大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)(she)(she)拼裝(zhuang)(zhuang)支架(jia):搭(da)(da)設(she)(she)(she)腳(jiao)(jiao)手(shou)架(jia)根據波紋(wen)(wen)管(guan)(guan)的(de)直徑(jing)提前(qian)確(que)定，采用(yong)管(guan)(guan)扣連(lian)接鋼管(guan)(guan)的(de)方(fang)式搭(da)(da)設(she)(she)(she)腳(jiao)(jiao)手(shou)架(jia)，形式分A型和B型腳(jiao)(jiao)手(shou)架(jia)長(chang)度(du)一般長(chang)25m、克0、6m、高為2d3(d為波紋(wen)(wen)管(guan)(guan)直徑(jing))，B型腳(jiao)(jiao)手(shou)架(jia)一般克為25m高依據波紋(wen)(wen)管(guan)(guan)直徑(jing)大小拼裝(zhuang)(zhuang)接縫位置確(que)定尺(chi)寸(cun)。腳(jiao)(jiao)手(shou)架(jia)按上述(shu)尺(chi)寸(cun)搭(da)(da)設(she)(she)(she)便于(yu)施工(gong)、

2、拼裝(zhuang)類型與搭(da)接方式：拼裝(zhuang)以(yi)中心軸線為基準，由中心向兩端對稱進行安裝(zhuang)，直至兩端。1斷(duan)面(奇數(shu)(shu)斷(duan)面)、Ⅱ斷(duan)面(偶數(shu)(shu)斷(duan)面)、加強斷(duan)面(偶數(shu)(shu)斷(duan)管管片(pian)）

3、波紋管(guan)(guan)拼裝(zhuang)：采用(yong)刻(ke)(ke)槽法施(shi)(shi)工的地基，安(an)(an)裝(zhuang)吊(diao)車依據刻(ke)(ke)槽深度，依次安(an)(an)裝(zhuang)底部管(guan)(guan)片。底部管(guan)(guan)片安(an)(an)裝(zhuang)完成(cheng)后對剩余管(guan)(guan)片進行安(an)(an)裝(zhuang)。管(guan)(guan)片安(an)(an)裝(zhuang)同平(ping)基上的鋼(gang)波紋管(guan)(guan)施(shi)(shi)工。

4、加強斷面拼裝

當波紋管涵直(zhi)徑較(jiao)大(da)、填土高度較(jiao)高時，必須(xu)設(she)置(zhi)加(jia)強(qiang)(qiang)管片，稱為加(jia)強(qiang)(qiang)圈”，加(jia)強(qiang)(qiang)斷面的管片安裝工序。
