PROBLEM TO BE SOLVED: To provide a dredging system capable of dredging bottom sand of a reservoir that contains a large amount of sand, without draining water in the reservoir.SOLUTION: A dredging system 100 sends air to a water pump 20 and force-feeds dredging water mixed with the air. The configuration causes the dredging water to flow down inside a feed hose 12 as a turbulent flow, and prevents accumulation of bottom sand inside the feed hose 12. Thus, the dredging system 100 is capable of smoothly force-feeding the bottom sand containing a large amount of sand components, allowing smooth and efficient dredging of the bottom sand containing the sand components.SELECTED DRAWING: Figure 1 |
