Abstract

Metodo relacionado al dragado hidraulico de sedimento desde el fondo del mar, el fondo de diques de agua y similares, que incluye un primer paso operativo donde se absorbe o bombea sedimento a traves de una manguera o tubo a un segundo nivel localizado por arriba de la superficie natural de agua utilizando la diferencia en la presion hidraulica entre la superficie natural de agua y el segundo nivel para proporcionar o mejorar la capacidad requerida de succion o bombeo. En el segundo nivel se recibe el sedimento en un recipiente accesible por equipo mecanico localizado en o sobre la superficie natural del agua, el recipiente desde el cual al menos parte del sedimento se puede remover por bombas convencionales per se o metodos convencionales de levantamiento o al liberar el sedimento a un nivel inferior.Method related to hydraulic dredging of sediment from the bottom of the sea, the bottom of water dikes and the like, which includes a first operational step where sediment is absorbed or pumped through a hose or tube at a second level located above the natural water surface using the difference in hydraulic pressure between the natural water surface and the second level to provide or improve the required suction or pumping capacity. In the second level the sediment is received in a container accessible by mechanical equipment located on or on the natural surface of the water, the container from which at least part of the sediment can be removed by conventional pumps per se or conventional methods of lifting or by release the sediment to a lower level.
