鋼波紋涵管也(ye)(ye)叫波(bo)(bo)紋(wen)管(guan)(guan)涵(han),是指鋪(pu)埋(mai)在公路、鐵路路下的(de)涵(han)洞用(yong)的(de)螺紋(wen)波(bo)(bo)紋(wen)管(guan)(guan),它是由波(bo)(bo)形(xing)鋼(gang)板(ban)卷制(zhi)成或用(yong)波(bo)(bo)形(xing)鋼(gang)片組拼成的(de)圓形(xing)鋼(gang)結構(gou)(gou)管(guan)(guan)。金屬波(bo)(bo)紋(wen)管(guan)(guan)涵(han)的(de)波(bo)(bo)紋(wen)結構(gou)(gou)可使涵(han)洞路面(mian)受力(li)合(he)理,荷載分布均(jun)勻,并具有(you)一定(ding)的(de)抗(kang)變形(xing)能(neng)(neng)力(li),能(neng)(neng)解決北方寒冷地(di)區(霜凍(dong))對橋梁和管(guan)(guan)涵(han)砼結構(gou)(gou)的(de)破壞(huai)問題;使路表面(mian)沒(mei)有(you)伸(shen)縮縫,提高行(xing)車(che)舒適性;有(you)利于改善軟土地(di)基結構(gou)(gou)與路堤(di)交界(jie)處的(de)“錯臺”現象,提高行(xing)車(che)安(an)全性。波(bo)(bo)紋(wen)管(guan)(guan)涵(han)的(de)工后(hou)營(ying)運、養護(hu)成本低,工程實(shi)際(ji)造價也(ye)(ye)低于同類跨(kua)徑(jing)的(de)橋梁、涵(han)洞。鋼(gang)波(bo)(bo)紋(wen)涵(han)管(guan)(guan)進出(chu)口也(ye)(ye)可按照(zhao)邊坡比例做(zuo)成斜(xie)口,加工波(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)徑(jing)范圍0.5~8 m,管(guan)(guan)壁(bi)厚度為3 mm~7 mm,能(neng)(neng)夠(gou)滿足(zu)填(tian)土0.5 ~40 m厚的(de)需要。
