Summary
[edit]DescriptionDrague suceuse à désagrégateur (3).JPG |
Français : Une drague suceuse à désagrégateur est un engin mécanique flottant qui enlève la vase au moyen d’un désagrégateur rotatif appelé « élinde » positionné à l’ extrémité d’un long bras articulé. Le matériau enlevé est dilué avec de l’eau puis est retiré par le tuyau d’ aspiration. Ensuite il est évacué par une conduite de déversement vers un lieu de stockage de la vase sur la berge. Une drague suceuse à désagrégateur est également appelé « stationnaire » car elle n’ est pas motorisée. Elle peut se déplacer relativement à l’aide de ses deux pieux qui sont articulés et qui lui servent d’ encrage durant les travaux . En revanche, pour les déplacements importants un remorqueur est nécessaire. La drague stationnaire est principalement utilisée pour draguer les ports et curer au pied des quais. Elle a cependant le défaut d’ être sensible à la houle et aux vagues.
