“群孔复合、平压灌注”堵漏新工艺与工程实践

“Multiple Holes Repairing, Equilibrium Pressure Grouting”——New Technology and Engineering Practice of Leakage Treatment

介绍了一种"群孔复合、平压灌注"灌浆堵漏新方法,并结合某水电站导流洞堵头高压透水堵漏工程实例,系统阐述了该工艺应用于高压透水条件下的灌浆堵漏机理,以及所采用的灌浆材料、工艺参数、施工方法等,为类似高水头、大流量堵漏工程提供了全新的技术思路。

The article introduces a new leakage grouting method ＂multiple holes repairing, equilibrium pressure grouting＂, and it takes the leakage stopping work of the high pressure permeable diversion tunnel plug of some hydropower station as an example to explain the mechanism of this technology applied in high pressure seepage grouting. The article also provided grouting materials adopted, technological parameters, construction methods etc, and this kind of information can provide new technical ideas for similar high water head, high flow leaking stoppage projects.
