鋼波紋涵管也(ye)叫(jiao)波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)，是指鋪埋(mai)在公路、鐵路路下(xia)的涵(han)(han)洞(dong)用(yong)的螺紋(wen)波(bo)(bo)(bo)紋(wen)管(guan)(guan)，它(ta)是由波(bo)(bo)(bo)形(xing)(xing)(xing)鋼(gang)板卷制成(cheng)(cheng)或用(yong)波(bo)(bo)(bo)形(xing)(xing)(xing)鋼(gang)片(pian)組拼成(cheng)(cheng)的圓形(xing)(xing)(xing)鋼(gang)結(jie)構管(guan)(guan)。金屬波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)的波(bo)(bo)(bo)紋(wen)結(jie)構可(ke)使涵(han)(han)洞(dong)路面受力合理，荷載分布均勻(yun)，并具有一定的抗變形(xing)(xing)(xing)能(neng)力，能(neng)解決北方寒冷地區(qu)（霜凍）對橋梁(liang)和(he)管(guan)(guan)涵(han)(han)砼結(jie)構的破壞問(wen)題；使路表面沒有伸縮縫，提高行車舒(shu)適性；有利(li)于(yu)改(gai)善軟(ruan)土地基結(jie)構與路堤交界處的“錯臺”現象，提高行車安全性。波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)的工(gong)(gong)后營(ying)運、養護(hu)成(cheng)(cheng)本(ben)低，工(gong)(gong)程實際造價也(ye)低于(yu)同類(lei)跨徑的橋梁(liang)、涵(han)(han)洞(dong)。鋼(gang)波(bo)(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)進出口也(ye)可(ke)按照邊坡比例(li)做成(cheng)(cheng)斜口，加工(gong)(gong)波(bo)(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)徑范圍(wei)0．5～8 m，管(guan)(guan)壁厚(hou)度為3 mm～7 mm，能(neng)夠滿足填土0．5 ～40 m厚(hou)的需要。
