PURPOSE:To obtain a gate of a proper height as well as make transportation and housing of gate parts easier by using a gate body consisting of plural rectangular or cubic unit blocks which are divided horizontally. CONSTITUTION:A gate body 1 is made up of plural rectangular or cubic unit blocks 2 which are divided horizontally and connecting metals 3 to connect the sideward centers of the unit blocks 2. A watertight rubber is provided between the blocks 2, a pressure-supporting plate 9 having a water tightness is attached to both-side contact edge portions of the gate body 1, and a water- stop rubber is attached to the upper and lower contact edge portions of the body 1. Wires A and E are provided to the upper and lower parts of the body 1. The gate body 1 is rotationally settled and contacted with the port D of an orifice C. The transportation and housing of the gate body 1 can be made easier by plural unit blocks 2, and a proper height of the gate can be obtained by controlling the numbers of the blocks 2.
