12、 46th 温州发电厂二期工程主厂房水泥砂浆楼地面施工 作 业 指 导 书编制人： 审核人：批准人：编制单位：浙江省第二建筑工程公司温电二期项目经理部编制时间：二OOO年五月三十一日 目 录一、工程概况二、施工准备三、施工程序四、作业方法五、产品保护措施六、作业质量保证七、安全文明要求八、环境保护措施九、施工质量检验标准一、工程概况 1主厂房楼地面水泥砂浆面层主要包括汽机房0.000m层,12、3/A4轴的电气检修间；3.800 m层，11a12、1/AB轴的电缆夹层；6.300 m层，311、1319、AB,119、BC轴的汽机房及除氧间楼层；27.800 m层，13、CD轴楼面等。 2水泥

13、砂浆楼地面做法，汽机房电气检修间为：塘渣回填夯实，钢筋砼地坪，30 mm厚1:2水泥砂浆面层；3.800 m层的电缆夹层、6.300 m层的汽机房及除氧间楼层为：现浇钢筋砼楼板基层，30 mm厚1:2水泥砂浆面层；27.800 m层13、CD轴楼面为：钢筋砼现浇楼板，30 mm厚1:2.5水泥砂浆掺5防水剂面层。二、施工准备2.1作业条件2.1.1楼地面的设备、管道应安装结束；接地扁铁应用膨胀螺丝固定牢固，高出楼面面层的扁铁应先将楼面基层砼凿低后再固定，必须保证扁铁面比楼地面低20mm;2.1.2楼层的结构伸缩缝处理：2.1.2.1、6.300 m层1111A轴、4/AB轴间楼板的伸缩缝，板底

14、用“U”型彩板将缝密封；板面缝两侧各增加一块6 mm厚、90 mm宽的悬挑铁板，将缝覆盖一部分，铁板间的空隙缩小到40 mm，然后用膨胀螺丝固定铁板；接着在铁板面安装“V”型彩板，将缝密封；施工面层时留出10 mm宽的伸缩缝。2.1.2.2由于设备运行产生震动，汽机房楼面与汽轮发电机基座、汽动给水泵基础间的缝隙，在缝两边分别安装L304悬挑角钢，角钢间留出15 mm宽的通缝，不密封。2.1.2.3楼层内小于35 mm的结构缝，用泡沫填实（下部与梁底、板底平齐，并用腻子刮平），面层施工时留出10 mm宽的缝隙。2.1.3楼面格栅板四周、孔洞四周用L304的角钢护边（角钢围成的孔洞比格栅板实际长度

15、、宽度大10mm），保证上述部位的水泥砂浆面层不会被损坏；2.1.4楼层孔洞四周的栏杆应安装好，损毁的应调整、修复；2.1.5各楼层的通道应保证畅通；2.1.6施工用水、用电应引到楼层或楼层附近;2.1.7施工前对人货两用电梯、井架进行检查维修，确保材料的垂直运输；2.1.8施工前对搅拌机、运输车辆进行检查维修，确保砂浆的供应及材料的水平运输。2.2劳动力组织木工 3人 泥工 30人普工 15人 机操工 3人电工 3人 机修工 3人驾驶员 3人 23主要机具准备231计量仪器 钢卷尺（HY358） 6把 水准仪（NA2） 1台 塔尺 1把232其它机具靠尺 4根 砂浆搅拌机 2台 人货两用电梯

16、 1座 手拉车 15辆 翻斗车 4辆 井架 1座 铲刀 10把 大型切割机 1台手提式切割机 2台 扫把 6把 24主要材料准备黄砂 500t 水泥（P.O425#） 300吨 钢丝网片 500m2 4钢筋 约1吨 细石子 5吨 异型彩板 400m油膏 400kg 304角钢 500m三、施工程序楼地面基层清理测量标高、做灰饼砂浆面层施工养护切割分格缝水泥砂浆踢脚线、分格缝嵌油膏。四、作业方法4.1楼地面面层施工前，先对基层面进行清理、冲洗，清除表面落地砂浆、油渍、灰尘、杂物等，以防止砼与砂浆接合不严实而起壳、裂缝。42基层清理干净后复核标高，并与对应的建筑高度相比较,基层面过高的部位砼应凿低

