鋼波紋涵管也叫波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)(han),是指鋪埋在公路(lu)(lu)(lu)、鐵(tie)路(lu)(lu)(lu)路(lu)(lu)(lu)下(xia)的(de)涵(han)(han)(han)洞用(yong)的(de)螺紋(wen)(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan),它是由波(bo)(bo)(bo)形(xing)鋼板卷制(zhi)成(cheng)或用(yong)波(bo)(bo)(bo)形(xing)鋼片組拼(pin)成(cheng)的(de)圓形(xing)鋼結(jie)構(gou)(gou)管(guan)(guan)。金屬波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)(han)的(de)波(bo)(bo)(bo)紋(wen)(wen)(wen)結(jie)構(gou)(gou)可使涵(han)(han)(han)洞路(lu)(lu)(lu)面受(shou)力(li)(li)合理,荷載分布均勻,并具有(you)一定的(de)抗變形(xing)能(neng)力(li)(li),能(neng)解決北方寒冷(leng)地區(霜凍)對橋(qiao)梁和管(guan)(guan)涵(han)(han)(han)砼(tong)結(jie)構(gou)(gou)的(de)破壞問(wen)題;使路(lu)(lu)(lu)表面沒有(you)伸縮縫,提高行(xing)車舒適性;有(you)利于(yu)改善軟土地基(ji)結(jie)構(gou)(gou)與路(lu)(lu)(lu)堤交(jiao)界(jie)處的(de)“錯臺”現象,提高行(xing)車安(an)全(quan)性。波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)(han)的(de)工(gong)(gong)后營運、養(yang)護成(cheng)本低,工(gong)(gong)程實(shi)際(ji)造價也低于(yu)同類跨徑(jing)的(de)橋(qiao)梁、涵(han)(han)(han)洞。鋼波(bo)(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)進出口也可按照(zhao)邊坡比例(li)做成(cheng)斜口,加(jia)工(gong)(gong)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)徑(jing)范圍(wei)0.5~8 m,管(guan)(guan)壁厚度為3 mm~7 mm,能(neng)夠滿(man)足填土0.5 ~40 m厚的(de)需要(yao)。
