Apparatus and method for the dredging of sediments from the seabed
A dredging apparatus (1) is described for removing sediments from a bed (F) of an expanse of water (S), comprising: a suction apparatus (5) including a) a submersible pump (18) including: a housing body (17) provided with an inlet mouth (19) and with a discharge opening (20) and an impeller (21) rotatably supported in the body (17) between the inlet mouth (19) and the discharge opening (20) and rotatably driven by a respective driving device (22); and b) a suction head (9) associated to the inlet mouth (19) of the housing body (17) of the pump (18) and provided at the bottom with a suction opening (23) of the sediments; wherein the suction opening (23) of the head (9) has a value of the cross-section area dimensioned to achieve in the working range of the pump (18) 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 (9). The invention also describes a dredging method which may be carried out by means of such an apparatus.
