某新建高位水池消能改造方案及应急措施研究OA

after a new high-level water tank was built and operated,there were two kinds of bad flow patterns:one was water spraying at the outlet of the vent,the other was abnormal aeration at the downstream water plant.In this paper,the flow pattern and aeration condition in the newly built high-level pool are demonstrated by hydraulic model test,and the flow turbulence and aeration mechanism in the pool are studied,the energy dissipation scheme of"Critical water level"after Weir is verified and put forward,which can eliminate the bad flow pattern in high level pool in short term;After compared and analyzed several energy dissipation schemes such as opening holes in the middle and bottom of the weir plate,for the weir plate of the high level water pool,and the optimized scheme proposed was relatively good in the flow state and energy dissipation effect,which could be used as a feasible implementation scheme for the structural transformation of the high level water pool.The experimental results can provide reference for similar engineering design.
