The drag suction dredger is a large self-propelled and bin-loading dredger equipped with a drag head excavator tool and a hydraulic mud suction device. When the dredger is used for dredging, the rake suction pipe is put down to the river bottom, mud is absorbed from the river bottom through the rake head and the mud suction pipe by utilizing the vacuum action of the mud pump and enters a mud bin of the dredger, after the mud bin is full, the rake is lifted to sail to a mud throwing area, a mud door is opened, mud is discharged, or the dug mud is directly discharged out of the dredger. Some dredger can also automatically suck out the soil unloaded from the mud bin for hydraulic filling. The self-propelled. The method is suitable for excavation and maintenance of a long and narrow coastal harbor channel without shield so as to achieve the highest efficiency in silt excavation.
Generally, a barge is arranged on a ship board of the trailing suction dredger, and the barge is used for loading slurry onto the slurry barge after the slurry barge stops.
