鋼波紋涵管涵洞施工(gong)(gong)工(gong)(gong)藝流程可分為(wei)路(lu)(lu)堤法和反開(kai)槽回填法，下面主要介紹后者(zhe)，因(yin)其在(zai)施工(gong)(gong)過程中不影響(xiang)路(lu)(lu)基施工(gong)(gong)整(zheng)體的(de)進(jin)度 在(zai)山區(qu)修(xiu)建高速公路(lu)(lu)，為(wei)達到(dao)終的(de)設計要求，深挖(wa)高墳這種(zhong)情(qing)況經常能遇到(dao)，因(yin)此產生的(de)髙墳方路(lu)(lu)堤下的(de)涵洞工(gong)(gong)程越來越多(duo)。

鍍鋅波紋管涵

進岀口可(ke)采用(yong)(yong)由制造的(de)金屬波紋管(guan)(guan)節(jie)，有直(zhi)管(guan)(guan)和與(yu)路(lu)基邊坡同(tong)坡率的(de)斜(xie)口兩種形式；也可(ke)根據(ju)所在(zai)地(di)區的(de)具體(ti)情況采用(yong)(yong)漿砌片(pian)石或干砌片(pian)石砌筑。一般在(zai)寒冷(leng)地(di)區，采用(yong)(yong)金屬波紋管(guan)(guan)節(jie)或干砌片(pian)石。 金屬波紋涵管(guan)(guan)應用(yong)(yong)于公(gong)路(lu)養護(hu)工程時。

橋梁(liang)鋼波(bo)紋(wen)管

待涵(han)身(shen)及洞(dong)口主體部(bu)件運至施(shi)工(gong)(gong)(gong)現場后，施(shi)工(gong)(gong)(gong)單位才能開(kai)始拆除舊(jiu)涵(han)洞(dong)的(de)(de)工(gong)(gong)(gong)作，在(zai)(zai)拆除舊(jiu)涵(han)洞(dong)的(de)(de)同時(shi)，抓緊(jin)基礎(chu)(chu)材料(liao)的(de)(de)備料(liao)工(gong)(gong)(gong)作，備料(liao)完成(cheng)，并(bing)經(jing)檢驗合(he)格后方可(ke)進行基坑(keng)的(de)(de)開(kai)挖工(gong)(gong)(gong)作。金(jin)屬波紋涵(han)管(guan)應用(yong)于新建公(gong)路工(gong)(gong)(gong)程時(shi)，在(zai)(zai)定購金(jin)屬波紋涵(han)管(guan)的(de)(de)同時(shi)可(ke)抓緊(jin)基礎(chu)(chu)材料(liao)的(de)(de)備料(liao)和基坑(keng)的(de)(de)開(kai)挖工(gong)(gong)(gong)作。（hanihanbj.com）
