由于波(bo)紋(wen)(wen)管帶波(bo)紋(wen)(wen),和混(hun)凝土分(fen)離(li)較(jiao)好,且鋼(gang)(gang)絞(jiao)線(xian)張(zhang)(zhang)拉灌漿凝結后(hou)可以(yi)讓鋼(gang)(gang)絞(jiao)線(xian)、水泥漿、梁板三者(zhe)之(zhi)間很好的分(fen)離(li),確保張(zhang)(zhang)拉應力的平均散(san)布及應力損失。地腳螺(luo)栓預留孔用金(jin)屬鋼(gang)(gang)波(bo)紋(wen)(wen)涵(han)管;建筑、構筑墻體、根(gen)底管線(xian)預埋管。
由于(yu)鋼波(bo)紋涵(han)管施(shi)工(gong)(gong)簡單且(qie)施(shi)工(gong)(gong)工(gong)(gong)期短(普通一道涵(han)洞的施(shi)工(gong)(gong)時(shi)間大約在(zai)10天(tian)-15天(tian)左右)縮短了多年凍土(tu)的暴露時(shi)間,凍融量(liang)小,故特別(bie)適用(yong)(yong)(yong)于(yu)多年凍土(tu)地域。鋼波(bo)紋涵(han)管施(shi)工(gong)(gong)時(shi)對四周環(huan)境的毀(hui)壞(huai)小,適用(yong)(yong)(yong)于(yu)生態環(huan)境脆弱的地域鋼波(bo)紋涵(han)管施(shi)工(gong)(gong)中只需求對根底停止砂礫回填處置,對進出口停止混凝土(tu)或砌(qi)石施(shi)工(gong)(gong)處置,對砂、石材、鋼筋(jin)等用(yong)(yong)(yong)量(liang)小,十(shi)分適用(yong)(yong)(yong)于(yu)砂石缺乏的地域。
這種(zhong)方式都可以抵達供暖管道防(fang)(fang)銹(xiu)處置(zhi)的(de)目地(di)。金(jin)屬資料(liao)外(wai)表依據防(fang)(fang)銹(xiu)處置(zhi)處理后,應(ying)展示出勻(yun)稱互相的(de)金(jin)屬質感,不應(ying)該(gai)有(you)金(jin)屬資料(liao)空氣氧化或許其(qi)他防(fang)(fang)銹(xiu)處置(zhi)是(shi)對(dui)金(jin)屬資料(liao)鋼波紋涵管管道在刷(shua)涂防(fang)(fang)腐(fu)資料(liao)前(qian)展開處理的(de)一道關鍵工(gong)作,如今是(shi)肅清管道外(wai)表的(de)浮塵、污(wu)漬、銹(xiu)跡、焊穿等(deng)殘物。
鋼波紋涵管施工時,采用分段施工的辦法,預先在原拱涵基底用角鋼并排兩根,長度依據涵長肯定,作涵管推進時的滑軌,鋼波紋涵管管徑依據工程需求可有不同的規格,整裝管管徑為0.5m-2.5m,每節長度3.06米,采用內(外)法蘭螺栓銜接,拼裝管管徑為3m-8m,板與板搭接高強螺栓緊固。//hanihanbj.com/
