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.

Specification

Applications

1. Waterway and Port Dredging
By breaking up riverbed sediments with a cutter head and transporting them over long distances via mud pumps, it maintains and widens the water depth of rivers and ports to ensure navigation for large vessels. Examples include the deepwater channel regulation of the Yangtze Estuary and the expansion project of Shanghai Yangshan Port Container Terminal.

2. Water Conservancy and Flood Control Projects
It removes silt from rivers and reservoirs to restore flood discharge capacity and reservoir storage. For instance, the "River Dredging" project in the lower Yellow River alleviates the problem of riverbed elevation, while the excavation of the middle and lower Huaihe River enhances flood control standards.

3. Ecological Environment Governance
Using environmentally-friendly cutter suction technology, it removes polluted sediments (such as heavy metal-contaminated and eutrophic silt), complementing water quality improvement and aquatic ecosystem restoration. Typical applications include ecological dredging in cyanobacteria-polluted areas of lakes like Taihu and Dianchi.

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.
