Abstract (en)

Process and device for depositing loose material (19), such as sand, under water by feeding a mixture of water and material through a tube (12) or hose (21) towards the area of the bottom of the body of water, which tube (12) or hose (21) over a length which extends adjacent to the said bottom has a succession of outflow openings (13,22) the outflow capacity of which in total is substantially the same as the quantity of mixture per unit time flowing through the tube (12) or hose (21). The tube (12) or hose (21) may cooperate with downwardly extending flaps (16,16 min ,16 sec ,16'''), disposed over the top of the length of tube (12) or hose (21) provided with the outflow openings (13,22).The tube may be a funnel (32).
