呼和浩特抽水蓄能电站上水库冬季防护措施

Protected Measures of the Upper Reservoir of Hohhot Pumped-storage Power Station in Winter

为了防止呼和浩特抽水蓄能电站上水库冬季在静水位条件下结冰冻胀,破坏沥青混凝土防渗面板,在对库内结冰过程进行观察和分析后,结合国内其他工程越冬破冰方案和现场试验,采取水泵扰水的越冬防护措施,达到了将冰盖与库盆面板分离的防护效果。并就水泵的安装时间、破冰设施的布置等提出建议。鉴于水库库盆冰盖处理措施尚属探索试验阶段,本工程经验仅供参考。

In order to prevent the upper reservoir in the condition of the static waterlevel of hohhot pumped-storage power station, in winter asphalt concrete impervious faceslab will broken because of frost heaving, freezing process on observation and analysis inthe reservoir, combined with domestic engineering overwintering icebreaker project and fieldtests, the winter protection measures disturbance of water pump, achieved protective effectsof ice sheet and the reservoir face slab separation, which made recommendations oninstalled time of the pump, laid of broken installation etc. In view of the reservoir basinice treatment measures are still in the exploratory stage, the engineering experience is onlyin reference.
