Dredgers are responsible for clearing silt from waterways and rivers to allow other vessels to pass smoothly. Our company manufactures dredgers, gold dredgers, sand dredgers, iron sand extraction machinery, and other dredging equipment. Do you know how they work? Let's take a dredger as an example and explain its specific operation process.
Some dredgers do not have their own propulsion system; they are moved to each new working position by tugboats. The mud and sand excavated from the seabed are loaded into waiting barges and towed away. Self-propelled dredgers operate in waterways used by larger vessels, using large hoses (dredging pipes) to suck up silt. The dredger stores the mud and sand in its hold, and after it's full, it sails to the open sea to dump the material. Side-boom dredgers are effective tools for clearing narrow waterways. They move steadily and slowly, traveling about 3700 meters per hour, excavating a waterway approximately 35 meters wide at the bottom of the lake. The pump sucks up the mud and sand and sprays it back into the water far from the waterway along a long boom. Large ships with deep drafts particularly rely on this type of dredger. The task of a dredger is to carry out underwater earthwork construction, specifically: deepening, widening, and clearing existing waterways and ports; excavating new waterways, ports, and canals; dredging the foundations of docks, shipyards, locks, and other hydraulic structures; and dumping the excavated mud and sand into the deep sea or using it to reclaim land in low-lying areas. The working capacity of a dredger is expressed in cubic meters of soil it can excavate per hour.
