大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝(zhuang)(zhuang)支架(jia)(jia):搭(da)設(she)腳手(shou)架(jia)(jia)根據(ju)波(bo)(bo)紋(wen)管(guan)(guan)的直(zhi)徑(jing)提前確定，采用管(guan)(guan)扣連接鋼管(guan)(guan)的方式(shi)搭(da)設(she)腳手(shou)架(jia)(jia)，形式(shi)分A型和B型腳手(shou)架(jia)(jia)長(chang)度一般長(chang)25m、克(ke)0、6m、高(gao)(gao)為(wei)2d3(d為(wei)波(bo)(bo)紋(wen)管(guan)(guan)直(zhi)徑(jing))，B型腳手(shou)架(jia)(jia)一般克(ke)為(wei)25m高(gao)(gao)依據(ju)波(bo)(bo)紋(wen)管(guan)(guan)直(zhi)徑(jing)大小拼裝(zhuang)(zhuang)接縫位置確定尺寸。腳手(shou)架(jia)(jia)按上述尺寸搭(da)設(she)便于(yu)施(shi)工、

2、拼裝(zhuang)類(lei)型與搭接方式：拼裝(zhuang)以中心(xin)軸線(xian)為(wei)基準，由(you)中心(xin)向(xiang)兩端(duan)對(dui)稱進(jin)行安裝(zhuang)，直至(zhi)兩端(duan)。1斷(duan)(duan)面(mian)(mian)(奇數斷(duan)(duan)面(mian)(mian))、Ⅱ斷(duan)(duan)面(mian)(mian)(偶(ou)數斷(duan)(duan)面(mian)(mian))、加強(qiang)斷(duan)(duan)面(mian)(mian)(偶(ou)數斷(duan)(duan)管(guan)管(guan)片(pian)）

3、波紋管拼裝(zhuang)：采用(yong)刻(ke)槽法施(shi)(shi)工(gong)的(de)地基，安裝(zhuang)吊車依(yi)(yi)據刻(ke)槽深度(du)，依(yi)(yi)次(ci)安裝(zhuang)底部(bu)管片。底部(bu)管片安裝(zhuang)完成后(hou)對剩(sheng)余管片進(jin)行安裝(zhuang)。管片安裝(zhuang)同平基上的(de)鋼波紋管施(shi)(shi)工(gong)。

首(shou)圈(quan)波(bo)(bo)(bo)紋(wen)管(guan)(guan)圈(quan)為奇(qi)數斷(duan)面，拼(pin)裝(zhuang)時應(ying)將(jiang)管(guan)(guan)片(pian)(pian)立于(yu)地上(shang)(shang)安裝(zhuang)，使用(yong)(yong)鐵鉤(gou)的(de)(de)一端勾(gou)(gou)住(zhu)(zhu)I斷(duan)面片(pian)(pian)(1#管(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)12噸(dun)的(de)(de)吊車勾(gou)(gou)住(zhu)(zhu)鐵鉤(gou)的(de)(de)另一端，將(jiang)波(bo)(bo)(bo)紋(wen)管(guan)(guan)片(pian)(pian)立于(yu)墊層(ceng)上(shang)(shang)，然后使用(yong)(yong)同樣的(de)(de)辦法將(jiang)第二片(pian)(pian)(6#管(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)按(an)圖(tu)(tu)3、21斷(duan)面所示的(de)(de)搭接(jie)方(fang)式放置，使用(yong)(yong)撬棍將(jiang)管(guan)(guan)片(pian)(pian)的(de)(de)螺(luo)(luo)栓(shuan)(shuan)口對齊，將(jiang)提前(qian)準(zhun)備(bei)好(hao)的(de)(de)螺(luo)(luo)栓(shuan)(shuan)螺(luo)(luo)紋(wen)部涂上(shang)(shang)渢滑劑，由內(nei)冋外插(cha)入孔(kong)(kong)位(wei)；波(bo)(bo)(bo)紋(wen)管(guan)(guan)外側(ce)套(tao)上(shang)(shang)凹墊圈(quan)或凸墊圈(quan)，遇波(bo)(bo)(bo)使用(yong)(yong)凸墊圈(quan)，遇波(bo)(bo)(bo)峰使用(yong)(yong)凹墊圈(quan)墊圈(quan)外側(ce)旋上(shang)(shang)螺(luo)(luo)母(mu)，在用(yong)(yong)套(tao)筒扳(ban)手預(yu)緊螺(luo)(luo)母(mu)，然后使用(yong)(yong)電動(dong)扳(ban)手緊固(gu)螺(luo)(luo)母(mu)兩塊板(ban)片(pian)(pian)洤(quan)全部安裝(zhuang)完畢;波(bo)(bo)(bo)紋(wen)管(guan)(guan)的(de)(de)螺(luo)(luo)栓(shuan)(shuan)安裝(zhuang)完畢后，需采用(yong)(yong)專用(yong)(yong)注膠槍于(yu)端部接(jie)合處(chu)、緊回件(jian)連接(jie)的(de)(de)螺(luo)(luo)栓(shuan)(shuan)孔(kong)(kong)空隙處(chu)涂抹中性(xing)硅酮(tong)耐(nai)候膠。緊接(jie)著按(an)2#管(guan)(guan)片(pian)(pian)、5#管(guan)(guan)片(pian)(pian)、3#管(guan)(guan)片(pian)(pian)、4#管(guan)(guan)片(pian)(pian)的(de)(de)施工拼(pin)裝(zhuang)順序，拼(pin)裝(zhuang)好(hao)首(shou)圈(quan)波(bo)(bo)(bo)紋(wen)管(guan)(guan)圖(tu)(tu)36偶數、奇(qi)數斷(duan)面交替拼(pin)裝(zhuang)順序

4、加強斷面拼裝

當波紋管(guan)涵(han)直徑較大、填土(tu)高(gao)度較高(gao)時，必須設置加強管(guan)片(pian)(pian)，稱為(wei)加強圈(quan)”，加強斷面的管(guan)片(pian)(pian)安裝(zhuang)工序。
