摘要： PURPOSE:To make it possible to obtain high wave dissipation rate, to simplify execution and to reduce costs by providing wave dissipation inclined plates or two wave dissipation inclined plates stretching a net between the inclined plates to buoyant bodies tightened and moored to the foundation of the bottom of the sea. CONSTITUTION:Buoyant bodies 4 tightened and moored to the foundation 9 of the bottom of the sea with mooring ropes 10 are placed under the sea, and wave dissipation inclined plates 8 are provided on the buoyant bodies 4 at an interval. The wave breakage on slopes of the inclined plates 8 is made by a tight moor, and the wave dissipation is made by the obstruction of vertical direction water particle movement, so that the stability can be maintained. A steel pipe buoyant frame 11 tightened and moored thereto in the same way is placed under the sea, and a submerged inclined plate 13 and a semi-submerged inclined plate 14 are provided at an interval between steel pipe ports 12 rising to the buoyant frame 11, and a multi-layer wave current deepergizing net 15 is stretched between both inclined plates 13 and 14. The wave dissipation is made and, at the same time, the force of wave current is gradually reduced by the net 15.

摘要： PROBLEM TO BE SOLVED: To provide a wave force energy converter having a simple and efficient conversion mechanism and the function of considerably mitigating the wave force in abnormal waves, and reducing the life cycle cost until the transfer or withdrawal of the converter. SOLUTION: A floating type pressure-bearing plate 3 having a hollow float 7 movable in the vertical direction is disposed on a guide frame 11. The float 7 is moved in the vertical direction according to the wave condition, water is poured in the float 7, and the wave force on the floating type pressure-bearing plate 3 is adjusted. The guide frame 11 easily performs the transfer or withdrawal by a crane or the like via a suspension tool 5 provided on an upper end thereof. The floating type pressure-bearing plate 3 performs the oscillating motion with a passive shaft 17 as the axis, and the passive shaft 17 performs the reciprocal rotational motion. A revolving double ratchet mechanism 15 transmits the reciprocal rotational motion of the passive shaft 17 to a power- generating shaft 19 as the rotational motion in one direction.

摘要： PROBLEM TO BE SOLVED: To reduce cost by greatly reducing the quantities of concrete in wave dissipating works and a caisson upper section, and to obtain required wave- overtopping performance by the simple structure of a low top end without forming complicated structure such as slit structure in a caisson revetment or the like. SOLUTION: In a wave-dissipating concrete block covering hybrid type composed of a caisson 1 and wave dissipating works 2, an offing-side parapet 3, a retarding basin 4 and a land-side parapet 5 are installed successively to the upper section of the caisson 1 from the offing side, and the top-end height of the wave dissipating works 2 and the offing-side parapet 3 is set in height, in which waves can be driven into the retarding basin 4 in case of high waves. A caisson revetment or the like is formed in a low top-end, and driving-in waves (b) are captured and deenergized in the retarding basin 4 and an excellent wave-overtopping reduction effect is obtained.

摘要： PURPOSE:To improve calmness in an area behind an artificial island by arranging artificial islands at suitable intervals in the offing, attenuating the wave energy coming in through the intervals between the artificial islands into these intervals while the wave is dispersed at an outlet area by means of forming a calm area behind the artificial islands. CONSTITUTION:Artificial islands 1 are arranged in the offing leaving intervals 3. Each seabed between the artificial islands 1 is formed symmetrically in straight slopes 5 gradually climbing from center portion toward the artificial islands 1. A flat area 6 is then provided in the central portion of the seabed. A wave vanishing structure 11 is added onto the side of each artificial island 1. Thus the calmness in an area behind each island 1 can be improved flatly as a result of dispersing the wave at an outlet area as well as the wave energy coming in through the intervals between the artificial islands 1 can be attenuated.

摘要： PURPOSE:To relieve the force of earthquake by a method in which a hollow structure having spaces for equipment and ballast is connected to an anchor chain to connect it to fenders at mooring points and the tip of the chain is connected to anchors fixed to the seabed. CONSTITUTION:A rectangular or cylindrical structure 1 of hollow type, having spaces 3 for ballast on both sides of centered space 2 for equipment, is manufactured on dock. Under a condition that equipment 4 is mounted, it is towed to site, water ballast 5 is injected into the space 3, and the structure 1 is installed directly on the ground 6. Mooring points 8 are formed on the lower end of the side wall 1a of each corner of the structure 1 and connected to anchor chain 10 in the outside direction of the diagonal extended line by shackle 9, and the end portion of anchors 12 is connected to the tips of forked anchor chain 10 through concrete sinkers 11. Rocking movement as the case with floating structure against tidal differential can thus be eliminated.
