大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼裝支架(jia):搭(da)設腳(jiao)手架(jia)根據(ju)波紋管(guan)的(de)直徑(jing)提(ti)前確定，采(cai)用管(guan)扣連接鋼管(guan)的(de)方式(shi)搭(da)設腳(jiao)手架(jia)，形(xing)式(shi)分A型(xing)和B型(xing)腳(jiao)手架(jia)長度一般(ban)長25m、克0、6m、高為2d3(d為波紋管(guan)直徑(jing))，B型(xing)腳(jiao)手架(jia)一般(ban)克為25m高依據(ju)波紋管(guan)直徑(jing)大小拼裝接縫(feng)位置確定尺寸(cun)。腳(jiao)手架(jia)按上述尺寸(cun)搭(da)設便于施工(gong)、

2、拼裝類型與(yu)搭接方式：拼裝以(yi)中(zhong)心(xin)軸線為基準，由中(zhong)心(xin)向兩(liang)端對稱(cheng)進行安裝，直至(zhi)兩(liang)端。1斷(duan)面(mian)(奇數(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶(ou)數(shu)斷(duan)面(mian))、加強斷(duan)面(mian)(偶(ou)數(shu)斷(duan)管管片）

3、波(bo)紋管(guan)拼裝(zhuang)(zhuang)(zhuang)：采用刻(ke)槽法施工(gong)的地基，安(an)裝(zhuang)(zhuang)(zhuang)吊車依(yi)據刻(ke)槽深度，依(yi)次安(an)裝(zhuang)(zhuang)(zhuang)底(di)部(bu)管(guan)片(pian)。底(di)部(bu)管(guan)片(pian)安(an)裝(zhuang)(zhuang)(zhuang)完成后(hou)對剩(sheng)余管(guan)片(pian)進(jin)行安(an)裝(zhuang)(zhuang)(zhuang)。管(guan)片(pian)安(an)裝(zhuang)(zhuang)(zhuang)同平基上(shang)的鋼波(bo)紋管(guan)施工(gong)。

4、加強斷面拼裝

當波紋管(guan)涵(han)直徑較大、填土高(gao)度較高(gao)時，必須設置加強(qiang)管(guan)片，稱為加強(qiang)圈”，加強(qiang)斷面的管(guan)片安裝(zhuang)工序。
