大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼(pin)裝(zhuang)支架:搭(da)設(she)腳手(shou)(shou)(shou)(shou)架根據(ju)波紋管(guan)(guan)的直徑提前確定，采用管(guan)(guan)扣連接鋼管(guan)(guan)的方式(shi)搭(da)設(she)腳手(shou)(shou)(shou)(shou)架，形(xing)式(shi)分A型和B型腳手(shou)(shou)(shou)(shou)架長度一般長25m、克0、6m、高(gao)為2d3(d為波紋管(guan)(guan)直徑)，B型腳手(shou)(shou)(shou)(shou)架一般克為25m高(gao)依據(ju)波紋管(guan)(guan)直徑大(da)小拼(pin)裝(zhuang)接縫位(wei)置確定尺(chi)寸。腳手(shou)(shou)(shou)(shou)架按(an)上述尺(chi)寸搭(da)設(she)便(bian)于施工、

2、拼裝(zhuang)類型與搭接方式：拼裝(zhuang)以中(zhong)心軸(zhou)線(xian)為(wei)基(ji)準，由中(zhong)心向(xiang)兩端對稱進(jin)行安裝(zhuang)，直至兩端。1斷面(奇數斷面)、Ⅱ斷面(偶(ou)數斷面)、加強斷面(偶(ou)數斷管管片）

3、波紋管拼裝：采用刻槽法施(shi)工(gong)的(de)地基，安(an)裝吊車(che)依(yi)據刻槽深度，依(yi)次(ci)安(an)裝底部(bu)管片(pian)。底部(bu)管片(pian)安(an)裝完成后對(dui)剩余管片(pian)進行安(an)裝。管片(pian)安(an)裝同平(ping)基上的(de)鋼波紋管施(shi)工(gong)。

4、加強斷面拼裝

當(dang)波(bo)紋管涵直(zhi)徑較大、填(tian)土高度(du)較高時，必須設置加強管片(pian)，稱為加強圈”，加強斷面的管片(pian)安裝工序(xu)。
