大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝支架(jia)(jia):搭設(she)腳(jiao)(jiao)手(shou)架(jia)(jia)根據波(bo)紋管的直(zhi)徑提(ti)前(qian)確定，采用管扣連接鋼管的方(fang)式搭設(she)腳(jiao)(jiao)手(shou)架(jia)(jia)，形式分A型和B型腳(jiao)(jiao)手(shou)架(jia)(jia)長度一(yi)般長25m、克0、6m、高為2d3(d為波(bo)紋管直(zhi)徑)，B型腳(jiao)(jiao)手(shou)架(jia)(jia)一(yi)般克為25m高依據波(bo)紋管直(zhi)徑大小拼裝接縫(feng)位置確定尺寸(cun)(cun)。腳(jiao)(jiao)手(shou)架(jia)(jia)按上(shang)述(shu)尺寸(cun)(cun)搭設(she)便于施工(gong)、

2、拼裝(zhuang)(zhuang)(zhuang)類型與搭接(jie)方式：拼裝(zhuang)(zhuang)(zhuang)以中心軸線為基準(zhun)，由中心向兩端對稱進(jin)行安裝(zhuang)(zhuang)(zhuang)，直(zhi)至兩端。1斷面(奇數斷面)、Ⅱ斷面(偶(ou)(ou)數斷面)、加強斷面(偶(ou)(ou)數斷管管片）

3、波紋(wen)管(guan)拼裝(zhuang)(zhuang)：采用刻槽(cao)法施(shi)工的地基，安(an)裝(zhuang)(zhuang)吊(diao)車依據刻槽(cao)深度，依次安(an)裝(zhuang)(zhuang)底部管(guan)片。底部管(guan)片安(an)裝(zhuang)(zhuang)完(wan)成(cheng)后對剩余管(guan)片進行安(an)裝(zhuang)(zhuang)。管(guan)片安(an)裝(zhuang)(zhuang)同平基上的鋼(gang)波紋(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(tu)高度較高時，必須(xu)設置加(jia)強(qiang)(qiang)管片(pian)，稱為加(jia)強(qiang)(qiang)圈”，加(jia)強(qiang)(qiang)斷面的(de)管片(pian)安裝工(gong)序(xu)。
