27、）基层处理：将粘在基层上的灰尘清扫干净，最后用清水将基层冲洗干净。清洗完毕后先自检后再报项目部（栋号长或质检员）验收，经同意后方可进行下道工序。另应注意在清洗过程中水的流向是否合适。4）找标高、弹面层水平线：先对墙体现有的平水线复核，再根据平水线量测出楼面面层的水平线（楼面面层水平线高于楼面结构标高50mm）弹在四周墙面上。5）洒水湿润：在抹面层之前一天，对基层表面进行洒水湿润。6）水电线管保护层施工：水电线管保护层采用比楼面高1 标号的微膨胀细石混凝土。7）满铺钢丝网：对线管预埋处铺设钢丝网，钢丝直径 2mm,网格20 mmX20mm, 钢丝网搭接长度不得小于20cm,钢丝网铺设边缘在线管区

28、域30cm以外。8）抹灰饼：根据已弹出的面层水平标高线，横竖拉线，用与细石混凝土相同配合比的拌合料抹灰饼，横竖间距1.5m，灰饼上标高就是面层标高。在细石混凝土铺设完成过程中要随机将灰饼撤走。抹标筋：面积较大的房间为保证房间地面平整度，还要做标筋（或叫冲筋），以做好的灰饼为标准抹条形标筋，用刮尺刮平，作为浇筑细石混凝土面层厚度的标准。刷素水泥浆结合层：在铺设细石混凝土面层之前，在已湿润的基层上刷一道 1:0.40.5（水泥:水）的素水泥浆，不要刷的面积过大，要随刷随铺细石混凝土，避免时间 过长水泥浆风干导致面层空鼓。9）浇筑细石混凝土：细石混凝土搅拌：细石混凝土的碎搅拌应依据试验室根据原材料情

29、况计算出的配 合比，应用搅拌机进行搅拌均匀，坍落度不宜大于 30mm,并按国家标准混凝土结构 工程施工及验收规范GB50204-2002 的规定制作混凝土试块，每一层建筑地面工程不应少于两组。ctivities,compre hensive andtamping SafetyFoundation .Troubl eshooti ng, manageme ntmechanism,give fullplaytoroleoftechnicalsupervisionandrealizati on oftroubleshooting,management,improved process managem

46、间内往外退着走）o8） 抹面层、压光：当面层灰面吸水后，用木抹子用力搓打、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。第一遍抹压：用铁抹子轻轻抹压一遍，直到出浆为止。第二遍抹压：当面层砂浆初凝后，踩上面层有脚印但不下陷时，用铁抹子顺着同 一方向进行第二遍抹压，把凹坑、砂眼填实抹平，注意不得漏压。因业主要求地面面层 最后为毛面，为施工地砖等预留条件，故等二遍抹压收光后要用细笞帚将光面拉毛，拉 毛时要注意纹理通顺.9）养护：面层抹压完24h后进行浇水养护，每天不少于 2次，养护时间一般至少 不少于7d（房间应封闭养护，期间禁止进入）。4 .质量保证体系4.1. 质量标准1）水

54、过大、抹压遍数不够、养护期间过早进行其他工序操作，都易造成起砂现象。在抹压过程中撒干水泥面（应撒水泥砂拌合料）不均匀，有厚有簿，表面形成一层厚簿不匀的水泥层，未与混凝土很好的结合，会造成 面层起皮。如果面层有泌水现象，要立即撒水泥砂（1:1=水泥:砂）干拌合料，撒均匀、薄厚一致木抹子搓压时要用力，使面层与混凝土紧密结合成整体。5.2. 面层空鼓、有裂缝由于铺细石混凝土之前基层不干净，如有水泥浆皮及油污，或刷水泥浆结合层时面 积过大用扫帚扫、甩浆等都易导致面层空鼓。由于混凝土的坍落度过大滚压后水分过多， 撒干拌合料后终凝前尚未完成抹压工序，造成面层结构不紧密易开裂。civt , ada on.
