大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)(she)(she)拼(pin)裝支架(jia):搭(da)設(she)(she)(she)腳(jiao)手(shou)(shou)(shou)架(jia)根據波紋管(guan)(guan)的直徑提前確(que)定，采用(yong)管(guan)(guan)扣連(lian)接鋼管(guan)(guan)的方式(shi)搭(da)設(she)(she)(she)腳(jiao)手(shou)(shou)(shou)架(jia)，形式(shi)分A型(xing)(xing)和(he)B型(xing)(xing)腳(jiao)手(shou)(shou)(shou)架(jia)長度一(yi)般長25m、克0、6m、高為(wei)2d3(d為(wei)波紋管(guan)(guan)直徑)，B型(xing)(xing)腳(jiao)手(shou)(shou)(shou)架(jia)一(yi)般克為(wei)25m高依據波紋管(guan)(guan)直徑大(da)小拼(pin)裝接縫位置確(que)定尺寸。腳(jiao)手(shou)(shou)(shou)架(jia)按上(shang)述尺寸搭(da)設(she)(she)(she)便于(yu)施(shi)工(gong)、

2、拼裝(zhuang)類型與搭接方式：拼裝(zhuang)以中心(xin)軸線為(wei)基準，由中心(xin)向(xiang)兩端(duan)對稱(cheng)進(jin)行安(an)裝(zhuang)，直至兩端(duan)。1斷(duan)(duan)面(mian)(mian)(mian)(奇數(shu)斷(duan)(duan)面(mian)(mian)(mian))、Ⅱ斷(duan)(duan)面(mian)(mian)(mian)(偶數(shu)斷(duan)(duan)面(mian)(mian)(mian))、加強斷(duan)(duan)面(mian)(mian)(mian)(偶數(shu)斷(duan)(duan)管管片(pian)）

3、波(bo)紋(wen)(wen)管拼裝(zhuang)(zhuang)：采用刻槽(cao)法施(shi)(shi)工(gong)的地基，安裝(zhuang)(zhuang)吊(diao)車依(yi)據刻槽(cao)深度，依(yi)次安裝(zhuang)(zhuang)底部管片(pian)(pian)(pian)。底部管片(pian)(pian)(pian)安裝(zhuang)(zhuang)完(wan)成(cheng)后對剩(sheng)余(yu)管片(pian)(pian)(pian)進行安裝(zhuang)(zhuang)。管片(pian)(pian)(pian)安裝(zhuang)(zhuang)同平基上的鋼波(bo)紋(wen)(wen)管施(shi)(shi)工(gong)。

首圈(quan)波(bo)紋(wen)(wen)管(guan)(guan)圈(quan)為奇(qi)數(shu)斷(duan)面，拼裝時應(ying)將(jiang)管(guan)(guan)片(pian)(pian)(pian)立于地上(shang)(shang)安(an)裝，使(shi)(shi)用(yong)(yong)鐵鉤的(de)一端勾(gou)(gou)住I斷(duan)面片(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)12噸的(de)吊車(che)勾(gou)(gou)住鐵鉤的(de)另一端，將(jiang)波(bo)紋(wen)(wen)管(guan)(guan)片(pian)(pian)(pian)立于墊(dian)層上(shang)(shang)，然后(hou)(hou)使(shi)(shi)用(yong)(yong)同樣的(de)辦(ban)法(fa)將(jiang)第二片(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)按圖3、21斷(duan)面所(suo)示的(de)搭接方式放置，使(shi)(shi)用(yong)(yong)撬棍將(jiang)管(guan)(guan)片(pian)(pian)(pian)的(de)螺(luo)(luo)栓(shuan)(shuan)口對齊，將(jiang)提前(qian)準備好(hao)的(de)螺(luo)(luo)栓(shuan)(shuan)螺(luo)(luo)紋(wen)(wen)部涂上(shang)(shang)渢滑劑，由內冋外插入孔(kong)位；波(bo)紋(wen)(wen)管(guan)(guan)外側套(tao)(tao)上(shang)(shang)凹墊(dian)圈(quan)或凸墊(dian)圈(quan)，遇波(bo)使(shi)(shi)用(yong)(yong)凸墊(dian)圈(quan)，遇波(bo)峰使(shi)(shi)用(yong)(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外側旋(xuan)上(shang)(shang)螺(luo)(luo)母(mu)(mu)，在用(yong)(yong)套(tao)(tao)筒扳(ban)手預緊(jin)(jin)(jin)螺(luo)(luo)母(mu)(mu)，然后(hou)(hou)使(shi)(shi)用(yong)(yong)電(dian)動扳(ban)手緊(jin)(jin)(jin)固螺(luo)(luo)母(mu)(mu)兩塊板片(pian)(pian)(pian)洤全部安(an)裝完畢;波(bo)紋(wen)(wen)管(guan)(guan)的(de)螺(luo)(luo)栓(shuan)(shuan)安(an)裝完畢后(hou)(hou)，需采用(yong)(yong)專用(yong)(yong)注膠(jiao)槍于端部接合處、緊(jin)(jin)(jin)回件連接的(de)螺(luo)(luo)栓(shuan)(shuan)孔(kong)空隙處涂抹中性硅酮耐候膠(jiao)。緊(jin)(jin)(jin)接著按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)施工拼裝順序，拼裝好(hao)首圈(quan)波(bo)紋(wen)(wen)管(guan)(guan)圖36偶數(shu)、奇(qi)數(shu)斷(duan)面交替拼裝順序

4、加強斷面拼裝

當波紋(wen)管(guan)涵(han)直徑較(jiao)(jiao)大、填土高(gao)度較(jiao)(jiao)高(gao)時(shi)，必須設置加(jia)強管(guan)片(pian)，稱為加(jia)強圈”，加(jia)強斷面(mian)的管(guan)片(pian)安裝工序。
