2、筒和砼试模排放在施工浇筑现场。3、模板支设完毕,并做好预检。4、防水卷材表面铺设一层塑料布隔离层,塑料布接缝搭接宽度为100mm。5、砼标高控制灰饼已做完,间距为1.5m。6、防水层表面的卷材头,包装纸等清理干净。7、为防止砼浇筑过程中因冲击力过大损伤卷材,涂膜上部覆盖双层彩条布覆盖,边浇筑边撤掉覆盖。三、施工工艺:工艺流程:混凝土进场混凝土检测混凝土出料混凝土泵送混凝土振捣混凝土找平压光混凝土扫毛洒水养护1、防水保护层采用商品细石混凝土进行施工,细石混凝土强度等级为C20,厚度为50mm,电梯基坑、集水坑、后浇带等有高差的部位,应100100mm木方支模栏挡,并用50100的木方上下支撑,固
3、定牢固,浇筑时先浇筑平面,待平面砼终凝后再抹斜面砼。2、混凝土进场后进行坍落度和温度的检测,坍落度要求为140-160mm,否则将其退场不准使用。3、混凝土浇筑采用汽车输送泵进行施工,由西向东进行施工。4、专人操作汽车输送泵,别人不得随意乱开,使用前先将泵机和泵管注水润湿,然后再进行使用。泵送时泵机手和信号工必须配合好。5、混凝土随泵送随摊开,摊开后用平板振动器振捣,振捣以混凝土泛浆和不冒气泡为准,应避免漏振,欠振和过振,再用刮杠按已做好的灰饼标高控制点找平。6、找平后立即用木抹子搓平,并随时用2m靠尺检查其平整度。7、木抹子抹平后,立即用铁抹子压第一遍,直到出浆为止。8、面层砂浆初凝后,上人
4、稍有脚印并不下陷时用铁抹子压第二偏,边抹压边把凹处填平,要求不得漏压,随压光随用小条帚平行扫毛,扫毛的纹条要顺直。9、养护:混凝土终凝后,必须洒水养护,养护时间不少于7天,每天不少于3遍,以保持面层湿润为宜。10、做法详图导墙保护层做法:首先用抗裂砂浆在防水表面拉毛养护到位,再用1:2的水泥砂浆抹灰施工,12小时后浇水养护。四、质量控制:1、商品砼的配合比、原材质量、搅拌、运输、养护和施工符合施工规定和有关规定; 2、砼试块的取样、制作、养护和实验必须符合施工规范的规定; 3、砼摊匀压实,无蜂窝、孔洞等现象; 4、砼垫层厚薄均匀,无厚薄不均、凹凸不平,下陷断裂等现象,表面找平层必须坚固,无松动
5、、起鼓、起砂等现象。 5、在地坑、排水沟等有坡度地方一定严格控制,防止倒坡、积水;绑扎钢筋前基层必须经过严格检查验收。 6、基层表面应平整。用2m长的直尺检查时,直尺与基层表面间的空隙不应超过5mm,空隙只允许平缓变化,且每米长度内不得超过一处。若表面高低不平或凹坑较大时,应用1:2的水泥砂浆抹平。 7、基层表面的阴阳角处、凸出表面的部位均应作出设计角度,棱角顺直在一条直线上。 8、垫层砼允许偏差 表面平整度:5mm,用2米靠尺和楔形塞尺检查; 标高:10mm,用水平仪检查; 坡度:不大于30mm,用坡度尺检查; 厚度:在个别地方不大于设计厚度的1/10mm,用尺量检查。 五、成品保护1、在已
6、浇筑的砼强度达到5Mpa以上才允许在上行走或进行下一道工序施工; 2、在基础混凝土垫层浇筑时,随时作好对防水层的保护,小推车腿要用软材料包好,运料车道要铺一层彩条布,再铺脚手板,卸料时要轻放,避免破坏防水层。 3、注意避免尖锐施工机具对防水层的破坏。六、文明安全施工:1、施工人员必须戴好安全帽,系好下颚带。2、施工现场严禁吸烟,严禁大声喧闹。3、夜间施工应有充分的照明。4、电梯坑、集水坑内施工需登高作业时,应有人监护或采取其它安全措施。5、施工用电要找电工,严禁私自乱接。6、汽车输送泵管下不得站人,要有专人扶好橡胶泵管,防止泵管晃动伤人。审核人交底人接受交底人1、本表由施工单位填写,交底单位与
