鋼波紋涵管也(ye)叫(jiao)波紋(wen)管(guan)(guan)涵(han)(han)，是(shi)指鋪埋在(zai)公路、鐵路路下的(de)涵(han)(han)洞用(yong)的(de)螺(luo)紋(wen)波紋(wen)管(guan)(guan)，它是(shi)由(you)波形(xing)鋼板卷制(zhi)成(cheng)或用(yong)波形(xing)鋼片組拼成(cheng)的(de)圓形(xing)鋼結構(gou)(gou)管(guan)(guan)。金屬波紋(wen)管(guan)(guan)涵(han)(han)的(de)波紋(wen)結構(gou)(gou)可(ke)使(shi)涵(han)(han)洞路面(mian)受力合理，荷(he)載分布均(jun)勻，并(bing)具有(you)一定(ding)的(de)抗變形(xing)能(neng)(neng)力，能(neng)(neng)解決北方寒冷地(di)區(qu)（霜(shuang)凍）對橋梁和管(guan)(guan)涵(han)(han)砼結構(gou)(gou)的(de)破壞問題；使(shi)路表面(mian)沒(mei)有(you)伸縮縫(feng)，提高行車舒適性(xing)；有(you)利于(yu)改(gai)善(shan)軟土(tu)地(di)基結構(gou)(gou)與路堤交界處(chu)的(de)“錯臺”現象，提高行車安(an)全性(xing)。波紋(wen)管(guan)(guan)涵(han)(han)的(de)工(gong)后營運、養護成(cheng)本(ben)低(di)，工(gong)程實際造(zao)價也(ye)低(di)于(yu)同類跨徑(jing)(jing)的(de)橋梁、涵(han)(han)洞。鋼波紋(wen)涵(han)(han)管(guan)(guan)進出口(kou)也(ye)可(ke)按照邊坡(po)比例(li)做成(cheng)斜(xie)口(kou)，加工(gong)波紋(wen)管(guan)(guan)管(guan)(guan)徑(jing)(jing)范圍0．5～8 m，管(guan)(guan)壁厚度為3 mm～7 mm，能(neng)(neng)夠滿足填土(tu)0．5 ～40 m厚的(de)需(xu)要。
