Partial plunge pool type stilling basin
The invention relates to a water conservancy facility, and specifically relates to a partial plunge pool type stilling basin. The partial plunge pool type stilling basin sequentially comprises a drop sill, a front shallow-water cushion, a plunge pool, a rear shallow-water cushion, an end sill and a downstream apron, wherein the front shallow-water cushion is connected to the bottom part of the drop sill; the sunken plunge pool is arranged at the rear side of the front shallow-water cushion; the uplifted rear shallow-water cushion is arranged at the rear side of the plunge pool; the end sill is arranged at the rear side of the rear shallow-water cushion. According to the partial plunge pool type stilling basin, the front shallow-water cushion and the rear shallow-water cushion of the stilling basin can perform the buffering function of a water cushion of the general stilling basin when the downstream water is at high level; the plunge pool in the middle can form a deep water cushion for the discharged water. Therefore, the water swirly rolls in the plunge pool and cannot indirectly impact a bottom plate of the stilling basin, and the speed of the water running close to the bottom can be effectively reduced; the rest energy can be dissipated again when the water runs through the end sill in the downstream, so that the bottom plate of the stilling basin can be certainly protected while good energy dissipating effect is ensured; the partial plunge pool type stilling basin is high in adaptability to the discharged flow.
