鋼波紋涵管也叫波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管涵(han)(han),是(shi)指鋪埋在公路(lu)(lu)、鐵路(lu)(lu)路(lu)(lu)下(xia)的(de)(de)涵(han)(han)洞用(yong)的(de)(de)螺(luo)紋(wen)(wen)(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管,它是(shi)由波(bo)(bo)(bo)形(xing)(xing)鋼(gang)板(ban)卷制成(cheng)或(huo)用(yong)波(bo)(bo)(bo)形(xing)(xing)鋼(gang)片(pian)組拼成(cheng)的(de)(de)圓形(xing)(xing)鋼(gang)結(jie)構管。金屬波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管涵(han)(han)的(de)(de)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)結(jie)構可(ke)使涵(han)(han)洞路(lu)(lu)面受力合理,荷載分布均勻,并具(ju)有一(yi)定的(de)(de)抗(kang)變形(xing)(xing)能(neng)(neng)力,能(neng)(neng)解決北方(fang)寒(han)冷地(di)區(霜(shuang)凍(dong))對橋梁和(he)管涵(han)(han)砼結(jie)構的(de)(de)破壞問題;使路(lu)(lu)表面沒有伸縮(suo)縫,提(ti)高行車(che)舒(shu)適(shi)性;有利于改(gai)善軟土地(di)基結(jie)構與路(lu)(lu)堤(di)交(jiao)界處的(de)(de)“錯臺”現象,提(ti)高行車(che)安(an)全性。波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管涵(han)(han)的(de)(de)工(gong)后營(ying)運(yun)、養護成(cheng)本低(di),工(gong)程實際造價也低(di)于同類跨(kua)徑的(de)(de)橋梁、涵(han)(han)洞。鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)涵(han)(han)管進出口也可(ke)按(an)照邊(bian)坡比例做成(cheng)斜口,加工(gong)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管管徑范圍0.5~8 m,管壁厚度為3 mm~7 mm,能(neng)(neng)夠滿足填土0.5 ~40 m厚的(de)(de)需(xu)要。
