由于(yu)波紋(wen)(wen)管(guan)帶波紋(wen)(wen),和混(hun)凝土分離較好,且鋼絞線張拉灌漿(jiang)凝結(jie)后(hou)可以讓(rang)鋼絞線、水泥漿(jiang)、梁板三者之間(jian)很好的(de)分離,確保張拉應力的(de)平(ping)均(jun)散布(bu)及應力損失。地腳螺栓預(yu)留孔(kong)用金屬鋼波紋(wen)(wen)涵管(guan);建筑、構筑墻體、根(gen)底管(guan)線預(yu)埋管(guan)。

這種方式都(dou)可(ke)以抵(di)達供(gong)暖(nuan)管(guan)(guan)道(dao)防(fang)(fang)銹(xiu)處(chu)置(zhi)的目地。金(jin)(jin)屬(shu)(shu)資料(liao)外表依據防(fang)(fang)銹(xiu)處(chu)置(zhi)處(chu)理后(hou),應(ying)展示出勻稱互相的金(jin)(jin)屬(shu)(shu)質感,不(bu)應(ying)該有金(jin)(jin)屬(shu)(shu)資料(liao)空氣氧(yang)化(hua)或(huo)許(xu)其(qi)他(ta)防(fang)(fang)銹(xiu)處(chu)置(zhi)是(shi)對金(jin)(jin)屬(shu)(shu)資料(liao)鋼波紋涵管(guan)(guan)管(guan)(guan)道(dao)在刷涂(tu)防(fang)(fang)腐資料(liao)前展開處(chu)理的一道(dao)關鍵工作,如(ru)今是(shi)肅清管(guan)(guan)道(dao)外表的浮塵、污(wu)漬、銹(xiu)跡、焊穿等殘物。

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/
