1、摘要江苏省白水荡原属排涝泵站装机容量小,排涝能力低,远不能满足整个排区的需要。本泵站的兴建能确保该地区的排涝灌溉要求,有力地促进该地区工农业生产及经济发展。本泵站采用2台套900ZLB-85型轴流泵,泵站设计排涝流量为4.6m3/s,正向进水,正向出水,具有抽排功能。本设计可概括为四个部分,第一部分:机组选型;第二部分:整体布置;第三部分:稳定计算;第四部分:结构计算。泵站系由站身段、上游连接段及下游连接段等三部分组成。站身段包括底板、闸墩、泵房、进水池、工作桥等;上游连接段包括前池、上游翼墙及上游护坡等三部分组成;下游连接段包括出水池、下游翼墙及下游护坡等三部分组成。本泵站的泵型为立式
2、轴流泵,泵房形式采用墩墙式湿室型泵房,泵站场地土类别为Ⅲ类,不能满足稳定要求和地基力要求,本泵站采用钻孔灌注桩来解决此问题。在工程上部结构施工中和投入使用后应进行地基沉降观测。关键词:泵站立式轴流泵设计流量排涝墩墙式湿室型AbstractBaishuidangDrainagePumpingStationProcincehadinstalledsmallcapacityofpumpunitsinjurongofJiangsu,thedrainagecapacityofthepumpingstationwasfarfrombeingabletomeetthedrainageneedsofth
