4、:、施工前审核图纸。编制防水工程施工方案,(并由地下防水专业施工队编写出详尽的施工工艺)并进行技术交底。地下防水工程必须由专业队施工,操作人员持证上岗。、铺贴防水层的基层及四周80cm高维护墙粉刷必须按设计施工完毕,并经养护后干燥,含水率不大于9%;基层应平整、牢固,不空鼓开裂、不起砂。、防水层施工涂底胶前(冷底子油),应将基层表面清理干净。、施工用材料均为易燃,因而应准备好相应的消防器材。3、施工工艺(1)、工艺流程:基层清理涂刷基层处理剂铺贴附加层热熔铺贴卷材热熔封边做保护层 (2)铺设防水层前,找平层必须干净、干燥。检验干燥程度的方法,可将1M2 卷材干铺在找平层上,静置34小时后掀开,
5、覆盖部位与卷材上未见水印者为合格。检测找平层含水率应小于9%。(3)、基层清理:对桩头超高的部分应进行裁桩到设计高度,进行桩身清理(表面泥土杂物),按设计要求(图纸会审纪要答复)详图将桩边做成斜角。大面积施工前将基层清理干净,并由工长、质检及监理进行验收后方可作业。(4)、涂刷基层处理剂:在基层表面满刷一道用汽油稀释的氯丁橡胶沥青胶粘剂(具体以材料说明和试验定),涂刷应均匀,不透底。(5)、铺贴附加层:管根、阴阳角部位加铺一层卷材。按规范及设计要求将卷材裁成相应的形状进行铺贴。(6)、铺贴卷材:将改性沥青防水卷材按铺贴长度进行裁剪并卷好备用,操作时将已卷好的卷材,用30的管穿入卷心,卷材端头比
6、齐开始铺的起点,点燃汽油喷灯火专用火焰喷枪,加热基层与卷材交接处,喷枪距加热面保持300mm左右的距离,往返喷靠、观察当卷材的沥青刚刚熔化时,手扶管新两端向前缓缓滚动铺设,要求用力均匀、不窝气,铺设压边宽度应掌握好,满贴法搭接宽度为80mm。条粘法搭接宽度为100mm。(7)、热熔封边:卷材搭接缝处用喷枪加热,压合至边缘挤出沥青粘牢。卷材末端收头用橡胶沥青嵌缝膏嵌固填实。 搭接缝熔焊粘结示意(8)、保护层施工:平面做水泥砂浆或细石混凝土保护层;立面防水层施工完,应及时稀撒石渣后抹水泥砂浆保护层。4、质量标准(1)、保证项目、高聚物改性沥青防水卷材和胶粘剂的规格、性能、配合比必须按设计和有关标准
7、采用,应有合格的出场证明。、卷材防水层特殊部位的细部做法,必须符合设计要求和施工及验收规范的规定。、防水层严禁有破损和渗漏现象。、工长、质检对作业过程质量进行有效控制。(2)、基本项目:、基层应平整,无空鼓、起砂,阴阳角应呈圆弧形或钝角。、改性沥青胶粘剂涂刷应均匀,不得有漏刷、透底和麻点等现象。、卷材防水铺附加层的宽度应符合规范要求;分层的接头搭交接宽度应符合规范的规定,收头应嵌牢固。、卷材粘接应牢固,无空鼓、损伤、滑移翘边、起泡、皱折等缺陷。5、成品保护(1)、地下卷材防水层部位预埋的管道,在施工中不得碰损和堵塞杂物。(2)、卷材防水层铺贴完成后,应及时做好保护层,防止结构施工碰损防水层;外
