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)(jiao)手(shou)(shou)架(jia)根據(ju)波紋管(guan)的直(zhi)(zhi)徑(jing)提前確(que)定，采用(yong)管(guan)扣連接鋼管(guan)的方式搭(da)設(she)腳(jiao)(jiao)手(shou)(shou)架(jia)，形式分(fen)A型(xing)和B型(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)長(chang)度一般長(chang)25m、克0、6m、高(gao)為(wei)2d3(d為(wei)波紋管(guan)直(zhi)(zhi)徑(jing))，B型(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)一般克為(wei)25m高(gao)依(yi)據(ju)波紋管(guan)直(zhi)(zhi)徑(jing)大小(xiao)拼(pin)裝接縫(feng)位置確(que)定尺寸。腳(jiao)(jiao)手(shou)(shou)架(jia)按(an)上述尺寸搭(da)設(she)便(bian)于施工、

2、拼裝(zhuang)類型與(yu)搭接(jie)方式：拼裝(zhuang)以中(zhong)心軸線為基準，由中(zhong)心向兩端(duan)對稱進(jin)行安(an)裝(zhuang)，直(zhi)至兩端(duan)。1斷(duan)面(奇數(shu)斷(duan)面)、Ⅱ斷(duan)面(偶(ou)數(shu)斷(duan)面)、加(jia)強斷(duan)面(偶(ou)數(shu)斷(duan)管(guan)(guan)管(guan)(guan)片）

3、波紋管(guan)拼裝(zhuang)(zhuang)：采用刻槽法施工(gong)的地(di)基，安(an)裝(zhuang)(zhuang)吊車依據刻槽深度，依次安(an)裝(zhuang)(zhuang)底部管(guan)片。底部管(guan)片安(an)裝(zhuang)(zhuang)完(wan)成后對剩余管(guan)片進行安(an)裝(zhuang)(zhuang)。管(guan)片安(an)裝(zhuang)(zhuang)同平基上的鋼波紋管(guan)施工(gong)。

鋼波紋管

首(shou)圈(quan)波(bo)(bo)紋(wen)管(guan)(guan)圈(quan)為(wei)奇數(shu)斷面(mian)(mian)，拼(pin)裝時應將(jiang)管(guan)(guan)片(pian)(pian)立(li)于(yu)地上安(an)裝，使(shi)(shi)用(yong)鐵鉤(gou)的(de)(de)一端勾(gou)住I斷面(mian)(mian)片(pian)(pian)(1#管(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)螺(luo)(luo)(luo)絲囗，用(yong)12噸的(de)(de)吊車勾(gou)住鐵鉤(gou)的(de)(de)另一端，將(jiang)波(bo)(bo)紋(wen)管(guan)(guan)片(pian)(pian)立(li)于(yu)墊(dian)層(ceng)上，然后(hou)(hou)使(shi)(shi)用(yong)同樣的(de)(de)辦(ban)法將(jiang)第二片(pian)(pian)(6#管(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)按(an)圖(tu)3、21斷面(mian)(mian)所(suo)示的(de)(de)搭接方式(shi)放(fang)置，使(shi)(shi)用(yong)撬棍將(jiang)管(guan)(guan)片(pian)(pian)的(de)(de)螺(luo)(luo)(luo)栓(shuan)(shuan)(shuan)口對齊，將(jiang)提前準備好(hao)的(de)(de)螺(luo)(luo)(luo)栓(shuan)(shuan)(shuan)螺(luo)(luo)(luo)紋(wen)部(bu)涂上渢滑劑(ji)，由內冋外(wai)插(cha)入(ru)孔位；波(bo)(bo)紋(wen)管(guan)(guan)外(wai)側套上凹(ao)墊(dian)圈(quan)或(huo)凸墊(dian)圈(quan)，遇波(bo)(bo)使(shi)(shi)用(yong)凸墊(dian)圈(quan)，遇波(bo)(bo)峰使(shi)(shi)用(yong)凹(ao)墊(dian)圈(quan)墊(dian)圈(quan)外(wai)側旋(xuan)上螺(luo)(luo)(luo)母(mu)，在(zai)用(yong)套筒扳手預(yu)緊(jin)螺(luo)(luo)(luo)母(mu)，然后(hou)(hou)使(shi)(shi)用(yong)電動扳手緊(jin)固螺(luo)(luo)(luo)母(mu)兩塊板片(pian)(pian)洤全部(bu)安(an)裝完畢;波(bo)(bo)紋(wen)管(guan)(guan)的(de)(de)螺(luo)(luo)(luo)栓(shuan)(shuan)(shuan)安(an)裝完畢后(hou)(hou)，需采用(yong)專(zhuan)用(yong)注(zhu)膠槍于(yu)端部(bu)接合處、緊(jin)回件連接的(de)(de)螺(luo)(luo)(luo)栓(shuan)(shuan)(shuan)孔空隙處涂抹中性硅酮耐(nai)候膠。緊(jin)接著按(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(shi)工拼(pin)裝順序，拼(pin)裝好(hao)首(shou)圈(quan)波(bo)(bo)紋(wen)管(guan)(guan)圖(tu)36偶數(shu)、奇數(shu)斷面(mian)(mian)交(jiao)替拼(pin)裝順序

4、加強斷面拼裝

當波紋管(guan)涵直(zhi)徑較(jiao)大、填土高(gao)度(du)較(jiao)高(gao)時，必須設(she)置(zhi)加(jia)強(qiang)管(guan)片(pian)，稱為加(jia)強(qiang)圈(quan)”，加(jia)強(qiang)斷面(mian)的管(guan)片(pian)安裝工序。
