大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼(pin)裝支架(jia)(jia)(jia):搭(da)設(she)腳手架(jia)(jia)(jia)根據波(bo)紋(wen)(wen)管(guan)(guan)的(de)直徑提前確(que)(que)定，采用管(guan)(guan)扣連接鋼管(guan)(guan)的(de)方式(shi)搭(da)設(she)腳手架(jia)(jia)(jia)，形式(shi)分A型和B型腳手架(jia)(jia)(jia)長度一般長25m、克(ke)0、6m、高(gao)為2d3(d為波(bo)紋(wen)(wen)管(guan)(guan)直徑)，B型腳手架(jia)(jia)(jia)一般克(ke)為25m高(gao)依(yi)據波(bo)紋(wen)(wen)管(guan)(guan)直徑大小拼(pin)裝接縫位置確(que)(que)定尺寸。腳手架(jia)(jia)(jia)按上述尺寸搭(da)設(she)便于施工、

2、拼裝類型與搭接方式：拼裝以中(zhong)心(xin)軸線(xian)為基準，由中(zhong)心(xin)向(xiang)兩端對稱(cheng)進(jin)行安裝，直至兩端。1斷(duan)面(mian)(mian)(奇數斷(duan)面(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(偶數斷(duan)面(mian)(mian))、加強斷(duan)面(mian)(mian)(偶數斷(duan)管管片(pian)）

3、波紋管(guan)拼裝(zhuang)(zhuang)：采用刻槽(cao)法施(shi)(shi)工的地基(ji)(ji)，安(an)裝(zhuang)(zhuang)吊車依(yi)據刻槽(cao)深度(du)，依(yi)次(ci)安(an)裝(zhuang)(zhuang)底(di)部管(guan)片(pian)。底(di)部管(guan)片(pian)安(an)裝(zhuang)(zhuang)完成后對剩余管(guan)片(pian)進(jin)行安(an)裝(zhuang)(zhuang)。管(guan)片(pian)安(an)裝(zhuang)(zhuang)同(tong)平基(ji)(ji)上(shang)的鋼波紋管(guan)施(shi)(shi)工。

4、加強斷面拼裝

當(dang)波紋管(guan)涵直徑較大、填土(tu)高度較高時，必須設置加強(qiang)管(guan)片(pian)，稱為加強(qiang)圈(quan)”，加強(qiang)斷(duan)面的管(guan)片(pian)安裝工序。
