大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝支架(jia):搭設腳手(shou)架(jia)根據波(bo)紋(wen)管的直徑(jing)提前確定，采用(yong)管扣連(lian)接鋼管的方式(shi)搭設腳手(shou)架(jia)，形(xing)式(shi)分A型和B型腳手(shou)架(jia)長度一般(ban)長25m、克0、6m、高(gao)為2d3(d為波(bo)紋(wen)管直徑(jing))，B型腳手(shou)架(jia)一般(ban)克為25m高(gao)依據波(bo)紋(wen)管直徑(jing)大(da)小拼裝接縫(feng)位置確定尺寸。腳手(shou)架(jia)按上述尺寸搭設便于施工、

2、拼裝類型與搭接方式：拼裝以中心(xin)軸線(xian)為基準(zhun)，由中心(xin)向兩(liang)(liang)端對稱進行安裝，直至兩(liang)(liang)端。1斷(duan)面(mian)(奇數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數斷(duan)面(mian))、加強斷(duan)面(mian)(偶數斷(duan)管(guan)管(guan)片）

3、波紋管(guan)(guan)拼裝(zhuang)：采用刻槽(cao)法施工的地基，安裝(zhuang)吊車依據刻槽(cao)深度，依次安裝(zhuang)底部管(guan)(guan)片(pian)(pian)(pian)。底部管(guan)(guan)片(pian)(pian)(pian)安裝(zhuang)完(wan)成后對剩余管(guan)(guan)片(pian)(pian)(pian)進行安裝(zhuang)。管(guan)(guan)片(pian)(pian)(pian)安裝(zhuang)同(tong)平基上的鋼波紋管(guan)(guan)施工。

4、加強斷面拼裝

當波紋管涵直(zhi)徑(jing)較大、填土(tu)高度較高時，必須設置加強管片(pian)，稱為加強圈”，加強斷(duan)面的管片(pian)安裝(zhuang)工序。
