鋼波紋涵(han)管涵洞(dong)施(shi)(shi)工(gong)工(gong)藝流程(cheng)可分為(wei)路(lu)堤(di)法和反開槽(cao)回填法,下(xia)面主(zhu)要(yao)(yao)介紹后(hou)者(zhe),因其在(zai)施(shi)(shi)工(gong)過程(cheng)中不影響路(lu)基施(shi)(shi)工(gong)整體的進度(du) 在(zai)山(shan)區修建高速公(gong)路(lu),為(wei)達(da)到終的設(she)計要(yao)(yao)求,深(shen)挖高墳(fen)這種情(qing)況經常能(neng)遇(yu)到,因此產(chan)生的髙墳(fen)方路(lu)堤(di)下(xia)的涵洞(dong)工(gong)程(cheng)越來(lai)越多。
鍍鋅波紋管涵
進岀口可(ke)采用(yong)由(you)制造的金(jin)(jin)屬波紋(wen)管節,有(you)直(zhi)管和與路基邊坡同坡率的斜口兩(liang)種形式;也(ye)可(ke)根據所在地(di)區(qu)的具體情(qing)況采用(yong)漿砌(qi)片石(shi)或干砌(qi)片石(shi)砌(qi)筑。一般在寒(han)冷地(di)區(qu),采用(yong)金(jin)(jin)屬波紋(wen)管節或干砌(qi)片石(shi)。 金(jin)(jin)屬波紋(wen)涵管應(ying)用(yong)于公路養護工程時。
待涵(han)(han)(han)身(shen)及洞(dong)(dong)口主(zhu)體部件運(yun)至施工(gong)(gong)現場后,施工(gong)(gong)單位才能(neng)開始拆除(chu)舊(jiu)涵(han)(han)(han)洞(dong)(dong)的(de)(de)工(gong)(gong)作(zuo),在拆除(chu)舊(jiu)涵(han)(han)(han)洞(dong)(dong)的(de)(de)同時(shi),抓(zhua)緊基(ji)(ji)礎(chu)材料的(de)(de)備料工(gong)(gong)作(zuo),備料完成,并經檢驗合格后方可(ke)進行(xing)基(ji)(ji)坑的(de)(de)開挖工(gong)(gong)作(zuo)。金屬(shu)波(bo)紋涵(han)(han)(han)管應用于(yu)新建公路工(gong)(gong)程時(shi),在定購金屬(shu)波(bo)紋涵(han)(han)(han)管的(de)(de)同時(shi)可(ke)抓(zhua)緊基(ji)(ji)礎(chu)材料的(de)(de)備料和基(ji)(ji)坑的(de)(de)開挖工(gong)(gong)作(zuo)。(hanihanbj.com)
