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)設腳手(shou)架(jia)根(gen)據波(bo)紋管(guan)的直徑提前確(que)定，采用管(guan)扣連(lian)接鋼管(guan)的方式搭(da)設腳手(shou)架(jia)，形(xing)式分A型和B型腳手(shou)架(jia)長度(du)一般長25m、克(ke)0、6m、高為(wei)2d3(d為(wei)波(bo)紋管(guan)直徑)，B型腳手(shou)架(jia)一般克(ke)為(wei)25m高依(yi)據波(bo)紋管(guan)直徑大小拼裝接縫位(wei)置確(que)定尺(chi)寸(cun)。腳手(shou)架(jia)按上述尺(chi)寸(cun)搭(da)設便于施工、

2、拼裝類型與(yu)搭接(jie)方式：拼裝以中(zhong)(zhong)心軸線(xian)為(wei)基準，由中(zhong)(zhong)心向兩(liang)端對稱進(jin)行(xing)安裝，直至兩(liang)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、波紋管(guan)拼裝：采用刻槽法(fa)施工的(de)地基(ji)，安(an)裝吊車依據刻槽深度，依次安(an)裝底部(bu)管(guan)片(pian)。底部(bu)管(guan)片(pian)安(an)裝完成后對剩(sheng)余管(guan)片(pian)進(jin)行安(an)裝。管(guan)片(pian)安(an)裝同平基(ji)上的(de)鋼波紋管(guan)施工。

鋼波紋管

首圈波紋(wen)(wen)管(guan)(guan)(guan)圈為奇數(shu)斷(duan)面(mian)(mian)，拼(pin)裝(zhuang)時應將(jiang)管(guan)(guan)(guan)片(pian)(pian)立于地(di)上安(an)裝(zhuang)，使(shi)用(yong)(yong)鐵鉤的(de)(de)一(yi)端(duan)(duan)勾住I斷(duan)面(mian)(mian)片(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian))波紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)絲(si)囗，用(yong)(yong)12噸的(de)(de)吊車勾住鐵鉤的(de)(de)另一(yi)端(duan)(duan)，將(jiang)波紋(wen)(wen)管(guan)(guan)(guan)片(pian)(pian)立于墊(dian)層上，然(ran)后(hou)使(shi)用(yong)(yong)同樣的(de)(de)辦(ban)法(fa)將(jiang)第(di)二片(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian))波紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)按圖(tu)(tu)3、21斷(duan)面(mian)(mian)所示的(de)(de)搭接方(fang)式放置，使(shi)用(yong)(yong)撬棍將(jiang)管(guan)(guan)(guan)片(pian)(pian)的(de)(de)螺(luo)(luo)栓口對齊，將(jiang)提前準備好的(de)(de)螺(luo)(luo)栓螺(luo)(luo)紋(wen)(wen)部(bu)涂(tu)上渢滑劑，由內冋外插(cha)入孔位；波紋(wen)(wen)管(guan)(guan)(guan)外側(ce)套上凹墊(dian)圈或凸(tu)墊(dian)圈，遇波使(shi)用(yong)(yong)凸(tu)墊(dian)圈，遇波峰(feng)使(shi)用(yong)(yong)凹墊(dian)圈墊(dian)圈外側(ce)旋(xuan)上螺(luo)(luo)母，在用(yong)(yong)套筒扳手預緊螺(luo)(luo)母，然(ran)后(hou)使(shi)用(yong)(yong)電動(dong)扳手緊固(gu)螺(luo)(luo)母兩塊板(ban)片(pian)(pian)洤全部(bu)安(an)裝(zhuang)完(wan)畢;波紋(wen)(wen)管(guan)(guan)(guan)的(de)(de)螺(luo)(luo)栓安(an)裝(zhuang)完(wan)畢后(hou)，需采用(yong)(yong)專用(yong)(yong)注膠(jiao)槍于端(duan)(duan)部(bu)接合(he)處、緊回件連接的(de)(de)螺(luo)(luo)栓孔空隙處涂(tu)抹中性(xing)硅酮耐候膠(jiao)。緊接著按2#管(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)的(de)(de)施工拼(pin)裝(zhuang)順序，拼(pin)裝(zhuang)好首圈波紋(wen)(wen)管(guan)(guan)(guan)圖(tu)(tu)36偶(ou)數(shu)、奇數(shu)斷(duan)面(mian)(mian)交替拼(pin)裝(zhuang)順序

4、加強斷面拼裝

當波紋管(guan)涵直(zhi)徑較大、填土高度(du)較高時，必須設置加(jia)強管(guan)片，稱為加(jia)強圈”，加(jia)強斷面的管(guan)片安裝(zhuang)工序。
