The main objectives of the dredging project are: excavation of port basins, access channels, etc., filling land to build docks, port areas and port industrial areas, coastal urban land and recreational land, shore maintenance, water conservancy flood control and reservoir areas Dredging, improvement of water environment such as rivers, lakes and seas, ecological restoration and construction and landfill of various types of underwater pipeline trenches. Dredging projects have a very important role in the progress of human society, environmental improvement and economic development.
Using dredging methods, dig deep rivers or shallow sections of bays to improve the navigation or flood discharge capacity of the channel; dredging the excavated channel or harbor basin to a low-lying land nearby for a major economically feasible method . Dredged soil has traditionally been disposed of by dumping or dumping in the waters near the project. The dredging project created a new way of turning waste into treasure and comprehensive utilization for treatment, and then developed into the use of dredged soil as building materials and materials for renovating buildings. Dredging works have also been extended to excavation of river bottoms or subsea slots to bury river crossing or sea crossing pipelines (water pipes, oil pipes, transmission cables, communication cables, etc.); excavation of underwater soft soil to replace sand and stone hydraulic structures with strong bearing capacity Material foundation; sand blowing to maintain the beach and so on.
Over the past 20 years, humans have been increasingly demanding environmental standards. Preventing and reducing the pollution of water and land areas by dredging activities has become an important issue that must be considered in dredging projects. Using dredging methods to excavate underwater contaminated soil and carry out engineering Treatment has also become an important part of the dredging project.
Dredging project: It can be seen that the dredging project is very important to the development of the national economy, especially the water transportation, water conservancy and flood control, industrial development and urban construction, and the offshore energy industry. It is indispensable.
