深圳污水主干管渠及泵站工程设计优化

深圳污水主干管渠及泵站工程设计优化彭书郁(深圳市市政设计研究院，深圳518035)摘要介绍深圳长20．5km的污水主干管渠和滨河泵站(10万m3／d)，新洲泵站(10万m3／d)，凤塘泵站(38万m3／d)的工程设计优化情况。主干管渠设计中注意了控制埋深，避开填海区，缩短压力管，污水截流管离开沿河岸区，管道与河道相交的做法以及运用顶管施工技术等。提升泵站采用潜水泵，取消压榨机，外观美化等措施。工程竣工数年，运行良好。关键词污水主干管渠提升泵站优化深圳市OptimizeddesignofsewermainandpumpingstationsinShenzhenPengShu—yu(MunicipalEngineeringDesignandResearchInstitute，Shenzhen518035，China)Abstract：Themajorizeddesignsofasewermainpipeandcanal(totaldistance20．5km)andthreepumpingstationsnamelyBinhe(capacity10×104m3／d)，Xinzhou(capacity10×104m3／d)andFengtang(capacity38X104m3／d)inShenzhenaredescribed．Inthesewermainpipeandcanaldesign，problemslikecontroloflayingdepth，avoidanceoflayoutinareaofseareclamationorriversidealongandcutdownthedistanceofpressurizedlineweretakenintoconsideration．Besidethesealsomeasuresofpipecrossingriverandthepipepushingconstructionwereproposed．Submergedpumpassemblieswereadoptedfortheboostingpumpingstationswithdecoratedarchitecturedesignandtheslagpresswasignored．Thisprojecthasbeenoperatingforyearsnorma
