摘要
昭平水电站施工导流分 3期进行 ,一期围堰又进行了两次 ,设计思想是减少断航时间 ,缩短工期。各期导流建筑物各异 ,施工方法也不相同。二、三期围堰采用下游围堰截流 ,围堰基础深覆盖层采用截水槽、高喷等方法处理 ,解决了渗漏大问题。由于导流标准偏低 ,有较大的风险 ,然而 ,由于施工期段的方法选择恰当 ,再遇上枯水年份 。
Construction diversion of the ZHS had three stages. The design thinking is to shorten navigation broken time and construction time. All the stages are different and so the diversion construction methods are different too. Because diversion standard is lower,construction had much risk. But for using correct construction methods and the construction year being a drought year, the diversion was succssful.
