摘　　要：针对新金清闸闸底板脱空区软基回填灌浆质量检测问题,采用基于微创可视钻芯法的回填灌浆质量检测方法对其进行质量检测。通过对芯样图片、孔内摄像进行观察分析,并分不同层段对芯样进行描述,结合孔内渗水上升速率测定成果,综合判断检测闸室的回填灌浆满足要求。Aiming at the quality inspection of soft foundation backfill grouting in the void area of the bottom plate of Xinjinqing Sluice,the backfill grouting quality inspection method based on minimally invasive visual core drilling method is used to detect its quality.Through the observation and analysis of the core sample picture and video monitor through the hole,the core sample in different layers are described.Combined with the measurement results of the rising rate of water seepage in the hole,it is comprehensively concluded that the backfill grouting of the detection sluice chamber meets the requirements.
