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(yù)埋支管采用D219×6焊接鋼管。
2：施工前需對(duì)管件及閥門進(jìn)行試驗(yàn)檢測(cè)，其壓力等級(jí)不應(yīng)低于管道工作壓力的1.5倍，材料進(jìn)場(chǎng)后及下管前要對(duì)管材及附件進(jìn)行檢驗(yàn)，包括文字證明和實(shí)物檢查。
3：防水套管管材在運(yùn)輸，裝卸及堆放過程中嚴(yán)禁拋扔或激烈碰撞。管道的鋪設(shè)應(yīng)在驗(yàn)槽合格后方可進(jìn)行，在鋪設(shè)管道前要對(duì)管材，管件等重新進(jìn)行一次外觀檢查，發(fā)現(xiàn)有問題的管材和管件均不得使用。
4：防水套管管材的吊運(yùn)及放入槽內(nèi)時(shí)，應(yīng)采用可靠的軟帶吊具，平穩(wěn)下溝，不得與槽底和槽壁發(fā)生劇烈碰撞。配管時(shí)沿溝槽分散配置，減少二次搬運(yùn)，為確保下管位置的準(zhǔn)確，需在管內(nèi)放置帶有中心刻度的水平尺，檢驗(yàn)時(shí)看管道坐標(biāo)中心線上下垂的中心吊線與水平尺的中心是否重合。
