某大学本科生毕业论文PAGEIV剑阁县高池乡卫生院业务楼冬季专项施工方案摘要：剑阁县属于亚热带湿润季风气候,同时受海洋,大陆性气候控制。特点明显,其特征是冬季漫长寒冷,春季干燥多风,夏季炎热多雨,秋季凉爽湿润,春季季短,冬夏季长。以剑阁历年气象资料看:历年平均气温为15～16摄氏度,七月平均气温29.9摄氏度,1月平均气温2.3摄氏度,极端最高气温36.1摄氏度,极端最低气温-1.1摄氏度。冬季施工期限划分原则:当室外温度连续五天平均低于5℃,即进入冬季施工,当室外温度连续5天高于5℃即解除冬季施工，拟采用暖棚法进行冬季砼施工。混凝土的冬期施工,主要是保证混凝土在浇筑时不冻结,能顺利浇筑在模板范围之内时,应进行混凝土的覆盖保温养护。低温条件下使用的钢筋,施工过程中加强检验,检查;钢筋在运输和加工的过程中防止撞击和刻痕。采用木板作为模板时,在木模板的区格间填以50mm厚保温棉,用胶粘贴在模板上,浇墙体混凝土时,外墙外侧模板应再覆盖一层石棉保温。加强冬季劳动保护安全工作,冬期要作好防滑,防冻,防煤气中毒等工作。脚手架,上下梯道要采取防滑措施，雪霜天气要及时清扫，大雪后及时检查脚手架,防止空中坠落事故发生。关键词：冬季施工；安全；措施；预案JianGeXiankochitownshiphealthhospitalbusinessbuildingwinterspecialconstructionschemeAbstract:JianGeXianasubtropicalhumidmonsoonclimate,andsea,continentalclimatecontrol.Characteristicssignificantly,itscharacteristicislongandcoldwinter,dryandwindyspring,hotandrainysummer,theautumncool,humid,thespringseasonisshort,summerlongwinter.ToJianGehistoricalmeteorologicaldatatosee:theaveragetemperatureof15~16degreesCelsius,Julymeantemperature29.9degreesCelsius,Januaryaveragetemperatureof2.3degreesCelsius,extrememaximumtemperature36.1degreesCelsius,extrememinimumtemperaturesto1.1degreesCelsius.Winterconstructionperioddivisionprinciple:whenoutdoortemperatureforfiveconsecutivedaysonaveragelessthan5℃,namelyintothewinterconstruction,whenoutdoortemperatureishigherthan5℃for5daysorremovewinterconstruction,proposedUSESthegreenhousesinwinterconcreteconstruction.Concretewinterconstruction,themainistoensurewhenpouringconcretedoesnotfreeze,smoothcastingintherangeoftemplate,shouldbecoveredwiththermalinsulationofconcretecuring.Lowtemperatureundertheconditionofusingsteel,constructionprocesstostrengtheninspection,inspection;Steelintheprocessoftransportandprocessingtopreventbumpandnotch.Usingwoodasatemplate,betweentheareaofwoodtemplatetofillina50mmthickinsulationcotton,usegluetostickonthetemplate,pouringconcretewall,outerwalllateraltemplateshouldbecoveredalayerofasbestosinsulation.Strengthenlaborsecurityworkinwinter,thewinterperiodtomakegoodanti-skid,antifreeze,g
