Abstract

Un système de régulation de la pression des vagues et du courant de littoral, selon la présente invention, comprend : un cadre de brise-lames qui comporte une pluralité de plaques, s'étend dans la direction latérale et forme une pluralité d'espaces de remplissage; et un moyen de fixation pour fixer le cadre de brise-lames. La pluralité de plaques se chevauchent de manière à être parallèles les unes aux autres et les plaques adjacentes à une distance fixe dans le sens de leur longueur sont partiellement reliées les unes aux autres. Le moyen de fixation comprend : un cadre de fixation de treillis qui recouvre l'extrémité supérieure du cadre de brise-lames; et un câble de fixation qui est relié au cadre de fixation et qui est fixé au fond marin au moyen d'un ancrage de fixation. Le cadre de brise-lames fait partie d'une pluralité de cadres de brise-lames. Une partie des cadres de brise-lames peut être enterrée à proximité du rivage de façon à ne pas être exposée depuis le fond marin, et l'autre partie des cadres de brise-lames peut être disposée de façon à être exposée depuis le fond marin à un emplacement qui est éloigné de la partie des cadres de brise-lames vers la mer. Le système de régulation de la pression des vagues et du courant de littoral, selon la présente invention, permet de réduire l'érosion du fond marin à proximité du rivage par réduction de l'énergie des vagues, qui est l'influence des vagues, et contribue à préserver la plage par inhibition de la perte de sable sur le rivage.
