        Jet Suction Dredger

        The jet suction dredger is a vessel that integrates the functions of impact, stirring, suction of sediment, and transportation. Its core mechanism is that a high-pressure water pump generates a high-pressure water flow to impact the bottom sediment, making it moist and disintegrate into slurry. Subsequently, through negative pressure, the slurry is sucked into the designated area by the suction pump, thereby enabling the dredging and silt removal operation in shallow water areas.
