鋼波紋涵管的特點:
(1)鋼波(bo)紋管涵結(jie)構強度高,勢鋼筋混凝土的1-3倍;對(dui)地基承載能力、平整度要求較(jiao)低,工程實際(ji)造價比同(tong)類跨徑(jing)的橋(qiao)、涵洞相(xiang)近或較(jiao)低。
(2)運(yun)營壽命長,可達100多年。
(3)施工周期短,工廠集中化生產(chan),生產(chan)不受(shou)環境影(ying)響,有利降低成(cheng)本、控制質量。
(4)重(zhong)量輕、施工便捷;現場安裝方便,不需使用大型(xing)設備。
(5)解決北方寒(han)冷地區(霜凍(dong))對橋梁(liang)和管涵砼結構的破壞問題。
(6)減少或(huo)根(gen)本舍(she)棄了常規建材,如水泥、黃砂、石(shi)子、木材的使(shi)用,環(huan)保(bao)意(yi)義(yi)深遠。
(7)結構(gou)受力情況合(he)理(li),荷載分布均勻,并有一定的抗變形能力。
(8)一年(nian)四季(ji)可(ke)施(shi)工,施(shi)工不受季(ji)節影響。
鋼波(bo)(bo)(bo)紋涵(han)(han)管(guan)(guan)也叫波(bo)(bo)(bo)紋管(guan)(guan)涵(han)(han),是(shi)指鋪埋在公路(lu)、鐵路(lu)路(lu)下的(de)(de)涵(han)(han)洞(dong)用(yong)的(de)(de)螺紋波(bo)(bo)(bo)紋管(guan)(guan),它(ta)是(shi)由波(bo)(bo)(bo)形(xing)鋼板卷制成(cheng)或(huo)用(yong)波(bo)(bo)(bo)形(xing)鋼片組拼成(cheng)的(de)(de)圓形(xing)鋼結(jie)(jie)構管(guan)(guan)。金(jin)屬波(bo)(bo)(bo)紋管(guan)(guan)涵(han)(han)的(de)(de)波(bo)(bo)(bo)紋結(jie)(jie)構可使涵(han)(han)洞(dong)路(lu)面(mian)受力合理,荷(he)載分布均勻(yun),并(bing)具有(you)一定的(de)(de)抗變形(xing)能(neng)(neng)力,能(neng)(neng)解決北方寒冷地區(霜(shuang)凍)對橋梁(liang)和管(guan)(guan)涵(han)(han)砼結(jie)(jie)構的(de)(de)破壞問題;使路(lu)表面(mian)沒有(you)伸縮(suo)縫,提高(gao)行車(che)舒適性(xing);有(you)利于改(gai)善軟土地基結(jie)(jie)構與路(lu)堤交界處的(de)(de)“錯臺”現(xian)象,提高(gao)行車(che)安全性(xing)。波(bo)(bo)(bo)紋管(guan)(guan)涵(han)(han)的(de)(de)工后營(ying)運(yun)、養護成(cheng)本低,工程實(shi)際造價(jia)也低于同類跨徑的(de)(de)橋梁(liang)、涵(han)(han)洞(dong)。鋼波(bo)(bo)(bo)紋涵(han)(han)管(guan)(guan)進出口也可按(an)照邊(bian)坡(po)比例做成(cheng)斜口,加工波(bo)(bo)(bo)紋管(guan)(guan)管(guan)(guan)徑范圍0.5~8 m,管(guan)(guan)壁厚度為(wei)3 mm~7 mm,能(neng)(neng)夠(gou)滿(man)足填土0.5 ~40 m厚的(de)(de)需(xu)要。
