鋼波紋涵管涵(han)洞施工工藝流程可分為路(lu)堤法和反開槽回填法,下面(mian)主要介紹后者(zhe),因其在施工過程中不影響路(lu)基施工整體的進度 在山(shan)區修建(jian)高(gao)速公(gong)路(lu),為達到終(zhong)的設計要求,深挖高(gao)墳這種(zhong)情況經常(chang)能遇(yu)到,因此產生的髙墳方路(lu)堤下的涵(han)洞工程越(yue)來越(yue)多。

進岀口(kou)(kou)可(ke)采用(yong)(yong)由制造的金屬(shu)(shu)波(bo)紋(wen)管(guan)節(jie),有(you)直管(guan)和與路(lu)基邊坡(po)同坡(po)率的斜口(kou)(kou)兩(liang)種形式(shi);也可(ke)根據所在地區的具體情況采用(yong)(yong)漿砌(qi)片(pian)(pian)石(shi)(shi)或干砌(qi)片(pian)(pian)石(shi)(shi)砌(qi)筑(zhu)。一(yi)般在寒冷(leng)地區,采用(yong)(yong)金屬(shu)(shu)波(bo)紋(wen)管(guan)節(jie)或干砌(qi)片(pian)(pian)石(shi)(shi)。 金屬(shu)(shu)波(bo)紋(wen)涵管(guan)應用(yong)(yong)于(yu)公路(lu)養護工程時。
待涵(han)身(shen)及洞口主體部(bu)件運至施工(gong)(gong)現場后,施工(gong)(gong)單位(wei)才能(neng)開始拆除舊(jiu)涵(han)洞的工(gong)(gong)作(zuo),在拆除舊(jiu)涵(han)洞的同時,抓緊(jin)(jin)基(ji)礎材(cai)料(liao)(liao)的備(bei)料(liao)(liao)工(gong)(gong)作(zuo),備(bei)料(liao)(liao)完成,并經檢(jian)驗合格后方可進行基(ji)坑的開挖(wa)(wa)工(gong)(gong)作(zuo)。金屬(shu)波(bo)(bo)紋涵(han)管(guan)應用于新建公(gong)路(lu)工(gong)(gong)程時,在定購金屬(shu)波(bo)(bo)紋涵(han)管(guan)的同時可抓緊(jin)(jin)基(ji)礎材(cai)料(liao)(liao)的備(bei)料(liao)(liao)和基(ji)坑的開挖(wa)(wa)工(gong)(gong)作(zuo)。(hanihanbj.com)
