大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼裝支架(jia):搭(da)(da)設腳(jiao)手架(jia)根(gen)據波(bo)紋(wen)管(guan)(guan)的直徑(jing)提前確(que)定，采用(yong)管(guan)(guan)扣連接鋼管(guan)(guan)的方式搭(da)(da)設腳(jiao)手架(jia)，形式分A型和B型腳(jiao)手架(jia)長度(du)一般長25m、克0、6m、高(gao)為(wei)(wei)2d3(d為(wei)(wei)波(bo)紋(wen)管(guan)(guan)直徑(jing))，B型腳(jiao)手架(jia)一般克為(wei)(wei)25m高(gao)依據波(bo)紋(wen)管(guan)(guan)直徑(jing)大小(xiao)拼裝接縫位(wei)置確(que)定尺(chi)寸。腳(jiao)手架(jia)按上述尺(chi)寸搭(da)(da)設便于施工、

2、拼裝(zhuang)類型與搭接方式：拼裝(zhuang)以中(zhong)心(xin)軸線(xian)為基準，由中(zhong)心(xin)向兩端(duan)對稱進行安(an)裝(zhuang)，直至兩端(duan)。1斷(duan)(duan)面(奇(qi)數斷(duan)(duan)面)、Ⅱ斷(duan)(duan)面(偶數斷(duan)(duan)面)、加強斷(duan)(duan)面(偶數斷(duan)(duan)管管片）

3、波紋管拼(pin)裝(zhuang)(zhuang)：采用刻槽法施工的地基，安(an)裝(zhuang)(zhuang)吊車依據刻槽深(shen)度，依次安(an)裝(zhuang)(zhuang)底部管片(pian)(pian)。底部管片(pian)(pian)安(an)裝(zhuang)(zhuang)完成后對剩余管片(pian)(pian)進行(xing)安(an)裝(zhuang)(zhuang)。管片(pian)(pian)安(an)裝(zhuang)(zhuang)同平基上(shang)的鋼波紋管施工。

4、加強斷面拼裝

當波紋管(guan)涵(han)直徑較(jiao)大、填土(tu)高度(du)較(jiao)高時(shi)，必須設置加強(qiang)管(guan)片，稱為(wei)加強(qiang)圈”，加強(qiang)斷面的管(guan)片安裝(zhuang)工序。
