PURPOSE: A waterway opening and closing device is provided to improve an ecological environment and to prevent the opening and closing of a water gate from being disturbed due to floating foreign substances by being environmentally friendly to a surrounding ecological environment while being opened or closed. CONSTITUTION: A waterway opening and closing device comprises a water gate(10), a bottom frame(30), and a fall inducing plate(40). The water gate is installed in the outlet(4) of a waterway(2) in order to open and close the waterway. The bottom frame is installed on the bottom surface of the outlet and is equipped with an introducing groove(32) for introducing the water gate and flattening the bottom surface of the outlet when opening the water gate. The fall inducing plate is protruded towards the front side of the water gate and allows overflowed water through the top of the water gate to perpendicularly fall towards the introducing groove in the closed state of the water gate. |
