These dredges feature specialized rotating mechanical cutterheads that suck dredged material through an intake pipe at one end and flush it out a discharge pipeline directly into the disposal site.īecause they pump directly to the placement site, cutter suction dredges are efficient and highly cost-effective. Cutter Suction DredgesĪ cutter suction dredge is a specific type of hydraulic dredge. These instruments are rugged and durable to withstand the harsh, sometimes salty marine environment where dredges operate. At GeoForm International, we make two top-of-the-line hydraulic dredges - the Dino6 and the Dino8. Most modern dredges have computer-assisted onboard instruments. A hydraulic dredge that takes in too much water will be inefficient, and a dredge that takes in too little water will eventually bog down under the volume of incoming sediment, mud or rock. The dredge carefully controls the proportions of water and other material it takes in. Then, atmospheric pressure and the water’s weight combine to force the water and material through a pipe and into a pump. It contains a centrifugal pump that creates a partial vacuum. Hydraulic dredges are cost-effective, mobile, dependable, highly versatile and suitable for challenging conditions.Ī hydraulic dredge works by sucking in water and material from the bottom of the waterway. Hydraulic dredging is the superior solution in many dredging scenarios.

If you’re like many people, though, you may not be sure where to start with dredging. It can also help industrial operations like power plants, water treatment facilities, and mining sites increase their productivity. It can improve fish habitats, correct erosion, deepen ponds and make waterways more navigable. Doing so removes silt and other undesirable materials from the bottoms of lakes, lagoons, harbors, rivers, and other waterways, improving their functionality and aesthetic appeal. If you deal with a waterway in your business, you may need to dredge it on occasion. Jump To: Hydraulic Dredging | Mechanical Dredging | Sizing Your Dredge Appropriately
