Curtain grouting quality inspection for dam foundation of Duopang Reservoir
Located in a karst developed area of Debao County in Baise City,Duopang Reservoir is a medium-scale reservoir constructed by blocking the underground karst channel with curtain grouting.The quality of curtain grout-ing was inspected by point detection and surface detection technology of conventional borehole pressure water test combined with electromagnetic CT.The results of inspection demonstrate the quality of curtain grouting for three holes of JZK3,JZK6 and JZK8 satisfies the design requirements,while that for the rest 10 holes does not meet the design requirements.
