What are the application scopes of cutter suction dredgers?
The cutter suction dredger has a wide range of adaptability and is suitable for construction in inland rivers, lakes, and coastal port channels and harbor basin waters. It is most suitable to excavate sandy loam and silt. The new type of large cutter is equipped with heavy-duty cutters and anti-wave devices, and can be applied to the excavation of hard substrates such as weathered rock and offshore construction.
However, in some cases, cutter suction dredgers are not suitable for use, for example:
Ordinary cutter suction vessels are not applicable when the wind and waves are strong.
(2) Not applicable in areas with excessive flow velocity.
(3) It is difficult to give way on busy port waterways and narrow and long waterways.
(4) Sludge discharge pipes must not cross waterways or port areas.
(5) It is not suitable when the dredging depth is greater than the maximum dredging depth of the dredger or less than the water depth for the dredger's construction.
