鋼波紋管洞施工(gong)(gong)(gong)(gong)(gong)只需對根(gen)底和進(jin)出口(kou)中(zhong)止處置,減少了水(shui)泥、塊(kuai)石(shi)、片石(shi)或碎石(shi)、砂(sha)等的用。鋼波(bo)紋管具(ju)有路用功能,尤(you)其是對地基(ji)要求低、施工(gong)(gong)(gong)(gong)(gong)簡(jian)易、能快速安裝、大(da)大(da)縮短工(gong)(gong)(gong)(gong)(gong)期是一般(ban)涵管無法比較的,在公路新改建工(gong)(gong)(gong)(gong)(gong)程(cheng)、路基(ji)維護工(gong)(gong)(gong)(gong)(gong)程(cheng)中(zhong)將發揮(hui)活躍的效果。

回填(tian)土鍍鋅(xin)波紋(wen)鋼涵管(guan)(guan)兩邊回填(tian)應采用砂研或與路基填(tian)料(liao)相同的資料(liao)。波紋(wen)涵管(guan)(guan)兩邊回填(tian)應對稱施工,分層回填(tian),每層厚度為20cm。鋼波紋(wen)管(guan)(guan)兩邊回填(tian)應采用振動夯(hang)實(shi)機逐(zhu)層夯(hang)實(shi)。密實(shi)度不小于95%。
鋼波(bo)紋(wen)管兩邊近處用機械夯(hang)實,管底下(xia)方粗砂(sha)用“水(shui)密法”震蕩器振(zhen)實。鋼波(bo)紋(wen)管可(ke)用于不(bu)(bu)同的土(tu)質地基(ji),這是非(fei)常好的,可(ke)是不(bu)(bu)同的土(tu)質地基(ji)中的施(shi)工(gong)(gong)問題,又(you)困擾著人們,為了幫助大家,下(xia)面我們來說說鋼波(bo)紋(wen)管在不(bu)(bu)同的土(tu)質地基(ji)怎(zen)么施(shi)工(gong)(gong)?

巖石地(di)基(ji)波紋涵管(guan)(guan)不能直接置于(yu)巖石或混(hun)凝土基(ji)床上(shang),因(yin)過于(yu)剛性(xing)的(de)支承,不但會下降管(guan)(guan)壁自身所具有的(de)突出(chu)柔性(xing),并(bing)且還會減(jian)小涵管(guan)(guan)的(de)承載才(cai)干(gan),影(ying)響我們的(de)出(chu)行。但是鋼波紋管(guan)(guan)適用(yong)于(yu)公路排水施工,這是怎么(me)回事呢?
因(yin)為(wei)鋼波(bo)紋管(guan)涵洞采用規(gui)范化規(gui)劃、消費(fei),規(gui)劃簡單(dan),消費(fei)周期短、施(shi)工(gong)工(gong)期短,現場(chang)設(she)備(bei)不(bu)需運用大(da)型設(she)備(bei),主(zhu)要為(wei)組(zu)裝施(shi)工(gong)(一(yi)般一(yi)道(dao)涵洞的(de)施(shi)工(gong)時間在一(yi)個工(gong)作日(ri)以內)。預留拱度埋設(she)于一(yi)般土(tu)質地基上(shang)的(de)波(bo)紋管(guan)涵,經過一(yi)段時間后,常(chang)會產生一(yi)定的(de)下沉。
并且往往是管道中部大于兩端。因而,鋪設于路堤下的波紋管的管身要設置預留拱度。其大小根據地基土或許呈現的下沉量,涵底縱坡和填土高度等因素歸納考慮,一般可為管長的0.6%~1%,醉大不宜大于2%,以確保管道中部不呈現洼陷或滑坡。//hanihanbj.com/
