大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼裝支架(jia)(jia)(jia):搭(da)(da)設腳手架(jia)(jia)(jia)根據(ju)波紋管(guan)的直(zhi)(zhi)徑(jing)提前確定，采用管(guan)扣(kou)連接鋼管(guan)的方式(shi)搭(da)(da)設腳手架(jia)(jia)(jia)，形式(shi)分A型和B型腳手架(jia)(jia)(jia)長度(du)一般長25m、克(ke)0、6m、高(gao)為2d3(d為波紋管(guan)直(zhi)(zhi)徑(jing))，B型腳手架(jia)(jia)(jia)一般克(ke)為25m高(gao)依(yi)據(ju)波紋管(guan)直(zhi)(zhi)徑(jing)大(da)小拼裝接縫位置(zhi)確定尺(chi)寸。腳手架(jia)(jia)(jia)按上述尺(chi)寸搭(da)(da)設便于施工、

2、拼裝類型與搭接(jie)方式：拼裝以中心軸線為基準，由(you)中心向(xiang)兩(liang)(liang)端對稱進行安(an)裝，直(zhi)至兩(liang)(liang)端。1斷(duan)面(mian)(mian)(奇數(shu)斷(duan)面(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(偶數(shu)斷(duan)面(mian)(mian))、加強(qiang)斷(duan)面(mian)(mian)(偶數(shu)斷(duan)管(guan)管(guan)片）

3、波紋管(guan)(guan)拼(pin)裝：采用刻(ke)槽法(fa)施(shi)工(gong)的地(di)基，安(an)裝吊車依據刻(ke)槽深度(du)，依次安(an)裝底部管(guan)(guan)片(pian)。底部管(guan)(guan)片(pian)安(an)裝完成后(hou)對剩(sheng)余管(guan)(guan)片(pian)進行安(an)裝。管(guan)(guan)片(pian)安(an)裝同平基上的鋼波紋管(guan)(guan)施(shi)工(gong)。

首圈(quan)波(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)圈(quan)為奇(qi)數斷(duan)面，拼(pin)(pin)裝時(shi)應(ying)將(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于地上(shang)(shang)安(an)裝，使(shi)用(yong)(yong)(yong)(yong)鐵鉤的(de)一端勾住I斷(duan)面片(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)(yong)(yong)12噸的(de)吊(diao)車勾住鐵鉤的(de)另(ling)一端，將(jiang)(jiang)波(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于墊(dian)層上(shang)(shang)，然后使(shi)用(yong)(yong)(yong)(yong)同(tong)樣的(de)辦法將(jiang)(jiang)第二(er)片(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)按圖(tu)3、21斷(duan)面所示(shi)的(de)搭接方式(shi)放置(zhi)，使(shi)用(yong)(yong)(yong)(yong)撬棍將(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)螺(luo)(luo)栓口(kou)對齊，將(jiang)(jiang)提前準備好(hao)的(de)螺(luo)(luo)栓螺(luo)(luo)紋部涂(tu)上(shang)(shang)渢滑劑，由內冋(jiong)外(wai)插入(ru)孔位；波(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)外(wai)側(ce)套上(shang)(shang)凹墊(dian)圈(quan)或凸(tu)墊(dian)圈(quan)，遇波(bo)使(shi)用(yong)(yong)(yong)(yong)凸(tu)墊(dian)圈(quan)，遇波(bo)峰(feng)使(shi)用(yong)(yong)(yong)(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外(wai)側(ce)旋上(shang)(shang)螺(luo)(luo)母，在(zai)用(yong)(yong)(yong)(yong)套筒扳(ban)手預(yu)緊螺(luo)(luo)母，然后使(shi)用(yong)(yong)(yong)(yong)電動扳(ban)手緊固螺(luo)(luo)母兩塊(kuai)板片(pian)(pian)(pian)(pian)洤全部安(an)裝完(wan)畢;波(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)的(de)螺(luo)(luo)栓安(an)裝完(wan)畢后，需采(cai)用(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)注膠槍于端部接合(he)處(chu)、緊回(hui)件(jian)連接的(de)螺(luo)(luo)栓孔空隙處(chu)涂(tu)抹中性硅酮耐候(hou)膠。緊接著(zhu)按2#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)施工拼(pin)(pin)裝順(shun)序，拼(pin)(pin)裝好(hao)首圈(quan)波(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)圖(tu)36偶(ou)數、奇(qi)數斷(duan)面交替拼(pin)(pin)裝順(shun)序

4、加強斷面拼裝

當波紋管(guan)涵(han)直(zhi)徑較(jiao)(jiao)大、填(tian)土(tu)高(gao)度較(jiao)(jiao)高(gao)時，必須(xu)設置加(jia)(jia)強(qiang)(qiang)管(guan)片，稱為加(jia)(jia)強(qiang)(qiang)圈”，加(jia)(jia)強(qiang)(qiang)斷面的(de)管(guan)片安裝工序(xu)。
