The main purpose of the dredging projects

The main purpose of the dredging project is to excavate the harbor basin, the inbound waterway, etc., to fill the land to build the dock, the port area and the port industrial zone, the coastal city land and recreational land and land reclamation, the shore beach maintenance, the water conservancy and flood control and the reservoir area. Improvement of water environment such as dredging, rivers, lakes and seas, ecological restoration, construction and landfill of various underwater pipelines. The role of dredging projects in human social progress, environmental improvement and economic development is very important.

Use dredging methods to dig shallow sections of deep rivers or bays to improve navigation or flood discharge capacity; an economically viable primary method of landfilling dredged soils in excavation channels or harbor basins into nearby low-lying areas for land reclamation . 

Dredging has traditionally been treated in a manner that is abandoned or dumped in the waters adjacent to the project. The dredging project has created a new way of turning waste into treasure and comprehensively processing it, and then developed it into the use of dredged soil as building materials and materials for building buildings. The dredging project is also extended to excavate the bottom of the river or the bottom of the sea to bury the river or cross-sea pipeline (water pipes, oil pipes, transmission cables, communication cables, etc.); remove the sand and stone for hydraulic engineering with strong underwater displacement capacity. Material foundation and soft ground improvement; blowing sand to protect the beach and so on.

In the past few decades, human beings have increasingly demanded environmental standards. Preventing and reducing the pollution of waters and land by dredging activities has become an important issue that must be considered in dredging projects. Dredging methods are used to excavate underwater contaminated soils and carry out engineering. Processing has also become an important part of dredging projects.
