大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)(da)設(she)(she)拼裝(zhuang)支(zhi)架(jia):搭(da)(da)(da)設(she)(she)腳手架(jia)根(gen)據波(bo)紋(wen)管(guan)的直(zhi)(zhi)徑(jing)(jing)提前確(que)定(ding)(ding)，采(cai)用管(guan)扣連接鋼(gang)管(guan)的方(fang)式搭(da)(da)(da)設(she)(she)腳手架(jia)，形(xing)式分A型(xing)和(he)B型(xing)腳手架(jia)長度一般長25m、克0、6m、高為(wei)2d3(d為(wei)波(bo)紋(wen)管(guan)直(zhi)(zhi)徑(jing)(jing))，B型(xing)腳手架(jia)一般克為(wei)25m高依據波(bo)紋(wen)管(guan)直(zhi)(zhi)徑(jing)(jing)大小(xiao)拼裝(zhuang)接縫位置(zhi)確(que)定(ding)(ding)尺寸(cun)。腳手架(jia)按(an)上述尺寸(cun)搭(da)(da)(da)設(she)(she)便(bian)于施工、

2、拼(pin)裝類型與搭(da)接方式：拼(pin)裝以中心軸(zhou)線為(wei)基準，由中心向兩端(duan)對稱(cheng)進行(xing)安裝，直至兩端(duan)。1斷(duan)面(mian)(奇(qi)數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶(ou)數斷(duan)面(mian))、加強斷(duan)面(mian)(偶(ou)數斷(duan)管管片）

3、波紋(wen)管(guan)拼裝(zhuang)(zhuang)：采用刻槽法(fa)施工(gong)的地(di)基，安(an)(an)(an)裝(zhuang)(zhuang)吊車依(yi)據刻槽深(shen)度，依(yi)次安(an)(an)(an)裝(zhuang)(zhuang)底(di)(di)部(bu)管(guan)片。底(di)(di)部(bu)管(guan)片安(an)(an)(an)裝(zhuang)(zhuang)完(wan)成(cheng)后對剩余管(guan)片進行安(an)(an)(an)裝(zhuang)(zhuang)。管(guan)片安(an)(an)(an)裝(zhuang)(zhuang)同(tong)平(ping)基上的鋼波紋(wen)管(guan)施工(gong)。

首(shou)圈(quan)(quan)(quan)波(bo)(bo)紋管(guan)(guan)圈(quan)(quan)(quan)為(wei)奇(qi)數(shu)斷(duan)面，拼(pin)裝(zhuang)時應將(jiang)(jiang)管(guan)(guan)片(pian)(pian)(pian)立于地上安(an)(an)裝(zhuang)，使(shi)用(yong)鐵鉤的(de)(de)一端勾住I斷(duan)面片(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)紋管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)絲囗，用(yong)12噸的(de)(de)吊車勾住鐵鉤的(de)(de)另一端，將(jiang)(jiang)波(bo)(bo)紋管(guan)(guan)片(pian)(pian)(pian)立于墊(dian)層上，然(ran)(ran)后使(shi)用(yong)同樣的(de)(de)辦法將(jiang)(jiang)第二片(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)紋管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)按圖3、21斷(duan)面所示的(de)(de)搭接(jie)方式放置，使(shi)用(yong)撬棍將(jiang)(jiang)管(guan)(guan)片(pian)(pian)(pian)的(de)(de)螺(luo)(luo)栓(shuan)口(kou)對齊，將(jiang)(jiang)提(ti)前準(zhun)備好(hao)的(de)(de)螺(luo)(luo)栓(shuan)螺(luo)(luo)紋部涂(tu)上渢滑劑，由(you)內冋外插入孔(kong)(kong)位；波(bo)(bo)紋管(guan)(guan)外側(ce)套上凹墊(dian)圈(quan)(quan)(quan)或凸墊(dian)圈(quan)(quan)(quan)，遇(yu)波(bo)(bo)使(shi)用(yong)凸墊(dian)圈(quan)(quan)(quan)，遇(yu)波(bo)(bo)峰使(shi)用(yong)凹墊(dian)圈(quan)(quan)(quan)墊(dian)圈(quan)(quan)(quan)外側(ce)旋上螺(luo)(luo)母，在用(yong)套筒(tong)扳手(shou)預(yu)緊(jin)螺(luo)(luo)母，然(ran)(ran)后使(shi)用(yong)電動(dong)扳手(shou)緊(jin)固螺(luo)(luo)母兩塊板片(pian)(pian)(pian)洤全部安(an)(an)裝(zhuang)完畢;波(bo)(bo)紋管(guan)(guan)的(de)(de)螺(luo)(luo)栓(shuan)安(an)(an)裝(zhuang)完畢后，需采(cai)用(yong)專(zhuan)用(yong)注膠槍于端部接(jie)合處、緊(jin)回(hui)件連(lian)接(jie)的(de)(de)螺(luo)(luo)栓(shuan)孔(kong)(kong)空隙處涂(tu)抹(mo)中性硅酮耐(nai)候膠。緊(jin)接(jie)著按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)施工拼(pin)裝(zhuang)順(shun)序，拼(pin)裝(zhuang)好(hao)首(shou)圈(quan)(quan)(quan)波(bo)(bo)紋管(guan)(guan)圖36偶(ou)數(shu)、奇(qi)數(shu)斷(duan)面交替(ti)拼(pin)裝(zhuang)順(shun)序

4、加強斷面拼裝

當波紋(wen)管(guan)(guan)涵直徑(jing)較大、填土(tu)高度(du)較高時，必(bi)須設置加(jia)(jia)強管(guan)(guan)片，稱為(wei)加(jia)(jia)強圈(quan)”，加(jia)(jia)強斷面的(de)管(guan)(guan)片安裝(zhuang)工(gong)序。
