大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)(she)拼裝支架:搭(da)(da)設(she)(she)腳(jiao)手(shou)(shou)架根據(ju)波(bo)紋(wen)(wen)管(guan)的直(zhi)徑(jing)提前確(que)定，采用(yong)管(guan)扣連接鋼管(guan)的方式搭(da)(da)設(she)(she)腳(jiao)手(shou)(shou)架，形式分A型和B型腳(jiao)手(shou)(shou)架長(chang)度(du)一般(ban)長(chang)25m、克0、6m、高為(wei)2d3(d為(wei)波(bo)紋(wen)(wen)管(guan)直(zhi)徑(jing))，B型腳(jiao)手(shou)(shou)架一般(ban)克為(wei)25m高依(yi)據(ju)波(bo)紋(wen)(wen)管(guan)直(zhi)徑(jing)大小拼裝接縫(feng)位置確(que)定尺寸。腳(jiao)手(shou)(shou)架按上述(shu)尺寸搭(da)(da)設(she)(she)便于施工、

2、拼(pin)裝(zhuang)(zhuang)類型與搭接方式(shi)：拼(pin)裝(zhuang)(zhuang)以中心(xin)(xin)軸線為基(ji)準，由中心(xin)(xin)向兩端(duan)對稱進行(xing)安裝(zhuang)(zhuang)，直至兩端(duan)。1斷(duan)面(mian)(奇數(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數(shu)斷(duan)面(mian))、加強斷(duan)面(mian)(偶數(shu)斷(duan)管管片）

3、波紋(wen)管拼裝(zhuang)：采用刻槽法施(shi)工的地基，安(an)裝(zhuang)吊車依據(ju)刻槽深度，依次安(an)裝(zhuang)底(di)部管片。底(di)部管片安(an)裝(zhuang)完(wan)成后對剩(sheng)余管片進行(xing)安(an)裝(zhuang)。管片安(an)裝(zhuang)同平基上的鋼波紋(wen)管施(shi)工。

鋼波紋管

首(shou)圈(quan)(quan)波紋(wen)(wen)(wen)管(guan)(guan)圈(quan)(quan)為奇數斷(duan)(duan)面(mian)，拼(pin)裝(zhuang)時應將(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)立(li)(li)于地上安裝(zhuang)，使(shi)用(yong)(yong)鐵鉤(gou)的一端(duan)勾住I斷(duan)(duan)面(mian)片(pian)(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian)(pian))波紋(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)絲囗，用(yong)(yong)12噸(dun)的吊車勾住鐵鉤(gou)的另一端(duan)，將(jiang)波紋(wen)(wen)(wen)管(guan)(guan)片(pian)(pian)(pian)(pian)立(li)(li)于墊(dian)(dian)(dian)(dian)層上，然后(hou)使(shi)用(yong)(yong)同樣的辦法將(jiang)第二(er)片(pian)(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian)(pian))波紋(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)按(an)圖3、21斷(duan)(duan)面(mian)所示的搭接(jie)(jie)(jie)方式放置，使(shi)用(yong)(yong)撬棍將(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)的螺(luo)栓(shuan)口對齊，將(jiang)提前(qian)準備(bei)好的螺(luo)栓(shuan)螺(luo)紋(wen)(wen)(wen)部涂上渢滑劑，由內冋(jiong)外插入孔位；波紋(wen)(wen)(wen)管(guan)(guan)外側套上凹墊(dian)(dian)(dian)(dian)圈(quan)(quan)或凸墊(dian)(dian)(dian)(dian)圈(quan)(quan)，遇(yu)波使(shi)用(yong)(yong)凸墊(dian)(dian)(dian)(dian)圈(quan)(quan)，遇(yu)波峰使(shi)用(yong)(yong)凹墊(dian)(dian)(dian)(dian)圈(quan)(quan)墊(dian)(dian)(dian)(dian)圈(quan)(quan)外側旋上螺(luo)母，在用(yong)(yong)套筒扳(ban)手預緊螺(luo)母，然后(hou)使(shi)用(yong)(yong)電動(dong)扳(ban)手緊固(gu)螺(luo)母兩(liang)塊(kuai)板片(pian)(pian)(pian)(pian)洤(quan)全部安裝(zhuang)完畢(bi);波紋(wen)(wen)(wen)管(guan)(guan)的螺(luo)栓(shuan)安裝(zhuang)完畢(bi)后(hou)，需采用(yong)(yong)專用(yong)(yong)注膠槍(qiang)于端(duan)部接(jie)(jie)(jie)合處(chu)(chu)、緊回件連接(jie)(jie)(jie)的螺(luo)栓(shuan)孔空(kong)隙處(chu)(chu)涂抹中(zhong)性硅酮耐候膠。緊接(jie)(jie)(jie)著按(an)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)的施工拼(pin)裝(zhuang)順(shun)序(xu)，拼(pin)裝(zhuang)好首(shou)圈(quan)(quan)波紋(wen)(wen)(wen)管(guan)(guan)圖36偶(ou)數、奇數斷(duan)(duan)面(mian)交(jiao)替拼(pin)裝(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當波(bo)紋管涵直徑較(jiao)大、填土(tu)高度較(jiao)高時(shi)，必須設置加強管片，稱為加強圈”，加強斷面(mian)的管片安裝(zhuang)工序。
