2、拼裝(zhuang)類(lei)型(xing)與(yu)搭接方式：拼裝(zhuang)以中心軸線為基準，由中心向(xiang)兩端(duan)對稱進行安裝(zhuang)，直(zhi)至兩端(duan)。1斷面(奇數(shu)斷面)、Ⅱ斷面(偶(ou)數(shu)斷面)、加強斷面(偶(ou)數(shu)斷管(guan)管(guan)片）

3、波紋管(guan)(guan)拼裝：采(cai)用刻槽(cao)法施工的(de)地基，安(an)裝吊車依(yi)據刻槽(cao)深度(du)，依(yi)次安(an)裝底部管(guan)(guan)片。底部管(guan)(guan)片安(an)裝完成(cheng)后對剩余管(guan)(guan)片進行(xing)安(an)裝。管(guan)(guan)片安(an)裝同平基上的(de)鋼波紋管(guan)(guan)施工。

鋼波紋管

首圈(quan)(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)圈(quan)(quan)為奇數斷(duan)面，拼裝(zhuang)(zhuang)時應將管(guan)(guan)(guan)片(pian)立(li)(li)于地上安裝(zhuang)(zhuang)，使(shi)用(yong)(yong)鐵(tie)鉤(gou)的(de)一端勾(gou)住I斷(duan)面片(pian)(1#管(guan)(guan)(guan)片(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)螺(luo)絲囗，用(yong)(yong)12噸的(de)吊車勾(gou)住鐵(tie)鉤(gou)的(de)另一端，將波(bo)(bo)紋(wen)管(guan)(guan)(guan)片(pian)立(li)(li)于墊(dian)(dian)層上，然后使(shi)用(yong)(yong)同樣的(de)辦法將第二(er)片(pian)(6#管(guan)(guan)(guan)片(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)按圖3、21斷(duan)面所示的(de)搭接方式放置，使(shi)用(yong)(yong)撬棍將管(guan)(guan)(guan)片(pian)的(de)螺(luo)栓口對齊，將提(ti)前準備好(hao)的(de)螺(luo)栓螺(luo)紋(wen)部(bu)(bu)(bu)涂上渢滑劑，由內冋外插入孔(kong)位；波(bo)(bo)紋(wen)管(guan)(guan)(guan)外側(ce)套上凹墊(dian)(dian)圈(quan)(quan)或(huo)凸墊(dian)(dian)圈(quan)(quan)，遇(yu)波(bo)(bo)使(shi)用(yong)(yong)凸墊(dian)(dian)圈(quan)(quan)，遇(yu)波(bo)(bo)峰(feng)使(shi)用(yong)(yong)凹墊(dian)(dian)圈(quan)(quan)墊(dian)(dian)圈(quan)(quan)外側(ce)旋上螺(luo)母(mu)(mu)，在用(yong)(yong)套筒扳手預緊(jin)(jin)(jin)螺(luo)母(mu)(mu)，然后使(shi)用(yong)(yong)電(dian)動扳手緊(jin)(jin)(jin)固螺(luo)母(mu)(mu)兩塊板片(pian)洤全部(bu)(bu)(bu)安裝(zhuang)(zhuang)完畢;波(bo)(bo)紋(wen)管(guan)(guan)(guan)的(de)螺(luo)栓安裝(zhuang)(zhuang)完畢后，需采用(yong)(yong)專用(yong)(yong)注膠槍于端部(bu)(bu)(bu)接合處、緊(jin)(jin)(jin)回件(jian)連(lian)接的(de)螺(luo)栓孔(kong)空隙處涂抹中性硅酮耐候(hou)膠。緊(jin)(jin)(jin)接著按2#管(guan)(guan)(guan)片(pian)、5#管(guan)(guan)(guan)片(pian)、3#管(guan)(guan)(guan)片(pian)、4#管(guan)(guan)(guan)片(pian)的(de)施(shi)工拼裝(zhuang)(zhuang)順序，拼裝(zhuang)(zhuang)好(hao)首圈(quan)(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)圖36偶數、奇數斷(duan)面交替(ti)拼裝(zhuang)(zhuang)順序

4、加強斷面拼裝

當波紋管涵直徑較大、填土高度較高時，必須設置加強管片，稱為加強圈”，加強斷面的管片安裝工(gong)序。
