Description

Technical Field

[0001] The utility model relates to the technical field of energy dissipation pools, in particular to a buffer type energy dissipation pool. Background Art

[0002] In the construction of water conservancy and hydropower projects, overflow dams are a very common dam type, such as sluice dams, overflow gravity dams, etc. In order to meet the needs of energy dissipation and anti-scouring, it is often necessary to arrange energy dissipation projects behind the overflow dam to reduce the huge kinetic energy of the water flow caused by the water level difference between upstream and downstream.

[0003] The energy dissipation pool is a pool-shaped energy dissipation facility that can cause an underflow hydraulic jump downstream of the discharge structure. It can quickly turn the downstream rapids into slow flows, generally eliminate 40% to 70% of the kinetic energy of the downstream water flow, and shorten the length of the guardrail. It is an effective and economical energy dissipation facility. Most of the existing energy dissipation pools have energy dissipation thresholds set on the guardrail (usually at the end) to slow down the water flow.

[0004] However, in the existing technology, most of the stilling sills will be subjected to long-term hydraulic erosion. After a certain period of time, safety hazards such as local concrete aging, exposure of coarse aggregate, and rust of steel bars may appear on the surface of the stilling sill. After long-term use, they need to be replaced, and the overall replacement cost is relatively high. Utility Model Content
