Description

Reamer special for cutter suction dredger of engineering ship

Technical Field

The invention belongs to the technical field of ship construction, and particularly relates to a reamer special for a cutter suction dredger of an engineering ship.

Background

The dredger is used for dredging water channels and river silt so that other ships can smoothly pass through the dredger. The dredging of the river channel is totally expected to the dredger, and the dredger is also a sharp tool for blowing sand and filling the sea. Common dredger mainly comprises a cutter suction dredger, a trailing suction dredger and the like. The task of the dredger is to carry out construction of underwater earthwork, specifically: digging, widening and cleaning the existing channel and port; excavating new channels, ports and canals; dredging the foundation trench of wharfs, docks, ship locks and other hydraulic buildings, throwing excavated sediment into deep sea or filling land depression for field construction and the like. The cutter suction dredger is a ship widely applied in dredging beach engineering, and is characterized by that it utilizes the front end of suction pipe to install a rotary cutter device around the suction pipe to cut and stir the river bottom silt, then utilizes the suction pipe to convey the twisted silt material into silt material pile-up field by means of strong pumping force. The cutter suction dredger has wide application, can be operated in rivers, lakes and seas, and is used for dredging, dredging channels and dredger filling to build land.
