摘要
三板溪水电站溢洪道和泄洪洞均为预应力结构，通过采用真空灌浆试验的方法来检验浆体在锚索孔道中的密实度和饱满度，通过锚索真空灌浆试验证明，达到了设计要求，使以后的锚索孔道的灌浆施工质量得以保证。
The spillway and flood -discharging tunnel of Sanbanxi hydropower project are all prestressed structures. The method of vacuum grouting test is adopted to check the tightness and plumpness of the slurry in the anchor cable hole. The result proves the tightness and plumpness of slurry in the anchor cable hole has reached the design requirement, which ensures the grouting quality of the anchor cable hole in the future.
