Zusammenfassung:A gate for an irrigation ditch includes a rectangular frame, in which a pair of gates are pivotally mounted on shafts for rotation around vertical axes at the sides of the frame; helical springs connected to the top ends of the shafts and to the frame for regulating the water pressure required to open the gates; and tensioning elements for changing the length and consequently the tension of the springs, so that the pressure required to open the gates can be adjusted.