17、，基层面过低的部位先用细石砼找平；6.300 m层119、AC轴，由于结构沉降不均引起的汽机房及除氧间楼层的高差，面层施工前除氧间楼板先用C30细石砼找平（表面用木蟹拉毛）。43按照建筑高度用1：1水泥砂浆做灰饼，间距2m，灰饼面用铁抹子抹平。灰饼面标高即为楼地面标高，灰饼应在楼地面面层施工前12天做好，保证灰饼达到一定强度，施工时能真正发挥作用。44在安装设备、管道过程中楼面被凿出的洞，吊模后用与楼板同级配的砼补平。4.5汽机房电气检修间、3.800 m层的电缆夹层、6.300 m层的汽机房及除氧间楼层水泥砂浆面层，水泥与黄砂重量比为1:2；27.800 m层，13、CD轴楼面重量比为1:2

18、.5水泥砂浆掺5防水剂面层。4.6楼地面找平层施工时，浇水湿润基层，然后用水灰比为0.40.5的水泥浆进行扫浆，随扫随铺砂浆，确保找平层与基层，不起壳、空鼓。4.7浇筑时，用铁铲将砂浆向四周分散，先用2m长刮尺按照灰饼的高度将砂浆赶平，再改用短直尺进行二次平整，接下来用木蟹进行压实压平，待砂浆稍微收水后用铁抹子进行二次压光。压光应根据现场效果，必须进行三次、四次光面，确保面层平整、光洁、色泽一致、无抹痕。4.8面层施工后，再做120高水泥砂浆踢脚线。墙面做法为：先用12厚1：3水泥砂浆打底刮糙，再用8厚（出墙厚度）1：2.5水泥砂浆罩面压实赶光；柱直接用8厚1：2.5水泥砂浆罩面压实赶光，踢脚

19、线内的柱线角补平；踢脚线阴阳角均做成直角。4.9楼面洞口的止口(宽100、高150)用相同成份的水泥砂浆抹平压光。4.10楼地面的分格缝，横向按9m（轴线距离）分缝，纵向：汽机房分别在1/A、2/A、3/A、4/A轴的柱边设分格缝（并结合结构缝作适当调整），除氧间在BC轴的跨中设分格缝，煤仓间在CD轴中间设一条分格缝。水泥砂浆面层养护结束后，弹线切割出（结构缝上部的分格缝用嵌木条的方式留设）。4.11大面积上的分格缝用大型切割机割出，切割时在平行于墨线方向摆放一根8槽钢，便于沿着直线方向推拉切割机，以保证割出的缝通直、匀称；楼地面角落及与设备或管道相碰的部位则用手提式切割机割出；分格缝宽5mm

20、，深20mm，用油膏灌满灌实。五、产品保护措施5.1水泥砂浆压光后,施工部位的四周拉警戒线或用脚手片围护,并挂上“禁止通行”的警告牌,24小时内严禁上人。5.2水泥砂浆面层施工后，从第二天开始进行浇水养护七天，每天浇水不少于两次。5.3预先与监理、总包单位联系，由他们协调安装单位，在水泥砂浆面层养护期内，不允许堆放重物（尤其是重型设备、管道），不允许安装设备及管道，以免破坏面层而起砂。5.4养护期过后，堆放设备、管道下部应垫枕木；拖运设备、管道时，楼地面上应铺枕木、轨道、彩布，或用专用手摇车运输设备，以防划伤、磨破水泥砂浆面层。5.5起吊、安装设备、管道时，应缓慢、匀速提升、下降，禁止骤然升降

21、，造成设备、管道碰撞地面，砸破面层。5.6楼地面上搭拆脚手架时，钢管、轧头应稳拿轻放，禁止随意乱扔，砸破面层。5.7板底施工油漆、涂料时，相应的楼地面上应铺上彩布或塑料薄膜,以减少油漆、涂料跌落污染面层；油漆、涂料跌落楼地面，应及时用棉纱、松香水等擦拭洁净。5.8水泥砂浆面层上，严禁拌制砼或砂浆，临时堆放砼或砂浆时，应先铺上塑料薄膜等，施工结束后，及时用水冲洗砼或砂浆堆点。5.9施工过程中跌落楼地面上的砂浆应及时清理干净。六、作业质量保证1.作业前进行质量技术交底。2各种原材料到达施工现场后，必须验证其合格性。3.楼层与墙面交接处增加一层600mm宽三目钢丝网片，埋进墙内、板内各300mm；除

