大直徑鋼波紋管拼裝方法你知道嗎?
1、搭設拼裝支架(jia)(jia):搭設腳(jiao)手(shou)架(jia)(jia)根據(ju)波紋(wen)(wen)管(guan)的(de)直(zhi)徑(jing)提(ti)前(qian)確(que)定,采(cai)用管(guan)扣連接鋼管(guan)的(de)方式(shi)搭設腳(jiao)手(shou)架(jia)(jia),形(xing)式(shi)分A型(xing)和B型(xing)腳(jiao)手(shou)架(jia)(jia)長(chang)度一(yi)般長(chang)25m、克0、6m、高為2d3(d為波紋(wen)(wen)管(guan)直(zhi)徑(jing)),B型(xing)腳(jiao)手(shou)架(jia)(jia)一(yi)般克為25m高依據(ju)波紋(wen)(wen)管(guan)直(zhi)徑(jing)大小(xiao)拼裝接縫位置(zhi)確(que)定尺寸(cun)。腳(jiao)手(shou)架(jia)(jia)按(an)上(shang)述(shu)尺寸(cun)搭設便于施工、
2、拼裝類型與搭(da)接方式:拼裝以中心軸線為基準,由中心向兩(liang)端對稱進行(xing)安裝,直至兩(liang)端。1斷(duan)面(mian)(奇(qi)數(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶(ou)數(shu)斷(duan)面(mian))、加強(qiang)斷(duan)面(mian)(偶(ou)數(shu)斷(duan)管管片)
3、波紋(wen)(wen)管(guan)拼裝(zhuang)(zhuang)(zhuang):采用刻(ke)槽法施工的(de)地基,安(an)裝(zhuang)(zhuang)(zhuang)吊車(che)依(yi)據刻(ke)槽深度,依(yi)次(ci)安(an)裝(zhuang)(zhuang)(zhuang)底(di)(di)部管(guan)片(pian)。底(di)(di)部管(guan)片(pian)安(an)裝(zhuang)(zhuang)(zhuang)完(wan)成后對剩余管(guan)片(pian)進行安(an)裝(zhuang)(zhuang)(zhuang)。管(guan)片(pian)安(an)裝(zhuang)(zhuang)(zhuang)同平(ping)基上的(de)鋼波紋(wen)(wen)管(guan)施工。
首(shou)圈波(bo)紋管(guan)圈為奇數斷面,拼(pin)裝(zhuang)(zhuang)(zhuang)時應將(jiang)管(guan)片(pian)(pian)立于(yu)地上安(an)裝(zhuang)(zhuang)(zhuang),使用(yong)鐵(tie)鉤的(de)(de)一端勾住I斷面片(pian)(pian)(1#管(guan)片(pian)(pian))波(bo)紋管(guan)管(guan)片(pian)(pian)螺(luo)(luo)(luo)(luo)絲囗,用(yong)12噸的(de)(de)吊車勾住鐵(tie)鉤的(de)(de)另一端,將(jiang)波(bo)紋管(guan)片(pian)(pian)立于(yu)墊(dian)層上,然后使用(yong)同(tong)樣的(de)(de)辦(ban)法(fa)將(jiang)第二片(pian)(pian)(6#管(guan)片(pian)(pian))波(bo)紋管(guan)管(guan)片(pian)(pian)按圖3、21斷面所示的(de)(de)搭接(jie)(jie)方式放(fang)置,使用(yong)撬棍將(jiang)管(guan)片(pian)(pian)的(de)(de)螺(luo)(luo)(luo)(luo)栓口對齊(qi),將(jiang)提前準備好的(de)(de)螺(luo)(luo)(luo)(luo)栓螺(luo)(luo)(luo)(luo)紋部涂(tu)上渢滑劑(ji),由內冋外(wai)插(cha)入孔位;波(bo)紋管(guan)外(wai)側(ce)(ce)套上凹墊(dian)圈或(huo)凸墊(dian)圈,遇波(bo)使用(yong)凸墊(dian)圈,遇波(bo)峰使用(yong)凹墊(dian)圈墊(dian)圈外(wai)側(ce)(ce)旋上螺(luo)(luo)(luo)(luo)母,在用(yong)套筒扳手預緊(jin)螺(luo)(luo)(luo)(luo)母,然后使用(yong)電動扳手緊(jin)固螺(luo)(luo)(luo)(luo)母兩塊(kuai)板片(pian)(pian)洤(quan)全部安(an)裝(zhuang)(zhuang)(zhuang)完畢(bi);波(bo)紋管(guan)的(de)(de)螺(luo)(luo)(luo)(luo)栓安(an)裝(zhuang)(zhuang)(zhuang)完畢(bi)后,需采(cai)用(yong)專用(yong)注膠槍于(yu)端部接(jie)(jie)合處、緊(jin)回件連接(jie)(jie)的(de)(de)螺(luo)(luo)(luo)(luo)栓孔空隙處涂(tu)抹中性硅酮耐候(hou)膠。緊(jin)接(jie)(jie)著(zhu)按2#管(guan)片(pian)(pian)、5#管(guan)片(pian)(pian)、3#管(guan)片(pian)(pian)、4#管(guan)片(pian)(pian)的(de)(de)施工(gong)拼(pin)裝(zhuang)(zhuang)(zhuang)順序,拼(pin)裝(zhuang)(zhuang)(zhuang)好首(shou)圈波(bo)紋管(guan)圖36偶數、奇數斷面交替拼(pin)裝(zhuang)(zhuang)(zhuang)順序
4、加強斷面拼裝
當(dang)波紋(wen)管涵直徑(jing)較大、填(tian)土(tu)高度較高時,必須(xu)設(she)置(zhi)加(jia)強管片(pian),稱為加(jia)強圈”,加(jia)強斷面的管片(pian)安(an)裝工序(xu)。
