摘要
针对大型跨街预应力天桥施工,以上海某大型跨街工程项目为依托,开展对跨街天桥的主体结构设计、高支撑模板排架搭设、预应力筋铺设和结构混凝土浇筑等技术方案研究,探讨相关技术的施工安全质量控制要点,为今后类似工程施工提供一定的参考。
Aiming at the construction of the large cross-street pre-stressed flyover,a large cross-street project in Shanghai is taken as the basis to carry out research on the technical scheme of the main structure design,high support formwork.row erection,pre-stressed tendon laying and structural concrete casting of the cross-street flyover,to discuss the construction safety and quality control points of related technology,and to provide certain reference for the construction of similar projects in the future.
