る。Further, if the caisson is formed into a hollow shape, the cost is reduced by saving the amount of concrete used to form the caisson, and the caisson is also lightened, making it easier to carry the caisson. After the caisson is installed in a predetermined location, the stability of the caisson can be improved by filling the cavity with sand or the like.
実施例
以下本発明の一実施例を図面に基づいて説明する。第１
図において、ケーソン１は波浪Ａに対向して配置されお

が拡縮している。EXAMPLE An example of the present invention will be described below based on the drawings. 1st
In the figure, a caisson 1 is placed facing a wave A, and a plurality of pipes 2 are provided passing through this caisson 1 in the front-rear direction. The tube 2 forms a water permeation hole 3, and the cross-sectional area of the flow path is expanded or contracted by a narrowed portion 4 formed inside.
以下、上記構成における作用について説明する。Hereinafter, the effects of the above configuration will be explained.
ケーソン１の前面に打ち寄せる波浪Ａは、透水孔３を通

のために、ケーソン１の背面側の水域における静穏性を
確保しながら、ケーソン１の前面側の水域と背面側の水
域との間に海水の交流が生じ、ケーソン１の背面側の水
域における汚濁が防止される。Waves A crashing on the front of the caisson 1 are discharged into the water area on the back side of the caisson 1 through the water permeable holes 3. At this time, the energy of the wave A is absorbed and dissipated by the expansion and contraction of the channel when it flows into and out of the water permeable hole 3. For this reason, while ensuring calmness in the water area on the back side of caisson 1, an exchange of seawater occurs between the water area on the front side of caisson 1 and the water area on the back side, causing pollution in the water area on the back side of caisson 1. is prevented.
また、第２図に示すように、ケーソン１は、前面壁体５
と背面壁体６との間を空洞部７に形成してもよい。Further, as shown in FIG. 2, the caisson 1 has a front wall 5
A cavity 7 may be formed between the front wall 6 and the back wall 6.
