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)手架(jia)根據波紋管的直徑提前確定(ding)，采用管扣連接(jie)(jie)鋼(gang)管的方式搭設腳(jiao)(jiao)手架(jia)，形式分A型(xing)和B型(xing)腳(jiao)(jiao)手架(jia)長度一般長25m、克0、6m、高為(wei)2d3(d為(wei)波紋管直徑)，B型(xing)腳(jiao)(jiao)手架(jia)一般克為(wei)25m高依據波紋管直徑大小拼(pin)裝接(jie)(jie)縫位置確定(ding)尺寸(cun)。腳(jiao)(jiao)手架(jia)按上述尺寸(cun)搭設便(bian)于施(shi)工、

2、拼(pin)裝類型與搭接方(fang)式：拼(pin)裝以中心軸線為基準，由中心向(xiang)兩端對稱進行安(an)裝，直至兩端。1斷(duan)面(mian)(奇(qi)數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數斷(duan)面(mian))、加強斷(duan)面(mian)(偶數斷(duan)管(guan)管(guan)片）

3、波紋(wen)管(guan)拼裝(zhuang)(zhuang)：采(cai)用刻(ke)槽法施(shi)工的地(di)基，安裝(zhuang)(zhuang)吊車依(yi)據刻(ke)槽深(shen)度，依(yi)次(ci)安裝(zhuang)(zhuang)底部管(guan)片(pian)。底部管(guan)片(pian)安裝(zhuang)(zhuang)完成后對(dui)剩余管(guan)片(pian)進行安裝(zhuang)(zhuang)。管(guan)片(pian)安裝(zhuang)(zhuang)同平基上的鋼波紋(wen)管(guan)施(shi)工。

4、加強斷面拼裝

當波紋(wen)管(guan)(guan)涵直(zhi)徑較(jiao)(jiao)大、填土(tu)高度較(jiao)(jiao)高時，必(bi)須設置(zhi)加強(qiang)(qiang)管(guan)(guan)片，稱為加強(qiang)(qiang)圈”，加強(qiang)(qiang)斷面的管(guan)(guan)片安裝工序(xu)。
