| Abstract: | In order to meet the requirements of flood control of Pubugou Hydropower Station and to ensure the safe operation of flood discharging tunnel,the tunnel lining cracks are inspected and measured and the reasons for cracks are analyzed. Two sequence hole complex reinforcement grouting technique with polyurethane and hydrophilic epoxy grouting material are employed for repairing cracks. The repaired water discharging tunnel survived the test of large flood flow,which shows the good repair and operation. |
