PURPOSE: An environment-friendly construction method for purifying polluted river water using the effect of gravity generated depending on the mass of water molecules is provided to naturally purify polluted river water without physical, chemical, and biological treatment. CONSTITUTION: An environment-friendly construction method for purifying polluted river water using the effect of gravity generated depending on the mass of water molecules comprises working devices(2), a first lower water discharging device, and a second lower water discharging device. The working devices are formed in both sides of a concrete footing in order to operate a floodgate(1). The first lower water discharging device discharges lower water by opening the bottom end of the floodgate. The second lower water discharging device lifts the bottom end of the floodgate. |
