大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼(pin)裝支架(jia)(jia):搭(da)設腳手架(jia)(jia)根(gen)據波(bo)紋管的(de)直(zhi)徑提(ti)前(qian)確定，采用管扣連(lian)接鋼(gang)管的(de)方(fang)式搭(da)設腳手架(jia)(jia)，形(xing)式分A型和(he)B型腳手架(jia)(jia)長度一般長25m、克0、6m、高為2d3(d為波(bo)紋管直(zhi)徑)，B型腳手架(jia)(jia)一般克為25m高依(yi)據波(bo)紋管直(zhi)徑大小拼(pin)裝接縫位置確定尺寸。腳手架(jia)(jia)按(an)上述尺寸搭(da)設便于(yu)施工(gong)、

2、拼裝類型與搭接方式：拼裝以中(zhong)心(xin)軸線(xian)為基(ji)準，由中(zhong)心(xin)向兩(liang)端對稱(cheng)進行安裝，直至兩(liang)端。1斷面(奇數(shu)斷面)、Ⅱ斷面(偶數(shu)斷面)、加強(qiang)斷面(偶數(shu)斷管管片(pian)）

3、波(bo)(bo)紋管(guan)拼裝(zhuang)：采(cai)用刻(ke)槽(cao)法施工的地基(ji)，安(an)裝(zhuang)吊車依據刻(ke)槽(cao)深度(du)，依次安(an)裝(zhuang)底部管(guan)片(pian)。底部管(guan)片(pian)安(an)裝(zhuang)完成后對(dui)剩(sheng)余管(guan)片(pian)進行安(an)裝(zhuang)。管(guan)片(pian)安(an)裝(zhuang)同平基(ji)上的鋼波(bo)(bo)紋管(guan)施工。

4、加強斷面拼裝

當波(bo)紋管(guan)涵直徑較(jiao)大、填土高度較(jiao)高時，必須(xu)設置加強(qiang)管(guan)片(pian)，稱為加強(qiang)圈”，加強(qiang)斷(duan)面(mian)的(de)管(guan)片(pian)安裝工序。
