大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)(she)拼(pin)裝支架(jia):搭(da)(da)設(she)(she)腳(jiao)手架(jia)根據波(bo)紋(wen)管(guan)的直(zhi)(zhi)徑(jing)提前確(que)定(ding)，采用管(guan)扣連接鋼管(guan)的方(fang)式搭(da)(da)設(she)(she)腳(jiao)手架(jia)，形式分(fen)A型和(he)B型腳(jiao)手架(jia)長度一(yi)般長25m、克0、6m、高為2d3(d為波(bo)紋(wen)管(guan)直(zhi)(zhi)徑(jing))，B型腳(jiao)手架(jia)一(yi)般克為25m高依據波(bo)紋(wen)管(guan)直(zhi)(zhi)徑(jing)大小拼(pin)裝接縫(feng)位置(zhi)確(que)定(ding)尺寸(cun)。腳(jiao)手架(jia)按(an)上述尺寸(cun)搭(da)(da)設(she)(she)便于施(shi)工、

2、拼裝(zhuang)(zhuang)類型與搭接方式：拼裝(zhuang)(zhuang)以中心軸線為基準(zhun)，由中心向兩端(duan)對(dui)稱(cheng)進行安裝(zhuang)(zhuang)，直(zhi)至兩端(duan)。1斷面(mian)(mian)(奇數斷面(mian)(mian))、Ⅱ斷面(mian)(mian)(偶數斷面(mian)(mian))、加(jia)強斷面(mian)(mian)(偶數斷管管片）

3、波紋管(guan)拼(pin)裝(zhuang)：采用刻槽法施工的地基，安(an)(an)裝(zhuang)吊車依據刻槽深(shen)度(du)，依次安(an)(an)裝(zhuang)底部管(guan)片。底部管(guan)片安(an)(an)裝(zhuang)完成后對(dui)剩(sheng)余管(guan)片進行安(an)(an)裝(zhuang)。管(guan)片安(an)(an)裝(zhuang)同平(ping)基上的鋼波紋管(guan)施工。

首圈(quan)(quan)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)圈(quan)(quan)為奇數斷(duan)(duan)面，拼裝(zhuang)時應將管(guan)(guan)片(pian)(pian)(pian)立(li)于(yu)地上安(an)裝(zhuang)，使(shi)用(yong)(yong)(yong)(yong)鐵(tie)(tie)鉤的(de)(de)一(yi)端(duan)勾(gou)(gou)住I斷(duan)(duan)面片(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)螺(luo)絲(si)囗，用(yong)(yong)(yong)(yong)12噸的(de)(de)吊車勾(gou)(gou)住鐵(tie)(tie)鉤的(de)(de)另(ling)一(yi)端(duan)，將波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)片(pian)(pian)(pian)立(li)于(yu)墊(dian)層上，然后(hou)使(shi)用(yong)(yong)(yong)(yong)同樣的(de)(de)辦(ban)法將第二(er)片(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)按(an)圖3、21斷(duan)(duan)面所(suo)示的(de)(de)搭接(jie)(jie)方式放置(zhi)，使(shi)用(yong)(yong)(yong)(yong)撬棍(gun)將管(guan)(guan)片(pian)(pian)(pian)的(de)(de)螺(luo)栓(shuan)口對齊，將提前準備(bei)好(hao)(hao)的(de)(de)螺(luo)栓(shuan)螺(luo)紋(wen)(wen)(wen)(wen)部(bu)涂上渢滑劑，由內冋外(wai)(wai)插(cha)入孔位；波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)外(wai)(wai)側套(tao)(tao)上凹(ao)墊(dian)圈(quan)(quan)或凸墊(dian)圈(quan)(quan)，遇波(bo)(bo)使(shi)用(yong)(yong)(yong)(yong)凸墊(dian)圈(quan)(quan)，遇波(bo)(bo)峰使(shi)用(yong)(yong)(yong)(yong)凹(ao)墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外(wai)(wai)側旋上螺(luo)母(mu)，在用(yong)(yong)(yong)(yong)套(tao)(tao)筒(tong)扳手預緊螺(luo)母(mu)，然后(hou)使(shi)用(yong)(yong)(yong)(yong)電動扳手緊固螺(luo)母(mu)兩塊板片(pian)(pian)(pian)洤全(quan)部(bu)安(an)裝(zhuang)完(wan)畢;波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)的(de)(de)螺(luo)栓(shuan)安(an)裝(zhuang)完(wan)畢后(hou)，需采用(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)注(zhu)膠(jiao)槍于(yu)端(duan)部(bu)接(jie)(jie)合(he)處、緊回件(jian)連接(jie)(jie)的(de)(de)螺(luo)栓(shuan)孔空隙處涂抹中性硅酮耐候膠(jiao)。緊接(jie)(jie)著按(an)2#管(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)片(pian)(pian)(pian)的(de)(de)施(shi)工(gong)拼裝(zhuang)順序(xu)，拼裝(zhuang)好(hao)(hao)首圈(quan)(quan)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)圖36偶數、奇數斷(duan)(duan)面交替拼裝(zhuang)順序(xu)

4、加強斷面拼裝

當(dang)波紋管(guan)涵(han)直徑(jing)較(jiao)大、填土高(gao)度較(jiao)高(gao)時，必(bi)須設置加強管(guan)片，稱為加強圈”，加強斷面的管(guan)片安裝工序。
