鋼(gang)波紋涵管也叫波(bo)紋(wen)管(guan)(guan)涵(han)(han),是(shi)指鋪埋在(zai)公路(lu)、鐵(tie)路(lu)路(lu)下的涵(han)(han)洞用(yong)的螺(luo)紋(wen)波(bo)紋(wen)管(guan)(guan),它是(shi)由波(bo)形鋼板卷(juan)制成或用(yong)波(bo)形鋼片組拼(pin)成的圓形鋼結構(gou)管(guan)(guan)。金屬波(bo)紋(wen)管(guan)(guan)涵(han)(han)的波(bo)紋(wen)結構(gou)可(ke)使(shi)涵(han)(han)洞路(lu)面受力合(he)理,荷載分布均勻,并(bing)具有一(yi)定的抗變形能力,能解(jie)決北方寒冷地區(霜凍)對橋(qiao)梁(liang)和(he)管(guan)(guan)涵(han)(han)砼結構(gou)的破壞問題;使(shi)路(lu)表(biao)面沒有伸縮(suo)縫,提高(gao)(gao)行車(che)舒適性(xing);有利于改善軟土(tu)(tu)地基結構(gou)與路(lu)堤(di)交(jiao)界處的“錯臺”現象,提高(gao)(gao)行車(che)安全性(xing)。波(bo)紋(wen)管(guan)(guan)涵(han)(han)的工(gong)后(hou)營(ying)運、養(yang)護成本低(di)(di),工(gong)程實(shi)際造價也低(di)(di)于同類跨徑(jing)的橋(qiao)梁(liang)、涵(han)(han)洞。鋼波(bo)紋(wen)涵(han)(han)管(guan)(guan)進出口也可(ke)按照邊(bian)坡比(bi)例(li)做(zuo)成斜(xie)口,加(jia)工(gong)波(bo)紋(wen)管(guan)(guan)管(guan)(guan)徑(jing)范圍0.5~8 m,管(guan)(guan)壁厚(hou)度為(wei)3 mm~7 mm,能夠滿足填土(tu)(tu)0.5 ~40 m厚(hou)的需要。
