We have developed a deep mixing soil having a blade shredding in deep mixing soil method. In this paper, the test was carried out in the ground with a cohesive soil. As a result, I found the following. 1) By attaching the blade chopped into excavating agitator, mixing performance has been improved. 2) When set at 260 rpm cut number of times vane, it was found that in the horizontal direction and the depth direction, coefficient of variation is less than 30%.
