(1)管道安装之前需复测管道地沟,支架是否符合管道安装的标高、坡度和坡向。支架间距是否符合图纸和有关规范的要求。考量到放空和管道运行的工艺需要。
(2)法兰焊缝及其他连接件的设置应便于复检,并不得紧贴墙壁、楼板或管架。
(3)管道安装施工过程中及完工后,应及时填写各种施工技术资料表格并经签证记录,埋地铺设的管道,应做好试压试验,办理隐蔽工程验收,填写隐蔽工程记录并及时回填,这些施工技术资料均应整理存档。
(4)管道穿越剪力墙、梁适宜预留钢套管,但穿越楼板、砖墙可用塑料套管或预留洞,比如卫生间排水支管,只需预留洞。实际见《建筑给水排水及采暖工程施工质量验收规范》。(5排水塑料管道穿越封闭空间内(如管井、厨卫内)宜增加阻火圈,非封闭空间,可以不加阻火圈(如外墙、阳台)。
(6)管道安装工作如有间断,应及时封闭敞开的管口。
(7)管道连接时,不得用强力对口,也不得用加热管子及加偏垫等方法来消除接口端面的空隙偏差、错口或不同心等缺陷。
(8)近年来,给水管材多采用PP-R管,排水管多采用UPVC管。以上两种管材与传统金属管道相比具有自重轻、耐腐蚀、耐压强度高、卫生安全、水流阻力小、使用寿命长、安装方便等特点。期望我的回答对您有用。

敷设在高层建筑室内的塑料排水管道当管径大于等于110mm时，应在下列位置设置阻火圈：
1、明敷立管穿越楼层的贯穿部位；
2、横管穿越防火分区的隔墙和防火墙的两侧；
3、横管穿越管道井井壁或管窿围护墙体的贯穿部位外侧。

1结构施工时，按设计要求坐标、位置、预留孔洞，立管安装前，应校正洞口坐标，如需剔修时，洞口尺寸不得过大更不可损伤受力钢筋。安装前清理现场，并依照结构高度按需支搭操作平台．将己预制好的立管运至安装部位，打开伸缩节，作好插入长度标记，按预留膨胀量20～30mm安装就位立管，并锁固伸缩节螺母，找正、找直立管核查三通及检查口标高无误后，固定管道并按规范要求封堵洞口。2立管安装前，应按图纸坐标，确定卡架位置，预装立管卡架。3土建墙面粉刷后，按预留口位置核对图纸坐标，确定管道中心线后，依次安装管道、管件和伸缩节，并连接各管口。4选用整体式防火圈时，应在按设计或施工规范的要求的楼层部位，依照管径的大小安装阻火圈，将阻火圈套在管段处，然后进行接口联接。5立管安装前确定在楼板中管段位置及长度，并将阻水圈套入该管段中间位置粘接牢固，保证阻水圈在板洞中位置。立管安装完成后，应及时卡固立管并按规范要求支模堵洞。堵洞时应分二次浇注，对有防水要求的房间地面应留好防水密封口。6UPVC排水管穿过楼顶板时，应预留防水刚性套管，并作好屋顶防水与套管间隙的防水密封
