In addition, when the inverted siphon is overhauled, the sluice should descend the sluice to intercept the downstream water level. Therefore, the sluice should satisfy two kinds of operating condition of improvement water pressure manger plate and the inverted siphon overhauls manger plate. The water gate has the two-way water retaining function by being used as a working gate when the water pressure water retaining function is improved and being used as an overhauling gate when the water retaining is overhauled, and the key is to judge whether the two-way water retaining can be realized by the water gate. The existing gate water stopping structure generally only meets the one-way water stopping function under a single working condition and cannot meet the two-way water stopping function. Therefore, the prior art has shortcomings and needs to be improved.
