屋架预应力张拉和孔道灌浆施工质量控制

The construction quality control of roof prestressed stretch and duct grouting

结合某检修库工程实例,针对预应力张拉和孔道灌浆施工工艺,从方案选择、工艺数据计算、施工工艺和质量控制等方面进行了分析,介绍了屋架预应力钢筋的张拉和孔道灌浆的过程控制,从而保证施工质量。

Combined with an inspection storage engineering example,aiming at prestressed stretch and duct grouting construction process,which was analyzed from program choice,process data calculation,construction process and quality control.The roof prestressed reinforced bar stretch and duct grouting process control were introduced,therefore guaranteed construction quality.
