鋼波紋涵管也叫(jiao)波(bo)紋(wen)管(guan)(guan)涵(han)(han),是指鋪(pu)埋在公(gong)路(lu)、鐵(tie)路(lu)路(lu)下的(de)(de)(de)涵(han)(han)洞用(yong)的(de)(de)(de)螺紋(wen)波(bo)紋(wen)管(guan)(guan),它是由波(bo)形鋼(gang)板卷(juan)制(zhi)成或用(yong)波(bo)形鋼(gang)片組拼成的(de)(de)(de)圓形鋼(gang)結構(gou)管(guan)(guan)。金屬波(bo)紋(wen)管(guan)(guan)涵(han)(han)的(de)(de)(de)波(bo)紋(wen)結構(gou)可使涵(han)(han)洞路(lu)面(mian)受(shou)力合(he)理,荷載(zai)分(fen)布(bu)均勻(yun),并具有一定的(de)(de)(de)抗變(bian)形能(neng)(neng)力,能(neng)(neng)解(jie)決(jue)北方寒冷(leng)地區(霜凍)對橋梁和管(guan)(guan)涵(han)(han)砼結構(gou)的(de)(de)(de)破壞問題;使路(lu)表(biao)面(mian)沒有伸(shen)縮(suo)縫,提高(gao)行(xing)車舒適性;有利于(yu)改(gai)善軟土地基結構(gou)與路(lu)堤(di)交界處的(de)(de)(de)“錯(cuo)臺”現象,提高(gao)行(xing)車安(an)全性。波(bo)紋(wen)管(guan)(guan)涵(han)(han)的(de)(de)(de)工(gong)(gong)(gong)后營(ying)運、養護成本低(di),工(gong)(gong)(gong)程實際造價也低(di)于(yu)同(tong)類跨徑的(de)(de)(de)橋梁、涵(han)(han)洞。鋼(gang)波(bo)紋(wen)涵(han)(han)管(guan)(guan)進出口也可按照邊(bian)坡比(bi)例做成斜口,加(jia)工(gong)(gong)(gong)波(bo)紋(wen)管(guan)(guan)管(guan)(guan)徑范圍0.5~8 m,管(guan)(guan)壁厚度為(wei)3 mm~7 mm,能(neng)(neng)夠滿足填土0.5 ~40 m厚的(de)(de)(de)需要。
