Customized Jet Suction Dredger with Long Discharge Distance Pumping Sand River
product description
A Jet Suction Dredger (JSD) is a specialized type of dredging vessel designed for efficient and cost-effective removal
of loose, non-cohesive materials such as sand, silt, and gravel from underwater environments. Unlike other dredgers
that rely on mechanical cutting or excavation, Jet Suction Dredgers use high-pressure water jets to fluidize the seabed
material, making it easier to suction and transport. This method is particularly effective in environments where the
material is soft and easily displaced.

1. Working Principle
Suction system: The hull is equipped with a high-power centrifugal pump to form a vacuum in the pipeline,
and the mixture of silt and water (mud) is sucked in through the suction head or auger.
Auger device (key component): The rotating auger cuts and stirs the sediment on the riverbed or seabed to
suspend it for easy suction.
Transportation system: The mud is pumped to the mud discharge area (such as the reclamation area or mud
transport ship) through the pipeline, and some designs can be discharged directly to the shore.
2. Main features
Efficient and continuous operation: The auger and suction are synchronized, suitable for large-scale dredging
projects (such as port expansion and waterway maintenance).
Strong adaptability: It can handle different bottom materials such as silt, sand, and clay, and the working
conditions can be matched by changing the auger type (such as tooth type, environmentally friendly type).
Precise control: Modern models are equipped with GPS and depth sensors to achieve high-precision terrain
shaping.
Environmental design: Some use low-disturbance auger or enclosure to reduce the spread of suspended
matter and protect aquatic ecology.
