Application of Double-fluid Grouting in Water-proof Curtain of Temporary Cofferdam

Abstract:

The double-fluid grouting is a type of the static pressure grouting. By the fast setting of the cement slurry and the accelerating agent in the formation pore and crack, the water-permeable proof of foundation soil is increased and the disadvantageous of sand flow and seepage are controlled. The double-fluid grouting was applied in the serious leakage part of water-proof curtain project in a pump room in Dalian with good effect of anti-seepage and waterproofing.
