Dredgers are responsible for clearing silt from waterways and rivers so that other ships can pass smoothly.It is also a powerful tool for sand blowing and reclamation.There are cutter suction dredgers, trailing suction dredgers and other types.The smooth flow of the river depends entirely on dredgers.
The task of the dredger is to carry out underwater earth and stone construction, specifically: digging, widening and cleaning existing channels and ports; digging new channels, ports and canals; dredging docks, docks, locks and other water The foundation trenches of industrial buildings and the excavated sediment are thrown into the deep sea or filled in land depressions to create fields.It is a powerful tool for blowing sand and reclamation.
The cutter suction dredger is a type of ship widely used in dredging projects. It uses the front end of the suction pipe to install a rotating cutter device around the suction pipe to cut and stir the river bottom sediment, and then suction the mud. The pipe transports the winched sediment material to the sediment material storage yard with the help of powerful pump force. Its dredging, transporting, unloading and other working processes can be completed continuously at one time. It is a high-efficiency and cost-effective method. The lower dredger is a good underwater excavation machine.The total length refers to the sum of the length of the hull plus the extended length of the winch and suction frame.The dredging pump is directly driven by the main engine, and the reamer head is driven by a motor or hydraulic mechanism. Assume that the dredging efficiency is 30% of the discharge weight. According to Archimedes' law, the theoretical suction depth of a single-stage dredging pump is 0M, but in fact it does no
