大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼裝支架(jia):搭(da)設腳手(shou)(shou)架(jia)根據波(bo)(bo)紋(wen)管(guan)的直(zhi)徑(jing)提(ti)前確(que)定，采用管(guan)扣連接鋼(gang)管(guan)的方式(shi)搭(da)設腳手(shou)(shou)架(jia)，形式(shi)分A型(xing)和B型(xing)腳手(shou)(shou)架(jia)長度一(yi)般長25m、克0、6m、高(gao)為(wei)(wei)2d3(d為(wei)(wei)波(bo)(bo)紋(wen)管(guan)直(zhi)徑(jing))，B型(xing)腳手(shou)(shou)架(jia)一(yi)般克為(wei)(wei)25m高(gao)依(yi)據波(bo)(bo)紋(wen)管(guan)直(zhi)徑(jing)大(da)小拼裝接縫位置確(que)定尺寸。腳手(shou)(shou)架(jia)按上述尺寸搭(da)設便于施工、

2、拼裝(zhuang)(zhuang)類型與搭(da)接方式：拼裝(zhuang)(zhuang)以中(zhong)心(xin)軸(zhou)線為基準，由中(zhong)心(xin)向兩端對稱進(jin)行安裝(zhuang)(zhuang)，直至兩端。1斷(duan)面(mian)(奇(qi)數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數斷(duan)面(mian))、加強斷(duan)面(mian)(偶數斷(duan)管管片(pian)）

3、波(bo)紋管(guan)(guan)拼(pin)裝：采用(yong)刻槽法施工的(de)地基(ji)，安(an)裝吊車依據(ju)刻槽深度，依次安(an)裝底(di)部(bu)管(guan)(guan)片(pian)(pian)。底(di)部(bu)管(guan)(guan)片(pian)(pian)安(an)裝完成后對(dui)剩余管(guan)(guan)片(pian)(pian)進行(xing)安(an)裝。管(guan)(guan)片(pian)(pian)安(an)裝同平基(ji)上的(de)鋼波(bo)紋管(guan)(guan)施工。

首圈波(bo)(bo)紋管(guan)圈為奇(qi)數(shu)斷面(mian)(mian)，拼(pin)裝(zhuang)時應將(jiang)管(guan)片(pian)立于地上安(an)裝(zhuang)，使用(yong)(yong)鐵鉤的(de)(de)(de)一(yi)端勾住(zhu)I斷面(mian)(mian)片(pian)(1#管(guan)片(pian))波(bo)(bo)紋管(guan)管(guan)片(pian)螺(luo)(luo)(luo)(luo)絲囗，用(yong)(yong)12噸(dun)的(de)(de)(de)吊車勾住(zhu)鐵鉤的(de)(de)(de)另一(yi)端，將(jiang)波(bo)(bo)紋管(guan)片(pian)立于墊(dian)層上，然(ran)后(hou)使用(yong)(yong)同樣的(de)(de)(de)辦法將(jiang)第二(er)片(pian)(6#管(guan)片(pian))波(bo)(bo)紋管(guan)管(guan)片(pian)按圖3、21斷面(mian)(mian)所示的(de)(de)(de)搭接(jie)(jie)方式放置(zhi)，使用(yong)(yong)撬棍將(jiang)管(guan)片(pian)的(de)(de)(de)螺(luo)(luo)(luo)(luo)栓口對齊，將(jiang)提前(qian)準(zhun)備(bei)好的(de)(de)(de)螺(luo)(luo)(luo)(luo)栓螺(luo)(luo)(luo)(luo)紋部涂上渢滑劑，由內冋(jiong)外(wai)插入孔(kong)位(wei)；波(bo)(bo)紋管(guan)外(wai)側(ce)套上凹(ao)墊(dian)圈或凸墊(dian)圈，遇波(bo)(bo)使用(yong)(yong)凸墊(dian)圈，遇波(bo)(bo)峰(feng)使用(yong)(yong)凹(ao)墊(dian)圈墊(dian)圈外(wai)側(ce)旋上螺(luo)(luo)(luo)(luo)母(mu)(mu)，在用(yong)(yong)套筒扳手預緊螺(luo)(luo)(luo)(luo)母(mu)(mu)，然(ran)后(hou)使用(yong)(yong)電(dian)動扳手緊固螺(luo)(luo)(luo)(luo)母(mu)(mu)兩塊板(ban)片(pian)洤(quan)全(quan)部安(an)裝(zhuang)完(wan)(wan)畢(bi);波(bo)(bo)紋管(guan)的(de)(de)(de)螺(luo)(luo)(luo)(luo)栓安(an)裝(zhuang)完(wan)(wan)畢(bi)后(hou)，需采用(yong)(yong)專用(yong)(yong)注膠(jiao)槍于端部接(jie)(jie)合處(chu)、緊回件(jian)連(lian)接(jie)(jie)的(de)(de)(de)螺(luo)(luo)(luo)(luo)栓孔(kong)空隙(xi)處(chu)涂抹中性硅酮耐(nai)候膠(jiao)。緊接(jie)(jie)著按2#管(guan)片(pian)、5#管(guan)片(pian)、3#管(guan)片(pian)、4#管(guan)片(pian)的(de)(de)(de)施(shi)工拼(pin)裝(zhuang)順序，拼(pin)裝(zhuang)好首圈波(bo)(bo)紋管(guan)圖36偶(ou)數(shu)、奇(qi)數(shu)斷面(mian)(mian)交替拼(pin)裝(zhuang)順序

4、加強斷面拼裝

當波(bo)紋管(guan)涵(han)直徑(jing)較大、填土高度較高時(shi)，必須設置加強(qiang)管(guan)片，稱為(wei)加強(qiang)圈”，加強(qiang)斷面的管(guan)片安裝工(gong)序。
