Mechanical dredgers use powerful scoops, buckets, or grabs to remove sediment from the dam or reservoir floor. Operating from a barge or floating platform, they collect dense or coarse materials like gravel, rocks, and larger debris.
Once scooped, the material is offloaded onto waiting vessels or onto the shoreline. Mechanical dredgers are ideal for projects that demand robust handling of tough materials and straightforward disposal processes.
Amphibious Dredgers
Amphibious dredgers are uniquely designed to navigate shallow or swampy areas where traditional dredgers struggle to operate. Equipped with specialized track systems or pontoons, they can travel over both land and water, ensuring comprehensive cleaning of areas prone to sediment buildup.
This mobility allows them to tackle complex topographies around dams, minimizing the need for additional site preparation. By accessing hard-to-reach spots, amphibious dredgers help maintain proper water flow, prevent excessive sedimentation, and preserve overall dam functionality.
Hydraulic Dredgers
Hydraulic dredgers rely on suction and pipeline systems to remove sediment and water as a slurry. This category includes cutter suction dredgers and trailing suction hopper dredgers, both well-suited for handling large volumes of softer materials such as silt, clay, and sand.
By pulling materials directly through a pipeline, these dredgers minimize re-suspension of sediment and reduce environmental impact. Their efficiency in deep or confined spaces makes them a reliable choice for dam cleaning and maintenance.
