鋼波紋涵管也(ye)叫(jiao)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han),是(shi)指鋪(pu)埋在公路(lu)、鐵路(lu)路(lu)下的(de)(de)涵(han)洞(dong)用的(de)(de)螺紋(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan),它是(shi)由波(bo)(bo)(bo)形鋼(gang)板卷(juan)制成(cheng)或用波(bo)(bo)(bo)形鋼(gang)片組拼成(cheng)的(de)(de)圓形鋼(gang)結構管(guan)(guan)。金(jin)屬(shu)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)的(de)(de)波(bo)(bo)(bo)紋(wen)(wen)結構可(ke)(ke)使涵(han)洞(dong)路(lu)面(mian)受力(li)合理,荷載分布均(jun)勻,并具有一定的(de)(de)抗(kang)變形能(neng)(neng)力(li),能(neng)(neng)解(jie)決(jue)北方(fang)寒冷地區(霜(shuang)凍)對橋(qiao)梁和管(guan)(guan)涵(han)砼結構的(de)(de)破壞問題;使路(lu)表(biao)面(mian)沒有伸縮縫,提高行車舒適性(xing);有利于改善軟土(tu)地基結構與路(lu)堤交界處的(de)(de)“錯臺”現象(xiang),提高行車安全性(xing)。波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)的(de)(de)工(gong)后營運、養護(hu)成(cheng)本(ben)低(di),工(gong)程實(shi)際造價也(ye)低(di)于同(tong)類跨徑的(de)(de)橋(qiao)梁、涵(han)洞(dong)。鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)涵(han)管(guan)(guan)進(jin)出口也(ye)可(ke)(ke)按照邊坡比例做成(cheng)斜口,加工(gong)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)徑范圍(wei)0.5~8 m,管(guan)(guan)壁(bi)厚度(du)為3 mm~7 mm,能(neng)(neng)夠滿足(zu)填土(tu)0.5 ~40 m厚的(de)(de)需要(yao)。
