鋼波紋涵管也(ye)叫波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)涵(han)(han),是指鋪埋(mai)在公路(lu)、鐵路(lu)路(lu)下(xia)的(de)(de)(de)涵(han)(han)洞(dong)用(yong)的(de)(de)(de)螺紋(wen)波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan),它(ta)是由波(bo)(bo)(bo)形(xing)鋼(gang)板卷制成或用(yong)波(bo)(bo)(bo)形(xing)鋼(gang)片組拼成的(de)(de)(de)圓形(xing)鋼(gang)結(jie)構管(guan)(guan)(guan)。金屬波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)涵(han)(han)的(de)(de)(de)波(bo)(bo)(bo)紋(wen)結(jie)構可使涵(han)(han)洞(dong)路(lu)面受力合(he)理,荷載分布(bu)均勻,并(bing)具有一定(ding)的(de)(de)(de)抗變形(xing)能(neng)力,能(neng)解決北(bei)方寒冷(leng)地區(霜(shuang)凍)對橋(qiao)梁和管(guan)(guan)(guan)涵(han)(han)砼結(jie)構的(de)(de)(de)破(po)壞問題;使路(lu)表面沒(mei)有伸縮(suo)縫,提高行(xing)車舒適性;有利于(yu)改(gai)善(shan)軟(ruan)土(tu)地基結(jie)構與(yu)路(lu)堤交界處的(de)(de)(de)“錯臺”現(xian)象,提高行(xing)車安全性。波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)涵(han)(han)的(de)(de)(de)工(gong)后營運(yun)、養護成本(ben)低(di),工(gong)程實際(ji)造價也(ye)低(di)于(yu)同類跨(kua)徑(jing)的(de)(de)(de)橋(qiao)梁、涵(han)(han)洞(dong)。鋼(gang)波(bo)(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)進(jin)出口也(ye)可按照(zhao)邊坡比例(li)做(zuo)成斜口,加工(gong)波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)徑(jing)范圍0.5~8 m,管(guan)(guan)(guan)壁厚(hou)度為3 mm~7 mm,能(neng)夠滿足填土(tu)0.5 ~40 m厚(hou)的(de)(de)(de)需要。
