大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝支(zhi)架(jia):搭(da)設(she)腳(jiao)手(shou)架(jia)根據波紋管(guan)(guan)的直徑提前確定(ding)，采用管(guan)(guan)扣連接(jie)鋼管(guan)(guan)的方式搭(da)設(she)腳(jiao)手(shou)架(jia)，形式分A型和B型腳(jiao)手(shou)架(jia)長(chang)(chang)度(du)一般長(chang)(chang)25m、克0、6m、高為2d3(d為波紋管(guan)(guan)直徑)，B型腳(jiao)手(shou)架(jia)一般克為25m高依(yi)據波紋管(guan)(guan)直徑大小拼裝接(jie)縫位置確定(ding)尺寸。腳(jiao)手(shou)架(jia)按上述尺寸搭(da)設(she)便于施工、

2、拼(pin)裝(zhuang)類型與搭接方式：拼(pin)裝(zhuang)以中心軸(zhou)線為基準，由中心向兩端對稱進行安裝(zhuang)，直(zhi)至兩端。1斷面(mian)(奇(qi)數(shu)(shu)斷面(mian))、Ⅱ斷面(mian)(偶(ou)數(shu)(shu)斷面(mian))、加(jia)強斷面(mian)(偶(ou)數(shu)(shu)斷管(guan)管(guan)片）

3、波紋管(guan)(guan)拼裝(zhuang)(zhuang)：采用刻槽(cao)法(fa)施工(gong)的(de)(de)地基(ji)，安(an)(an)裝(zhuang)(zhuang)吊車依據刻槽(cao)深度，依次安(an)(an)裝(zhuang)(zhuang)底(di)部管(guan)(guan)片(pian)(pian)。底(di)部管(guan)(guan)片(pian)(pian)安(an)(an)裝(zhuang)(zhuang)完成(cheng)后對剩余(yu)管(guan)(guan)片(pian)(pian)進行安(an)(an)裝(zhuang)(zhuang)。管(guan)(guan)片(pian)(pian)安(an)(an)裝(zhuang)(zhuang)同平基(ji)上的(de)(de)鋼波紋管(guan)(guan)施工(gong)。

4、加強斷面拼裝

當(dang)波紋管涵直徑較(jiao)大、填土高(gao)(gao)度較(jiao)高(gao)(gao)時，必須設置加強(qiang)管片，稱為加強(qiang)圈”，加強(qiang)斷面(mian)的管片安裝工序。
