Abstract
The present invention relates to a viaduct bridge for crossroads. It is characterized by that said viaduct bridge has no need of traffic light signal to make traffic control. Said viaduct bridge has two-way straight-going lane bridge floor, on the two-way straight-going lane bridge floor respectively are set at least two lanes, on the outer lanes of two sides of the bridge floor respectively are set forked branch lane for going down from bridge floor and forked branch lane for going up bridge.
Description
Technical field
The present invention relates to being connected to each other design and arranging of a kind of overpass, especially relate to a kind of viaduct that aglow green light is exempted from the road crossroad of being located at.
Background technology
Along with rapid economy development, various vehicles also increase sharply, and bring huge pressure to urban traffic, and traffic congestion, inefficiency, accident take place frequently becomes the hot issue of many urban traffics.How solving the problem that exists in the urban traffic has become one of focus of social concerns, and to build overpass bridge, viaduct in the crossroad of big and medium-sized cities very general for this reason.Wherein, overpass bridge floor space and engineering quantity are big, the cost height: though and existing viaduct floor space is more much smaller than overpass bridge with engineering quantity, cost is relative also lower, but can not the cancel all traffic-control device, especially can not solve the smooth and easy current difficult problem that vehicle turns left.Notice of authorization number provides a kind of global function viaduct for the utility model patent of CN2506685Y, divides two-layer bridge up and down, and every layer of bridge all has craspedodrome, right turn, left steering and tune back bend; The craspedodrome road is located at one ringwise on two camber lines in road, and it and bridge two ends road are along connecing; Right turn road and loop turn are tangent, and the left steering road then is located in the circle of loop turn, and circle is connected in the loop turn of its two ends and two-layer bridge up and down; Tune back bend is located between the two craspedodrome arc roads, and be the circular arc road and loop turn circumscribed.Notice of authorization number provides a kind of fork road global function spiral viaduct for the utility model patent of CN2611421Y, it divides upper and lower two-layer, every layer is equipped with a connection and pitches two-way one-way street rotating disk, between upper and lower two rotating disks, is provided with and can leads to the spiral ramp that connects two rotating disks; Bend that is connected in the bridge rotating disk of an end bifurcation design of bridge rotating disk is provided with one and returns bend between each fork road two-way street and last bridge rotating disk on the spiral road connects, and all is connected with a right turn road between two adjacent tine roads.
Summary of the invention
The objective of the invention is to the overpass bridge that is adopted at existing road crossroad, the shortcoming that viaduct exists, provide a kind of floor space and engineering quantity little, exempt from the viaduct of aglow green light.
The present invention is an individual layer list viaduct, if two-way direct lane bridge floor, be respectively equipped with at least 1 direct lane on the two-way direct lane bridge floor, can be preferably in according to the factors such as floor space of crossroad on the two-way direct lane bridge floor and establish 1～3 direct lane respectively, be positioned at both sides, place, crossroad at two-way direct lane bridge floor and be respectively equipped with bridge fork road down, the vehicle that is used on the bridge floor track, travelling come downwards to the bridge infralevoversion to, following bridge fork road is at least 1 track, be positioned at both sides, place, crossroad at two-way direct lane bridge floor and be respectively equipped with bridge fork road, needing under bridge to be used for the vehicle of left steering to go upward to the bridge floor track, last bridge fork road is at least 1 track.
During use, 1) current behind the bridge on the major trunk roads vehicle of keeping straight on by direct lane on the bridge; 2) vehicle of byroad craspedodrome is not gone up bridge, detours from road under bridge face track; 3) the right turn vehicle is not gone up bridge, and directly keeping right on the road surface turns to; 4) need bridge on the vehicle of left steering on the major trunk roads after bridge fork road Xia Qiao down detours in arc track, bridge lower edge left; 5) need the vehicle of left steering from pitching road on bridge around opposite side along last bridge through the arc track under the bridge on the byroad to bridge; 6) needing the vehicle of tune not go up bridge detours under bridge by counterclockwise.
The present invention is located on the crossroad, especially on the major trunk roads of crossroad, city.Compare with existing overpass bridge, outstanding effect of the present invention is (an only individual layer) simple in structure, floor space is few, cost is low, maintenance is easy, and is little to the influence of the city appearance of the city and environment; Compare with existing single viaduct, the most outstanding effect of the present invention is to exempt to establish traffic-control device, and all vehicles by the crossroad all can craspedodrome, right turn, left steering and even tune.This will play an important role to solving urban transport problems.
The present invention can be located on the major trunk roads of road crossroad, generally needs 6 tracks, if 8～10 tracks are arranged, better effect is arranged then.
Description of drawings
Fig. 1 is the structure and the user mode schematic diagram thereof of the embodiment of the invention.
Fig. 2 is the structural upright schematic diagram of the embodiment of the invention.
The specific embodiment
Following examples will the invention will be further described in conjunction with the accompanying drawings.
Referring to Fig. 1 and 2, the embodiment of the invention is an individual layer list viaduct, can be located on the major trunk roads of road, is provided with two-way direct lane bridge floor 1, and two-way direct lane bridge floor 1 is erected on the bridge pier 2.Be respectively equipped with at least 1 direct lane on the two-way direct lane bridge floor 1, can be preferably in according to the width of factors such as the floor space of road crossroad and major trunk roads and establish 2 direct lanes on the two-way direct lane bridge floor respectively, be positioned at both sides, place, crossroad at two-way direct lane bridge floor 1 and be respectively equipped with bridge fork road 3 down, the vehicle that is used on the bridge floor track, travelling come downwards to the bridge infralevoversion to, following bridge fork road 3 is at least 1 track; Be positioned at both sides, place, crossroad at two-way direct lane bridge floor 1 and be respectively equipped with bridge fork road 4, needing under bridge to be used for the vehicle of left steering to go upward to the bridge floor track, last bridge fork road 4 is at least 1 track.
During use, 1) current behind the bridge on the major trunk roads vehicle 11 or 12 of keeping straight on by direct lane on the bridge; 2) vehicle 21 or 22 of byroad craspedodrome is not gone up bridge, detours from road under bridge face track; 3) right turn vehicle 31～34 is not gone up bridge, and directly keeping right on the road surface turns to; 4) need bridge on the vehicle 41 or 42 of left steering on the major trunk roads after 3 times bridges in bridge fork road down detour in arc track, bridge lower edge left; 5) need the vehicle 51 or 52 of left steering from pitching road 4 on bridge around opposite side along last bridge through the arc track under the bridge on the byroad to bridge; 6) vehicle that need reverse end for end on the major trunk roads after detouring in arc track, bridge lower edge, is pitched bridge on the road 4 from the last bridge of opposite side earlier from the 3 times bridges in following bridge fork road left again; 7) need the vehicle of tune not go up bridge on the byroad, under bridge, detour by counterclockwise.
