大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼裝(zhuang)支架:搭(da)設腳手(shou)架根據(ju)波(bo)紋(wen)管的(de)直徑提前確(que)定(ding)，采用管扣連接鋼管的(de)方式(shi)搭(da)設腳手(shou)架，形式(shi)分(fen)A型(xing)和(he)B型(xing)腳手(shou)架長(chang)度一(yi)般長(chang)25m、克0、6m、高為2d3(d為波(bo)紋(wen)管直徑)，B型(xing)腳手(shou)架一(yi)般克為25m高依據(ju)波(bo)紋(wen)管直徑大小拼裝(zhuang)接縫位置確(que)定(ding)尺(chi)寸。腳手(shou)架按上(shang)述尺(chi)寸搭(da)設便于施工、

2、拼裝類型與搭(da)接方(fang)式：拼裝以中(zhong)心軸(zhou)線(xian)為基(ji)準，由中(zhong)心向兩(liang)(liang)端對稱進行安裝，直至兩(liang)(liang)端。1斷(duan)(duan)面(mian)(奇數斷(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)面(mian)(偶數斷(duan)(duan)面(mian))、加強斷(duan)(duan)面(mian)(偶數斷(duan)(duan)管(guan)管(guan)片(pian)）

3、波紋(wen)管(guan)拼裝(zhuang)(zhuang)：采用(yong)刻槽法施工的地(di)基(ji)，安(an)裝(zhuang)(zhuang)吊車依(yi)據(ju)刻槽深(shen)度，依(yi)次安(an)裝(zhuang)(zhuang)底(di)部(bu)管(guan)片。底(di)部(bu)管(guan)片安(an)裝(zhuang)(zhuang)完成后對剩余管(guan)片進(jin)行安(an)裝(zhuang)(zhuang)。管(guan)片安(an)裝(zhuang)(zhuang)同平基(ji)上(shang)的鋼波紋(wen)管(guan)施工。

4、加強斷面拼裝

當波紋管(guan)涵直徑較大、填土(tu)高度較高時，必須設置加(jia)(jia)強(qiang)(qiang)管(guan)片，稱為加(jia)(jia)強(qiang)(qiang)圈”，加(jia)(jia)強(qiang)(qiang)斷(duan)面(mian)的管(guan)片安(an)裝工序。
