1:防水套管(guan)(guan)主管(guan)(guan)采用球墨鑄鐵管(guan)(guan),橡膠圈(quan)承插接(jie)口,過橋管(guan)(guan)采用D325×8焊接鋼管,沿路(lu)預(yu)埋支管采用D219×6焊接鋼管。
2:施工(gong)前需對管件(jian)及閥(fa)門進(jin)行試驗檢測,其壓力(li)等級不應低于管道工(gong)作(zuo)壓力(li)的1.5倍,材料進場后及下管前要對管材及附(fu)件進行檢(jian)驗,包括文字證明(ming)和實(shi)物檢(jian)查。
3:防(fang)水套(tao)管(guan)(guan)管(guan)(guan)材在(zai)運(yun)輸,裝卸及(ji)堆放過程中(zhong)嚴禁拋扔或激烈碰撞。管(guan)(guan)道的鋪設應在(zai)驗槽(cao)合格后(hou)方可進(jin)行,在(zai)鋪設管(guan)(guan)道前(qian)要對管(guan)(guan)材,管(guan)(guan)件等(deng)重新(xin)進(jin)行一次外觀(guan)檢查,發現有問題的管(guan)(guan)材和(he)管(guan)(guan)件均(jun)不(bu)得使用(yong)。
4:防(fang)水套管(guan)(guan)管(guan)(guan)材的吊(diao)運及放入槽內時(shi),應采用可(ke)靠(kao)的軟(ruan)帶(dai)吊(diao)具,平(ping)穩下(xia)溝,不得與(yu)槽底(di)和槽壁發生劇烈碰撞(zhuang)。配(pei)管(guan)(guan)時(shi)沿(yan)溝槽分散配(pei)置(zhi)(zhi),減少二次搬(ban)運,為確保下(xia)管(guan)(guan)位置(zhi)(zhi)的準確,需在管(guan)(guan)內放置(zhi)(zhi)帶(dai)有中(zhong)心(xin)刻度的水平(ping)尺,檢(jian)驗時(shi)看管(guan)(guan)道坐標中(zhong)心(xin)線上下(xia)垂的中(zhong)心(xin)吊(diao)線與(yu)水平(ping)尺的中(zhong)心(xin)是(shi)否重合。
