PURPOSE: An environmentally-friendly construction method to purify polluted river water using a cutting edge floodgate system is provided to naturally purify polluted water by discharging contaminants such as deposited sludge. CONSTITUTION: An environmentally-friendly construction method to purify polluted river water using a cutting edge floodgate system is as follows: A floodgate(1) is slightly tilted downward to produce water pressure. One end of an actuating link(8) is rotatably fixed to a shaft of a driving device and connected to the bottom of the floodgate. A cylinder or a winch(21) connected with a rope(34) is formed on the top of the floodgate so that the floodgate is upright. When the floodgate is upright, the driving device is slightly lifted, and a discharge passage is formed between the bottom end of the floodgate and a floor part of a waterway. Dense river water is primarily discharged. |
