Instead of being piled up, they are laid side by side side by side on the seabed 40 apart from 2. In addition, the block 10
In order to fix to the block 10, a convex anchor portion may be provided on the lower surface of the block 10, and the blocks 10, 10 ... May be connected to each other via a wire or the like.

15 is rooted. That is, since the block 10 is formed of porous porous concrete rather than ordinary solid concrete, the seaweed 15 can be sufficiently rooted. Note that seaweed may be rooted on the surface of the block 10 other than the root housing portion 11. Also,
The root accommodating portion 11 may be filled with soil such as earth and sand or fertilizer.

Since it is below and cannot be seen from the ground or the sea, it does not destroy the natural scenery of the beach, and Block 10,
Since a large number of seaweeds 15, 15 ... Rooted in 10 ... serve as resistance to the flow of seawater, the energy of the waves can be reduced to calm the waves, thereby protecting the beach.

座礁を防ぐこともできる。As described above, the porous concrete wave breaker according to the present invention enables the roots of plants to be entangled in the block by forming the block from porous concrete having a large number of small voids. By rooting seaweed in this block and arranging it side by side on the bottom of the sea away from the shoreline, the energy of the waves can be reduced in the sea to calm the waves, and the coastline can be preserved without damaging the beach landscape. It can be carried out. It is also possible to prevent grounding if a ship or the like accidentally enters the installation site of the wave breaker.
