Description

Two combination tunnels of turning right and keeping straight on " Y " font bifurcated tunnel
Technical field
The utility model belongs to the tunnel that makes the right-angled intersection automobile traffic unimpeded, particularly two independently the Y-shaped tunnel be combined into the craspedodrome motor vehicle that can make the crossroad opposite face (hereinafter to be referred as: straightgoing vehicle) and the right-hand bend motor vehicle (hereinafter to be referred as the have no road occupying unimpeded combination tunnel of the conflict right-hand bend car).
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 usual friendship crunode, 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 half the path resource.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 right-turn lane have no road occupying the conflict the overpass bridge minimum diameter below 120 meters, not only build the cost height, and the crossroad of the two-way six-lane in old urban area can not be built all; Make the crossroad traffic congestion of present old urban area very serious, the frequent traffic paralysis in the crossroad that has.
Chinese patent 200720043390.6 " the full unblocked overpass bridge of individual layer " discloses a kind of unimpeded combining structure associating bridge of establishing a direct puncture bridge and an annular bridge at the parting of the ways.Its shortcoming: the driver must see clearly operation sign at the parting of the ways, in case had little time lane change after not seeing clearly or seeing clearly, can cause promptly entering the place, crossroad in the lane change crosspoint and block up.This overpass bridge can not be used under the road of existing standard.
Chinese patent 200820230509.5 " directly right, left-hand rotation interchange overpass " discloses a kind of overpass bridge; Because the claims and the manual of this patent are very unclear to the description of technical scheme; But as if structure and the defective that just can understand this screen frame shape overpass bridge with Figure of description are: one, increased unwanted height and length: in the by-path position, ground away from the crossroad, continue one section pontic after the craspedodrome bridge passes again and just be connected with ground below the right-hand bend bridge on opposite, 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 right-hand bend bridge passes below the craspedodrome bridge of ground, right side by-path and right-hand bend bridge; Be connected with ground again after the lower bridge section of the craspedodrome bridge of ground, left 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; 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, even inwardly be recessed to minimum half to right-hand bend bridge and left-hand bend bridge through having only 15.0 meters, the minimum diameter of whole screen frame shape overpass bridge also causes wants 75.0 meters less.
Summary of the invention
The purpose of the utility model provides the road track that meets existing left lateral system traffic specification and arranges; Small size crossroad at two-way six-lane can be built, and two " Y " font bifurcated tunnels are combined into the have no road occupying combined type tunnel, two tunnels of conflict of the direct lane that props up on opposite face ground and right-turn lane.
The design that the utility model solves intersection road occupying conflict point is: at the parting of the ways, there is the road occupying of intersection conflict direct lane that prop up on opposite face ground and right-turn lane, and the right-hand bend car of opposite face ground by-path can not pass through when promptly straightgoing vehicle was current.But the not shared tunnel face that two craspedodrome tunnels will keeping straight on relatively are separate; Make a craspedodrome tunnel after passing the crossroad; Stride across through the right-hand bend tunnel of ground from " Y " font Y-shaped tunnel on opposite; The craspedodrome tunnel that just passes the crossroad goes out the tunnel earth point and more approaches the right-angled intersection center; And craspedodrome tunnel, opposite advance the tunnel point further from the center, crossroad, the distance of advancing the tunnel earth point and going out between the tunnel earth point in two craspedodrome tunnels of opposite face just drops to the right-hand bend length of tunnel that can multilevel traffic needs the degree of depth as right-hand bend tunnel, opposite.Just straight tunnel earth terminal is as long as rose to ground put the zone near the stage casing deep-seated in craspedodrome tunnel, opposite before; Just abdicate the lower position zone on right side for craspedodrome tunnel, opposite; Promptly let the right-hand bend tunnel on opposite directly go out right curved tunnel single file section, in addition the ground by-path multilevel traffic at the parting of the ways of the right-hand bend tunnel of realizing craspedodrome tunnel and opposite at the side bifurcated of turning right.Like this, the right-hand bend tunnel needs only the degree of depth in one deck tunnel, and all makes up the degree of depth that the tunnel the most all has only one deck tunnel, practices thrift the built tunnel expense, and is little to the civic landscape influence, and many tracks leaving the crossroad merge the difficult traffic congestion in track on ground.
The structure of the utility model is:
Two combination tunnels of turning right and keeping straight on " Y " font bifurcated tunnel; Comprise two Y-shaped tunnels; It is characterized in that: all there are a craspedodrome tunnel 2 and a right-hand bend tunnel 3 in each Y-shaped tunnel; Right-hand bend tunnel 3 is positioned at the right side in craspedodrome tunnel 2, and all at a side and craspedodrome tunnel 2 bifurcateds of turning right, this bifurcation is a bifurcation 15 in right-hand bend tunnel 3; Make a craspedodrome tunnel 2 and a right-hand bend tunnel 3 form " Y " font bifurcated tunnel, then two Y-shaped tunnels become two bifurcated " Y " font fork tunnels 1 in the same way;

It is that " car " or " vehicle " of bicycle is meant motor vehicle or refers to motor vehicles that the utility model does not indicate.
The advantage of the utility model:
One, can solve through vehicles and right-hand bend vehicle on two ground by-paths of the crossroad opposite face unimpeded problem that has no road occupying; Also solve through vehicles and right-hand bend vehicle on these two ground by-paths, with through vehicles in addition two ground by-paths of crossroad and the right-hand bend vehicle unimpeded problem that has no road occupying; It is too little to be specially adapted to the crossroad area, and the place that can not under four ground by-paths, all repair the tunnel solves nearly 70% traffic jam amount.Only surplus do not have craspedodrome and right-hand bend vehicle crisscross traffic such a case of two ground by-paths of opposite face in tunnel to need traffic lights to direct traffic.If on this has two ground by-paths of opposite face in tunnel, do not establish the right-hand bend grade separation respectively, the whole craspedodromes and the right-hand bend vehicle implementation of its crossroad have no road occupying unimpeded.
Two, two small-sized " Y " font tunnels; Reduce the disaster that geology changes: the disclosed screen frame shape of the Figure of description overpass bridge of Chinese patent 200820230509.5 " directly right, left-hand rotation interchange overpass " is the large-scale screen frame formula of an integral body overpass bridge that is connected as a single entity; Total length is very long, and floor space is very big, when in total length and floor space, there being geology to change; Cause whole large-scale overpass bridge not use, this crossroad access is paralysed fully.And the utility model to change into bifurcated in the same way " Y " the font fork tunnel that two independences are not connected to above-mentioned whole large-scale screen frame formula overpass bridge be minitunnel; Accomplish the right-hand rotation and the unimpeded grade separation function of keeping straight on of two ground by-paths of crossroad opposite face respectively with these two minitunnels; And can also with the right-hand rotation car and the unimpeded grade separation of straightgoing vehicle of two other ground by-path; Under identical driving speed per hour, identical technical data conditions such as the gradient; Compare the large-scale screen frame tunnel of Chinese patent 200820230509.5 Figure of description; Each minitunnel of the utility model shortens 30-35% than the total length of present large tunnel, and two minitunnels take up an area of the gross area and reduce 70-80%; In a word, the utility model than existing large tunnel, greatly reduces the risk of geological disaster with minitunnel.
Three, be same as the former circuit of plane traffic and do not have unnecessary detouring: can make the straightgoing vehicle and the right-hand bend car of two-way six-lane crossroad opposite face have no road occupying unimpeded; Right-hand bend car no unnecessary the detouring of directly turning right do not have the road occupying of intersection to conflict with the vehicle of another ground by-path of crossroad yet.The engineering quantity of building the tunnel in addition is less than, and practices thrift the built tunnel engineering cost.
