【摘要】：对于高寒地区的面板堆石坝,水位变幅区面板的防结冰设计一直是个较难解决的问题。由于渗透作用,使渗水进入面板混凝土,在冬季低温情况下,面板迎水面和渗入面板的水同时结冰,造成面板和库面冰体连接在一起,在水位发生变化时,对面板产生很大的拖曳力,很容易造成面板损坏,长时间的冻融循环,加速了面板混凝土老化、碳化和开裂现象。本文通过新型防渗涂料HK-966在宝瓶水电站工程面板防结冰设计中的成功应用经验,对HK-966的防结冰原理及施工方法进行介绍,对高寒地区面板的防结冰设计提供了新的思路,其成功经验值得推广。
[Abstract]:For rockfill dam in frigid area, water level panel of anti icing design has been a difficult problem. Due to osmosis, the water seepage into the concrete slabs under the condition of low temperature, the surface and penetrate the panel panel panel caused by ice water at the same time, the ice surface and base body are connected together in the water level changes, produced great drag force on the panel, it is easy to cause damage to the panel, the freeze-thaw cycle long time, accelerated aging of concrete panel, carbonization and cracking phenomenon. Based on the HK-966 model in the treasure bottle of anti-seepage coating Hydropower Project panel anti icing in the design of successful application experience of anti icing and principle the construction method of HK-966, provides a new way to design anti icing on the alpine region panel, its successful experience is worthy of promotion.
