More About River & Cutter Suction Dredgers

Introduction to Cutter Suction Dredgers .

Cutter suction dredgers are specialized dredging equipment primarily used for soil excavation and dredging at the riverbed or seabed. This type of dredger loosens the soil at the bottom by rotating cutter heads, mixes it with water to form slurry, and then sucks the slurry into the pump body through the suction pipe, finally discharging it to the designated disposal area through the discharge pipe.

Integrated and Efficient Construction Process .

The construction process of cutter suction dredgers integrates dredging, transport, and unloading, significantly enhancing production efficiency. They are mainly suitable for dredging in inland lakes and coastal ports with low waves and low flow rates, particularly effective for excavating sand, sandy loam, and silt. When equipped with toothed cutter heads, cutter suction dredgers can even excavate clay, although with relatively lower efficiency.

Famous Cutter Suction Dredgers Worldwide .

Globally, there are many famous cutter suction dredgers, such as China's Tianjing, Tianhang Bureau 5000kW, and Tiankun (with a cutter power of 6600 kilowatts).

Adaptability and Construction Methods .

In specific construction environments, such as areas with high flow rates or large waves, cutter suction dredgers may require special construction methods. For instance, dredgers equipped with anchor cables and transverse control devices should use anchor cable cross-dredging methods in these situations. Furthermore, when the specifications of the dredged trench vary or when different project timelines are required, construction must also be segmented according to contract specifications.
