鋼波紋管洞施(shi)工(gong)(gong)只(zhi)需對(dui)根底(di)和進出口中止處(chu)置(zhi),減少(shao)了水泥、塊石(shi)、片石(shi)或(huo)碎石(shi)、砂(sha)等(deng)的用(yong)。鋼波紋管具有路用(yong)功能(neng),尤其是(shi)(shi)對(dui)地(di)基要(yao)求低、施(shi)工(gong)(gong)簡(jian)易(yi)、能(neng)快速(su)安裝、大(da)(da)大(da)(da)縮短工(gong)(gong)期是(shi)(shi)一般(ban)涵管無法比(bi)較的,在公(gong)路新改(gai)建工(gong)(gong)程、路基維護工(gong)(gong)程中將發揮活躍的效果(guo)。
雞西鋼波紋管有幾種使用方式???
回(hui)填(tian)(tian)土鍍(du)鋅波(bo)紋(wen)鋼涵管兩邊(bian)回(hui)填(tian)(tian)應采用(yong)(yong)砂研(yan)或與路(lu)基填(tian)(tian)料(liao)相同的(de)資料(liao)。波(bo)紋(wen)涵管兩邊(bian)回(hui)填(tian)(tian)應對稱施工,分(fen)層(ceng)回(hui)填(tian)(tian),每(mei)層(ceng)厚度為20cm。鋼波(bo)紋(wen)管兩邊(bian)回(hui)填(tian)(tian)應采用(yong)(yong)振動夯實(shi)機逐層(ceng)夯實(shi)。密實(shi)度不(bu)小于95%。
鋼(gang)波(bo)紋管(guan)兩(liang)邊近處用(yong)(yong)機械夯(hang)實,管(guan)底下(xia)方粗砂(sha)用(yong)(yong)“水密法”震蕩(dang)器振實。鋼(gang)波(bo)紋管(guan)可用(yong)(yong)于不同(tong)的土質地(di)基(ji)(ji),這是非(fei)常好的,可是不同(tong)的土質地(di)基(ji)(ji)中的施工(gong)問題,又困(kun)擾(rao)著人(ren)們,為了幫助(zhu)大家,下(xia)面我們來說說鋼(gang)波(bo)紋管(guan)在(zai)不同(tong)的土質地(di)基(ji)(ji)怎么施工(gong)?

巖石地基波(bo)(bo)紋涵管不(bu)能直接置于巖石或(huo)混凝(ning)土基床上(shang),因過于剛性(xing)的支承,不(bu)但(dan)會下(xia)降管壁自身(shen)所(suo)具有的突出(chu)(chu)柔性(xing),并且還會減小涵管的承載才(cai)干,影(ying)響我(wo)們的出(chu)(chu)行。但(dan)是鋼波(bo)(bo)紋管適(shi)用于公路(lu)排水(shui)施工,這是怎么回(hui)事(shi)呢?
因為鋼波紋(wen)管涵洞(dong)采用規范化(hua)規劃(hua)(hua)、消(xiao)費,規劃(hua)(hua)簡單,消(xiao)費周期(qi)短、施工(gong)工(gong)期(qi)短,現場設(she)備(bei)(bei)不(bu)需運用大型設(she)備(bei)(bei),主(zhu)要為組裝(zhuang)施工(gong)(一(yi)(yi)般一(yi)(yi)道涵洞(dong)的施工(gong)時(shi)(shi)間在(zai)一(yi)(yi)個工(gong)作日(ri)以(yi)內)。預留(liu)拱(gong)度(du)埋設(she)于一(yi)(yi)般土質地基(ji)上(shang)的波紋(wen)管涵,經過(guo)一(yi)(yi)段時(shi)(shi)間后,常會產生一(yi)(yi)定的下沉。
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/
