清河电厂零号机取水口是我国第一个采用岩塞爆破法修建的取水口。它从1971年爆破成功迄今已安全运行17年。在清河电厂采用岩塞爆破之后,镜泊湖水电厂,丰满水电厂等其它水利水电工程也相继采用岩塞爆破法修建取水口获得成功,这说明岩塞爆破在已经建成的水库或江、河、湖、海具有岩石岸的深水区修建取水口在技术上是可行的。本工程经济效益也
The intake of the No. 0 unit of Qinghe Power Plant is the first water intake built in China by rock plug blasting. It has been safe for 17 years from the successful blasting in 1971. After the Qinghe Power Plant adopted the rock plug blasting, other water conservancy and hydropower projects such as Jingbohu Hydropower Plant and Fengman Hydropower Plant also successively adopted the rock plug blasting method to build the water intake. This shows that the rock plug was blasted in the already built reservoir or river and river. It is technically feasible to build water intakes in deep water areas where lakes and seas have rocky shores. The economic benefits of this project are also
