dbzz防水套管管道施工：
1：防水套管主管采用球墨鑄鐵管，橡膠圈承插接口，過橋管采用D325×8焊接鋼管，沿路預埋支管采用D219×6焊接鋼管。
2：施工前需對管件及閥門進行試驗檢測，其壓力等級不應低于管道工作壓力的1.5倍，材料進場后及下管前要對管材及附件進行檢驗，包括文字證明和實物檢查。
3：防水套管管材在運輸，裝卸及堆放過程中嚴禁拋扔或激烈碰撞。管道的鋪設應在驗槽合格后方可進行，在鋪設管道前要對管材，管件等重新進行一次外觀檢查，發現有問題的管材和管件均不得使用。
4：防水套管管材的吊運及放入槽內時，應采用可靠的軟帶吊具，平穩下溝，不得與槽底和槽壁發生劇烈碰撞。配管時沿溝槽分散配置，減少二次搬運，為確保下管位置的準確，需在管內放置帶有中心刻度的水平尺，檢驗時看管道坐標中心線上下垂的中心吊線與水平尺的中心是否重合。
