大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼(pin)裝(zhuang)支(zhi)架(jia)(jia):搭(da)(da)設腳手(shou)架(jia)(jia)根(gen)據(ju)波(bo)紋(wen)管(guan)(guan)的直(zhi)徑提(ti)前(qian)確定(ding)，采用管(guan)(guan)扣連接(jie)鋼管(guan)(guan)的方式(shi)搭(da)(da)設腳手(shou)架(jia)(jia)，形式(shi)分A型(xing)和(he)B型(xing)腳手(shou)架(jia)(jia)長度(du)一(yi)般(ban)長25m、克0、6m、高為(wei)(wei)2d3(d為(wei)(wei)波(bo)紋(wen)管(guan)(guan)直(zhi)徑)，B型(xing)腳手(shou)架(jia)(jia)一(yi)般(ban)克為(wei)(wei)25m高依(yi)據(ju)波(bo)紋(wen)管(guan)(guan)直(zhi)徑大(da)小拼(pin)裝(zhuang)接(jie)縫位置確定(ding)尺寸(cun)。腳手(shou)架(jia)(jia)按上述尺寸(cun)搭(da)(da)設便于施工、

2、拼(pin)裝(zhuang)類型(xing)與搭(da)接(jie)方(fang)式：拼(pin)裝(zhuang)以中心軸線為基(ji)準，由中心向兩端對稱進行安裝(zhuang)，直(zhi)至兩端。1斷(duan)面(奇數(shu)斷(duan)面)、Ⅱ斷(duan)面(偶(ou)數(shu)斷(duan)面)、加強斷(duan)面(偶(ou)數(shu)斷(duan)管(guan)(guan)管(guan)(guan)片）

3、波(bo)紋(wen)管(guan)(guan)(guan)拼(pin)裝(zhuang)(zhuang)：采用(yong)刻(ke)槽(cao)法施工的(de)地基，安(an)(an)裝(zhuang)(zhuang)吊(diao)車(che)依(yi)據刻(ke)槽(cao)深度，依(yi)次安(an)(an)裝(zhuang)(zhuang)底(di)部(bu)管(guan)(guan)(guan)片。底(di)部(bu)管(guan)(guan)(guan)片安(an)(an)裝(zhuang)(zhuang)完(wan)成后對剩余(yu)管(guan)(guan)(guan)片進行安(an)(an)裝(zhuang)(zhuang)。管(guan)(guan)(guan)片安(an)(an)裝(zhuang)(zhuang)同平基上的(de)鋼波(bo)紋(wen)管(guan)(guan)(guan)施工。

首圈(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)圈(quan)為(wei)奇數(shu)斷面(mian)，拼(pin)裝(zhuang)時應將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)立于地上安裝(zhuang)，使用(yong)(yong)(yong)鐵鉤(gou)的(de)一(yi)端(duan)勾住I斷面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)螺(luo)絲(si)囗，用(yong)(yong)(yong)12噸的(de)吊車勾住鐵鉤(gou)的(de)另(ling)一(yi)端(duan)，將(jiang)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)立于墊(dian)(dian)層上，然(ran)后使用(yong)(yong)(yong)同(tong)樣的(de)辦法將(jiang)第二片(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)按圖(tu)3、21斷面(mian)所示的(de)搭接方式(shi)放置，使用(yong)(yong)(yong)撬棍將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)的(de)螺(luo)栓口對齊，將(jiang)提前準(zhun)備好(hao)的(de)螺(luo)栓螺(luo)紋(wen)(wen)部涂上渢滑劑，由內冋外(wai)插入孔位；波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)外(wai)側套上凹墊(dian)(dian)圈(quan)或凸(tu)墊(dian)(dian)圈(quan)，遇波(bo)使用(yong)(yong)(yong)凸(tu)墊(dian)(dian)圈(quan)，遇波(bo)峰(feng)使用(yong)(yong)(yong)凹墊(dian)(dian)圈(quan)墊(dian)(dian)圈(quan)外(wai)側旋上螺(luo)母，在用(yong)(yong)(yong)套筒扳手(shou)預(yu)緊(jin)螺(luo)母，然(ran)后使用(yong)(yong)(yong)電動(dong)扳手(shou)緊(jin)固螺(luo)母兩塊板片(pian)(pian)洤全部安裝(zhuang)完(wan)畢;波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)的(de)螺(luo)栓安裝(zhuang)完(wan)畢后，需(xu)采用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠槍于端(duan)部接合處、緊(jin)回(hui)件(jian)連接的(de)螺(luo)栓孔空隙處涂抹(mo)中性硅(gui)酮(tong)耐候(hou)膠。緊(jin)接著按2#管(guan)(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)的(de)施工拼(pin)裝(zhuang)順(shun)序，拼(pin)裝(zhuang)好(hao)首圈(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)圖(tu)36偶數(shu)、奇數(shu)斷面(mian)交替(ti)拼(pin)裝(zhuang)順(shun)序

4、加強斷面拼裝

當波紋管(guan)涵直徑較(jiao)大、填土高(gao)度較(jiao)高(gao)時，必須設(she)置加強管(guan)片，稱為加強圈”，加強斷(duan)面的管(guan)片安裝(zhuang)工(gong)序。
