《河南水利与南水北调》2023年第2期施工技术大坝碾压混凝土埋设件施工技术胡险(江西省水投建设集团有限公司,江西南昌330000)摘要:埋设件施工内容是大坝碾压混凝土施工的重要组成部分,科学应用埋设件施工技术原理实施高质量施工,对大坝碾压混凝土施工整体达到设计要求具有不可或缺的作用。埋设件施工内容主要包括:接触灌浆管路、坝体排水孔、冷却水管及观测仪器预埋件埋设等。结合某大坝碾压混凝土施工案例,针对碾压过程中有观测仪器和设施等埋件的部位进行浇筑时,埋设件应安装准确,加固稳妥,并加以明确而醒目的标记和妥善保护,其周围采用人工铺料浇筑的方法施工。对碾压后挖坑槽埋设的仪器、电缆,需控制坑槽深度,以保证在仪器安装就位后最少有20cm厚的人工回填混凝土保护层,同一仓块浇筑的碾压混凝土初凝前完成回填以确保密实性。水库枢纽大坝埋设件技术高质量施工对类似工程建设具有参考借鉴意义。关键词:大坝碾压混凝土;埋设件施工技术;高质量应用中图分类号:TV5文献标识码:A文章编号:1673-8853(2023)02-0047-02ConstructionTechnologyforEmbeddedPartsofDamRCCHUXian(JiangxiWaterInvestmentConstructionGroupCO.LTD.,Nanchang330000,China)Abstract:TheconstructioncontentofembeddedpartsisanimportantpartofdamRCCconstruction.Thescientificapplicationoftheconstructiontechnologyprincipleofembeddedpartsistoimplementhigh-qualityconstruction,whichplaysanindispensableroleinachievingtheoveralldesignrequirementsofdamRCCconstruction.Theconstructioncontentofembeddedpartsmainlyincludes:contactgroutingpipeline,damdrainagehole,coolingwaterpipeandembeddedpartsofobservationinstrument.Combinedwiththeconstructioncaseofadam'srollercompactedconcrete,theembeddedpartsshallbeinstalledaccurately,reinforcedreliably,clearlyandconspicuouslymarkedandproperlyprotectedwhenpouringthepartswithobservationinstrumentsandfacilitiesduringtherollingprocess.Thesurroundingpartsshallbeconstructedbymanualpavingandpouring.Fortheinstrumentsandcablesburiedinthetrenchafterrolling,thedepthofthetrenchshallbecontrolledtoensurethatthereisatleast20cmthickmanualbackfillconcreteprotectivelayeraftertheinstrumentisinstalledinplace.Thebackfillshallbecompletedbeforetheinitialsetti...
