鋼波紋涵管安裝(zhuang)鋪設應平順(shun)、穩固(gu)、管底坡度(du)不(bu)(bu)得出(chu)現反坡,管涵(han)內不(bu)(bu)得有泥(ni)土(tu)、磚石(shi)等(deng)雜物。首先是施工(gong)前,挖掘涵(han)洞的施工(gong)也很重要,為了避免(mian)(mian)路基邊坡遭(zao)到破壞,必須(xu)是相關人員準備(bei)材料及設備(bei),使用防護圍網,以免(mian)(mian)山(shan)石(shi)下滑(hua)造成不(bu)(bu)必要的損失。
確保鋼波紋涵管回填土的質量有這幾種(zhong)方法可用
波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)(han)也叫金(jin)屬(shu)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)(han)或鋼制(zhi)(zhi)波(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)(han)(han)管(guan)(guan)(guan),是指鋪埋在公路(lu),鐵路(lu)下面的(de)(de)涵(han)(han)(han)(han)洞(dong)用(yong)螺紋(wen)(wen)(wen)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan),它(ta)是由波(bo)(bo)形(xing)(xing)金(jin)屬(shu)板卷制(zhi)(zhi)成或用(yong)半圓波(bo)(bo)形(xing)(xing)鋼片拼制(zhi)(zhi)成的(de)(de)圓形(xing)(xing)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan),應用(yong)于公路(lu),鐵路(lu),小橋,通道(dao),擋土(tu)(tu)墻以及(ji)各種礦(kuang)場,巷(xiang)道(dao)擋墻支(zhi)護等(deng)工程(cheng)中的(de)(de)涵(han)(han)(han)(han)洞(dong)(管(guan)(guan)(guan))。波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)(han)是與(yu)鋼筋混凝(ning)土(tu)(tu)管(guan)(guan)(guan)涵(han)(han)(han)(han)相(xiang)比,具有管(guan)(guan)(guan)節薄,重量輕,便于運輸存放,施工工藝簡單(dan),工期短等(deng)優點。鋼波(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)(han)(han)管(guan)(guan)(guan)在安裝(zhuang)時,拼接(jie)處必須清理干凈。以確(que)保拼縫搭(da)接(jie)緊密。
鋼波紋涵管價格
鋼(gang)波紋(wen)涵管接縫(feng)處必須結合緊密(mi),防(fang)水密(mi)封(feng)材料有(you)效。高強螺栓緊固后(hou),在二次(ci)防(fang)腐(fu)處理前,應(ying)在搭接處用密(mi)封(feng)防(fang)水材料(或熱瀝青(qing))涂裝。基礎的地基承載力(li)必須滿(man)足(zu)沒計(ji)要求,嚴禁(jin)超挖回填虛土超過(guo)以及標(biao)高控(kong)制。鋼(gang)波紋(wen)涵管在出廠前應(ying)嚴格(ge)按鋼(gang)質波紋(wen)板加工(gong)驗收標(biao)準進行驗收,并進行必要的預(yu)拼裝。
鋼質(zhi)波(bo)(bo)紋(wen)(wen)板(ban)通道(dao)現場拼裝(zhuang),必須(xu)嚴(yan)格。按(an)設計(ji)以及(ji)鋼質(zhi)波(bo)(bo)紋(wen)(wen)板(ban)通道(dao)施工(gong)安裝(zhuang)規范的要求施工(gong)。外觀規定:鋼波(bo)(bo)紋(wen)(wen)涵(han)管(guan)運到施工(gong)現場后,必須(xu)逐塊檢(jian)查(cha),凡在運輸過程中變形(xing)的鋼板(ban)不(bu)得使(shi)用。鋼波(bo)(bo)紋(wen)(wen)涵(han)管(guan)安裝(zhuang)現行必須(xu)直順(shun),管(guan)口與路堤邊坡(po)坡(po)度應(ying)一(yi)致。
對基底進行平整,換填30-50cm厚的(de)沙礫材(cai)料(liao),密實度達(da)到(dao)90%以上,選擇適當(dang)的(de)流水縱(zong)坡3%左右(you)。定出(chu)每(mei)道涵的(de)中線(xian)和邊線(xian)。鋼(gang)波(bo)紋涵管單體出(chu)廠(chang)時,必須(xu)附有產品質(zhi)量合格(ge)證書(shu),沒(mei)有合格(ge)證書(shu)的(de)一(yi)律不能(neng)出(chu)廠(chang)。必須(xu)采用有效措施,確保鋼(gang)波(bo)紋管回填土質(zhi)量。
基本要求:如果鋼波紋(wen)(wen)管涵(han)(han)長小(xiao)于30米(mi),波紋(wen)(wen)涵(han)(han)管兩側與原涵(han)(han)寬度大于80cm,可(ke)將整(zheng)道波紋(wen)(wen)涵(han)(han)管在下(xia)游或(huo)上游向一端(duan)推進,就(jiu)位(wei)以后,再進行一端(duan)擋墻(qiang)的砌(qi)筑(zhu),四(si)周(zhou)的回(hui)(hui)填(tian)(tian)工作,可(ke)回(hui)(hui)填(tian)(tian)沙礫、碎(sui)石土,砌(qi)筑(zhu)片(pian)石等,頂部采(cai)用漿(jiang)(jiang)砌(qi)片(pian)石或(huo)高壓泵送(song)膨(peng)脹水泥沙漿(jiang)(jiang)。基礎處理,可(ke)回(hui)(hui)填(tian)(tian)沙礫或(huo)砌(qi)筑(zhu)片(pian)石砼。(hanihanbj.com)
