建筑施工·第45卷·第1期139新型预制装配式结构体系在水处理构筑物中的应用技术研究胡董超上海建工二建集团有限公司上海200090摘要:在面对大型的地下污水处理厂大型水池等特殊结构时,现有的预制板或预制墙由于其相对较大的跨度、高度以及较高的防水防腐要求,因而存在较多局限。为解决上述问题,结合上海竹园污水处理厂四期工程1.5标项目的工程实践,详细介绍了预制“双面叠合剪力墙+倒T板”,节点形式采用UHPC连接的新型预制装配式施工技术在地下污水处理厂中的运用。采用HDPE锚固板防腐层与构件一同预制的防腐措施,可为今后大型污水处理厂预制装配式结构工程的施工提供参考。关键词:预制双面叠合墙;预制倒T板;超高性能混凝土;HDPE锚固板中图分类号:TU755文献标志码:A文章编号:1004-1001(2023)01-0139-05DOI:10.14144/j.cnki.jzsg.2023.01.036ResearchonApplicationTechnologyofNewPrefabricatedStructureSysteminWaterTreatmentStructuresHUDongchaoShanghaiConstructionNo.2(Group)Co.,Ltd.,200090,Shanghai,ChinaAbstract:Inthefaceofspecialstructuressuchaslargepoolsinlargeundergroundsewagetreatmentplants,theexistingprefabricatedslabsorwallshavemanylimitationsduetotheirrelativelylargespan,heightandhigherrequirementsforwaterproofandanti-corrosion.Inordertosolvetheaboveproblems,combinedwiththeengineeringpracticeofSection1.5ofShanghaiZhuyuanSewageTreatmentPlantPhaseⅣProject,thispaperintroducesindetailtheapplicationofthenewprefabricatedconstructiontechnologyofprefabricated"double-sidedlaminatedshearwall+invertedT-plate",withthenodeformofUHPCconnection,intheundergroundsewagetreatmentplant.Theanti-corrosionmeasuresofprefabricatingHDPEanchorplateanti-corrosioncoatingandcomponentstogethercanprovidereferencefortheconstructionofprefabricatedstructuresinlargesewagetreatmentplantsinthefuture.Keywords:prefabricateddouble-sidedlaminatedwall;prefabricatedinvertedT-plate;ultrahigh-performanceconcrete;HDPEanchorplate平流式二沉池AAO生物反应池平流式二沉池AAO生物反应池预制装配施工区域污水泵房雨水泵房碳源投加间图1装配式施工范围示意单个预制装配式区域长47.7m,宽51m,面积约2400m2,层高10.1m。预制范围包括预制混凝土墙、预制混凝土梁、预制混凝土板等构...
