The Application Fields of Various Dredgers Are Briefly Described
The selection of dredger mainly depends on the nature of dredged material and the meteorological, hydrological and geographical conditions of the construction area.
In the coastal and estuarine areas with big wind and waves and no cover, it is advisable to choose self-propelled rake suction dredger.
The cutter suction dredger with the pipe line is often used in combination with the blow fill. Bucket dredgers with hard soil at the bottom.
When the operation surface is small, for example, at the front of the port, grab dredgers should be used.
Dredger operation, to avoid obstructing the transport ship navigation, pay attention to safe operation and facilities.
In the site to calibrate the exact location of the dredging, lay water level signals, dredging and unloading area signs, often carry out water depth measurement, improve the operation time of the dredger, study and improve dredging methods.
