| 摘 要： | 针对泵站运行中前池存在水流紊乱以及泥沙淤积等主要工程问题，提出：根据水源水位变幅大小，合理选取扩散角和底坡是前池设计中的关键环节。介绍了聊城市泵站建设及改造中对不同情况采用的改善前池工作条件的工程措施。实践证明：在扩散型前池中建成倒坡池底；泵站若是侧向引水或部分机组运行，设置纵向导流墙；如果引水渠渠底与进水池池底高程相差较大且前池又较短。在池底斜坡上修建横坎。都是改善池中水流扩散和减少泥沙淤积的有效办法。

| Abstract: | The reasonable spread angle and slope based on the amplitude of source water level variation are critical for the front pond design to solve the problem of disorderly streams and muddy filling in the pond during pump station operation. The various methods applied during the construction or retrofit of pump stations in Liaocheng city are presented. Project practice proves: a horrent slope for the spread type pond, a torrent-leading wall for pump station of side torrent-leading and part unit working, and ridges built on the slope for short pond that has a rather big difference in bottom elevation with the feeder canal are all effective methods to improve the spreading torrent and reduce muddy filling. |
