公路(lu)工(gong)程的(de)涵洞一般采用鋼筋混凝土制(zhi)作。現采用鋼波紋涵管(guan)代(dai)替鋼筋混凝土進(jin)行涵洞施工(gong)在國(guo)內時一項新技(ji)術，鋼波紋涵管(guan)以其(qi)性能穩定(ding)、安裝方便(bian)、有(you)利環保、造價低等優(you)點迅速(su)在公路(lu)施工(gong)中代(dai)替了鋼筋混凝土施工(gong)的(de)涵洞，發展前景非常廣闊。

　　波紋管涵的發展前景

　　在公(gong)(gong)(gong)(gong)路(lu)施(shi)工(gong)中(zhong)，應用(yong)(yong)鋼(gang)(gang)波(bo)(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)代替(ti)鋼(gang)(gang)筋(jin)混(hun)凝土進(jin)行(xing)涵(han)(han)洞(dong)施(shi)工(gong)的(de)(de)(de)(de)歷史已(yi)經(jing)有(you)100多年(nian)(nian)了(le)(le)(le)。1896年(nian)(nian)，美(mei)國率先進(jin)行(xing)波(bo)(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)通道、涵(han)(han)管(guan)(guan)的(de)(de)(de)(de)可行(xing)性(xing)研(yan)究(jiu)。其(qi)后，在美(mei)國、加拿大(da)、澳大(da)利亞等(deng)國的(de)(de)(de)(de)公(gong)(gong)(gong)(gong)路(lu)建(jian)設(she)(she)中(zhong)，均采用(yong)(yong)了(le)(le)(le)鋼(gang)(gang)波(bo)(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)進(jin)行(xing)涵(han)(han)洞(dong)的(de)(de)(de)(de)施(shi)工(gong)。1990年(nian)(nian)，日(ri)本高速公(gong)(gong)(gong)(gong)路(lu)設(she)(she)計(ji)，規范制定了(le)(le)(le)波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)設(she)(she)計(ji)技術規范。隨著波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)在世界各地的(de)(de)(de)(de)安裝使(shi)用(yong)(yong)，證明(ming)(ming)了(le)(le)(le)此種(zhong)(zhong)結構在各種(zhong)(zhong)使(shi)用(yong)(yong)情況下的(de)(de)(de)(de)通用(yong)(yong)性(xing)。在我國改革開放后，深圳及大(da)同煤礦開始(shi)從(cong)國外進(jin)口成(cheng)品波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)進(jin)行(xing)涵(han)(han)洞(dong)施(shi)工(gong)。之后，上海市公(gong)(gong)(gong)(gong)路(lu)管(guan)(guan)理(li)處、上海市政工(gong)程設(she)(she)計(ji)研(yan)究(jiu)院、上海同濟(ji)大(da)學(xue)對金屬波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)進(jin)行(xing)了(le)(le)(le)動(dong)、靜載試驗，結果表明(ming)(ming)能滿足設(she)(she)計(ji)使(shi)用(yong)(yong)要求，填補了(le)(le)(le)國內的(de)(de)(de)(de)空白，且迅(xun)速得到推廣應用(yong)(yong)。幕墻一貫(guan)反應用(yong)(yong)于我國各地公(gong)(gong)(gong)(gong)路(lu)設(she)(she)施(shi)建(jian)設(she)(she)當中(zhong)。鋼(gang)(gang)波(bo)(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)投入(ru)到了(le)(le)(le)青海公(gong)(gong)(gong)(gong)路(lu)施(shi)工(gong)當中(zhong)，三年(nian)(nian)的(de)(de)(de)(de)實踐(jian)證明(ming)(ming)，鋼(gang)(gang)波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)在北方寒冷地區完全符合公(gong)(gong)(gong)(gong)路(lu)建(jian)設(she)(she)當中(zhong)的(de)(de)(de)(de)涵(han)(han)洞(dong)施(shi)工(gong)要求。陜西通途交通設(she)(she)施(shi)有(you)限公(gong)(gong)(gong)(gong)司是一家生產(chan)(chan)公(gong)(gong)(gong)(gong)路(lu)涵(han)(han)洞(dong)通道用(yong)(yong)波(bo)(bo)(bo)紋(wen)鋼(gang)(gang)管(guan)(guan)（板(ban)(ban)）的(de)(de)(de)(de)企業(ye)，主要產(chan)(chan)品包(bao)括公(gong)(gong)(gong)(gong)路(lu)涵(han)(han)洞(dong)通道用(yong)(yong)波(bo)(bo)(bo)紋(wen)鋼(gang)(gang)管(guan)(guan)（板(ban)(ban)）、相關配套設(she)(she)施(shi)有(you)橋梁(liang)支(zhi)座、伸縮(suo)縫、鋼(gang)(gang)波(bo)(bo)(bo)紋(wen)腹(fu)板(ban)(ban)橋、聲屏障、鋼(gang)(gang)便橋、土工(gong)材料(liao)、防(fang)水(shui)材料(liao)、金屬掛網(wang)、防(fang)眩(xuan)板(ban)(ban)、公(gong)(gong)(gong)(gong)路(lu)護欄等(deng)交通基礎(chu)設(she)(she)施(shi)和其(qi)他(ta)相應的(de)(de)(de)(de)基礎(chu)設(she)(she)施(shi)。

　　實踐證明，用鋼(gang)波(bo)紋涵(han)管(guan)代替鋼(gang)筋混凝土進行涵(han)洞(dong)施(shi)工(gong)，無論(lun)從施(shi)工(gong)周期、施(shi)工(gong)造價、環保(bao)意義(yi)等方(fang)面都有(you)其不可(ke)比擬的(de)優越性(xing)，且用鋼(gang)波(bo)紋管(guan)涵(han)進行涵(han)洞(dong)施(shi)工(gong)，可(ke)大大提高道路行車(che)的(de)舒(shu)適度(du)與安(an)全性(xing)，避免道路中涵(han)洞(dong)的(de)“錯臺跳車(che)”現形，有(you)利于解決西北地區(qu)寒冷霜凍對砼管(guan)涵(han)結構的(de)破壞問題。
