PROBLEM TO BE SOLVED: To provide a quality control method for a soil cement cut-off wall capable of controlling unconfined strength of soil cement by measuring stirring elapse time and temperature of soil cement based on a relational condition of the confirmed accumulated temperature and the unconfined strength. SOLUTION: In this quality control method for the soil cement cut-off wall, stirring of soil cement is started, elapse time of stirring is measured, and a temperature at a predetermined depth of the soil cement cut-off wall is measured at the same time to control unconfined strength of soil cement based on accumulated temperature composed of an accumulated value of the elapse time and temperature in the construction of the soil cement cut-off wall in order to grasp washing time of a hole wall in the soil cement cut-off wall securely and improve quality of the soil cement cut-off wall.
