大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼(pin)裝支架(jia)(jia):搭(da)設(she)腳(jiao)手(shou)架(jia)(jia)根據(ju)波(bo)紋管(guan)(guan)的(de)直(zhi)徑提(ti)前確定，采用管(guan)(guan)扣(kou)連接鋼(gang)管(guan)(guan)的(de)方式(shi)搭(da)設(she)腳(jiao)手(shou)架(jia)(jia)，形式(shi)分A型和B型腳(jiao)手(shou)架(jia)(jia)長度一(yi)般長25m、克0、6m、高為2d3(d為波(bo)紋管(guan)(guan)直(zhi)徑)，B型腳(jiao)手(shou)架(jia)(jia)一(yi)般克為25m高依(yi)據(ju)波(bo)紋管(guan)(guan)直(zhi)徑大小拼(pin)裝接縫位置確定尺寸。腳(jiao)手(shou)架(jia)(jia)按上述尺寸搭(da)設(she)便于施工、

2、拼(pin)裝(zhuang)類(lei)型與搭接方式：拼(pin)裝(zhuang)以中(zhong)心(xin)軸線(xian)為基準，由中(zhong)心(xin)向兩(liang)端(duan)(duan)對(dui)稱進(jin)行安(an)裝(zhuang)，直(zhi)至兩(liang)端(duan)(duan)。1斷面(mian)(奇數斷面(mian))、Ⅱ斷面(mian)(偶數斷面(mian))、加強斷面(mian)(偶數斷管管片）

3、波紋(wen)管(guan)拼裝(zhuang)(zhuang)：采用刻槽法施工(gong)的(de)地基(ji)，安(an)裝(zhuang)(zhuang)吊車依據(ju)刻槽深度，依次安(an)裝(zhuang)(zhuang)底(di)部管(guan)片。底(di)部管(guan)片安(an)裝(zhuang)(zhuang)完成后對剩(sheng)余管(guan)片進行安(an)裝(zhuang)(zhuang)。管(guan)片安(an)裝(zhuang)(zhuang)同(tong)平基(ji)上的(de)鋼波紋(wen)管(guan)施工(gong)。

4、加強斷面拼裝

當波紋(wen)管(guan)涵直徑較(jiao)大、填土高度(du)較(jiao)高時，必須設置(zhi)加強管(guan)片，稱為加強圈”，加強斷面(mian)的(de)管(guan)片安裝工序。
