摘要
进水孔口形成的吸气漏斗漩涡,对水工建筑物危害性很大.在总结进水孔口漏斗漩涡形成原因和消涡措施的基础上,通过试验提出了一种针对孔口向前伸入水库的底孔进水口专用消涡设备(消涡器),其结构简单、便于施工、经济实用,用于消除底孔前伸的进水孔口前游弋不定的漩涡,效果良好,可供工程设计和管理运行参考.
Funnel-shaped suction eddies in front of the bottom entrance greatly endanger the hydraulic structure. Based on investigating the cause of these eddies and their elimination measures, an eddy-eliminating system has been developed for a moving forwards bottom entrance. It is simple in structure, easy for construction, economical and practical for use, enabling to efficiently eliminate the above eddies and this experience can be used for other projects.
