A suction sand pumping vessel is an engineering vessel that utilizes high-pressure water jets to create negative pressure for extracting underwater sand, silt, or gravel. This hydraulic dredging method is particularly effective for loose sand media.

"Jeting" + "Suction"

Jeting: Loosens mud and sand with high-pressure water jets:

• Equipped with a high-powered water pump that pressurizes water from the operating area
• Delivers pressurized water through specialized nozzles to target sand layers
• Disperses sand particles and liquefies compacted layers for easier pumping

Suction: Removes slurry with centrifugal pump:

• Sand suction head located near high-pressure nozzle
• Centrifugal sand pump generates powerful vacuum suction
• Slurry is transported via pipelines to designated locations

Dredging Engineering:

• Waterway, port, and canal excavation and maintenance
• River channel dredging for flood prevention and navigation improvement
• Reservoir and lake dredging for capacity restoration
• Water conservancy project foundation excavation

Land Reclamation:

• Extracting sand/gravel for artificial islands and land expansion

Mining:

• River and sea sand extraction for building materials

Environmental Projects:

• Polluted sediment removal
• Wetland restoration
• Environmental dredging with eco-friendly suction boats
• Submarine pipeline/cable trench preparation

Blowing and Filling:

• Transferring dredged material to designated areas for land formation
