<p>The system distributes spoil such as dredged sand over a site so as to raise its level, the spoil being delivered via a stationary pipe, to whinch a number of distribution nozzles, spread over the site, are connected. After the desired level has been reached, some at least of the nozzles are moved to new positions. A number of nozzles (6) are coupled to a common feed pipe and mounted on movable supports (10, 13). when the desired level is reached at one section of the site, they are moved as a complete unit to the next one. There can be a discharge truck, on which a number of nozzles are mounted, this being connected by a flexible hose (2) to the supply pipe.</p> |
