The embodiment provides a water sluicegate, including stand 20, flashboard 30, stand 20 is equipped with spout 21, and flashboard 30 can slide along spout 21, in addition, still includes side sealing strip 40, and side sealing strip 40 is fixed in the seam crossing of stand 20 and flashboard 30, and side sealing strip 40 has 0.5mm-1.5 mm's compression capacity for flashboard 30. Specifically, referring to fig. 4, the gate 30 is covered with the wear reducing strips 33, and the side water stop strips 40 are tightly attached to the outer surfaces of the wear reducing strips 33. Specifically, the contact surface of the side water stop strip 40 and the gate 30 is a first water stop surface 41, and the side water stop strip 40 has a compression amount of 0.5mm to 1.5mm relative to the first water stop surface 41. In fig. 4, a broken line indicates that the gate has a certain amount of compression in the direction of the shutter 30. The water conservancy gate provided by the utility model is only provided with the side water stop strip 40 on one side, and particularly, is only provided with the side water stop strip 40 on the downstream side.
