The leakage treatment measures for the No.3 diversion tunnel in Huanglongtan Hydropower Station are intro-duced.Based on the investigation of leakage scale and characteristics , a treatment scheme is adopted in which the ce-ment and chemical grouting are combined.Then, construction parameters such as the type , number and size of the grou-ting holes, grouting material and its mixing ratio , and the grouting pressure are determined.Safety measures for the fire control and occupational health during the chemical grouting process are also introduced.Experimental boleholes and the practical operation show that the leakage treatment is satisfactory.
