摘要
结合九畹溪大桥施工实例 ,详细介绍了采用缆索吊双肋悬拼钢管拱的新技术。该技术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。
Combined with the construction practice of Jiuwanxi Bridge,it introduces the new technology of suspended patching of double libs which are suspended by steel cable.The significant feature is that transfer the welding of the cross conjection from air to ground,which will gaurantee the safety of the construction and upgrade the installation quality.
