Description

TECHNICAL FIELD

[0001] The present application relates to a sliding dredging machine pump device, belonging to the technical field of water conservancy projects. BACKGROUND

[0002] Sediment deposition is mainly affected by natural and human factors. The former is caused by rain weather, which causes soil erosion and makes a large amount of soil flow into the river, resulting in sediment deposition at the bottom of the river channel over the years. The latter is due to the organic matter generated in daily life, which is randomly discharged into the river. After a part of the river is cleaned, the residual part is deposited in the channel with a larger proportion. After a long-term effect, the sediment is formed in the channel, and if it is not cleaned in time, it will cause the growth of algae and further cause water pollution, triggering a series of ecological environmental problems.
