River channel dredging device and dredging method

Abstract

The invention discloses a river channel dredging device and a dredging method, and belongs to the technical field of river channel dredging. The river channel dredging device comprises a dredging ship body, a salvage assembly arranged at the bottom of the dredging ship body and used for separating sundries and sludge in a river channel sludge layer, a sludge suction assembly arranged on the dredging ship body, communicated with the salvage assembly and used for sucking away the sludge separated from the salvage assembly, a sundry treatment assembly which is arranged on the dredging ship body, communicates with the salvage assembly and is used for treating sundries separated from the river channel sludge layer, and a sludge treatment assembly which is arranged on the dredging ship body, communicates with the sludge suction assembly and is used for treating sludge discharged from the sludge suction assembly. The river channel dredging effect can be better.

Description

technical field [0001] The present application relates to the technical field of river dredging, in particular to a river dredging device and a dredging method. Background technique [0002] At present, river dredging refers to the treatment of rivers, which belongs to water conservancy projects. In the related technology, the dredging of the river mainly uses mechanical equipment such as dredging boats to blow and stir the silt deposited at the bottom of the river into a turbid liquid state and flow away with the river. The silting effect is not good. For this reason, dredging ships are used to desilt in sections, the silt is pumped away, and finally the silt is transported to the silt treatment plant through pipelines for centralized treatment to complete the river dredging work. . [0003] During the dredging operation of the river course in the above-mentioned related technology, the inventor found that there are various sundries such as glass bottles, metal blocks, wo...

Problems solved by technology

In the related technology, the dredging of the river mainly uses mechanical equipment such as dredging boats to blow and stir the silt deposited at the bottom of the river into a turbid liquid state and flow away with the river. The silting effect is not good. For this reason, dredging ships are used to desilt in sections, the silt is pumped away, and finally the silt is transported to the silt treatment plant through pipelines for centralized treatment to complete the river dredging work.

[0003] During the dredging operation of the river course in the above-mentioned related technology, the inventor found that there are various sundries such as glass bottles, metal blocks, wooden blocks or plastic parts in the mud layer at the bottom of the river course, and these sundries will easily block the pipeline, even The dredging equipment will be damaged. If a filter is installed at the front end of the pump suction pipe, the debris in the sludge cannot be cleaned, which will lead to poor dredging effect.