Four, the little crossroad of two-way six-lane can be used: the utility model is only used two combinations in " Y " font Y-shaped tunnel in the same way; Reduced the length in tunnel in a large number than the existing full intercommunication tunnel that detours; Reduced floor space and space in a large number, made it have only 45 meters two-way six-lane small size crossroad, city can realize that also most of vehicle grade separation is unimpeded at round diameter.
Five, one deck tunnel is only used in the multilevel traffic of through vehicles and right-hand rotation vehicle: all make up the tunnel and all only use one deck tunnel.Littler to the civic landscape influence.
The inventive point of the utility model is:
One, the earth point front and back, tunnel that go out of entering tunnel earth point and another craspedodrome tunnel in craspedodrome tunnel misplace: the not shared tunnel face of keeping straight on relatively in the crossroad in two craspedodrome tunnels; But it is separate; A craspedodrome tunnel advance tunnel earth point and another craspedodrome tunnel go out the tunnel earth point have before and after dislocation, to drop to the needed climbing length of the straightgoing vehicle multilevel traffic degree of depth that can come with the opposite but the distance of dislocation is exactly the tunnel of turning right.The combination tunnel is formed in two relative bifurcated in the same way " Y " font fork tunnels of branch prong; Two in the same way bifurcated " Y " font fork the tunnel is separate is not connected, but their straight tunnel single file section part sections extend into the opposite in the same way in the branch prong in bifurcated " Y " font fork tunnel.
Two, the right-hand bend tunnel on craspedodrome tunnel and opposite is not crossed over each other: this craspedodrome tunnel does not stride across, does not pass the right-hand bend tunnel on opposite, and craspedodrome is realized in the right-hand bend tunnel that just makes the vehicle craspedodrome tunnel in stride across the opposite from ground.This structure makes through the multichannel vehicle behind the crossroad and realizes that on ground merging the track leaves the crossroad; 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 tunnel of Figure of description that has overcome Chinese patent 200820230509.5 " directly right, left-hand rotation intercommunication tunnel " merges the problem of the too narrow and easy very little generation traffic congestion of track point on bridge.
Three, move on to traffic conflict point away from the by-path position, ground of crossroad and go multilevel traffic: the utility model is not the position that the road occupying conflict takes place to intersect traffic behavior on the plane; I.e. not interior position solution direct lane and the right-turn lane intersection road occupying conflict of scope at the parting of the ways; But creationaryly move on to this type traffic conflict point away from the ground by-path of crossroad down with tunnel transport solution conflict, thereby ability take the ground and the space of crossroad minimumly.As long as the combination tunnel of the utility model just can be built up in the ground of crossroad diameter more than 45 meters, realize that old city has at least the crossroad access of a two-way six-lane to improve greatly, stop up the meaning that initiative is arranged for solving the little crossroad access in old urban area.
Four, the by-path on the ground on two opposites, the ground in craspedodrome tunnel prolongs the right-hand bend tunnel of striding the opposite on the track: keeping straight on relatively is two two-way craspedodrome tunnels that rightabout is kept straight on, separate, not shared tunnel; Be straight tunnel earth terminal than the opposite in the same way bifurcated " Y " font fork tunnel advance the tunnel earth terminal jointly more near the center, crossroad; Straight tunnel earth terminal is ground connection before the deep-seated in bifurcated " Y " font fork tunnel is put the zone in the same way near the opposite; So straight tunnel earth terminal reserved the opposite in the same way the deep-seated in bifurcated " Y " font fork tunnel put the rightward space position; Let curved tunnel, the right side single file section on opposite can be directly at the craspedodrome tunnel bifurcated on right-hand bend one side and opposite; Two tunnel bifurcateds can directly be turned right the right-hand bend vehicle and are not needed unnecessary detouring; The vehicle that leaves straight tunnel earth terminal can be striden across from the turn right ground, bifurcated section top in tunnel of opposite face, realize the multilevel traffic of through vehicles and opposite right-hand bend vehicle.
