The quality analysis and control of cutoff wall of double-plate vibration sinking-mold

The basic principle and construction technology of double-plate vibration sinking-mold are introduced.In order to improve the construction technique and the anti-seepage ability of the cutoff wall,a systemic analysis is carried out on various aspects concerning the quality of the vibration sinking double mold cutoff wall.Four factors affecting the cutoff wall quality are analyzed,including continuity,integrity,homogeneity and associativity.Corresponding effective control measures are put forward,including continuity control measures,integrity control measures,homogeneity control measures and associativity control measures.A quality control system is developed.Meanwhile,the quality test methods of the double-plate vibration sinking-mold cutoff wall are proposed,including visual examination,seepage testing and sample inspection.By comprehensive inspection,hidden engineering dangers can be discovered in advance,so that prevention measures can be adopted.
