大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼裝支架(jia):搭(da)(da)設腳手(shou)架(jia)根據(ju)波紋(wen)管(guan)的(de)直(zhi)徑(jing)提前確(que)定(ding)，采用管(guan)扣(kou)連接鋼管(guan)的(de)方式(shi)搭(da)(da)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、高為2d3(d為波紋(wen)管(guan)直(zhi)徑(jing))，B型腳手(shou)架(jia)一般(ban)克為25m高依(yi)據(ju)波紋(wen)管(guan)直(zhi)徑(jing)大小拼裝接縫位(wei)置確(que)定(ding)尺寸。腳手(shou)架(jia)按上述尺寸搭(da)(da)設便于施(shi)工、

2、拼裝類型與搭(da)接(jie)方式：拼裝以中心軸線(xian)為基準，由中心向兩(liang)端對稱進行安(an)裝，直至兩(liang)端。1斷面(mian)(奇數斷面(mian))、Ⅱ斷面(mian)(偶數斷面(mian))、加強(qiang)斷面(mian)(偶數斷管管片）

3、波紋(wen)管(guan)拼(pin)裝(zhuang)(zhuang)：采用(yong)刻槽法(fa)施(shi)工的(de)地基(ji)，安(an)裝(zhuang)(zhuang)吊(diao)車(che)依據刻槽深度，依次安(an)裝(zhuang)(zhuang)底部管(guan)片。底部管(guan)片安(an)裝(zhuang)(zhuang)完(wan)成后對剩余管(guan)片進(jin)行安(an)裝(zhuang)(zhuang)。管(guan)片安(an)裝(zhuang)(zhuang)同平基(ji)上的(de)鋼波紋(wen)管(guan)施(shi)工。

4、加強斷面拼裝

當波紋管涵(han)直徑較(jiao)大、填土高度較(jiao)高時，必須(xu)設置加(jia)強管片(pian)，稱(cheng)為(wei)加(jia)強圈”，加(jia)強斷面的(de)管片(pian)安裝工序。
