大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝支架(jia)(jia):搭設腳手(shou)架(jia)(jia)根(gen)據(ju)波紋管(guan)的直(zhi)徑提(ti)前(qian)確定，采用(yong)管(guan)扣連(lian)接(jie)鋼(gang)管(guan)的方式搭設腳手(shou)架(jia)(jia)，形式分A型和B型腳手(shou)架(jia)(jia)長度一(yi)般長25m、克0、6m、高(gao)(gao)為2d3(d為波紋管(guan)直(zhi)徑)，B型腳手(shou)架(jia)(jia)一(yi)般克為25m高(gao)(gao)依(yi)據(ju)波紋管(guan)直(zhi)徑大(da)小(xiao)拼裝接(jie)縫位置確定尺寸。腳手(shou)架(jia)(jia)按(an)上述尺寸搭設便于(yu)施工、

2、拼裝(zhuang)類型與搭接方式：拼裝(zhuang)以中心軸線(xian)為基準，由(you)中心向兩(liang)端對稱進行安裝(zhuang)，直(zhi)至兩(liang)端。1斷(duan)面(mian)(奇數(shu)(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數(shu)(shu)斷(duan)面(mian))、加強斷(duan)面(mian)(偶數(shu)(shu)斷(duan)管(guan)管(guan)片(pian)）

3、波紋管(guan)拼裝(zhuang)：采用刻槽法施工的地基，安裝(zhuang)吊車依據刻槽深度，依次安裝(zhuang)底部管(guan)片。底部管(guan)片安裝(zhuang)完(wan)成后對剩余(yu)管(guan)片進行安裝(zhuang)。管(guan)片安裝(zhuang)同平(ping)基上(shang)的鋼波紋管(guan)施工。

4、加強斷面拼裝

當波紋管涵直徑較(jiao)(jiao)大、填土(tu)高(gao)度較(jiao)(jiao)高(gao)時，必須設置加(jia)(jia)強(qiang)(qiang)管片(pian)(pian)，稱為加(jia)(jia)強(qiang)(qiang)圈”，加(jia)(jia)強(qiang)(qiang)斷面(mian)的(de)管片(pian)(pian)安裝工(gong)序。
