摘要
长阳西寺坪二级电站的地基自上而下依次为人工堆积碎石石渣层、黄泥包鹅卵石层、砂卵石胶结层、灰岩岩石。采用沉井法施工 ,沉井最大外径 2 5m。在沉井刃脚施工中 ,取消枕木支垫 ,采用自行设计加工的牛腿木模板。在沉井下沉过程中 ,对水平位移进行严格的控制 。
As the bedrock of Xisiping-Ⅱ mini-hydropower plant is covered by artificial crushed stones, mud coated cobbles, glued sand pebbles etc., so for the convenience of construction, the hydropower plant is designed as a cylindrical open cassion, its horizontal displacements are strictly confined during sinking course to dovetail the intake of cassion with the penstock of hydroturbine accurately.
