鋼波紋涵管也(ye)(ye)叫波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)涵(han)(han)，是指鋪埋在公路、鐵路路下的(de)(de)涵(han)(han)洞(dong)用(yong)的(de)(de)螺紋(wen)(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)，它是由波(bo)(bo)(bo)形(xing)(xing)鋼(gang)板卷制成(cheng)或用(yong)波(bo)(bo)(bo)形(xing)(xing)鋼(gang)片組(zu)拼成(cheng)的(de)(de)圓形(xing)(xing)鋼(gang)結(jie)構管(guan)(guan)(guan)(guan)。金屬波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)涵(han)(han)的(de)(de)波(bo)(bo)(bo)紋(wen)(wen)(wen)結(jie)構可(ke)使涵(han)(han)洞(dong)路面受力合理，荷載(zai)分布均勻，并具有一定的(de)(de)抗(kang)變形(xing)(xing)能(neng)力，能(neng)解決北(bei)方寒冷地區(qu)（霜(shuang)凍(dong)）對橋梁(liang)和管(guan)(guan)(guan)(guan)涵(han)(han)砼結(jie)構的(de)(de)破壞問題(ti)；使路表面沒有伸縮縫，提(ti)高(gao)行(xing)車舒適(shi)性；有利于改善軟土(tu)地基結(jie)構與路堤交(jiao)界處的(de)(de)“錯臺(tai)”現象(xiang)，提(ti)高(gao)行(xing)車安全性。波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)涵(han)(han)的(de)(de)工(gong)后營運、養護成(cheng)本低(di)，工(gong)程實(shi)際造價也(ye)(ye)低(di)于同類跨徑(jing)(jing)的(de)(de)橋梁(liang)、涵(han)(han)洞(dong)。鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)管(guan)(guan)(guan)(guan)進出(chu)口(kou)也(ye)(ye)可(ke)按照(zhao)邊坡比例做成(cheng)斜口(kou)，加工(gong)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)徑(jing)(jing)范圍0．5～8 m，管(guan)(guan)(guan)(guan)壁(bi)厚度(du)為3 mm～7 mm，能(neng)夠滿足填土(tu)0．5 ～40 m厚的(de)(de)需(xu)要(yao)。
