四方面分析如何做好排水管道工程施工质量管理摘要：从施工准备阶段、管道施工阶段、管线安装、检查井施工以及土方回填和闭水试验等方面论述了市政给排水管道工程施工质量管理重点及措施。Pickto:basedontheconstructionpreparationstage,stageofpipelineconstruction,pipelineinstallationandconstructioninspectionWellsandearthworkbackfillandclosedwatertestandsoondiscussesthemunicipalwatersupplyanddrainagepipelineengineeringconstructionqualitymanagementemphasisandmeasures.关键词：市政；给排水；管道Keywords:municipal;Watersupplyanddrainage;pipeline一、施工准备阶段质量控制Apreparationphase,constructionqualitycontrol（一）道路拆除与恢复?市政给排水管道施工必然涉及到一定路面的拆除与恢复工作，为了能够保证施工安全及路基质量，在道路开挖前应根据施工图纸计算开口宽度，用白漆标出开挖线之后用切割机将路面切断，用挖掘机对破碎的混凝土路面及碎石等垫层进行开挖并合理堆放以备后用，管路施工完成后的沟槽回填工作直接影响路面的质量及使用功能，尤其是在高原地区更应注重沟槽回填质量，一般对回填土或砂采用夯实或灌水密实，之后采用压路机分层碾压，回填应分层回填及夯实，并应控制每层回填厚度不超过25cm，夯实后采用核子密度仪测量密实度，待其压实率达到95%以上后方可进行下道工序施工。(a)roaddemolitionandrecovery?Municipalwatersupplyanddrainagepipelineconstructioninevitablyinvolvestheremovalofcertainroadandbacktowork,inordertoensureconstructionsafetyandqualityofroadbed,roadexcavationshallbecomputedaccordingtotheconstructiondrawingsbeforeopeningwidth,markedbywhitepaintafterexcavationlinewithcuttingmachinecuttingthepavement,excavatoronthebrokenconcretepavementandgravelcushionlayersuchasexcavationandarrangeforlateruse,aftercompletionoftheconstructionofthepipelinetrenchbackfillworkdirectlyaffectthequalityoftheroadandusefunction,moreshouldpayattentiontotrenchbackfillingqualityespeciallyinplateauarea,thegeneralofbackfillsoilorsandcompactionorirrigationisclose-grained,afterusingrollerlayeredcrush,backfillshouldbestratifiedbackfillandcompact,andshouldcontroleachbackfillthicknessisnotmorethan25cmandcompactnessaremeasuredwithnucleardensitygauge,aftercompactionforthecompactionratereachesmorethan95%oftherearcanconstructionofnextworkingprocedure.（二）公共设施保护?管道沟槽施工应根据土质情况采用支撑以免造成滑坡、塌方，若施工遇到建构筑物基础或电杆、灯杆等应制定防止下沉或变形措施后方可施工，一般应采用钢板桩加固方法；施工地区地下水量丰富则在管道施工过程中往往需要排水，应制定合理措施以保证地面不发生过大沉降而影响周围建构筑物使用安全；在埋有高压线地区内开挖时要求挖掘机不能在其正上方开挖，必要时采用人工开挖；开挖过程中遇到地下管线和各种构筑物应尽量迁移，若不能迁移应人工开挖使其外露之后采取吊托等加固措施。(2)toprotectpublicfacilities?Pipelinetrenchconstructionshouldbeusedaccordingtosoilconditionssoasnottocauselandslidesandlandslides,ifconstructionmeetsthebasicarchitecturalstructuresorpole,lightpole,etcshouldmakemeasurestopreventsinkingdeformationorrearcanconstruction,generalsteelsheetpilereinforcementmethodshouldbeadopted;Constructionisrichinundergroundwaterpipelineconstructionprocessoftenneedtodrainage,shouldformulatereasonablemeasuresinplacetoensurethatthegroundisnottoolargesettlementandbuiltstructuresaroundtheuseofsafe;Itwasburiedthereishightensionlineareaexcavationforexcavatorcannotinitsupperpartexcavation,necessaryuseofartificialexcavation;Encounteredintheexcavationprocessofundergroundpipelineandavarietyofstructuresshouldbemigrated,asfaraspossiblewit...