22、氧煤仓间及汽机房框架梁与现浇楼板的接头处，加铺一层4g100双向钢筋网片，网片为框架梁宽加1000mm（梁两侧各500mm），防止这些部位出现裂缝。4由于楼地面的埋件、埋管等引起面层厚度过薄（少于5mm）而出现裂缝，施工面层前在这些部位加铺一层比埋件、埋管每边大100 mm的钢丝网片，并用水泥钉将网片固定在楼地面基层上。5.角钢安装前应逐根挑选，起翘、弯曲的角钢应调整后再使用；安装时拉通线，确保角钢边沿通直、上口平整。6面层的水泥砂浆应采用机械搅拌，且搅拌时间不少于2min，应拌至砂浆色泽均匀为止；砂浆稠度不大于3.5cm。7水泥砂浆面层施工前，先做栏杆四周的止口（止口表面比楼层面高出20mm

23、，以便挡水），伸缩缝处角钢下口的空隙、压型彩板接头处的缝隙都要预先用砂浆堵实，以减少面层施工时水泥浆下漏污染梁侧、板底涂料、钢梁油漆。8施工踢脚线时，应拉通线，确保踢脚线上口平直，出墙厚度一致。9楼层施工后须凿洞或增加留孔的位置、面层有起壳、裂缝的部位，应用切割机割出规则的缝后再开始凿（处理后，再用相同成份的水泥砂浆修补），不允许随便乱凿乱敲，以防引起相邻部位的面层起壳、空鼓。七、安全文明要求1.大力宣传安全第一、预防为主的方针，加强对职工的安全教育，采取有效的安全防护措施，确保安全生产。2.作业现场,用电设备必须一机一闸,并安装触电保护器。3.作业人员应遵守施工现场的所有规章制度。4溅在柱面

24、、墙面及设备上的砂浆应及时清理干净。5.材料做到用多少拉多少，施工垃圾每天下班前都应清理干净，并到指定的地点倾倒，切实抓好现场的文明施工。八、环境保护措施 1. 采用散装的水泥,在入库过程中容器的排气设施须用多层过滤设施,存放过程必须有防护设施，以防止粉尘飞扬，在使用过程中尽量使用螺旋输送器，出料口装上转套筒（麻布等）减缓出料速度，套筒长度以不出现落差为宜；采用袋装的水泥，在搬运、使用过程中必须轻拿轻放，避免高处坠落，尽可能减少落差，不得用力摔打， 存放过程必须有采取防粉尘飞扬措施。 2.露天堆放的易产生粉尘材料（如：黄砂等）在搬运、堆放、使用过程中如过于干燥应适当洒水进行湿润。在用机械作业过

25、程中，作业机械应减小机械动作，尽量减小落差，以减少粉尘的产生。 3砂浆应在容器内适量搅拌，避免剩余。砂浆落地灰应及时回收利用，加适量水泥重新搅拌使用，对确实不能使用的可做道路垫层使用。 4施工过程中产生的建筑垃圾，应收集到一起，到垃圾堆场倾倒或统一在允许回填范围内回填，不允许随处乱倒。 5切割分格缝时，应边撒水边切割，以减小灰尘。 6. 施工现场中，应经常洒水，保持尘土不上扬。在清理打扫作业场地时，应进行洒水湿润。 7.加强设备润滑和维护保养，加强对机动车辆的维护和保养，并严格执行相应作业指导书和设备点检规程，保持技术性能良好。 8.由质安科、材料科组织，不定期的进行检查，对作业班组进行检查，

26、对处置规范的给予适当奖励。反之，则勒令定期整改，并给予一定的经济处罚。 九、施工质量检验标准 项目 质 量 标 准 及 允 许 偏 差 （mm ）检测方法及工具面层的材料、强度（配合比）和密实度必须符合设计要求和有关现行标准（规范）规定观察检查和检查试验报告各层之间的结合必须牢固，无裂纹、空鼓。在一个检查范围内空鼓面积不超过400cm2，且不多于2处观察和小锤轻击检查表面质量洁静，无裂纹、无脱皮和起砂等缺陷观察和尺量检查踢脚线质量高度一致，出墙厚度均匀，与墙面结合牢固，局部空鼓长度不超过200mm，且在一个检查范围内不多于2处小锤轻击、尺量和观察检查表面平整度42m靠尺和楔形塞尺检查踢脚线上口
