大直徑鋼波紋管拼裝方法你知道嗎?
1、搭(da)設(she)拼裝支(zhi)架:搭(da)設(she)腳(jiao)手架根據波紋管(guan)的直徑(jing)提前確定,采(cai)用(yong)管(guan)扣連接(jie)鋼管(guan)的方(fang)式搭(da)設(she)腳(jiao)手架,形式分A型(xing)(xing)和B型(xing)(xing)腳(jiao)手架長(chang)度一般長(chang)25m、克0、6m、高為2d3(d為波紋管(guan)直徑(jing)),B型(xing)(xing)腳(jiao)手架一般克為25m高依據波紋管(guan)直徑(jing)大小(xiao)拼裝接(jie)縫位(wei)置確定尺(chi)寸(cun)。腳(jiao)手架按上述尺(chi)寸(cun)搭(da)設(she)便(bian)于施工、
2、拼裝(zhuang)類型與搭(da)接方式(shi):拼裝(zhuang)以中(zhong)心軸線(xian)為(wei)基準(zhun),由中(zhong)心向(xiang)兩端對(dui)稱進行(xing)安裝(zhuang),直至兩端。1斷(duan)面(mian)(奇數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶(ou)數斷(duan)面(mian))、加強斷(duan)面(mian)(偶(ou)數斷(duan)管管片(pian))
3、波紋(wen)管(guan)拼裝:采用刻槽法施(shi)(shi)工的地基,安(an)裝吊車依(yi)(yi)據刻槽深度,依(yi)(yi)次安(an)裝底(di)部管(guan)片。底(di)部管(guan)片安(an)裝完成后(hou)對剩余管(guan)片進行安(an)裝。管(guan)片安(an)裝同平基上的鋼(gang)波紋(wen)管(guan)施(shi)(shi)工。
首圈(quan)(quan)波(bo)紋(wen)管(guan)(guan)(guan)(guan)圈(quan)(quan)為奇數(shu)斷(duan)面(mian),拼(pin)(pin)裝時應將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)立(li)于地(di)上(shang)(shang)安裝,使用(yong)(yong)鐵鉤的(de)一端勾住I斷(duan)面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)螺(luo)絲囗,用(yong)(yong)12噸的(de)吊車勾住鐵鉤的(de)另一端,將(jiang)波(bo)紋(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)立(li)于墊(dian)層上(shang)(shang),然(ran)(ran)后(hou)使用(yong)(yong)同樣的(de)辦法將(jiang)第(di)二片(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)按(an)圖3、21斷(duan)面(mian)所(suo)示的(de)搭接方式(shi)放置,使用(yong)(yong)撬棍將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)的(de)螺(luo)栓(shuan)口對齊,將(jiang)提前準備好(hao)的(de)螺(luo)栓(shuan)螺(luo)紋(wen)部涂上(shang)(shang)渢滑(hua)劑,由(you)內冋外插入孔位;波(bo)紋(wen)管(guan)(guan)(guan)(guan)外側套上(shang)(shang)凹墊(dian)圈(quan)(quan)或凸墊(dian)圈(quan)(quan),遇波(bo)使用(yong)(yong)凸墊(dian)圈(quan)(quan),遇波(bo)峰(feng)使用(yong)(yong)凹墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外側旋上(shang)(shang)螺(luo)母,在用(yong)(yong)套筒扳(ban)手(shou)預緊螺(luo)母,然(ran)(ran)后(hou)使用(yong)(yong)電動(dong)扳(ban)手(shou)緊固螺(luo)母兩塊板片(pian)(pian)洤(quan)全部安裝完畢;波(bo)紋(wen)管(guan)(guan)(guan)(guan)的(de)螺(luo)栓(shuan)安裝完畢后(hou),需采用(yong)(yong)專用(yong)(yong)注膠(jiao)槍(qiang)于端部接合(he)處、緊回件連接的(de)螺(luo)栓(shuan)孔空隙處涂抹中性硅(gui)酮耐候膠(jiao)。緊接著按(an)2#管(guan)(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)的(de)施工拼(pin)(pin)裝順序,拼(pin)(pin)裝好(hao)首圈(quan)(quan)波(bo)紋(wen)管(guan)(guan)(guan)(guan)圖36偶數(shu)、奇數(shu)斷(duan)面(mian)交替拼(pin)(pin)裝順序
4、加強斷面拼裝
當波紋(wen)管(guan)(guan)涵(han)直徑較大、填土高度(du)較高時,必(bi)須設置加強(qiang)管(guan)(guan)片,稱為加強(qiang)圈”,加強(qiang)斷面的(de)管(guan)(guan)片安裝工(gong)序。
