Safety protection structure and method for long fishway and high slope vertical cross operation

The invention provides a safety protection structure and method for long fishway and high slope vertical cross operation. The structure comprises a slope, the gradient of the slope is 70-80 degrees; a top construction face is arranged at the top of the slope; a bottom construction face is arranged at the bottom of the slope; the slope is provided with a springboard protection layer and a flexible net protection layer from top to bottom; the height difference between the flexible net protection layer and the bottom construction face is 30-40 m; the height difference between the springboard protection layer and the flexible net protection layer is 15-20 m; and the height difference between the springboard protection layer and the top of the slope is 2-10 m. Through double-layer safety protection, the structure is simple, the application range is wider compared with a traditional protective shed, and the safety protection structure is especially suitable for high slope terrains; and the safety is high, and the u
