大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼裝支(zhi)架(jia):搭(da)設腳(jiao)(jiao)手(shou)(shou)架(jia)根(gen)據(ju)波(bo)紋管(guan)(guan)的直徑(jing)提前確(que)定(ding)，采(cai)用(yong)管(guan)(guan)扣連接(jie)鋼管(guan)(guan)的方(fang)式(shi)搭(da)設腳(jiao)(jiao)手(shou)(shou)架(jia)，形式(shi)分A型(xing)和B型(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)長(chang)度(du)一般長(chang)25m、克0、6m、高為(wei)2d3(d為(wei)波(bo)紋管(guan)(guan)直徑(jing))，B型(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)一般克為(wei)25m高依據(ju)波(bo)紋管(guan)(guan)直徑(jing)大(da)小(xiao)拼裝接(jie)縫位置確(que)定(ding)尺寸。腳(jiao)(jiao)手(shou)(shou)架(jia)按上述尺寸搭(da)設便于施工、

2、拼裝類型與搭接(jie)方式：拼裝以中心軸(zhou)線(xian)為基準，由中心向兩端對稱進行安裝，直(zhi)至(zhi)兩端。1斷(duan)面(mian)(奇數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶(ou)數斷(duan)面(mian))、加強斷(duan)面(mian)(偶(ou)數斷(duan)管(guan)管(guan)片(pian)）

3、波(bo)紋(wen)管拼裝(zhuang)(zhuang)：采用刻(ke)(ke)槽法施工的(de)地(di)基(ji)，安(an)裝(zhuang)(zhuang)吊車依(yi)據刻(ke)(ke)槽深度(du)，依(yi)次安(an)裝(zhuang)(zhuang)底部管片(pian)。底部管片(pian)安(an)裝(zhuang)(zhuang)完成(cheng)后(hou)對剩余管片(pian)進行安(an)裝(zhuang)(zhuang)。管片(pian)安(an)裝(zhuang)(zhuang)同平基(ji)上(shang)的(de)鋼波(bo)紋(wen)管施工。

首圈(quan)(quan)(quan)(quan)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管圈(quan)(quan)(quan)(quan)為奇(qi)數(shu)斷(duan)面(mian)(mian)，拼裝時應將管片(pian)(pian)(pian)(pian)立(li)于(yu)地(di)上(shang)安(an)裝，使用(yong)(yong)鐵鉤的(de)(de)(de)(de)(de)(de)一端勾(gou)住I斷(duan)面(mian)(mian)片(pian)(pian)(pian)(pian)(1#管片(pian)(pian)(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管管片(pian)(pian)(pian)(pian)螺(luo)(luo)(luo)(luo)絲囗，用(yong)(yong)12噸的(de)(de)(de)(de)(de)(de)吊車(che)勾(gou)住鐵鉤的(de)(de)(de)(de)(de)(de)另一端，將波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管片(pian)(pian)(pian)(pian)立(li)于(yu)墊(dian)層上(shang)，然后(hou)(hou)使用(yong)(yong)同樣的(de)(de)(de)(de)(de)(de)辦法將第二(er)片(pian)(pian)(pian)(pian)(6#管片(pian)(pian)(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管管片(pian)(pian)(pian)(pian)按圖3、21斷(duan)面(mian)(mian)所(suo)示的(de)(de)(de)(de)(de)(de)搭接(jie)方式放置(zhi)，使用(yong)(yong)撬棍將管片(pian)(pian)(pian)(pian)的(de)(de)(de)(de)(de)(de)螺(luo)(luo)(luo)(luo)栓(shuan)(shuan)口對齊，將提(ti)前(qian)準備好的(de)(de)(de)(de)(de)(de)螺(luo)(luo)(luo)(luo)栓(shuan)(shuan)螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)部(bu)(bu)涂(tu)上(shang)渢滑(hua)劑，由內冋外插(cha)入(ru)孔位；波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管外側套上(shang)凹墊(dian)圈(quan)(quan)(quan)(quan)或(huo)凸墊(dian)圈(quan)(quan)(quan)(quan)，遇波(bo)(bo)(bo)使用(yong)(yong)凸墊(dian)圈(quan)(quan)(quan)(quan)，遇波(bo)(bo)(bo)峰(feng)使用(yong)(yong)凹墊(dian)圈(quan)(quan)(quan)(quan)墊(dian)圈(quan)(quan)(quan)(quan)外側旋上(shang)螺(luo)(luo)(luo)(luo)母(mu)，在用(yong)(yong)套筒(tong)扳手(shou)預緊(jin)(jin)(jin)螺(luo)(luo)(luo)(luo)母(mu)，然后(hou)(hou)使用(yong)(yong)電動扳手(shou)緊(jin)(jin)(jin)固螺(luo)(luo)(luo)(luo)母(mu)兩塊板(ban)片(pian)(pian)(pian)(pian)洤全部(bu)(bu)安(an)裝完畢;波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管的(de)(de)(de)(de)(de)(de)螺(luo)(luo)(luo)(luo)栓(shuan)(shuan)安(an)裝完畢后(hou)(hou)，需采(cai)用(yong)(yong)專(zhuan)用(yong)(yong)注(zhu)膠槍于(yu)端部(bu)(bu)接(jie)合處、緊(jin)(jin)(jin)回(hui)件連接(jie)的(de)(de)(de)(de)(de)(de)螺(luo)(luo)(luo)(luo)栓(shuan)(shuan)孔空隙(xi)處涂(tu)抹中性(xing)硅酮耐候(hou)膠。緊(jin)(jin)(jin)接(jie)著按2#管片(pian)(pian)(pian)(pian)、5#管片(pian)(pian)(pian)(pian)、3#管片(pian)(pian)(pian)(pian)、4#管片(pian)(pian)(pian)(pian)的(de)(de)(de)(de)(de)(de)施(shi)工拼裝順序(xu)，拼裝好首圈(quan)(quan)(quan)(quan)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管圖36偶數(shu)、奇(qi)數(shu)斷(duan)面(mian)(mian)交替(ti)拼裝順序(xu)

4、加強斷面拼裝

當波(bo)紋管(guan)涵直(zhi)徑較(jiao)大、填(tian)土高(gao)度較(jiao)高(gao)時，必須設置加(jia)(jia)強管(guan)片，稱為加(jia)(jia)強圈(quan)”，加(jia)(jia)強斷面的管(guan)片安裝工序(xu)。
