Abstract

La présente invention concerne un équipement de fixation pour un appareil de collecte de sable par balayage pour empêcher l'érosion côtière. Ledit équipement comprend: une pluralité de blocs de support qui sont disposés de façon à supporter un appareil de collecte de sable par balayage à partir du fond de celui-ci, et sont reliés l'un à l'autre par un fil de liaison; un cadre de fixation qui est placé sur l'extrémité supérieure d'une partie de remplissage de l'appareil de collecte de sable par balayage, et est relié au fil de liaison; et un mécanisme d'ancrage qui est fixé à chacun des blocs de support et est intégré dans un fond marin. Les blocs de support sont chacun formés de manière à avoir une surface inférieure ronde et une surface supérieure plate. Une tige de saisie est disposée dans un trou traversant vertical de chacun des blocs de support, et le fil de liaison est enroulé autour des tiges de saisie respectives des blocs de support. Le cadre de fixation et le fil de liaison liant les blocs de support sont liés l'un à l'autre par une pluralité de bandes de liaison. Le mécanisme d'ancrage comprend : un montant ayant une partie de crochet disposée sur son extrémité avant supérieure; un élément de cône configuré sur l'extrémité inférieure du montant; et une pluralité de pièces de butée pouvant être incurvées disposées sur la surface extérieure de l'élément de cône. Selon la présente invention, un phénomène de portance négative au moyen des blocs de support et un phénomène de résistance au moyen des mécanismes d'ancrage sont combinés, et ainsi la position d'installation de l'appareil de collecte de sable par balayage peut être fixée de manière stable.
