Through type simply supported girder bridge structure suitable for improving clearance under bridge and construction method
The invention relates to the field of bridge engineering, in particular to a through type simply supported girder bridge structure suitable for improving clearance under a bridge and a construction method, the structure comprises two side longitudinal beams, and the height of the side longitudinal beams is 1/10-1/18 of the span of the bridge; the bridge deck slab is located between the two side longitudinal beams and connected to the bottoms of the side longitudinal beams, and the height of the bridge deck slab is 1/10-1/18 of the width of the bridge. The structure can meet driving and construction requirements, and for the conditions that a conventional simply supported girder bridge cannot meet the under-bridge clearance requirement, the elevation of a route where an overpass bridge is located needs to be raised, and even the overpass bridge is unconditionally built, due to the fact that the under-bridge clearance potential of the structure is large, route raising can be avoided, cost is effectively saved, and economic benefits are improved; the method has great social influence on convenience for people to go out and guarantee of driving safety on roads, has good application prospect, and is particularly suitable for transformation of existing bridges.
本发明涉及桥梁工程领域，具体提供一种适用于提升桥下净空的下承式简支梁桥结构及施工方法，结构包含两个边纵梁，所述边纵梁的高度为桥梁跨度的1/10‑1/18；桥面板，所述桥面板位于两个所述边纵梁之间，所述桥面板连接于所述边纵梁的底部，所述桥面板的高度为桥宽的1/10‑1/18。本结构能够兼顾行车和构造要求，对于常规简支梁桥无法满足桥下净空要求，需要抬高上跨桥梁所在路线标高甚至无条件修建上跨桥梁的情况，本结构由于拓展桥下净空潜力大，能够避免抬高路线，有效节省费用，提高经济效益，对便民出行、保障上下道路行车安全的社会影响重大，具有较好的应用前景，尤其适用于既有桥梁的改造。
