摘要
在已有的钢桁梁拼装施工技术中,从分段划分、组装、工装、拼装顺序、焊接变形控制及检测等方面进行研究。总结“单元件制造+单元件地面拼装为大节段+大节段总装+节点自适应顶推+分阶段检测验收”工艺在赣州蟠龙大桥项目的成功应用。
In the existing construction technology of steel truss girder assembly,through studies from the aspects of segment division,assembly,tooling,assembly sequence,welding deformation control and inspection,the technology of"single element manufacturing+single element ground assembly for large segment+large segment general assembly+node adaptive push+stage inspection and acceptance"is summarized,which has been successfully applied in the project of Panlong Bridge in Ganzhou.
