[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] like Figure 1As shown, the pumped storage power station incorporates an escape hydraulic structure with a maintenance gate tunnel and a construction adit, including an inlet / outlet maintenance gate tunnel 3. The first end of the inlet / outlet maintenance gate tunnel 3 is connected to a construction adit 6. During the excavation phase of the inlet / outlet maintenance gate tunnel 3, the construction adit 6 serves as a construction passage. After the completion of the inlet / outlet maintenance gate tunnel 3, it is structurally modified to form a permanent escape passage. A staircase 5 is installed inside the inlet / outlet maintenance gate tunnel 3, and the staircase 5 is connected to the construction adit 6.
