由于波(bo)紋管帶波(bo)紋,和混(hun)凝(ning)(ning)土分離較好,且鋼(gang)絞線張(zhang)拉灌漿(jiang)凝(ning)(ning)結后可以(yi)讓鋼(gang)絞線、水泥漿(jiang)、梁(liang)板三者之(zhi)間很好的分離,確保張(zhang)拉應力(li)(li)的平均(jun)散布及應力(li)(li)損失。地腳螺栓預(yu)留孔用金屬鋼(gang)波(bo)紋涵管;建(jian)筑、構筑墻體、根底管線預(yu)埋管。
由于(yu)鋼波紋(wen)(wen)涵(han)(han)(han)(han)管(guan)施(shi)工(gong)簡單(dan)且施(shi)工(gong)工(gong)期(qi)短(普通(tong)一(yi)道涵(han)(han)(han)(han)洞的施(shi)工(gong)時間大約在10天-15天左右)縮短了多年凍土的暴(bao)露時間,凍融(rong)量小,故特別適用(yong)于(yu)多年凍土地域。鋼波紋(wen)(wen)涵(han)(han)(han)(han)管(guan)施(shi)工(gong)時對(dui)四周環(huan)境的毀壞小,適用(yong)于(yu)生態環(huan)境脆(cui)弱(ruo)的地域鋼波紋(wen)(wen)涵(han)(han)(han)(han)管(guan)施(shi)工(gong)中(zhong)只需求對(dui)根底(di)停止砂(sha)(sha)礫回填處置(zhi)(zhi),對(dui)進出口停止混凝土或砌(qi)石(shi)施(shi)工(gong)處置(zhi)(zhi),對(dui)砂(sha)(sha)、石(shi)材、鋼筋等(deng)用(yong)量小,十分適用(yong)于(yu)砂(sha)(sha)石(shi)缺乏的地域。
這種方式(shi)都可(ke)以抵(di)達供暖管道(dao)(dao)(dao)防銹(xiu)(xiu)(xiu)處(chu)置的(de)目地。金屬(shu)資(zi)(zi)料(liao)外(wai)表依據防銹(xiu)(xiu)(xiu)處(chu)置處(chu)理(li)后,應(ying)展(zhan)示(shi)出勻稱互相的(de)金屬(shu)質感,不應(ying)該有金屬(shu)資(zi)(zi)料(liao)空氣氧化或許其他防銹(xiu)(xiu)(xiu)處(chu)置是(shi)對金屬(shu)資(zi)(zi)料(liao)鋼波紋(wen)涵管管道(dao)(dao)(dao)在刷(shua)涂防腐資(zi)(zi)料(liao)前展(zhan)開處(chu)理(li)的(de)一道(dao)(dao)(dao)關鍵工作,如今是(shi)肅清(qing)管道(dao)(dao)(dao)外(wai)表的(de)浮塵(chen)、污漬(zi)、銹(xiu)(xiu)(xiu)跡、焊穿(chuan)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/
