Technical Field
The invention belongs to the technical field of dredging construction, and particularly relates to a novel environment-friendly dredging sand barge.
Background
In 25 months 3 in 2020, fifteen committees of the state jointly issue guidance opinions about promoting the healthy and orderly development of the sandstone industry, and the guidance opinions require the comprehensive reutilization of the channel dredging sand to be increased, and the comprehensive utilization and trial experience of popularization is summarized in time. At present, a dredging sand loading and barge mode adopts a deep-cabin barge self-overflow mode, and slurry is generally conveyed to a loading and barge platform by a trailing suction ship or a cutter suction ship through a floating pipe, and then the loading and barge platform conveys the slurry to the deep-cabin barge. The deep bay barge is a ship for conveying dredged sand back and forth, sails to a wharf after being fully loaded, and brings the dredged sand to the shore. The concentration of slurry received by the existing deep hold barge is low, about 30 percent, the hold capacity is improved by overflowing and draining water from the upper side of a barge hatch when the deep hold barge is held, fine-particle silt is difficult to deposit due to turbulent motion of the slurry in the barge hatch, the fine-particle silt is discharged along with overflow liquid, a large amount of overflow causes adverse effects on the environment, the turbidity of a construction water area can be greatly improved by the overflowed slurry, the ecological system is adversely affected, a large amount of time is occupied by the overflowing and draining water, and the utilization rate of the barge is reduced. The dredged sand loaded is drained via overflow, but the water content is still high, resulting in a decrease in the effective loading of the barge.
