洞坪水利水电枢纽工程原审批的施工导流方案中,2004年汛期采用导流洞+大坝底孔方案,因设计增加坝后消能建筑物,大坝优化后工程量有大幅度减少,这样取消大坝导流底孔因素变成必须和可能。通过公司的大胆决策,取消导流底孔,为消能建筑物施工赢得了施工时间,工程提前受益7个月,增加发电收入4200万元。 In the original construction diversion scheme approved by Dongping Water Resources and Hydropower Project, the scheme of diversion tunnel + dam bottom hole was adopted in flood season in 2004. Due to the design of post-dam energy-dissipation building, the dam construction volume has been greatly reduced, It is necessary and possible to cancel the dam diversion tunnel. Through the company’s bold decision-making, the diversion of bottom holes was canceled and the construction time was spent for the construction of energy-dissipating buildings. The project benefited in advance for 7 months and the generating income increased by 42 million yuan.
