Top Mechanical & Hydraulic Dredging

 

Hydraulic dredges offer a non-disruptive solution for desludging, enabling operations to continue uninterrupted without requiring a complete shutdown. Their enclosed pipeline systems prevent odors and reduce the potential for spillage or environmental contamination. Ports, harbors, rivers, and inland waterways require consistent dredging to maintain navigable depths. Hydraulic dredging is preferred for removing soft sediments, such as silt and sand, efficiently and with minimal disruption to marine traffic. Continuous operations with real-time monitoring enable the management of depth control while staying within environmental thresholds - mechanical dredging.

For dredging, dredgers are used to remove the deposited sediments from an inlet creek, waterway or ocean floor. Sedimentation is natural, and sometimes excessive silt, sand, stones, and other debris accumulate on the bottom of canals, rivers, lakes, etc, reducing the waterways’ depths. Water depth influences the type and configuration of the hydraulic dredging equipment.  Basic components of hydraulic dredges include a cutterhead (auger), pump, floatation system or platform, engine or motor, operational controls, and discharge. Auger dredges mix the sediment with water with their cutterhead, and pump the slurries to the surface of lagoons, ponds, lakes, waterways, and canals. The material is then pumped through floating and land-based pipe to a disposal/spoil site - mechanical dredge.

Mechanical dredging, on the other hand, is better suited for hard or compacted materials like gravel, clay, and rock. The physical digging action of a backhoe or clamshell bucket makes it easier to handle tough materials that would clog or resist suction systems. This is widely considered the most effective method of dredging when the environment and the ecosystem of the dredging site is of major concern. It is preferred because it prevents most of the contaminated sediments from being dispersed or released into the nearby water source. Bucket dredging is one of the original methods of dredging, where a stationary barge equipped with a boom of large, consecutive buckets rotates, scooping material from the dredge site.
