PROBLEM TO BE SOLVED: To provide a reinforcing structure of a revetment steel sheet pile shortening a construction period and reducing a construction cost while effectively achieving a reinforcing purpose without needing construction of new revetment steel sheet pile like a conventional example by constructing the reinforcing structure limited to an area in contact with vertical variation of a water surface. SOLUTION: The reinforcing structure of the revetment steel sheet pile 1 is formed using a channel steel sheet pile 1 having a center base 1a and right and left joint plates 1b formed bent at the right and left side ends of the center base 1a, and driving the channel steel sheet pile 1 into the water bottom ground 2 so that the crest faces and trough faces of the center base 1a are alternately continuous. A reinforcing plate 5 is provided over the crest face 1d of the center base 1a on the side in contact with the water surface 4, of the steel sheet pile 1, limited to an area from above the water surface 4 to below the water surface 4, and a reinforcing concrete layer 8 covering the whole reinforcing plate 5 and the water surface side surface of the steel sheet pile 1 are formed placed on the water surface side surface of the steel sheet pile 1, limited to the area from above the water surface to below the water surface.
