齐热哈塔尔水电站调压室防渗设计研究

Study on Impervious Design of Surge Chamber,Qirehatar Hydropower Project

齐热哈塔尔水电站调压室所处边坡位置围岩较差,如发生衬砌渗水,将对边坡稳定产生威胁,并危及坡下电站的安全。通过论证,制定了综合渗水处理的方案:采取了掺入纤维混凝土、加强灌浆以及采用预应力混凝土衬砌等方式,以保证调压室边坡稳定及电站厂房的安全。

The geological conditions of the surrounding rock of the slope where the surge chamber of Qirehatar Hydropower Project is exca-vated are weak.Once the lining leaks, the slope stability will be endangered.Furthermore, safety of the power plant at the foot of the slope will be threatened.Through demonstration, the following comprehensive scheme for seepage treatment is proposed：by application of the fibre concrete to be added, the strengthening grouting and the prestressed concrete lining, etc, the stability of the surge chamber slope and safety of the power plant are secured .
