In this project, the elevation angle of the deep hole is 64M, the design head of the hole center is 35.9m, and the hole section is a rectangular section with a height of 5m and a width of 5m. Upstream is pressure section, followed by open flow. The dam surface of the open flow section is a horizontal section, followed by a reverse arc, which makes the bridge smooth and dissipates energy in the form of surface flow. The height of the bridge of the nose is 64M. The bulkhead gate is a radial gate set at the pressure outlet end. A ventilation hole with a diameter of 1 m is set behind the plane gate, and the outlet starts from the downstream dam face.
