在(zai)上海(hai)新開河試驗涵(han)直徑(jing)4m,與同跨徑(jing)箱涵(han)相(xiang)比,新開河試驗涵(han)節省5萬元,節約(yue)費用10%左右。在(zai)國內獲得多專利,1997年(nian)(nian)開始在(zai)青藏(zang)多年(nian)(nian)凍土(tu)區研究應用同時專家們公(gong)布鋼(gang)制波(bo)紋管應(ying)用論文,通過現場施工(gong)以認證(zheng)了金屬波紋涵(han)管的優越性(xing)和(he)施工(gong)性(xing)。
鋼波(bo)紋(wen)涵(han)管的工(gong)藝要求(qiu)你(ni)知道幾點(dian)?
鋼(gang)(gang)波(bo)(bo)紋涵管的正(zheng)常(chang)使用(yong)溫(wen)度在150℃以內,嚴禁用(yong)氣割(ge)或(huo)電焊破壞鋼(gang)(gang)波(bo)(bo)紋涵管表層及基體。鋼(gang)(gang)波(bo)(bo)紋涵管雖(sui)然屬于免(mian)維護產品,但一般每(mei)半年要進行(xing)(xing)一次(ci)檢查,發現外(wai)表變形、異常(chang)、防(fang)護層脫落等,要隨時(shi)進行(xing)(xing)處理。如果出現較大質量問(wen)題,要立即通知前來處理;
鐵路鋼波紋管
鋼波(bo)(bo)(bo)(bo)紋(wen)(wen)涵(han)管使(shi)(shi)用(yong)年(nian)限(xian)超(chao)過10年(nian)以上,如果表面防(fang)護(hu)層(ceng)出(chu)現大面積(ji)破損,為延長使(shi)(shi)用(yong)壽(shou)命,可自行(xing)進(jin)行(xing)石油(you)瀝青漆防(fang)護(hu)處理(li),也(ye)可聯系(xi)生產(chan)廠(chang)商對(dui)鋼波(bo)(bo)(bo)(bo)紋(wen)(wen)涵(han)管表面整(zheng)體進(jin)行(xing)防(fang)護(hu)處理(li);波(bo)(bo)(bo)(bo)紋(wen)(wen)管涵(han)的(de)長處:鋼波(bo)(bo)(bo)(bo)紋(wen)(wen)涵(han)管工(gong)(gong)廠(chang)生產(chan)時間短(duan)、安(an)裝方(fang)便快捷(jie)、施(shi)工(gong)(gong)工(gong)(gong)期短(duan)、節約施(shi)工(gong)(gong)費(fei)、耐久性、維護(hu)費(fei)用(yong)低、利(li)于環保。涵(han)管、波(bo)(bo)(bo)(bo)紋(wen)(wen)管涵(han)、鋼制波(bo)(bo)(bo)(bo)紋(wen)(wen)管涵(han)洞、金屬波(bo)(bo)(bo)(bo)紋(wen)(wen)涵(han)管在場(chang)安(an)裝便捷(jie),不需(xu)運用(yong)大型設(she)施(shi)。
不(bu)(bu)承擔鋼(gang)波(bo)紋(wen)(wen)涵(han)管(guan)(guan)(guan)因超承載符(fu)合作用下(xia)的變形及失效損失;鋼(gang)波(bo)紋(wen)(wen)涵(han)管(guan)(guan)(guan)的使用注意事(shi)項:施行工(gong)廠集中化出產,出產不(bu)(bu)受(shou)背景影響,有幫(bang)助減低成本、扼(e)制品質。就青藏公路來說(shuo),每道波(bo)紋(wen)(wen)管(guan)(guan)(guan)涵(han)工(gong)程(cheng)造(zao)價比同(tong)樣孔徑的鋼(gang)筋混凝土蓋板涵(han)低4萬(wan)多元。(hanihanbj.com)
