高水头弧形闸门伸缩式水封止水试验研究

Study and Test of Expansion Type Water Seals for High Water Head Tainter Gates

基于小湾水电站高水头闸门水封止水试验,对伸缩式水封的工作原理和止水效果进行了研究。试验证明,如果伸缩式水封及压板体型选择合理、材质选择合适,则可以满足承压水头200 m的止水要求。对伸缩水封的设计、制作和运行提出建议,以供工程参考。

This paper makes a study of operating principle and sealing effect of the expansion type water seal based on the water sealing test of the high water head gate for Xiaowan hydropower project. The test results have proved that the expansion type water seals can meet the requirement of water sealing under a bearing water head as high as 200m provided the configuration, shape and material quality of beth expansion water seal and clip plate are properly selected. The paper also puts forward suggestions on design, fabrication and operation of the expansion water seals for reference.
