大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼裝(zhuang)支架:搭(da)設腳(jiao)(jiao)手(shou)(shou)架根據(ju)波(bo)(bo)紋(wen)管的直徑(jing)提前確定，采用(yong)管扣(kou)連接鋼管的方(fang)式(shi)搭(da)設腳(jiao)(jiao)手(shou)(shou)架，形(xing)式(shi)分A型(xing)和B型(xing)腳(jiao)(jiao)手(shou)(shou)架長度一般長25m、克0、6m、高(gao)為(wei)2d3(d為(wei)波(bo)(bo)紋(wen)管直徑(jing))，B型(xing)腳(jiao)(jiao)手(shou)(shou)架一般克為(wei)25m高(gao)依據(ju)波(bo)(bo)紋(wen)管直徑(jing)大小拼裝(zhuang)接縫位置(zhi)確定尺寸。腳(jiao)(jiao)手(shou)(shou)架按上述尺寸搭(da)設便于施工、

2、拼(pin)裝類型(xing)與(yu)搭(da)接方式：拼(pin)裝以(yi)中(zhong)心(xin)軸線為(wei)基準，由中(zhong)心(xin)向兩端對稱進行安裝，直至兩端。1斷(duan)面(mian)(奇數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數斷(duan)面(mian))、加強斷(duan)面(mian)(偶數斷(duan)管(guan)管(guan)片(pian)）

3、波(bo)紋(wen)管(guan)拼(pin)裝(zhuang)(zhuang)：采(cai)用刻(ke)槽法(fa)施(shi)工的地基(ji)，安(an)(an)裝(zhuang)(zhuang)吊車依(yi)(yi)據(ju)刻(ke)槽深度，依(yi)(yi)次安(an)(an)裝(zhuang)(zhuang)底部管(guan)片。底部管(guan)片安(an)(an)裝(zhuang)(zhuang)完成后對(dui)剩余管(guan)片進行安(an)(an)裝(zhuang)(zhuang)。管(guan)片安(an)(an)裝(zhuang)(zhuang)同平基(ji)上(shang)的鋼波(bo)紋(wen)管(guan)施(shi)工。

4、加強斷面拼裝

當波紋管涵(han)直徑較大、填土高(gao)度較高(gao)時(shi)，必須設置加強管片，稱為(wei)加強圈”，加強斷面的管片安裝(zhuang)工序。
