PURPOSE:To reduce the energy of tidal wave by breaking by a method in which the bottom plate and top plate of a cobble stone-filling box are projected forwards, and a U- or V-shaped separation wall is erected vertically between the projected bottom plate and top plate so that the tidal wave is separated, sheared, and collided mutually. CONSTITUTION:A floor plate 3 and a top plate 4 are projected on the front side of a cobble stone-filling concrete box 2, a separation wall 7 of a V-shaped cross section is erected between the floor plate 3 and the top plate 4, and spaces 5 and 6 are provided on the back and both sides of the separation wall 7 in order to form a revetment block F. The rubble 3 on the bottom under water is leveled off, the revetment block F formed on the land is installed by a crane ship, etc., without being filled with cobble stone 1, the cobble stone 1 is charged into the box 2, part of concrete for the top plate is placed, and then soil and sand are embedded on the back side of the box 2. |
