PURPOSE: A composing method of an automatic sluice with a double compressing bar is provided to maintain water level with a specific range by automatically drain and reserve water. CONSTITUTION: An automatic sluice comprises a pair of supports(1) mounted on both sides of a sluice(7); a hinge shaft connected to the support to slantingly form the sluice on the support; a rotating unit(5) having a rotation shat(5) to rotate the sluice; a wall body(8) installing te rotating unit; an upper end compressing bar controlling opening and closing the sluice of the rotation shaft; and a lower compressing bar(4) combined with the sluice by a moving hinge(3). The wall body and the sluice body is formed as a square plate shape of a hollow, and filled with helium gas generating buoyance inside of the sluice. The rotation shaft mounted both sides of the sluice is arranged on drain water side between the wall body to slantingly form the face of reserve water side with a sluice floor. Moreover, the sluice body is rotatably combined to the pillar by the hinge.
