摘要
通过对常规孔口封闭灌浆法的孔口封闭器进行改造,使孔口封闭灌浆法也适应于低压帷幕灌浆工程,从而扩大了其适用范围,提高了工程质量,缩短了工程工期。
The packing gland for the conventional high-pressure grouting is modified to be adaptable to the low-pressure curtain grouting ; by which the application area of the grouting method is enlarged along with improved grouting quality and shortened construction period.
