鋼波紋涵管的特點:
(1)鋼(gang)(gang)波(bo)紋管涵結構強度高,勢鋼(gang)(gang)筋混凝土的(de)(de)1-3倍;對地基(ji)承載能力、平整度要求較(jiao)低(di),工(gong)程實際造價比同類跨(kua)徑的(de)(de)橋(qiao)、涵洞相近或較(jiao)低(di)。
(2)運營壽命(ming)長(chang),可(ke)達(da)100多年。
(3)施工(gong)周期短,工(gong)廠集中化生產,生產不(bu)受環境影響,有利(li)降低成本、控制質量。
(4)重量輕、施(shi)工便(bian)捷;現場安裝方(fang)便(bian),不需(xu)使用大型設備。
(5)解決北方寒冷(leng)地(di)區(霜(shuang)凍)對橋梁(liang)和管涵砼結構的破壞問題。
(6)減少或根本舍棄了常(chang)規建材,如水泥、黃砂、石子、木材的使用,環保意義(yi)深遠。
(7)結構受力(li)(li)情況合理,荷載分(fen)布均勻,并有一(yi)定的抗變(bian)形能(neng)力(li)(li)。
(8)一年四季(ji)可施工,施工不受(shou)季(ji)節影響。
鋼波紋涵管也叫波(bo)紋管(guan)(guan)(guan)(guan)涵(han),是指鋪埋在公路(lu)、鐵路(lu)路(lu)下的涵(han)洞用(yong)的螺紋波(bo)紋管(guan)(guan)(guan)(guan),它是由(you)波(bo)形鋼板卷(juan)制(zhi)成或用(yong)波(bo)形鋼片組拼成的圓形鋼結構(gou)管(guan)(guan)(guan)(guan)。金屬波(bo)紋管(guan)(guan)(guan)(guan)涵(han)的波(bo)紋結構(gou)可使(shi)涵(han)洞路(lu)面受力(li)合(he)理,荷載分布均勻,并(bing)具有一(yi)定的抗變形能力(li),能解決北方寒冷地區(qu)(霜凍)對橋梁和管(guan)(guan)(guan)(guan)涵(han)砼結構(gou)的破壞問題;使(shi)路(lu)表面沒(mei)有伸縮縫,提高(gao)行車(che)舒適性;有利于(yu)改善(shan)軟土(tu)地基(ji)結構(gou)與路(lu)堤交界(jie)處的“錯臺(tai)”現象,提高(gao)行車(che)安全性。波(bo)紋管(guan)(guan)(guan)(guan)涵(han)的工后營運、養護(hu)成本低(di),工程實際(ji)造價也低(di)于(yu)同類跨徑(jing)的橋梁、涵(han)洞。鋼波(bo)紋涵(han)管(guan)(guan)(guan)(guan)進出口也可按照邊坡比例做成斜口,加工波(bo)紋管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)徑(jing)范(fan)圍0.5~8 m,管(guan)(guan)(guan)(guan)壁(bi)厚(hou)度為(wei)3 mm~7 mm,能夠滿(man)足填土(tu)0.5 ~40 m厚(hou)的需(xu)要。
