Miniature applicable viaduct

Technical field

The present invention relates to a kind of urban traffic road structure, realize the side of two-layer omnidirectional multilevel traffic particularly to a kind of decussation road Method.

Background technology

Currently in order to solution urban traffic blocking, occur in that multiple three-dimensional transportation method, but generally speaking, otherwise be exactly that the number of plies is too many, Therefore pontic is the highest, and floor space is relatively big, though otherwise be exactly that the number of plies is few, but floor space is the least；Or it is exactly in same viaduct, has Track seems that comparison is crowded, and the comparison shown having is idle；Or form is single, it is impossible to meet the requirement of multiple special circumstances, and mutually closing In the transport structure of connection, it is impossible to thoroughly solve root problem.In modern Traffic Configuration, many places are unable to reach its construction and account for actual The requirement on ground.

Summary of the invention

It is an object of the invention to provide for existing Traffic Configuration the viaduct of the least flexible form of a kind of volume, make urban road complete Full crossings on different level comes true.Based on decussation structure or Y-shaped chi structure, by spill zig zag plane, general road plane and convex Zig zag plane is given in, and combines ambient conditions and realize the grade separation in track at the outer flexible arrangement spill zig zag plane of crossing center scope or convex zig zag plane.

The multi-level junction decomposition that the omni-directional stereo traffic of cruciform cross is needed is constructed to many places two-layer crossings on different level, and bed rearrangement stands Hand in bridge, without convex zig zag plane on convex zig zag plane, without spill zig zag plane under spill zig zag plane, thus reduce the height of whole viaduct.Right In the Through Lane that vehicle flowrate is bigger, the place wide in two tracks can be travelled without exception, so that the less right turn of some vehicles or left steering part car Being fully used in road, this is temporal multiplexing；In certain part of bed rearrangement viaduct, in overlying roaduay plane, the travel direction of vehicle is put down with lower floor road In face, the travel direction of vehicle is identical, perhaps has other parallel track in other words in the lower section of convex zig zag plane, perhaps has above spill zig zag plane Other parallel track, it is achieved multiplexing spatially.Or, during in spill zig zag plane or convex zig zag plane, inclined-plane travels, when driving to one Before fixed height or minuent are not reaching to the distance that can give in, what its travel direction was identical typically has two tracks can share a road surface section, combines Each travel direction lane flow amount little and to the utilization comparing vacant line and sailing track.In the place of conditions permit, by adjust camber and width with Fully make in the air across or have more width time underground is crossed, more relatively large vehicle also can be passed through safely and fast, reach the mesh of safe and feasible 's.Tune track both can be carried out in general road plane, it is also possible to track close with it for the zig zag plane required for tune track can be connected to one The part risen is connected.And due to the impact of physical features, particularly have overpass or have the place of subway, above-mentioned in " the full side of cruciform cross The multi-level junction needed to multilevel traffic decompose be constructed to many places two-layer crossings on different level " in, crossing center and crossing center extraneous to Article four, there is the connection of one section of general road plane between the two-layer crossings on different level in section, say, that the dispersion of certain part is built in from former crossing center Distant location.

In Fig. 10, (1), from right turn track westerly, north, from A the most upwards diagonal to B, is planar section, from C from B to C Diagonal enters general road plane gradually downward.

(2), from southern Through Lane, from A the most upwards diagonal to B, from B to D to E to F be overlying roaduay plane, from F Diagonal enters general road plane to G gradually downward.

(3), from north toward eastern left steering track, from H the most upwards diagonal to I, be overlying roaduay plane from I to J, from J gradually to Lower diagonal, to K, is lower floor's road plane from K to L, enters general road plane from L.

(4), from east toward northern right turn track, from general road plane the most upwards diagonal to M, it is overlying roaduay plane from M to N, from N diagonal gradually downward, to O, enters general road plane from O.

(5), from the Through Lane westerly of east, general road plane, to P, is lower floor's road plane from P to Q, is that general road is put down from Q to R Face, is lower floor's road plane from R to S, enters general road plane from S.

(6), from left steering track southward, east, from general road, plane enters into T, is lower floor's road plane, from U gradually downward from T to U Diagonal, to V, is lower floor's road plane from V to W, from W the most upwards diagonal to X, enters general road plane from X.

The general driving process in remaining track in like manner can push away.

Finally it should be added that, above during the general remark of Fig. 1 to Figure 10 schematic diagram, according to the requirement of particularity, its In three kinds of modes of giving in can be interchangeable because of the particular/special requirement of physical features.Can not build according to the size of vehicle flowrate and the impact of physical features, certain viaduct Some of which track, and realize arriving at by other viaduct.Between adjacent two viaducts, tune track as another viaduct Turn left or keep straight on needed for track.Usually, dotted line dash area is sufficiently large stop of facing on spill zig zag plane, and solid line dash area Stop is faced for sufficiently large on convex zig zag plane；If upper strata is convex zig zag plane, then its lower floor is general road plane；Put down if upper strata is general road Face, then its lower floor is spill zig zag plane, and vice versa.Described above based on right lateral regulation road, for specifying the city of road with left lateral, After then the image from the back side gained of drawing is new schematic diagram, and corresponding letter, numeral and word change front into, its implementation process just with The most identical.
