鋼波紋涵管的特點:
(1)鋼(gang)(gang)波紋(wen)管涵結構強度高,勢鋼(gang)(gang)筋混凝土(tu)的(de)1-3倍;對地基承載能力、平(ping)整度要求較低,工程實際造價比(bi)同類跨徑的(de)橋、涵洞(dong)相近或較低。
(2)運營壽命長(chang),可(ke)達(da)100多年。
(3)施工(gong)周期(qi)短,工(gong)廠集(ji)中(zhong)化(hua)生產,生產不受環境影響,有利降低成本、控制質量。
(4)重量(liang)輕、施工(gong)便捷;現場安裝(zhuang)方便,不需使(shi)用(yong)大型設(she)備。
(5)解決(jue)北(bei)方寒冷地區(霜凍(dong))對橋梁和管涵砼結構的破(po)壞問題。
(6)減(jian)少或根本(ben)舍棄了常(chang)規建材(cai),如水泥、黃砂(sha)、石子、木材(cai)的使用(yong),環(huan)保意(yi)義(yi)深遠。
(7)結構受(shou)力情況合理,荷載分(fen)布均勻,并(bing)有一定的抗變形能(neng)力。
(8)一年四季(ji)(ji)可施(shi)工,施(shi)工不受季(ji)(ji)節影響(xiang)。
鋼波(bo)紋(wen)(wen)(wen)涵(han)(han)(han)(han)管(guan)也(ye)叫波(bo)紋(wen)(wen)(wen)管(guan)涵(han)(han)(han)(han),是(shi)(shi)指鋪埋在公路(lu)(lu)、鐵(tie)路(lu)(lu)路(lu)(lu)下的(de)涵(han)(han)(han)(han)洞用(yong)(yong)的(de)螺紋(wen)(wen)(wen)波(bo)紋(wen)(wen)(wen)管(guan),它是(shi)(shi)由(you)波(bo)形(xing)(xing)鋼板卷(juan)制成(cheng)(cheng)或(huo)用(yong)(yong)波(bo)形(xing)(xing)鋼片組拼成(cheng)(cheng)的(de)圓(yuan)形(xing)(xing)鋼結(jie)構管(guan)。金屬波(bo)紋(wen)(wen)(wen)管(guan)涵(han)(han)(han)(han)的(de)波(bo)紋(wen)(wen)(wen)結(jie)構可使(shi)涵(han)(han)(han)(han)洞路(lu)(lu)面受力合理,荷載分布均勻,并具有(you)一定的(de)抗(kang)變形(xing)(xing)能力,能解(jie)決(jue)北方寒冷地(di)區(qu)(霜(shuang)凍)對橋梁和管(guan)涵(han)(han)(han)(han)砼結(jie)構的(de)破壞問題;使(shi)路(lu)(lu)表面沒有(you)伸縮(suo)縫,提高(gao)(gao)行車舒適(shi)性(xing);有(you)利(li)于改善軟土地(di)基結(jie)構與路(lu)(lu)堤(di)交界處的(de)“錯臺”現象,提高(gao)(gao)行車安全性(xing)。波(bo)紋(wen)(wen)(wen)管(guan)涵(han)(han)(han)(han)的(de)工(gong)后(hou)營運、養護成(cheng)(cheng)本低,工(gong)程實際造價也(ye)低于同類跨徑(jing)的(de)橋梁、涵(han)(han)(han)(han)洞。鋼波(bo)紋(wen)(wen)(wen)涵(han)(han)(han)(han)管(guan)進出口(kou)也(ye)可按照(zhao)邊坡比例做成(cheng)(cheng)斜口(kou),加(jia)工(gong)波(bo)紋(wen)(wen)(wen)管(guan)管(guan)徑(jing)范圍0.5~8 m,管(guan)壁厚度為(wei)3 mm~7 mm,能夠滿足(zu)填土0.5 ~40 m厚的(de)需要。
