Dredging can be conducted from the land by using an excavator or submersible dredge pump, or from the water by utilizing a barge or amphibious type of deployment. Many times, it depends on the type of dredging that will be performed, which will generally determine what type of dredging equipment and deployment options that will be available.
Typically, when dredging, the discharged material, or material to be removed, will be pumped to a specified location like a holding pond or tank where it is then properly disposed of. Dredged material is often disposed into self-contained hoppers of the dredgers, in barges, pumping through pipelines, and using natural forces such as waves and currents. Sometimes, however, the material will be easier removed by barge, which can easily be accomplished when using barge-deployed EDDY Pump dredging equipment. This can be done with use of a hydraulic excavator dredge pump attachment.
The excavator dredge attachment is a hydraulic dredge that includes a high-powered EDDY Pump and cutterhead. Most hydraulic dredges have a cutting head to assist with dislodging compacted sediment, breaking it up, and feeding it into the suction of the pump. This dredged sediment, or ‘slurry’, is pumped through a flexible, floating pipeline to a floating barge, or directly to an on-land dewatering facility, where the sediment is allowed to settle out of the water. Barge-based dredging can refer to mounting the dredging equipment right onto the barge itself or pumping the material from land to a floating barge. Dredging directly from the barge allows for greater reach in certain situations that you may not be able to attain while dredging from land. In addition, dredging from a barge allows for the operator to discharge the material straight into the barge for easier transportation. This essentially eliminated the step of moving material to the barge for disposal purposes.
