Abstract

The present invention relates to the design of multiple passage viaduct and solves the technological problem of making the vehicles from all directions turn to the lanes in other directions easily without crossing with the lanes in other direction. The technological scheme is that inclined upstream and downstream ramps are set to link up the lanes in different directions. There are triangular zebra crossings marked in the cross between the lane and the ramp, lane passage mark and separating lines in the direction of the lane to the gallop bridge. There are also green land or parking lot in the area enclosed by the lanes and damps. The present invention has the advantages of simple structure, less engineering amount, and low cost.

Description

Cross-shape double-layered non-cross overpass

Technical field belongs to design, the erection technique field of multichannel region viaduct.

Just known to the applicant, at present, what taked domestic crossroad is three layers of overlapping formula overpass bridge to background technology, for example, north-south craspedodrome one deck, East and West direction another layer of keeping straight on, lower floor's (or in, lower floor) establishes one (two) rotating disk that goes in ring, and solves driving.Its drawback is: 1. east orientation is sent a car and will be turned left to the south orientation track, must produce two crosspoints and a point of contact.On the crosspoint or scramble for roads in advance, or give way wait.2. when reaching certain vehicle flowrate, several the cars that travel side by side around the whole belt rotating disk, the car of internal layer are played right lamp will go out ring, and outer field car is played left lamp and will be turned, and is promptly dangerous, and wagon flow is also slow.Establish the craspedodrome flow that the rotating disc type overpass bridge has only solved the East and West direction North and South direction for three layers, fundamentally do not solve the left-hand bend problem that four direction is sent a car.On the contrary, all left-hand bend vehicles are crowded on rotating disk.

Can cancel rotating disk at the parting of the ways, make each do not have intersect the raising vehicle flowrate that travels to sending a car? patent documentation discloses according to the retrieval, is exactly " lane double layer crossless stereo bridge on land " as the design of patent of invention notification number 1105084.The advantage of this design is to make sending a car of intersection four direction become one-way traffic not have the crosspoint.But it is too high that shortcoming is 1. costs: the total small-sized one-way street modified line of all the people present bridge crossing, and a double-deck bridge crossing, keep straight on and the F2/B2 bridge that turns left in another arterial highway.2. the gradient of its F2/B2 bridge must be high, and span is inevitable big, causes the high oil consumption of vehicle climbing.

In order to solve this difficult problem, those skilled in the art has also proposed other many technical schemes, as " X-shaped orientation type grade separation bridge " (application number: 92105467), " separated #-shape gallop bridge " (application number: 92109548), " crossroad bridge " (application number: 95114212) etc.The applicant thinks: the purpose that these technical schemes will reach is close, but technological means that is adopted and method are inequality.In addition, according to overpass bridge construction situation and the information that the applicant grasped, does not still have in the overpass bridge that has built up at present identical with the application's technical scheme, also less than in the openly identical with it design scheme of known information channel.

Summary of the invention technical problem to be solved by this invention is: the vehicle that all directions are travelled can both go to the track of left lateral freely from the right lateral track, and all do not have crosspoint (only having only a tangent near point) with each side vehicle always, reach take their own roads, be independent of each other, straightway purpose.

The technical solution adopted in the present invention is as follows: the ring road (1,2,3,4) that is provided with oblique bending between the two adjacent cross one another tracks (A, B, C, D) that are positioned on the plane inequality is linked up two adjacent tracks; Wherein (1,3) are down ramp, and (2,4) are up ring road.The right side of the direct of travel of (A, B, C, D) in the track indicates triangle zebra stripes (5) with the intersection of ring road (1,2,3,4).The direction that (A, B, C, D) leads to overpass bridge in the track indicates track token passing (6), center lines (7) and lines (8).Be positioned on the residing plane, track (A, B), the upright projection district (9) of the square shape that is surrounded by ring road (1,2,3,4) and track (A, B, C, D) constitutes green land or parking lot.This also is a technical scheme required for protection.

Description of drawings

Fig. 1, cross-shape double-layered non-cross overpass overlook the general structure schematic diagram.

Fig. 2, cross-shape double-layered non-cross overpass top layer plan structure schematic diagram.

Fig. 3, cross-shape double-layered non-cross overpass bottom plan structure schematic diagram.

Each label is defined as follows among the figure: A---and vertically by the direct lane in north orientation south, this figure stipulates to north, is east for south, Zuo Weixi, the right side down.B---direct lane from south to north.C---horizontal direct lane from west to east.D---direct lane from east to west.A, B track constitute bottom, and C, D track constitute top layer.1---the oblique bending ring road, link up D, A track, by D to the downward-sloping bending of A.2---the oblique bending ring road, link up A, C track, by A to the C bending that is inclined upwardly.3---the oblique bending ring road, link up C, B track, by C to the downward-sloping bending of B.4---the oblique bending ring road, link up B, D track, by B to the D bending that is inclined upwardly.5---there are 4 places in triangle zebra stripes area, is distributed in outside the crossing of A, D, B, C track and

ring road

1,4,3,2.6---the track token passing, demarcate and lead to the entrance of overpass bridge in A, B, C, D track, the sign that advances, turns right is arranged.7---the center lines, be yellow, be positioned at A, B, between C, the D track.8---lines are positioned on A, B, C, the D track.9---green land or parking lot, be on the residing plane of track A, B, be positioned at the region that upright projection constituted of the square shape that track A, B, C, D surround.It can constitute green land or parking lot, and the latter also has the function that reduces static vehicle flowrate (traffic congestion, road occupying) and improve dynamic vehicle flowrate.10---the left-hand rotation schematic lines, be shown in respectively on A-C, B-D, each track of D-A, C-B, expression is turned right earlier, turns left again.

Vehicle is as follows by the process of this overpass bridge: when turning left as the vehicle that come by A track direction such as need, pass the below in C, the horizontal track of D, turn right, up oblique bending ring road (2) changes the C track over to, has promptly finished the process of turning left.When and for example vehicle by C track direction such as need turn left, cross over the top in A, the vertical track of B, change the B track over to, promptly finished the process of turning left through descending oblique bending ring road (3).Vehicle turn-left process principle on B, the D track is also identical therewith.Be noted that; The vehicle that need turn left should travel to the track on the right according to arrow (ground " guiding arrow " and top " grade separation is kept straight on and the turning driving sign " board) the first lane change of indication.In addition, all right-hand bend vehicles travel at ground floor.

The applicant thinks: only need the guiding arrow is transferred to left road direction by right road, just applicable to the area of keeping to the left, as Hong Kong, Britain etc.

The specific embodiment: the applicant thinks the above technical scheme that provides and represented shape and the structure of each accompanying drawing, and with reference to the planning of the on-site landform of bridge construction, landforms and local administrative department, proposes concrete

Implementation method and preferred version.

In sum, the beneficial effect that the technical program has is: the first, can make the car from all directions All can forward the track that will turn to left lateral to by its right lateral track, improve the security reliability of vehicle operating And circulation. The second, simple in structure, quantities is little, and cost is low. The 3rd, floor space is little, has Good society, ecological benefits. Can supply a kind of selection scheme of urban construction, highway system Blind Points in Design of Grade Separation.
