大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝支架(jia):搭設腳手(shou)架(jia)根據波(bo)紋管(guan)(guan)的直(zhi)徑(jing)提前確定(ding)，采用管(guan)(guan)扣連接鋼管(guan)(guan)的方式(shi)搭設腳手(shou)架(jia)，形(xing)式(shi)分A型(xing)和B型(xing)腳手(shou)架(jia)長(chang)度(du)一(yi)般(ban)長(chang)25m、克(ke)(ke)0、6m、高為2d3(d為波(bo)紋管(guan)(guan)直(zhi)徑(jing))，B型(xing)腳手(shou)架(jia)一(yi)般(ban)克(ke)(ke)為25m高依據波(bo)紋管(guan)(guan)直(zhi)徑(jing)大小拼裝接縫位置確定(ding)尺(chi)寸。腳手(shou)架(jia)按上述尺(chi)寸搭設便于施工、

2、拼裝(zhuang)類型與搭(da)接方式(shi)：拼裝(zhuang)以中心軸線(xian)為基準，由中心向兩端(duan)(duan)對稱進(jin)行安裝(zhuang)，直至兩端(duan)(duan)。1斷面(mian)(奇數(shu)(shu)斷面(mian))、Ⅱ斷面(mian)(偶數(shu)(shu)斷面(mian))、加強(qiang)斷面(mian)(偶數(shu)(shu)斷管管片）

3、波(bo)紋管(guan)拼裝：采用刻槽法施工的(de)地基，安(an)(an)裝吊(diao)車依(yi)據(ju)刻槽深度，依(yi)次安(an)(an)裝底(di)部(bu)管(guan)片(pian)。底(di)部(bu)管(guan)片(pian)安(an)(an)裝完成后對剩余管(guan)片(pian)進行安(an)(an)裝。管(guan)片(pian)安(an)(an)裝同(tong)平基上的(de)鋼波(bo)紋管(guan)施工。

首圈(quan)波紋(wen)(wen)管(guan)(guan)(guan)圈(quan)為奇(qi)數(shu)(shu)斷(duan)(duan)面(mian)，拼裝時應將管(guan)(guan)(guan)片(pian)(pian)立于地上(shang)(shang)安裝，使(shi)(shi)用(yong)(yong)(yong)鐵(tie)鉤的(de)(de)(de)一(yi)端(duan)勾住I斷(duan)(duan)面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian))波紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)絲(si)囗，用(yong)(yong)(yong)12噸的(de)(de)(de)吊車(che)勾住鐵(tie)鉤的(de)(de)(de)另一(yi)端(duan)，將波紋(wen)(wen)管(guan)(guan)(guan)片(pian)(pian)立于墊(dian)層上(shang)(shang)，然(ran)后使(shi)(shi)用(yong)(yong)(yong)同(tong)樣(yang)的(de)(de)(de)辦法將第二片(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian))波紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)按圖3、21斷(duan)(duan)面(mian)所(suo)示的(de)(de)(de)搭接(jie)方(fang)式放置(zhi)，使(shi)(shi)用(yong)(yong)(yong)撬(qiao)棍(gun)將管(guan)(guan)(guan)片(pian)(pian)的(de)(de)(de)螺(luo)(luo)栓(shuan)口對齊，將提前準備好(hao)的(de)(de)(de)螺(luo)(luo)栓(shuan)螺(luo)(luo)紋(wen)(wen)部涂(tu)上(shang)(shang)渢滑(hua)劑，由(you)內(nei)冋外(wai)插(cha)入孔(kong)位；波紋(wen)(wen)管(guan)(guan)(guan)外(wai)側(ce)套上(shang)(shang)凹墊(dian)圈(quan)或凸(tu)墊(dian)圈(quan)，遇波使(shi)(shi)用(yong)(yong)(yong)凸(tu)墊(dian)圈(quan)，遇波峰使(shi)(shi)用(yong)(yong)(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外(wai)側(ce)旋(xuan)上(shang)(shang)螺(luo)(luo)母(mu)，在(zai)用(yong)(yong)(yong)套筒扳手預緊螺(luo)(luo)母(mu)，然(ran)后使(shi)(shi)用(yong)(yong)(yong)電動(dong)扳手緊固螺(luo)(luo)母(mu)兩塊(kuai)板片(pian)(pian)洤全部安裝完畢(bi)(bi);波紋(wen)(wen)管(guan)(guan)(guan)的(de)(de)(de)螺(luo)(luo)栓(shuan)安裝完畢(bi)(bi)后，需采用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠(jiao)槍于端(duan)部接(jie)合處、緊回件連接(jie)的(de)(de)(de)螺(luo)(luo)栓(shuan)孔(kong)空隙處涂(tu)抹中性硅(gui)酮耐候膠(jiao)。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)施工拼裝順序，拼裝好(hao)首圈(quan)波紋(wen)(wen)管(guan)(guan)(guan)圖36偶(ou)數(shu)(shu)、奇(qi)數(shu)(shu)斷(duan)(duan)面(mian)交替(ti)拼裝順序

4、加強斷面拼裝

當波紋管涵直徑較(jiao)大、填土(tu)高(gao)度(du)較(jiao)高(gao)時，必須(xu)設置(zhi)加(jia)強(qiang)管片，稱為加(jia)強(qiang)圈”，加(jia)強(qiang)斷面(mian)的管片安裝(zhuang)工序(xu)。
