10-inch jet suction dredger with 900m3/h capacity for river dredging

Product description

A jet-suction dredger is an engineering vessel that uses high-speed water flow (jet) to impact and destroy underwater mud and

sand, and relies on vacuum suction (suction) to remove the mud-water mixture. It is an important type of hydraulic dredger,

especially suitable for dredging soft silt, fine sand and other non-cohesive or weakly cohesive bottom materials.

product parameters

The above technical parameters are for reference only,specific device configuration depends on the conditions of each

project,customer and technical requirements.

Working Principle

Working Principle
“Jet” - High-pressure water jet impact:

The ship is equipped with a high-power high-pressure water pump to absorb water from the outside of the ship (usually the clearer water

in the upper layer of the operating water area) or the circulating water tank inside the ship.
The high-pressure water is transported through a pipeline to a nozzle (nozzle) installed near the mud suction port (suction head).
The nozzle concentrates the high-pressure water to eject a high-speed, high-energy water column (jet) directly impacting the mud at the

bottom of the river, the seabed or the bottom of the reservoir.
The kinetic energy of the high-speed jet effectively cuts, disperses, and liquefies (mixes the mud with water to form mud) the mud layer

in the target area.

“Suction” - Vacuum suction:

A powerful mud pump (centrifugal pump) is connected near the mud suction port (usually just above or around the jet nozzle).
When the mud pump is working, a strong negative pressure (vacuum) is generated at its suction end.
This negative pressure sucks the mud (a mixture of water and mud) formed by the jet impact liquefaction into the pipeline through the

mud suction port.
The sucked mud is pressurized by the mud pump through the pipeline and discharged.

Application

Main application areas
Channel maintenance dredging: Remove the naturally deposited silt in ports, waterways, and canals to ensure the navigable water depth.

Inland river and lake desilting: Control river siltation, desilt reservoirs, and improve water quality.

Land reclamation: Transport the dredged silt to the designated area through the mud pipe for land reclamation or low-lying filling (suitable

soil is required).

Foundation engineering excavation: Excavate foundation pits for underwater projects such as docks and bridge foundations (soft soil is

required).

Environmental desilting: Remove contaminated bottom mud (anti-diffusion measures and subsequent treatment are required).
