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)(jia):搭(da)(da)設腳手架(jia)(jia)根據波紋管(guan)(guan)的直(zhi)徑提前確(que)定(ding)，采用管(guan)(guan)扣連接鋼管(guan)(guan)的方式(shi)搭(da)(da)設腳手架(jia)(jia)，形式(shi)分A型和B型腳手架(jia)(jia)長(chang)度一(yi)般長(chang)25m、克0、6m、高為2d3(d為波紋管(guan)(guan)直(zhi)徑)，B型腳手架(jia)(jia)一(yi)般克為25m高依據波紋管(guan)(guan)直(zhi)徑大小拼裝接縫位置確(que)定(ding)尺寸。腳手架(jia)(jia)按上(shang)述尺寸搭(da)(da)設便于(yu)施工、

2、拼(pin)裝(zhuang)類型與搭接(jie)方式：拼(pin)裝(zhuang)以中心軸線為基準，由中心向兩(liang)端對稱(cheng)進行(xing)安裝(zhuang)，直至兩(liang)端。1斷(duan)面(mian)(奇數(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數(shu)斷(duan)面(mian))、加(jia)強(qiang)斷(duan)面(mian)(偶數(shu)斷(duan)管管片）

3、波(bo)紋管(guan)拼裝(zhuang)(zhuang)：采用刻槽法施工的地(di)基，安(an)裝(zhuang)(zhuang)吊車(che)依據刻槽深度，依次安(an)裝(zhuang)(zhuang)底(di)部(bu)管(guan)片(pian)。底(di)部(bu)管(guan)片(pian)安(an)裝(zhuang)(zhuang)完成后(hou)對剩余管(guan)片(pian)進行安(an)裝(zhuang)(zhuang)。管(guan)片(pian)安(an)裝(zhuang)(zhuang)同(tong)平基上的鋼波(bo)紋管(guan)施工。

4、加強斷面拼裝

當波(bo)紋管涵直徑較(jiao)大、填土高度較(jiao)高時，必須(xu)設置(zhi)加強(qiang)管片，稱為(wei)加強(qiang)圈(quan)”，加強(qiang)斷面的管片安裝(zhuang)工序。
