PROBLEM TO BE SOLVED: To provide a continuous wall excellent in low cost, strength and durability for reducing the discharge volume of sludge forming industrial waste. SOLUTION: This is a construction method of continuous wall formed by using a movable base machine 22 and a chain cutter system excavation device 21 provided with a cutter 26 for ditch excavating an objective ground. While excavating the objective ground, a powder material, a granular solidifier, the slurry material or the solidifier and the slurry material is discharged. The method consists of a first process for mixing and agitating the ground sand and soil in the ground with the solidifier, the slurry material or the solidifier and the slurry and a second process for discharging the powder material and the granular solidifier to the mud water mixed soil which is mixed and agitated by the first process and mixing and agitating the solidifier with the mud water mixed soil. The first process is performed by ditch excavating while the device 21 moves from a building location of the cutter 26 as a starting point in one direction and the second process is performed while the device 21 moves back to the building location of the cutter 26.
