大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝支架(jia):搭設腳(jiao)(jiao)手(shou)(shou)架(jia)根據(ju)波(bo)紋管(guan)的直徑(jing)提(ti)前(qian)確定，采用管(guan)扣連接鋼管(guan)的方式(shi)(shi)搭設腳(jiao)(jiao)手(shou)(shou)架(jia)，形式(shi)(shi)分A型和(he)B型腳(jiao)(jiao)手(shou)(shou)架(jia)長(chang)度一(yi)般長(chang)25m、克(ke)0、6m、高為(wei)2d3(d為(wei)波(bo)紋管(guan)直徑(jing))，B型腳(jiao)(jiao)手(shou)(shou)架(jia)一(yi)般克(ke)為(wei)25m高依(yi)據(ju)波(bo)紋管(guan)直徑(jing)大小拼(pin)裝接縫位置確定尺寸。腳(jiao)(jiao)手(shou)(shou)架(jia)按上(shang)述(shu)尺寸搭設便于(yu)施工(gong)、

2、拼(pin)裝(zhuang)類型(xing)與搭接方式(shi)：拼(pin)裝(zhuang)以中心軸線為基(ji)準，由中心向(xiang)兩端對稱進(jin)行安裝(zhuang)，直(zhi)至兩端。1斷(duan)(duan)(duan)面(mian)(奇數斷(duan)(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)(duan)面(mian)(偶數斷(duan)(duan)(duan)面(mian))、加強斷(duan)(duan)(duan)面(mian)(偶數斷(duan)(duan)(duan)管管片）

3、波紋管(guan)拼裝：采用刻(ke)(ke)槽法施(shi)工(gong)的(de)地基，安(an)裝吊車依(yi)據(ju)刻(ke)(ke)槽深度(du)，依(yi)次安(an)裝底(di)部(bu)管(guan)片(pian)。底(di)部(bu)管(guan)片(pian)安(an)裝完成后(hou)對剩余管(guan)片(pian)進行安(an)裝。管(guan)片(pian)安(an)裝同平基上的(de)鋼(gang)波紋管(guan)施(shi)工(gong)。
