Construction method of cable-stayed bridge crossing multi-track railway marshalling station
The invention discloses a construction method of a cable-stayed bridge crossing a multi-track railway marshalling station, and relates to the technical field of bridge construction. Comprising the following steps that n sections of steel-concrete composite beam supports of a swivel section are assembled; mounting a full-circle slewing crane and a self-propelled protective shed; rotating to a designed position; the steel-concrete composite beam is spliced in a suspended mode; the third step is circulated till the whole bridge is closed, and bridge deck slab prestress tensioning and grouting are conducted; after the closure section is installed, the self-propelled protective shed is dismantled section by section through cooperation of a chain block and a full-circle slewing crane; the steel beam lifting station, the full-circle slewing crane and the temporary support are dismantled; constructing a bridge deck system and auxiliary projects thereof; tensioning the full-bridge stay cables for the third time to complete cable force adjustment; static and dynamic load test; and completing a vehicle. A support method, a horizontal rotation method and a cantilever method are integrated, the front n sections of steel beams are installed through the support method, the railway lines are crossed through horizontal rotation, the steel beams are installed through cantilevers till closure, and when the cantilevers are installed, a large-area self-propelled protective shed is utilized, and the safety of the railway lines below is guaranteed in an all-around mode.
本发明公开了一种跨越多股道铁路编组站斜拉桥施工方法，涉及桥梁施工技术领域。包括以下步骤：完成转体段n节段钢‑混组合梁支架拼装；安装全回转起重机、自行式防护棚；转体至设计位置；钢‑混组合梁悬拼；循环步骤三直至全桥合龙，进行桥面板预应力张拉、压浆；合龙段安装完成后用倒链配合全回转起重机将自行式防护棚逐段拆除；拆除钢梁提升站、全回转起重机和临时支撑；桥面系及其附属工程施工；全桥斜拉索第三次张拉，完成索力调整；静动载荷试验；竣工通车。本发明集支架法、平转法和悬臂法为一体，支架法安装前n段钢梁，平转越过铁路线，悬臂安装钢梁至合龙，且悬臂安装时，利用大面积自行式防护棚，全方位保证下方铁路线安全。
