摘要
对于道路桥梁工程来说,其在正式施工阶段必须要重视对于施工质量的管理。施工质量与整体工程效益密切相关,是增加道路桥梁使用寿命的关键因素,决定其能否最大程度地发挥出自身性能。文章阐述了预应力钢绞线张拉程序及相关的计算方法,并从预应力的施工要点、孔道灌浆、钢绞线的选取以及保存等方面探讨了预应力张拉施工的注意事项,旨在为相关工作人员提供参考。
Road and bridge engineering into the actual construction stage,the site staff must strictly control the construction quality,in order to improve the overall efficiency of the project,and extend the service life of the bridge,give full play to its performance.This paper introduces the tension program of prestressed steel strand and the related calculation method,and discusses the matters needing attention in the construction of prestressed tension from the aspects of the key points of prestressed construction,grouting of tunnel,selection and preservation of steel strand,hoping to provide reference for the relevant staff.
