大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝(zhuang)支架(jia):搭(da)設(she)腳手(shou)(shou)架(jia)根據(ju)波(bo)(bo)紋管的直(zhi)徑(jing)(jing)提前確定(ding)，采用管扣(kou)連接鋼管的方式搭(da)設(she)腳手(shou)(shou)架(jia)，形式分A型(xing)和B型(xing)腳手(shou)(shou)架(jia)長(chang)度一般長(chang)25m、克0、6m、高(gao)為(wei)2d3(d為(wei)波(bo)(bo)紋管直(zhi)徑(jing)(jing))，B型(xing)腳手(shou)(shou)架(jia)一般克為(wei)25m高(gao)依(yi)據(ju)波(bo)(bo)紋管直(zhi)徑(jing)(jing)大小拼裝(zhuang)接縫(feng)位置確定(ding)尺(chi)寸。腳手(shou)(shou)架(jia)按上述尺(chi)寸搭(da)設(she)便于施工、

2、拼(pin)裝類型(xing)與搭接(jie)方式：拼(pin)裝以中心軸(zhou)線(xian)為基準(zhun)，由中心向兩端對稱進行安裝，直至(zhi)兩端。1斷面(mian)(奇數(shu)斷面(mian))、Ⅱ斷面(mian)(偶數(shu)斷面(mian))、加強斷面(mian)(偶數(shu)斷管管片）

3、波(bo)紋管(guan)(guan)拼裝(zhuang)(zhuang)：采用刻(ke)槽法施工(gong)的地基，安(an)(an)裝(zhuang)(zhuang)吊車依據刻(ke)槽深度，依次安(an)(an)裝(zhuang)(zhuang)底部管(guan)(guan)片(pian)(pian)。底部管(guan)(guan)片(pian)(pian)安(an)(an)裝(zhuang)(zhuang)完(wan)成后對剩(sheng)余管(guan)(guan)片(pian)(pian)進行安(an)(an)裝(zhuang)(zhuang)。管(guan)(guan)片(pian)(pian)安(an)(an)裝(zhuang)(zhuang)同平基上的鋼波(bo)紋管(guan)(guan)施工(gong)。
