鋼波紋涵管也(ye)叫波(bo)(bo)(bo)(bo)(bo)紋管(guan)涵(han)(han)(han),是指(zhi)鋪埋在公(gong)路(lu)、鐵路(lu)路(lu)下的(de)(de)涵(han)(han)(han)洞用的(de)(de)螺紋波(bo)(bo)(bo)(bo)(bo)紋管(guan),它是由波(bo)(bo)(bo)(bo)(bo)形(xing)(xing)鋼板卷制成或用波(bo)(bo)(bo)(bo)(bo)形(xing)(xing)鋼片組拼(pin)成的(de)(de)圓形(xing)(xing)鋼結構(gou)(gou)管(guan)。金(jin)屬(shu)波(bo)(bo)(bo)(bo)(bo)紋管(guan)涵(han)(han)(han)的(de)(de)波(bo)(bo)(bo)(bo)(bo)紋結構(gou)(gou)可使(shi)涵(han)(han)(han)洞路(lu)面受力合理(li),荷(he)載分布均勻(yun),并具(ju)有(you)一定的(de)(de)抗變形(xing)(xing)能(neng)力,能(neng)解(jie)決北方(fang)寒冷(leng)地區(霜凍)對橋(qiao)梁和管(guan)涵(han)(han)(han)砼(tong)結構(gou)(gou)的(de)(de)破壞問(wen)題;使(shi)路(lu)表面沒(mei)有(you)伸縮(suo)縫,提高行車舒適性;有(you)利于改善軟土(tu)地基結構(gou)(gou)與路(lu)堤交界處的(de)(de)“錯(cuo)臺”現(xian)象,提高行車安(an)全(quan)性。波(bo)(bo)(bo)(bo)(bo)紋管(guan)涵(han)(han)(han)的(de)(de)工(gong)后(hou)營運、養(yang)護成本低(di),工(gong)程實際(ji)造價(jia)也(ye)低(di)于同(tong)類(lei)跨徑(jing)的(de)(de)橋(qiao)梁、涵(han)(han)(han)洞。鋼波(bo)(bo)(bo)(bo)(bo)紋涵(han)(han)(han)管(guan)進(jin)出口(kou)也(ye)可按(an)照邊坡比例做成斜(xie)口(kou),加工(gong)波(bo)(bo)(bo)(bo)(bo)紋管(guan)管(guan)徑(jing)范圍0.5~8 m,管(guan)壁厚(hou)度為(wei)3 mm~7 mm,能(neng)夠(gou)滿足填土(tu)0.5 ~40 m厚(hou)的(de)(de)需要。
