大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼(pin)裝(zhuang)(zhuang)支架(jia):搭(da)設腳(jiao)手架(jia)根據(ju)(ju)波(bo)紋(wen)(wen)管(guan)(guan)的直(zhi)徑提前(qian)確定(ding)，采用管(guan)(guan)扣連(lian)接鋼管(guan)(guan)的方(fang)式搭(da)設腳(jiao)手架(jia)，形式分A型和(he)B型腳(jiao)手架(jia)長度(du)一(yi)般長25m、克0、6m、高為(wei)2d3(d為(wei)波(bo)紋(wen)(wen)管(guan)(guan)直(zhi)徑)，B型腳(jiao)手架(jia)一(yi)般克為(wei)25m高依據(ju)(ju)波(bo)紋(wen)(wen)管(guan)(guan)直(zhi)徑大小拼(pin)裝(zhuang)(zhuang)接縫位置確定(ding)尺寸。腳(jiao)手架(jia)按(an)上述尺寸搭(da)設便于(yu)施工、

2、拼(pin)(pin)裝類型(xing)與搭接方式：拼(pin)(pin)裝以中(zhong)心(xin)軸線為基準，由(you)中(zhong)心(xin)向兩端對(dui)稱進行(xing)安裝，直至兩端。1斷(duan)(duan)面(mian)(mian)(奇數斷(duan)(duan)面(mian)(mian))、Ⅱ斷(duan)(duan)面(mian)(mian)(偶(ou)數斷(duan)(duan)面(mian)(mian))、加強斷(duan)(duan)面(mian)(mian)(偶(ou)數斷(duan)(duan)管管片）

3、波紋(wen)管(guan)(guan)(guan)拼裝(zhuang)(zhuang)：采用刻(ke)槽法(fa)施工的地基，安裝(zhuang)(zhuang)吊車依(yi)據刻(ke)槽深度(du)，依(yi)次安裝(zhuang)(zhuang)底(di)部管(guan)(guan)(guan)片(pian)(pian)。底(di)部管(guan)(guan)(guan)片(pian)(pian)安裝(zhuang)(zhuang)完成后對(dui)剩余管(guan)(guan)(guan)片(pian)(pian)進行安裝(zhuang)(zhuang)。管(guan)(guan)(guan)片(pian)(pian)安裝(zhuang)(zhuang)同(tong)平(ping)基上的鋼波紋(wen)管(guan)(guan)(guan)施工。

首圈(quan)(quan)(quan)波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)圈(quan)(quan)(quan)為奇數(shu)斷(duan)面，拼(pin)(pin)裝時應將(jiang)(jiang)管(guan)(guan)(guan)片(pian)(pian)立于地上安裝，使(shi)(shi)用(yong)鐵鉤的(de)(de)(de)(de)一端勾住(zhu)I斷(duan)面片(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)螺(luo)絲囗(wei)，用(yong)12噸的(de)(de)(de)(de)吊(diao)車勾住(zhu)鐵鉤的(de)(de)(de)(de)另一端，將(jiang)(jiang)波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)片(pian)(pian)立于墊(dian)層上，然(ran)后使(shi)(shi)用(yong)同樣的(de)(de)(de)(de)辦(ban)法將(jiang)(jiang)第二片(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)按圖3、21斷(duan)面所示(shi)的(de)(de)(de)(de)搭接方(fang)式放置，使(shi)(shi)用(yong)撬棍將(jiang)(jiang)管(guan)(guan)(guan)片(pian)(pian)的(de)(de)(de)(de)螺(luo)栓口(kou)對齊(qi)，將(jiang)(jiang)提前準備好的(de)(de)(de)(de)螺(luo)栓螺(luo)紋(wen)部(bu)涂上渢滑劑，由內冋外(wai)插入(ru)孔位；波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)外(wai)側套上凹(ao)(ao)墊(dian)圈(quan)(quan)(quan)或凸墊(dian)圈(quan)(quan)(quan)，遇(yu)波(bo)(bo)(bo)使(shi)(shi)用(yong)凸墊(dian)圈(quan)(quan)(quan)，遇(yu)波(bo)(bo)(bo)峰使(shi)(shi)用(yong)凹(ao)(ao)墊(dian)圈(quan)(quan)(quan)墊(dian)圈(quan)(quan)(quan)外(wai)側旋(xuan)上螺(luo)母，在用(yong)套筒扳手預緊螺(luo)母，然(ran)后使(shi)(shi)用(yong)電動扳手緊固螺(luo)母兩塊板片(pian)(pian)洤全部(bu)安裝完(wan)畢(bi);波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)的(de)(de)(de)(de)螺(luo)栓安裝完(wan)畢(bi)后，需采用(yong)專用(yong)注膠槍(qiang)于端部(bu)接合處、緊回件連接的(de)(de)(de)(de)螺(luo)栓孔空隙處涂抹中性硅酮耐(nai)候膠。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)(de)(de)施工拼(pin)(pin)裝順序，拼(pin)(pin)裝好首圈(quan)(quan)(quan)波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)圖36偶(ou)數(shu)、奇數(shu)斷(duan)面交替(ti)拼(pin)(pin)裝順序

4、加強斷面拼裝

當波(bo)紋管涵直徑較(jiao)大、填(tian)土高度較(jiao)高時，必須設置加(jia)(jia)強管片(pian)，稱(cheng)為加(jia)(jia)強圈”，加(jia)(jia)強斷面的(de)管片(pian)安裝工(gong)序(xu)。
