Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of environmental governance, and particularly relates to a river channel dredging device and a dredging method thereof. BACKGROUND

[0002] River channel silting has gradually affected the normal functioning of flood control, drainage, irrigation, water supply, navigation and other functions. In order to restore the normal function of the river channel, make the river channel through governance to be deep, wide and clear, and at the same time, improve the production conditions and living environment of the masses, achieve the goal of "water clear, river smooth, green bank, beautiful scene", and promote the rapid and sustainable development of economy and society, it is very important to carry out river channel dredging and dredging engineering. For small and medium-sized river channels with small flow and without flood control, drainage and navigation functions, there are fewer special ships and equipment that can enter the river channel for dredging. Therefore, the river channel is usually drained and the silt is removed by dry excavation, which has a complex processing procedure and high construction cost. At present, some dredging equipment has certain requirements for water depth, and cannot be used in shallow water channels.

[0003] In the prior art, a patent with publication number CN 216552147 U discloses a river channel dredging device for water conservancy construction, which comprises a supporting mechanism, a storage mechanism and a dredging mechanism. The supporting mechanism comprises a base for supporting and moving the dredging device. The storage mechanism is arranged above the base and comprises a storage tank for storing and processing the silt cleaned by the dredging device. The dredging mechanism is arranged on one side of the storage tank and comprises a power assembly and a crushing assembly arranged at one end of the power assembly. The power assembly is used to provide the power required by the dredging device for sucking silt, and the crushing assembly is used to crush large silt to prevent the dredging device from being blocked. The dredging device can crush large silt or soil blocks at the position of the dredging head to prevent the dredging device from being blocked and reduce the dredging efficiency. Moreover, the dredged silt can be filtered, and then the filtered water is injected back into the river channel to reduce water waste. However, the dredging device can only store and process the silt cleaned by the dredging device, and cannot dredge the river channel silt.
