鋼波紋涵管也叫波(bo)紋(wen)管(guan)(guan)(guan)涵(han)(han),是(shi)指(zhi)鋪埋在(zai)公路(lu)、鐵路(lu)路(lu)下的(de)(de)(de)涵(han)(han)洞(dong)用(yong)的(de)(de)(de)螺紋(wen)波(bo)紋(wen)管(guan)(guan)(guan),它是(shi)由波(bo)形(xing)鋼板卷制成(cheng)或用(yong)波(bo)形(xing)鋼片組拼(pin)成(cheng)的(de)(de)(de)圓形(xing)鋼結構管(guan)(guan)(guan)。金屬波(bo)紋(wen)管(guan)(guan)(guan)涵(han)(han)的(de)(de)(de)波(bo)紋(wen)結構可使(shi)(shi)涵(han)(han)洞(dong)路(lu)面受力(li)(li)合理,荷載分布均勻,并具有一定的(de)(de)(de)抗變(bian)形(xing)能(neng)力(li)(li),能(neng)解決北方寒冷地區(霜(shuang)凍)對橋梁和管(guan)(guan)(guan)涵(han)(han)砼結構的(de)(de)(de)破壞問(wen)題;使(shi)(shi)路(lu)表(biao)面沒有伸縮縫(feng),提(ti)高行車舒適(shi)性(xing);有利于改善軟土(tu)地基結構與路(lu)堤交界(jie)處(chu)的(de)(de)(de)“錯臺”現象,提(ti)高行車安全性(xing)。波(bo)紋(wen)管(guan)(guan)(guan)涵(han)(han)的(de)(de)(de)工(gong)后營(ying)運(yun)、養(yang)護成(cheng)本低(di),工(gong)程實際造價也低(di)于同類跨徑的(de)(de)(de)橋梁、涵(han)(han)洞(dong)。鋼波(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)進出口也可按照(zhao)邊(bian)坡比(bi)例做成(cheng)斜口,加工(gong)波(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)徑范(fan)圍0.5~8 m,管(guan)(guan)(guan)壁厚度為3 mm~7 mm,能(neng)夠滿足填土(tu)0.5 ~40 m厚的(de)(de)(de)需要(yao)。
