摘要
结合九畹溪大桥施工实例 ,详细介绍采用缆索吊分段双肋整体吊装钢管拱施工技术。其最大特点是将空中焊接横联作业转化为地面作业 ,能确保施工安全和拱肋拼装质量。
Based on the construction of Jiuwanxi Bridge, the paper describes the integral lift and assembly technology of steel tube arch in segment of double rib with cable crane. Its most outstanding characteristic is to transform transverse bracing welding from air to ground, thus securing construction and ensuring assembly quality.
