technical field

The present application relates to the technical field of canal dredging, in particular to a dredging device for water canals in water conservancy projects.

Background technique

Regardless of whether the canal is a concrete canal or a canal without concrete on the surface, silt will be deposited at the bottom of the canal body after a certain number of years of use, and the deposited silt affects both water quality and water delivery efficiency, so the silt in the canal is usually cleaned regularly . Among them, when dredging medium and large concrete canals, the common dredging method is that the staff use high-pressure water pipes to flush the sludge, wash away the sludge and dissolve it in the water, and then pump the sludge after flushing to a designated area. location.

In view of the related technologies mentioned above, the inventor thinks that there is the following defect: before the sludge is sucked, the sludge needs to be washed, especially in the dry season and when the water in the canal is low, the sludge at this time is relatively hard, and the required The flushing time is longer, which in turn leads to lower overall dredging efficiency.
