双层钢桁桥原位大修施工组织及安全管理

Construction Organization and Safety Management in In-situ Overhaul of Double-deck Steel Truss Bridge

以上海松浦大桥原位大修为工程实例,针对大桥在改造过程中需保障过江非机动车通行正常,同时大桥邻近运营中的金山铁路,且上跨黄浦江航道,施工组织及安全管理难度极大等难题,项目实施中采用了多阶段的总体施工组织及多项安全措施,有效保障了项目顺利实施,可为类似项目改造提供经验。

Taking the in-situ overhaul of Songpu Bridge in Shanghai as an engineering example, aiming at the problems that the reconstruction of the bridge is required to guarantee the normal traffic of the non-motored vehicles crossing the river, the bridge is adjacent to Jinshan Railway under operation and spans the channel of Huangpu River, and the construction organization and safety management are difficult, overall multistage construction organization and multiple safety measures are taken in the project implementation effectively to guarantee the smooth implementation of the project, which can be referred for the reconstruction of the similar projects.
