Danger-elimination refitting method for stilling pool downstream energy dissipater
The invention discloses a danger-elimination refitting method for a stilling pool downstream energy dissipater. The stilling pool downstream energy dissipater comprises an apron extension section and an anti-scour trench which are sequentially arranged. A tail ridge is arranged at the tail end of a stilling pool. The method includes the following steps of laying reinforced concrete used for reinforcement on the surface layer of the slope apron extension section, arranging a plurality of continuous stilling ridges on the slope apron extension section, and arranging an anti-scour key wall at the tail end of the slope apron extension section. The optimized stilling ridge arrangement method for the downstream apron extension section is obtained through danger-elimination reinforcement and refitting of the downstream stilling pool of a river sluice in danger, according to the tail ridge arrangement of the downstream stilling pool and on the basis of reinforcing the downstream apron extension section in danger, a new route is created for danger-elimination refitting of a plurality of river sluice downstream energy dissipaters which are low in water level due to downward river bed downcutting of downstream river channels, the project amount and investment can be greatly saved, and safety of project running is ensured. The danger-elimination refitting method for the stilling pool downstream energy dissipater can be widely applied to the field of hydraulic engineering.
