大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝支(zhi)架(jia)(jia):搭設(she)腳手(shou)架(jia)(jia)根(gen)據(ju)波(bo)(bo)紋管(guan)(guan)的直徑提前(qian)確(que)定，采用管(guan)(guan)扣連接(jie)鋼(gang)管(guan)(guan)的方式(shi)搭設(she)腳手(shou)架(jia)(jia)，形式(shi)分A型和B型腳手(shou)架(jia)(jia)長度一般(ban)長25m、克(ke)0、6m、高為2d3(d為波(bo)(bo)紋管(guan)(guan)直徑)，B型腳手(shou)架(jia)(jia)一般(ban)克(ke)為25m高依據(ju)波(bo)(bo)紋管(guan)(guan)直徑大小拼裝接(jie)縫位置確(que)定尺寸。腳手(shou)架(jia)(jia)按(an)上述尺寸搭設(she)便于施工、

2、拼裝(zhuang)類型與搭接方式：拼裝(zhuang)以(yi)中心(xin)(xin)軸線為基(ji)準(zhun)，由中心(xin)(xin)向(xiang)兩(liang)端對稱進行安(an)裝(zhuang)，直至(zhi)兩(liang)端。1斷(duan)面(mian)(奇數(shu)(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數(shu)(shu)斷(duan)面(mian))、加強斷(duan)面(mian)(偶數(shu)(shu)斷(duan)管管片）

3、波紋(wen)(wen)管(guan)拼(pin)裝：采用刻(ke)槽(cao)法施工的(de)地基，安(an)(an)裝吊車依據刻(ke)槽(cao)深度，依次安(an)(an)裝底部(bu)管(guan)片。底部(bu)管(guan)片安(an)(an)裝完成后對剩余管(guan)片進行安(an)(an)裝。管(guan)片安(an)(an)裝同平基上(shang)的(de)鋼波紋(wen)(wen)管(guan)施工。

首圈(quan)波(bo)紋(wen)(wen)管(guan)(guan)圈(quan)為奇數(shu)斷(duan)面(mian)，拼(pin)(pin)裝時應(ying)將(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)(yu)地上(shang)安(an)裝，使用(yong)(yong)(yong)鐵鉤(gou)的(de)(de)(de)(de)一端(duan)勾(gou)(gou)住I斷(duan)面(mian)片(pian)(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)螺絲囗，用(yong)(yong)(yong)12噸的(de)(de)(de)(de)吊車勾(gou)(gou)住鐵鉤(gou)的(de)(de)(de)(de)另一端(duan)，將(jiang)波(bo)紋(wen)(wen)管(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)(yu)墊(dian)層上(shang)，然后使用(yong)(yong)(yong)同樣的(de)(de)(de)(de)辦法將(jiang)第二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)按圖(tu)3、21斷(duan)面(mian)所示的(de)(de)(de)(de)搭接方式放置，使用(yong)(yong)(yong)撬(qiao)棍將(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)(de)螺栓(shuan)口對齊，將(jiang)提(ti)前(qian)準備好的(de)(de)(de)(de)螺栓(shuan)螺紋(wen)(wen)部(bu)涂上(shang)渢滑(hua)劑，由(you)內冋外(wai)插(cha)入孔位(wei)；波(bo)紋(wen)(wen)管(guan)(guan)外(wai)側套上(shang)凹墊(dian)圈(quan)或凸墊(dian)圈(quan)，遇(yu)波(bo)使用(yong)(yong)(yong)凸墊(dian)圈(quan)，遇(yu)波(bo)峰使用(yong)(yong)(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外(wai)側旋上(shang)螺母(mu)，在用(yong)(yong)(yong)套筒扳手預緊(jin)(jin)螺母(mu)，然后使用(yong)(yong)(yong)電動扳手緊(jin)(jin)固螺母(mu)兩塊板片(pian)(pian)(pian)(pian)洤全部(bu)安(an)裝完畢;波(bo)紋(wen)(wen)管(guan)(guan)的(de)(de)(de)(de)螺栓(shuan)安(an)裝完畢后，需采用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠槍于(yu)(yu)端(duan)部(bu)接合處(chu)、緊(jin)(jin)回(hui)件連接的(de)(de)(de)(de)螺栓(shuan)孔空隙處(chu)涂抹(mo)中性硅酮耐候膠。緊(jin)(jin)接著按2#管(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)(de)施工拼(pin)(pin)裝順序，拼(pin)(pin)裝好首圈(quan)波(bo)紋(wen)(wen)管(guan)(guan)圖(tu)36偶數(shu)、奇數(shu)斷(duan)面(mian)交(jiao)替拼(pin)(pin)裝順序

4、加強斷面拼裝

當波紋管(guan)涵直徑較(jiao)大、填(tian)土高(gao)度較(jiao)高(gao)時，必須設(she)置加(jia)強管(guan)片(pian)，稱為加(jia)強圈(quan)”，加(jia)強斷(duan)面的管(guan)片(pian)安裝工序。
