PROBLEM TO BE SOLVED: To provide a cut-off structure and its cut-off confirmation method capable of confirming cut-off efficiency. SOLUTION: The cut-off structure 10 is mainly constituted by playing such a central role as each cut-off material 17 capable of being covering a joint section 3 between concrete blocks 2a and 2b parallelling the longitudinal direction, a pair of first line stripe bodies 11a and 11b formed so as to project from the surface of the joint section 3 side of the cut-off material 17 and extended along the longitudinal direction of the joint section 3 and a pair of second line stripe bodies 12a and 12b projected from the surface of the joint section 3 side of the cut-off material 17 and extended along the joint section 3 in each outside of the first line stripe bodies 11a and 11b. The cut-off materials 17 are fixed to the concrete blocks 2a and 2b in the outside parts of the second line stripe bodies 11a and 11b. When the cut-off materials 17 are fixed, the cut-off efficiency of the cut-off structure 10 can be confirmed by applying pressure to each space formed between each of the first line stripe bodies 11a and 11b and each of the second ling stripe bodies 12a and 12b.
