摘要
运用箱梁桥竖向预应力无损检测方法,分析了影响竖向预应力精轧螺纹钢张拉力不足的原因,总结了影响竖向预应力张拉质量的具体施工技术要点,有效提高了精轧螺纹钢筋竖向预应力体系的施工质量。
This paper applied box girder bridge vertical prestress nondestructive detection method,analyzed the insufficient tension reason influenced vertical prestressed fining twisted steel,summarized the specific construction technology key points effected vertical prestress tensioning quality,effectively improved the construction quality of fining twisted steel vertical prestressing system.
