大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼裝支架(jia):搭(da)設腳手(shou)架(jia)根據(ju)波(bo)紋(wen)管(guan)(guan)的直徑(jing)(jing)提前(qian)確定(ding)，采用(yong)管(guan)(guan)扣連(lian)接(jie)鋼管(guan)(guan)的方式搭(da)設腳手(shou)架(jia)，形式分(fen)A型和(he)B型腳手(shou)架(jia)長(chang)度一般長(chang)25m、克0、6m、高為(wei)2d3(d為(wei)波(bo)紋(wen)管(guan)(guan)直徑(jing)(jing))，B型腳手(shou)架(jia)一般克為(wei)25m高依據(ju)波(bo)紋(wen)管(guan)(guan)直徑(jing)(jing)大小(xiao)拼裝接(jie)縫位置確定(ding)尺寸(cun)。腳手(shou)架(jia)按上述尺寸(cun)搭(da)設便于施(shi)工、

2、拼裝類型與(yu)搭接方式(shi)：拼裝以(yi)中心(xin)軸(zhou)線為(wei)基準，由中心(xin)向兩端(duan)對稱(cheng)進行安裝，直至兩端(duan)。1斷(duan)面(mian)(mian)(mian)(奇(qi)數斷(duan)面(mian)(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(mian)(偶數斷(duan)面(mian)(mian)(mian))、加強斷(duan)面(mian)(mian)(mian)(偶數斷(duan)管管片）

3、波(bo)(bo)紋(wen)管(guan)拼裝：采用刻槽(cao)法施(shi)工的地基，安(an)(an)裝吊車(che)依(yi)據(ju)刻槽(cao)深度(du)，依(yi)次安(an)(an)裝底部(bu)管(guan)片(pian)(pian)(pian)。底部(bu)管(guan)片(pian)(pian)(pian)安(an)(an)裝完成(cheng)后(hou)對(dui)剩余(yu)管(guan)片(pian)(pian)(pian)進行(xing)安(an)(an)裝。管(guan)片(pian)(pian)(pian)安(an)(an)裝同(tong)平基上的鋼波(bo)(bo)紋(wen)管(guan)施(shi)工。

4、加強斷面拼裝

當波紋管(guan)涵直徑較(jiao)大、填(tian)土(tu)高度較(jiao)高時，必須設置加強管(guan)片(pian)，稱(cheng)為加強圈(quan)”，加強斷(duan)面(mian)的管(guan)片(pian)安裝工序。
