The invention discloses a novel
spillway energy dissipation
system with an arc-shaped cylindrical side wall. The novel
spillway energy dissipation
system slightly scours downstream riverways and
bank slopes, has a low cost, a simple and compact structure and high
flood discharge capacity, is free from flood atomization, shortens the length of a downstream stilling
pool, has a long service life, is resistant to
impact, is high in durability, and organically combines energy dissipation by trajectory jet, ladder energy dissipation, arc-shaped cylindrical side wall energy dissipation, energy dissipation by surface flow and energy dissipation by underflow into a whole. The novel
spillway energy dissipation
system consists of a transition section, a step, an arc-shaped cylindrical side wall, a flip bucket, sawteeth and an energy dissipation
ridge. A
water flow reaches the step and the arc-shaped cylindrical side wall section through the transition section, the flip bucket is connected to the
tail end of the step to pick the
water flow to the downstream sawtooth section, the energy dissipation
ridge is connected behind the sawtooth section, and the
water flow finally enters the riverway through the energy dissipation
ridge.
