摘要： PURPOSE:To increase wave breaking effect of a wave by forming a bag body which is bent upward with a sheet of a flexible material, filling this bag body with fluid so as to make it in the convex shape, and providing a movable body which is capable of rotating or oscillating in the bag body. CONSTITUTION:A flexible mound 1 is generally constituted by forming a bag body 2 with a flexible material and by filling it with fluid 3 such as sea water, water or the like. And the bag body 2 is formed by a material such as a vinyl chloride sheet and its bottom sheet 2b is held flat and its upper sheet 2a is held in the shape of an upward bent convex. Then, a movable body 4 of a rotor 5 constituted by a rotor wing 5a formed by a rust resistant material and an axis rod 5b is provided in capable of motion at almost the center of the bottom sheet 2b in the bag body 2. By this, arrival of a wave rotates or oscillates the rotor 5 so as to generate a turbulent flow and to damp energy, whereby demonstrating wave breaking effect of the wave.

摘要： PURPOSE:To make a complex wave dissipating effect securable through a relatively simple structure by erecting a Y-shaped vertical plate, expanding wide along the passing direction of an incident wave, on a horizontal plate being set up under the water surface, and constituting a wave dissipating unit thereat. CONSTITUTION:Plural numbers of wave dissipating units 10 constituted of a horizontal plate 12 being set up under the water surface and a Y-shaped vertical plate 14 being erected on this horizontal plate 12 in projecting one part on the water surface, are set up side by side with a support structure 16. In this horizontal plate 12, one end at the side of an incident wave X is formed into a semicircular form in a state of being set up, while the vertical plate 14 is made up of a base 14a on a straight line to be situated at the side of the incident wave X and a V-shaped part 14b leading to the rear of the base 14a. In addition, the base 14a is tightly installed on a longitudinal axis of the horizontal plate 12, while this V-shaped part 14b is tightly installed on the horizontal plate 12 so as to expand the interval width gradually along a passing direction of the incident wave X.

摘要： PURPOSE:To enable stable and high-efficient construction works of wave breaker, by fitting a water chamber having slits on its front side, into a steel cell, charging a packing material into the steel cell and then constructing a bottom floor of the water chamber. CONSTITUTION:A steel wave-breaker cell 10 is provided on its front or sea side with vertical slits 12 into which a steel frame member having rectangular shape in section is fitted. On the rear side of the slits 12 is formed a water chamber 14 which communicates through the slits with the outside of the cell. The steel cell 10 is filled with packing material up to the level of the bottom of the water chamber 14. While the packing material is continuously charged into the upper portion of the cell 10 except for the space defined by the water chamber 14, a floor bottom 15 of the water chamber 14 is concrete-placed under water-immersion condition. This permits safe concrete-placing works having a high efficiency.
