Then, after driving the steel pipe sheet pile or the steel sheet pile, the head of the steel pipe sheet pile or the steel sheet pile is raised and connected by a tension member or the like. Thus, a portion corresponding to the outer circumference of the target structure is doubly surrounded by the steel pipe sheet piles or steel sheet piles that are cast in the front and rear. Then, the temporary cut-off is completed by filling the filling concrete between the steel pipe sheet piles or steel sheet piles before and behind this.
