大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)拼裝支架:搭(da)(da)設(she)腳(jiao)手(shou)(shou)架根據(ju)波(bo)紋管的(de)直徑提前確定，采用管扣連接鋼管的(de)方式搭(da)(da)設(she)腳(jiao)手(shou)(shou)架，形式分A型(xing)和B型(xing)腳(jiao)手(shou)(shou)架長度一(yi)(yi)般長25m、克0、6m、高為2d3(d為波(bo)紋管直徑)，B型(xing)腳(jiao)手(shou)(shou)架一(yi)(yi)般克為25m高依據(ju)波(bo)紋管直徑大(da)小拼裝接縫位(wei)置(zhi)確定尺(chi)寸。腳(jiao)手(shou)(shou)架按上述尺(chi)寸搭(da)(da)設(she)便于施工(gong)、

2、拼(pin)裝(zhuang)類型(xing)與搭接方式：拼(pin)裝(zhuang)以(yi)中(zhong)心(xin)軸線為基準，由中(zhong)心(xin)向兩端對稱進行安裝(zhuang)，直至兩端。1斷(duan)(duan)面(mian)(奇數斷(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)面(mian)(偶數斷(duan)(duan)面(mian))、加強(qiang)斷(duan)(duan)面(mian)(偶數斷(duan)(duan)管管片）

3、波(bo)紋管(guan)(guan)拼(pin)裝：采用(yong)刻(ke)(ke)槽法施(shi)(shi)工的地基，安裝吊(diao)車依(yi)據(ju)刻(ke)(ke)槽深(shen)度，依(yi)次安裝底部管(guan)(guan)片(pian)。底部管(guan)(guan)片(pian)安裝完成后對剩余管(guan)(guan)片(pian)進行安裝。管(guan)(guan)片(pian)安裝同平基上的鋼波(bo)紋管(guan)(guan)施(shi)(shi)工。

首圈(quan)波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)圈(quan)為奇數斷(duan)面(mian)(mian)(mian)，拼裝(zhuang)時應(ying)將(jiang)管(guan)(guan)(guan)(guan)片立于地(di)上(shang)安(an)(an)裝(zhuang)，使(shi)用(yong)(yong)(yong)鐵(tie)(tie)鉤的(de)一(yi)端勾住I斷(duan)面(mian)(mian)(mian)片(1#管(guan)(guan)(guan)(guan)片)波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片螺(luo)絲囗，用(yong)(yong)(yong)12噸(dun)的(de)吊(diao)車勾住鐵(tie)(tie)鉤的(de)另一(yi)端，將(jiang)波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)片立于墊(dian)層上(shang)，然后使(shi)用(yong)(yong)(yong)同樣的(de)辦法將(jiang)第二片(6#管(guan)(guan)(guan)(guan)片)波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片按圖(tu)3、21斷(duan)面(mian)(mian)(mian)所示(shi)的(de)搭(da)接(jie)方式放置，使(shi)用(yong)(yong)(yong)撬(qiao)棍將(jiang)管(guan)(guan)(guan)(guan)片的(de)螺(luo)栓口(kou)對齊(qi)，將(jiang)提前(qian)準備好(hao)的(de)螺(luo)栓螺(luo)紋部(bu)涂上(shang)渢滑劑，由內冋外插入(ru)孔位；波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)外側(ce)(ce)套上(shang)凹墊(dian)圈(quan)或(huo)凸墊(dian)圈(quan)，遇(yu)波(bo)(bo)(bo)(bo)使(shi)用(yong)(yong)(yong)凸墊(dian)圈(quan)，遇(yu)波(bo)(bo)(bo)(bo)峰使(shi)用(yong)(yong)(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外側(ce)(ce)旋上(shang)螺(luo)母(mu)，在用(yong)(yong)(yong)套筒扳(ban)手預緊螺(luo)母(mu)，然后使(shi)用(yong)(yong)(yong)電(dian)動扳(ban)手緊固螺(luo)母(mu)兩塊板片洤全部(bu)安(an)(an)裝(zhuang)完(wan)畢;波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)的(de)螺(luo)栓安(an)(an)裝(zhuang)完(wan)畢后，需采(cai)用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠槍于端部(bu)接(jie)合處(chu)、緊回件連接(jie)的(de)螺(luo)栓孔空隙處(chu)涂抹中(zhong)性硅酮耐候膠。緊接(jie)著按2#管(guan)(guan)(guan)(guan)片、5#管(guan)(guan)(guan)(guan)片、3#管(guan)(guan)(guan)(guan)片、4#管(guan)(guan)(guan)(guan)片的(de)施工拼裝(zhuang)順(shun)序，拼裝(zhuang)好(hao)首圈(quan)波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)圖(tu)36偶數、奇數斷(duan)面(mian)(mian)(mian)交(jiao)替(ti)拼裝(zhuang)順(shun)序

4、加強斷面拼裝

當波紋管(guan)涵直徑較(jiao)大(da)、填土(tu)高度較(jiao)高時，必(bi)須(xu)設(she)置加(jia)強(qiang)管(guan)片(pian)，稱為加(jia)強(qiang)圈”，加(jia)強(qiang)斷(duan)面的管(guan)片(pian)安(an)裝(zhuang)工序。
