摘要
大吨位、长跨径钢桁梁的架设技术在惯常施工技术指南、验收规范上多采用拖拉、顶推的方法,在具体实践中,面临复杂环境有诸多的限制,采用大吨位履带吊安全、快速、有效完成架设施工,是"四新"技术在工程实践中的一次应用,为相似工况下的钢桁梁架设具有一定的借鉴和指导意义。
The erection technology of large-tonnage and long span steel truss beam often uses pulling and pushing in the usual construction technical guidelines and acceptance standard. In the specific practice, there are many restrictions in complex environment. Using large-tonnage crawler crane to safely, rapidly and effectively complete erection construction is the application of ＂four new＂ technology in engineering practice. It has certain reference and guidance significance for the steel truss girder erection in similar conditions.
