鋼波紋管的資(zi)料(liao)普通為青(qing)銅(tong)、黃銅(tong)、不銹鋼(gang)、蒙乃爾(er)合金和因康鎳爾(er)合金等。鋼(gang)波紋(wen)管選用規(gui)范(fan)化(hua)設計方案,出(chu)產制造,設計方案簡易,出(chu)產制造周期時(shi)間短;工(gong)(gong)(gong)程(cheng)項(xiang)目細(xi)致工(gong)(gong)(gong)程(cheng)造價比類似跨(kua)距的橋,洞低;工(gong)(gong)(gong)程(cheng)施(shi)(shi)工(gong)(gong)(gong)短工(gong)(gong)(gong)期,關鍵為組裝工(gong)(gong)(gong)程(cheng)施(shi)(shi)工(gong)(gong)(gong)。
金(jin)屬(shu)資料(liao)鋼(gang)波紋(wen)(wen)管替代混凝土結構(gou)展開洞工程施工。具(ju)有較大的(de)抗變形和(he)抗沉(chen)降才干,施工過程中重量輕、設備便(bian)當快捷、施工簡約等許多優點。鋼(gang)波紋(wen)(wen)管按構(gou)成(cheng)資料(liao)可分為金(jin)屬(shu)波紋(wen)(wen)管、非金(jin)屬(shu)波紋(wen)(wen)管兩(liang)種。
按構造(zao)可(ke)分為單層(ceng)和多(duo)(duo)層(ceng),單層(ceng)波紋(wen)管(guan)(guan)應用(yong)較多(duo)(duo)。多(duo)(duo)層(ceng)波紋(wen)管(guan)(guan)強(qiang)(qiang)度高(gao),耐(nai)久性好,應力小,用(yong)在(zai)重要的丈量中(zhong)。鋼(gang)波紋(wen)管(guan)(guan)具有施工(gong)工(gong)期短、重量輕、安裝便當、耐(nai)久性能(neng)好、工(gong)程造(zao)價(jia)低、抗變形(xing)才干強(qiang)(qiang)、減少維(wei)護費用(yong)本錢等優點。鋼(gang)波紋(wen)管(guan)(guan)是一種柔性構造(zao),波紋(wen)管(guan)(guan)在(zai)構造(zao)上具有橫(heng)向賠償位移特性,可(ke)充分發揮鋼(gang)材抗拉功用(yong)強(qiang)(qiang)。
一、鋼波紋(wen)管(guan)涵的外(wai)側(ce)主要(yao)是(shi)土壤腐蝕(shi),而內側(ce)主要(yao)是(shi)水腐蝕(shi)和大氣腐蝕(shi),著重是(shi)土壤腐蝕(shi)和水腐蝕(shi)防(fang)護。
二、在設(she)計(ji)階(jie)段選(xuan)擇資料時,應思索特定介質中的材料、數據(ju)和腐(fu)蝕特性,并應用有效(xiao)的工(gong)作閱歷和程序。
三、防腐設計應遵照預防與維護相別離的準繩,根據消費過程中產生的介質腐蝕情況、環境條件、消費運轉管理水平和施工維護條件,量體裁衣,區別對待,綜合選擇防腐措施。危及人身平安。//hanihanbj.com/
