大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝支架(jia)(jia):搭設(she)腳(jiao)手架(jia)(jia)根據波紋(wen)管(guan)(guan)的直(zhi)徑提前確定，采用管(guan)(guan)扣連接鋼管(guan)(guan)的方式(shi)(shi)搭設(she)腳(jiao)手架(jia)(jia)，形式(shi)(shi)分A型(xing)和B型(xing)腳(jiao)手架(jia)(jia)長(chang)(chang)度一(yi)般長(chang)(chang)25m、克0、6m、高為2d3(d為波紋(wen)管(guan)(guan)直(zhi)徑)，B型(xing)腳(jiao)手架(jia)(jia)一(yi)般克為25m高依(yi)據波紋(wen)管(guan)(guan)直(zhi)徑大小拼裝接縫位(wei)置確定尺(chi)寸(cun)。腳(jiao)手架(jia)(jia)按上述(shu)尺(chi)寸(cun)搭設(she)便于施工、

2、拼裝(zhuang)類型與搭接(jie)方(fang)式：拼裝(zhuang)以中心軸線為基準(zhun)，由中心向兩(liang)端(duan)(duan)對稱進(jin)行(xing)安裝(zhuang)，直至兩(liang)端(duan)(duan)。1斷(duan)(duan)(duan)面(奇(qi)數斷(duan)(duan)(duan)面)、Ⅱ斷(duan)(duan)(duan)面(偶數斷(duan)(duan)(duan)面)、加強斷(duan)(duan)(duan)面(偶數斷(duan)(duan)(duan)管管片）

3、波(bo)紋(wen)管拼裝(zhuang)(zhuang)：采用刻槽法施工的地基(ji)，安(an)裝(zhuang)(zhuang)吊車依據刻槽深度，依次安(an)裝(zhuang)(zhuang)底部管片。底部管片安(an)裝(zhuang)(zhuang)完成后對剩(sheng)余管片進(jin)行安(an)裝(zhuang)(zhuang)。管片安(an)裝(zhuang)(zhuang)同平(ping)基(ji)上的鋼波(bo)紋(wen)管施工。

4、加強斷面拼裝

當波紋(wen)管涵直徑較大、填土高(gao)度較高(gao)時，必(bi)須設(she)置加(jia)強(qiang)管片(pian)，稱(cheng)為(wei)加(jia)強(qiang)圈”，加(jia)強(qiang)斷面的管片(pian)安裝工序。
