首(shou)圈(quan)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)圈(quan)為奇數斷面(mian)，拼裝(zhuang)(zhuang)時應(ying)將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)立于地(di)上(shang)安(an)裝(zhuang)(zhuang)，使(shi)用鐵鉤(gou)的(de)(de)(de)(de)一端(duan)勾住I斷面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)螺(luo)絲囗，用12噸(dun)的(de)(de)(de)(de)吊車勾住鐵鉤(gou)的(de)(de)(de)(de)另一端(duan)，將(jiang)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)立于墊(dian)層(ceng)上(shang)，然后(hou)使(shi)用同樣(yang)的(de)(de)(de)(de)辦法將(jiang)第(di)二(er)片(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)按圖3、21斷面(mian)所示的(de)(de)(de)(de)搭接(jie)方式放置，使(shi)用撬棍將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)的(de)(de)(de)(de)螺(luo)栓(shuan)口對齊，將(jiang)提前準備好的(de)(de)(de)(de)螺(luo)栓(shuan)螺(luo)紋(wen)(wen)部涂上(shang)渢滑劑，由內冋外插入(ru)孔位；波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)外側(ce)套上(shang)凹墊(dian)圈(quan)或凸(tu)墊(dian)圈(quan)，遇(yu)波(bo)(bo)(bo)使(shi)用凸(tu)墊(dian)圈(quan)，遇(yu)波(bo)(bo)(bo)峰使(shi)用凹墊(dian)圈(quan)墊(dian)圈(quan)外側(ce)旋上(shang)螺(luo)母(mu)，在用套筒扳(ban)手預緊(jin)螺(luo)母(mu)，然后(hou)使(shi)用電動扳(ban)手緊(jin)固螺(luo)母(mu)兩塊板片(pian)(pian)洤全部安(an)裝(zhuang)(zhuang)完畢;波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)螺(luo)栓(shuan)安(an)裝(zhuang)(zhuang)完畢后(hou)，需(xu)采用專用注膠槍(qiang)于端(duan)部接(jie)合處、緊(jin)回件連接(jie)的(de)(de)(de)(de)螺(luo)栓(shuan)孔空隙處涂抹中性硅酮耐候(hou)膠。緊(jin)接(jie)著(zhu)按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)(de)(de)(de)施工(gong)拼裝(zhuang)(zhuang)順(shun)序(xu)(xu)，拼裝(zhuang)(zhuang)好首(shou)圈(quan)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)圖36偶數、奇數斷面(mian)交(jiao)替(ti)拼裝(zhuang)(zhuang)順(shun)序(xu)(xu)

4、加強斷面拼裝

當波(bo)紋管涵直徑較(jiao)大(da)、填土高(gao)度較(jiao)高(gao)時，必須(xu)設置加(jia)強(qiang)(qiang)管片，稱為(wei)加(jia)強(qiang)(qiang)圈(quan)”，加(jia)強(qiang)(qiang)斷面的管片安裝工序。
