PURPOSE: A floodgate is provided to prevent water pollution due to the blockage of a drainpipe by forcibly crushing, pressurizing, and discharging soil through the reciprocation of a shaft. CONSTITUTION: A floodgate comprises floodgate body(10), a driver, and an undertow water discharging unit(40). The undertow water discharging unit comprises a drainpipe(100), a rotary cylinder(42), and a blocking plate(44). The drainpipe comprises an inlet(110), a horizontal part(120), and an outlet(130). The horizontal part comprises first and second pressurization parts(200,300). The first pressurization part moves downstream for pressurizing and transferring soil. The second pressurization part pressurizes the soil transferred from the first pressurization part for discharging to the downstream of the floodgate body. The first and second pressurization parts are formed with rails(260,360), is installed with carriages(230,330) mounted with a motor to be movable on the rails. Shafts(240,340) are joined to a motor shaft. |
