摘要

The present invention relates to an excavation stirring rod used in the ground reinforcement method or the vertical water barrier method (for example, Excellent Soil Compoud Column ™ (hereinafter referred to as ESC ™ method)) using an expandable hardener and a deep mixing stirrer using the same. Preferably, the excavation agitation rod is improved so that the outflow of ITO is suppressed during excavation and stirring, and the improvement by excavation, mixing and agitation of the earth is carried out efficiently, and in particular, the arrangement of the excavation agitation rod adjusted so as not to form an unimproved portion.
