由于波紋(wen)(wen)管(guan)帶波紋(wen)(wen),和混凝土分離(li)較好(hao),且鋼絞線(xian)張拉灌漿凝結(jie)后(hou)可以讓鋼絞線(xian)、水泥漿、梁板三者之(zhi)間很好(hao)的分離(li),確保(bao)張拉應力的平均散(san)布及應力損失(shi)。地腳螺(luo)栓(shuan)預(yu)留孔用金屬鋼波紋(wen)(wen)涵管(guan);建筑、構筑墻體、根底(di)管(guan)線(xian)預(yu)埋(mai)管(guan)。

由于(yu)鋼(gang)波(bo)紋(wen)(wen)(wen)涵(han)(han)管(guan)施工(gong)(gong)簡單且施工(gong)(gong)工(gong)(gong)期短(duan)(普通一道(dao)涵(han)(han)洞的施工(gong)(gong)時間大(da)約在(zai)10天-15天左右)縮短(duan)了多(duo)年凍土的暴露時間,凍融量小,故特別(bie)適(shi)(shi)(shi)用(yong)于(yu)多(duo)年凍土地(di)域(yu)。鋼(gang)波(bo)紋(wen)(wen)(wen)涵(han)(han)管(guan)施工(gong)(gong)時對(dui)四周(zhou)環(huan)境(jing)的毀壞小,適(shi)(shi)(shi)用(yong)于(yu)生態環(huan)境(jing)脆弱的地(di)域(yu)鋼(gang)波(bo)紋(wen)(wen)(wen)涵(han)(han)管(guan)施工(gong)(gong)中只需(xu)求對(dui)根底停(ting)止砂(sha)礫(li)回填處(chu)置,對(dui)進(jin)出口停(ting)止混凝土或砌石(shi)施工(gong)(gong)處(chu)置,對(dui)砂(sha)、石(shi)材、鋼(gang)筋等用(yong)量小,十分適(shi)(shi)(shi)用(yong)于(yu)砂(sha)石(shi)缺乏的地(di)域(yu)。

這(zhe)種方式都可(ke)以抵達(da)供暖管(guan)(guan)道防(fang)銹處(chu)置(zhi)的目地(di)。金(jin)屬資料(liao)外表(biao)(biao)依據防(fang)銹處(chu)置(zhi)處(chu)理后,應展示出勻稱互相的金(jin)屬質感,不應該有金(jin)屬資料(liao)空氣(qi)氧化或許其(qi)他防(fang)銹處(chu)置(zhi)是(shi)對金(jin)屬資料(liao)鋼波(bo)紋涵管(guan)(guan)管(guan)(guan)道在刷涂(tu)防(fang)腐(fu)資料(liao)前展開處(chu)理的一道關(guan)鍵(jian)工(gong)作(zuo),如(ru)今是(shi)肅清管(guan)(guan)道外表(biao)(biao)的浮塵(chen)、污(wu)漬、銹跡、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/
