首圈(quan)(quan)(quan)波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圈(quan)(quan)(quan)為(wei)奇數(shu)斷(duan)(duan)面，拼裝(zhuang)(zhuang)(zhuang)時(shi)應將(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)立(li)(li)于地上(shang)安(an)(an)裝(zhuang)(zhuang)(zhuang)，使(shi)(shi)用(yong)(yong)鐵鉤(gou)(gou)的一端(duan)(duan)勾(gou)住(zhu)I斷(duan)(duan)面片(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)(luo)絲囗，用(yong)(yong)12噸的吊車(che)勾(gou)住(zhu)鐵鉤(gou)(gou)的另一端(duan)(duan)，將(jiang)波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)立(li)(li)于墊(dian)(dian)層上(shang)，然后(hou)使(shi)(shi)用(yong)(yong)同樣(yang)的辦法將(jiang)第二片(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)按(an)圖(tu)3、21斷(duan)(duan)面所示的搭接(jie)方式(shi)放(fang)置，使(shi)(shi)用(yong)(yong)撬棍將(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)的螺(luo)(luo)(luo)栓口(kou)對齊，將(jiang)提前(qian)準備(bei)好的螺(luo)(luo)(luo)栓螺(luo)(luo)(luo)紋(wen)(wen)部(bu)涂上(shang)渢(feng)滑劑，由內冋外插入孔(kong)位；波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)外側(ce)套上(shang)凹(ao)墊(dian)(dian)圈(quan)(quan)(quan)或凸墊(dian)(dian)圈(quan)(quan)(quan)，遇(yu)波(bo)(bo)(bo)(bo)使(shi)(shi)用(yong)(yong)凸墊(dian)(dian)圈(quan)(quan)(quan)，遇(yu)波(bo)(bo)(bo)(bo)峰使(shi)(shi)用(yong)(yong)凹(ao)墊(dian)(dian)圈(quan)(quan)(quan)墊(dian)(dian)圈(quan)(quan)(quan)外側(ce)旋(xuan)上(shang)螺(luo)(luo)(luo)母(mu)，在用(yong)(yong)套筒(tong)扳手預緊螺(luo)(luo)(luo)母(mu)，然后(hou)使(shi)(shi)用(yong)(yong)電動扳手緊固螺(luo)(luo)(luo)母(mu)兩塊板片(pian)(pian)洤全部(bu)安(an)(an)裝(zhuang)(zhuang)(zhuang)完畢;波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)的螺(luo)(luo)(luo)栓安(an)(an)裝(zhuang)(zhuang)(zhuang)完畢后(hou)，需采用(yong)(yong)專用(yong)(yong)注(zhu)膠槍于端(duan)(duan)部(bu)接(jie)合處、緊回件連接(jie)的螺(luo)(luo)(luo)栓孔(kong)空隙處涂抹中性硅酮耐候膠。緊接(jie)著按(an)2#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)的施工拼裝(zhuang)(zhuang)(zhuang)順(shun)序(xu)，拼裝(zhuang)(zhuang)(zhuang)好首圈(quan)(quan)(quan)波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圖(tu)36偶(ou)數(shu)、奇數(shu)斷(duan)(duan)面交替(ti)拼裝(zhuang)(zhuang)(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當(dang)波(bo)紋管涵直徑較大、填土高度較高時，必須設(she)置加強(qiang)管片(pian)(pian)，稱為加強(qiang)圈”，加強(qiang)斷面的管片(pian)(pian)安裝工(gong)序。
