Description

The combining structure of four " L " shape arch bridges that turn round in the same way
Technical field
The present invention is the combining structure that is used for the combination of four " L " shape arch bridges of right-angled intersection, and particularly four are turned round in the same way " L " unimpeded structure has no road occupying for the be combined into straightgoing vehicle that can make the crossroad and the large radius turn car (the left-hand rotation car of right lateral system, the right-hand rotation car of left lateral system) of shape arch bridge.
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.
Chinese patent 200720043390.6 " the full unblocked overpass bridge 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, and oneself can not lane change in case do not see or see clearly the back clearly, can cause that origin cause of formation lane change causes go into the crossing before block up.The 2nd,----the road division standard of turning right is different from the road of existing left-hand rotation--craspedodrome---right-hand rotation and divides standard in left-hand rotation in craspedodrome from inside to outside, this make the driver very easy before away from the cross mouth road with existing turn left--craspedodromes---turn right divide the standard driving, see craspedodrome behind the overpass bridge near this invention clearly--left-hands rotation---oneself has little time lane change during the road division standard of right-hand rotation.In a word,----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 this overpass bridge can not be used on the road of the road division standard that has--craspedodrome---right-hand rotation now in left-hand rotation in the craspedodrome from inside to outside of this overpass bridge requirement.
Summary of the invention
The purpose of this invention is to provide and meet the existing driving system of keeping to the right, or arrange in the track of left lateral system traffic specification, promptly runway is from left to right divided standard for--craspedodrome---right-hand rotation road that turns left, only with four " L " shape arch bridges combinations of turning round in the same way, just can realize craspedodrome, the large radius turn unimpeded combining structure that has no road occupying at right-angled intersection.In a word: the purpose of this invention is to provide the combined type smooth overpass that right-angled intersection large radius turn car and straightgoing vehicle are had no road occupying.Also provide the floor space of trying one's best few bridge construction, trying one's best few and realize the crossroad combined type smooth overpass that has no road occupying.
Design of the present invention is: direct lane is the shape road directly, but direct lane detours on ground again after detouring with the large radius turn track.The runaround that strides across ground of four " L " shape arch bridge solids of turning round has in the same way solved on the runaround on " L " shape arch bridge and ground vehicle and has intersected the road occupying collision problem.And in direct lane and the large radius turn track, the detour track that will leave the crossroad of FEFO comes the runaround arc outside on ground, does not intersect road occupying when leaving.
Structure of the present invention is:
The combining structure of four " L " shape arch bridges that turn round in the same way, comprise four " L " shape arch bridges 1 that turn round in the same way, each " L " shape arch bridge 1 that turns round in the same way all have on the by-path of ground upper bridge section 2 and at the parting of the ways the circle in lower bridge section 3, it is characterized in that: empty " ten " font structure in four " L " shape arch bridges 1 that turn round are in the same way formed, four upper bridge sections 2 are at the decentre far-end of interior sky " ten " font structure, and four lower bridge sections 3 are in the central area of interior sky " ten " font structure; Arrive lower position as direction of rotation with lower bridge section 3 high positions, the lower bridge section 3 of four " L " shape arch bridges 1 that turn round in the same way all is counter-clockwise direction or all is that clockwise direction turns round.
