丹江口水利枢纽施工导流采用分期围堰导流方式,在右岸11至17跨分别于86、89、90、91、公尺高程处设14个4M×8M 的底孔。这些孔口按闸门和孔口的封闭方式分成两组:一组是11至13跨6孔,称为低压堵水孔,在坝上游面底孔进口处采用滑动门,低水期封闭;另一组是14至17跨8孔,称为高压操作孔。除了在坝上游面底孔进口处同样布置堵水门外,尚在坝下游底孔出口处布置
Danjiangkou Hydro-junction construction diversion using staged cofferdam diversion approach, on the right bank of 11 to 17 across the 86,89,90,91 meters at the elevation of 14 4M × 8M bottom hole. These holes are divided into two groups by the way of the closing of the gate and the hole: one is 11 to 13 cross 6 holes, which is called low pressure water blocking hole, the sliding door is used at the entrance of the bottom hole of the upstream face of the dam, the low water phase is closed; A group of 14 to 17 across 8 holes, known as high-pressure operation hole. In addition to the upstream dam bottom hole at the entrance of the same layout of the water gate, it is still at the bottom of the dam outlet layout
