PPROBLEM TO BE SOLVED: To provide a water cutoff wall body for cutoff, capable of facilitating, simplifying and shortening a diving operation and shortening a construction period. PSOLUTION: The water cutoff wall body for cutoff includes: a floor base 11 of a water cutoff structure installed in a surrounding wall shape on a pedestal provided under a water surface of a structure, an internal frame having columns 16 erected at a prescribed interval on the floor base 11, and a water cutoff wall composed of a plurality of division water cutoff plates 19 inserted or externally provided between the columns 16. By tightening means, at least one of parts between the floor base 11 and the division water cutoff plate 19 and between the column 16 and the division water cutoff plate 19 is tightened through sealants 20-1 and 20-2 for water cutoff, the sealant is compressed by the division water cutoff plate 19 which receives an external pressure by a water pressure, and thus a water cutoff effect is demonstrated.
