| Abstract: | Application of chemical grouting for repairing the cracks in concrete lining of Pandaoling tunnel by using the water soluble polyurethane composite grout will be intreduced in this paper. It includes the studies of technical schemes, grout and embed materials, method of chemical grouting and examining its efficiency. The results show that the cracks in the lining have been better filled with the chemical grouting and can stop up the seepage water. The repairig work can be satisfied the requirement of the owner. |
