摘要
结合赵家沟管线桥工程实例,对大跨度提篮式钢管拱管线桥结构的合理分段、钢桁架和拱肋节段的安装及合龙、拱脚与拱肋之间的临时连接、拱肋节段在临时支架上的支撑、拱肋节段之间的连接以及拱肋体系转化方案等加以阐述,以供同类工程参考。
Combined with Zhaojiagou pipeline bridge project, the reasonable segmentation of structure, installation and closure of truss and rib segments, temporary connection of spring joint and arch rib, support of rib segment in temporary support frame, connection between rib segments and conversion program of arch rib system were all expounded, which provides reference for similar projects.
