鋼波紋涵管也叫波(bo)紋(wen)管(guan)(guan)涵(han)(han)，是(shi)指鋪埋在(zai)公路(lu)、鐵路(lu)路(lu)下(xia)的涵(han)(han)洞(dong)用的螺紋(wen)波(bo)紋(wen)管(guan)(guan)，它是(shi)由(you)波(bo)形(xing)(xing)鋼(gang)板卷制成(cheng)或用波(bo)形(xing)(xing)鋼(gang)片(pian)組拼成(cheng)的圓形(xing)(xing)鋼(gang)結構(gou)管(guan)(guan)。金屬(shu)波(bo)紋(wen)管(guan)(guan)涵(han)(han)的波(bo)紋(wen)結構(gou)可(ke)(ke)使涵(han)(han)洞(dong)路(lu)面受力合理，荷載(zai)分布(bu)均勻，并具有(you)(you)一定的抗變形(xing)(xing)能(neng)力，能(neng)解決北方寒(han)冷地(di)區（霜凍）對橋梁(liang)(liang)和管(guan)(guan)涵(han)(han)砼結構(gou)的破壞問題；使路(lu)表面沒有(you)(you)伸縮縫，提高行車(che)舒(shu)適(shi)性；有(you)(you)利于(yu)改(gai)善軟(ruan)土地(di)基結構(gou)與(yu)路(lu)堤交界處的“錯臺”現象，提高行車(che)安全性。波(bo)紋(wen)管(guan)(guan)涵(han)(han)的工(gong)(gong)后營運(yun)、養(yang)護成(cheng)本低，工(gong)(gong)程(cheng)實(shi)際造價也低于(yu)同類跨徑(jing)(jing)的橋梁(liang)(liang)、涵(han)(han)洞(dong)。鋼(gang)波(bo)紋(wen)涵(han)(han)管(guan)(guan)進出(chu)口也可(ke)(ke)按照邊坡比例做成(cheng)斜口，加工(gong)(gong)波(bo)紋(wen)管(guan)(guan)管(guan)(guan)徑(jing)(jing)范圍0．5～8 m，管(guan)(guan)壁(bi)厚度為3 mm～7 mm，能(neng)夠(gou)滿足填(tian)土0．5 ～40 m厚的需要。
