摘要
在城市桥梁建设中,由于受周围环境、交通组织、施工场地及其它基础设施的限制,大跨度的箱梁无法用吊车及架桥机架设。桅杆吊装具有结构轻巧、安装方便、操作简单、安全可靠、经济合理等诸多优点,在大跨径梁体吊装中值得借鉴。结合工程实例,推广应用桅杆吊装施工技术,为同类工程施工提供依据。
In the construction of urban bridge,the long-span box beam cannot be erected by crane or bridge erection machine because of the limitation of the surroundings,traffic organizations,construction sites and other infrastructures.Due to many advantages of light structure,convenient installation,simple operation,safety,reliability,economy and rationality,the application of mast hoisting is worth learning in hoisting of large-span beam structure.The paper introduces the popularization of the mast hoisting construction technology by engineering cases,and provides the bases for the construction of the similar projects.
