大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)(she)(she)拼(pin)(pin)裝支(zhi)架(jia)(jia):搭(da)設(she)(she)(she)腳(jiao)手架(jia)(jia)根據波(bo)紋管的直(zhi)徑(jing)(jing)提前確定，采用管扣連接鋼管的方式搭(da)設(she)(she)(she)腳(jiao)手架(jia)(jia)，形式分A型(xing)和(he)B型(xing)腳(jiao)手架(jia)(jia)長度一般長25m、克0、6m、高(gao)為(wei)2d3(d為(wei)波(bo)紋管直(zhi)徑(jing)(jing))，B型(xing)腳(jiao)手架(jia)(jia)一般克為(wei)25m高(gao)依(yi)據波(bo)紋管直(zhi)徑(jing)(jing)大(da)小拼(pin)(pin)裝接縫(feng)位(wei)置確定尺寸(cun)。腳(jiao)手架(jia)(jia)按上述尺寸(cun)搭(da)設(she)(she)(she)便于施(shi)工、

2、拼(pin)(pin)裝(zhuang)類型與搭(da)接方式(shi)：拼(pin)(pin)裝(zhuang)以中心軸線為基準，由中心向兩(liang)端(duan)(duan)對稱(cheng)進行安裝(zhuang)，直(zhi)至兩(liang)端(duan)(duan)。1斷(duan)(duan)(duan)面(mian)(mian)(奇數斷(duan)(duan)(duan)面(mian)(mian))、Ⅱ斷(duan)(duan)(duan)面(mian)(mian)(偶數斷(duan)(duan)(duan)面(mian)(mian))、加(jia)強斷(duan)(duan)(duan)面(mian)(mian)(偶數斷(duan)(duan)(duan)管管片）

3、波紋(wen)管拼裝(zhuang)(zhuang)：采用刻槽法(fa)施工的地(di)基(ji)，安(an)(an)裝(zhuang)(zhuang)吊車依據刻槽深度，依次安(an)(an)裝(zhuang)(zhuang)底(di)部管片(pian)(pian)。底(di)部管片(pian)(pian)安(an)(an)裝(zhuang)(zhuang)完成后對剩余管片(pian)(pian)進行(xing)安(an)(an)裝(zhuang)(zhuang)。管片(pian)(pian)安(an)(an)裝(zhuang)(zhuang)同平基(ji)上的鋼(gang)波紋(wen)管施工。

首(shou)圈(quan)波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)圈(quan)為奇數斷面，拼裝(zhuang)時應將(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立(li)于(yu)(yu)地上(shang)安裝(zhuang)，使(shi)用(yong)(yong)鐵鉤(gou)的(de)(de)一端(duan)勾(gou)住I斷面片(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)絲囗(wei)，用(yong)(yong)12噸的(de)(de)吊車勾(gou)住鐵鉤(gou)的(de)(de)另(ling)一端(duan)，將(jiang)波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立(li)于(yu)(yu)墊(dian)層(ceng)上(shang)，然(ran)后(hou)使(shi)用(yong)(yong)同樣的(de)(de)辦法將(jiang)第二(er)片(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)按(an)圖3、21斷面所示的(de)(de)搭接方式放置(zhi)，使(shi)用(yong)(yong)撬(qiao)棍將(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)螺(luo)(luo)栓(shuan)(shuan)(shuan)口對齊，將(jiang)提前準備(bei)好的(de)(de)螺(luo)(luo)栓(shuan)(shuan)(shuan)螺(luo)(luo)紋(wen)部涂上(shang)渢滑(hua)劑，由內冋外(wai)(wai)插(cha)入孔位；波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)外(wai)(wai)側套(tao)上(shang)凹墊(dian)圈(quan)或凸墊(dian)圈(quan)，遇(yu)波(bo)使(shi)用(yong)(yong)凸墊(dian)圈(quan)，遇(yu)波(bo)峰使(shi)用(yong)(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外(wai)(wai)側旋(xuan)上(shang)螺(luo)(luo)母(mu)，在用(yong)(yong)套(tao)筒扳手預緊(jin)(jin)螺(luo)(luo)母(mu)，然(ran)后(hou)使(shi)用(yong)(yong)電動(dong)扳手緊(jin)(jin)固(gu)螺(luo)(luo)母(mu)兩塊板(ban)片(pian)(pian)(pian)(pian)洤全部安裝(zhuang)完畢;波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)的(de)(de)螺(luo)(luo)栓(shuan)(shuan)(shuan)安裝(zhuang)完畢后(hou)，需(xu)采用(yong)(yong)專用(yong)(yong)注膠(jiao)槍于(yu)(yu)端(duan)部接合處(chu)、緊(jin)(jin)回(hui)件連接的(de)(de)螺(luo)(luo)栓(shuan)(shuan)(shuan)孔空隙處(chu)涂抹中性硅酮耐候(hou)膠(jiao)。緊(jin)(jin)接著按(an)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)施工(gong)拼裝(zhuang)順(shun)序，拼裝(zhuang)好首(shou)圈(quan)波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)圖36偶數、奇數斷面交替拼裝(zhuang)順(shun)序

4、加強斷面拼裝

當(dang)波紋管(guan)涵直徑(jing)較大、填土高度較高時，必須設置加強管(guan)片，稱(cheng)為(wei)加強圈(quan)”，加強斷面的(de)管(guan)片安裝工序。
