Abstract
The present invention is one city overpass with four intercommunicated ways. The new design of the present invention includes leading the left turning lane via flyover to most left in the same layer as the right turning lane before jointing the exit; leaving one area without vehicle to build crossed ground pavement and overbridge; and a two-layer structure for the stereo crossing of pavement and vehicle lanes. The present invention has simplified lane crossing in the central area, fast running of straight forward vehicle and great passing capacity.
Description
(1) technical field
The present invention relates to highway and urban road four-legs intersection interchange viaduct.
(2) background technology
The rapid increase of vehicle has caused great pressure for the traffic of highway, the intertwined point of road network particularly, obstructing problem to vehicle is outstanding especially, the grade separationization of intersection is subject to people's attention day by day, the technical scheme of the present overpass bridge of using always, " road intersection planning and designing and construction " related cloverleaf formula as the publication of Heilungkiang science tech publishing house, annular, various ways such as rhombus, mostly there is floor space big, engineering quantity is big, investment is big, long construction period, the number of plies are difficult to take into account the pedestrian after a little while and bicycle passes through problems such as crossing from ground, makes it be difficult to implement or can't implement at all at a lot of highways and city road crossing.
(3) summary of the invention
The purpose of this invention is to provide a kind of two laminar overpass bridges,, realize car, pedestrian shunting with the floor space of track at grade intersection, mutually noninterfere, the without hindrance formula of intercommunication is current fully separately.The present invention does not have loop ramp, and few the occupation of land, the number of plies is few, and is simple in structure, and engineering quantity is little, and cost is low, short construction period; Owing to do not have loop ramp, driver to be convenient to identification, reduce the Vehicle By-pass expense; The ground of realizing pedestrian and bicycle is current, has improved the comprehensive function of use of two laminar overpass bridges.The present invention tries hard to the simplest structure, minimum occupation of land, and minimum cost realizes above function.
(4) description of drawings
The geometry of invention is provided by following embodiment and drawing.
Figure (1) is the floor map of the two-layer intercommunicated overpass with separated traffic lanes and pavements of proposition according to the present invention.The object of the present invention is achieved like this.The track of being turned left in each road causes the outer course in left side with bridge crossing in the entrance, promptly with reverse right-turn lane people having a common goal layer together, two in opposite directions the track in the zone of intersection, center, insert left turn ramp and right turn ramp respectively again, enter the outlet section track of another homonymy, therefore simplified the intersection of track in the zone of intersection, center, make the craspedodrome main line road of diaxon in the zone of intersection, center, realize the graded crossing of no conflict point, satisfy straight fast running of craspedodrome motor vehicle and the bigger requirement of the traffic capacity; With the bridge crossing original position of the left turn lane on each road to intersecting one section road that does not have traffick that the edge, center reserves, respectively as sidewalk and construction pedestrian overcrossing, form ground " ten " font People's Bank of China stereo channel, thereby realize that car, pedestrian take their own roads the without hindrance formula graded crossing of the complete intercommunication of mutually noninterfere.
(5) specific implementation method
Below in conjunction with scheming (1) four-legs intersection with two-way six-lane is details and the function situation that example describes the scenario-frame that proposes according to the present invention in detail.
The road of this overpass bridge laterally is an axle (X), vertically is axle (Y).The current track that left-hand bend, craspedodrome, three kinds of functions of right-hand bend are respectively arranged of the positive and negative direction of diaxon motor vehicle, their path:
Axle (X) positive direction:
Turning left: road (1) inlet,---------access bridge---ground left turn ramp---road (7 ') exports bridge crossing (13) access bridge.
Keep straight on: road (2) inlet---road (2 ') outlet.
Turn right:---ground right turn ramp---road (the 12 ') outlet of road (3) inlet.
Axle (X) negative direction:
Turning left: road (6) inlet-access bridge,------access bridge---ground left turn ramp---road (12 ') exports bridge crossing (14).
Keep straight on: road (5) inlet---road (5 ') outlet.
Turn right: road (4) inlet---ground right turn ramp---road (7 ') outlet (this road and coaxial positive direction left-turning pathways outlet interflow are looked the wagon flow situation and also can each be inserted together, below have merging lane all can be) with reference to processing.
Axle (Y) positive direction:
Turn left;---access bridge---bridge crossing (15)---overhead left turn ramp---access bridge---road (the 6 ') outlet of road (7) inlet.
Keep straight on:------bridge crossing (17)---access bridge---roads (8 ') export access bridge road (8) inlet.
Turn right:---access bridge-overhead right turn ramp---access bridge---road (2 ') exports road (9) inlet.
Axle (Y) negative direction:
Turn left:------overhead left turn ramp---access bridge---road (1 ') exports access bridge-bridge crossing (16) road (12) inlet.
Keep straight on:------bridge crossing (18)---access bridge---roads (11 ') export access bridge road (11) inlet.
Turn right; Road (10) inlet---access bridge-overhead right turn ramp---access bridge---road (6 ') outlet.
The crossing is passed through on the ground of pedestrian and bicycle.Because the track of its left-hand bend of diaxon four-way (1), (6), (7), the changed course of (12) entrance in the road respectively, so to intersecting the center road of one section current motor vehicle is arranged respectively from the above-mentioned overpass locations of bidding farewell, utilize the access of this section road as walkway, (O) locates collecting and distributing at the intersection center, can arrive any purpose block, concrete way is; Locate to establish respectively pedestrian overpass (19), (20) leap road (2), (3) and road (4), (5) at the position of axle (X) (A), (B), between the position in axle (Y) road (7) (C), (D), establish a pedestrian overpass (21), it crosses over the left-hand bend ground ring road of (6) left-hand bend ground ring road, linear road (2), (5) and road (4) respectively in the intersection center, position (C), (D) locate end points all ladder access bridge crossing (21) up and down, and locates to establish ladder access bridge crossing (21) up and down at intersection center (O) again.The pedestrian overpass (19) of (A) crosses over from the position as the pedestrian of the 3rd block, to intersecting ground, center, keeps straight on and passes through intersection center (O), locates pedestrian overpass (20) by position (B) and crosses over, to first block.If locate the pedestrian overpass at intersection center (O), then can be from the position People's Bank of China's ladder access of (C), (D) down to the second, the 4th block.In like manner the pedestrian of first block can be from the position (B) bridge crossing (20) toward each purpose block; The pedestrian of second block from ground in the position access bridge of (D) underpasses (10), (11), by pedestrian overpass on the ladder access (21), the ladder access underpasses (8) of keep straight on from the position (C), the access bridge of (9) can be to the 4th block.If down to ground, can arrive the 3rd, first block by pedestrian overpass (19), (20) that position (A), (B) locate from intersection center (O) ladder access.The pedestrian of the 4th block pedestrian overpass (21) from the ladder access of position (C) in like manner, (O) locates transfer at the intersection center, toward each purpose block.
The diaxon direct lane can be outwardly-bent in the intersection central area, to obtain more free from worry space, walkway; Parallel as People's Bank of China's ladder access being made flat slope and ladder road, bicycle and pedestrian simultaneously then can pass through; The present invention can be provided with diaxon and increase the track according to on-site actual situations such as wagon flow, landform.
