大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼(pin)裝支架(jia):搭(da)設(she)腳(jiao)手(shou)(shou)架(jia)根據波紋管(guan)(guan)的(de)直(zhi)徑(jing)提前確定(ding)，采(cai)用管(guan)(guan)扣(kou)連接鋼管(guan)(guan)的(de)方式搭(da)設(she)腳(jiao)手(shou)(shou)架(jia)，形式分A型(xing)和B型(xing)腳(jiao)手(shou)(shou)架(jia)長度(du)一般長25m、克0、6m、高為2d3(d為波紋管(guan)(guan)直(zhi)徑(jing))，B型(xing)腳(jiao)手(shou)(shou)架(jia)一般克為25m高依據波紋管(guan)(guan)直(zhi)徑(jing)大小拼(pin)裝接縫(feng)位(wei)置確定(ding)尺寸(cun)(cun)。腳(jiao)手(shou)(shou)架(jia)按(an)上(shang)述尺寸(cun)(cun)搭(da)設(she)便于施(shi)工、

2、拼裝(zhuang)(zhuang)類(lei)型與搭接方式：拼裝(zhuang)(zhuang)以中心軸線為基準，由中心向兩端(duan)對稱進行安(an)裝(zhuang)(zhuang)，直至(zhi)兩端(duan)。1斷(duan)面(mian)(mian)(奇數斷(duan)面(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(偶(ou)數斷(duan)面(mian)(mian))、加強斷(duan)面(mian)(mian)(偶(ou)數斷(duan)管管片）

3、波(bo)紋管拼裝(zhuang)：采(cai)用(yong)刻(ke)槽法施工(gong)的(de)(de)地基，安(an)(an)裝(zhuang)吊車依據(ju)刻(ke)槽深度，依次安(an)(an)裝(zhuang)底(di)部(bu)管片。底(di)部(bu)管片安(an)(an)裝(zhuang)完成后對剩余管片進(jin)行安(an)(an)裝(zhuang)。管片安(an)(an)裝(zhuang)同平(ping)基上(shang)的(de)(de)鋼(gang)波(bo)紋管施工(gong)。

鋼波紋管

首(shou)圈(quan)(quan)(quan)波(bo)紋(wen)管(guan)(guan)(guan)圈(quan)(quan)(quan)為奇數(shu)斷面(mian)，拼裝(zhuang)時應將管(guan)(guan)(guan)片(pian)(pian)立于(yu)地上安裝(zhuang)，使(shi)(shi)(shi)用鐵(tie)鉤的(de)(de)(de)一(yi)端(duan)(duan)勾住I斷面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian))波(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)絲囗，用12噸的(de)(de)(de)吊車勾住鐵(tie)鉤的(de)(de)(de)另一(yi)端(duan)(duan)，將波(bo)紋(wen)管(guan)(guan)(guan)片(pian)(pian)立于(yu)墊(dian)(dian)層上，然后(hou)使(shi)(shi)(shi)用同樣的(de)(de)(de)辦(ban)法(fa)將第二片(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian))波(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)按圖3、21斷面(mian)所示的(de)(de)(de)搭接(jie)方式放置(zhi)，使(shi)(shi)(shi)用撬棍將管(guan)(guan)(guan)片(pian)(pian)的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)口對齊，將提前準備好的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)螺(luo)(luo)紋(wen)部涂(tu)上渢滑劑，由內冋外(wai)插(cha)入孔位；波(bo)紋(wen)管(guan)(guan)(guan)外(wai)側套上凹(ao)墊(dian)(dian)圈(quan)(quan)(quan)或凸墊(dian)(dian)圈(quan)(quan)(quan)，遇波(bo)使(shi)(shi)(shi)用凸墊(dian)(dian)圈(quan)(quan)(quan)，遇波(bo)峰使(shi)(shi)(shi)用凹(ao)墊(dian)(dian)圈(quan)(quan)(quan)墊(dian)(dian)圈(quan)(quan)(quan)外(wai)側旋上螺(luo)(luo)母(mu)，在用套筒扳(ban)(ban)手(shou)(shou)預緊螺(luo)(luo)母(mu)，然后(hou)使(shi)(shi)(shi)用電動(dong)扳(ban)(ban)手(shou)(shou)緊固螺(luo)(luo)母(mu)兩塊(kuai)板片(pian)(pian)洤全部安裝(zhuang)完畢(bi);波(bo)紋(wen)管(guan)(guan)(guan)的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)安裝(zhuang)完畢(bi)后(hou)，需(xu)采用專用注(zhu)膠槍于(yu)端(duan)(duan)部接(jie)合處、緊回件連接(jie)的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)孔空(kong)隙(xi)處涂(tu)抹(mo)中(zhong)性硅酮耐候(hou)膠。緊接(jie)著按2#管(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)的(de)(de)(de)施工拼裝(zhuang)順序，拼裝(zhuang)好首(shou)圈(quan)(quan)(quan)波(bo)紋(wen)管(guan)(guan)(guan)圖36偶數(shu)、奇數(shu)斷面(mian)交替拼裝(zhuang)順序

4、加強斷面拼裝

當波紋(wen)管涵直徑較(jiao)大、填土高(gao)(gao)度較(jiao)高(gao)(gao)時，必須設置加(jia)(jia)強(qiang)管片，稱為加(jia)(jia)強(qiang)圈”，加(jia)(jia)強(qiang)斷(duan)面的(de)管片安裝工(gong)序。
