Description
Technical field
The present invention discloses a kind of U-shaped revolution duct road of realizing the little grade separationization of urban built-up area level crossing, be cross or the T word level crossing finishing and be difficult to the grade separation reconstruction to have been built in existing city street road and street architecture improve, belong to road bridges and culverts means of transportation technical field.
Background technology
The metropolis of China generally has goes up century-old even history more remote, does not consider the huge wagon flow of today in most of periods of urban construction.Along with the continuous increase of city vehicle, road traffic is busy day by day, and the urban built-up area has been built to finish and is difficult to make adaptive change owing to street road and street architecture, and the traffic congestion phenomenon had become a great problem of city running already.Especially the urban structure road junction of fixing urban built-up area often becomes the focus of traffic congestion.The current method of river diversion that solves the intersection has: roundabout, traffic lights, viaduct, mistake tunnel, street and overpass bridge, these methods or realize because of excessive being difficult to that take up room, or bear because of huge being difficult to of construction fund, or may deceive because of effect and to be difficult to fundamentally deal with problems.Caused automobile engine idling is waited for and frequent starting has increased toxic emission owing to vehicle all waits in the intersection stop, not only wastes great amount of fuel oil and running time, has also aggravated urban air pollution.
With the akin technology of content of the present invention " U-shaped reversing bridge " be two patent (China Patent No. 201110338920.0 of the applicant; 201120425165.5): described " U-shaped reversing bridge " is that to be erected at detouring with vehicle revolution on the road surface be " the U-shaped reversing bridge " of purpose, it can better be implemented in respectively blocking up with alleviation to current continuously of intersection, urban built-up area, but because " U-shaped reversing bridge " is to be exposed to ground building, so still existence takies the large number of ground space problem of preciousness and the problem that bad weather influences traffic.
Task of the present invention is to have proposed more perfect improvement project on its basis.
Summary of the invention
The invention provides a kind of U-shaped revolution duct road of realizing the little grade separationization of urban built-up area level crossing, solve the traffic jam issue of intersection, urban built-up area.Do not having the space to arrange the intersection, urban built-up area of overpass bridge, utilizing U-shaped revolution to contain and realize little grade separation, all vehicles can each pass through to continuous, almost reach the current effect of overpass bridge.Make it big can't, overcome long shortcoming of existing construction cost height and construction period simultaneously in the urban built-up area because taking.
The U-shaped revolution duct road of the little grade separationization of realization provided by the invention urban built-up area level crossing, the technical solution of employing is as follows:
Comprise that a pair of U-shaped revolution that the arterial road of cross or T word level crossing and bilateral symmetry are provided with contains, two sides of U word mouth that U-shaped revolution is contained are for drawing culvert, both sides draw culvert respectively in arterial road and with the forward and reverse symmetry of arterial road, build with the arterial road parallel oblique; The U word bottom circular arc that U-shaped revolution is contained was that the street is contained, draw that culvert slowly has a down dip and with cross the street and contain and constitute one, constitute the U-shaped revolution of complete solid and contain.
When arterial road are broader, can leave the right lateral fare at the arterial road that draw outside containing.
The function that the U-shaped revolution of the present invention is contained is to make the urban built-up area level crossing that those can't grade separationization realize little grade separationization, so realize vehicle each to current continuously, cutout between namely replacing with continuous stream and improve vehicle flowrate and minimizing is blocked up.
Its passage mode of the present invention is:
1) forbid that all road vehicles sail the crossing into, the branch road right-hand bend vehicle directly right lateral fare outside U-shaped revolution is contained is directly turned right;
2) keep straight on and the left-hand bend vehicle need turn right that drawing of driving off that U-shaped revolution contains contained and contain along revolution and to travel, cross arterial road and draw through opposite side under arterial road and contain the arterial road road surface of climbing go back to of turning back, former desire through vehicles is turned right and is sailed branch road into and realize craspedodrome;
3) a former desire driving of turning left is contained the back and is kept straight on and sail arterial road into and realize rolling U-shaped revolution away from;
4) arterial road right-hand bend vehicle directly can directly be turned right along the right lateral fare that the U font is drawn outside containing;
5) through vehicles continues to travel along arterial road;
6) the left-hand bend vehicle sails U-shaped revolution culvert into after crossing the crossing, turns right after U-shaped revolution culvert is turned back and sails former left branch into and realize left-hand rotation.
So, all vehicles all under the no signal fluorescent tube system of crossing, realized each to travel continuously.
Urban traffic control office can the special period (night of low discharge, revolution contain in power failure and do not have illumination, heavy rain ponding etc.) restoring signal fluorescent tube system, all vehicles travel according to signal lamp control.
The present invention compares the good effect that has with existing viaduct, overpass bridge and correlation technique and is:
1, the good effect of comparing with viaduct, overpass bridge: at major trunk roads U-shaped revolution is set and contains, the branch road driving vehicle can be contained the at grade intersection of avoiding with the main road vehicle by U-shaped revolution, realize the current continuously of intersection, solved viaduct and can not solve the problem that vehicle turns left; U-shaped revolution is contained can realize little grade separationization at crossing, has also overcome the difficult problem of overpass bridge because taking up room and can't arranging in the urban built-up area greatly.U-shaped revolution culvert among the present invention is arranged in the arterial road, is not subjected to the restriction of road external space size, has positive effects such as the traffic capacity is big, simple in structure, cheap, the construction period is short simultaneously.
