行われないという問題点がある。In the conventional method of constructing a breakwater structure by disposing the wave-dissipating block as described above, the circulation of seawater between the outer port and the inner port is not smoothly performed. Therefore, there is a problem that the water quality of the inner port deteriorates. In the case of a floating breakwater, it is possible to achieve a smooth circulation of seawater compared to the conventional method as described above, and it is economically possible to construct a breakwater at a lower cost than a breakwater block type breakwater structure. Although it has an advantage, there is a problem that the wave-dissipating action is not performed perfectly because the member is in a state of being floated on the water.

をなしている。At this time, as the anchor 70 to be used, a general pile anchor can be used,
It is also possible to use a separate anchor as proposed by the applicant. The separation type anchor proposed by the applicant of the present invention, when the water in the pile is discharged by the operation of the suction pile, the anchor is pressed against the sea bottom and penetrates into the sea bottom,
After the anchor has entered the seabed, the hydraulic jack is activated to separate the suction pile from the anchor.
