鋼波紋涵管的特點:
(1)鋼波紋管涵(han)結構強度(du)高(gao),勢鋼筋混凝(ning)土的1-3倍(bei);對地基承載能力、平整度(du)要求較(jiao)低,工(gong)程實際(ji)造價(jia)比同類跨徑的橋、涵(han)洞相近(jin)或(huo)較(jiao)低。
(2)運營壽命長,可達100多年。
(3)施工周期(qi)短,工廠(chang)集中(zhong)化生(sheng)產,生(sheng)產不受(shou)環境影響,有利降低(di)成本、控制質(zhi)量。
(4)重量輕、施工便捷;現場安(an)裝方便,不需(xu)使(shi)用大(da)型設(she)備。
(5)解決北方(fang)寒冷地(di)區(霜凍)對橋(qiao)梁和管涵砼結構(gou)的破壞(huai)問題。
(6)減少(shao)或根(gen)本舍棄(qi)了常(chang)規(gui)建材(cai),如水泥、黃砂、石子、木材(cai)的使用,環保(bao)意義深遠。
(7)結構(gou)受(shou)力情況合(he)理(li),荷載分布均勻,并有(you)一定的抗(kang)變形能力。
(8)一年四(si)季可施(shi)工(gong),施(shi)工(gong)不受季節影響。
鋼波紋涵管也叫波(bo)(bo)(bo)紋(wen)(wen)管(guan)涵(han)(han),是指鋪埋在公路(lu)(lu)、鐵(tie)路(lu)(lu)路(lu)(lu)下的涵(han)(han)洞(dong)用的螺紋(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)管(guan),它是由波(bo)(bo)(bo)形(xing)(xing)鋼(gang)板卷制(zhi)成(cheng)(cheng)或用波(bo)(bo)(bo)形(xing)(xing)鋼(gang)片(pian)組(zu)拼(pin)成(cheng)(cheng)的圓形(xing)(xing)鋼(gang)結構(gou)管(guan)。金屬波(bo)(bo)(bo)紋(wen)(wen)管(guan)涵(han)(han)的波(bo)(bo)(bo)紋(wen)(wen)結構(gou)可使涵(han)(han)洞(dong)路(lu)(lu)面(mian)受力合理,荷載分布均勻(yun),并具有(you)一定的抗變形(xing)(xing)能(neng)力,能(neng)解(jie)決北方寒冷地(di)區(霜凍)對橋梁和管(guan)涵(han)(han)砼結構(gou)的破壞問題(ti);使路(lu)(lu)表面(mian)沒有(you)伸(shen)縮縫,提高行(xing)車舒(shu)適性(xing);有(you)利于改(gai)善(shan)軟土(tu)地(di)基(ji)結構(gou)與(yu)路(lu)(lu)堤(di)交界處的“錯臺”現象,提高行(xing)車安全性(xing)。波(bo)(bo)(bo)紋(wen)(wen)管(guan)涵(han)(han)的工(gong)后營運、養(yang)護成(cheng)(cheng)本低,工(gong)程實際造價也低于同類跨徑的橋梁、涵(han)(han)洞(dong)。鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)涵(han)(han)管(guan)進出口(kou)也可按照邊坡比例(li)做成(cheng)(cheng)斜(xie)口(kou),加工(gong)波(bo)(bo)(bo)紋(wen)(wen)管(guan)管(guan)徑范圍0.5~8 m,管(guan)壁厚(hou)度為(wei)3 mm~7 mm,能(neng)夠滿足填土(tu)0.5 ~40 m厚(hou)的需要(yao)。
