の下方に網などを吊り下げたりして構成されている。[Prior Art] As is well known, floating structures such as floating piers, floating breakwaters, floating fish reefs, aquaculture cages, and aquaculture rafts installed in the ocean, ports, rivers, lakes, etc., are used as buoyant bodies to float them. Drums, hollow FRP or steel boxes, and urethane foam are used. That is, in addition to mooring the buoyant bodies in succession, each buoyant body is connected to each other using lobes, wires, etc. For example, in the case of a floating pier, a wooden plate or a steel plate is stretched over the top surface, or in the case of an aquaculture raft, the buoyant bodies are connected to each other using lobes, wires, etc. It is made up of hanging nets, etc. below.

できるようにされている。[Means for Solving the Problems] The present invention has been made to eliminate the drawbacks of the conventional buoyant bodies as described above. A wave-dissipating structure is constructed by packing a large number of floating spheres made of synthetic resin, rubber, or metal. The floating spheres are filled in a net-like bag or frame to a volume/rate of 40 to 70%, so that they can freely flow within the bag or frame when subjected to transverse waves or human waves. .

る。Among the floating spheres filled in a net-like bag or frame, those with a specific gravity of 1 F or more will float at the top of the bag or frame and have a specific gravity of 1 F.
Those nearby are floating in the middle, and those with a specific gravity of 1 or more are floating at the top. These floating spheres are a mixture of several types of objects with different specific gravities and are filled with a volume ratio of 40 to 70%, so when floating on the ocean, in a port, or in a river, the energy of the waves is absorbed by each floating sphere. Pass between floating spheres while moving, colliding, and rotating. This converts all the energy of not only surface waves, but also transverse waves and human waves, into the kinetic energy of the floating sphere, which greatly absorbs and attenuates incoming wave energy, exerting a wave-dissipating function.

る。FIG. 1 is a perspective view of an embodiment of the present invention, cut away at the - section, and reference numeral 1 in the figure represents a wave-dissipating structure. The wave-dissipating structure 1 includes a net-like bag or a cylindrical frame 2 made of Plus Deck, in which a large number of floating spheres 3a, 3b, and 3c with different specific gravities are stuffed, and a plurality of metal rings on the outer peripheral surface of the bag or frame 2. 4.4.4 and bars 5.5.5 are provided for reinforcement.

．． Several types in the range of 3 are used. For example, the floating sphere 3a has a specific gravity of 0.7, the floating sphere 3b has a specific gravity of 1, and the floating sphere 3

Furthermore, in addition to blow molding and foam molding, injection molding of hemispheres made of resin such as ABS and joining these hemispheres to form hollow spheres, or molding by mixing balloons with a specific gravity of about 0.2, is also possible. It doesn't matter if it's something. Floating sphere 3C contains metal powder, sand, and other inorganic specific gravity adjusting materials from 0 to

るため、十分な消波機能が得られない。Among these floating spheres, those with a specific gravity of 1 or less float to the top of the bag or frame 2, as shown in Figure 2, those with a specific gravity of around 1 float in the middle, and those with a specific gravity of 1 or more float to the bottom. . The floating spheres 3a, 3b, 3c are filled in the bag or frame 2 at a volume ratio of 40 to 70% depending on the strength of the waves. Volume ratio 70%
If this is the case, the free movement and rotation of the floating sphere will be inhibited, and a sufficient wave-dissipating function will not be obtained.

各浮遊球体の間隙に沿って流れたり、分岐しながら浮遊
球体間を通過する。When this wave-dissipating structure 1 is floated in the ocean, a port, a river, etc., waves such as surface waves, transverse waves, or human waves collide with the floating spheres 3a, 3b, 13C1, as shown by the arrows in FIG. As the floating spheres collide and move, they flow along the gaps between the curved floating spheres and pass between the floating spheres while branching.

ゆる返し波の発生を大幅に減することになる。During this passage, the energy of the waves is converted into the form of the motion of the floating sphere, so the waves are significantly attenuated, and beyond the wave-dissipating structure in the direction of wave travel, the waves change to a quiet flow with almost no waves. . Further, as mentioned above, since the waves enter and pass between the floating spheres, there are few reflected waves (dashed line in FIG. 2), and the occurrence of so-called return waves is greatly reduced.

て詰め込んでもよい。In the above embodiment, the shape of the wave-dissipating structure is cylindrical, but there is no problem with it having a pentagonal or square cross section.
The floating spheres do not have to have the same diameter, but may be packed in mixed sizes.

る。[Effects of the Invention] As described above, the present invention has a wave-dissipating structure by filling a net-like bag or frame with a large number of floating spheres with different specific gravities. Instead, the energy of waves such as transverse waves and human waves is attenuated when they pass between each floating sphere, so the wave dissipation effect is large. Furthermore, when the bag body or the hollow body is made of synthetic resin, there is no risk of rust or corrosion, and the buoyancy body can be provided at low cost.
