大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼(pin)裝支架:搭(da)設(she)腳(jiao)手(shou)架根據波(bo)紋管(guan)的直徑(jing)提前確定，采用管(guan)扣連接鋼(gang)管(guan)的方式(shi)搭(da)設(she)腳(jiao)手(shou)架，形式(shi)分A型和B型腳(jiao)手(shou)架長(chang)度一般(ban)長(chang)25m、克0、6m、高(gao)為2d3(d為波(bo)紋管(guan)直徑(jing))，B型腳(jiao)手(shou)架一般(ban)克為25m高(gao)依據波(bo)紋管(guan)直徑(jing)大小拼(pin)裝接縫位置確定尺寸。腳(jiao)手(shou)架按上述尺寸搭(da)設(she)便于施工、

2、拼(pin)裝(zhuang)類型與搭接(jie)方(fang)式：拼(pin)裝(zhuang)以中(zhong)心軸線為(wei)基準，由(you)中(zhong)心向(xiang)兩端(duan)對稱進行安(an)裝(zhuang)，直至兩端(duan)。1斷(duan)(duan)面(mian)(mian)(奇數(shu)斷(duan)(duan)面(mian)(mian))、Ⅱ斷(duan)(duan)面(mian)(mian)(偶(ou)數(shu)斷(duan)(duan)面(mian)(mian))、加強斷(duan)(duan)面(mian)(mian)(偶(ou)數(shu)斷(duan)(duan)管管片）

3、波紋(wen)管(guan)拼裝(zhuang)(zhuang)：采用(yong)刻槽法(fa)施(shi)工的(de)地基，安(an)裝(zhuang)(zhuang)吊車依據刻槽深度，依次安(an)裝(zhuang)(zhuang)底部管(guan)片(pian)。底部管(guan)片(pian)安(an)裝(zhuang)(zhuang)完成后對剩余管(guan)片(pian)進行安(an)裝(zhuang)(zhuang)。管(guan)片(pian)安(an)裝(zhuang)(zhuang)同(tong)平(ping)基上(shang)的(de)鋼波紋(wen)管(guan)施(shi)工。
