高压喷浆技术在黄石垄水库大坝加固中的应用

Using high pressure grouting technology for reinforcing Huangshilong reservoir

黄石垄水库大坝在坝底与基岩之间存在明显渗水现象,决定对坝基进行截渗处理。本文介绍了坝基截渗方案的选择,高压喷射灌浆的设计与施工等。检测结果表明,截渗效果完全满足设计防渗要求。

The geologic exploration shows that the seepage exists between the dam bottom and foundation rock. So the seepage water on the dam fundation should be controlled. The selection of impervious scheme, the design and construction of high pressure grouting technology are introduced in this paper. The inspection result indicates that the impervious effect is fully satisfied with the need of seepage control of the dam.
