大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)(she)(she)拼裝支架(jia):搭設(she)(she)(she)腳(jiao)手架(jia)根據(ju)波(bo)紋(wen)(wen)管(guan)的直徑提前確定(ding)，采用管(guan)扣連接鋼管(guan)的方式(shi)搭設(she)(she)(she)腳(jiao)手架(jia)，形式(shi)分A型(xing)和B型(xing)腳(jiao)手架(jia)長度一(yi)般(ban)長25m、克0、6m、高(gao)(gao)為2d3(d為波(bo)紋(wen)(wen)管(guan)直徑)，B型(xing)腳(jiao)手架(jia)一(yi)般(ban)克為25m高(gao)(gao)依據(ju)波(bo)紋(wen)(wen)管(guan)直徑大小拼裝接縫位(wei)置確定(ding)尺寸。腳(jiao)手架(jia)按上述(shu)尺寸搭設(she)(she)(she)便于施工、

2、拼裝類型(xing)與搭接方式：拼裝以中(zhong)心(xin)軸線為基準，由中(zhong)心(xin)向兩(liang)端(duan)對稱進行安裝，直(zhi)至(zhi)兩(liang)端(duan)。1斷面(mian)(mian)(mian)(奇數(shu)(shu)斷面(mian)(mian)(mian))、Ⅱ斷面(mian)(mian)(mian)(偶數(shu)(shu)斷面(mian)(mian)(mian))、加強斷面(mian)(mian)(mian)(偶數(shu)(shu)斷管(guan)管(guan)片）

3、波紋管(guan)(guan)(guan)拼裝(zhuang)(zhuang)：采用刻槽法施工的地基(ji)，安(an)(an)(an)裝(zhuang)(zhuang)吊車依據刻槽深度，依次安(an)(an)(an)裝(zhuang)(zhuang)底(di)部(bu)(bu)管(guan)(guan)(guan)片。底(di)部(bu)(bu)管(guan)(guan)(guan)片安(an)(an)(an)裝(zhuang)(zhuang)完成后(hou)對剩余管(guan)(guan)(guan)片進行(xing)安(an)(an)(an)裝(zhuang)(zhuang)。管(guan)(guan)(guan)片安(an)(an)(an)裝(zhuang)(zhuang)同平基(ji)上的鋼波紋管(guan)(guan)(guan)施工。

首(shou)圈波紋(wen)管(guan)圈為(wei)奇數(shu)斷(duan)(duan)(duan)面(mian)，拼裝(zhuang)(zhuang)(zhuang)(zhuang)時應將(jiang)管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)立于地上安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)，使(shi)用(yong)鐵(tie)鉤的(de)(de)一(yi)端勾住(zhu)I斷(duan)(duan)(duan)面(mian)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(1#管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian))波紋(wen)管(guan)管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)螺(luo)(luo)絲囗(wei)，用(yong)12噸(dun)的(de)(de)吊車勾住(zhu)鐵(tie)鉤的(de)(de)另一(yi)端，將(jiang)波紋(wen)管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)立于墊(dian)(dian)(dian)層上，然后使(shi)用(yong)同(tong)樣的(de)(de)辦法(fa)將(jiang)第二片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(6#管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian))波紋(wen)管(guan)管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)按(an)圖3、21斷(duan)(duan)(duan)面(mian)所示的(de)(de)搭接(jie)方(fang)式放置，使(shi)用(yong)撬棍將(jiang)管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)的(de)(de)螺(luo)(luo)栓口對齊，將(jiang)提前(qian)準備好的(de)(de)螺(luo)(luo)栓螺(luo)(luo)紋(wen)部涂上渢滑劑(ji)，由內冋外插入孔(kong)位；波紋(wen)管(guan)外側(ce)套(tao)上凹墊(dian)(dian)(dian)圈或凸墊(dian)(dian)(dian)圈，遇(yu)波使(shi)用(yong)凸墊(dian)(dian)(dian)圈，遇(yu)波峰使(shi)用(yong)凹墊(dian)(dian)(dian)圈墊(dian)(dian)(dian)圈外側(ce)旋上螺(luo)(luo)母，在用(yong)套(tao)筒(tong)扳手預緊(jin)螺(luo)(luo)母，然后使(shi)用(yong)電(dian)動扳手緊(jin)固螺(luo)(luo)母兩塊板片(pian)(pian)(pian)(pian)(pian)(pian)(pian)洤全部安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)完(wan)畢;波紋(wen)管(guan)的(de)(de)螺(luo)(luo)栓安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)完(wan)畢后，需采用(yong)專用(yong)注膠槍(qiang)于端部接(jie)合處、緊(jin)回(hui)件連接(jie)的(de)(de)螺(luo)(luo)栓孔(kong)空(kong)隙處涂抹中(zhong)性(xing)硅酮耐(nai)候膠。緊(jin)接(jie)著按(an)2#管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)、5#管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)、3#管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)、4#管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)的(de)(de)施工(gong)拼裝(zhuang)(zhuang)(zhuang)(zhuang)順序，拼裝(zhuang)(zhuang)(zhuang)(zhuang)好首(shou)圈波紋(wen)管(guan)圖36偶數(shu)、奇數(shu)斷(duan)(duan)(duan)面(mian)交替拼裝(zhuang)(zhuang)(zhuang)(zhuang)順序

4、加強斷面拼裝

當(dang)波紋管(guan)(guan)涵直徑較大、填(tian)土高度較高時，必(bi)須設置(zhi)加強(qiang)(qiang)管(guan)(guan)片(pian)，稱為加強(qiang)(qiang)圈”，加強(qiang)(qiang)斷(duan)面(mian)的管(guan)(guan)片(pian)安裝工序。
