dbzz防水套管管道施工：
1：防水套管主管采用球墨铸铁管，橡胶圈承插接口，过桥管采用D325×8焊接钢管，沿路预埋支管采用D219×6焊接钢管。
2：施工前需对管件及阀门进行试验检测，其压力等级不应低于管道工作压力的1.5倍，材料进场后及下管前要对管材及附件进行检验，包括文字证明和实物检查。
3：防水套管管材在运输，装卸及堆放过程中严禁抛扔或激烈碰撞。管道的铺设应在验槽合格后方可进行，在铺设管道前要对管材，管件等重新进行一次外观检查，发现有问题的管材和管件均不得使用。
4：防水套管管材的吊运及放入槽内时，应采用可靠的软带吊具，平稳下沟，不得与槽底和槽壁发生剧烈碰撞。配管时沿沟槽分散配置，减少二次搬运，为确保下管位置的准确，需在管内放置带有中心刻度的水平尺，检验时看管道坐标中心线上下垂的中心吊线与水平尺的中心是否重合。
