大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝(zhuang)支架(jia):搭(da)設(she)腳(jiao)手架(jia)根據波(bo)紋管(guan)的直徑提前確定(ding)，采用管(guan)扣連接(jie)鋼管(guan)的方式搭(da)設(she)腳(jiao)手架(jia)，形式分A型和B型腳(jiao)手架(jia)長度一(yi)(yi)般長25m、克0、6m、高(gao)為(wei)2d3(d為(wei)波(bo)紋管(guan)直徑)，B型腳(jiao)手架(jia)一(yi)(yi)般克為(wei)25m高(gao)依據波(bo)紋管(guan)直徑大小拼裝(zhuang)接(jie)縫位(wei)置確定(ding)尺(chi)寸。腳(jiao)手架(jia)按上述尺(chi)寸搭(da)設(she)便于施工、

2、拼裝類型與搭接方(fang)式：拼裝以中(zhong)心(xin)軸線為(wei)基準，由(you)中(zhong)心(xin)向兩端對稱進行安裝，直(zhi)至兩端。1斷面(mian)(奇數斷面(mian))、Ⅱ斷面(mian)(偶數斷面(mian))、加(jia)強斷面(mian)(偶數斷管(guan)管(guan)片）

3、波紋管(guan)拼裝(zhuang)：采(cai)用刻(ke)(ke)槽(cao)法施工的地基(ji)(ji)，安(an)(an)裝(zhuang)吊(diao)車依據(ju)刻(ke)(ke)槽(cao)深度，依次安(an)(an)裝(zhuang)底部管(guan)片(pian)(pian)。底部管(guan)片(pian)(pian)安(an)(an)裝(zhuang)完成后對剩余(yu)管(guan)片(pian)(pian)進行安(an)(an)裝(zhuang)。管(guan)片(pian)(pian)安(an)(an)裝(zhuang)同平(ping)基(ji)(ji)上的鋼波紋管(guan)施工。

4、加強斷面拼裝

當波紋(wen)管(guan)(guan)涵(han)直徑較(jiao)大(da)、填土高度較(jiao)高時(shi)，必(bi)須(xu)設(she)置加強(qiang)管(guan)(guan)片(pian)，稱為加強(qiang)圈”，加強(qiang)斷面的管(guan)(guan)片(pian)安裝(zhuang)工序。
