PURPOSE: A floodgate device is provided to stably operate a floodgate facility and to prevent water leakage by preventing vibration applied to a roller gate. CONSTITUTION: A floodgate device comprises a roller gate(100), a pump unit(200), a bypass passage(300), a sub gate(400), and a driver(500). The pump unit forcibly discharges internal water by being separately installed from the roller gate. The bypass passage is equipped for discharging the internal water which flows into a drain(10) through the pump unit without passing through the roller gate. |
