首圈(quan)(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)圈(quan)(quan)為奇數斷(duan)(duan)面(mian)(mian)，拼裝(zhuang)(zhuang)時應(ying)將(jiang)管(guan)(guan)(guan)片(pian)(pian)(pian)立于地上(shang)(shang)(shang)安裝(zhuang)(zhuang)，使(shi)(shi)用(yong)(yong)(yong)(yong)鐵鉤的(de)(de)一(yi)端勾住I斷(duan)(duan)面(mian)(mian)片(pian)(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)(yong)(yong)12噸(dun)的(de)(de)吊車勾住鐵鉤的(de)(de)另一(yi)端，將(jiang)波(bo)紋(wen)(wen)管(guan)(guan)(guan)片(pian)(pian)(pian)立于墊(dian)(dian)層上(shang)(shang)(shang)，然后(hou)使(shi)(shi)用(yong)(yong)(yong)(yong)同樣的(de)(de)辦法將(jiang)第二(er)片(pian)(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)按圖3、21斷(duan)(duan)面(mian)(mian)所示(shi)的(de)(de)搭接方式放置，使(shi)(shi)用(yong)(yong)(yong)(yong)撬棍將(jiang)管(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)螺(luo)(luo)栓口對齊，將(jiang)提前(qian)準備好的(de)(de)螺(luo)(luo)栓螺(luo)(luo)紋(wen)(wen)部涂上(shang)(shang)(shang)渢滑劑，由內冋外插入(ru)孔位；波(bo)紋(wen)(wen)管(guan)(guan)(guan)外側(ce)套上(shang)(shang)(shang)凹墊(dian)(dian)圈(quan)(quan)或凸(tu)墊(dian)(dian)圈(quan)(quan)，遇波(bo)使(shi)(shi)用(yong)(yong)(yong)(yong)凸(tu)墊(dian)(dian)圈(quan)(quan)，遇波(bo)峰使(shi)(shi)用(yong)(yong)(yong)(yong)凹墊(dian)(dian)圈(quan)(quan)墊(dian)(dian)圈(quan)(quan)外側(ce)旋上(shang)(shang)(shang)螺(luo)(luo)母，在用(yong)(yong)(yong)(yong)套筒扳手預緊螺(luo)(luo)母，然后(hou)使(shi)(shi)用(yong)(yong)(yong)(yong)電動扳手緊固螺(luo)(luo)母兩塊板片(pian)(pian)(pian)洤全部安裝(zhuang)(zhuang)完畢;波(bo)紋(wen)(wen)管(guan)(guan)(guan)的(de)(de)螺(luo)(luo)栓安裝(zhuang)(zhuang)完畢后(hou)，需采(cai)用(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)注膠槍于端部接合處(chu)、緊回件連接的(de)(de)螺(luo)(luo)栓孔空隙處(chu)涂抹(mo)中性硅酮耐候膠。緊接著按2#管(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)施工拼裝(zhuang)(zhuang)順(shun)序，拼裝(zhuang)(zhuang)好首圈(quan)(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)圖36偶數、奇數斷(duan)(duan)面(mian)(mian)交替拼裝(zhuang)(zhuang)順(shun)序

4、加強斷面拼裝

當波紋(wen)管(guan)涵直(zhi)徑較大、填土高度較高時，必須設置加(jia)強(qiang)管(guan)片，稱為(wei)加(jia)強(qiang)圈”，加(jia)強(qiang)斷面的管(guan)片安裝工序。
