大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼裝(zhuang)支架(jia):搭(da)(da)設腳(jiao)手(shou)架(jia)根據(ju)波(bo)紋管(guan)的直徑提前確定(ding)，采(cai)用(yong)管(guan)扣連接鋼管(guan)的方式(shi)搭(da)(da)設腳(jiao)手(shou)架(jia)，形式(shi)分A型和B型腳(jiao)手(shou)架(jia)長(chang)(chang)度一般長(chang)(chang)25m、克0、6m、高為2d3(d為波(bo)紋管(guan)直徑)，B型腳(jiao)手(shou)架(jia)一般克為25m高依據(ju)波(bo)紋管(guan)直徑大小拼裝(zhuang)接縫位置確定(ding)尺(chi)寸。腳(jiao)手(shou)架(jia)按上述尺(chi)寸搭(da)(da)設便于施工、

2、拼裝(zhuang)(zhuang)類型與搭接方式：拼裝(zhuang)(zhuang)以(yi)中(zhong)心(xin)軸(zhou)線為基(ji)準，由中(zhong)心(xin)向兩(liang)端對稱進行安裝(zhuang)(zhuang)，直至兩(liang)端。1斷(duan)面(奇(qi)數(shu)斷(duan)面)、Ⅱ斷(duan)面(偶數(shu)斷(duan)面)、加強斷(duan)面(偶數(shu)斷(duan)管管片(pian)）

3、波紋(wen)管(guan)拼裝：采用(yong)刻(ke)槽法(fa)施工的地基(ji)，安(an)裝吊車依據刻(ke)槽深度(du)，依次安(an)裝底部管(guan)片(pian)。底部管(guan)片(pian)安(an)裝完成后對剩(sheng)余管(guan)片(pian)進(jin)行安(an)裝。管(guan)片(pian)安(an)裝同平基(ji)上的鋼波紋(wen)管(guan)施工。

首(shou)圈(quan)(quan)波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圈(quan)(quan)為(wei)奇(qi)數斷(duan)面(mian)(mian)，拼(pin)裝時應將(jiang)(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)立于地上(shang)安裝，使(shi)用(yong)(yong)(yong)(yong)鐵鉤的(de)(de)一端(duan)(duan)勾住I斷(duan)面(mian)(mian)片(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)(luo)(luo)絲(si)囗(wei)，用(yong)(yong)(yong)(yong)12噸的(de)(de)吊車勾住鐵鉤的(de)(de)另一端(duan)(duan)，將(jiang)(jiang)(jiang)波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)立于墊(dian)層上(shang)，然(ran)后使(shi)用(yong)(yong)(yong)(yong)同樣的(de)(de)辦法將(jiang)(jiang)(jiang)第二片(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)按圖(tu)(tu)3、21斷(duan)面(mian)(mian)所示的(de)(de)搭接(jie)方式放置(zhi)，使(shi)用(yong)(yong)(yong)(yong)撬棍將(jiang)(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)的(de)(de)螺(luo)(luo)(luo)(luo)栓(shuan)口對齊，將(jiang)(jiang)(jiang)提前準備好(hao)的(de)(de)螺(luo)(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)(luo)紋(wen)(wen)部涂上(shang)渢滑(hua)劑(ji)，由內冋(jiong)外插入孔位；波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)外側套上(shang)凹墊(dian)圈(quan)(quan)或凸(tu)墊(dian)圈(quan)(quan)，遇波(bo)(bo)使(shi)用(yong)(yong)(yong)(yong)凸(tu)墊(dian)圈(quan)(quan)，遇波(bo)(bo)峰(feng)使(shi)用(yong)(yong)(yong)(yong)凹墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外側旋上(shang)螺(luo)(luo)(luo)(luo)母，在用(yong)(yong)(yong)(yong)套筒(tong)扳手預(yu)緊螺(luo)(luo)(luo)(luo)母，然(ran)后使(shi)用(yong)(yong)(yong)(yong)電動扳手緊固螺(luo)(luo)(luo)(luo)母兩塊板(ban)片(pian)(pian)洤全部安裝完畢;波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)的(de)(de)螺(luo)(luo)(luo)(luo)栓(shuan)安裝完畢后，需采(cai)用(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)注膠槍于端(duan)(duan)部接(jie)合處(chu)、緊回件連接(jie)的(de)(de)螺(luo)(luo)(luo)(luo)栓(shuan)孔空(kong)隙處(chu)涂抹中性硅酮(tong)耐候(hou)膠。緊接(jie)著按2#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)的(de)(de)施工拼(pin)裝順序，拼(pin)裝好(hao)首(shou)圈(quan)(quan)波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圖(tu)(tu)36偶數、奇(qi)數斷(duan)面(mian)(mian)交替拼(pin)裝順序

4、加強斷面拼裝

當波(bo)紋管(guan)涵直徑(jing)較大、填(tian)土高度較高時(shi)，必須設(she)置加(jia)強(qiang)管(guan)片，稱(cheng)為加(jia)強(qiang)圈”，加(jia)強(qiang)斷面(mian)的管(guan)片安裝工序(xu)。
