金(jin)屬(shu)波(bo)紋涵管(guan)也叫金(jin)屬(shu)波(bo)紋管(guan)涵、波(bo)紋管(guan)涵、波(bo)紋涵管(guan)或鋼(gang)制波(bo)紋涵管(guan)，是(shi)指(zhi)鋪埋(mai)在公路，鐵路下(xia)面的(de)涵洞(dong)用(yong)螺紋波(bo)紋管(guan)，它是(shi)由波(bo)形金(jin)屬(shu)板卷制成或用(yong)半(ban)圓波(bo)形鋼(gang)片拼制成的(de)圓形波(bo)紋管(guan)，廣泛應用(yong)于公路，鐵路，小(xiao)橋，通道(dao)(dao)，擋土墻以及各種礦場，巷道(dao)(dao)擋墻支護等工程中的(de)涵洞(dong)（管(guan)）。

         過去(qu)，公路工(gong)(gong)程(cheng)的涵(han)(han)(han)洞(dong)(dong)(dong)一般采用(yong)鋼筋混(hun)凝(ning)土(tu)制作。后來在(zai)公路施(shi)(shi)工(gong)(gong)中，研發(fa)應(ying)用(yong)了金屬(shu)波(bo)(bo)紋(wen)涵(han)(han)(han)管代替(ti)鋼筋混(hun)凝(ning)土(tu)進行(xing)(xing)涵(han)(han)(han)洞(dong)(dong)(dong)施(shi)(shi)工(gong)(gong)。現(xian)在(zai)可以說，采用(yong)金屬(shu)波(bo)(bo)紋(wen)涵(han)(han)(han)管代替(ti)鋼筋混(hun)凝(ning)土(tu)進行(xing)(xing)涵(han)(han)(han)洞(dong)(dong)(dong)施(shi)(shi)工(gong)(gong)在(zai)國內是(shi)一項新技術，金屬(shu)波(bo)(bo)紋(wen)涵(han)(han)(han)管以其性能穩定、安裝方便、有利環保、造(zao)價(jia)低等優點迅速(su)在(zai)公路施(shi)(shi)工(gong)(gong)中代替(ti)了鋼筋混(hun)凝(ning)土(tu)施(shi)(shi)工(gong)(gong)的涵(han)(han)(han)洞(dong)(dong)(dong)，發(fa)展(zhan)前景非(fei)常廣闊。

       實踐證明，用(yong)金屬波紋(wen)涵(han)管代替鋼筋混凝土進行涵(han)洞(dong)(dong)施(shi)(shi)工(gong)，無論從施(shi)(shi)工(gong)周期(qi)、施(shi)(shi)工(gong)造價、環保意義等方面(mian)都(dou)有其不(bu)可比擬(ni)的優越性，且用(yong)金屬波紋(wen)涵(han)管進行涵(han)洞(dong)(dong)施(shi)(shi)工(gong)，可大大提高(gao)道(dao)路行車(che)的舒適(shi)度與安(an)全性，避免道(dao)路中涵(han)洞(dong)(dong)的“錯臺跳車(che)”現形，有利于解決西北及我國寒冷地區(qu)霜凍對砼管涵(han)結構的破壞問題。
