Problems solved by technology

[0004] Due to the complex water flow conditions of the two-stage stilling basin in the downstream of the barrage, the project volume of the reconstruction plan for risk removal is relatively large, and the project investment is relatively large. In addition, there are many restricted conditions and inconvenient construction during the construction of the project transformation. Therefore, it brings certain difficulties to the reconstruction of energy dissipation works downstream of numerous barrages.

Abstract

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.

Description

Technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a method for eliminating dangers of energy dissipaters downstream of a stilling pond. Background technique [0002] The current low-head sluice flood discharge and energy dissipation mostly use undercurrent energy dissipation, that is, set up a stilling pool, flood section and anti-scouring trough downstream of the sluice, and use the stilling pool to dissipate energy and use the flood section to reduce energy. Remaining water flow energy downstream of the stilling pool, adjust the flow velocity distribution, make the water flow evenly spread, etc., to reduce the erosion of the downstream river bed by the discharge, the specific structure can refer to figure 1 . [0003] At present, due to the undercutting of the river bed and the lowering of the water level in the downstream sluices, the energy dissipaters in the downstream of the sluices are in danger (such as the flooding...
