The Effect of Mixing Bit Dynamics and Structure on Uniformity of CDM Pile’s Body

Abstract:

Based on the analysis on the dynamics and the cutting & mixing mechanism, the paper explained that the main factors which effect mixing uniformity of deep mixing pile body are the horizontal rotary velocity of the blade and the vertical motion, and analysis was also made on the effect of structure of stirrer to mixing uniformity. The approaches and measures to improve mixing uniformity were put forward.
