大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝支架(jia)(jia):搭(da)設(she)腳(jiao)手(shou)(shou)架(jia)(jia)根據(ju)波紋(wen)(wen)管(guan)(guan)的直(zhi)徑(jing)提前(qian)確定(ding)，采(cai)用管(guan)(guan)扣連接鋼(gang)管(guan)(guan)的方式搭(da)設(she)腳(jiao)手(shou)(shou)架(jia)(jia)，形式分(fen)A型(xing)和B型(xing)腳(jiao)手(shou)(shou)架(jia)(jia)長(chang)度一般長(chang)25m、克0、6m、高為2d3(d為波紋(wen)(wen)管(guan)(guan)直(zhi)徑(jing))，B型(xing)腳(jiao)手(shou)(shou)架(jia)(jia)一般克為25m高依據(ju)波紋(wen)(wen)管(guan)(guan)直(zhi)徑(jing)大(da)小拼裝接縫位(wei)置確定(ding)尺寸(cun)。腳(jiao)手(shou)(shou)架(jia)(jia)按上述尺寸(cun)搭(da)設(she)便于施工、

2、拼裝類型與搭接方式(shi)：拼裝以中(zhong)心(xin)軸(zhou)線(xian)為基準，由中(zhong)心(xin)向兩(liang)端(duan)對稱進行安(an)裝，直(zhi)至兩(liang)端(duan)。1斷面(mian)(mian)(mian)(mian)(奇(qi)數斷面(mian)(mian)(mian)(mian))、Ⅱ斷面(mian)(mian)(mian)(mian)(偶數斷面(mian)(mian)(mian)(mian))、加強斷面(mian)(mian)(mian)(mian)(偶數斷管管片）

3、波(bo)紋管(guan)拼(pin)裝(zhuang)(zhuang)：采用刻(ke)槽(cao)法(fa)施工的地基，安(an)裝(zhuang)(zhuang)吊車依(yi)據刻(ke)槽(cao)深度，依(yi)次安(an)裝(zhuang)(zhuang)底(di)(di)部管(guan)片(pian)。底(di)(di)部管(guan)片(pian)安(an)裝(zhuang)(zhuang)完成后(hou)對剩(sheng)余管(guan)片(pian)進行(xing)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

當波紋管涵直徑較大、填(tian)土高度較高時，必須設置加(jia)(jia)強管片，稱為加(jia)(jia)強圈”，加(jia)(jia)強斷面的管片安裝(zhuang)工序。
