PROBLEM TO BE SOLVED: To provide a continuous wall construction method for building a good continuous wall by allowing the cutting of concrete end faces for accurate and good joint between a concrete placed in a preceding drilled groove and a concrete placed in a following drilled groove. SOLUTION: The continuous wall construction method comprises a step of using a drilling means B for drilling (Fig.2, not illustrated), a step of using the drilling means B for gripping a removal mounting means A having a removing means for removing sediment C and deteriorating concrete Cf (Fig.3, not illustrated), and a step of inserting the drilling means B gripping the removal mounting means A into the following drilled groove H2 for removing the sediment G and the deteriorating concrete Cf with the removing means D, N of the removal mounting means A (Fig.4, not illustrated).
