大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼(pin)裝支(zhi)架(jia)(jia):搭(da)設(she)腳(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)根據(ju)波(bo)(bo)紋(wen)管的(de)直徑提前確定，采(cai)用管扣連(lian)接鋼管的(de)方式(shi)搭(da)設(she)腳(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)，形式(shi)分(fen)A型(xing)和(he)B型(xing)腳(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)長(chang)度一(yi)般(ban)長(chang)25m、克(ke)0、6m、高(gao)為2d3(d為波(bo)(bo)紋(wen)管直徑)，B型(xing)腳(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)一(yi)般(ban)克(ke)為25m高(gao)依(yi)據(ju)波(bo)(bo)紋(wen)管直徑大小拼(pin)裝接縫位置確定尺寸。腳(jiao)(jiao)(jiao)手(shou)(shou)架(jia)(jia)按上述尺寸搭(da)設(she)便于施(shi)工(gong)、

2、拼(pin)裝類(lei)型(xing)與(yu)搭接方式(shi)：拼(pin)裝以中心軸線為基準(zhun)，由(you)中心向(xiang)兩端對稱進行安(an)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(ou)數斷(duan)面(mian)(mian))、加強斷(duan)面(mian)(mian)(偶(ou)數斷(duan)管管片）

3、波紋管(guan)拼裝：采用(yong)刻槽(cao)法(fa)施工的地基(ji)，安(an)裝吊車(che)依據(ju)刻槽(cao)深度，依次安(an)裝底(di)部管(guan)片。底(di)部管(guan)片安(an)裝完成后對剩余管(guan)片進行安(an)裝。管(guan)片安(an)裝同平基(ji)上的鋼波紋管(guan)施工。

4、加強斷面拼裝

當(dang)波紋管涵直(zhi)徑較(jiao)大、填土(tu)高(gao)度較(jiao)高(gao)時(shi)，必須設(she)置加強管片(pian)，稱為(wei)加強圈”，加強斷面的管片(pian)安裝(zhuang)工序。
