14、施工人员已接受交底(安全、技术)。四施工要点溢流池分一次施工,预埋铁件固定好后一次施工到顶。施工工序:定位放线垫层支模垫层砼二次放线验收脚手架搭设(底板钢筋临时支撑)绑扎底板钢筋和池壁钢筋放置铁件验收(W点)模板支设加固验收砼浇筑养护拆模4.1主要施工措施4.1.1根据溢流池设计坐标A=950.97,B=758.2,测量人员冲出K3、1/23线作为施工放线基准线,现场施工人员根据需要翻设其他施工用线。4.1.2砼垫层施工,按3.0布置一标高控制点(30钢筋头),收面木夯搓两遍,钢抹一遍,拍实收平。4.2钢筋工程4.2.1钢筋严格按图放样,放样单必须经钢筋加工车间技术员复核,并确认无误后交付配制
15、,并统一挂牌。4.2.2采用250型,180型拖拉机运输钢筋,钢筋运输人员在现场按尺寸、型号分别归类堆放整齐。4.2.3绑扎前,仔细核对成品料的规格、数量、形状是否与图纸相符,以免引起返工。钢筋绑扎,严格按图纸设计及规范要求执行,画线排列,接头按要求错开,在同一截面,不能大于50%。4.2.4网片筋交叉处,全部绑扎。绑扎完毕后,要进行隐蔽工程验收,签字后,方可进入下道工序。溢流池底部钢筋保护层用505040的同强度等级砼垫块(间距约1.51.5)垫设。4.2.5底板面层钢筋施工前,先搭设钢管临时支撑架,绑扎完成后,用25马凳撑筋支撑面筋,每2.0一个,经验收合格后,方可拆除原临时钢管支撑。4.
16、2.6雨过天晴后,钢筋绑扎前必须将钢筋上的干硬泥块和污垢用钢刷刷尽,清理干净后方可绑扎。4.2.7钢筋负温焊接,采用电弧焊满焊,当环境湿度底于-20时,不宜施焊。4.2.8负温电弧焊焊接电流应微弱增大,焊接速度适当减慢。在焊接过程中,一般应采用短弧施焊,防止断弧,且不要产生烧伤现象和非焊接部位引弧。4.3模板工程4.3.1模板安装前,复查垫层标高。4.3.2模板安装前仔细选模,将模板面清理干净,并刷油。4.3.3模板采用多层板加木背档工艺,加固采用地锚支撑及钢管背楞,每隔1.2m设钢管锚固桩,抛撑间距1.2m,斜撑间距900mm。为防止板墙胀模,设对拉螺杆,拉杆间距600mm或900mm。(见
17、附图)4.3.4预埋铁件用钢管固定于架管上,位置标高核实无误方可封模固定。4.4脚手架工程脚手架采用双排脚手架,第一排立杆距池壁300mm,立杆间距1.5米,步距1.5米。4.5砼工程4.5.1砼浇筑前检查模板加固是否牢固可靠(包括扣件是否松动、支撑是否合理、地锚是否牢靠),模板内是否清理干净4.5.2砼由搅拌站集中拌制,2台罐车运输,一台泵车浇筑。泵车由西向东依次分层浇筑(行车路线见附图),分层浇筑厚度不大于500。上层砼在下层砼初凝前浇筑,间隔时间控制在1-1.5h内。4.5.3砼浇注前必须清除模板和钢筋上的污垢,浇筑时尽量加快砼的浇筑速度,防止热量散失过多。4.5.4严格控制砼的入模温度
18、,使其入模温度不得低于5。4.5.5砼振捣要求插点均匀布置,插点间距不大于400“快插慢拔”,振动棒按交错式振捣,上层振捣必须至少插入下层砼50-100。适当延长振捣时间510s,以增加砼的密实度,改善砼的内部结构。收面时用砼木夯搓两遍拍实抹平,初凝前,钢抹两遍压光(12小时左右)。砼终凝后,对砼及时养护,养护时在砼面铺二层塑料薄膜,加盖两层麻袋片进行保温养护,养护时间不得少于14天4.5.6砼模板拆除前砼强度不得低于砼强度标准值的30。4.5.4一次施工至溢流池顶。4.6防腐及防水工程砼F150、W6,铁件刷防腐漆,水池槽内壁做防腐处理,具体做法装饰工程定。五质量保证及质量通病预防措施:5.
19、1 建立质量保证体系,增强全员质量意识。5.2 坚决执行“四级”验收制度(自检,队级检查,项目部级,监理)上道工序不合格不准进入下道工序。5.3 钢材质证必须齐全,并经现场验证后方可使用。5.4 砼搅拌、运输、浇筑机械要有专人负责调度。5.5 砼浇筑严格按交底执行,并设专人负责实行旁站制。所有的埋件、预留孔洞必须逐个检查记录,固定措施要牢靠,浇筑过程中专人监看。5.6 试验室应现场密切配合,根据现场做的塌落度试验及时调整配合比,并按规范留设试块。未经试验人员同意,任何人不得以任何理由随意加水,一经发现严重处罚。5.7 砼浇筑后要及时抹面,二次抹压收光,并及时养护。养护设专人负责。5.8 砼浇筑
20、前,模板下口用砂浆堵严。5.9 拼模所加木料要刨平刨直,在木料上穿孔,用12螺栓与模板固定牢固。5.10劳动力计划序号工种人数(人)备注1木工252钢筋工153砼工54架子工105小机工36电火焊工27技术员1合计:61人5.11质量控制程序 工序施工完毕 返 工 或 翻 修 合格 施工班组自检 合格施工队复检 合格 项目经理部专检合格通知监理工程师合格 不合格监理工程师检查合格签署质检合格意见合格 进入下到工序512质量标准模板安装允许偏差项目允许偏差()检验方法轴线位移5钢尺检查截面尺寸45钢尺检查垂直度6吊线,钢尺检查相邻板面高低差2钢尺检查表面平整度(2米以上)52米靠尺和塞尺检查预留
