INRICHTING EN WERKWIJZE VOOR HET OPZUIGEN VAN EEN GRONDSUSPENSIE MET EEN TRANSPORTMEDIUM. |
摘要 |
<p>Dredging or suction of a soil suspension from the sea bottom is effected through a suction conduit connected with a suction head enclosure resting on the sea bottom, there concurrently being supplied to the suction head enclosure and through a separate conduit connected therewith a transport fluid under pressure. Transport fluid is separated from the soil suspension collected at the surface and recycled to the suction head enclosure. Thus the transport fluid flows in a substantially closed recirculating flow course and consequently pollution of the sea is lessened.</p> |
