大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝支架(jia)(jia):搭(da)設(she)腳手(shou)架(jia)(jia)根據(ju)波(bo)紋管(guan)(guan)的直(zhi)(zhi)徑提(ti)前確定，采用管(guan)(guan)扣連接鋼(gang)管(guan)(guan)的方式搭(da)設(she)腳手(shou)架(jia)(jia)，形(xing)式分A型(xing)和B型(xing)腳手(shou)架(jia)(jia)長度一般(ban)長25m、克0、6m、高為2d3(d為波(bo)紋管(guan)(guan)直(zhi)(zhi)徑)，B型(xing)腳手(shou)架(jia)(jia)一般(ban)克為25m高依(yi)據(ju)波(bo)紋管(guan)(guan)直(zhi)(zhi)徑大小拼裝接縫位置確定尺寸。腳手(shou)架(jia)(jia)按上(shang)述尺寸搭(da)設(she)便于施工(gong)、

2、拼(pin)裝(zhuang)類型(xing)與搭接方(fang)式：拼(pin)裝(zhuang)以中心軸線為基準(zhun)，由中心向兩端對(dui)稱進行安裝(zhuang)，直至兩端。1斷面(奇(qi)數(shu)斷面)、Ⅱ斷面(偶數(shu)斷面)、加強斷面(偶數(shu)斷管管片）

3、波(bo)紋管拼(pin)裝(zhuang)(zhuang)：采用刻槽法(fa)施(shi)工的地(di)基，安裝(zhuang)(zhuang)吊(diao)車依據刻槽深度(du)，依次安裝(zhuang)(zhuang)底部(bu)管片。底部(bu)管片安裝(zhuang)(zhuang)完成后對剩余管片進(jin)行安裝(zhuang)(zhuang)。管片安裝(zhuang)(zhuang)同(tong)平基上的鋼波(bo)紋管施(shi)工。

4、加強斷面拼裝

當波(bo)紋(wen)管涵(han)直(zhi)徑(jing)較(jiao)大、填土(tu)高度較(jiao)高時，必須設置加強管片(pian)，稱為加強圈”，加強斷面(mian)的管片(pian)安裝工序。
