Water storage tide gate capable of automatically sensing tide and construction method of water storage tide gate

The invention discloses a water storage tide gate capable of automatically sensing tide and a construction method thereof, and belongs to the field of water conservancy projects. Comprising a concrete base and further comprises a plurality of concrete blocking gates, a plurality of reinforcing columns are fixedly connected to the concrete blocking gates, the concrete blocking gates are located on the concrete base, a concrete supporting seat is fixedly poured on the concrete base, and a hydraulic push rod is rotationally connected to the concrete supporting seat; the driving end of the hydraulic push rod is rotationally connected with the reinforcing column; at the moment, the umbrella-shaped gates are tensioned by the pulling cylinder through the steel wire rope, the umbrella-shaped gates are folded, a flood discharge channel formed between every two adjacent umbrella-shaped gates is contracted, a large amount of tide water is effectively prevented from flowing back from the flood discharge hole, the umbrell
