| Abstract: | For Nuozhadu hydropower station,its spillway is characterized by large discharge,high head and high velocity flow,the finish area of chute section floor is large,and high quality is required for floor smoothness.Based on the above features,specific construction scheme is adopted and management is strengthened in respect of slip form,surface finishing and protection technique so that the smoothness meets the design requirements,which provides references for similar projects. |
