摘要
简要介绍某地铁六号线上跨繁忙铁路干线连续梁顶推施工中的顶推总体方案,顶推施工中的顶推机构设置、顶推同步控制、永久墩及临时墩受力控制、顶推中线控制等关键技术,该技术工艺先进、安全可靠,值得进一步研究和推广使用。
This paper briefly introduces the overall scheme of trusting construction for continuous beam push out overcross- ing busy trunk railway, setting of pushing mechanism, the synchronous control of pushing, the pier stress control of perma- nent and temporary, and key techniques of middle control pushing. With its advanced technology, safety and reliablity, the technique is worth further study and popularization.
