PROBLEM TO BE SOLVED: To provide a construction method of a slurry solidified wall enabling highly accurate construction of the slurry solidified wall even at a site having a narrow facility yard for a slurry plant. SOLUTION: A device for supplying a slurry solidifying material having an agitator is brought down to a deepest part of an inside of an excavated hole filled with the slurry. After supplying the amount of slurry solidifying material to be used for a predetermined area, the slurry and the slurry solidifying material is agitated by the agitator at the position for a predetermined time. Then the device for supplying the slurry solidifying material is lifted up by the height of the predetermined area. Further, after supplying the amount of slurry solidifying material to be used for a predetermined area again, the slurry and the slurry solidifying material is agitated by the agitator at the position for a predetermined time. Then the device for supplying the slurry solidifying material is lifted up by the height of the predetermined area. The procedures are repeated until the whole length of the excavated hole is covered, or the agitator is moved up and down for agitation for the whole length of the excavate hole, by which the construction method of the slurry solidified wall is provided as a basis.
