大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼(pin)裝支架(jia)(jia):搭(da)設腳(jiao)手(shou)架(jia)(jia)根據波(bo)紋(wen)管(guan)(guan)的直徑提前確定(ding)，采用管(guan)(guan)扣連接鋼管(guan)(guan)的方式搭(da)設腳(jiao)手(shou)架(jia)(jia)，形式分(fen)A型(xing)(xing)和B型(xing)(xing)腳(jiao)手(shou)架(jia)(jia)長度一(yi)般(ban)長25m、克0、6m、高為2d3(d為波(bo)紋(wen)管(guan)(guan)直徑)，B型(xing)(xing)腳(jiao)手(shou)架(jia)(jia)一(yi)般(ban)克為25m高依據波(bo)紋(wen)管(guan)(guan)直徑大(da)小(xiao)拼(pin)裝接縫位(wei)置確定(ding)尺寸(cun)。腳(jiao)手(shou)架(jia)(jia)按上述尺寸(cun)搭(da)設便于施(shi)工、

2、拼(pin)裝(zhuang)類型與搭(da)接方式：拼(pin)裝(zhuang)以中心軸(zhou)線為基準，由中心向兩端對稱進行安裝(zhuang)，直至兩端。1斷(duan)面(mian)(奇數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數斷(duan)面(mian))、加強(qiang)斷(duan)面(mian)(偶數斷(duan)管管片(pian)）

3、波紋管(guan)拼裝(zhuang)：采用刻(ke)槽(cao)法(fa)施(shi)工(gong)的(de)地基，安裝(zhuang)吊車依據(ju)刻(ke)槽(cao)深度，依次安裝(zhuang)底部(bu)管(guan)片。底部(bu)管(guan)片安裝(zhuang)完成后(hou)對(dui)剩余管(guan)片進行安裝(zhuang)。管(guan)片安裝(zhuang)同平基上(shang)的(de)鋼波紋管(guan)施(shi)工(gong)。

首(shou)圈(quan)(quan)波(bo)紋管圈(quan)(quan)為奇數(shu)斷(duan)面，拼裝(zhuang)(zhuang)(zhuang)時應(ying)將(jiang)(jiang)管片(pian)(pian)立于(yu)地上安(an)(an)裝(zhuang)(zhuang)(zhuang)，使(shi)(shi)用(yong)(yong)(yong)(yong)鐵(tie)鉤(gou)的(de)一端勾(gou)住I斷(duan)面片(pian)(pian)(1#管片(pian)(pian))波(bo)紋管管片(pian)(pian)螺(luo)(luo)(luo)絲囗，用(yong)(yong)(yong)(yong)12噸的(de)吊車勾(gou)住鐵(tie)鉤(gou)的(de)另一端，將(jiang)(jiang)波(bo)紋管片(pian)(pian)立于(yu)墊(dian)層上，然(ran)后(hou)使(shi)(shi)用(yong)(yong)(yong)(yong)同樣的(de)辦法將(jiang)(jiang)第二片(pian)(pian)(6#管片(pian)(pian))波(bo)紋管管片(pian)(pian)按圖3、21斷(duan)面所(suo)示(shi)的(de)搭接(jie)方式放置(zhi)，使(shi)(shi)用(yong)(yong)(yong)(yong)撬棍將(jiang)(jiang)管片(pian)(pian)的(de)螺(luo)(luo)(luo)栓口對齊，將(jiang)(jiang)提(ti)前準備(bei)好(hao)的(de)螺(luo)(luo)(luo)栓螺(luo)(luo)(luo)紋部涂上渢滑劑，由內冋外(wai)插入(ru)孔位；波(bo)紋管外(wai)側套上凹(ao)墊(dian)圈(quan)(quan)或凸墊(dian)圈(quan)(quan)，遇波(bo)使(shi)(shi)用(yong)(yong)(yong)(yong)凸墊(dian)圈(quan)(quan)，遇波(bo)峰使(shi)(shi)用(yong)(yong)(yong)(yong)凹(ao)墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外(wai)側旋上螺(luo)(luo)(luo)母(mu)，在用(yong)(yong)(yong)(yong)套筒扳手預緊(jin)(jin)螺(luo)(luo)(luo)母(mu)，然(ran)后(hou)使(shi)(shi)用(yong)(yong)(yong)(yong)電動扳手緊(jin)(jin)固螺(luo)(luo)(luo)母(mu)兩塊板片(pian)(pian)洤(quan)全(quan)部安(an)(an)裝(zhuang)(zhuang)(zhuang)完畢(bi);波(bo)紋管的(de)螺(luo)(luo)(luo)栓安(an)(an)裝(zhuang)(zhuang)(zhuang)完畢(bi)后(hou)，需采(cai)用(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)注(zhu)膠(jiao)槍于(yu)端部接(jie)合處(chu)、緊(jin)(jin)回件連接(jie)的(de)螺(luo)(luo)(luo)栓孔空隙處(chu)涂抹中性硅酮耐候(hou)膠(jiao)。緊(jin)(jin)接(jie)著按2#管片(pian)(pian)、5#管片(pian)(pian)、3#管片(pian)(pian)、4#管片(pian)(pian)的(de)施工拼裝(zhuang)(zhuang)(zhuang)順序，拼裝(zhuang)(zhuang)(zhuang)好(hao)首(shou)圈(quan)(quan)波(bo)紋管圖36偶數(shu)、奇數(shu)斷(duan)面交替(ti)拼裝(zhuang)(zhuang)(zhuang)順序

4、加強斷面拼裝

當波紋管涵直(zhi)徑較大、填土高度較高時，必須設置加(jia)強管片，稱(cheng)為加(jia)強圈(quan)”，加(jia)強斷(duan)面(mian)的(de)管片安(an)裝工序。
