この発明は、港湾内あるいは航路の水面を静穏にしたり
、港湾内の水質を維持および保全したシするために使用
する透過型消波壁に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a transparent wave-absorbing wall used to calm the water surface in a port or a shipping route, and to maintain and preserve the water quality in a port. It is something.

陸側消波部材４を支持構造物５における支持板乙に固定
した構造の消波壁が知られている。Conventionally, as a transmission type wave-absorbing wall, as shown in Fig. 28,
A plurality of offshore wave-dissipating members 5 made of steel pipes extending in the horizontal direction are arranged side by side at intervals in the vertical direction, and a plurality of land-side wave-dissipating members 4 made of steel pipes extending in the transverse direction are arranged side by side at intervals in the vertical direction. The side wave-dissipating members 5 are arranged side by side at intervals in the vertical direction on the land side, and the land-side wave-dissipating members 4 are arranged so as to face the gap between adjacent offshore wave-dissipating members 5. A wave-dissipating wall having a structure in which a wave member filter and a land-side wave-dissipating member 4 are fixed to a support plate A of a support structure 5 is known.
しかるに、前記従来の透過型消波壁の場合は、波が各沖
側消波部材５および各陸側消波部材４の間を単に屈折し
ながら透過するだけであるので、透過波が大きくなって
港湾内あるいは航路の水面静穏度の確保が困難になる。However, in the case of the conventional transmission-type wave-dissipating wall, the waves simply pass between the offshore wave-dissipating members 5 and the land-side wave-dissipating members 4 while being refracted, so the transmitted waves become large. Therefore, it becomes difficult to ensure water surface calmness within the port or along the shipping route.
沖側消波部材３および陸側消波部材４の間隔を小さくす

とができるが、何れにしても波エネルギーの減衰という
面からみると、消波壁を透過する水の流れが比較的スム
ースであり、コストが高くなる割にはメリットが少ない
という問題が生じる。The transmitted waves can be reduced by reducing the distance between the offshore wave-dissipating members 3 and the land-side wave-dissipating members 4 or by increasing their number, but in either case, from the perspective of wave energy attenuation. The problem arises that the flow of water passing through the wave-dissipating wall is relatively smooth, and that there are few benefits compared to the high cost.

等の効果カニ得られる。According to this invention, nine waves collide with each offshore wave-dissipating member 1,
Since the waves flow toward the land side along the uneven surface of each offshore wave-dissipating member 1 and collide with each other, the wave energy is attenuated, and the waves that pass between adjacent offshore wave-dissipating members 1 then move toward the land side. The wave hits the wave-dissipating member 2 and is reflected toward the oil side, and the reflected wave collides with the incident wave that has passed between the adjacent offshore wave-dissipating members 1 toward the land side, so that the wave energy can be further attenuated. Therefore, it is possible to effectively attenuate wave energy with a transmission type wave-breaking wall having a simple structure, and also to reduce reflected waves, transmitted waves, and overtopping waves.
