鋼波紋涵管也(ye)叫波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han),是指鋪(pu)埋(mai)在公路、鐵路路下(xia)的(de)(de)涵(han)(han)洞(dong)(dong)用(yong)的(de)(de)螺紋波(bo)(bo)紋管(guan)(guan)(guan),它是由波(bo)(bo)形(xing)鋼(gang)板(ban)卷制(zhi)成(cheng)或(huo)用(yong)波(bo)(bo)形(xing)鋼(gang)片組拼成(cheng)的(de)(de)圓(yuan)形(xing)鋼(gang)結(jie)構管(guan)(guan)(guan)。金屬波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)的(de)(de)波(bo)(bo)紋結(jie)構可(ke)使(shi)涵(han)(han)洞(dong)(dong)路面(mian)受力合理(li),荷載分布均勻,并(bing)具(ju)有一定的(de)(de)抗變(bian)形(xing)能力,能解決北方寒冷(leng)地區(qu)(霜(shuang)凍)對橋(qiao)(qiao)梁和管(guan)(guan)(guan)涵(han)(han)砼結(jie)構的(de)(de)破壞(huai)問題(ti);使(shi)路表面(mian)沒有伸縮縫(feng),提(ti)高行(xing)車(che)(che)舒適性(xing)(xing);有利于改善軟土地基結(jie)構與路堤交界處的(de)(de)“錯臺”現象,提(ti)高行(xing)車(che)(che)安全性(xing)(xing)。波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)的(de)(de)工后(hou)營運、養護(hu)成(cheng)本低(di),工程實際造(zao)價也(ye)低(di)于同類跨徑的(de)(de)橋(qiao)(qiao)梁、涵(han)(han)洞(dong)(dong)。鋼(gang)波(bo)(bo)紋涵(han)(han)管(guan)(guan)(guan)進出口也(ye)可(ke)按照邊(bian)坡比例做(zuo)成(cheng)斜口,加工波(bo)(bo)紋管(guan)(guan)(guan)管(guan)(guan)(guan)徑范圍0.5~8 m,管(guan)(guan)(guan)壁厚(hou)(hou)度為3 mm~7 mm,能夠滿足(zu)填土0.5 ~40 m厚(hou)(hou)的(de)(de)需要。
