Auger Suction Dredge: An auger-suction dredge drills holes through the bed to loosen and suck the debris.Here is the equipment commonly used for sediment removal. It involves the removal of loose or hard, compacted debris by cutter heads. Suction-Mechanical Dredging: Combines suction and mechanical dredging.Mechanical Dredging: It’s removing loose, hard, or compacted materials by dipper, clamshell, or ladder dredges, both for maintenance and new projects.Suction Dredging: Involves removing loose materials in water by hoppers, dustpans, and hydraulic pipeline plain suction, usually for maintenance projects.Here are the most common types of dredging for sediment removal. The dredge will then transport away the sediment and debris for final processing.The submersible pump will remove the sediment from the waterway’s bottom.A rotating cutter-bar will then use its teeth to loosen the debris or sediments. The operator lowers the dredge boom to the bottom or side of a body of water.Here are the steps of the dredging process. It creates a vacuum to help suck up and pump out dredging material from the bottom of a water body. Dredging Processĭredging involves the use of specialized equipment known as dredges to remove unwanted sediments. Now, let’s look at how the dredging process works and the various types of dredging. The underwater excavation process is an essential part of waterway construction projects, such as docks, bridges, and underwater tunnels. This helps to deepen waterways to allow easy passage of ships. The good news is that one can remove the excess sediments from the bottom or banks of water bodies through dredging. Excess build-up of sediments can reduce the depth of water and cause water contamination. Simply put, sedimentation is the accumulation of sand, silt, and other debris at the bottom of a water body. What is dredging in construction? If you’ve heard about sedimentation in rivers, lakes, and canals, you will quickly understand the dredging process.
