[Prior Art] Currently In order to protect the natural coast facing the open ocean from erosion by waves, concrete caissons and concrete
Jetties and offshore breakwaters made of piled up flocks are generally used.
しかしなから、これらの突堤や離岸堤は、その設置水深

ある。However, these jetties and breakwaters have a limit to the water depth in which they can be installed, and are unsuitable for coasts with steep seabed slopes, or beaches with soft ground. Moreover, if the height of the jetty or offshore breakwater is higher than the sea level, it not only creates an aesthetic problem that tends to damage the natural scenery, but also obstructs the circulation of seawater and becomes an obstacle to seawater exchange. It is also difficult to apply it to marine recreation, aquaculture facilities, etc. that are expected in the future.

している。However, all of these wave-dissipating levees have complex structures and require diving work to the seabed for installation.
The installation work requires a great deal of effort, and the latter also has disadvantages such as the need for transportation to the site.

持手段１１は、図示したような張骨に限るものではなく
、浮体２の収縮を規制し得るものであれば如何なる構成
のものであっても良い。The floating body 2 has a cylindrical shape with different diameters at both ends, and is formed by forming a highly durable flexible membrane material 6 made of synthetic fiber, synthetic rubber, synthetic resin, etc. into a desired cylindrical shape.
Fiber-reinforced plastic (F, R, P,) at the appropriate position
By attaching ring-shaped support bones 7 and 8 made of a lightweight and durable material such as, and attaching a spiral elastic bone 9 made of the same material, it is configured to be expandable and contractible in the axial direction. Furthermore, when installing the floating body 2 in the sea,
In order to hold the floating body 2 in an extended state, the floating body 2 is provided with holding means 11 consisting of tension ribs removably stretched between inner or outer support bones 7.7 or 8.8. This holding means 11 is not limited to the tensioned ribs as shown in the figure, but may be of any structure as long as it can regulate the contraction of the floating body 2.

係留索３を結着すれば良い。Each support bone 7 of the floating body 2 is provided with a mounting part 7a for a mooring cable 3, one end of the mooring cable 3 is secured to each mounting part 7a, and the other end of these mooring cables 3 is common. is secured to a securing fitting 4a on a submarine anchor 4. This anchor 4 is a cast-in concrete anchor that is installed on the seabed by being thrown into the sea from a ship. In addition, when connecting the floating body 2 and the anchor 4 with the mooring cables 3 as described above, it is not necessary to tie the mooring cables 3 to all the supporting bones 7, and it is not necessary to tie the mooring cables 3 to the appropriate supporting bones 7 according to the applied wave force. All you have to do is tie the mooring ropes 3 together.

、これによって浮消波堤か構成される。[Structure with the above configuration] is constructed by releasing the holding means 11 and compressing the floating body 2 in the axial direction, folding it into a small size, transporting it to the installation site offshore of the coastline, and expanding and holding the floating body 2 at the site. By holding the floating body 2 in an extended state by the means 11 and putting it into the sea together with the anchor 4, the axis of the floating body 2 is aligned in the wave propagation direction (usually in a direction perpendicular to the coastline 12), as shown in FIGS. 1 and 2. ), the large diameter portion 2a is directed offshore, and one or more floating bodies 2 are installed in the sea at a desired depth from the sea surface, thereby forming a floating wave bank.

行の障害となることを回避することもてきる。In the floating wavebank, the wave energy is dissipated by the floating body 2 resisting wave phase fluctuations, so that the wave height is effectively attenuated. Furthermore, since the floating body 2 is installed in the sea, it does not damage the natural scenery, and by appropriately setting the installation depth, it is possible to avoid obstructing the navigation of ships.
上記浮消波堤には約５０％程度の消波効果か要求される
が、それを設置する場所毎に海岸線や海底の形状、水深

効果を得ることが可能である。The above-mentioned floating wave dyke is required to have a wave-dissipating effect of about 50%, but even if conditions such as coastline, seabed shape, water depth, etc. differ depending on the location where it is installed, it will not be possible to meet those conditions. By increasing or decreasing the number of structures 1 installed accordingly, it is possible to obtain a desired wave-dissipating effect.

The diameter D□ is 2 to 3 m, and the diameter D2 or D+/ of the small diameter part 2b
2~D+/10 m, 1/2~1/6 of length B or wavelength
Further, the submergence source d from the sea surface on the large diameter part 2a side of the floating body 2 is in the range of 1/10 to 1/2 of the water depth, and the minimum distance e between the floating bodies 2 is D1/2 to D1. It is preferable that there be.

こともてきる。また、このように浮体２を上下複数層に
設置する場合、上下の浮体２の向きは同しであっても逆
向きてあっても良い。Furthermore, the floating body 2 can be constructed in multiple layers in the water depth direction in the various manners described above. FIG. 4 shows a case where the upper layer and lower layer floating bodies 2 are arranged at the same position above and below, and FIG. 5 shows a case where they are arranged at the upper tool position. In this case, the upper and lower floating bodies 2 may be connected together as shown in FIG. Furthermore, when the floating bodies 2 are installed in multiple layers above and below, the directions of the upper and lower floating bodies 2 may be the same or opposite.

しである。FIG. 6 shows another embodiment of the structure, in contrast to the one shown in FIG. 1 in which the holding means 11 for holding the floating body 2 in an extended state is attached directly to the floating body 2. In the structure 21, such a holding means is not directly attached to the floating body 22, and both ends of the extensible floating body 22 are connected to the mooring line 2.
The difference is that the floating body 22 is connected to individual throw-in anchors 24, 24 by 3, and is supported separately by these anchors 24, 24 to restrict contraction of the floating body 22 in the axial direction. Therefore, the anchor 24.
24 constitutes a holding means. In addition, the floating body 22
This structure is substantially the same as that shown in FIG. 1, except that no holding means is provided.

こともてきる。The shape of the floating bodies 2 and 22 is not limited to the above-mentioned cylindrical shape in which both ends have different diameters and the diameter changes continuously; for example, as in the floating body 32 shown in FIG. In addition, it can be formed into any shape, such as a drum shape with a gradually smaller diameter in the center, or a drum shape with a gradually larger diameter in the center, or it can be formed into a cylindrical shape with a uniform diameter. I'll come.
