Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only illustrative and should not be construed as imposing any limitation on the scope of the present invention.
It should be noted in advance that, due to the symmetry of the overpass structure, the lifting point and the landing point in the present application both refer to the lifting point and the landing point in one passing direction, and when viewed from the opposite passing direction, the lifting point becomes the landing point, and the landing point becomes the lifting point.
As shown in fig. 1, the existing overpass structure includes, from outside to inside, a ground sidewalk a, a ground sidewalk d, a ground sidewalk e, a overpass sidewalk b, an overpass lane c, and an overpass lane f. The overpass sidewalk b, the overpass non-motor vehicle lane c and the overpass motor vehicle lane f form an overpass ground road (or other crossing objects) 15, and the ground auxiliary road sidewalk a, the ground auxiliary road non-motor vehicle lane d and the ground auxiliary road motor vehicle lane e are level-crossed with the ground road. Referring to fig. 2, i in fig. 2 represents the flow direction of the ground auxiliary road motor vehicle, and ii represents the flow direction of the overpass non-motor vehicle. At a lifting point 11 and a landing point 12 of the existing overpass, a conflict point exists between the flow direction of a motor vehicle on a ground auxiliary road and the flow direction of a non-motor vehicle on the overpass, so that traffic accidents of colliding people or non-motor vehicles easily occur, and the traffic organization is complex.
As shown in fig. 3, the present application provides a flyover for eliminating a traffic conflict at a landing point, and a flyover pedestrian non-lifting point 21, a flyover motorway lifting point 22, a flyover motorway landing point 28, and a flyover pedestrian non-lifting point 29 are sequentially arranged along a traveling direction of the flyover. The ground road is arranged in front of the overpass bridge non-lifting point 21 and comprises a sidewalk, a non-motor vehicle lane and a motor vehicle lane which are sequentially arranged from outside to inside.
At the overpass people non-lifting point 21, the sidewalk is branched into a ground side road sidewalk a and an overpass sidewalk b, and the non-motor lane is branched into a ground side road non-motor lane d and an overpass non-motor lane c. The overpass sidewalk b and the overpass non-motor vehicle lane c are combined into a human non-overpass bridge and start to be lifted up for climbing.
Behind the overpass human non-lifting point 21, the motorways diverge into an overpass motorway f and a ground-assisted motorway e, which is located between the overpass motorway and the human non-overpass.
At the overpass motorway lifting point 22, the overpass motorway f starts climbing, and the ground auxiliary motorway e remains at ground level.
Above the crossing object 25, the human non-flyover merges with the flyover vehicle lane f to cross the crossing object 25.
At the overpass vehicle lane landing point 28, the overpass vehicle lane f lands.
After the overpass vehicle lane landing spot 28, the overpass vehicle lane f and the ground auxiliary vehicle lane e merge into a vehicle lane.
At the overpass people non-landing point 29, people non-overpass bridge lands, people non-overpass bridge branches into an overpass sidewalk b and an overpass non-motorized lane c, the overpass sidewalk b and a ground auxiliary road sidewalk a are combined into a pedestrian road, and the overpass non-motorized lane c and a ground auxiliary road non-motorized lane d are combined into a non-motorized lane.
Referring to fig. 4, in fig. 4, i represents a flow direction of a motor vehicle on the ground and ii represents a flow direction of a non-motor vehicle on the overpass. Through the structure, the lifting point 21 (or the floor point 29) of the non-overpass bridge is arranged at the outer side of the ground auxiliary road vehicle lane e, so that the ground auxiliary road vehicle lane e can pass through the lower part of the non-overpass bridge, and the conflict point between the flow direction of the ground auxiliary road vehicle and the flow direction of the non-motor vehicle of the overpass bridge is eliminated.
The non-overpass bridge begins to bias inward at a location after the overpass vehicle lane lift point 22, merges with the overpass vehicle lane f above the crossing object 25, separates from the overpass vehicle lane f after crossing the crossing object 25 and biases outward. In this embodiment, the human non-overpass bridge begins to bias inward at a turn 23 near the ground-side motorway e, merges with the overpass motorway f at 24, and reaches a maximum vertical height above the mid-point of the crossing object 25 with the overpass motorway f. At the separation point 26, the non-overpass bridge separates from the overpass vehicle lane f and is biased outward until a turn 27.
Because the motorway and the manway bridge of the overpass bridge are branched under control, the overpass bridge can land on a longitudinal slope according to the specifications respectively. The landing longitudinal slope of the motor vehicle bridge can be 4%, and the cross-line bridge of the conventional technology needs to uniformly control the longitudinal slope according to people and not more than 3.5%, so that the motor vehicle bridge of the cross-line bridge can shorten the bridge length, and has better economical efficiency than the conventional technology.
The embodiment of the application also provides a method for designing the overpass bridge for eliminating traffic conflicts at the floor points, and other parts of the method are the same as the existing design method, and the differences are as follows: the method comprises the steps of designing a motor lane of a overpass bridge and a non-overpass bridge into air bifurcation, separating a lifting point of the motor lane of the overpass bridge from a lifting point of the non-overpass bridge, separating a landing point of the motor lane of the overpass bridge from a landing point of the non-overpass bridge, and arranging the landing point of the non-overpass bridge outside a motor lane of a ground auxiliary road so that the motor lane of the ground auxiliary road can pass through the lower part of the non-overpass bridge.
Further, in order to shorten the bridge length of the motor vehicle bridge, at least part of the longitudinal slope gradient of the motor vehicle lane of the overpass bridge can be designed to be 4%, so that the economy is better.
In summary, the embodiment of the application provides a overpass bridge for eliminating traffic conflicts at a landing point and a design method thereof, which can eliminate potential safety hazards from the root, effectively improve traffic safety, and have higher practical value and popularization value.
