某施工单位承建一南方沿海城市的大型体育馆机电安装工程。合同工期为10个月,于2009年11月10日开工,2010年9月10日竣工。
该工程特点是各类动力设备包括冷冻机组、水泵、集中空调机组、变配电装置等,均布置在有通风设施和排水设施的地下室。
由于南方沿海空气湿度高、昼夜温差大,夏天地下室结露严重,给焊接、电气调试、油漆、保温等作业的施工质量控制带来困难。
通风与空调系统的风管设计工作压力为1000Pa。项目部决定风管及部件在场外加工。
项目部制定的施工进度计划中,施工高峰期在6~8月,正值高温季节。根据地下室的气候条件和比赛大厅高空作业多的特点,需制订针对性施工技术措施,编制质检计划和重点部位的质量预控方案等,使工程施工顺利进行,确保工程质量。
在施工过程中,由于个别班组抢工期,在管理上出现工序质量失控,致使在试车阶段发生施工质量问题,如通风与空调系统进行单机和联动试车时,有两台风机出现震动大、噪声大,电动机端部发热等异常现象。经调查发现:风机的钢垫铁有移位和松动;电动机与风机的联轴器同轴度超差。

为保证地下室管道焊接质量,针对环境条件编制质量预控方案。

答案

参考答案:为保证地下室管道焊接质量,针对环境条件编制质量预控方案:
(1)地下室管道焊接质量预控方案;
(2)工序名称:焊接工序;
(3)可能出现的质量问题:产生气孔、夹渣等质量缺陷;
(4)提出质量预控措施:焊工备带焊条保温筒、施焊前对焊口进行清理和烘干。
