大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)(she)拼(pin)裝支架(jia):搭(da)設(she)(she)腳手(shou)(shou)(shou)架(jia)根據波紋管的直徑提前確定(ding)，采用管扣(kou)連接(jie)鋼管的方式搭(da)設(she)(she)腳手(shou)(shou)(shou)架(jia)，形式分(fen)A型和(he)B型腳手(shou)(shou)(shou)架(jia)長度一般長25m、克0、6m、高為2d3(d為波紋管直徑)，B型腳手(shou)(shou)(shou)架(jia)一般克為25m高依(yi)據波紋管直徑大(da)小(xiao)拼(pin)裝接(jie)縫位置確定(ding)尺(chi)寸。腳手(shou)(shou)(shou)架(jia)按上述(shu)尺(chi)寸搭(da)設(she)(she)便于施工、

2、拼裝(zhuang)類(lei)型與搭接方式：拼裝(zhuang)以中(zhong)心軸線為基準，由(you)中(zhong)心向(xiang)兩端對(dui)稱進行安裝(zhuang)，直至(zhi)兩端。1斷(duan)(duan)面(mian)(mian)(mian)(奇數(shu)斷(duan)(duan)面(mian)(mian)(mian))、Ⅱ斷(duan)(duan)面(mian)(mian)(mian)(偶(ou)(ou)數(shu)斷(duan)(duan)面(mian)(mian)(mian))、加強斷(duan)(duan)面(mian)(mian)(mian)(偶(ou)(ou)數(shu)斷(duan)(duan)管管片）

3、波(bo)紋管(guan)(guan)拼裝(zhuang)：采用(yong)刻(ke)槽(cao)法施工(gong)的地基，安(an)裝(zhuang)吊(diao)車依(yi)據(ju)刻(ke)槽(cao)深度，依(yi)次(ci)安(an)裝(zhuang)底(di)部管(guan)(guan)片。底(di)部管(guan)(guan)片安(an)裝(zhuang)完成后對剩余管(guan)(guan)片進(jin)行安(an)裝(zhuang)。管(guan)(guan)片安(an)裝(zhuang)同平基上的鋼波(bo)紋管(guan)(guan)施工(gong)。

首圈波(bo)(bo)紋管(guan)(guan)圈為(wei)奇數(shu)斷面，拼(pin)裝(zhuang)(zhuang)(zhuang)(zhuang)時應將管(guan)(guan)片(pian)(pian)(pian)(pian)立于地上安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)，使(shi)用(yong)(yong)鐵鉤的(de)(de)(de)一端(duan)(duan)勾住(zhu)I斷面片(pian)(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)絲囗，用(yong)(yong)12噸(dun)的(de)(de)(de)吊車勾住(zhu)鐵鉤的(de)(de)(de)另一端(duan)(duan)，將波(bo)(bo)紋管(guan)(guan)片(pian)(pian)(pian)(pian)立于墊(dian)層上，然后使(shi)用(yong)(yong)同(tong)樣的(de)(de)(de)辦法將第二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)按圖3、21斷面所示的(de)(de)(de)搭(da)接方(fang)式放置，使(shi)用(yong)(yong)撬棍將管(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)螺(luo)栓(shuan)口對齊，將提(ti)前準備(bei)好的(de)(de)(de)螺(luo)栓(shuan)螺(luo)紋部涂(tu)上渢滑劑(ji)，由內冋(jiong)外插入孔位；波(bo)(bo)紋管(guan)(guan)外側套上凹(ao)墊(dian)圈或(huo)凸(tu)(tu)墊(dian)圈，遇(yu)波(bo)(bo)使(shi)用(yong)(yong)凸(tu)(tu)墊(dian)圈，遇(yu)波(bo)(bo)峰(feng)使(shi)用(yong)(yong)凹(ao)墊(dian)圈墊(dian)圈外側旋上螺(luo)母，在用(yong)(yong)套筒扳(ban)手預(yu)緊(jin)(jin)(jin)螺(luo)母，然后使(shi)用(yong)(yong)電(dian)動扳(ban)手緊(jin)(jin)(jin)固螺(luo)母兩(liang)塊(kuai)板片(pian)(pian)(pian)(pian)洤全部安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)完(wan)畢(bi);波(bo)(bo)紋管(guan)(guan)的(de)(de)(de)螺(luo)栓(shuan)安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)完(wan)畢(bi)后，需采用(yong)(yong)專(zhuan)用(yong)(yong)注(zhu)膠(jiao)槍于端(duan)(duan)部接合處、緊(jin)(jin)(jin)回件連接的(de)(de)(de)螺(luo)栓(shuan)孔空(kong)隙處涂(tu)抹中性硅酮耐候膠(jiao)。緊(jin)(jin)(jin)接著按2#管(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)施工拼(pin)裝(zhuang)(zhuang)(zhuang)(zhuang)順序，拼(pin)裝(zhuang)(zhuang)(zhuang)(zhuang)好首圈波(bo)(bo)紋管(guan)(guan)圖36偶(ou)數(shu)、奇數(shu)斷面交替拼(pin)裝(zhuang)(zhuang)(zhuang)(zhuang)順序

4、加強斷面拼裝

當波紋管涵直徑較大(da)、填土高度較高時，必須(xu)設置加強管片(pian)，稱為加強圈(quan)”，加強斷面的管片(pian)安裝工序。
