大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝(zhuang)支架(jia):搭設(she)腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)根(gen)據波紋管(guan)的(de)直(zhi)徑提前確定，采用管(guan)扣連接鋼管(guan)的(de)方(fang)式(shi)搭設(she)腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)，形式(shi)分A型和B型腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)長度一般長25m、克0、6m、高(gao)為2d3(d為波紋管(guan)直(zhi)徑)，B型腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)一般克為25m高(gao)依據波紋管(guan)直(zhi)徑大小拼裝(zhuang)接縫位(wei)置確定尺寸(cun)。腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)按上述尺寸(cun)搭設(she)便于施工、

2、拼裝類型與搭接方式：拼裝以中心(xin)軸線為基準，由(you)中心(xin)向兩端對稱進行安(an)裝，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(jia)強斷(duan)(duan)面(mian)(偶數斷(duan)(duan)管管片）

3、波紋(wen)管拼(pin)裝：采用刻槽(cao)法施工的(de)地(di)基，安裝吊車依據刻槽(cao)深度，依次安裝底(di)部(bu)管片。底(di)部(bu)管片安裝完成后(hou)對剩(sheng)余管片進行安裝。管片安裝同平基上的(de)鋼波紋(wen)管施工。

首圈波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)圈為(wei)奇數(shu)斷(duan)面(mian)，拼裝(zhuang)時應將管(guan)(guan)(guan)(guan)片(pian)立于地(di)上安裝(zhuang)，使(shi)(shi)用(yong)(yong)(yong)(yong)鐵鉤的(de)一端(duan)勾住(zhu)I斷(duan)面(mian)片(pian)(1#管(guan)(guan)(guan)(guan)片(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)螺(luo)絲囗，用(yong)(yong)(yong)(yong)12噸的(de)吊車勾住(zhu)鐵鉤的(de)另一端(duan)，將波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)片(pian)立于墊(dian)(dian)層(ceng)上，然后使(shi)(shi)用(yong)(yong)(yong)(yong)同樣(yang)的(de)辦法(fa)將第二片(pian)(6#管(guan)(guan)(guan)(guan)片(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)按圖(tu)3、21斷(duan)面(mian)所示的(de)搭接(jie)方式(shi)放置，使(shi)(shi)用(yong)(yong)(yong)(yong)撬棍將管(guan)(guan)(guan)(guan)片(pian)的(de)螺(luo)栓口對齊，將提前準備好的(de)螺(luo)栓螺(luo)紋(wen)部涂上渢滑劑，由內冋外(wai)(wai)插入孔(kong)位；波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)外(wai)(wai)側(ce)套(tao)上凹墊(dian)(dian)圈或凸墊(dian)(dian)圈，遇波(bo)(bo)使(shi)(shi)用(yong)(yong)(yong)(yong)凸墊(dian)(dian)圈，遇波(bo)(bo)峰使(shi)(shi)用(yong)(yong)(yong)(yong)凹墊(dian)(dian)圈墊(dian)(dian)圈外(wai)(wai)側(ce)旋上螺(luo)母(mu)，在(zai)用(yong)(yong)(yong)(yong)套(tao)筒(tong)扳手預緊(jin)螺(luo)母(mu)，然后使(shi)(shi)用(yong)(yong)(yong)(yong)電動扳手緊(jin)固螺(luo)母(mu)兩(liang)塊板片(pian)洤全部安裝(zhuang)完(wan)畢(bi);波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)的(de)螺(luo)栓安裝(zhuang)完(wan)畢(bi)后，需(xu)采用(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)注膠(jiao)槍于端(duan)部接(jie)合處(chu)、緊(jin)回件連接(jie)的(de)螺(luo)栓孔(kong)空隙處(chu)涂抹中(zhong)性硅(gui)酮耐(nai)候膠(jiao)。緊(jin)接(jie)著(zhu)按2#管(guan)(guan)(guan)(guan)片(pian)、5#管(guan)(guan)(guan)(guan)片(pian)、3#管(guan)(guan)(guan)(guan)片(pian)、4#管(guan)(guan)(guan)(guan)片(pian)的(de)施(shi)工拼裝(zhuang)順(shun)序(xu)，拼裝(zhuang)好首圈波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)圖(tu)36偶數(shu)、奇數(shu)斷(duan)面(mian)交(jiao)替(ti)拼裝(zhuang)順(shun)序(xu)

4、加強斷面拼裝

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