大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝支架(jia):搭(da)設(she)腳手(shou)(shou)架(jia)根據波紋管的直(zhi)(zhi)徑(jing)提前確定，采用(yong)管扣連接(jie)鋼管的方式搭(da)設(she)腳手(shou)(shou)架(jia)，形式分A型和B型腳手(shou)(shou)架(jia)長度一般長25m、克0、6m、高(gao)為2d3(d為波紋管直(zhi)(zhi)徑(jing))，B型腳手(shou)(shou)架(jia)一般克為25m高(gao)依據波紋管直(zhi)(zhi)徑(jing)大小拼裝接(jie)縫位(wei)置確定尺(chi)寸。腳手(shou)(shou)架(jia)按(an)上述尺(chi)寸搭(da)設(she)便于施(shi)工、

2、拼裝(zhuang)類型與搭接方式：拼裝(zhuang)以中心軸線(xian)為基準，由中心向(xiang)兩(liang)端(duan)對稱(cheng)進行(xing)安裝(zhuang)，直至(zhi)兩(liang)端(duan)。1斷(duan)面(mian)(mian)(mian)(奇數(shu)(shu)斷(duan)面(mian)(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(mian)(偶數(shu)(shu)斷(duan)面(mian)(mian)(mian))、加強斷(duan)面(mian)(mian)(mian)(偶數(shu)(shu)斷(duan)管(guan)管(guan)片）

3、波紋(wen)(wen)管(guan)(guan)(guan)拼裝(zhuang)：采用刻(ke)槽(cao)法施工(gong)的地(di)基，安裝(zhuang)吊(diao)車依據刻(ke)槽(cao)深(shen)度(du)，依次安裝(zhuang)底(di)(di)部(bu)管(guan)(guan)(guan)片(pian)。底(di)(di)部(bu)管(guan)(guan)(guan)片(pian)安裝(zhuang)完成后對(dui)剩余管(guan)(guan)(guan)片(pian)進(jin)行安裝(zhuang)。管(guan)(guan)(guan)片(pian)安裝(zhuang)同平基上的鋼波紋(wen)(wen)管(guan)(guan)(guan)施工(gong)。

首圈(quan)(quan)(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)圈(quan)(quan)(quan)為奇(qi)數斷面，拼(pin)裝(zhuang)(zhuang)時(shi)應將(jiang)(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于(yu)地上(shang)安裝(zhuang)(zhuang)，使(shi)(shi)(shi)用(yong)(yong)鐵(tie)鉤的(de)(de)(de)(de)一(yi)端(duan)勾住I斷面片(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)(luo)絲(si)囗，用(yong)(yong)12噸的(de)(de)(de)(de)吊(diao)車(che)勾住鐵(tie)鉤的(de)(de)(de)(de)另一(yi)端(duan)，將(jiang)(jiang)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于(yu)墊(dian)層上(shang)，然后使(shi)(shi)(shi)用(yong)(yong)同樣的(de)(de)(de)(de)辦法將(jiang)(jiang)第(di)二片(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)按圖3、21斷面所示的(de)(de)(de)(de)搭接方式放置(zhi)，使(shi)(shi)(shi)用(yong)(yong)撬(qiao)棍將(jiang)(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)口對齊，將(jiang)(jiang)提前準備好的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋(wen)(wen)部(bu)涂上(shang)渢滑劑，由(you)內冋外插入孔(kong)(kong)位；波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)外側套(tao)上(shang)凹(ao)墊(dian)圈(quan)(quan)(quan)或凸墊(dian)圈(quan)(quan)(quan)，遇波(bo)使(shi)(shi)(shi)用(yong)(yong)凸墊(dian)圈(quan)(quan)(quan)，遇波(bo)峰使(shi)(shi)(shi)用(yong)(yong)凹(ao)墊(dian)圈(quan)(quan)(quan)墊(dian)圈(quan)(quan)(quan)外側旋上(shang)螺(luo)(luo)(luo)母(mu)，在用(yong)(yong)套(tao)筒扳(ban)手預(yu)緊(jin)(jin)螺(luo)(luo)(luo)母(mu)，然后使(shi)(shi)(shi)用(yong)(yong)電動扳(ban)手緊(jin)(jin)固螺(luo)(luo)(luo)母(mu)兩塊板片(pian)(pian)(pian)洤(quan)全部(bu)安裝(zhuang)(zhuang)完(wan)畢;波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)安裝(zhuang)(zhuang)完(wan)畢后，需采用(yong)(yong)專用(yong)(yong)注膠槍于(yu)端(duan)部(bu)接合處、緊(jin)(jin)回件連接的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)孔(kong)(kong)空隙處涂抹(mo)中(zhong)性(xing)硅(gui)酮耐候膠。緊(jin)(jin)接著(zhu)按2#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)(de)施工(gong)拼(pin)裝(zhuang)(zhuang)順序，拼(pin)裝(zhuang)(zhuang)好首圈(quan)(quan)(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)圖36偶數、奇(qi)數斷面交替拼(pin)裝(zhuang)(zhuang)順序

4、加強斷面拼裝

當波紋管(guan)(guan)涵直徑較(jiao)大、填土高(gao)度(du)較(jiao)高(gao)時(shi)，必須設(she)置加強(qiang)管(guan)(guan)片，稱為加強(qiang)圈”，加強(qiang)斷面(mian)的管(guan)(guan)片安(an)裝工序。
