大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝(zhuang)支(zhi)架(jia):搭設腳手(shou)架(jia)根據波紋管的(de)(de)直(zhi)徑(jing)(jing)提前確定，采用(yong)管扣連接鋼管的(de)(de)方式搭設腳手(shou)架(jia)，形式分A型和B型腳手(shou)架(jia)長度(du)一般長25m、克0、6m、高為(wei)2d3(d為(wei)波紋管直(zhi)徑(jing)(jing))，B型腳手(shou)架(jia)一般克為(wei)25m高依(yi)據波紋管直(zhi)徑(jing)(jing)大小拼裝(zhuang)接縫(feng)位置確定尺寸(cun)。腳手(shou)架(jia)按(an)上(shang)述尺寸(cun)搭設便于施工、

2、拼(pin)裝類型與搭接方式：拼(pin)裝以(yi)中(zhong)心軸(zhou)線為基準，由中(zhong)心向兩端(duan)對稱進行安裝，直至兩端(duan)。1斷面(奇數斷面)、Ⅱ斷面(偶(ou)數斷面)、加強(qiang)斷面(偶(ou)數斷管管片）

3、波紋(wen)管(guan)(guan)拼裝(zhuang)：采(cai)用刻(ke)槽(cao)法(fa)施工的地基，安裝(zhuang)吊車依據刻(ke)槽(cao)深度，依次安裝(zhuang)底(di)部(bu)管(guan)(guan)片(pian)。底(di)部(bu)管(guan)(guan)片(pian)安裝(zhuang)完成后對剩(sheng)余管(guan)(guan)片(pian)進行安裝(zhuang)。管(guan)(guan)片(pian)安裝(zhuang)同平基上的鋼波紋(wen)管(guan)(guan)施工。

4、加強斷面拼裝

當波紋管(guan)涵直徑較大、填(tian)土高度較高時，必(bi)須設置加強管(guan)片，稱為加強圈”，加強斷面的管(guan)片安裝工序。
