由于(yu)波紋管(guan)帶(dai)波紋,和混凝土分離較好(hao),且鋼(gang)絞線張拉灌漿(jiang)凝結后可(ke)以(yi)讓(rang)鋼(gang)絞線、水泥(ni)漿(jiang)、梁(liang)板三者之間很好(hao)的(de)分離,確保張拉應(ying)力的(de)平均散(san)布及應(ying)力損失。地腳螺栓預留孔用金屬鋼(gang)波紋涵管(guan);建筑、構筑墻體(ti)、根底管(guan)線預埋管(guan)。
由于(yu)鋼(gang)波紋(wen)涵(han)管施(shi)工(gong)(gong)(gong)簡單(dan)且施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)期短(duan)(普通(tong)一(yi)道涵(han)洞(dong)的施(shi)工(gong)(gong)(gong)時間大約(yue)在10天(tian)-15天(tian)左(zuo)右)縮短(duan)了(le)多年凍土的暴露時間,凍融量(liang)小(xiao),故(gu)特別適(shi)用(yong)于(yu)多年凍土地域。鋼(gang)波紋(wen)涵(han)管施(shi)工(gong)(gong)(gong)時對四周環(huan)境(jing)的毀壞小(xiao),適(shi)用(yong)于(yu)生態環(huan)境(jing)脆弱的地域鋼(gang)波紋(wen)涵(han)管施(shi)工(gong)(gong)(gong)中只需求對根底停止砂礫回填處置(zhi),對進(jin)出口停止混凝土或砌石(shi)施(shi)工(gong)(gong)(gong)處置(zhi),對砂、石(shi)材(cai)、鋼(gang)筋等用(yong)量(liang)小(xiao),十分適(shi)用(yong)于(yu)砂石(shi)缺(que)乏的地域。
這種方式都可以抵達(da)供暖管(guan)道防銹(xiu)處(chu)置(zhi)的(de)目地。金屬資(zi)(zi)料(liao)(liao)外表(biao)依(yi)據防銹(xiu)處(chu)置(zhi)處(chu)理(li)后,應展示出勻稱互相的(de)金屬質(zhi)感,不應該有金屬資(zi)(zi)料(liao)(liao)空氣氧化或許其他防銹(xiu)處(chu)置(zhi)是對金屬資(zi)(zi)料(liao)(liao)鋼(gang)波紋涵管(guan)管(guan)道在刷涂(tu)防腐資(zi)(zi)料(liao)(liao)前(qian)展開處(chu)理(li)的(de)一道關鍵工(gong)作(zuo),如(ru)今是肅清管(guan)道外表(biao)的(de)浮塵、污漬、銹(xiu)跡、焊穿(chuan)等殘(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/
