和静县小山口二级水电站引水渠道临近开都河。针对引水渠道地下水水位高,防止扬压力对渠道衬砌板的破坏,采用暗管排水降低地下水位的方式,进行排水减压。通过工程的实施,对于类似渠道防渗工程排水减压提供一定的借鉴经验。
Hejingxian Xiaokou two hydropower station diversion channel near the open river. In view of the high groundwater level of the diversion channel and the prevention of the damage of the uplift pressure on the channel liner board, the underground pipelines are drained to reduce the groundwater level for drainage and decompression. Through the implementation of the project, it can provide some reference experiences for drainage and decompression of seepage control projects of similar channels.
