New chemical grouting technology was used in the Three Gorges Project
mainly including the adoption of CW epoxy grouting to treat the fault zone;the use of chemical grouting with acrylate to treat curtain in fractured intensive zone
fault zone and strong weathering zone in which cement grouting can’t meet the need of seepage control;the use of epoxy slurry to treat the cracks of concrete surface and the structure interface joints
such as CW
LPL
EAA and so on.The chemical grouting in the Three Gorges Project obtains a good effect
