Title:
DREDGING SYSTEM
Document Type and Number:
Japanese Patent JP2016023426
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dredging system having a water feeding pump hung from a barge-type platform floating on a reservoir water surface, capable of vacuuming bottom mud with the water feeding pump for dredging and efficiently separating and recovering the vacuumed bottom mud.SOLUTION: A dredging system 100 of the present invention uses an inorganic neutral coagulant for coagulating bottom mud and transports bottom mud slurry (bottom mud and supernatant water) from a reservoir to a belt press part 80 by pumping a water feeding pump 20 and using a natural water flow. As such, condensed bottom mud may be transported to the belt press part 80 with its high concentration retained, without re-dispersing the coagulated and condensed bottom mud. The dredging system 100 of the present invention dehydrates the condensed bottom mud continuously with the belt press part 80, enabling separation and recovery of the bottom mud at an extremely high efficiency.SELECTED DRAWING: Figure 1
