路を容易に形成することが出来る。Effect In the above configuration, the cross-sectional area of the flow path in the through hole is changed by narrowing and expanding due to the narrow passage portion.
Waves flowing into the through hole through the opening facing the wave propagation direction undergo a pressure loss and are attenuated and dissipated by reducing the flow pressure. Therefore, wave dissipation occurs within the through-hole, so no wave splash is generated, and as waves pass, flow is generated within the through-hole, which prevents organic matter from rotting due to stagnation and the generation of bad odors. Prevented. In addition, a channel whose cross-sectional area narrows and expands is formed by placing a narrow section in the middle of a tube with a uniform cross-sectional area, fitting the tube at both ends. A shaped flow path can be easily formed.

配置されている。Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings. In FIG. 1, a wave dissipating block 1 is formed by providing concrete 3 around a cast pipe 2 with a uniform cross-sectional area, and a through hole 4 is formed in the cast pipe 2 in the axial direction. At the same time, it is arranged with one end opening facing the direction of wave propagation. Also,
Inside the through hole 4 , a narrow passage 5 having a narrower cross-sectional area than the through hole 4 is formed by a narrow passage portion 6 . The narrow passage portion 6 forms a narrow passage 5 on the inner periphery,
The openings 6a and 6b at both ends are fitted externally to the casting tube 2.

流路を容易に形成することが出来る。 Hereinafter, the effects of the above configuration will be explained. First, waves 7 propagating toward the wave-dissipating block 1 flow into the through hole 4 through the general opening. The waves 7 that flowed into the through hole 4 are
When passing through the narrow passage 5 of the narrow passage portion 6, the wave is attenuated and dissipated due to a change in the cross-sectional area of the flow passage. Therefore, since waves are dissipated in the through hole 4, the generation of wave splash can be prevented, and since a flow is generated in the through hole 4, the decay of organic matter and the generation of bad odors due to stagnation are prevented. . Moreover, by arranging the channel whose cross-sectional area narrows and widens and changes, by arranging the narrow passage part 6 in the middle of the cast pipe 2 whose flow channel cross-sectional area is uniform, by fitting the channel into the cast pipe 2 at both ends. Therefore, a flow path having a predetermined shape can be easily formed.

路を容易に形成することが出来る。Effects of the invention As described above, according to the invention, wave dissipation occurs within the through-hole, so generation of wave splash can be prevented, and the flow generated inside the through-hole as waves pass through can be prevented. This can prevent the decay of organic matter and the generation of bad odors due to stagnation. In addition, a flow path having a predetermined shape for wave dissipation can be easily formed by simply arranging the narrow passage portion by fitting it into the pipe at both ends.
