大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝支架(jia):搭設(she)腳(jiao)手(shou)(shou)(shou)架(jia)根據(ju)波(bo)紋(wen)管的(de)直徑提前確(que)定，采用管扣(kou)連(lian)接(jie)鋼管的(de)方式搭設(she)腳(jiao)手(shou)(shou)(shou)架(jia)，形(xing)式分(fen)A型和B型腳(jiao)手(shou)(shou)(shou)架(jia)長度一般(ban)長25m、克0、6m、高(gao)為2d3(d為波(bo)紋(wen)管直徑)，B型腳(jiao)手(shou)(shou)(shou)架(jia)一般(ban)克為25m高(gao)依(yi)據(ju)波(bo)紋(wen)管直徑大小(xiao)拼裝接(jie)縫位置(zhi)確(que)定尺(chi)寸。腳(jiao)手(shou)(shou)(shou)架(jia)按(an)上述尺(chi)寸搭設(she)便于(yu)施工、

2、拼(pin)裝(zhuang)類型與搭接方式：拼(pin)裝(zhuang)以中(zhong)心軸線為基準，由(you)中(zhong)心向兩(liang)端對(dui)稱進行安裝(zhuang)，直至兩(liang)端。1斷(duan)面(mian)(mian)(mian)(奇數(shu)斷(duan)面(mian)(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(mian)(偶數(shu)斷(duan)面(mian)(mian)(mian))、加強斷(duan)面(mian)(mian)(mian)(偶數(shu)斷(duan)管管片）

3、波紋(wen)(wen)管拼裝(zhuang)：采用刻槽(cao)法(fa)施(shi)工的地基(ji)，安裝(zhuang)吊車依據刻槽(cao)深度(du)，依次安裝(zhuang)底(di)部管片。底(di)部管片安裝(zhuang)完(wan)成后對剩余管片進行安裝(zhuang)。管片安裝(zhuang)同平(ping)基(ji)上的鋼波紋(wen)(wen)管施(shi)工。

首(shou)圈波(bo)(bo)紋(wen)管(guan)(guan)(guan)圈為奇數(shu)斷(duan)面，拼(pin)裝時應(ying)將管(guan)(guan)(guan)片(pian)(pian)(pian)立于(yu)地上(shang)安(an)裝，使用(yong)(yong)(yong)鐵鉤的(de)(de)一端勾住(zhu)I斷(duan)面片(pian)(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)螺絲囗(wei)，用(yong)(yong)(yong)12噸的(de)(de)吊車勾住(zhu)鐵鉤的(de)(de)另一端，將波(bo)(bo)紋(wen)管(guan)(guan)(guan)片(pian)(pian)(pian)立于(yu)墊(dian)層上(shang)，然(ran)后(hou)使用(yong)(yong)(yong)同(tong)樣的(de)(de)辦(ban)法(fa)將第二片(pian)(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)按圖3、21斷(duan)面所示的(de)(de)搭接(jie)方式放置，使用(yong)(yong)(yong)撬棍將管(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)螺栓口(kou)對齊，將提(ti)前(qian)準備好的(de)(de)螺栓螺紋(wen)部(bu)涂上(shang)渢(feng)滑劑(ji)，由內冋外(wai)插入孔(kong)(kong)位(wei)；波(bo)(bo)紋(wen)管(guan)(guan)(guan)外(wai)側套(tao)上(shang)凹(ao)(ao)墊(dian)圈或凸墊(dian)圈，遇(yu)波(bo)(bo)使用(yong)(yong)(yong)凸墊(dian)圈，遇(yu)波(bo)(bo)峰(feng)使用(yong)(yong)(yong)凹(ao)(ao)墊(dian)圈墊(dian)圈外(wai)側旋上(shang)螺母，在用(yong)(yong)(yong)套(tao)筒扳手(shou)預緊螺母，然(ran)后(hou)使用(yong)(yong)(yong)電動扳手(shou)緊固(gu)螺母兩塊板片(pian)(pian)(pian)洤全(quan)部(bu)安(an)裝完畢;波(bo)(bo)紋(wen)管(guan)(guan)(guan)的(de)(de)螺栓安(an)裝完畢后(hou)，需采用(yong)(yong)(yong)專用(yong)(yong)(yong)注(zhu)膠槍于(yu)端部(bu)接(jie)合處(chu)、緊回件連接(jie)的(de)(de)螺栓孔(kong)(kong)空隙處(chu)涂抹中性硅酮耐候膠。緊接(jie)著按2#管(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)施(shi)工拼(pin)裝順(shun)序，拼(pin)裝好首(shou)圈波(bo)(bo)紋(wen)管(guan)(guan)(guan)圖36偶數(shu)、奇數(shu)斷(duan)面交替拼(pin)裝順(shun)序

4、加強斷面拼裝

當波(bo)紋管(guan)涵直徑較(jiao)大、填土(tu)高度(du)較(jiao)高時，必須(xu)設(she)置(zhi)加(jia)強管(guan)片，稱為(wei)加(jia)強圈”，加(jia)強斷面的(de)管(guan)片安裝(zhuang)工序。
