大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)(da)設拼裝支架(jia)(jia):搭(da)(da)(da)設腳(jiao)手(shou)架(jia)(jia)根據波紋(wen)管(guan)的(de)直徑(jing)(jing)提前確定(ding)，采用管(guan)扣(kou)連接鋼管(guan)的(de)方(fang)式(shi)(shi)搭(da)(da)(da)設腳(jiao)手(shou)架(jia)(jia)，形式(shi)(shi)分(fen)A型(xing)和B型(xing)腳(jiao)手(shou)架(jia)(jia)長度一般長25m、克(ke)0、6m、高(gao)為(wei)2d3(d為(wei)波紋(wen)管(guan)直徑(jing)(jing))，B型(xing)腳(jiao)手(shou)架(jia)(jia)一般克(ke)為(wei)25m高(gao)依據波紋(wen)管(guan)直徑(jing)(jing)大小(xiao)拼裝接縫位置確定(ding)尺寸(cun)(cun)。腳(jiao)手(shou)架(jia)(jia)按上述尺寸(cun)(cun)搭(da)(da)(da)設便于施工、

2、拼(pin)裝類型與搭接方(fang)式：拼(pin)裝以中心軸線為基準，由(you)中心向兩(liang)端對稱進行安裝，直(zhi)至兩(liang)端。1斷(duan)(duan)(duan)面(奇數斷(duan)(duan)(duan)面)、Ⅱ斷(duan)(duan)(duan)面(偶數斷(duan)(duan)(duan)面)、加強(qiang)斷(duan)(duan)(duan)面(偶數斷(duan)(duan)(duan)管管片）

3、波(bo)紋管拼裝：采用刻槽法施(shi)工(gong)的地(di)基，安(an)(an)裝吊(diao)車依據刻槽深度，依次(ci)安(an)(an)裝底(di)部管片(pian)。底(di)部管片(pian)安(an)(an)裝完成后對剩余管片(pian)進行安(an)(an)裝。管片(pian)安(an)(an)裝同(tong)平基上的鋼波(bo)紋管施(shi)工(gong)。

4、加強斷面拼裝

當波紋管涵(han)直徑較大(da)、填土高(gao)(gao)度較高(gao)(gao)時(shi)，必須設置加強管片(pian)，稱為加強圈”，加強斷面的管片(pian)安裝工序。
