Description

Technical Field

[0001] The utility model relates to the technical field of river channel desilting, in particular to a river channel desilting device. Background Art

[0002] After years of accumulation, the sand and mud in the river water will continue to settle at the bottom of the river, causing the riverbed to rise continuously. Many rivers have not been dredged and maintained for many years, so their siltation has become more and more serious year by year, resulting in lower flood control and drainage standards in the rivers, especially some tributaries or low-lying rivers, which are more prone to silt accumulation. In order to avoid silt accumulation, they need to be dredged.

[0003] Traditional river channel dredging methods mostly use high-pressure water guns to flush the silt. After the flushing is completed, the mud is pumped out using a mud pump. However, the flushing efficiency of the high-pressure water gun is low. At the same time, the traditional high-pressure water gun needs to be manually held and used, which is labor-intensive. Therefore, the utility model proposes a river channel dredging device to solve the above problems. Utility Model Content
