PURPOSE:To prevent the liquefaction of the ground by a method in which a treating machine with a stirring blade is penetrated into and drawn out of the ground while being turned, a solidifying chemical grout is injected through the treating machine to solidify the ground in a form of lattice, band, etc. CONSTITUTION:The stirring blade Pa of a deep layer mixing and treating machine P is penetrated into and drawn out of the ground 1 to be liquefied while being turned. During the penetrating period, a solidifying chemical grout is supplied and discharged in the neighborhood of the blade Pa with stirring to form improved ground 2, e.g., solidified latticed wall, banded wall, etc. A superstructure 3 is constructed on the improved ground 2. |
