摘要 |
A dredging apparatus is described for removing sediments from a bed of an expanse of water, comprising: a suction apparatus including a) a submersible pump including: a housing body provided with an inlet mouth and with a discharge opening and an impeller rotatably supported in the body between the inlet mouth and the discharge opening and rotatably driven by a respective driving device; and b) a suction head associated to the inlet mouth of the housing body of the pump and provided at the bottom with a suction opening of the sediments; wherein the suction opening of the head has a value of the cross-section area dimensioned to achieve in the working range of the pump a suction speed capable of removing the sediments by means of the fluid dynamics removal action carried out by the water sucked into the head. The invention also describes a dredging method which may be carried out by means of such an apparatus. |
