摘要(Abstract)：
论述了通过注浆在特大型垂向导水通道——陷落柱中建立人工“止水塞”的技术与途径，即“止水塞”位置选择、厚度计算、注浆钻孔的施工工艺、注浆施工工艺、“止水塞”检查、完善与加固方法，并通过实例说明该项技术的实用性和可推广性。
This paper expounds the technique building “concrete plug” in collapse column with grouting,i.e.selection of the place of “concrete plug”,calculation of the thickness,the technology of drilling and grouting,the methods of checking and consolidating “concrete plug”.The practicality and expansion are illustrated with an example.
