鋼制波紋涵管易維護,只需做好(hao)(hao)內壁的防護保養即可。鋼波紋(wen)(wen)涵管在高喊凍土(tu)地(di)區,軟土(tu)路基地(di)帶,具有明顯的經濟效益。其良(liang)好(hao)(hao)的整體(ti)性(xing)、可塑性(xing)對地(di)質條件復雜路段抗變形(xing)能(neng)力強。鋼波紋(wen)(wen)涵管經過(guo)了防腐處(chu)理耐久性(xing)高。其良(liang)好(hao)(hao)的導熱(re)性(xing)對凍土(tu)區的路基擾動小,路基穩定。鋼波紋(wen)(wen)涵管出(chu)廠時,應進行出(chu)廠檢(jian)驗。
鋼(gang)制波(bo)紋涵管(guan)運到現場后這樣安裝非常實用(yong)
產(chan)品(pin)需檢驗合(he)格(ge)并附(fu)有產(chan)品(pin)質量(liang)合(he)格(ge)證書(shu)方可出廠。波紋(wen)鋼板運到施工現場后,必須逐塊檢查。

材料出廠時己(ji)進行(xing)鍍(du)鋅(xin)防(fang)腐(fu)處理,運輸工(gong)地后(hou),卸貨(huo)時不(bu)可(ke)直接翻拉,應(ying)采用吊車(che)配(pei)合人工(gong)進行(xing)裝卸,避免損(sun)壞鍍(du)鋅(xin)層。鋼波紋涵(han)管進行(xing)外觀檢查(cha),防(fang)止出現(xian)(xian)損(sun)傷變形、裝卸劃痕、鍍(du)鋅(xin)層損(sun)壞、切口有(you)不(bu)規則鋸齒現(xian)(xian)象。
鋼(gang)波(bo)紋(wen)涵管(guan)采(cai)用工(gong)(gong)廠化生產(chan),生產(chan)不受環境影(ying)響并有利于控制質量(liang)(liang)。鋼(gang)波(bo)紋(wen)涵管(guan)現場拼裝(zhuang)(zhuang),必須嚴(yan)格按照設(she)計以及(ji)鋼(gang)波(bo)紋(wen)涵管(guan)施工(gong)(gong)安裝(zhuang)(zhuang)規范(fan)的要求施工(gong)(gong)。現場施工(gong)(gong)中土建(jian)部(bu)分(fen)驗(yan)收(shou)標(biao)準可(ke)參(can)照交通部(bu)《公路(lu)(lu)工(gong)(gong)程(cheng)質量(liang)(liang)檢驗(yan)評定標(biao)準》JTGF80/1-2004中有關標(biao)準,鋼(gang)波(bo)紋(wen)涵管(guan)外回填土的驗(yan)收(shou)可(ke)歸入路(lu)(lu)基(ji)工(gong)(gong)程(cheng)之中。拼裝(zhuang)(zhuang)施工(gong)(gong),工(gong)(gong)期短(duan)、重(zhong)量(liang)(liang)輕、安裝(zhuang)(zhuang)方便,在高(gao)海(hai)拔地區減少大量(liang)(liang)人工(gong)(gong),并可(ke)在冬季施工(gong)(gong)。(hanihanbj.com)
