2、拼裝(zhuang)類(lei)型(xing)與搭(da)接方式：拼裝(zhuang)以中心(xin)軸線為基準，由中心(xin)向兩端對稱進(jin)行安裝(zhuang)，直至兩端。1斷面(mian)(奇數斷面(mian))、Ⅱ斷面(mian)(偶數斷面(mian))、加強斷面(mian)(偶數斷管(guan)管(guan)片）

3、波(bo)紋管(guan)拼裝：采用刻槽(cao)法(fa)施工的(de)地基(ji)，安(an)裝吊車依據刻槽(cao)深度(du)，依次安(an)裝底部(bu)管(guan)片(pian)(pian)。底部(bu)管(guan)片(pian)(pian)安(an)裝完(wan)成后對剩余管(guan)片(pian)(pian)進行安(an)裝。管(guan)片(pian)(pian)安(an)裝同平基(ji)上的(de)鋼波(bo)紋管(guan)施工。

鋼波紋管

首圈(quan)(quan)波紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)圈(quan)(quan)為奇(qi)數斷(duan)面(mian)(mian)，拼裝(zhuang)時應將(jiang)(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)立于地上安裝(zhuang)，使(shi)用(yong)(yong)鐵鉤(gou)的(de)一(yi)(yi)端勾住I斷(duan)面(mian)(mian)片(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian))波紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)螺(luo)絲囗，用(yong)(yong)12噸(dun)的(de)吊車勾住鐵鉤(gou)的(de)另一(yi)(yi)端，將(jiang)(jiang)波紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)立于墊(dian)層上，然(ran)(ran)后(hou)使(shi)用(yong)(yong)同樣的(de)辦(ban)法將(jiang)(jiang)第(di)二片(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian))波紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)按(an)圖3、21斷(duan)面(mian)(mian)所示(shi)的(de)搭接方式(shi)放置，使(shi)用(yong)(yong)撬棍將(jiang)(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)的(de)螺(luo)栓口(kou)對齊，將(jiang)(jiang)提前準備好的(de)螺(luo)栓螺(luo)紋(wen)(wen)(wen)部(bu)涂上渢滑劑，由內冋外(wai)插入孔位(wei)；波紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)外(wai)側套上凹墊(dian)圈(quan)(quan)或凸(tu)墊(dian)圈(quan)(quan)，遇波使(shi)用(yong)(yong)凸(tu)墊(dian)圈(quan)(quan)，遇波峰(feng)使(shi)用(yong)(yong)凹墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外(wai)側旋(xuan)上螺(luo)母，在用(yong)(yong)套筒扳手(shou)預緊(jin)螺(luo)母，然(ran)(ran)后(hou)使(shi)用(yong)(yong)電(dian)動扳手(shou)緊(jin)固螺(luo)母兩(liang)塊(kuai)板片(pian)(pian)洤全(quan)部(bu)安裝(zhuang)完畢;波紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)的(de)螺(luo)栓安裝(zhuang)完畢后(hou)，需采用(yong)(yong)專用(yong)(yong)注膠槍于端部(bu)接合(he)處(chu)、緊(jin)回件連接的(de)螺(luo)栓孔空(kong)隙處(chu)涂抹中(zhong)性硅(gui)酮耐候(hou)膠。緊(jin)接著按(an)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(shi)工(gong)拼裝(zhuang)順序，拼裝(zhuang)好首圈(quan)(quan)波紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)圖36偶數、奇(qi)數斷(duan)面(mian)(mian)交替拼裝(zhuang)順序

4、加強斷面拼裝

當波(bo)紋管涵直徑較大、填(tian)土高(gao)度較高(gao)時(shi)，必須設置加(jia)強(qiang)(qiang)管片，稱為(wei)加(jia)強(qiang)(qiang)圈”，加(jia)強(qiang)(qiang)斷面的管片安裝工序。
