摘要
在上海市南区污水输送干线改建工程的基础上,合理利用原改造方案中2～3号泵站间管线采用顶管施工,以一级倒虹代替多级倒虹的水力条件改善来进一步进行泵站优化设计。经多方案综合比较后得出取消2号泵站并新建3号泵站为优选方案,使其改造方案更为合理,改建费及经常运行费用均更省,也方便了管理。
In the south waste water delivery main line modification project, due to using jacking process to replace multiple inverted siphons with once inverted siphon, hydraulic condition was improved, which made design optimization of pump station possible. After comparing, the optimized alteration was to cancel No.2 pump station and rebuild No. 3 pump station. It made the modification more reasonable and reduced the reconstruction cost.
