Background
As far as the present situation is concerned, the work of dredging and dredging channels is of great importance, which plays an irreplaceable role in the normal operation of the channel and the protection of the surrounding safety. Nowadays, the dredging effect in China is not very good, and due to flooding, a large amount of water is often accumulated at the bottom of a river levee, so that great harm is caused to the levee. If the embankment soil property is loose, the safety belt in the area can be greatly damaged. Meanwhile, some dikes have more sandy soil and have certain sand bases. When the water discharge of the river is too large, the problem of bank breaking even occurs, and once the sedimentation is too large, the problem of bank breaking even occurs. The riverbed is greatly raised, and the flood discharge capacity of the riverway is reduced.
Furthermore, it has been found in practice that river risk zones increase if no effective remediation work is carried out during the river basin remediation process. Because of the problems, the river channel is easy to silt up, so that the normal drainage can not be carried out, the situation that water flow impacts the river bank occurs in the whole process, great economic loss is brought, and great influence is brought to the life of people. Therefore, in the course of river management and maintenance, the construction management of channel dredging must be paid attention to in order to effectively reduce the problem of sediment deposition, further improve the drainage capacity of the river, better ensure the normal operation of the river and protect the surrounding safety.
The dredging of the river channel can effectively remove the pollution of the sediment of the river channel, improve the water environment, enlarge the water passing section and improve the water discharging capability. In recent years, a great number of river channel dredging projects are provided, sludge generated by dredging river channels is one of the difficult points and key points to be solved in river channel dredging projects, and the sludge is not easy to be directly used as foundation soil due to high water content and low strength, so that an environment-friendly sludge treatment device for hydraulic engineering is provided.
