PROBLEM TO BE SOLVED: To enhance seepage control performance by ensuring the property of following the movement of a revetment structure, and to enhance shear strength of joint parts of the revetment structure by effectively exerting shear strength of an impermeable seepage-control material which is infilled between the joint parts of the revetment structure, in terms of the revetment structure. SOLUTION: A revetment 11 is constructed by joining a plurality of caissons 12, which are provided in line on submarine ground 21, by means of the joint part 13; inward curved concave parts 31 are formed on the side surfaces of the respective caissons 12 facing each other; and the joint part 13, which is filled with asphalt mastic 36, is formed in an enlarged spaced part 34 which is formed by making the concave parts 31 face each other.
