Hydraulic dredges create slurries, combinations of solids and water, pump the slurries to the surface of lagoons, ponds, lakes, waterways, and canals, and then pump the slurries through floating and land based pipe to disposal sites. The hydraulic dredging process can be continuous, as contrasted to intermittent in the case of so-called clamshell dredges. Basic components of hydraulic dredges include a cutterhead, pump, floatation system or platform, engine or motor, control system, and the discharge system. Cutterheads dig up settled solids in the waterway to be dredged and create slurries. A powerful centrifugal pump mounted directly behind the cutterhead draws the slurry into a discharge piping system, pushes the slurry to the surface, and then to the discharge site, often thousands of feet away from the dredging site - hydraulic dredging.
Dredges that are positioned with spuds long, powerful spikes driven into the bottom of the waterway and use hydraulic rams to apply forward force to the cutterhead. Hydraulic dredges are defined also by the depths to which they can dredge, the volume of water and/or solid material they move, the height to which they can discharge the slurry, the power of the auger or cutterhead, the hardness and abrasiveness of the slurry, the size of solids the dredge pump can pass, dredging speed, width of dredging cut, the cutting power torque of the auger, and the cost of the dredge - mechanical dredging.
We provide one-stop services including project engineering schemes, research and development design, customized construction, installation and commissioning, and operation management. Selecting the best dredge solution for any application requires careful analysis by experienced, well-trained people in collaboration with the customer’s staff. Frequently, such an analysis requires the efforts of engineers with the skills and experience to sort out the many variables.
