大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼裝支架:搭(da)(da)設腳手(shou)架根(gen)據波紋(wen)管(guan)(guan)的(de)直(zhi)(zhi)徑提前(qian)確定(ding)，采(cai)用管(guan)(guan)扣連接(jie)鋼管(guan)(guan)的(de)方式搭(da)(da)設腳手(shou)架，形式分A型(xing)和B型(xing)腳手(shou)架長度一般長25m、克0、6m、高(gao)為2d3(d為波紋(wen)管(guan)(guan)直(zhi)(zhi)徑)，B型(xing)腳手(shou)架一般克為25m高(gao)依據波紋(wen)管(guan)(guan)直(zhi)(zhi)徑大小(xiao)拼裝接(jie)縫位置確定(ding)尺寸。腳手(shou)架按上述尺寸搭(da)(da)設便于施工(gong)、

2、拼(pin)裝(zhuang)類型與搭(da)接方式：拼(pin)裝(zhuang)以中心(xin)軸(zhou)線為基準(zhun)，由中心(xin)向兩端(duan)對稱進行安(an)裝(zhuang)，直至兩端(duan)。1斷面(mian)(奇數(shu)斷面(mian))、Ⅱ斷面(mian)(偶(ou)(ou)數(shu)斷面(mian))、加(jia)強(qiang)斷面(mian)(偶(ou)(ou)數(shu)斷管管片）

3、波(bo)紋(wen)管(guan)拼裝(zhuang)(zhuang)：采用刻(ke)槽法施(shi)工的地基，安裝(zhuang)(zhuang)吊車依(yi)據刻(ke)槽深度，依(yi)次安裝(zhuang)(zhuang)底部管(guan)片(pian)。底部管(guan)片(pian)安裝(zhuang)(zhuang)完成后對剩余(yu)管(guan)片(pian)進行安裝(zhuang)(zhuang)。管(guan)片(pian)安裝(zhuang)(zhuang)同平基上的鋼波(bo)紋(wen)管(guan)施(shi)工。

首圈(quan)(quan)波(bo)(bo)(bo)紋(wen)管(guan)(guan)圈(quan)(quan)為奇數斷(duan)面，拼(pin)裝(zhuang)(zhuang)時應將(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于地上(shang)(shang)安裝(zhuang)(zhuang)，使(shi)用鐵鉤的(de)(de)(de)(de)(de)(de)一端(duan)勾(gou)住(zhu)I斷(duan)面片(pian)(pian)(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)螺(luo)(luo)(luo)絲囗，用12噸的(de)(de)(de)(de)(de)(de)吊(diao)車勾(gou)住(zhu)鐵鉤的(de)(de)(de)(de)(de)(de)另一端(duan)，將(jiang)波(bo)(bo)(bo)紋(wen)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于墊(dian)層上(shang)(shang)，然后(hou)(hou)使(shi)用同樣的(de)(de)(de)(de)(de)(de)辦法將(jiang)第(di)二片(pian)(pian)(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)按(an)圖3、21斷(duan)面所示的(de)(de)(de)(de)(de)(de)搭接(jie)方式放(fang)置，使(shi)用撬(qiao)棍將(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)口對齊，將(jiang)提前準備好(hao)的(de)(de)(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋(wen)部涂(tu)上(shang)(shang)渢(feng)滑劑，由內冋外插入孔位；波(bo)(bo)(bo)紋(wen)管(guan)(guan)外側套上(shang)(shang)凹墊(dian)圈(quan)(quan)或(huo)凸墊(dian)圈(quan)(quan)，遇波(bo)(bo)(bo)使(shi)用凸墊(dian)圈(quan)(quan)，遇波(bo)(bo)(bo)峰使(shi)用凹墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外側旋(xuan)上(shang)(shang)螺(luo)(luo)(luo)母(mu)，在用套筒扳手預緊螺(luo)(luo)(luo)母(mu)，然后(hou)(hou)使(shi)用電動扳手緊固螺(luo)(luo)(luo)母(mu)兩塊(kuai)板片(pian)(pian)(pian)(pian)(pian)洤(quan)全部安裝(zhuang)(zhuang)完畢(bi);波(bo)(bo)(bo)紋(wen)管(guan)(guan)的(de)(de)(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)安裝(zhuang)(zhuang)完畢(bi)后(hou)(hou)，需采用專(zhuan)用注膠(jiao)槍于端(duan)部接(jie)合處、緊回件連(lian)接(jie)的(de)(de)(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)孔空隙處涂(tu)抹(mo)中(zhong)性硅酮耐候(hou)膠(jiao)。緊接(jie)著(zhu)按(an)2#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、5#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、3#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、4#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)(de)(de)(de)施工拼(pin)裝(zhuang)(zhuang)順序，拼(pin)裝(zhuang)(zhuang)好(hao)首圈(quan)(quan)波(bo)(bo)(bo)紋(wen)管(guan)(guan)圖36偶數、奇數斷(duan)面交(jiao)替(ti)拼(pin)裝(zhuang)(zhuang)順序

4、加強斷面拼裝

當(dang)波紋管涵(han)直徑較大、填土高(gao)度(du)較高(gao)時，必(bi)須(xu)設置加強管片，稱為加強圈”，加強斷(duan)面的管片安裝(zhuang)工序。
