Description

Technical Field

[0001] This invention belongs to the field of dredging engineering technology, and in particular relates to a containerized combined cutter suction dredger that is easy to transport. Background Technology

[0002] A cutter suction dredger uses a rotating cutter head to loosen soil from the riverbed or seabed, mix it with cement to form slurry, which is then sucked into the pump body through a suction pipe and transported to the discharge area through a discharge pipe. During operation, the dredging, conveying, and unloading of slurry are all integrated and completed by the dredger itself, resulting in high production efficiency.

[0003] In recent years, with the continuous development of environmental protection and greening projects, the amount of dredging projects in inland rivers and lakes has been increasing. Traditional cutter suction dredgers used in inland river dredging have problems such as inconvenience in transportation and excessively large bridge dimensions due to structural limitations. Summary of the Invention

All equipment on the vessel is powered by shore power and is primarily used for water conservancy projects in inland rivers and lakes. During dredging, the dredger is positioned using steel piles and moved by a lateral movement system. This invention allows for rapid and flexible assembly; the standardized modular design facilitates vehicle transport; and the underwater pump and cutter motor are located within the bridge frame, ensuring the bridge frame's strength while reducing its size, thus improving installation, transportation, and overall vessel construction efficiency.
