摘要
孔压注水试验是检测注浆质量的有效手段之一。以阳泉市307国道复线采空区治理工程工后检测为例,介绍了单管顶压止水栓塞封隔-阀式压水器组合检测技术中的检测设备、检测方法及检测效果。
Water pressing injection test is an effective way to check grouting quality. With the case of detection after construction of goaf treatment for double track of Yangquan section of national highway 307, the paper introduced test facilities, test methods and the effect of packer and water-press assembly.
