In the stilling pool tail sill structure adopting the bottom holes for sand discharge, the outer surface of the steel lining is provided with the reinforcing ribs, and the reinforcing ribs are fixed in the tail sill.
The stilling pool tail sill structure adopting the bottom hole for sand discharging is characterized in that a flap gate is arranged in the bottom hole of the tail sill, a rotating shaft is arranged in the middle of the flap gate, two ends of the rotating shaft are movably connected to two sides of the inner wall of the bottom hole of the tail sill, one side of the flap gate is connected with a spring, and one end of the spring is movably connected to the hole wall of the bottom hole of the tail sill.
In the stilling pool tail sill structure adopting the bottom hole for sand discharge, the sleeve is arranged on one side of the flap gate, and the spring is arranged in the sleeve.
The invention has the beneficial effects that:
1. compared with the existing stilling pool, the stilling pool has the advantages of thoroughly solving the problem of sand discharge, and can be used as a hydraulic and hydroelectric project for dissipating energy by adopting the stilling pool in a river with much sediment;
2. the tail sill bottom hole adopts the design that the section is trapezoidal, so that the aperture of a water inlet end is smaller than that of a water outlet end, the water inlet capacity of the tail sill bottom hole is smaller than that of water drainage capacity, and the energy dissipation effect of the tail sill bottom hole is improved;
3. according to the invention, the steel lining is arranged in the bottom hole of the tail sill, so that abrasion damage of silt to the bottom hole of the tail sill can be prevented;
4. the reinforcing ribs are arranged, so that the combination of the steel lining and the bottom hole of the tail sill is firmer;
5. in order to ensure that water exists in the stilling pool and reduce the damage to the stilling pool during small-flow flood discharge, the invention is provided with the flap door inside the bottom hole of the tail sill and can rotate around the middle rotating shaft, the back of the flap door is supported by a spring with larger elasticity, the outer part of the spring is provided with a sleeve for protection, the spring is provided with thrust below the top elevation water level of the tail sill, namely the flap door is closed when the stilling pool is not flooded, and the water in the stilling pool is ensured.

Detailed Description
The invention is further illustrated by the following figures and examples, which are not to be construed as limiting the invention.
The embodiment of the invention comprises the following steps: a stilling pool tail sill structure adopting bottom holes for sand discharging is shown in the attached drawing 1-2 and comprises a flood discharge channel 1 which inclines downwards, the bottom end of the flood discharge channel 1 is connected with a stilling pool bottom plate 2, a tail sill 3 is arranged at the tail end of the stilling pool bottom plate 2, tail sill bottom holes 4 are arranged at the bottom of the tail sill 3 (the height of the tail sill bottom holes 4 is not more than 1/3 of the height of the tail sill 3, and one tail sill bottom hole 4 is arranged every 7 to 0 1m in width), and the lower end faces of the tail sill bottom holes 4 are flush with the upper end face of the stilling pool bottom plate 2 or lower than the upper end face of the stilling pool bottom plate 2.
The section of the bottom hole 4 of the tail sill is trapezoidal, and the aperture of the water inlet end is smaller than that of the water outlet end.
And the hole wall of the tail sill bottom hole 4 is provided with a steel lining 5 which is consistent with the shape and the size of the inner wall of the tail sill bottom hole.
And reinforcing ribs 6 are arranged on the outer surface of the steel lining 5, and the reinforcing ribs 6 are fixed in the tail sill 3.
