いる。2. Description of the Related Art In recent years, a phenomenon called siltation in which sediment flows in and accumulates due to tidal currents in shipping routes and anchorages has become a problem in ports in the bottom sea area where particles such as mud and silt are fine.
【０００３】このシルテーション現象により航路、泊地
の水深が年々浅くなり船舶の航行にも支障をきたしかね
ない状況にあり、この為、浚渫船等により定期的に維持
浚渫しているが莫大な費用を要し、港の一部を占有する
など問題が多い。Due to this siltation phenomenon, the water depths of shipping routes and anchorages become shallower year by year, which may hinder the navigation of ships. Therefore, maintenance dredging is regularly carried out by dredging vessels, but enormous cost is required. In fact, there are many problems such as occupying a part of the port.
【０００４】また、ダム湖等でも、同様に土砂の堆積が
問題になっている。Further, sedimentation of sediment is also a problem in dam lakes and the like.

当たらない。For this reason, there have been devised and implemented methods for forcibly creating a water flow by a pump or the like by means of power to try to flow sediment, and methods for preventing siltation by devising the structure of breakwaters. I can't find a way to dredge it regularly and permanently.

とを最も主要な特徴とする。Means for Solving the Problem The present invention uses seawater or water introduced from the upstream of a dam lake or the like by utilizing the tidal difference due to the tidal tide to store it in a reservoir or a water tower by a dam,
The valves installed at the intake and discharge ports are automatically opened and closed by weights, and when the water level difference occurs, water is discharged, and the sediment is deposited and dredged using an ejector that utilizes the so-called Venturi effect, depending on the flow rate, and can be disposed of. The most important feature is that it is possible to lead to and discharge to any place using only natural energy.

With the ejector using the flow velocity, it was possible to suction and dredge the sediment that has flowed into the bottom of the water, and to guide it to a place where it can be disposed of through the discharge pipe to discharge it.
