Abstract

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.

Description

technical field [0001] The invention relates to the technical field of spillways, in particular to a novel arc cylindrical side wall spillway energy dissipation system. Background technique [0002] Reservoirs are used as water conservancy engineering buildings to hold back flood water and regulate water flow, and can be used for irrigation, power generation, flood control and fish farming. It can play the role of flood control, water storage for irrigation, water supply, power generation, fish farming, etc. It plays an important role in the development of the national economy. As the flood discharge structure of the reservoir - the spillway, it is used to vent the flood that cannot be accommodated by the planned storage and to ensure the safety of the dam body. Spillways generally do not work very often, but are important structures in reservoir junctions. [0003] Due to the steep slope of the spillway steep trough, the main characteristics of the water flow in the trou...
