大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼(pin)裝支架(jia)(jia):搭(da)設腳手(shou)架(jia)(jia)根據波紋(wen)管(guan)(guan)的(de)直(zhi)徑提前確(que)定(ding)，采(cai)用管(guan)(guan)扣連接(jie)鋼管(guan)(guan)的(de)方式(shi)搭(da)設腳手(shou)架(jia)(jia)，形式(shi)分A型(xing)和B型(xing)腳手(shou)架(jia)(jia)長(chang)度(du)一(yi)般長(chang)25m、克(ke)0、6m、高為(wei)2d3(d為(wei)波紋(wen)管(guan)(guan)直(zhi)徑)，B型(xing)腳手(shou)架(jia)(jia)一(yi)般克(ke)為(wei)25m高依據波紋(wen)管(guan)(guan)直(zhi)徑大小拼(pin)裝接(jie)縫位置確(que)定(ding)尺寸。腳手(shou)架(jia)(jia)按上述尺寸搭(da)設便于施工、

2、拼裝(zhuang)(zhuang)類型與(yu)搭接(jie)方式：拼裝(zhuang)(zhuang)以中心軸線(xian)為(wei)基(ji)準(zhun)，由中心向兩端(duan)對稱進(jin)行安裝(zhuang)(zhuang)，直(zhi)至兩端(duan)。1斷(duan)面(mian)(mian)(奇數(shu)斷(duan)面(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(偶數(shu)斷(duan)面(mian)(mian))、加(jia)強斷(duan)面(mian)(mian)(偶數(shu)斷(duan)管管片）

3、波(bo)紋(wen)管(guan)(guan)(guan)拼裝(zhuang)(zhuang)：采用刻(ke)槽(cao)法施(shi)工(gong)的(de)地基，安(an)(an)裝(zhuang)(zhuang)吊車依(yi)(yi)據刻(ke)槽(cao)深(shen)度，依(yi)(yi)次安(an)(an)裝(zhuang)(zhuang)底(di)部(bu)管(guan)(guan)(guan)片(pian)(pian)(pian)。底(di)部(bu)管(guan)(guan)(guan)片(pian)(pian)(pian)安(an)(an)裝(zhuang)(zhuang)完成(cheng)后對剩余管(guan)(guan)(guan)片(pian)(pian)(pian)進行(xing)安(an)(an)裝(zhuang)(zhuang)。管(guan)(guan)(guan)片(pian)(pian)(pian)安(an)(an)裝(zhuang)(zhuang)同平基上(shang)的(de)鋼(gang)波(bo)紋(wen)管(guan)(guan)(guan)施(shi)工(gong)。
