The present invention relates to a movable weir for removing sludge on the bottom. Sludge generated on the surface of a bottom frame is removed by using a plurality of injection nozzles assembled on one side of the inside of a sluice of the movable weir. A round groove is formed on the front surface of the injection nozzle in order for water pressure discharged from the injection nozzle to be effectively injected. A hexagonal groove for assembling the injection nozzle in a pipe is formed on the center, and a hole for discharging the water is formed on the hexagonal groove. Therefore, the movable weir for removing the sludge on the bottom can remove organic sludge. |
