To provide a technology of enabling dredging operations to be performed in a non-powered manner with a high degree of efficiency without use of large-scale equipment.
This dredging conveyance system comprises: a dredging section 10 which performs dredging by utilizing a difference between a water level of a dam lake and that of the inside of a water receiving tank 34; a conveyance section 20 which conveys dredged sediment water to a dam body D through a carrier pipe 24; a dam-body crossing section 30 which transfers the sediment water into the water receiving tank 34 by exceeding the difference of elevation between the water level of a reservoir and the top section of the dam body D through the use of atmospheric pressure (natural energy) by means of the water receiving tank 34 installed outside the dam body D; a downstream conveyance section 40 which discharges the sediment water to a low place from the water receiving tank 34; and a downstream power-generation section 60 which generates electric power by utilizing the energy of the motion of the sediment water in a sediment water discharge step.
