| Abstract: | In order to have a better understanding of chemical grouting,combining the concrete cracks handle engineering of Dahua Hydropower Station in Guizhou,the chemical grouting technical＇s application in water conservancy and hydropower,the process principle,the key technical measures and the construction methods of PSI-CW combination grouting were mainly introduced.Chemical grouting to handle the concrete cracks has many merits,such as the lower viscosity,the better hydrophilicity,and easier perfusion,and has bonding strength and better durability after the chemical grout hardening. |
