The number of the vibration examples of the gate caused by water leakage of the gate is not small, and the problems of unsuitable water sealing type, water sealing installation error, ageing of water sealing materials and the like are caused. For the down-the-hole planar gate for upstream water stop, the water stop type is usually a P-type water seal or a mountain-type water seal, if the water seal cannot be completely sealed, under the action of upstream water pressure, the water seal at the top of the gate leaks greatly, and water flow ejected from the top of the gate stops the beam grid behind the gate leaf, so that the gate vibration is easily caused, and the safe operation of the gate is influenced. Therefore, how to ensure the sealing performance of the water stop, so as to avoid the vibration of the gate caused by water leakage of the water stop is a key problem to be solved at present.
