大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝支(zhi)架(jia):搭設(she)腳(jiao)(jiao)手(shou)架(jia)根據(ju)波(bo)紋(wen)管(guan)的直徑提前確定(ding)，采用(yong)管(guan)扣連接(jie)鋼(gang)管(guan)的方(fang)式(shi)搭設(she)腳(jiao)(jiao)手(shou)架(jia)，形(xing)式(shi)分A型和(he)B型腳(jiao)(jiao)手(shou)架(jia)長度一般(ban)長25m、克(ke)0、6m、高(gao)為2d3(d為波(bo)紋(wen)管(guan)直徑)，B型腳(jiao)(jiao)手(shou)架(jia)一般(ban)克(ke)為25m高(gao)依(yi)據(ju)波(bo)紋(wen)管(guan)直徑大小拼裝接(jie)縫位置確定(ding)尺寸。腳(jiao)(jiao)手(shou)架(jia)按上述(shu)尺寸搭設(she)便于施(shi)工、

2、拼裝類型與搭接方(fang)式：拼裝以中心軸(zhou)線(xian)為基準，由中心向兩端(duan)對(dui)稱進行安裝，直至兩端(duan)。1斷面(mian)(mian)(mian)(奇數(shu)斷面(mian)(mian)(mian))、Ⅱ斷面(mian)(mian)(mian)(偶數(shu)斷面(mian)(mian)(mian))、加(jia)強斷面(mian)(mian)(mian)(偶數(shu)斷管(guan)(guan)管(guan)(guan)片）

3、波(bo)紋(wen)(wen)管(guan)拼裝：采用刻槽(cao)法施(shi)工的地基，安(an)(an)裝吊車依(yi)據刻槽(cao)深(shen)度(du)，依(yi)次安(an)(an)裝底(di)部管(guan)片(pian)。底(di)部管(guan)片(pian)安(an)(an)裝完(wan)成后對(dui)剩余管(guan)片(pian)進行安(an)(an)裝。管(guan)片(pian)安(an)(an)裝同平基上的鋼波(bo)紋(wen)(wen)管(guan)施(shi)工。

首圈(quan)(quan)波(bo)紋(wen)管圈(quan)(quan)為(wei)奇數(shu)斷(duan)(duan)面，拼(pin)(pin)裝時應將(jiang)管片(pian)立(li)于地上(shang)安裝，使(shi)(shi)用(yong)鐵鉤的(de)(de)(de)(de)(de)(de)一端勾住I斷(duan)(duan)面片(pian)(1#管片(pian))波(bo)紋(wen)管管片(pian)螺(luo)絲囗，用(yong)12噸(dun)的(de)(de)(de)(de)(de)(de)吊車勾住鐵鉤的(de)(de)(de)(de)(de)(de)另一端，將(jiang)波(bo)紋(wen)管片(pian)立(li)于墊(dian)(dian)(dian)層(ceng)上(shang)，然后使(shi)(shi)用(yong)同(tong)樣(yang)的(de)(de)(de)(de)(de)(de)辦法將(jiang)第二片(pian)(6#管片(pian))波(bo)紋(wen)管管片(pian)按圖3、21斷(duan)(duan)面所示的(de)(de)(de)(de)(de)(de)搭(da)接(jie)(jie)方(fang)式放置，使(shi)(shi)用(yong)撬棍將(jiang)管片(pian)的(de)(de)(de)(de)(de)(de)螺(luo)栓(shuan)口對齊，將(jiang)提前準(zhun)備好(hao)的(de)(de)(de)(de)(de)(de)螺(luo)栓(shuan)螺(luo)紋(wen)部涂(tu)(tu)上(shang)渢滑劑，由內冋外插入孔(kong)位；波(bo)紋(wen)管外側(ce)套上(shang)凹墊(dian)(dian)(dian)圈(quan)(quan)或凸墊(dian)(dian)(dian)圈(quan)(quan)，遇波(bo)使(shi)(shi)用(yong)凸墊(dian)(dian)(dian)圈(quan)(quan)，遇波(bo)峰使(shi)(shi)用(yong)凹墊(dian)(dian)(dian)圈(quan)(quan)墊(dian)(dian)(dian)圈(quan)(quan)外側(ce)旋上(shang)螺(luo)母，在用(yong)套筒扳手預緊螺(luo)母，然后使(shi)(shi)用(yong)電(dian)動(dong)扳手緊固螺(luo)母兩(liang)塊板片(pian)洤全部安裝完(wan)畢(bi)(bi);波(bo)紋(wen)管的(de)(de)(de)(de)(de)(de)螺(luo)栓(shuan)安裝完(wan)畢(bi)(bi)后，需采用(yong)專用(yong)注膠槍于端部接(jie)(jie)合(he)處、緊回件連接(jie)(jie)的(de)(de)(de)(de)(de)(de)螺(luo)栓(shuan)孔(kong)空隙處涂(tu)(tu)抹中性硅酮耐候膠。緊接(jie)(jie)著(zhu)按2#管片(pian)、5#管片(pian)、3#管片(pian)、4#管片(pian)的(de)(de)(de)(de)(de)(de)施工(gong)拼(pin)(pin)裝順序，拼(pin)(pin)裝好(hao)首圈(quan)(quan)波(bo)紋(wen)管圖36偶數(shu)、奇數(shu)斷(duan)(duan)面交替拼(pin)(pin)裝順序

4、加強斷面拼裝

當波紋(wen)管(guan)涵(han)直徑較大、填(tian)土高(gao)度較高(gao)時，必須設置加強管(guan)片，稱為加強圈”，加強斷面的管(guan)片安(an)裝工序。
