大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)(she)拼(pin)裝(zhuang)支(zhi)架(jia):搭(da)(da)設(she)(she)腳(jiao)手(shou)(shou)架(jia)根(gen)據波(bo)(bo)紋(wen)管(guan)(guan)(guan)的直徑提前確(que)定，采用管(guan)(guan)(guan)扣連接鋼管(guan)(guan)(guan)的方式搭(da)(da)設(she)(she)腳(jiao)手(shou)(shou)架(jia)，形(xing)式分A型(xing)和B型(xing)腳(jiao)手(shou)(shou)架(jia)長(chang)度一般(ban)長(chang)25m、克(ke)0、6m、高為2d3(d為波(bo)(bo)紋(wen)管(guan)(guan)(guan)直徑)，B型(xing)腳(jiao)手(shou)(shou)架(jia)一般(ban)克(ke)為25m高依據波(bo)(bo)紋(wen)管(guan)(guan)(guan)直徑大小(xiao)拼(pin)裝(zhuang)接縫(feng)位置(zhi)確(que)定尺(chi)寸(cun)。腳(jiao)手(shou)(shou)架(jia)按上(shang)述(shu)尺(chi)寸(cun)搭(da)(da)設(she)(she)便于施工、

2、拼(pin)裝(zhuang)(zhuang)類(lei)型與(yu)搭接(jie)方式：拼(pin)裝(zhuang)(zhuang)以中心(xin)軸線(xian)為基準，由中心(xin)向兩端對稱進行安裝(zhuang)(zhuang)，直至兩端。1斷面(mian)(mian)(奇數(shu)斷面(mian)(mian))、Ⅱ斷面(mian)(mian)(偶(ou)數(shu)斷面(mian)(mian))、加(jia)強斷面(mian)(mian)(偶(ou)數(shu)斷管(guan)(guan)管(guan)(guan)片）

3、波紋管(guan)拼裝：采用(yong)刻(ke)槽法施工的地基，安裝吊車依據(ju)刻(ke)槽深度，依次安裝底(di)部管(guan)片。底(di)部管(guan)片安裝完(wan)成后對剩(sheng)余管(guan)片進行安裝。管(guan)片安裝同平基上(shang)的鋼波紋管(guan)施工。

鋼波紋管

首圈(quan)波紋(wen)管圈(quan)為奇數斷(duan)面，拼(pin)(pin)裝(zhuang)(zhuang)(zhuang)時應將(jiang)管片(pian)(pian)(pian)(pian)(pian)立于地上(shang)安(an)裝(zhuang)(zhuang)(zhuang)，使(shi)用(yong)(yong)(yong)(yong)(yong)鐵鉤的(de)一(yi)端(duan)勾住I斷(duan)面片(pian)(pian)(pian)(pian)(pian)(1#管片(pian)(pian)(pian)(pian)(pian))波紋(wen)管管片(pian)(pian)(pian)(pian)(pian)螺(luo)(luo)(luo)(luo)絲囗(wei)，用(yong)(yong)(yong)(yong)(yong)12噸的(de)吊車勾住鐵鉤的(de)另一(yi)端(duan)，將(jiang)波紋(wen)管片(pian)(pian)(pian)(pian)(pian)立于墊(dian)(dian)(dian)層上(shang)，然后(hou)(hou)使(shi)用(yong)(yong)(yong)(yong)(yong)同樣的(de)辦法將(jiang)第二(er)片(pian)(pian)(pian)(pian)(pian)(6#管片(pian)(pian)(pian)(pian)(pian))波紋(wen)管管片(pian)(pian)(pian)(pian)(pian)按圖3、21斷(duan)面所示的(de)搭接方(fang)式放置，使(shi)用(yong)(yong)(yong)(yong)(yong)撬棍將(jiang)管片(pian)(pian)(pian)(pian)(pian)的(de)螺(luo)(luo)(luo)(luo)栓(shuan)口對齊，將(jiang)提前準(zhun)備好的(de)螺(luo)(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)(luo)紋(wen)部涂(tu)上(shang)渢(feng)滑劑，由內冋外插入(ru)孔位；波紋(wen)管外側(ce)(ce)套上(shang)凹墊(dian)(dian)(dian)圈(quan)或凸墊(dian)(dian)(dian)圈(quan)，遇(yu)波使(shi)用(yong)(yong)(yong)(yong)(yong)凸墊(dian)(dian)(dian)圈(quan)，遇(yu)波峰使(shi)用(yong)(yong)(yong)(yong)(yong)凹墊(dian)(dian)(dian)圈(quan)墊(dian)(dian)(dian)圈(quan)外側(ce)(ce)旋上(shang)螺(luo)(luo)(luo)(luo)母，在用(yong)(yong)(yong)(yong)(yong)套筒(tong)扳(ban)手預(yu)緊螺(luo)(luo)(luo)(luo)母，然后(hou)(hou)使(shi)用(yong)(yong)(yong)(yong)(yong)電動扳(ban)手緊固(gu)螺(luo)(luo)(luo)(luo)母兩塊板(ban)片(pian)(pian)(pian)(pian)(pian)洤全部安(an)裝(zhuang)(zhuang)(zhuang)完畢;波紋(wen)管的(de)螺(luo)(luo)(luo)(luo)栓(shuan)安(an)裝(zhuang)(zhuang)(zhuang)完畢后(hou)(hou)，需(xu)采用(yong)(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)(yong)注膠(jiao)槍于端(duan)部接合處、緊回件連接的(de)螺(luo)(luo)(luo)(luo)栓(shuan)孔空隙處涂(tu)抹(mo)中性硅酮耐候膠(jiao)。緊接著按2#管片(pian)(pian)(pian)(pian)(pian)、5#管片(pian)(pian)(pian)(pian)(pian)、3#管片(pian)(pian)(pian)(pian)(pian)、4#管片(pian)(pian)(pian)(pian)(pian)的(de)施(shi)工拼(pin)(pin)裝(zhuang)(zhuang)(zhuang)順(shun)(shun)序，拼(pin)(pin)裝(zhuang)(zhuang)(zhuang)好首圈(quan)波紋(wen)管圖36偶數、奇數斷(duan)面交(jiao)替拼(pin)(pin)裝(zhuang)(zhuang)(zhuang)順(shun)(shun)序

4、加強斷面拼裝

當波紋(wen)管(guan)涵直徑較大、填土(tu)高度較高時，必須(xu)設置加(jia)(jia)強(qiang)管(guan)片，稱為加(jia)(jia)強(qiang)圈”，加(jia)(jia)強(qiang)斷面的管(guan)片安裝(zhuang)工(gong)序。
