip, particularly important at such high speed crossing.The circuitous of C direction detours among the figure in order to remove from, can between branch tunnel and CD arterial highway, establish the bicycle tunnel of craspedodrome, and the motor vehicle grade separation only need increase some height up and down or the degree of depth gets final product, and utilizes the two-way ramp structure of motor vehicle so again, needn't be detoured to keeping straight in the bicycle four directions.
This programme can be applicable to 3-Leg Intersection and multiway intersection road equally.
