大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)(she)拼(pin)裝(zhuang)支架(jia):搭設(she)(she)腳(jiao)手(shou)(shou)(shou)架(jia)根據(ju)波紋管的(de)(de)直徑提前確定，采用管扣連(lian)接(jie)鋼管的(de)(de)方式(shi)搭設(she)(she)腳(jiao)手(shou)(shou)(shou)架(jia)，形式(shi)分(fen)A型(xing)和B型(xing)腳(jiao)手(shou)(shou)(shou)架(jia)長(chang)度(du)一般(ban)長(chang)25m、克0、6m、高(gao)為2d3(d為波紋管直徑)，B型(xing)腳(jiao)手(shou)(shou)(shou)架(jia)一般(ban)克為25m高(gao)依(yi)據(ju)波紋管直徑大(da)小(xiao)拼(pin)裝(zhuang)接(jie)縫位置(zhi)確定尺(chi)寸。腳(jiao)手(shou)(shou)(shou)架(jia)按上述尺(chi)寸搭設(she)(she)便(bian)于施工、

2、拼(pin)裝類型(xing)與(yu)搭接方式：拼(pin)裝以中心軸線為(wei)基(ji)準，由中心向兩端(duan)(duan)對稱(cheng)進行安裝，直至兩端(duan)(duan)。1斷(duan)面(mian)(mian)(奇數(shu)斷(duan)面(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(偶數(shu)斷(duan)面(mian)(mian))、加強斷(duan)面(mian)(mian)(偶數(shu)斷(duan)管管片）

3、波紋(wen)管(guan)拼裝(zhuang)：采用刻槽法施工的地基，安裝(zhuang)吊車依據刻槽深度，依次安裝(zhuang)底部管(guan)片。底部管(guan)片安裝(zhuang)完成后對剩余管(guan)片進行安裝(zhuang)。管(guan)片安裝(zhuang)同平(ping)基上的鋼波紋(wen)管(guan)施工。

首圈(quan)(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)圈(quan)(quan)為(wei)奇(qi)數(shu)(shu)斷面，拼(pin)裝時應將(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于(yu)地上(shang)安(an)裝，使(shi)用(yong)鐵鉤的一端勾住(zhu)I斷面片(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)絲囗，用(yong)12噸的吊車勾住(zhu)鐵鉤的另一端，將(jiang)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于(yu)墊(dian)(dian)(dian)層上(shang)，然后(hou)使(shi)用(yong)同樣的辦(ban)法(fa)將(jiang)第二片(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)按圖3、21斷面所示的搭接(jie)方(fang)式放置，使(shi)用(yong)撬棍將(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的螺(luo)栓口對齊，將(jiang)提(ti)前準備好(hao)(hao)的螺(luo)栓螺(luo)紋(wen)(wen)(wen)部涂(tu)(tu)上(shang)渢滑劑，由內冋外插入(ru)孔(kong)位(wei)；波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)外側套(tao)上(shang)凹墊(dian)(dian)(dian)圈(quan)(quan)或凸墊(dian)(dian)(dian)圈(quan)(quan)，遇(yu)波(bo)使(shi)用(yong)凸墊(dian)(dian)(dian)圈(quan)(quan)，遇(yu)波(bo)峰使(shi)用(yong)凹墊(dian)(dian)(dian)圈(quan)(quan)墊(dian)(dian)(dian)圈(quan)(quan)外側旋上(shang)螺(luo)母(mu)，在用(yong)套(tao)筒扳手預緊(jin)螺(luo)母(mu)，然后(hou)使(shi)用(yong)電動扳手緊(jin)固螺(luo)母(mu)兩(liang)塊(kuai)板片(pian)(pian)(pian)洤全(quan)部安(an)裝完畢(bi);波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)的螺(luo)栓安(an)裝完畢(bi)后(hou)，需(xu)采用(yong)專用(yong)注膠槍于(yu)端部接(jie)合處、緊(jin)回件連接(jie)的螺(luo)栓孔(kong)空隙處涂(tu)(tu)抹(mo)中(zhong)性硅酮(tong)耐候(hou)膠。緊(jin)接(jie)著按2#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的施工拼(pin)裝順(shun)序(xu)，拼(pin)裝好(hao)(hao)首圈(quan)(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)圖36偶數(shu)(shu)、奇(qi)數(shu)(shu)斷面交替拼(pin)裝順(shun)序(xu)

4、加強斷面拼裝

當波紋管涵直徑(jing)較(jiao)大、填土(tu)高(gao)度較(jiao)高(gao)時，必(bi)須設(she)置加強管片(pian)，稱為加強圈”，加強斷面的管片(pian)安裝工序。
