Summary of the invention
The objective of the invention is to provide a kind of main span high variable short slope road overpass bridge, it reduces as far as possible strides high-shrinkage short bridge slope segment length, stride height by the variation of main span hole and tackle special Overheight Vehicles, not only ensure that the various vehicle smooth in intersection are without hindrance but also reduce place occupancy saving and stride the bridge building costs, and reduce consumption and pollution that the vehicle climbing brings.
The object of the present invention is achieved like this: the high variable short slope road overpass bridge of main span is made of main span hole, accessory cross hole and the section connection of bridge slope.Main span hole and accessory cross hole are put in bridge pier by bridge span and are crossed over road, and the main span hole is striden high limit and is made as and only is fit to common oversize vehicle by height, and accessory cross hole is striden height and is defined as and only is fit to dilly by height; Stride the height changeable device but the main span hole is equipped with, bridge can conveniently be raise or open; The main span hole connects low accessory cross hole and short bridge slope segment is crossed over the road crossing bridge that road constitutes ground, half heavy ground or is sunken to ground entirely.The high variable short slope road overpass bridge of main span is at usual traffic behavior, the main span hole is specialized in common oversize vehicle and is passed through, accessory cross hole is dilly and bicycle, walkway, realizes on the bridge that common oversize vehicle, dilly, bicycle and pedestrian take their own roads unblocked under the bridge.When idol has special Overheight Vehicles must be by bridge following time, carry out and temporarily stop that the bridge floor road vehicle is current to raise or open the main span hole, treat that Overheight Vehicles are through recovering later main span hole ortho states and bridge deck traffic immediately.
The high variable short slope road overpass bridge of main span is at the actual ratio of common oversize vehicle of road driving and dilly and the realistic situation of special Overheight Vehicles rareness, ingenious application bridge rising or unlatching variation are striden height and are tackled rare special Overheight Vehicles, reached the purpose that as far as possible reduces spanning high-shrinkage short bridge slope segment length, implement simple widely applicable getting twice the result with half the effort, can ensure fully that the various vehicle smooth in intersection are without hindrance, saving space significantly takies and the bridge construction cost, and long-pending month of reduction bridge floor year, tired thousands of vehicular traffics were twisted climb high bring huge consumption and pollution.
Description of drawings
Be described further below in conjunction with the basic structure principle and the typical exemplifying embodiment thereof of accompanying drawing this patent design:
