摘要： PURPOSE:To accelerate the generation of whirlpool by arranging steel made cell structures in a straight line or zigzag at intervals and providing perpendicular walls vertical to the straight line linking the centers of cell structures adjacent to each other to the inside of a levee in the gap sections of the cell structures. CONSTITUTION:A permeable wave dissipation levee is built by arranging a plural number of steel-made cell structures 10 in a straight line or zigzag at required intervals. And, a perpendicular wall 14 is provided to the farther inside of the levee body than the straight line linking the centers of the steel made cell structures 10 vertically to the full height of the steel made cell structures. Accordingly, after the waves passing through the gap sections provided between steel made cell structures 10 adjacent to each other are once converged on the outside of the levee, when the waves spout into the levee, the whirlpool running in between perpendicular walls 14 generates. According to the constitution, the wave dissipation is performed by converting the energy of incident wave into whirlpool energy.

摘要： PROBLEM TO BE SOLVED: To provide an emergency correspondence type waveforebraking method which dies not impair a view, provides simple operation principle, and facilitates the maintenance and control by raising a steel pipe pile toward a water surface due to compressed air from the inside of a steel pipe sheet pile embedded in the ground bed on a sea bottom in such a manner that it blocks a harder entrance part. SOLUTION: Many steel pipe sheet piles 2 are embedded in such a manner that they block the ground bed G on a sea bottom of a harbor entrance part continuously. Next, each steel pipe pile 4 of which upper end is blocked by an intermediate lid member 10 is inserted and stored in the inside of each steel pipe sheet pile 2 in such a manner that each steel pipe pile 4 can move vertically, respectively. Furthermore, a compressed air in and out port is provided in a heat part of each steel pipe pile 4. Moreover, concrete for fixing pile 7 is placed below the inside of each steel pipe sheet pile 2, respectively. Then, when abnormal waves occur, compressed air is poured into the inside of the steel pipe pike 4 through the compressed air in and out port in the head part of the steel pipe pile 4, buoyancy is generated in the steel pipe pile 4, and it is lifted toward a water surface S so that each steel pipe pile 4 which floats continuously becomes breakwater. Consequently, it is possible to prevent the worsening of stillness in a port and facilitate the maintenance and control without necessitating large remodeling of the existing harbor entrance part.

摘要： PURPOSE:To form an artificial seashore with better circulation of seawater in an area where a steep gradient is led to the depths of the seawater by constructing a revetment made from caissons, having submerged slits, in a place in the sea at a fixed distance from land. CONSTITUTION:A revetment is constructed by continuously laying caissons 2 on a rubble mound 5 provided in a place in the sea W at a fixed distance from land 1. On the upper part of the caissons 2, a number of slits are bored through with at least the lowermost part of the slit placed lower than the seawater surface W.L. On back filling stones 6 laid in the land-side inside of the caissons 2, sand S is placed in an appropriate quantity, and an artificial seashore is formed thereby.

摘要： PURPOSE:To form an artificial seashore in an area where a steep gradient is led to the depths of the seawater by constructing a cellular block revetment in a place in the sea at a fixed distance from land with the upper ends of arc-shaped portions of the revetment made lower than the seawater surface. CONSTITUTION:In a place in the sea W at a fixed distance from land 1, a cellular block revetment is constructed of cells 2 made from steel plate cells with their arc-shaped portions 3 connected each other. The upper ends 3A of the arc-shaped portions are made lower than the surface of the seawater W.L. To the land-side inside of the revetment, an appropriate quantity of sand S is placed, and an artificial seashore is formed thereby.
