Technology for quickly and transversely moving urban viaduct steel box girder
The invention discloses a technology for quickly and transversely moving an urban viaduct steel box girder, and belongs to the technical field of large-span viaduct steel box girder installing.The technology comprises the following steps that a pushing support structure is arranged, specifically, the pushing support structure is composed of a bearing beam and a temporary support, the bearing beam is subjected to hot rolling, and support standing columns are made of spiral welded pipes; the middle transverse struts and the middle inclined struts are connected into a whole through channel steel, the support standing columns avoid the station area below, and meanwhile components are fixedly connected. Due to the fact that the viaduct is located in the urban area range, optimization and refinement of the bridge installation technology are considered, safety is guaranteed, the construction period is shortened, and influences on surrounding traffic and personnel life are reduced.
本发明公开了一种用于城市高架桥钢箱梁快速横移的工艺，属于大跨度高架桥钢箱梁安装技术领域，包括如下步骤：布置顶推支架结构：顶推支架结构由承重梁及临时支架组成，承重梁采用热轧，支架站柱采用螺旋焊管，中间横、斜撑采用槽钢连接成整体，支架站柱避开下方车站区域，同时构件之间固定连接。本发明由于高架桥位于市区范围内，考虑对桥梁安装工艺的优化、细化，以求确保安全，缩短施工周期，减少对周边交通及人员生活的影响。
