摘要
文章深入研究了钢箱梁顶推法施工技术,探讨了其在特大桥工程中的应用。顶推施工不需要使用大型起重机,但面临焊接式箱梁自重过大的问题,需将其顶入临时墩基础。文章重点强调了临时支撑体系设计及滑动轨道安装对顶推施工的重要性,总结了施工过程中的关键工艺,强调了技术实践和加固措施对工程质量的提升作用。
The construction technology of steel box girder incremental launching method is deeply studied,and its application in super-large bridge engineering is discussed.The incremental launching construction does not require the use of large cranes,but faces the problem of excessive self weight of welded box girders,which need to be pushed into the temporary pier foundation.This paper focuses on the importance of temporary support system design and sliding track installation to incremental launching construction,summarizes the key technologies in the construction process,and emphasizes the role of technical practice and reinforcement measures in engineering quality improvement.
