摘要
介绍南水北调东线第一期工程沿线泵站清污机桥的现状和规划，计算了3～6m宽回转式清污机的主要参数，通过对清污机桥阻水率、每延米长造价的分析比较，结合工程经验，推定清污机桥合理、经济的孔口宽度为4．5～5m。
This article introduces the status quo of bridges for trash-eliminating machine, calculates the main parameters of trash-eliminating machine between 3 to 6 meter spans By comparing the rate of water blocking, the price of per meter, referring designing experiences of many pump stations, the writer concludes the economic span of bridge for trash-eliminating machine is 4. 5 to 5 meter.
