The engineering of excavating and treating the bottom mud, sand and stone in the waterway or port waters according to the specified scope and depth. Dredging is one of the main means of developing, improving and maintaining waterways and port waters.
With the vigorous development of the dredging market and the rapid progress of science and technology, in order to meet the construction requirements of different projects, various shipping companies have developed different types of dredging ships and put them into use. The more common dredging ships in engineering can be divided into mechanical and There are two types of hydraulics.Mechanical dredgers mainly use excavators for underwater excavation, and use the machines themselves for vertical lifting to achieve the purpose of dredging, mainly including grab dredgers, bucket dredgers and chain bucket dredgers;Hydraulic dredgers use mechanical rotation to cut the underwater soil layer, mix the sediment with water to form a certain concentration of mud, and transport it ashore through the mud pipeline, including suction dredgers, cutter suction dredgers and rakes Suction dredger, etc.
