Low displacement effects of using internal pressure relief blade in cement deep mixing

Year: 2024

Type: article

Abstract: The CDM-EXCEED method is one of the machine-stirred deep mixing treatment methods (CDM methods) that improve soft ground by discharging cement slurry into the soft ground and rotating the stirring mixing blade. In this study, we focused on low displacement, which was regarded as a secondary effect of the internal pressure-relief blade, and measured the displacement in the ground using a new insertion-type inclinometer. It is clear that this method has less impact on the surrounding ground than the conventional machine agitation deep mixing method.
