基层处理：先将灰尘清扫干净，然后将粘在基层上的垃圾铲掉，（如有油污污染地面，需用碱水将其刷掉，最后用清水将基层冲洗干净）。7.2 抹灰饼、放钢筋网片：按照墙、柱面上弹出+100cm水平标高线，测量出地面面层的水平线，弹在四周墙、柱面上。用与细石混凝土相同配合比的拌合料抹灰饼，横竖间距1.52.m，灰饼上标高就是找坡层面层标高。7.3 浇筑细石混凝土7.3.1 地面细石混凝土浇筑：将搅拌好的细石混凝土浇筑到地面基层上，紧接着用 2m长刮杠顺着灰饼刮平，如有凹处及时用混凝土填平；用平板振荡器进行振捣。7.3.2 抹面层：细石混凝土初凝后，撒一层干拌水泥砂(1：1=水泥：砂)拌合料揭面，撒匀再用2m长刮杠刮平，(操作时均要由内往外退着走)。当面层灰面吸水后，用铁抹子抹平，将干水泥砂拌合料与细石混凝土的浆混合，使面层达到结合紧密。7.3.3 骨料：a:为确保地面工程质量每天浇注混凝土的面积不得大于1500平M。b:混凝土强度不得小于C25不得加早强剂。有良好的和易性，混凝土表面能起浆，为减少泌水，应严格控制混凝土水灰比（不高于0.5）和坍落度（不大于14cm）。振捣棒充分振捣，确保混凝土密实，用钢磙等压平。由于耐磨层的厚度只有 1.5 2.5mm，所以耐磨地面的平整度取决于混凝土的平整度。缩水后的文档编码:CV3V2P3G2C8

痕迹且表面无明水时，进行下步工序。根据施工面积计算好用量，每平M5kg耐磨骨料,将规定用量耐磨材料，按先边角、阳光直晒和风口部位，再由前往后依次均匀铺撒于混凝土面层。铺撒耐磨材料时施工人员应穿软质平底鞋。当耐磨材料吸收混凝土中水分返潮时，用抹光机压实。边角、阳光直晒和风口部位的混凝土面层水分蒸发快，易干燥、硬化，应先用塑料抹子搓平提浆，再用铁抹子压光。大面积施工则采用抹光机，由前往后、左右往复充分压实。当混凝土面层已干燥则必须立即用抹光机对其强行提浆（同时可少量洒些水），稍事后用抹光机往复压实。7.4 养护：面层抹压完24h 后进行浇水养护，每天浇水2 次。7.5 分仓缝放线：在混凝土浇筑终凝以后可以进行分仓缝放线，按44m间距弹线，在柱中线留设缝深30mm、宽 5mm 的分仓缝，柱与柱间留设缝深30mm、宽 5mm 的分仓缝，并在柱四周距柱100mm 留设缝深 30mm、宽 5mm 的分仓缝，全部用填缝剂填充。7.6 机械切割分仓缝：面层完工3 天左右应及时进行切缝处理，以防止混凝土裂缝的产生。按设计要求在地面弹出分格线，调整切缝机切割深度，按分割线标志进行切割。对墙根，柱根等部位切割不到的部位以及顶头缝部位，改用云石机切割。7.7 分仓缝内嵌油膏，嵌油膏前必须用气泵对分仓缝进行清理，清理干净以后方可以嵌油膏。7.8 质量验收标准文档编码:CV3V2P3G2C8 HN10U4H6N9L6

基本工程：面层表面洁净，无裂纹、脱皮、麻面和起砂等现象。地沟坡度符合设计要求，沟内无积水、保证水能够流入集水坑内。7.8.3 允许偏差工程：表面平整度 5，用 2m靠尺和楔形塞尺检查。8、注意事项8.1 在操作过程中，注意运灰双轮车不得碰坏门框及铺设在基层的各种管线。8.2 面涂养护：面涂施工完成后所有进入地下车库的通道要全部封闭，并在通道口挂上明显“禁止入内”的标志牌，同时施工方安排专人值班看管，三天内禁止上人，7 天以内不可与水、酸、碱等化学物品接触，若不慎沾涂，应立刻用干布擦干净。8.3 面层养护时间符合要求可以上人操作时，防止硬器划伤地面。8.4 基层混凝土必须振捣密实，并用刮扛找平至地面水平标高。8.5 分隔缝的切割应在耐磨地面施工完23 天内进行，太早易对地面造成损坏，太晚则混凝土已产生裂缝。8.6 每道工序严格进行自检和复检，不合格不进行下道工序。8.7 对工人进行施工前的技术培训和安全教育，严格遵守施工现场的各项规定。与甲方、监理人员保持密切合作。8.8 严格控制电器开关，由专人负责看管。文档编码:CV3V2P3G2C8 HN10U4H6N9L6 ZF10I7X6F2N5文档编码:CV3V2P3G2C8

基层清理不彻底、不认真：在抹水泥砂浆之前必须将基层上的粘结物、灰尘、油污彻底处理干净，并认真进行清洗湿润，这是保证面层与基层结合牢固、防止空鼓裂缝的一道关键性工序，如果不仔细认真清除，使面层与基层之间形成一层隔离层，致使上下结合不牢，就会造成面层空鼓裂缝。9.1.2 涂刷水泥浆结合层不符合要求：在已处理洁净的基层上刷一遍水泥浆，目的是要增强面层与基层的粘结力，因此这是一项重要的工序，涂刷水泥浆调度要适宜(一般 0.4 0.5 的水灰比)，涂刷时要均匀不得漏刷，面积不要过大，砂浆铺多少刷多少。一般往往是先涂刷一大片，而铺砂浆速度较慢，已刷上去的水泥浆很快干燥，这样不但不起粘结作用，相反起到隔离作用。9.2 地面起砂9.2.1 养护时间不够，过早上人：水泥硬化初期，在水中或潮湿环境中养护，能使水泥颗粒充分水化，提高水泥砂浆面层强度。如果在养护时间短强度很低的情况下，过早上人使用，就会对刚刚硬化的表面层造成损伤和破坏，致使面层起砂、出现麻坑。因此，水泥地面完工后，养护工作的好坏对地面质量的影响很大，必须要重视，当面层抗压强度达5MPa时才能上人操作。9.2.2 使用过期、标号不够的水泥、水泥砂浆搅拌不均匀、操作过程中抹压遍数不够等，都是造成起砂现象。9.3 面层不光、有抹纹：必须认真按前面所述的操作工艺要求，用铁抹子抹压的遍数去操作，最后在水泥终凝前用力抹压不得漏压，直到将前遍的抹纹压平、压光为止。文档编码:CV3V2P3G2C8 HN10U4H6N9L6 ZF10I7X6F2N5文档编码:CV3V2P3G2C8 HN10U4H6N9L6
