漫湾截流就是以尽快的速度将澜沧江堵断,叫河水让路,经已建好的1号导流隧洞宣泄,让出坝址河段,并在上、下游围堰的保护之下,清基浇注高度为126米的混凝土拦河大坝。我国第二大水电站,总装机容量150万千瓦的漫湾为坝后式电站。所以,截流是为建坝也是修电站关键的第一步。特别是在要求提前一年发电的条件下,能否按期截流关系甚大。倘若截流失败,则不仅工期不能缩短一年,而且还将造成几千万元的损
Manwan interception is to cut off the Lancang River as soon as possible, called the river to make way, has been built on the 1st diversion tunnel catharsis, let out the dam section of the river, and in the upstream and downstream cofferdam protection, clear base Pour concrete dam of 126 meters in height. China’s second largest hydropower station, with a total installed capacity of 1.5 million kilowatts of Manwan dam-type power station. Therefore, river closure is the key first step for dam construction. In particular, the demand for power generation a year earlier, whether the cut-off on schedule, a great relationship. If the closure fails, not only the duration can not be shortened by one year, but also will result in tens of millions of losses
