鋼波紋涵管也(ye)叫波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)涵(han)(han)(han)，是指(zhi)鋪埋在公路(lu)、鐵路(lu)路(lu)下的涵(han)(han)(han)洞(dong)用(yong)的螺(luo)紋(wen)(wen)波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)，它(ta)是由波(bo)(bo)形(xing)(xing)鋼(gang)板卷制成或(huo)用(yong)波(bo)(bo)形(xing)(xing)鋼(gang)片組拼(pin)成的圓(yuan)形(xing)(xing)鋼(gang)結構管(guan)(guan)(guan)(guan)(guan)。金屬波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)涵(han)(han)(han)的波(bo)(bo)紋(wen)(wen)結構可使涵(han)(han)(han)洞(dong)路(lu)面受力合理，荷(he)載分(fen)布(bu)均(jun)勻，并具有一定的抗變(bian)形(xing)(xing)能力，能解決(jue)北方(fang)寒冷(leng)地(di)(di)區（霜(shuang)凍）對橋梁(liang)和管(guan)(guan)(guan)(guan)(guan)涵(han)(han)(han)砼(tong)結構的破壞(huai)問題(ti)；使路(lu)表面沒(mei)有伸縮縫，提(ti)高行(xing)車舒適(shi)性；有利于改善(shan)軟土地(di)(di)基結構與(yu)路(lu)堤交(jiao)界處的“錯臺(tai)”現象，提(ti)高行(xing)車安(an)全性。波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)涵(han)(han)(han)的工后營運、養護成本低(di)，工程實際(ji)造(zao)價也(ye)低(di)于同類跨徑的橋梁(liang)、涵(han)(han)(han)洞(dong)。鋼(gang)波(bo)(bo)紋(wen)(wen)涵(han)(han)(han)管(guan)(guan)(guan)(guan)(guan)進出口也(ye)可按照邊(bian)坡比例做成斜(xie)口，加工波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)徑范圍0．5～8 m，管(guan)(guan)(guan)(guan)(guan)壁厚度為3 mm～7 mm，能夠滿足填土0．5 ～40 m厚的需要。
