大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝(zhuang)支(zhi)架(jia)(jia):搭(da)設(she)腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)(jia)根據波(bo)紋(wen)管(guan)(guan)的直(zhi)(zhi)徑提前確定，采用管(guan)(guan)扣連接鋼管(guan)(guan)的方(fang)式搭(da)設(she)腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)(jia)，形式分(fen)A型和B型腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)(jia)長度一般長25m、克(ke)0、6m、高為2d3(d為波(bo)紋(wen)管(guan)(guan)直(zhi)(zhi)徑)，B型腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)(jia)一般克(ke)為25m高依(yi)據波(bo)紋(wen)管(guan)(guan)直(zhi)(zhi)徑大小拼裝(zhuang)接縫位置確定尺(chi)寸。腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)(jia)按上述(shu)尺(chi)寸搭(da)設(she)便于(yu)施(shi)工、

2、拼裝類型與(yu)搭接方式：拼裝以(yi)中心軸線為(wei)基準，由(you)中心向兩端(duan)對稱(cheng)進行安裝，直至兩端(duan)。1斷(duan)面(mian)(奇數(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數(shu)斷(duan)面(mian))、加強(qiang)斷(duan)面(mian)(偶數(shu)斷(duan)管管片）

3、波(bo)紋管(guan)(guan)拼裝(zhuang)(zhuang)(zhuang)：采(cai)用刻槽法(fa)施工(gong)的地基(ji)，安(an)裝(zhuang)(zhuang)(zhuang)吊(diao)車依據刻槽深度，依次安(an)裝(zhuang)(zhuang)(zhuang)底部管(guan)(guan)片。底部管(guan)(guan)片安(an)裝(zhuang)(zhuang)(zhuang)完成后對剩余(yu)管(guan)(guan)片進(jin)行安(an)裝(zhuang)(zhuang)(zhuang)。管(guan)(guan)片安(an)裝(zhuang)(zhuang)(zhuang)同平基(ji)上的鋼波(bo)紋管(guan)(guan)施工(gong)。

首(shou)(shou)圈(quan)(quan)波(bo)紋(wen)管(guan)(guan)圈(quan)(quan)為奇(qi)數斷面，拼(pin)裝(zhuang)(zhuang)時應將(jiang)(jiang)管(guan)(guan)片(pian)(pian)(pian)立于地上安(an)裝(zhuang)(zhuang)，使(shi)用鐵鉤(gou)(gou)的(de)(de)(de)(de)一(yi)端(duan)勾(gou)住I斷面片(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)(luo)絲囗，用12噸的(de)(de)(de)(de)吊(diao)車勾(gou)住鐵鉤(gou)(gou)的(de)(de)(de)(de)另一(yi)端(duan)，將(jiang)(jiang)波(bo)紋(wen)管(guan)(guan)片(pian)(pian)(pian)立于墊(dian)(dian)層上，然后(hou)(hou)使(shi)用同樣的(de)(de)(de)(de)辦法將(jiang)(jiang)第二片(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)按圖3、21斷面所示的(de)(de)(de)(de)搭接(jie)方(fang)式放(fang)置，使(shi)用撬棍(gun)將(jiang)(jiang)管(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)口對齊，將(jiang)(jiang)提前準(zhun)備好的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋(wen)部(bu)涂(tu)上渢滑劑，由內冋外(wai)插入孔位(wei)；波(bo)紋(wen)管(guan)(guan)外(wai)側套上凹墊(dian)(dian)圈(quan)(quan)或(huo)凸墊(dian)(dian)圈(quan)(quan)，遇波(bo)使(shi)用凸墊(dian)(dian)圈(quan)(quan)，遇波(bo)峰使(shi)用凹墊(dian)(dian)圈(quan)(quan)墊(dian)(dian)圈(quan)(quan)外(wai)側旋上螺(luo)(luo)(luo)母(mu)(mu)，在用套筒(tong)扳手(shou)預緊(jin)螺(luo)(luo)(luo)母(mu)(mu)，然后(hou)(hou)使(shi)用電動扳手(shou)緊(jin)固螺(luo)(luo)(luo)母(mu)(mu)兩塊(kuai)板片(pian)(pian)(pian)洤全部(bu)安(an)裝(zhuang)(zhuang)完(wan)畢;波(bo)紋(wen)管(guan)(guan)的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)安(an)裝(zhuang)(zhuang)完(wan)畢后(hou)(hou)，需采用專用注膠槍于端(duan)部(bu)接(jie)合處(chu)、緊(jin)回件連接(jie)的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)孔空隙處(chu)涂(tu)抹中性硅(gui)酮耐候膠。緊(jin)接(jie)著(zhu)按2#管(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)(de)施工(gong)拼(pin)裝(zhuang)(zhuang)順(shun)序(xu)，拼(pin)裝(zhuang)(zhuang)好首(shou)(shou)圈(quan)(quan)波(bo)紋(wen)管(guan)(guan)圖36偶數、奇(qi)數斷面交(jiao)替拼(pin)裝(zhuang)(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當(dang)波紋管(guan)(guan)涵直徑較大、填土高(gao)度較高(gao)時，必須設置加強(qiang)管(guan)(guan)片，稱為(wei)加強(qiang)圈”，加強(qiang)斷面的(de)管(guan)(guan)片安裝工序。
