在上海新開(kai)(kai)河試驗(yan)涵(han)直徑(jing)4m,與同跨徑(jing)箱涵(han)相(xiang)比,新開(kai)(kai)河試驗(yan)涵(han)節(jie)省5萬(wan)元,節(jie)約(yue)費用(yong)10%左右。在國內獲得多專(zhuan)利,1997年(nian)(nian)開(kai)(kai)始(shi)在青藏多年(nian)(nian)凍土區研究應用(yong)同時(shi)專(zhuan)家們公布(bu)鋼(gang)制波紋(wen)管(guan)應用論文,通過現場施工以認(ren)證了(le)金屬波紋涵管的優(you)越性和施工性。
鋼波紋涵管的(de)工(gong)藝要求你知道幾點(dian)?
鋼波(bo)(bo)紋(wen)涵(han)(han)管(guan)的正常使用(yong)溫度在150℃以內,嚴禁用(yong)氣割或電焊破壞(huai)鋼波(bo)(bo)紋(wen)涵(han)(han)管(guan)表層(ceng)及基(ji)體。鋼波(bo)(bo)紋(wen)涵(han)(han)管(guan)雖然屬于免維護(hu)產品,但(dan)一般每半(ban)年要(yao)進行一次檢查,發現外(wai)表變形(xing)、異常、防護(hu)層(ceng)脫落(luo)等,要(yao)隨時進行處(chu)理。如果出現較大(da)質量問題,要(yao)立即通知前來處(chu)理;
鐵路鋼波紋(wen)管
鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)涵管(guan)(guan)使(shi)用(yong)年(nian)限(xian)超過10年(nian)以上(shang),如果表面(mian)防護(hu)(hu)層出現(xian)大面(mian)積破(po)損,為延長使(shi)用(yong)壽命(ming),可自行進行石油瀝青漆防護(hu)(hu)處(chu)理,也(ye)可聯系生(sheng)(sheng)產(chan)廠商對鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)涵管(guan)(guan)表面(mian)整體進行防護(hu)(hu)處(chu)理;波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵的長處(chu):鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)涵管(guan)(guan)工廠生(sheng)(sheng)產(chan)時間短、安(an)裝(zhuang)方便(bian)快捷(jie)、施工工期(qi)短、節約施工費、耐久性、維護(hu)(hu)費用(yong)低、利于環保(bao)。涵管(guan)(guan)、波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵、鋼(gang)制波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵洞、金屬(shu)波(bo)(bo)(bo)紋(wen)(wen)(wen)涵管(guan)(guan)在場安(an)裝(zhuang)便(bian)捷(jie),不需運用(yong)大型設(she)施。
不(bu)(bu)承擔鋼(gang)波紋涵(han)管因(yin)超承載符合(he)作用下的(de)變形及失(shi)(shi)效損失(shi)(shi);鋼(gang)波紋涵(han)管的(de)使用注意事項:施(shi)行工(gong)廠集中(zhong)化出產,出產不(bu)(bu)受背景影(ying)響,有幫(bang)助減低成(cheng)本、扼(e)制品質。就青藏公(gong)路(lu)來(lai)說(shuo),每道波紋管涵(han)工(gong)程造價(jia)比同樣孔徑的(de)鋼(gang)筋混(hun)凝土蓋板涵(han)低4萬(wan)多(duo)元。(hanihanbj.com)
