大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)(pin)裝支架(jia)(jia):搭設腳(jiao)手架(jia)(jia)根(gen)據波紋管(guan)(guan)的(de)直徑提前確(que)定，采用管(guan)(guan)扣連接鋼管(guan)(guan)的(de)方式搭設腳(jiao)手架(jia)(jia)，形(xing)式分A型和B型腳(jiao)手架(jia)(jia)長度一般(ban)長25m、克0、6m、高(gao)(gao)為(wei)2d3(d為(wei)波紋管(guan)(guan)直徑)，B型腳(jiao)手架(jia)(jia)一般(ban)克為(wei)25m高(gao)(gao)依據波紋管(guan)(guan)直徑大(da)小(xiao)拼(pin)(pin)裝接縫位置確(que)定尺寸。腳(jiao)手架(jia)(jia)按上述尺寸搭設便于施工、

2、拼裝(zhuang)(zhuang)類(lei)型(xing)與搭接方式(shi)：拼裝(zhuang)(zhuang)以中(zhong)心軸(zhou)線為基準，由中(zhong)心向兩端對稱(cheng)進行(xing)安裝(zhuang)(zhuang)，直至兩端。1斷面(mian)(奇數(shu)斷面(mian))、Ⅱ斷面(mian)(偶數(shu)斷面(mian))、加強斷面(mian)(偶數(shu)斷管管片）

3、波(bo)紋管(guan)(guan)拼裝(zhuang)(zhuang)：采(cai)用刻槽法施工(gong)的地(di)基(ji)，安(an)裝(zhuang)(zhuang)吊車依(yi)據(ju)刻槽深度，依(yi)次(ci)安(an)裝(zhuang)(zhuang)底(di)部管(guan)(guan)片。底(di)部管(guan)(guan)片安(an)裝(zhuang)(zhuang)完成(cheng)后對剩(sheng)余管(guan)(guan)片進行安(an)裝(zhuang)(zhuang)。管(guan)(guan)片安(an)裝(zhuang)(zhuang)同平(ping)基(ji)上的鋼波(bo)紋管(guan)(guan)施工(gong)。

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，必須設置加強管(guan)片，稱為加強圈”，加強斷(duan)面的(de)管(guan)片安裝(zhuang)工序。
