9.施工工序和施工方法Constructionprocedureandplans
9.1施工工序Constructionprocedure
除氧器支架基础施工工序为:
测量放线(土方开挖边线)→土方开挖→垫层施工→测量放线(轴线定位,模板边线)→基础钢筋、柱头预埋钢筋绑扎→模板支设、加固→质量验收→砼浇灌、养护→拆模清理→测量放线(中心线、标高)→柱头钢筋绑扎→模板支设、加固→质量验收→砼浇灌、养护→拆模清理→测量放线(中心线、标高)整体验收→土方回填

9.2施工方法Constructionplans
9.2.1土方开挖及回填Excavationandbackfill
土方开挖及回填要求见现场开挖及回填Siteexcavationandbackfill(PR-8710-8100-0013)
9.2.2垫层施工Cushioningconstruction
清基完成经验收合格后,进行垫层施工,可用5×10cm枋木或模板支好侧模,木枋接头处固定,防止混凝土浇注时偏位。
用水准仪打上标高线,垫层浇砼时必须压实、压平。

9.2.3测量放线Measuringandmarking
施工前将垫层顶部清理干净,由测量人员组织木工在垫层上放出各中轴线及基础各中心线,红油漆涂三角符号标志,经复核无误后交验收。
中轴线及基础中心线经复核验收后,木工人员根据各基础中心线分别将基础模板边线(模板内边线)、上部柱段模板边线及预留孔等部位边线用墨线弹出,必要时四角用红油漆三角符号标志,经复核无误后方可进行模板施工。

9.2.4模板工程Formworkengineering
除氧器支架模板均采用1220×2440标准镜光面胶合板,模板表面应干净,无污渍及缺棱掉角现象。
模板相互拼装时在拼缝内侧封贴封箱带,防止拼缝处漏浆,影响砼质量。
模板(包括支撑)应根据具体要求画出几何图形以便支模时能保证他们正确的位置、形状及横断面,从而使得最终的砼构件能够在允许的尺寸偏差之内。
施工时在地面预先按设计尺寸进行组合,与设计尺寸不符时按设计尺寸进行切割,要求断面整齐,校核无误后再进行组合安装。
重复使用的模板要求进行编号。
模板缝采用封箱纸封堵。
模板安装前应涂刷隔离剂,应涂刷均匀。
涂刷后应由专人检查,避免局部漏刷,影响砼表面观感。

支撑系统用直径48mm、长3.5m钢管搭设脚手架。
模板支撑要求具有足够的强度、刚度和稳定性。
固定模板用背枋净空尺寸为150mm。
柱模横向钢管,从垫层上100mm布置第一道横钢管,然后间距500mm一道,最后一道离上口不得超过100mm。
支模后,模板几何尺寸应减少5mm,以减少混凝土胀模对混凝土尺寸的影响。
