Product Description

Cutter Suction dredger

The cutter suction dredger is the use of rotating reamer to loosen the soil at the bottom of the river or the seabed, mixing water and sediment into a mud-water mixture, which is sucked into the pump body through the suction pipe and sent to the far end of the mud discharge area through the mud discharge pipe.  During the construction of cutter suction dredger, dredging, mud transport and mud unloading are integrated, complete by themselves, and have high production efficiency.  It is suitable for dredging inland lakes and coastal ports with small wind waves and low flow rate.  It is more suitable for excavation sand, sandy loam, silt and other soil, and can also dig clay after using toothed reamer.  The cutter head and other parts of the cutter suction dredger can be divided into hydraulic and mechanical power, of which the hydraulic type has a wider range of application and is more convenient to operate.

Applications

1.Waterway Dredging and Maintenance:
Dredging silt from rivers, lakes, and coastal waterways to maintain navigable water depth and ensure safe navigation for ships.

2.Port and Wharf Construction:
Excavating port basins and wharf foundation trenches during new port construction to create conditions for ship berthing and cargo loading/unloading.
Deepening and widening water areas during port expansion or renovation to accommodate large vessels.

3.Water Conservancy Project Construction:
Excavating foundation pits or clearing reservoir bottom silt during the construction of reservoirs and dams.
Regulating rivers and lakes to expand flood discharge sections and improve flood control capabilities.

4.Hydraulic Filling and Land Reclamation:
Transporting dredged slurry through pipelines to designated areas (such as shoals and tidal flats) for reclamation or land consolidation.
Applied in urban construction (e.g., airports, industrial zones, residential development) and agricultural land expansion.

5.Mineral Resource Mining:
Mining sand, iron ore, rare earths, and other resources in shallow seas or inland waters by suctioning sedimentary minerals from the seabed or riverbed for onshore processing.

6.Environmental Dredging and Ecological Restoration:
Removing polluted sediment (e.g., heavy metal-contaminated or eutrophic silt) from lake and river bottoms to improve water quality.
Restoring wetland and estuarine ecosystems in ecological projects to protect biological habitats.

Advantages

1.Efficient construction: It realizes the integration of dredging, mud transport and mud unloading, can work continuously for 24 hours, has a low failure rate and only needs 1-3 people to work, which greatly improves the construction efficiency.

2.Strong adaptability: It can carry out dredging work in different waters, and has good excavation and transportation capacity for various soil qualities.

3.Controllable accuracy: It can accurately adjust the digging depth, width and working area through the control system, Beidou positioning or GPS to meet the specific requirements of different working conditions.

4.Convenient transportation: Its structure adopts split assembly design, which can be assembled by car transport to the internal construction waters that are not navigable, and the modular assembly method significantly reduces the transportation cost, greatly reduces the assembly time, and also reduces the use of large machinery.
