System for removing riverbed silt sediments by diverting seawater
The invention relates to a system for removing riverbed silt sediments by diverting seawater. The system includes seaside flood seawater, a tidal lake enclosed by a causeway on the beach, and a lagoon below the tidal lake. The tidal lake is connected with the lagoon through a lagoon gate. When the tide level rises, a channel between the tidal lake and the lagoon is cut off through the lagoon gate, and the lagoon acquires high-water-level washing water sources. A water gate is arranged between the upstream and the downstream of the rivers, the upstream in the front of the water gate is diverted, and a river weir is arranged at the outlet position o the diverted channel. The downstream of the river weir is divided into a connection river channel connected with the lagoon and a scour channel connected with the downstream of the river, and the scour channel is converged with the downstream of the river. The system has the advantages that the seawater sources are led in so silt sediments on the bed of the downstream of the rivers can be washed by twice by tides in one day, and when the upstream of the rivers has flood, the flood can flow over the river weir, flow towards the connection river channel, the lagoon and the lagoon gate, then flow over the seawater weir and finally be drained into the sea.
