大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)拼裝(zhuang)支(zhi)架(jia)(jia):搭(da)(da)設(she)腳(jiao)手架(jia)(jia)根(gen)據波(bo)紋(wen)管(guan)的直(zhi)徑提前確定(ding)，采用(yong)管(guan)扣連接鋼(gang)管(guan)的方(fang)式搭(da)(da)設(she)腳(jiao)手架(jia)(jia)，形式分A型和(he)B型腳(jiao)手架(jia)(jia)長(chang)度(du)一般長(chang)25m、克0、6m、高(gao)為2d3(d為波(bo)紋(wen)管(guan)直(zhi)徑)，B型腳(jiao)手架(jia)(jia)一般克為25m高(gao)依(yi)據波(bo)紋(wen)管(guan)直(zhi)徑大小拼裝(zhuang)接縫位置確定(ding)尺(chi)寸(cun)。腳(jiao)手架(jia)(jia)按上(shang)述尺(chi)寸(cun)搭(da)(da)設(she)便于(yu)施工、

2、拼(pin)裝(zhuang)類(lei)型與搭接方式：拼(pin)裝(zhuang)以中心(xin)軸(zhou)線為基(ji)準(zhun)，由中心(xin)向兩(liang)端對(dui)稱進行(xing)安裝(zhuang)，直至兩(liang)端。1斷(duan)(duan)面(mian)(奇數斷(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)面(mian)(偶(ou)數斷(duan)(duan)面(mian))、加(jia)強(qiang)斷(duan)(duan)面(mian)(偶(ou)數斷(duan)(duan)管(guan)管(guan)片）

3、波紋管(guan)(guan)(guan)拼裝(zhuang)：采用(yong)刻(ke)槽法施(shi)工的(de)(de)地基(ji)，安裝(zhuang)吊(diao)車依(yi)據刻(ke)槽深度，依(yi)次安裝(zhuang)底部(bu)管(guan)(guan)(guan)片(pian)。底部(bu)管(guan)(guan)(guan)片(pian)安裝(zhuang)完(wan)成后(hou)對剩余管(guan)(guan)(guan)片(pian)進行安裝(zhuang)。管(guan)(guan)(guan)片(pian)安裝(zhuang)同平基(ji)上的(de)(de)鋼波紋管(guan)(guan)(guan)施(shi)工。

首圈波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)圈為奇數斷面，拼(pin)裝(zhuang)(zhuang)(zhuang)時應將(jiang)(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立(li)于地上安(an)裝(zhuang)(zhuang)(zhuang)，使(shi)用(yong)(yong)鐵鉤的(de)一端勾(gou)住I斷面片(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)絲囗，用(yong)(yong)12噸的(de)吊車勾(gou)住鐵鉤的(de)另一端，將(jiang)(jiang)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立(li)于墊層上，然(ran)后使(shi)用(yong)(yong)同樣的(de)辦法將(jiang)(jiang)第二片(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)按(an)圖3、21斷面所示(shi)的(de)搭(da)接方式放置，使(shi)用(yong)(yong)撬(qiao)棍將(jiang)(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)螺(luo)栓口對齊(qi)，將(jiang)(jiang)提前準(zhun)備好的(de)螺(luo)栓螺(luo)紋(wen)(wen)(wen)部(bu)涂上渢滑劑，由內(nei)冋(jiong)外插(cha)入孔位；波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)外側套(tao)上凹墊圈或(huo)凸墊圈，遇波(bo)(bo)(bo)使(shi)用(yong)(yong)凸墊圈，遇波(bo)(bo)(bo)峰使(shi)用(yong)(yong)凹墊圈墊圈外側旋上螺(luo)母，在用(yong)(yong)套(tao)筒扳手(shou)預緊(jin)螺(luo)母，然(ran)后使(shi)用(yong)(yong)電動扳手(shou)緊(jin)固螺(luo)母兩塊板片(pian)(pian)(pian)洤(quan)全(quan)部(bu)安(an)裝(zhuang)(zhuang)(zhuang)完(wan)畢;波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)的(de)螺(luo)栓安(an)裝(zhuang)(zhuang)(zhuang)完(wan)畢后，需(xu)采用(yong)(yong)專(zhuan)用(yong)(yong)注膠槍于端部(bu)接合處(chu)、緊(jin)回件連接的(de)螺(luo)栓孔空隙處(chu)涂抹(mo)中性硅酮耐候膠。緊(jin)接著按(an)2#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)施工拼(pin)裝(zhuang)(zhuang)(zhuang)順序(xu)，拼(pin)裝(zhuang)(zhuang)(zhuang)好首圈波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)圖36偶(ou)數、奇數斷面交替拼(pin)裝(zhuang)(zhuang)(zhuang)順序(xu)

4、加強斷面拼裝

當波紋管涵直徑(jing)較大、填土高度較高時，必(bi)須設置加(jia)強管片，稱為加(jia)強圈”，加(jia)強斷面的管片安裝工序。
