大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝(zhuang)支(zhi)架(jia):搭設腳(jiao)手架(jia)根據(ju)波(bo)紋(wen)管(guan)的直(zhi)徑提前確(que)定(ding)，采用管(guan)扣連接(jie)鋼管(guan)的方式搭設腳(jiao)手架(jia)，形(xing)式分A型(xing)和(he)B型(xing)腳(jiao)手架(jia)長度一般(ban)長25m、克0、6m、高為2d3(d為波(bo)紋(wen)管(guan)直(zhi)徑)，B型(xing)腳(jiao)手架(jia)一般(ban)克為25m高依據(ju)波(bo)紋(wen)管(guan)直(zhi)徑大小拼(pin)裝(zhuang)接(jie)縫位置確(que)定(ding)尺(chi)寸(cun)。腳(jiao)手架(jia)按上述(shu)尺(chi)寸(cun)搭設便于施工、

2、拼裝(zhuang)(zhuang)類(lei)型與搭接方式：拼裝(zhuang)(zhuang)以中心軸線(xian)為基準，由中心向兩端對稱進行安裝(zhuang)(zhuang)，直(zhi)至兩端。1斷(duan)(duan)(duan)面(奇數(shu)斷(duan)(duan)(duan)面)、Ⅱ斷(duan)(duan)(duan)面(偶數(shu)斷(duan)(duan)(duan)面)、加強斷(duan)(duan)(duan)面(偶數(shu)斷(duan)(duan)(duan)管(guan)管(guan)片）

3、波紋管(guan)拼裝(zhuang)：采用刻槽法(fa)施工(gong)的(de)地基，安裝(zhuang)吊(diao)車(che)依(yi)(yi)據刻槽深度，依(yi)(yi)次安裝(zhuang)底部管(guan)片。底部管(guan)片安裝(zhuang)完成(cheng)后對(dui)剩余管(guan)片進行安裝(zhuang)。管(guan)片安裝(zhuang)同平基上的(de)鋼波紋管(guan)施工(gong)。

首圈(quan)(quan)波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)圈(quan)(quan)為奇數斷面，拼(pin)(pin)裝時應將(jiang)管(guan)(guan)(guan)片(pian)(pian)立(li)于地上(shang)(shang)安裝，使(shi)用(yong)(yong)鐵(tie)鉤的(de)(de)一端勾住I斷面片(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)絲(si)囗，用(yong)(yong)12噸的(de)(de)吊(diao)車勾住鐵(tie)鉤的(de)(de)另一端，將(jiang)波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)片(pian)(pian)立(li)于墊(dian)(dian)層上(shang)(shang)，然后(hou)(hou)使(shi)用(yong)(yong)同(tong)樣的(de)(de)辦法將(jiang)第(di)二(er)片(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)按圖3、21斷面所示的(de)(de)搭接方式(shi)放置，使(shi)用(yong)(yong)撬(qiao)棍(gun)將(jiang)管(guan)(guan)(guan)片(pian)(pian)的(de)(de)螺(luo)(luo)栓(shuan)口對齊(qi)，將(jiang)提前準備好(hao)的(de)(de)螺(luo)(luo)栓(shuan)螺(luo)(luo)紋(wen)(wen)部涂上(shang)(shang)渢滑劑，由內冋外(wai)插入孔(kong)位；波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)外(wai)側(ce)套(tao)上(shang)(shang)凹(ao)墊(dian)(dian)圈(quan)(quan)或凸墊(dian)(dian)圈(quan)(quan)，遇波(bo)(bo)(bo)(bo)使(shi)用(yong)(yong)凸墊(dian)(dian)圈(quan)(quan)，遇波(bo)(bo)(bo)(bo)峰(feng)使(shi)用(yong)(yong)凹(ao)墊(dian)(dian)圈(quan)(quan)墊(dian)(dian)圈(quan)(quan)外(wai)側(ce)旋上(shang)(shang)螺(luo)(luo)母(mu)(mu)，在用(yong)(yong)套(tao)筒(tong)扳(ban)手預緊(jin)螺(luo)(luo)母(mu)(mu)，然后(hou)(hou)使(shi)用(yong)(yong)電(dian)動扳(ban)手緊(jin)固螺(luo)(luo)母(mu)(mu)兩塊板片(pian)(pian)洤全部安裝完畢;波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)的(de)(de)螺(luo)(luo)栓(shuan)安裝完畢后(hou)(hou)，需采(cai)用(yong)(yong)專用(yong)(yong)注膠槍(qiang)于端部接合處、緊(jin)回件連(lian)接的(de)(de)螺(luo)(luo)栓(shuan)孔(kong)空隙處涂抹中(zhong)性硅酮耐候膠。緊(jin)接著按2#管(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)的(de)(de)施(shi)工拼(pin)(pin)裝順(shun)序，拼(pin)(pin)裝好(hao)首圈(quan)(quan)波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)圖36偶數、奇數斷面交(jiao)替拼(pin)(pin)裝順(shun)序

4、加強斷面拼裝

當波紋管涵直(zhi)徑較(jiao)大、填土高度較(jiao)高時，必須設置加強(qiang)管片(pian)，稱為加強(qiang)圈”，加強(qiang)斷面的管片(pian)安(an)裝(zhuang)工序。
