大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝(zhuang)支架(jia)(jia):搭設腳(jiao)手(shou)架(jia)(jia)根據波紋(wen)管(guan)的直(zhi)徑(jing)提前確(que)定，采(cai)用管(guan)扣連接(jie)鋼管(guan)的方式搭設腳(jiao)手(shou)架(jia)(jia)，形(xing)式分A型(xing)(xing)和B型(xing)(xing)腳(jiao)手(shou)架(jia)(jia)長(chang)度一般(ban)長(chang)25m、克0、6m、高為2d3(d為波紋(wen)管(guan)直(zhi)徑(jing))，B型(xing)(xing)腳(jiao)手(shou)架(jia)(jia)一般(ban)克為25m高依據波紋(wen)管(guan)直(zhi)徑(jing)大(da)小拼裝(zhuang)接(jie)縫位置確(que)定尺寸。腳(jiao)手(shou)架(jia)(jia)按上(shang)述尺寸搭設便于施工、

2、拼裝類型與搭接(jie)方式：拼裝以中(zhong)心軸線為基準，由中(zhong)心向兩端對稱進行安裝，直至兩端。1斷(duan)面(mian)(奇(qi)數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶(ou)數斷(duan)面(mian))、加(jia)強斷(duan)面(mian)(偶(ou)數斷(duan)管管片）

3、波紋(wen)管(guan)(guan)拼(pin)裝：采用刻槽(cao)法施(shi)工(gong)的(de)地基(ji)，安(an)裝吊車(che)依據刻槽(cao)深度，依次安(an)裝底(di)部(bu)管(guan)(guan)片。底(di)部(bu)管(guan)(guan)片安(an)裝完(wan)成后對剩余(yu)管(guan)(guan)片進(jin)行(xing)安(an)裝。管(guan)(guan)片安(an)裝同平基(ji)上的(de)鋼波紋(wen)管(guan)(guan)施(shi)工(gong)。

4、加強斷面拼裝

當波紋(wen)管涵直徑(jing)較大、填土高度較高時(shi)，必須設置(zhi)加強(qiang)管片，稱(cheng)為加強(qiang)圈”，加強(qiang)斷面(mian)的管片安(an)裝工序。
