桐子林水电站地质条件复杂，一期围堰基础覆盖层深厚、防渗面积大。设计采用了单排高喷灌浆，局部双排，并对部分不良地层增加了控制性灌浆。施工完成后，一期围堰高喷防渗墙防渗效果显著，可供其他类似水利水电工程防渗设计与施工参考。

The geological conditions is complex in Tongzilin HPP. As to the first stage cofferdam, the overburden layer of the foundation is very thick and the anti-seepage area is huge. High pressure jet grouting in single line and partially in double lines was adopted. Controlled grouting was used for some areas with bad condition. Good anti-seepage effect had been confirmed after the completion of construction. The design and construction experience can be a guidance for other water resources and hydropower projects.
