A kind of camber overpass bridge
The utility model is the improvement to existing overpass bridge structure, is concretely to disclose the camber overpass bridge a kind of, belongs to road and bridge means of transportation technical field.
Along with the continuous increase of city vehicle, road traffic is busy day by day, and a great problem that the traffic congestion phenomenon has become the city to run well especially at road junction, often becomes the focus of traffic congestion.The current method of river diversion that solves the intersection has: roundabout, traffic lights, viaduct, mistake tunnel, street and overpass bridge; These methods or realize because of excessive being difficult to that take up room; Or be difficult to bear, or may deceive because of effect and to be difficult to fundamentally deal with problems because of construction fund is huge.At present, urban traffic is not smooth, and the traffic congestion phenomenon is very general, waits the traffic lights time long, and the speed of a motor vehicle is slowly handled affairs the commuter time with delay, and traffic accident happens occasionally in the intersection.
Summary of the invention
The utility model provides a kind of camber overpass bridge, solved vehicle through the intersection smooth with wait traffic lights and vehicle and pedestrian to strive the road problem, reduced vehicle again and passed through the incident traffic accident in intersection.
The technical solution of the utility model is following: constitute two-layer flyover crossroad by arterial road and subsidiary road through upper and lower intersection, it is characterized in that: the middle part, road surface of major trunk roads, subsidiary road is the access bridge road surface for craspedodrome road surface, both sides; The upper strata that the arc bridge is located at flyover crossroad constitutes four layers of grade separation arc and word crossing and ring grade separation arc well word crossing stereochemical structure; The road surface of arc bridge is divided into left-hand rotation arc bridge circuit face and right-hand rotation arc bridge circuit face and revolution arc bridge circuit face; Import, the outlet of lonely shape bridge circuit face and turn right lonely shape bridge circuit face and revolution arc bridge circuit face of turning left is respectively equipped with arc pass bridge and arc lower pass bridge, and last arc pass bridge and arc lower pass bridge are communicated with the major trunk roads of lower floor and the access bridge road surface of subsidiary road.
The good effect of the utility model is: set up the arc bridge at the parting of the ways and constitute overpass bridge; Vehicle sails the intersection into; Keep straight on or left and right revolution current at the camber overpass bridge simultaneously to separately direction, do not need traffic lights, avoided between the vehicle of intersection and between the people through the time traffic accident that takes place; Promptly reduced traffic police's workload that directs traffic, realized that again sidewalk and vehicle ' road separate.

Among the figure 1, major trunk roads; 2, subsidiary road; 3, left-hand rotation arc bridge; 4, right-hand rotation arc bridge; 5, revolution arc bridge; 6, go up access bridge; 7, following access bridge; 8, access bridge road surface; 9, craspedodrome road surface; 10, flyover crossroad; 11, grade separation arc well word crossing; 12, tunnel road surface; 13, tunnel portal; 14, draw tunnel road surface down; 15, draw tunnel road surface on; 16, tunnel exit.
The specific embodiment:
As shown in Figure 1, in the utility model, constitute upper and lower two-layer flyover crossroad 10 by arterial road 1 and subsidiary road 2 intersections, the middle part of major trunk roads 1, subsidiary road 2 is craspedodrome road surface 9, both sides are access bridge road surface 8; The upper strata that the arc bridge is located at flyover crossroad 10 constitutes four layers of grade separation arc well word crossing 11 and ring grade separation arc well word crossing 11 stereochemical structures; The road surface of arc bridge is divided into left-hand rotation arc bridge circuit face 3 and right-hand rotation arc bridge circuit face 4 and revolution arc bridge circuit face 5; Left-hand rotation arc bridge circuit face 3 is respectively equipped with arc pass bridge 6 and arc lower pass bridge 7 with import, the outlet of right-hand rotation arc bridge circuit face 4 and revolution arc bridge circuit face 5, and last arc pass bridge 6 is communicated with the major trunk roads 1 of lower floor and the access bridge road surface 8 of subsidiary road 2 with arc lower pass bridge 7.
When vehicle sailed flyover crossroad 10 into, through vehicles can be directly current through two-layer flyover crossroad 10; Left-hand bend and right-hand bend and the curved vehicle of revolution sail left-hand rotation arc bridge 3 respectively into through last arc pass bridge 6; Right-hand rotation arc bridge 4; Revolution arc bridge 5; Forward the major trunk roads 1 or subsidiary road 2 crossings of respective direction to through the arc bridge, enter into the access bridge road surface 8 of major trunk roads 1 or subsidiary road 2, accomplish turning driving through arc lower pass bridge 7.
Fig. 2 is another embodiment of the utility model, establishes two left-hand bend arc bridges 3 on flyover crossroad 10 upper stratas and constitutes the three-layer stereo structure; There are two left-hand rotation tunnel road surfaces 12 to be located at the underground of flyover crossroad 10 road surfaces; Vehicle draws tunnel road surface 14 through being provided with above the access bridge road surface 8 under tunnel portal 13 entering; Process of passing through tunnel road surface 12 moves ahead, through on draw tunnel road surface 15 and arrive tunnel exits 16 and realize the turning driving purposes.
