在宁波市十七处下穿通道雨水泵站升级改造工程设计中,发现下穿通道雨水泵站均存在不同程度“扩容改造难”的问题。在分析原因后,建议在新建下穿通道雨水泵站时,采用工程项目生命周期理论,对雨水泵站系统不同的组成部分采用差异化标准,同时设计时融入“便于养护和升级改造”的理念。 In the design and construction of the rainwater pumping station under the through-going rainwater pumping station in Ningbo City, it was found that the rainwater pumping station under the through channel had different degrees of difficulty of “expansion and reconstruction”. After analyzing the reasons, it is recommended to adopt the life cycle theory of engineering project to adopt differentiated standards for different components of rainwater pumping station system when new underpass rainwater pumping station is built, meanwhile, it is suggested to incorporate “easy maintenance and upgrading” Concept.
