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):搭設腳(jiao)(jiao)手(shou)(shou)架(jia)根據波紋(wen)管的直徑(jing)提前確定，采(cai)用管扣連接鋼管的方式(shi)(shi)搭設腳(jiao)(jiao)手(shou)(shou)架(jia)，形式(shi)(shi)分A型(xing)和B型(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)長度一(yi)般(ban)長25m、克(ke)0、6m、高為2d3(d為波紋(wen)管直徑(jing))，B型(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)一(yi)般(ban)克(ke)為25m高依據波紋(wen)管直徑(jing)大(da)小拼(pin)裝(zhuang)接縫位(wei)置確定尺寸。腳(jiao)(jiao)手(shou)(shou)架(jia)按上述(shu)尺寸搭設便(bian)于施工(gong)、

2、拼(pin)裝(zhuang)類型(xing)與搭接方式：拼(pin)裝(zhuang)以中(zhong)心軸線為基準，由中(zhong)心向(xiang)兩端對稱進(jin)行安裝(zhuang)，直至兩端。1斷(duan)面(mian)(奇數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數斷(duan)面(mian))、加強斷(duan)面(mian)(偶數斷(duan)管管片）

3、波紋(wen)管拼(pin)裝(zhuang)(zhuang)(zhuang)：采(cai)用刻槽法施工的地基(ji)，安(an)(an)裝(zhuang)(zhuang)(zhuang)吊車依(yi)據(ju)刻槽深度，依(yi)次安(an)(an)裝(zhuang)(zhuang)(zhuang)底部管片(pian)。底部管片(pian)安(an)(an)裝(zhuang)(zhuang)(zhuang)完(wan)成后對(dui)剩余管片(pian)進行(xing)安(an)(an)裝(zhuang)(zhuang)(zhuang)。管片(pian)安(an)(an)裝(zhuang)(zhuang)(zhuang)同(tong)平基(ji)上的鋼波紋(wen)管施工。

首(shou)(shou)圈(quan)(quan)(quan)波(bo)紋(wen)管(guan)(guan)(guan)圈(quan)(quan)(quan)為奇數(shu)(shu)斷面(mian)，拼(pin)裝時應將(jiang)(jiang)(jiang)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于地上(shang)安(an)裝，使(shi)(shi)用(yong)鐵鉤(gou)的(de)(de)一(yi)端勾住I斷面(mian)片(pian)(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)螺(luo)絲(si)囗，用(yong)12噸的(de)(de)吊車勾住鐵鉤(gou)的(de)(de)另一(yi)端，將(jiang)(jiang)(jiang)波(bo)紋(wen)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于墊(dian)(dian)層上(shang)，然后(hou)使(shi)(shi)用(yong)同樣的(de)(de)辦法將(jiang)(jiang)(jiang)第二片(pian)(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)按圖3、21斷面(mian)所示的(de)(de)搭接(jie)方式放置，使(shi)(shi)用(yong)撬棍(gun)將(jiang)(jiang)(jiang)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)螺(luo)栓(shuan)口(kou)對齊，將(jiang)(jiang)(jiang)提(ti)前準備(bei)好的(de)(de)螺(luo)栓(shuan)螺(luo)紋(wen)部涂上(shang)渢滑劑，由內冋外(wai)插入孔位；波(bo)紋(wen)管(guan)(guan)(guan)外(wai)側套上(shang)凹(ao)墊(dian)(dian)圈(quan)(quan)(quan)或凸(tu)(tu)墊(dian)(dian)圈(quan)(quan)(quan)，遇波(bo)使(shi)(shi)用(yong)凸(tu)(tu)墊(dian)(dian)圈(quan)(quan)(quan)，遇波(bo)峰(feng)使(shi)(shi)用(yong)凹(ao)墊(dian)(dian)圈(quan)(quan)(quan)墊(dian)(dian)圈(quan)(quan)(quan)外(wai)側旋上(shang)螺(luo)母，在用(yong)套筒扳手(shou)預緊螺(luo)母，然后(hou)使(shi)(shi)用(yong)電動扳手(shou)緊固螺(luo)母兩(liang)塊板片(pian)(pian)(pian)(pian)(pian)洤全部安(an)裝完畢(bi);波(bo)紋(wen)管(guan)(guan)(guan)的(de)(de)螺(luo)栓(shuan)安(an)裝完畢(bi)后(hou)，需采用(yong)專用(yong)注膠(jiao)槍于端部接(jie)合處、緊回(hui)件連(lian)接(jie)的(de)(de)螺(luo)栓(shuan)孔空隙(xi)處涂抹(mo)中性硅酮耐候膠(jiao)。緊接(jie)著按2#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)施工(gong)拼(pin)裝順序(xu)，拼(pin)裝好首(shou)(shou)圈(quan)(quan)(quan)波(bo)紋(wen)管(guan)(guan)(guan)圖36偶數(shu)(shu)、奇數(shu)(shu)斷面(mian)交替拼(pin)裝順序(xu)

4、加強斷面拼裝

當波紋(wen)管(guan)(guan)涵直徑較大、填土(tu)高度較高時，必(bi)須設置加(jia)強管(guan)(guan)片(pian)，稱為加(jia)強圈”，加(jia)強斷面的管(guan)(guan)片(pian)安裝工序。
