7月16日12:58,赣江石虎塘航电枢纽二期上游围堰顺利实现合龙,提前10天完成二期围堰二次截流目标。石虎塘航电枢纽工程23孔泄水闸分两期施工,一期施工的左侧7.5孔泄水闸于2011年4月完工并投入运行,目前已进入交工验收阶段,右侧15.5孔为二期泄水闸。今年3月,赣江进入汛期,为不影响赣江过流,确保工程及人员安全,已于3月7日将去年8月合龙的二期围堰主动降低过水,待洪水期过后再进行恢复。为争取更多的枯水施工工期,二期围堰已于七月初着手进行第二次截流,开始上下游围堰进占。随着石虎塘航电枢纽二期上游围堰超计划提前合龙,下游
At 12:58 on July 16th, the upstream cofferdam of the second phase of the Shihutang Navigation and Hydropower Project of Ganjiang River was successfully closed, and the secondary cofferdam closure of the second phase was completed 10 days in advance. The Shihutang Navigation and Hydropower Project has 23 holes of sluice gates constructed in two phases. The 7.5-hole sluice gate on the left side of the first phase was completed and put into operation in April 2011 and has now entered the phase of acceptance inspection. The 15.5 holes on the right side is Phase II Sluice gate. In March this year, Gan River into the flood season, in order not to affect the Gan River over-flow, to ensure the safety of engineering and personnel, on March 7 in August last year, the closure of the cofferdam initiative to reduce the second phase, to be carried out after the flood period restore. In order to strive for more dry construction periods, the second cofferdam started its second closure in early July and began to occupy the cofferdam. With the Shihutang aeronautic and two upstream cofferdam super-plan ahead of closure, downstream
