Hydraulic and River Engineering
River Dredging: Removing sediment and silt from the bottom of rivers, lakes, and reservoirs to ensure navigability and flood safety, such as the Pearl River Delta Water Resource Allocation Project.
Land Reclamation / Sea Filling: Transporting sand from the seabed or tidal flats over long distances through pipelines for land reclamation.
Reservoir Dredging: Regularly clearing sediment in front of hydroelectric dams to maintain storage capacity and power generation efficiency.
Mining and Metallurgy Industry
Tailings Transport: Transporting post-processing tailings (with concentrations up to 50%-60%) to tailings ponds or backfilling mined-out areas.
Slag Handling: Transporting high-temperature solid wastes such as blast furnace slag and furnace slag from steel mills.
Energy and Power Sector
Fly Ash Transport: Power plants pump combustion-generated fly ash to storage or comprehensive utilization facilities.
Coal Sediment Pond Cleaning: Removing coal slurry and residue from the bottom of power plant sedimentation ponds.
Municipal and Environmental Engineering
Urban Dredging: Cleaning sediment and sludge in stormwater pumping stations, municipal pipelines, and oxidation ditches in wastewater treatment plants.
Fish Pond / Sedimentation Pond Cleaning: Used for removing bottom sludge from aquaculture or industrial sedimentation ponds.
Special Material Extraction
Gold / Iron Sand Mining: Extracting valuable minerals like gold sand and iron sand from riverbeds or beaches.
Corundum / Quartz Sand Recovery: Recovering waste slurry in stone processing plants or sand and gravel yards.
Petroleum and Drilling Operations
Drilling Sand Discharge: Timely removal of bottom sand in oil drilling to solve the problem of sand discharge in wells.
