8月3日,“是一个对世界水电发展史有重要影响的日子”。经过全体建设者6年的精心筹备和日夜奋战,装机规模仅次于三峡工程、在建规模世界第1的白鹤滩水电站主体工程全面开工,金沙江将再添1座108MW级巨型水电站。由水电十四局承担施工的左右两岸8座尾水调压井,以其规模宏大、工艺精湛引发业内专家和同仁的首肯——8个圆筒式尾水调压室,直径43~48m为世界已建跨度最大调压室,8座尾水调压室(井)开挖,遇到的最大难题,当数“桂状节理玄武岩(如橡筋捆筷子)特殊地质条件下的处理工艺”地形地质条件复杂程度、施工技术难度在水电建设史上首屈一
August 3, “is a day that has a significant impact on the development history of the world’s hydropower.” After 6 years of careful planning by all builders and day and night preparations, the scale of installed capacity is second only to that of the Three Gorges Project. The construction of the main project of Baihetan Hydropower Station, which is under construction in the world scale 1, is under full operation. An additional 108MW-class giant hydropower station will be added to the Jinsha River. Eight hydropower tail-water surge wells on both sides of the left bank and right bank, which are under construction by the Hydropower Bureau, triggered the approval of industry experts and colleagues with its large-scale and exquisite workmanship - eight cylindrical tailrace surge tanks of 43-48 m in diameter The world has been built span the largest surge chamber, 8 tail water surge chamber (well) excavation, the biggest problem encountered when the number of “basalt (such as elastic bandage chopsticks) special geological conditions of the processing technology ”Topographic and geological conditions of complexity, construction technology difficulty in the history of hydropower construction is first in the world