2, the good effect of comparing with " U-shaped reversing bridge ": " U-shaped reversing bridge " is the related facility (201110338920.0 that the applicant has applied for; 201120425165.5) design." U-shaped reversing bridge " is that to be erected at detouring with vehicle revolution on the road surface be " the U-shaped reversing bridge " of purpose, though it can better be implemented in respectively blocking up with alleviation to current continuously of intersection, urban built-up area, but comparatively speaking, the application's U-shaped revolution culvert still has tangible novelty and good effect:
(1) both shapes difference processed: design for solving the same problem with reversing bridge though the U-shaped revolution of the application is contained, both have diverse shape system, reversing bridge upwards climb along the road surface and at highest point across arterial road, be bridge in shape system; And U-shaped revolution contain be along the road surface downward-sloping and at lowest part across arterial road, be culvert in shape system.
(2) revolution is contained littler to ambient influnence: it all is to design for solving urban built-up area crossing traffic problem that revolution is contained with reversing bridge, urban built-up area street road and street architecture have been built and have been finished, street architecture mostly is mechanism's office and commercial Wang Pu greatly, frame bridge on the way can influence sight line and the commercial operation of mechanism and retail shop greatly, also can influence the city view, and just rare these adverse effects are contained in the revolution that is arranged on below the road surface, road surface.
(3) revolution is contained special adaptive domain: in the China north, arranged the ice period that reaches several months even this year every year, accumulated snow and freezing can increase vehicle climb difficulty and the danger when minor-circle turn of access bridge; Comparatively speaking, revolution is contained and to be arranged under the road surface, and northern ice and snow area can be contained part and add a cover the sleet canopy drawing, and can effectively avoid difficulty that ice and snow brings and dangerous.
(4) the lower construction of revolution culvert cost is faster: reversing bridge is supported by bridge pier, need to build at the scene, so the construction period is long and cost is higher; Revolution is contained and can be transported to on-the-spot assembling and finish in factory's piecemeal construction outside the venue, so the construction period is short and cost is lower.
3, the good effect of comparing with the described bridge of file (CN101403208A): know that by retrieval the disclosed bridge of file (CN101403208A) also can be realized the grade separationization of level crossing and passing through continuously of vehicle.But, the simple contrast as can be known, both are obviously different at aspects such as facility shape system, locus, technical object and technique effects.
The shape difference processed of (1) two kind of facility: the U-shaped revolution that the present invention is arranged in the arterial road is contained, and its shape is made as the culvert that places under the road; And file (CN101403208A) disclosed be a kind of place outside the road and the road on nearly circular arc bridge, its shape is made as bridge, both shapes difference processed is obvious.
The locus of (2) two kinds of facilities is different with applicable elements: the road inboard that is arranged on arterial road is contained in the U-shaped revolution of the present invention, and revolution culvert leader and rotating part below the road surface of arterial road, all do not take any space in addition, road surface respectively.And the disclosed bridge of file (CN101403208A) is dumbbell shape, and the major part of its circular arc pontic is all beyond the road surface.Different locus arranges applicable elements and the scope that has determined that they are different.Because be not subjected to the road outside whether to have the restriction that can utilize the space, the applicable elements that the U-shaped revolution of the present invention is contained is to have wideer pavement of road; And the applicable elements of the disclosed bridge of file (CN101403208A) is to have enough available spaces outside the road.
(3) two kinds of problem differences that the facility desire solves: the design scheme that why adopts bridge in the road is contained in the U-shaped revolution of the present invention, technical purpose is to realize little grade separationization of urban built-up area level crossing, the traffic capacity that improves existing road to be alleviating the urban built-up area traffic jam issue, i.e. U-shaped revolution is contained with little grade separation mode with the problem that solves liking the traffic jam issue of urban built-up area (also being master city, city usually).Because the street road of urban built-up area and along the street the road build to have built and finish, the street road is occupied by street architecture with the external space, difficulty have can be used for setting up file 1(CN101403208A) the road external space of described bridge, so the problem that this bridge can solve is to solve the city in the mode of transportation problem of building the zone by grade separation construction or reconstruction to urban road crossing with good conditionsi.Owing to need the road external space, file 1(CN101403208A) described bridge what can accomplish is the grade separationization at crossing but not little grade separationization, therefore not only be not suitable for the territory, urban built-up area, and in selecting for city development zone or the mode of transportation of building the zone, not having clear superiority again, these technical vulnerabilities perhaps are exactly the main cause that this bridge design is not adopted by scale.
Contrast is learnt, the present invention compares with the described bridge of file (CN101403208A), the urban built-up area traffic congestion difficult problem correlation technique that U-shaped revolution culvert can solve can't be accomplished, simultaneously, the present invention also simple and cheap in facility shape system, be not subjected to aspects such as steric requirements restriction to have good effect.
