大体积混凝土浇筑示意图电梯基坑局部较低的部位，应在浇筑开始时候就首先将电梯基坑底板混凝土浇筑，在底板混凝土能够承受上层混凝土的重量，浇筑上层混凝土时不至外溢时再浇筑上层混凝土，浇筑上层混凝土的时间由现场值班人员和混凝土带班工长视混凝土的凝结的速度确定。适时浇筑上层混凝土，既方便现场作业，又不会在横纵交接处形成施工缝。目前的气候条件，混凝土浇筑的间歇时间控制在3小时内。结合现场的实际情况和混凝土泵的工作效率，按每台泵每小时泵送量30-40m3计算。基础混凝土每个工作面的宽度可定在8-10m之间，在每个工作面内，浇筑完下层混凝土应返回头浇筑上层混凝土。电梯井基坑侧墙混凝土较厚，浇筑侧墙混凝土的分层高度不得大于300mm，并要循环浇筑，适当间歇，必要时可采用塔吊吊运浇筑。基础承台、基础梁和防水板相交的吊模处浇筑混凝土的方法与上述部位类似。浇筑上层混凝土时，振捣棒插入下层混凝土5-10cm，以消除上下层混凝土间的缝隙和下层混凝土表面的泌水。混凝土浇筑过程中，看模板的工人要随时观察模板和支架的稳定情况，模板和支架发生变形时，要及时停止浇筑，重新加固好以后再继续浇筑。混凝土表面在混凝土初凝前用工具抹压一次，随即覆盖一层塑料薄膜和二层麻袋保温保湿。承台和基础的侧面也采用麻袋包裹的方法进行保温。3、基础混凝土计划开始浇筑时间2006年8月8日8:00，在正常浇筑情况下，按平均每小时浇筑60-80m3计算，本次浇筑时间约需32h，预计在2006年8月9日中午结束。五、大体积混凝土的养护施工时要严格控制大体积混凝土的内外温差，对浇筑后的混凝土进行保温养护，采取保温养护的同时拌有保湿养护。基础保温材料采用塑料薄膜和麻袋，覆盖一层塑料薄膜、二层麻袋。保温层覆盖时交叉覆盖，让其自身湿养护，底板侧面采用砖模保温养护，在实际测温过程中如出现内外温差超过25℃时，适当加盖保温材料，防止混凝土产生温差应力和裂缝。一般砼浇注完成第三、四天为升温的高峰，其后逐渐降温。保温材料宜10天以上为妥，降温速度不易过快，以防温差应力产生裂缝。由于砼在温降中产生的拉应力较大，所以在浇筑完4d内应及时测量放线，4dcandidateYaoHuafengadvancedlearningactivities,guidingalltheofficersandmentoadvancedmodelsasamirror,setupthededication,self-discipline,andprotectthespiritofpeace,clarifyambiguousideas,distinguishthemerits.Third,playculture.Enactmentofthehonestandcleangovernmentculturalconstructionguidelines,tips,theindependentCommissionagainstcorruptionculturethroughculturalprogrammeschuangyan,startyourownhonestbookcorner,dispensingofficesuppliesoftheICAC,dissatisfiedwiththemicro-languageactivitiessuchastheindependentCommissionagainstcorruption,createdarichatmosphereoftheindependentCommissionagainstcorruptioninthearmy.InparticulartheGroupreliesonstrongregionalcharacteristicsandculturalorganizations,createafloorareagroup"concerncultureandmusiccultureand",pingjiangBrigadeof"redculture",linxiangBrigade"independentCommissionagainstcorruptionwarningeducationPavilion"cultureasafeatureoftherepresentativesystem,maketheconsciousnessoftheindependentCommissionagainstcorruptionintothethinkingofofficersandmenandblood.　　Inparticular,thisyearinApril,July,jointborderdetachment,guard,pingjiangwascarriedoutin"carryforwardthespiritoftheheroes,becomealoyalguard"qingmingtombsweepingandrevolutionarymartyrs"heritageredgene,vyingforfoursoldiers"event,there-LiverpoolRoad,feelingthattorneventfulyears,tocastpolicesoul,enhanceeffectivenessofischemic,forceshasarousedstrong
