500m3/h flow rate jet suction dredger for small rivers and lakes

product description

A jet-suction dredger is an engineering vessel that uses high-pressure water jets to loosen the silt and then uses a centrifugal pump to suck the silt under negative pressure to complete the dredging operation. It is an important branch of mechanical dredgers.

product parameters

The above technical parameters are for reference only,specific device configuration depends on the conditions of each project,customer and technical requirements.

Typical operation scenarios
Inland waterway maintenance

Case: Dredging in the middle reaches of the Yangtze River (annual silt removal volume 2 million m³, 65% of which is

from suction jets)

Parameters: working water depth 4-8m, mud concentration 35-45%

Dry filling and land reclamation project

Case: Shenzhen Qianhai reclamation (suction jets and suction dredgers complete 30% of the project)

Innovation: GPS automatic navigation forms a sand extraction grid

Special operations

Shipwreck salvage: suction covering silt

Undersea mining: extracting metal sand with grading screens
