The Dredging Depth of Cutter Suction Dredger

Cutter suction dredgers are responsible for dredging the silt in waterways and rivers for the passage of other ships. During operation, the operator needs to dig, widen and clean up the existing port, so how to determine its dredging depth?

In case of general engineering dredging, it depends on what cross-sectional area the dredger needs to dig, and there must be in-depth data; If it is to improve water quality, the dredging depth should be considered from the perspective of environmental protection and ecology. However, in any case, some preliminary work should be done, such as collecting columnar sediments, analyzing the content of layered pollutants, then analyzing the content of layered heavy metals, and making the risk index of heavy metal ecological hazards of dredgers.

By drawing these contents and indicators into vertical curves, the cutter suction dredger can roughly determine the dredging depth in combination with the background value of the area. Of course, we should also consider the release of some sediments.
