PE 自来水管立管安装不稳:固定施工的 4 个问题解决

2025-09-26

在建筑给排水工程里,PE自来水管的应用愈发广泛。然而,立管安装不稳的情况时有发生,这不仅影响管道系统的正常运行,还可能埋下安全隐患。下面为您详细剖析固定施工中常见的4个问题及解决办法。

一、支架间距过大

部分施工人员为图省事,未严格按规范设置支架间距。当间距过大时,管道自身重量会使中间部位下垂,导致安装不稳。解决此问题需依据管道规格与材质,参照相关标准确定支架间距。一般来说,管径较小的PE自来水管,支架间距可控制在1.5 - 2米;管径较大时,间距应适当缩小。施工时要精准测量,确保支架均匀分布。

二、固定方式不当

常见的固定方式有抱箍固定和焊接固定。抱箍固定若未拧紧,管道易松动;焊接固定则可能因操作不当损伤管道。对于抱箍固定,安装时要使用扭矩扳手,按规定扭矩拧紧,且定期检查紧固情况。焊接固定需由专业人员操作,采用合适的焊接工艺,焊接前清理管道表面,焊接过程中控制温度与时间,避免管道变形或产生裂纹。

三、基层处理不到位

立管安装的基层墙面或地面若不平整、有油污或松动,会影响固定效果。施工前要对基层进行处理,墙面不平整的需用砂浆找平,地面油污要彻底清理,松动部位要重新夯实或加固。基层处理合格后,再进行管道固定施工,确保固定件能牢固附着。

四、管道补偿未考虑

PE水管受温度变化会产生伸缩。若立管固定时未设置补偿装置,伸缩产生的应力会使固定部位松动。可根据管道长度与温差,合理设置伸缩节或采用自然补偿方式(如利用管道的转弯)。伸缩节安装要符合产品要求,预留足够的伸缩量。

总之,PE自来水管立管安装稳固是保障给排水系统正常运行的关键。施工人员要重视固定施工中的每个环节,从支架设置、固定方式选择到基层处理与补偿考虑,都严格按规范操作,这样才能有效解决安装不稳问题,确保管道系统安全可靠。
