1、搭設(she)拼裝(zhuang)(zhuang)支架(jia):搭設(she)腳(jiao)手(shou)架(jia)根(gen)據波(bo)紋(wen)(wen)(wen)管(guan)的直徑提前確定，采用管(guan)扣連接(jie)鋼管(guan)的方式搭設(she)腳(jiao)手(shou)架(jia)，形式分A型(xing)和B型(xing)腳(jiao)手(shou)架(jia)長(chang)度一般長(chang)25m、克(ke)0、6m、高為2d3(d為波(bo)紋(wen)(wen)(wen)管(guan)直徑)，B型(xing)腳(jiao)手(shou)架(jia)一般克(ke)為25m高依據波(bo)紋(wen)(wen)(wen)管(guan)直徑大小拼裝(zhuang)(zhuang)接(jie)縫位置確定尺(chi)寸。腳(jiao)手(shou)架(jia)按(an)上述尺(chi)寸搭設(she)便于施工(gong)、

2、拼裝(zhuang)類型與搭接方式(shi)：拼裝(zhuang)以中(zhong)心(xin)(xin)軸線為基(ji)準，由中(zhong)心(xin)(xin)向兩端對稱進行安(an)裝(zhuang)，直至兩端。1斷(duan)面(奇數(shu)斷(duan)面)、Ⅱ斷(duan)面(偶(ou)數(shu)斷(duan)面)、加強(qiang)斷(duan)面(偶(ou)數(shu)斷(duan)管管片）

3、波紋(wen)管(guan)拼裝：采用刻槽(cao)法施工的(de)地基，安裝吊車(che)依(yi)據刻槽(cao)深(shen)度(du)，依(yi)次安裝底部管(guan)片。底部管(guan)片安裝完(wan)成(cheng)后對剩余管(guan)片進行安裝。管(guan)片安裝同平基上(shang)的(de)鋼波紋(wen)管(guan)施工。

4、加強斷面拼裝

當波(bo)紋管(guan)涵(han)直徑較大、填土高(gao)度較高(gao)時，必須設置加強(qiang)管(guan)片(pian)，稱為加強(qiang)圈”，加強(qiang)斷面(mian)的管(guan)片(pian)安裝(zhuang)工序(xu)。
