鋼(gang)波(bo)紋涵管的特點:
(1)鋼波紋管涵結構強度(du)高(gao),勢(shi)鋼筋混凝土的(de)1-3倍;對(dui)地(di)基承載能(neng)力、平整度(du)要(yao)求較(jiao)低(di),工程實(shi)際造價比同類跨徑(jing)的(de)橋、涵洞相近(jin)或較(jiao)低(di)。
(2)運(yun)營壽命(ming)長,可(ke)達100多(duo)年。
(3)施工(gong)(gong)周期短,工(gong)(gong)廠集(ji)中(zhong)化生(sheng)產,生(sheng)產不(bu)受環境影(ying)響,有(you)利降低成本(ben)、控(kong)制質量(liang)。
(4)重量輕(qing)、施(shi)工便捷(jie);現(xian)場安裝方(fang)便,不需使用大型設備(bei)。
(5)解決北方寒(han)冷(leng)地區(霜凍)對橋(qiao)梁和(he)管(guan)涵(han)砼結構(gou)的(de)破壞(huai)問題。
(6)減少或根本舍棄(qi)了常(chang)規建材,如水泥(ni)、黃砂、石子、木材的使用(yong),環保意義(yi)深遠。
(7)結構受力情(qing)況合理,荷載分布均勻,并有(you)一定的抗變形能(neng)力。
(8)一年四季可施工,施工不(bu)受季節影響。
鋼(gang)波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)管(guan)(guan)(guan)也(ye)(ye)叫波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)涵(han)(han),是指鋪埋在(zai)公路(lu)、鐵路(lu)路(lu)下的(de)涵(han)(han)洞用(yong)的(de)螺(luo)紋(wen)(wen)(wen)波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan),它是由(you)波(bo)(bo)(bo)(bo)(bo)形(xing)鋼(gang)板(ban)卷制成或用(yong)波(bo)(bo)(bo)(bo)(bo)形(xing)鋼(gang)片組(zu)拼成的(de)圓(yuan)形(xing)鋼(gang)結(jie)構管(guan)(guan)(guan)。金(jin)屬波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)涵(han)(han)的(de)波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)結(jie)構可(ke)使(shi)涵(han)(han)洞路(lu)面受力合理,荷載(zai)分布均勻,并具(ju)有(you)一定(ding)的(de)抗變形(xing)能(neng)力,能(neng)解決(jue)北方寒冷(leng)地(di)區(霜(shuang)凍)對橋(qiao)(qiao)梁(liang)(liang)和管(guan)(guan)(guan)涵(han)(han)砼結(jie)構的(de)破壞問題;使(shi)路(lu)表面沒有(you)伸縮縫,提高行(xing)車(che)舒適(shi)性;有(you)利于改(gai)善(shan)軟土地(di)基結(jie)構與(yu)路(lu)堤交(jiao)界處的(de)“錯臺”現象,提高行(xing)車(che)安全性。波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)涵(han)(han)的(de)工(gong)(gong)后營運、養護成本低(di),工(gong)(gong)程實際造價也(ye)(ye)低(di)于同類跨徑的(de)橋(qiao)(qiao)梁(liang)(liang)、涵(han)(han)洞。鋼(gang)波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)管(guan)(guan)(guan)進出(chu)口也(ye)(ye)可(ke)按照邊坡比(bi)例做成斜口,加工(gong)(gong)波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)徑范圍0.5~8 m,管(guan)(guan)(guan)壁厚度為3 mm~7 mm,能(neng)夠(gou)滿足填土0.5 ~40 m厚的(de)需(xu)要(yao)。
