大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼(pin)裝支架(jia):搭(da)設腳(jiao)(jiao)手架(jia)根據(ju)波紋管(guan)(guan)(guan)的(de)直(zhi)徑提前確定，采(cai)用管(guan)(guan)(guan)扣連接鋼管(guan)(guan)(guan)的(de)方(fang)式搭(da)設腳(jiao)(jiao)手架(jia)，形式分(fen)A型和B型腳(jiao)(jiao)手架(jia)長(chang)度一(yi)般(ban)長(chang)25m、克(ke)0、6m、高為2d3(d為波紋管(guan)(guan)(guan)直(zhi)徑)，B型腳(jiao)(jiao)手架(jia)一(yi)般(ban)克(ke)為25m高依據(ju)波紋管(guan)(guan)(guan)直(zhi)徑大小(xiao)拼(pin)裝接縫(feng)位置確定尺寸。腳(jiao)(jiao)手架(jia)按上述尺寸搭(da)設便于(yu)施工、

2、拼裝類型與搭接方(fang)式(shi)：拼裝以中(zhong)(zhong)心(xin)(xin)軸線為基(ji)準，由中(zhong)(zhong)心(xin)(xin)向兩(liang)端對稱進行(xing)安裝，直至(zhi)兩(liang)端。1斷(duan)面(mian)(奇數(shu)(shu)(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數(shu)(shu)(shu)斷(duan)面(mian))、加強斷(duan)面(mian)(偶數(shu)(shu)(shu)斷(duan)管(guan)管(guan)片）

3、波紋管拼裝(zhuang)：采用刻(ke)槽(cao)法施工(gong)的地基，安(an)裝(zhuang)吊車依(yi)(yi)據(ju)刻(ke)槽(cao)深度，依(yi)(yi)次(ci)安(an)裝(zhuang)底(di)部管片(pian)(pian)。底(di)部管片(pian)(pian)安(an)裝(zhuang)完成(cheng)后(hou)對剩余管片(pian)(pian)進行(xing)安(an)裝(zhuang)。管片(pian)(pian)安(an)裝(zhuang)同平基上的鋼波紋管施工(gong)。

首圈(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)圈(quan)為奇(qi)(qi)數斷(duan)面(mian)(mian)，拼(pin)裝(zhuang)時應將(jiang)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)地(di)上(shang)(shang)安(an)裝(zhuang)，使(shi)用鐵(tie)鉤的(de)(de)一端(duan)勾(gou)住(zhu)I斷(duan)面(mian)(mian)片(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)(luo)(luo)絲囗，用12噸的(de)(de)吊車勾(gou)住(zhu)鐵(tie)鉤的(de)(de)另一端(duan)，將(jiang)波(bo)(bo)紋(wen)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)墊層上(shang)(shang)，然(ran)后(hou)使(shi)用同(tong)樣(yang)的(de)(de)辦(ban)法(fa)將(jiang)第二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)按圖(tu)3、21斷(duan)面(mian)(mian)所示的(de)(de)搭接方式放(fang)置，使(shi)用撬棍將(jiang)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)螺(luo)(luo)(luo)(luo)栓口對齊，將(jiang)提(ti)前準備好(hao)的(de)(de)螺(luo)(luo)(luo)(luo)栓螺(luo)(luo)(luo)(luo)紋(wen)部涂上(shang)(shang)渢滑劑，由內冋外(wai)插入孔位；波(bo)(bo)紋(wen)管(guan)(guan)(guan)外(wai)側套(tao)上(shang)(shang)凹墊圈(quan)或(huo)凸(tu)墊圈(quan)，遇(yu)(yu)波(bo)(bo)使(shi)用凸(tu)墊圈(quan)，遇(yu)(yu)波(bo)(bo)峰(feng)使(shi)用凹墊圈(quan)墊圈(quan)外(wai)側旋上(shang)(shang)螺(luo)(luo)(luo)(luo)母，在用套(tao)筒扳手(shou)預(yu)緊(jin)(jin)螺(luo)(luo)(luo)(luo)母，然(ran)后(hou)使(shi)用電動扳手(shou)緊(jin)(jin)固(gu)螺(luo)(luo)(luo)(luo)母兩塊板片(pian)(pian)(pian)(pian)洤全部安(an)裝(zhuang)完(wan)畢;波(bo)(bo)紋(wen)管(guan)(guan)(guan)的(de)(de)螺(luo)(luo)(luo)(luo)栓安(an)裝(zhuang)完(wan)畢后(hou)，需采用專用注膠槍于(yu)端(duan)部接合處、緊(jin)(jin)回件連(lian)接的(de)(de)螺(luo)(luo)(luo)(luo)栓孔空隙(xi)處涂抹(mo)中性(xing)硅(gui)酮耐候(hou)膠。緊(jin)(jin)接著按2#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)施工拼(pin)裝(zhuang)順序，拼(pin)裝(zhuang)好(hao)首圈(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)圖(tu)36偶數、奇(qi)(qi)數斷(duan)面(mian)(mian)交替拼(pin)裝(zhuang)順序

4、加強斷面拼裝

當波紋(wen)管(guan)涵直徑較大(da)、填土高度較高時(shi)，必(bi)須(xu)設(she)置加強管(guan)片(pian)，稱(cheng)為加強圈”，加強斷面的管(guan)片(pian)安裝工序。
