大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼裝(zhuang)支架(jia)(jia):搭(da)(da)設腳(jiao)手(shou)架(jia)(jia)根據波(bo)紋(wen)管(guan)的(de)(de)直徑提前確(que)定(ding)，采用(yong)管(guan)扣連接(jie)鋼管(guan)的(de)(de)方式搭(da)(da)設腳(jiao)手(shou)架(jia)(jia)，形式分(fen)A型(xing)(xing)和B型(xing)(xing)腳(jiao)手(shou)架(jia)(jia)長度一般(ban)長25m、克(ke)0、6m、高為2d3(d為波(bo)紋(wen)管(guan)直徑)，B型(xing)(xing)腳(jiao)手(shou)架(jia)(jia)一般(ban)克(ke)為25m高依據波(bo)紋(wen)管(guan)直徑大小拼裝(zhuang)接(jie)縫位置確(que)定(ding)尺寸(cun)。腳(jiao)手(shou)架(jia)(jia)按上述尺寸(cun)搭(da)(da)設便于施工(gong)、

2、拼裝(zhuang)類型(xing)與(yu)搭接方式(shi)：拼裝(zhuang)以中心(xin)軸線為基準(zhun)，由中心(xin)向兩(liang)(liang)端對稱進行安裝(zhuang)，直(zhi)至兩(liang)(liang)端。1斷(duan)面(mian)(奇數(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數(shu)斷(duan)面(mian))、加(jia)強斷(duan)面(mian)(偶數(shu)斷(duan)管管片）

3、波紋管(guan)(guan)拼(pin)裝(zhuang)：采用刻(ke)槽法(fa)施工的地基，安(an)(an)裝(zhuang)吊車依據刻(ke)槽深度，依次安(an)(an)裝(zhuang)底(di)部管(guan)(guan)片(pian)。底(di)部管(guan)(guan)片(pian)安(an)(an)裝(zhuang)完成后對剩余管(guan)(guan)片(pian)進行安(an)(an)裝(zhuang)。管(guan)(guan)片(pian)安(an)(an)裝(zhuang)同(tong)平基上的鋼波紋管(guan)(guan)施工。

首(shou)圈(quan)(quan)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圈(quan)(quan)為奇(qi)數(shu)斷面，拼(pin)(pin)裝(zhuang)時應將(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)地(di)上(shang)安裝(zhuang)，使(shi)用鐵(tie)鉤(gou)的(de)(de)(de)一端勾住(zhu)I斷面片(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)絲(si)囗，用12噸(dun)的(de)(de)(de)吊車勾住(zhu)鐵(tie)鉤(gou)的(de)(de)(de)另一端，將(jiang)(jiang)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)墊層上(shang)，然后(hou)使(shi)用同樣(yang)的(de)(de)(de)辦法將(jiang)(jiang)第(di)二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)按圖(tu)3、21斷面所示(shi)的(de)(de)(de)搭接(jie)(jie)方式放置(zhi)，使(shi)用撬棍(gun)將(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)螺(luo)(luo)栓(shuan)口(kou)對齊，將(jiang)(jiang)提(ti)前準備好(hao)的(de)(de)(de)螺(luo)(luo)栓(shuan)螺(luo)(luo)紋(wen)(wen)(wen)部涂(tu)上(shang)渢滑劑，由內冋(jiong)外插入孔位；波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)外側(ce)套(tao)上(shang)凹墊圈(quan)(quan)或凸墊圈(quan)(quan)，遇(yu)波(bo)(bo)使(shi)用凸墊圈(quan)(quan)，遇(yu)波(bo)(bo)峰使(shi)用凹墊圈(quan)(quan)墊圈(quan)(quan)外側(ce)旋上(shang)螺(luo)(luo)母(mu)，在用套(tao)筒扳手預緊(jin)螺(luo)(luo)母(mu)，然后(hou)使(shi)用電動(dong)扳手緊(jin)固螺(luo)(luo)母(mu)兩塊板片(pian)(pian)(pian)(pian)洤全部安裝(zhuang)完畢;波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)螺(luo)(luo)栓(shuan)安裝(zhuang)完畢后(hou)，需采用專用注膠(jiao)(jiao)槍于(yu)端部接(jie)(jie)合處、緊(jin)回件(jian)連接(jie)(jie)的(de)(de)(de)螺(luo)(luo)栓(shuan)孔空隙處涂(tu)抹中性硅酮耐候膠(jiao)(jiao)。緊(jin)接(jie)(jie)著按2#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)施工(gong)拼(pin)(pin)裝(zhuang)順序，拼(pin)(pin)裝(zhuang)好(hao)首(shou)圈(quan)(quan)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圖(tu)36偶數(shu)、奇(qi)數(shu)斷面交(jiao)替拼(pin)(pin)裝(zhuang)順序

4、加強斷面拼裝

當(dang)波紋管(guan)涵(han)直徑較大、填土高度較高時，必(bi)須設置加強(qiang)管(guan)片(pian)，稱為加強(qiang)圈”，加強(qiang)斷面的管(guan)片(pian)安裝工(gong)序。
