Cutter suction dredger with a pumping depth of 15 meters can be customized

product description

A cutter suction dredger is a large, efficient, and continuously operating engineering vessel that integrates excavation,transportation, and discharge. It is one of the most commonly used and important ship types in modern dredging projects. It is particularly suitable for channel dredging, port construction and maintenance, land reclamation, water conservancy projects, environmental dredging, and other fields.

Core working principle:

The core working principle of a cutter suction dredger can be summarized as "loosening, suction, pumping, and discharge" in four steps:

Loosening (cutting): A powerful cutter head is installed at the lower part of the bow. This cutter head is usually driven by a motor or hydraulic drive to rotate at high speed, and the teeth (or blades) cut, loosen, and crush the mud, clay, gravel, and even soft rock on the bottom of the water.

Suction: A large suction pipe inlet is installed near the cutter head. The loosened mud-water mixture (called mud) is sucked into the suction pipe under the strong negative pressure (suction) generated by the mud pump (usually located in the hull).

Pumping: The sucked mud is transported to the mud pump on the ship through the suction pipe. After the mud pump is pressurized, the mud is transported to the predetermined discharge location through the mud discharge pipeline (which can be a floating pipe floating on the water surface or a submerged pipe buried in the water).

Discharge: The mud is finally discharged to the designated area

product parameters

Advantages:

Continuous and efficient operation: Excavation, suction, transportation and discharge are carried out continuously without intermediate transfer links, and the production efficiency is extremely high.

Strong excavation capacity: It can adapt to a wide range of soil types from silt to weathered rock (the specific capacity depends on the type of auger and the power of the ship).

High excavation accuracy: Through precise positioning and control systems (such as DTPS - dredging trajectory positioning system), high-precision cross-section excavation can be achieved, and the flatness of the channel and foundation trench can be well controlled.

Long transportation distance: Through relay pump stations, mud can be transported to the discharge area more than  ten or even dozens of kilometers away.

Environmental protection (relative): Small disturbance (compared to grab buckets and chain buckets), the excavation range can be accurately controlled, and the mud can be transported in a closed manner to reduce secondary pollution to  the water environment. It is particularly suitable for environmentally friendly dredging.

High integration: A single ship completes the entire dredging process.
