YUANHUA 2016 hot sale drilling drague for river sand mining
HOW DOES THE DSD WORKS?
All DSDs are equipped with a drill pole, the suction tube and water jet tube are attached to the drill pole. During dredging,DSD vertical move down the drill pole and rotates its drill , until the drill head digs into the sand layer of seabed, drill pole as a spud to lock the vessel into a stationary position. Then the water jet pump started, a high pressure water jet hits the sand layer to make high-tensity sand-water mixture, the dredged materials then sucked up and transported through a pipeline by dredge pump. The DSD will discharge the tailing to the disposal site via floating pipeline or hopper barges.
