大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼裝支架(jia):搭(da)(da)設腳(jiao)(jiao)(jiao)手(shou)架(jia)根(gen)據波(bo)紋管(guan)的直(zhi)徑提前確(que)定，采用管(guan)扣連接鋼(gang)管(guan)的方式搭(da)(da)設腳(jiao)(jiao)(jiao)手(shou)架(jia)，形(xing)式分A型和(he)B型腳(jiao)(jiao)(jiao)手(shou)架(jia)長度一般長25m、克0、6m、高為2d3(d為波(bo)紋管(guan)直(zhi)徑)，B型腳(jiao)(jiao)(jiao)手(shou)架(jia)一般克為25m高依據波(bo)紋管(guan)直(zhi)徑大小拼裝接縫(feng)位置確(que)定尺寸。腳(jiao)(jiao)(jiao)手(shou)架(jia)按上述尺寸搭(da)(da)設便于(yu)施(shi)工、

2、拼(pin)裝類(lei)型(xing)與搭接(jie)方(fang)式(shi)：拼(pin)裝以中(zhong)心軸線(xian)為基準，由中(zhong)心向兩端(duan)對稱進(jin)行安裝，直至兩端(duan)。1斷(duan)(duan)面(奇數斷(duan)(duan)面)、Ⅱ斷(duan)(duan)面(偶數斷(duan)(duan)面)、加強(qiang)斷(duan)(duan)面(偶數斷(duan)(duan)管管片）

3、波紋管(guan)(guan)拼(pin)裝(zhuang)：采用刻槽法施(shi)工的(de)地基，安(an)裝(zhuang)吊車依(yi)據(ju)刻槽深度，依(yi)次安(an)裝(zhuang)底(di)部管(guan)(guan)片(pian)(pian)。底(di)部管(guan)(guan)片(pian)(pian)安(an)裝(zhuang)完成后對剩余管(guan)(guan)片(pian)(pian)進行安(an)裝(zhuang)。管(guan)(guan)片(pian)(pian)安(an)裝(zhuang)同平(ping)基上的(de)鋼波紋管(guan)(guan)施(shi)工。

鋼波紋管

首(shou)圈波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圈為奇數(shu)斷(duan)面，拼(pin)裝(zhuang)(zhuang)(zhuang)時應將管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)地上安(an)裝(zhuang)(zhuang)(zhuang)，使(shi)(shi)(shi)用(yong)(yong)鐵鉤的(de)(de)(de)一(yi)端(duan)勾(gou)(gou)住I斷(duan)面片(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)12噸的(de)(de)(de)吊車勾(gou)(gou)住鐵鉤的(de)(de)(de)另一(yi)端(duan)，將波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)墊(dian)層上，然后使(shi)(shi)(shi)用(yong)(yong)同樣的(de)(de)(de)辦法將第二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)按(an)圖(tu)3、21斷(duan)面所示的(de)(de)(de)搭接(jie)(jie)方式(shi)放置(zhi)，使(shi)(shi)(shi)用(yong)(yong)撬棍將管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)口對齊，將提前準備好的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)螺(luo)(luo)紋(wen)(wen)部涂上渢滑劑，由內冋外插入孔位；波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)外側套上凹墊(dian)圈或凸墊(dian)圈，遇波(bo)(bo)使(shi)(shi)(shi)用(yong)(yong)凸墊(dian)圈，遇波(bo)(bo)峰使(shi)(shi)(shi)用(yong)(yong)凹墊(dian)圈墊(dian)圈外側旋上螺(luo)(luo)母，在用(yong)(yong)套筒扳(ban)手預緊(jin)螺(luo)(luo)母，然后使(shi)(shi)(shi)用(yong)(yong)電動(dong)扳(ban)手緊(jin)固螺(luo)(luo)母兩塊(kuai)板(ban)片(pian)(pian)(pian)(pian)洤全(quan)部安(an)裝(zhuang)(zhuang)(zhuang)完(wan)畢;波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)安(an)裝(zhuang)(zhuang)(zhuang)完(wan)畢后，需(xu)采用(yong)(yong)專用(yong)(yong)注膠槍于(yu)端(duan)部接(jie)(jie)合處、緊(jin)回件連接(jie)(jie)的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)孔空隙處涂抹中性硅(gui)酮耐候膠。緊(jin)接(jie)(jie)著(zhu)按(an)2#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)施工拼(pin)裝(zhuang)(zhuang)(zhuang)順(shun)序(xu)，拼(pin)裝(zhuang)(zhuang)(zhuang)好首(shou)圈波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圖(tu)36偶數(shu)、奇數(shu)斷(duan)面交替拼(pin)裝(zhuang)(zhuang)(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當波紋管涵(han)直徑較大(da)、填土(tu)高(gao)度較高(gao)時，必須設置加(jia)強管片，稱為加(jia)強圈”，加(jia)強斷面的管片安(an)裝工序(xu)。
