大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝(zhuang)支架:搭設(she)腳手(shou)(shou)架根據波紋管(guan)的直徑提前確定，采用管(guan)扣連接(jie)鋼管(guan)的方式搭設(she)腳手(shou)(shou)架，形式分A型(xing)和(he)B型(xing)腳手(shou)(shou)架長度一般(ban)長25m、克0、6m、高(gao)為2d3(d為波紋管(guan)直徑)，B型(xing)腳手(shou)(shou)架一般(ban)克為25m高(gao)依據波紋管(guan)直徑大小拼裝(zhuang)接(jie)縫位置(zhi)確定尺(chi)(chi)寸。腳手(shou)(shou)架按上述尺(chi)(chi)寸搭設(she)便(bian)于施工(gong)、

2、拼(pin)裝類型與搭(da)接方(fang)式：拼(pin)裝以中(zhong)心(xin)軸線為基準，由中(zhong)心(xin)向兩(liang)端對稱進行安裝，直至兩(liang)端。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))、加強斷(duan)面(mian)(mian)(偶數(shu)斷(duan)管管片）

3、波紋(wen)管(guan)拼(pin)裝：采用(yong)刻(ke)槽(cao)法施(shi)工的地基，安(an)裝吊車依據刻(ke)槽(cao)深度(du)，依次安(an)裝底部(bu)管(guan)片(pian)。底部(bu)管(guan)片(pian)安(an)裝完成后對(dui)剩余管(guan)片(pian)進行安(an)裝。管(guan)片(pian)安(an)裝同平基上的鋼波紋(wen)管(guan)施(shi)工。

4、加強斷面拼裝

當波紋管涵直徑(jing)較(jiao)大、填土(tu)高度較(jiao)高時，必須設置加強管片(pian)，稱為(wei)加強圈(quan)”，加強斷面的(de)管片(pian)安裝工序。
