鋼波紋涵管也叫波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han),是指鋪埋在公路(lu)、鐵(tie)路(lu)路(lu)下的(de)涵(han)洞(dong)用(yong)的(de)螺(luo)紋(wen)(wen)波(bo)(bo)紋(wen)(wen)管(guan)(guan),它是由波(bo)(bo)形(xing)鋼板卷制成(cheng)或用(yong)波(bo)(bo)形(xing)鋼片組拼成(cheng)的(de)圓形(xing)鋼結構(gou)管(guan)(guan)。金屬波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)的(de)波(bo)(bo)紋(wen)(wen)結構(gou)可(ke)使涵(han)洞(dong)路(lu)面受力合理(li),荷載分布均勻,并具有一定的(de)抗變形(xing)能(neng)力,能(neng)解決(jue)北方寒冷地區(霜凍)對橋(qiao)梁(liang)和(he)管(guan)(guan)涵(han)砼結構(gou)的(de)破(po)壞問(wen)題;使路(lu)表面沒(mei)有伸縮縫,提高行車舒適(shi)性(xing);有利于改善軟土地基結構(gou)與路(lu)堤交(jiao)界(jie)處的(de)“錯臺”現象(xiang),提高行車安全性(xing)。波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)的(de)工(gong)后營運、養(yang)護成(cheng)本低,工(gong)程實際造價也低于同(tong)類跨徑的(de)橋(qiao)梁(liang)、涵(han)洞(dong)。鋼波(bo)(bo)紋(wen)(wen)涵(han)管(guan)(guan)進出口也可(ke)按照(zhao)邊坡比例做成(cheng)斜(xie)口,加工(gong)波(bo)(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)徑范(fan)圍0.5~8 m,管(guan)(guan)壁厚度為3 mm~7 mm,能(neng)夠滿足填土0.5 ~40 m厚的(de)需(xu)要(yao)。
