大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝(zhuang)支架(jia):搭設腳(jiao)(jiao)手架(jia)根據波(bo)紋(wen)管(guan)的直徑提(ti)前(qian)確定，采用(yong)管(guan)扣連(lian)接(jie)鋼管(guan)的方式搭設腳(jiao)(jiao)手架(jia)，形式分(fen)A型和B型腳(jiao)(jiao)手架(jia)長度一般長25m、克(ke)0、6m、高(gao)為2d3(d為波(bo)紋(wen)管(guan)直徑)，B型腳(jiao)(jiao)手架(jia)一般克(ke)為25m高(gao)依據波(bo)紋(wen)管(guan)直徑大小拼裝(zhuang)接(jie)縫位置(zhi)確定尺寸。腳(jiao)(jiao)手架(jia)按上述尺寸搭設便(bian)于(yu)施工、

2、拼(pin)裝類(lei)型(xing)與搭接方式：拼(pin)裝以中心軸線為基準，由(you)中心向(xiang)兩端(duan)(duan)對稱(cheng)進行安裝，直至兩端(duan)(duan)。1斷(duan)面(mian)(mian)(奇數(shu)斷(duan)面(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(偶(ou)數(shu)斷(duan)面(mian)(mian))、加(jia)強斷(duan)面(mian)(mian)(偶(ou)數(shu)斷(duan)管管片）

3、波(bo)紋(wen)管(guan)(guan)(guan)拼裝(zhuang)(zhuang)(zhuang)(zhuang)：采用刻槽法施(shi)工的地基，安裝(zhuang)(zhuang)(zhuang)(zhuang)吊(diao)車依(yi)據刻槽深度，依(yi)次安裝(zhuang)(zhuang)(zhuang)(zhuang)底(di)部(bu)管(guan)(guan)(guan)片(pian)。底(di)部(bu)管(guan)(guan)(guan)片(pian)安裝(zhuang)(zhuang)(zhuang)(zhuang)完(wan)成后對(dui)剩余(yu)管(guan)(guan)(guan)片(pian)進行安裝(zhuang)(zhuang)(zhuang)(zhuang)。管(guan)(guan)(guan)片(pian)安裝(zhuang)(zhuang)(zhuang)(zhuang)同(tong)平基上(shang)的鋼波(bo)紋(wen)管(guan)(guan)(guan)施(shi)工。
