To provide a dredging carrying device capable of directly carrying recovered deposit sand up to a separated treating plant, by efficiently dredging the deposit sand deposited on the water bottom in the high mixed sand ratio.
This dredging carrying device has a multi-articulated arm device 10 having multi-articulated arms 10c and 10d and movably placed on a pontoon 9, a sand sucking removing device 20 installed on a tip arm of the multi-articulated arms, and a flexible carrying pipe 16 for communicating a delivery port of the sand sucking removing device with the separated treating plant. The sand sucking removing device 20 has a sand removal pump 22, a variably adjusting suction pipe 30 for variably adjusting a distance between a suction port of the deposit sand and a deposit sand surface, and a flexible suction pipe 24 for communicating the suction port of the sand removal pump with the variably adjusting suction pipe. The variably adjusting suction pipe 30 is composed of a hollow suction pipe 32, a movable suction pipe 34, a suction port flange 36 and a linearly moving actuator 38.
