公(gong)路工(gong)程(cheng)的(de)涵(han)(han)(han)洞一(yi)般采用(yong)鋼筋混凝土(tu)制作。現采用(yong)鋼波紋(wen)涵(han)(han)(han)管代替鋼筋混凝土(tu)進(jin)行涵(han)(han)(han)洞施(shi)(shi)工(gong)在國內時一(yi)項新(xin)技術，鋼波紋(wen)涵(han)(han)(han)管以(yi)其(qi)性能穩(wen)定、安裝方便、有利環保、造價低等優點迅速在公(gong)路施(shi)(shi)工(gong)中代替了鋼筋混凝土(tu)施(shi)(shi)工(gong)的(de)涵(han)(han)(han)洞，發展前景非常廣闊。

　　波紋管涵的發展前景

　　在(zai)(zai)公(gong)路(lu)施(shi)工(gong)(gong)中，應用(yong)鋼(gang)(gang)(gang)(gang)波(bo)(bo)(bo)(bo)(bo)紋(wen)涵(han)(han)(han)管(guan)(guan)(guan)(guan)代替鋼(gang)(gang)(gang)(gang)筋混凝(ning)土進(jin)行涵(han)(han)(han)洞施(shi)工(gong)(gong)的(de)(de)(de)(de)歷史已經有100多年(nian)(nian)了(le)。1896年(nian)(nian)，美(mei)國(guo)(guo)率先進(jin)行波(bo)(bo)(bo)(bo)(bo)紋(wen)涵(han)(han)(han)管(guan)(guan)(guan)(guan)通(tong)(tong)道、涵(han)(han)(han)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)可行性研究。其(qi)后，在(zai)(zai)美(mei)國(guo)(guo)、加(jia)拿大、澳大利(li)亞等(deng)國(guo)(guo)的(de)(de)(de)(de)公(gong)路(lu)建(jian)設(she)中，均采用(yong)了(le)鋼(gang)(gang)(gang)(gang)波(bo)(bo)(bo)(bo)(bo)紋(wen)涵(han)(han)(han)管(guan)(guan)(guan)(guan)進(jin)行涵(han)(han)(han)洞的(de)(de)(de)(de)施(shi)工(gong)(gong)。1990年(nian)(nian)，日(ri)本高速公(gong)路(lu)設(she)計(ji)(ji)，規范制定了(le)波(bo)(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)涵(han)(han)(han)設(she)計(ji)(ji)技(ji)術規范。隨著波(bo)(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)涵(han)(han)(han)在(zai)(zai)世界各地的(de)(de)(de)(de)安裝使(shi)(shi)用(yong)，證(zheng)明了(le)此種結構在(zai)(zai)各種使(shi)(shi)用(yong)情況下的(de)(de)(de)(de)通(tong)(tong)用(yong)性。在(zai)(zai)我國(guo)(guo)改(gai)革開放后，深(shen)圳及大同煤礦開始從國(guo)(guo)外進(jin)口成品波(bo)(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)涵(han)(han)(han)進(jin)行涵(han)(han)(han)洞施(shi)工(gong)(gong)。之后，上海市公(gong)路(lu)管(guan)(guan)(guan)(guan)理處、上海市政工(gong)(gong)程(cheng)設(she)計(ji)(ji)研究院、上海同濟大學對金屬(shu)波(bo)(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)涵(han)(han)(han)進(jin)行了(le)動(dong)、靜載試驗，結果表明能滿足設(she)計(ji)(ji)使(shi)(shi)用(yong)要求(qiu)，填補了(le)國(guo)(guo)內的(de)(de)(de)(de)空白，且迅速得到(dao)推廣應用(yong)。幕墻一貫反應用(yong)于(yu)我國(guo)(guo)各地公(gong)路(lu)設(she)施(shi)建(jian)設(she)當(dang)中。鋼(gang)(gang)(gang)(gang)波(bo)(bo)(bo)(bo)(bo)紋(wen)涵(han)(han)(han)管(guan)(guan)(guan)(guan)投(tou)入到(dao)了(le)青海公(gong)路(lu)施(shi)工(gong)(gong)當(dang)中，三(san)年(nian)(nian)的(de)(de)(de)(de)實(shi)踐(jian)證(zheng)明，鋼(gang)(gang)(gang)(gang)波(bo)(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)涵(han)(han)(han)在(zai)(zai)北方(fang)寒冷地區完全符(fu)合公(gong)路(lu)建(jian)設(she)當(dang)中的(de)(de)(de)(de)涵(han)(han)(han)洞施(shi)工(gong)(gong)要求(qiu)。陜西通(tong)(tong)途交通(tong)(tong)設(she)施(shi)有限(xian)公(gong)司(si)是一家生產公(gong)路(lu)涵(han)(han)(han)洞通(tong)(tong)道用(yong)波(bo)(bo)(bo)(bo)(bo)紋(wen)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)(guan)（板）的(de)(de)(de)(de)企(qi)業，主要產品包括公(gong)路(lu)涵(han)(han)(han)洞通(tong)(tong)道用(yong)波(bo)(bo)(bo)(bo)(bo)紋(wen)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)(guan)（板）、相(xiang)關配套設(she)施(shi)有橋(qiao)梁支座、伸(shen)縮縫、鋼(gang)(gang)(gang)(gang)波(bo)(bo)(bo)(bo)(bo)紋(wen)腹板橋(qiao)、聲屏障、鋼(gang)(gang)(gang)(gang)便橋(qiao)、土工(gong)(gong)材料(liao)、防水材料(liao)、金屬(shu)掛網、防眩板、公(gong)路(lu)護欄等(deng)交通(tong)(tong)基(ji)礎設(she)施(shi)和其(qi)他(ta)相(xiang)應的(de)(de)(de)(de)基(ji)礎設(she)施(shi)。

　　實踐證明，用(yong)鋼(gang)波紋涵管代替(ti)鋼(gang)筋混凝土進(jin)行涵洞施(shi)工(gong)，無論從施(shi)工(gong)周期、施(shi)工(gong)造價、環保意義等方面都有(you)其不可(ke)比(bi)擬(ni)的優越性，且用(yong)鋼(gang)波紋管涵進(jin)行涵洞施(shi)工(gong)，可(ke)大大提高道路(lu)行車的舒適度與安(an)全性，避免(mian)道路(lu)中(zhong)涵洞的“錯臺(tai)跳車”現形，有(you)利于解決西(xi)北(bei)地(di)區寒冷霜(shuang)凍對(dui)砼管涵結構的破壞問題(ti)。
