大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝(zhuang)支架(jia)(jia)(jia):搭設腳(jiao)手(shou)架(jia)(jia)(jia)根(gen)據波(bo)(bo)紋(wen)(wen)管(guan)的(de)直(zhi)徑提前確定，采(cai)用管(guan)扣連接(jie)鋼管(guan)的(de)方式搭設腳(jiao)手(shou)架(jia)(jia)(jia)，形式分A型(xing)(xing)和B型(xing)(xing)腳(jiao)手(shou)架(jia)(jia)(jia)長(chang)度一般(ban)(ban)長(chang)25m、克0、6m、高(gao)為2d3(d為波(bo)(bo)紋(wen)(wen)管(guan)直(zhi)徑)，B型(xing)(xing)腳(jiao)手(shou)架(jia)(jia)(jia)一般(ban)(ban)克為25m高(gao)依據波(bo)(bo)紋(wen)(wen)管(guan)直(zhi)徑大小(xiao)拼(pin)裝(zhuang)接(jie)縫(feng)位置確定尺(chi)寸。腳(jiao)手(shou)架(jia)(jia)(jia)按上述尺(chi)寸搭設便于施(shi)工、

2、拼裝類型與搭接方式(shi)：拼裝以中(zhong)(zhong)心軸線為基準(zhun)，由中(zhong)(zhong)心向(xiang)兩端對稱(cheng)進(jin)行安裝，直至兩端。1斷(duan)面(奇數斷(duan)面)、Ⅱ斷(duan)面(偶數斷(duan)面)、加(jia)強斷(duan)面(偶數斷(duan)管管片）

3、波紋管拼裝(zhuang)：采用刻(ke)槽法施(shi)工的地(di)基，安裝(zhuang)吊車依據刻(ke)槽深度，依次安裝(zhuang)底部管片。底部管片安裝(zhuang)完成(cheng)后對剩余管片進行安裝(zhuang)。管片安裝(zhuang)同平基上的鋼波紋管施(shi)工。

鋼波紋管

首圈(quan)(quan)(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)圈(quan)(quan)(quan)為奇數(shu)(shu)斷面(mian)(mian)，拼裝時應將(jiang)管(guan)(guan)片(pian)(pian)立于地上(shang)安(an)裝，使(shi)(shi)(shi)用(yong)鐵(tie)鉤的(de)一端勾住I斷面(mian)(mian)片(pian)(pian)(1#管(guan)(guan)片(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)螺(luo)絲囗，用(yong)12噸的(de)吊車(che)勾住鐵(tie)鉤的(de)另(ling)一端，將(jiang)波(bo)紋(wen)(wen)(wen)管(guan)(guan)片(pian)(pian)立于墊(dian)層上(shang)，然后(hou)使(shi)(shi)(shi)用(yong)同樣(yang)的(de)辦法將(jiang)第(di)二片(pian)(pian)(6#管(guan)(guan)片(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)按(an)圖(tu)3、21斷面(mian)(mian)所示(shi)的(de)搭接(jie)(jie)方式放置(zhi)，使(shi)(shi)(shi)用(yong)撬(qiao)棍將(jiang)管(guan)(guan)片(pian)(pian)的(de)螺(luo)栓(shuan)口對(dui)齊，將(jiang)提前準(zhun)備(bei)好(hao)的(de)螺(luo)栓(shuan)螺(luo)紋(wen)(wen)(wen)部(bu)涂上(shang)渢滑劑，由(you)內冋外插入(ru)孔位；波(bo)紋(wen)(wen)(wen)管(guan)(guan)外側套上(shang)凹(ao)墊(dian)圈(quan)(quan)(quan)或凸墊(dian)圈(quan)(quan)(quan)，遇(yu)波(bo)使(shi)(shi)(shi)用(yong)凸墊(dian)圈(quan)(quan)(quan)，遇(yu)波(bo)峰使(shi)(shi)(shi)用(yong)凹(ao)墊(dian)圈(quan)(quan)(quan)墊(dian)圈(quan)(quan)(quan)外側旋上(shang)螺(luo)母，在(zai)用(yong)套筒扳手預緊(jin)(jin)螺(luo)母，然后(hou)使(shi)(shi)(shi)用(yong)電動扳手緊(jin)(jin)固螺(luo)母兩塊板(ban)片(pian)(pian)洤全部(bu)安(an)裝完畢(bi)(bi);波(bo)紋(wen)(wen)(wen)管(guan)(guan)的(de)螺(luo)栓(shuan)安(an)裝完畢(bi)(bi)后(hou)，需采用(yong)專用(yong)注膠槍于端部(bu)接(jie)(jie)合處、緊(jin)(jin)回件連接(jie)(jie)的(de)螺(luo)栓(shuan)孔空(kong)隙(xi)處涂抹中性硅酮耐候膠。緊(jin)(jin)接(jie)(jie)著按(an)2#管(guan)(guan)片(pian)(pian)、5#管(guan)(guan)片(pian)(pian)、3#管(guan)(guan)片(pian)(pian)、4#管(guan)(guan)片(pian)(pian)的(de)施工拼裝順序，拼裝好(hao)首圈(quan)(quan)(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)圖(tu)36偶數(shu)(shu)、奇數(shu)(shu)斷面(mian)(mian)交替拼裝順序

4、加強斷面拼裝

當波紋管涵直徑較大、填土高(gao)度較高(gao)時，必須設置(zhi)加強(qiang)(qiang)管片(pian)，稱為加強(qiang)(qiang)圈”，加強(qiang)(qiang)斷面的管片(pian)安裝工(gong)序。
