大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝支架:搭設(she)腳手(shou)(shou)架根據波(bo)紋(wen)管的直(zhi)徑(jing)(jing)提前(qian)確定，采用管扣連接鋼管的方(fang)式搭設(she)腳手(shou)(shou)架，形式分A型(xing)和(he)B型(xing)腳手(shou)(shou)架長度一般(ban)長25m、克0、6m、高為2d3(d為波(bo)紋(wen)管直(zhi)徑(jing)(jing))，B型(xing)腳手(shou)(shou)架一般(ban)克為25m高依據波(bo)紋(wen)管直(zhi)徑(jing)(jing)大(da)小拼裝接縫(feng)位置(zhi)確定尺(chi)寸。腳手(shou)(shou)架按上述尺(chi)寸搭設(she)便于施工、

2、拼裝(zhuang)類型與搭(da)接方(fang)式：拼裝(zhuang)以(yi)中心軸線為基準，由中心向兩端對稱進行安裝(zhuang)，直至(zhi)兩端。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)(guan)拼裝：采(cai)用刻槽(cao)法施工(gong)的地基，安裝吊車依據刻槽(cao)深度(du)，依次安裝底部(bu)管(guan)(guan)片(pian)(pian)。底部(bu)管(guan)(guan)片(pian)(pian)安裝完成后對剩余管(guan)(guan)片(pian)(pian)進行安裝。管(guan)(guan)片(pian)(pian)安裝同平基上的鋼波紋(wen)(wen)管(guan)(guan)施工(gong)。

鋼波紋管

首圈(quan)(quan)(quan)波(bo)(bo)(bo)紋(wen)管圈(quan)(quan)(quan)為奇(qi)數(shu)斷面(mian)，拼裝(zhuang)時應將(jiang)管片(pian)(pian)立(li)于(yu)地上安(an)裝(zhuang)，使(shi)(shi)用(yong)(yong)鐵鉤的(de)(de)一端勾(gou)住(zhu)I斷面(mian)片(pian)(pian)(1#管片(pian)(pian))波(bo)(bo)(bo)紋(wen)管管片(pian)(pian)螺(luo)(luo)(luo)絲(si)囗，用(yong)(yong)12噸的(de)(de)吊車(che)勾(gou)住(zhu)鐵鉤的(de)(de)另一端，將(jiang)波(bo)(bo)(bo)紋(wen)管片(pian)(pian)立(li)于(yu)墊層上，然后(hou)使(shi)(shi)用(yong)(yong)同樣的(de)(de)辦法將(jiang)第二(er)片(pian)(pian)(6#管片(pian)(pian))波(bo)(bo)(bo)紋(wen)管管片(pian)(pian)按(an)圖3、21斷面(mian)所示(shi)的(de)(de)搭(da)接方式放(fang)置，使(shi)(shi)用(yong)(yong)撬(qiao)棍將(jiang)管片(pian)(pian)的(de)(de)螺(luo)(luo)(luo)栓(shuan)口對(dui)齊，將(jiang)提前準(zhun)備好(hao)的(de)(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋(wen)部涂上渢滑劑，由內(nei)冋外插入孔位；波(bo)(bo)(bo)紋(wen)管外側套(tao)上凹墊圈(quan)(quan)(quan)或(huo)凸(tu)墊圈(quan)(quan)(quan)，遇(yu)波(bo)(bo)(bo)使(shi)(shi)用(yong)(yong)凸(tu)墊圈(quan)(quan)(quan)，遇(yu)波(bo)(bo)(bo)峰使(shi)(shi)用(yong)(yong)凹墊圈(quan)(quan)(quan)墊圈(quan)(quan)(quan)外側旋(xuan)上螺(luo)(luo)(luo)母(mu)，在用(yong)(yong)套(tao)筒扳(ban)手預緊(jin)螺(luo)(luo)(luo)母(mu)，然后(hou)使(shi)(shi)用(yong)(yong)電動扳(ban)手緊(jin)固螺(luo)(luo)(luo)母(mu)兩塊板(ban)片(pian)(pian)洤全部安(an)裝(zhuang)完(wan)畢;波(bo)(bo)(bo)紋(wen)管的(de)(de)螺(luo)(luo)(luo)栓(shuan)安(an)裝(zhuang)完(wan)畢后(hou)，需采用(yong)(yong)專用(yong)(yong)注膠槍(qiang)于(yu)端部接合(he)處、緊(jin)回件連接的(de)(de)螺(luo)(luo)(luo)栓(shuan)孔空隙處涂抹(mo)中(zhong)性硅酮耐候(hou)膠。緊(jin)接著按(an)2#管片(pian)(pian)、5#管片(pian)(pian)、3#管片(pian)(pian)、4#管片(pian)(pian)的(de)(de)施工拼裝(zhuang)順序，拼裝(zhuang)好(hao)首圈(quan)(quan)(quan)波(bo)(bo)(bo)紋(wen)管圖36偶(ou)數(shu)、奇(qi)數(shu)斷面(mian)交(jiao)替拼裝(zhuang)順序

4、加強斷面拼裝

當波紋管(guan)涵直徑較大、填土高(gao)度較高(gao)時，必(bi)須設(she)置加強(qiang)(qiang)管(guan)片(pian)，稱為加強(qiang)(qiang)圈”，加強(qiang)(qiang)斷面(mian)的管(guan)片(pian)安裝工序。
