However, due to the influence of inertial force, the water flow in the forebay of lateral drainage is easy to produce backflow and vortex. If no rectification measures are taken, the efficiency of drainage will often be affected. destroy. In water supply or irrigation projects, the pump gates are often arranged side by side for water diversion, and the pump gates are separated by partition walls. When the flow direction is from the pump side to the gate side or vice versa, the lateral drainage of the sluice is blocked by the partition wall, and it is easy to generate a backflow area near the side hole of the partition wall, which affects the drainage of the side hole of the sluice, and the vortex generated at the same time is easy to Beach surface caused scour. Therefore, it is very necessary to take reasonable and economical engineering measures to improve the flow pattern of water flow.
