由于波(bo)紋(wen)(wen)管帶波(bo)紋(wen)(wen),和混凝土分(fen)離較好,且鋼絞線(xian)(xian)張(zhang)拉灌漿(jiang)凝結(jie)后可(ke)以讓鋼絞線(xian)(xian)、水(shui)泥(ni)漿(jiang)、梁板(ban)三者(zhe)之間很好的(de)分(fen)離,確保(bao)張(zhang)拉應(ying)力(li)的(de)平均散布及應(ying)力(li)損失(shi)。地(di)腳螺栓(shuan)預留孔用金屬鋼波(bo)紋(wen)(wen)涵管;建(jian)筑(zhu)、構筑(zhu)墻體、根(gen)底管線(xian)(xian)預埋管。
由于(yu)鋼波紋涵管(guan)施(shi)工(gong)(gong)簡單且(qie)施(shi)工(gong)(gong)工(gong)(gong)期短(普通一道涵洞的(de)(de)施(shi)工(gong)(gong)時間(jian)大約在10天-15天左(zuo)右)縮短了多(duo)年凍土的(de)(de)暴露時間(jian),凍融量(liang)小,故特(te)別適(shi)用于(yu)多(duo)年凍土地(di)域。鋼波紋涵管(guan)施(shi)工(gong)(gong)時對四周環(huan)境(jing)的(de)(de)毀(hui)壞小,適(shi)用于(yu)生態環(huan)境(jing)脆弱的(de)(de)地(di)域鋼波紋涵管(guan)施(shi)工(gong)(gong)中(zhong)只需(xu)求(qiu)對根(gen)底停止(zhi)砂礫回填處置(zhi),對進(jin)出口停止(zhi)混凝土或砌石(shi)(shi)施(shi)工(gong)(gong)處置(zhi),對砂、石(shi)(shi)材、鋼筋等用量(liang)小,十分適(shi)用于(yu)砂石(shi)(shi)缺(que)乏的(de)(de)地(di)域。
這(zhe)種方式都可以抵(di)達(da)供暖管(guan)(guan)道(dao)(dao)防(fang)銹處(chu)(chu)置的目地。金(jin)屬(shu)(shu)(shu)資(zi)料(liao)外表依(yi)據防(fang)銹處(chu)(chu)置處(chu)(chu)理(li)后,應展示出勻稱互相的金(jin)屬(shu)(shu)(shu)質(zhi)感,不(bu)應該有金(jin)屬(shu)(shu)(shu)資(zi)料(liao)空氣氧化(hua)或許其他(ta)防(fang)銹處(chu)(chu)置是對金(jin)屬(shu)(shu)(shu)資(zi)料(liao)鋼波紋涵管(guan)(guan)管(guan)(guan)道(dao)(dao)在刷涂防(fang)腐資(zi)料(liao)前(qian)展開處(chu)(chu)理(li)的一道(dao)(dao)關(guan)鍵(jian)工作(zuo),如今是肅清(qing)管(guan)(guan)道(dao)(dao)外表的浮塵、污漬、銹跡(ji)、焊穿等(deng)殘物(wu)。
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/
