<p>A method for forming a water gate for purifying polluted water into clean water is provided to purify water by discharging bottom water of a water storage space through a lower space of a water gate while a water gate is closed, thereby discharging pollutants such as deposited sludge together with the discharged water. A method for forming a water gate for purifying polluted water into clean water comprises the steps of fixing a connecting link(50) to a waterway of a driving shaft(30), connecting a rotary shaft(21) of a water gate(20) to the other end of the connecting link to be rotatable, forming loops(22) on right and left sides of the top of the water storage side of the water gate, connecting a piston rod(62) of a traction cylinder(61), which is fixed to a side wall of a support structure to be rotatable, to each loop by a rope(63) to open and close the water gate according to the expansion and contraction of the traction cylinder, and leaving space between the water gate and the bottom of the waterway according to the expansion and contraction of an operating cylinder(41) to discharge bottom water of a water storage space, thereby to purify water.</p> |
