由于波(bo)(bo)紋管帶波(bo)(bo)紋,和混凝(ning)土(tu)分離較好(hao),且鋼絞線(xian)張拉灌漿凝(ning)結后可以讓鋼絞線(xian)、水泥漿、梁板三(san)者之間很好(hao)的分離,確保張拉應力的平均散布及應力損失(shi)。地腳(jiao)螺(luo)栓預(yu)留孔用金屬(shu)鋼波(bo)(bo)紋涵(han)管;建筑、構筑墻(qiang)體、根底管線(xian)預(yu)埋管。

由(you)于(yu)鋼(gang)波(bo)(bo)紋(wen)涵管(guan)施工(gong)(gong)簡單且施工(gong)(gong)工(gong)(gong)期短(普通一道涵洞的施工(gong)(gong)時間(jian)大約在10天-15天左(zuo)右)縮短了多(duo)年(nian)凍(dong)(dong)土(tu)的暴露時間(jian),凍(dong)(dong)融量(liang)小,故(gu)特別適(shi)用(yong)(yong)于(yu)多(duo)年(nian)凍(dong)(dong)土(tu)地域。鋼(gang)波(bo)(bo)紋(wen)涵管(guan)施工(gong)(gong)時對(dui)四周環境(jing)的毀壞小,適(shi)用(yong)(yong)于(yu)生態環境(jing)脆弱的地域鋼(gang)波(bo)(bo)紋(wen)涵管(guan)施工(gong)(gong)中只需求對(dui)根(gen)底停止砂(sha)(sha)礫回填處置,對(dui)進出(chu)口停止混(hun)凝土(tu)或砌石(shi)施工(gong)(gong)處置,對(dui)砂(sha)(sha)、石(shi)材、鋼(gang)筋等用(yong)(yong)量(liang)小,十分適(shi)用(yong)(yong)于(yu)砂(sha)(sha)石(shi)缺乏的地域。

這種方(fang)式都可以抵(di)達供暖(nuan)管道(dao)(dao)防銹處置的目地。金(jin)屬資(zi)(zi)料(liao)外表依據防銹處置處理后,應展(zhan)示(shi)出勻稱互(hu)相(xiang)的金(jin)屬質感,不應該有金(jin)屬資(zi)(zi)料(liao)空氣氧(yang)化或許其他防銹處置是對金(jin)屬資(zi)(zi)料(liao)鋼波紋涵管管道(dao)(dao)在刷涂防腐資(zi)(zi)料(liao)前展(zhan)開處理的一道(dao)(dao)關鍵工作,如今是肅清(qing)管道(dao)(dao)外表的浮塵、污(wu)漬(zi)、銹跡、焊穿等(deng)殘(can)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/
