大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝(zhuang)支架(jia):搭設腳(jiao)(jiao)手(shou)架(jia)根(gen)據波紋(wen)管(guan)的直(zhi)徑提前(qian)確定(ding)，采(cai)用管(guan)扣連接鋼管(guan)的方式搭設腳(jiao)(jiao)手(shou)架(jia)，形式分A型(xing)和B型(xing)腳(jiao)(jiao)手(shou)架(jia)長度(du)一般(ban)(ban)長25m、克(ke)0、6m、高為2d3(d為波紋(wen)管(guan)直(zhi)徑)，B型(xing)腳(jiao)(jiao)手(shou)架(jia)一般(ban)(ban)克(ke)為25m高依(yi)據波紋(wen)管(guan)直(zhi)徑大小拼(pin)裝(zhuang)接縫位置確定(ding)尺(chi)寸。腳(jiao)(jiao)手(shou)架(jia)按上(shang)述尺(chi)寸搭設便于施工、

2、拼裝類型與搭接方式：拼裝以中心軸線為基準(zhun)，由中心向兩端對(dui)稱進行安(an)裝，直至(zhi)兩端。1斷(duan)面(mian)(mian)(mian)(奇數(shu)斷(duan)面(mian)(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(mian)(偶(ou)數(shu)斷(duan)面(mian)(mian)(mian))、加(jia)強斷(duan)面(mian)(mian)(mian)(偶(ou)數(shu)斷(duan)管管片(pian)）

3、波(bo)紋管拼(pin)裝(zhuang)(zhuang)：采(cai)用刻槽法施工的(de)地基，安裝(zhuang)(zhuang)吊車依據刻槽深度，依次(ci)安裝(zhuang)(zhuang)底(di)部(bu)管片(pian)。底(di)部(bu)管片(pian)安裝(zhuang)(zhuang)完成后對剩余管片(pian)進行安裝(zhuang)(zhuang)。管片(pian)安裝(zhuang)(zhuang)同平基上的(de)鋼波(bo)紋管施工。

首(shou)圈(quan)(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)圈(quan)(quan)為奇(qi)(qi)數斷面(mian)，拼裝(zhuang)(zhuang)時應將(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)立于(yu)地上(shang)安裝(zhuang)(zhuang)，使(shi)用(yong)鐵鉤(gou)的(de)(de)(de)一(yi)端(duan)勾住I斷面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)(luo)絲囗，用(yong)12噸的(de)(de)(de)吊(diao)車(che)勾住鐵鉤(gou)的(de)(de)(de)另一(yi)端(duan)，將(jiang)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)立于(yu)墊(dian)層(ceng)上(shang)，然后使(shi)用(yong)同樣(yang)的(de)(de)(de)辦法將(jiang)第二片(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)按圖3、21斷面(mian)所(suo)示的(de)(de)(de)搭接方式放置，使(shi)用(yong)撬棍將(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)的(de)(de)(de)螺(luo)(luo)(luo)栓口對齊，將(jiang)提前準備好的(de)(de)(de)螺(luo)(luo)(luo)栓螺(luo)(luo)(luo)紋(wen)(wen)(wen)部涂上(shang)渢滑劑(ji)，由內冋外(wai)插入孔位；波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)外(wai)側(ce)套(tao)上(shang)凹墊(dian)圈(quan)(quan)或(huo)凸(tu)墊(dian)圈(quan)(quan)，遇(yu)波(bo)使(shi)用(yong)凸(tu)墊(dian)圈(quan)(quan)，遇(yu)波(bo)峰使(shi)用(yong)凹墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外(wai)側(ce)旋上(shang)螺(luo)(luo)(luo)母，在用(yong)套(tao)筒(tong)扳(ban)手預緊(jin)(jin)螺(luo)(luo)(luo)母，然后使(shi)用(yong)電動扳(ban)手緊(jin)(jin)固螺(luo)(luo)(luo)母兩塊板(ban)片(pian)(pian)洤(quan)全部安裝(zhuang)(zhuang)完畢(bi);波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)螺(luo)(luo)(luo)栓安裝(zhuang)(zhuang)完畢(bi)后，需采用(yong)專(zhuan)用(yong)注膠槍于(yu)端(duan)部接合處、緊(jin)(jin)回(hui)件(jian)連接的(de)(de)(de)螺(luo)(luo)(luo)栓孔空隙處涂抹(mo)中性硅酮耐候膠。緊(jin)(jin)接著按2#管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)的(de)(de)(de)施工(gong)拼裝(zhuang)(zhuang)順序(xu)，拼裝(zhuang)(zhuang)好首(shou)圈(quan)(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)(guan)圖36偶數、奇(qi)(qi)數斷面(mian)交替拼裝(zhuang)(zhuang)順序(xu)

4、加強斷面拼裝

當波(bo)紋管涵直徑較大、填土高度(du)較高時，必須設置加(jia)(jia)強管片，稱為(wei)加(jia)(jia)強圈”，加(jia)(jia)強斷(duan)面的管片安裝(zhuang)工(gong)序。
