大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝支架(jia)(jia)(jia):搭設(she)腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)根據波紋管(guan)的(de)直(zhi)(zhi)徑提前確定，采用管(guan)扣連接鋼管(guan)的(de)方式(shi)搭設(she)腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)，形式(shi)分A型(xing)(xing)和B型(xing)(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)長度一(yi)般(ban)長25m、克0、6m、高(gao)為(wei)2d3(d為(wei)波紋管(guan)直(zhi)(zhi)徑)，B型(xing)(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)一(yi)般(ban)克為(wei)25m高(gao)依(yi)據波紋管(guan)直(zhi)(zhi)徑大(da)小拼裝接縫位置確定尺(chi)寸(cun)。腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)按上述尺(chi)寸(cun)搭設(she)便(bian)于施工、

2、拼(pin)裝類型與搭接方式：拼(pin)裝以中(zhong)心軸線為基(ji)準，由中(zhong)心向兩端對稱進行安裝，直至(zhi)兩端。1斷(duan)面(mian)(奇數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶(ou)數斷(duan)面(mian))、加強斷(duan)面(mian)(偶(ou)數斷(duan)管(guan)管(guan)片）

3、波紋管(guan)(guan)拼裝(zhuang)：采用刻槽(cao)法施(shi)工(gong)的(de)地(di)基(ji)，安(an)(an)裝(zhuang)吊車依(yi)(yi)據刻槽(cao)深度，依(yi)(yi)次安(an)(an)裝(zhuang)底部管(guan)(guan)片(pian)。底部管(guan)(guan)片(pian)安(an)(an)裝(zhuang)完(wan)成后(hou)對剩余管(guan)(guan)片(pian)進行安(an)(an)裝(zhuang)。管(guan)(guan)片(pian)安(an)(an)裝(zhuang)同平基(ji)上的(de)鋼波紋管(guan)(guan)施(shi)工(gong)。
