1、住宅工程质量常见问题专项治理技术措施管理措施：1.公司严格按照工程建设施工企业质量管理标准GB50430的规定，建立健全企业质量保证体系，建立企业内部质量监督检查和考核机制，对企业所承揽的各项工程项目的施工进行全过程的质量管理。2.按照关于在全市住宅工程建设中推行样板施工作业方法的通知文件要求，工程开工时，每个工程都要在施工现场制作样板间或样板示范区，以施工样板引路，指导施工作业人员严格按标准化实施作业。3.对易发生常见问题的分项工程、关键工序和关键部位，各项目技术负责人要对施工人员进行技术交底；现场质量检查员应加强施工过程的质量检查，不符合要求的检验批、分项工程不得验收和进入下道工序施工。4

2、.认真做好检验批、分项、分部工程验收工作。严格材料进场的质量验收，不符合设计和产品标准要求的材料严禁使用到工程上。特别要加强工序与工序之间检验批的质量验收，保证分项、分部工程到达合格标准。在工程施工中，严格执行工程质量常见问题防治技术措施，使工程质量常见问题得到有效的治理。技术措施：根据工程施工特点，编制工程质量常见问题预防技术措施：一、屋面渗漏原因分析：1.保温层厚度不够，找平层水泥砂浆配比不准确，强度不足找平层压光不实，养护不好，面层酥松、起砂、起皮等。2.找平层不做界格，不留通气道、通气口。3.屋面坡度小特别是女儿墙根部、天沟和泄水口处。4.突出屋面的烟囱、管道、上人孔、变形缝、高低跨处

3、、女儿墙根部弧度不好，泛水高度不够，防水卷材封口不好。5.部分工程女儿墙、高低跨处仍采用留挑檐泛水老做法。6.屋面防水层厚度不够。预防措施：1.所用原材料应符合国家规定标准和施工标准要求。2.保温层厚度必须符合设计要求，假设设计无要求时，保温层最薄处女儿墙部位、泄水口部位不能小于100mm，应用块状保温材料，不允许用现场珍珠岩的做法。3.找平层水泥砂浆要严格控制水泥用量，水泥与砂的比例不能大于 13,找平层要适时压实、压光，并及时养护，养护时要有保湿措施，抹找平层时要留置分格缝，缝宽为20mm，分格缝间做排气道时宜为30-40mm，排气道间距为6m纵横设置，相互文档编码:CZ2D4K10R6F

27、土的坍落度过大滚压后面层水分过多，终凝前尚未完成抹压工序，造成面层结构不紧而开裂。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，使面层到达结合紧密。3.由于水泥标号不够或使用过期水泥、水灰比过大抹压遍数不够、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，有厚有薄，外表形成一层厚薄不匀的水泥层，未与混凝土很好的结合，会造成面层起皮。文档编码:CZ2D4K10R6F5 HT1U8Y8E1Z1 ZE7Q7S8H8S4文档编码:CZ2D4K10R6F5 HT1U8Y8E1Z1 ZE7Q7S8H8S4文档编码:CZ2D
