大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝支架(jia)(jia):搭設(she)腳(jiao)手架(jia)(jia)根據波(bo)紋管(guan)的直徑(jing)提前確(que)(que)定(ding)，采用管(guan)扣(kou)連接鋼管(guan)的方式搭設(she)腳(jiao)手架(jia)(jia)，形式分(fen)A型(xing)和B型(xing)腳(jiao)手架(jia)(jia)長度(du)一般(ban)長25m、克0、6m、高為(wei)2d3(d為(wei)波(bo)紋管(guan)直徑(jing))，B型(xing)腳(jiao)手架(jia)(jia)一般(ban)克為(wei)25m高依據波(bo)紋管(guan)直徑(jing)大(da)小(xiao)拼裝接縫位置確(que)(que)定(ding)尺寸。腳(jiao)手架(jia)(jia)按(an)上述(shu)尺寸搭設(she)便于施工、

2、拼裝(zhuang)類型(xing)與搭接方式：拼裝(zhuang)以中(zhong)心軸(zhou)線為基準，由中(zhong)心向(xiang)兩端對稱進(jin)行安裝(zhuang)，直至兩端。1斷(duan)(duan)面(mian)(奇數(shu)斷(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)面(mian)(偶(ou)(ou)數(shu)斷(duan)(duan)面(mian))、加強斷(duan)(duan)面(mian)(偶(ou)(ou)數(shu)斷(duan)(duan)管(guan)管(guan)片）

3、波(bo)紋管(guan)(guan)(guan)拼裝(zhuang)：采用刻槽法施工的(de)地基，安(an)裝(zhuang)吊(diao)車依據(ju)刻槽深度(du)，依次安(an)裝(zhuang)底(di)部管(guan)(guan)(guan)片。底(di)部管(guan)(guan)(guan)片安(an)裝(zhuang)完成后(hou)對(dui)剩余管(guan)(guan)(guan)片進(jin)行安(an)裝(zhuang)。管(guan)(guan)(guan)片安(an)裝(zhuang)同平基上的(de)鋼波(bo)紋管(guan)(guan)(guan)施工。

首圈波(bo)紋(wen)管(guan)圈為(wei)奇(qi)數(shu)斷(duan)面(mian)，拼(pin)裝(zhuang)時應將(jiang)管(guan)片(pian)(pian)立(li)于地上(shang)安(an)裝(zhuang)，使(shi)用(yong)(yong)(yong)鐵鉤的(de)(de)(de)一端勾住I斷(duan)面(mian)片(pian)(pian)(1#管(guan)片(pian)(pian))波(bo)紋(wen)管(guan)管(guan)片(pian)(pian)螺(luo)(luo)(luo)(luo)絲(si)囗，用(yong)(yong)(yong)12噸的(de)(de)(de)吊車(che)勾住鐵鉤的(de)(de)(de)另一端，將(jiang)波(bo)紋(wen)管(guan)片(pian)(pian)立(li)于墊(dian)(dian)(dian)層上(shang)，然后(hou)(hou)使(shi)用(yong)(yong)(yong)同樣的(de)(de)(de)辦(ban)法將(jiang)第二片(pian)(pian)(6#管(guan)片(pian)(pian))波(bo)紋(wen)管(guan)管(guan)片(pian)(pian)按(an)圖3、21斷(duan)面(mian)所(suo)示的(de)(de)(de)搭(da)接方式放置(zhi)，使(shi)用(yong)(yong)(yong)撬棍將(jiang)管(guan)片(pian)(pian)的(de)(de)(de)螺(luo)(luo)(luo)(luo)栓(shuan)口對齊，將(jiang)提前準備好(hao)的(de)(de)(de)螺(luo)(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)(luo)紋(wen)部涂上(shang)渢滑劑，由內(nei)冋外(wai)(wai)插(cha)入孔位；波(bo)紋(wen)管(guan)外(wai)(wai)側套上(shang)凹墊(dian)(dian)(dian)圈或凸墊(dian)(dian)(dian)圈，遇波(bo)使(shi)用(yong)(yong)(yong)凸墊(dian)(dian)(dian)圈，遇波(bo)峰使(shi)用(yong)(yong)(yong)凹墊(dian)(dian)(dian)圈墊(dian)(dian)(dian)圈外(wai)(wai)側旋上(shang)螺(luo)(luo)(luo)(luo)母(mu)，在(zai)用(yong)(yong)(yong)套筒(tong)扳手預緊螺(luo)(luo)(luo)(luo)母(mu)，然后(hou)(hou)使(shi)用(yong)(yong)(yong)電動(dong)扳手緊固螺(luo)(luo)(luo)(luo)母(mu)兩塊板(ban)片(pian)(pian)洤全(quan)部安(an)裝(zhuang)完(wan)畢;波(bo)紋(wen)管(guan)的(de)(de)(de)螺(luo)(luo)(luo)(luo)栓(shuan)安(an)裝(zhuang)完(wan)畢后(hou)(hou)，需(xu)采用(yong)(yong)(yong)專(zhuan)用(yong)(yong)(yong)注膠槍(qiang)于端部接合處(chu)、緊回件連接的(de)(de)(de)螺(luo)(luo)(luo)(luo)栓(shuan)孔空隙處(chu)涂抹(mo)中性硅酮耐候膠。緊接著按(an)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)(de)施工拼(pin)裝(zhuang)順(shun)序，拼(pin)裝(zhuang)好(hao)首圈波(bo)紋(wen)管(guan)圖36偶數(shu)、奇(qi)數(shu)斷(duan)面(mian)交替拼(pin)裝(zhuang)順(shun)序

4、加強斷面拼裝

當波(bo)紋管涵直徑較(jiao)大、填土高度(du)較(jiao)高時，必須設置加(jia)強管片，稱為加(jia)強圈”，加(jia)強斷面的管片安裝工序。
