大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼(pin)裝支架(jia)(jia):搭設(she)腳(jiao)手(shou)(shou)(shou)架(jia)(jia)根據波(bo)紋管的(de)直徑提前確定，采用管扣連接(jie)鋼管的(de)方式(shi)搭設(she)腳(jiao)手(shou)(shou)(shou)架(jia)(jia)，形(xing)式(shi)分A型(xing)和(he)B型(xing)腳(jiao)手(shou)(shou)(shou)架(jia)(jia)長度一般長25m、克(ke)0、6m、高為2d3(d為波(bo)紋管直徑)，B型(xing)腳(jiao)手(shou)(shou)(shou)架(jia)(jia)一般克(ke)為25m高依(yi)據波(bo)紋管直徑大(da)小拼(pin)裝接(jie)縫位置確定尺寸。腳(jiao)手(shou)(shou)(shou)架(jia)(jia)按上述尺寸搭設(she)便(bian)于施工、

2、拼裝(zhuang)類(lei)型與搭接方式(shi)：拼裝(zhuang)以中心(xin)軸線為基準，由中心(xin)向兩端對稱進(jin)行(xing)安裝(zhuang)，直(zhi)至(zhi)兩端。1斷(duan)面(mian)(奇數(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數(shu)斷(duan)面(mian))、加強斷(duan)面(mian)(偶數(shu)斷(duan)管(guan)(guan)管(guan)(guan)片）

3、波(bo)紋管拼裝(zhuang)(zhuang)(zhuang)：采用刻槽法施工的(de)地基，安(an)裝(zhuang)(zhuang)(zhuang)吊車依(yi)據刻槽深度(du)，依(yi)次(ci)安(an)裝(zhuang)(zhuang)(zhuang)底(di)部(bu)管片。底(di)部(bu)管片安(an)裝(zhuang)(zhuang)(zhuang)完成后對(dui)剩余(yu)管片進(jin)行安(an)裝(zhuang)(zhuang)(zhuang)。管片安(an)裝(zhuang)(zhuang)(zhuang)同(tong)平基上的(de)鋼波(bo)紋管施工。

首(shou)圈波(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)(guan)圈為奇數斷面(mian)，拼裝(zhuang)時應將管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)地上(shang)(shang)安裝(zhuang)，使(shi)用(yong)鐵(tie)鉤的(de)(de)(de)一端(duan)(duan)勾住I斷面(mian)片(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)絲囗，用(yong)12噸的(de)(de)(de)吊車勾住鐵(tie)鉤的(de)(de)(de)另一端(duan)(duan)，將波(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)墊(dian)層上(shang)(shang)，然(ran)后使(shi)用(yong)同樣的(de)(de)(de)辦(ban)法將第(di)二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)按圖(tu)3、21斷面(mian)所示(shi)的(de)(de)(de)搭接方式放置(zhi)，使(shi)用(yong)撬棍(gun)將管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)螺(luo)栓(shuan)口對齊，將提前準備好(hao)的(de)(de)(de)螺(luo)栓(shuan)螺(luo)紋(wen)(wen)(wen)(wen)(wen)部(bu)涂(tu)上(shang)(shang)渢滑劑，由(you)內冋外(wai)(wai)插入(ru)孔(kong)位(wei)；波(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)(guan)外(wai)(wai)側套上(shang)(shang)凹墊(dian)圈或凸墊(dian)圈，遇(yu)波(bo)使(shi)用(yong)凸墊(dian)圈，遇(yu)波(bo)峰(feng)使(shi)用(yong)凹墊(dian)圈墊(dian)圈外(wai)(wai)側旋上(shang)(shang)螺(luo)母，在用(yong)套筒扳(ban)(ban)手(shou)預緊螺(luo)母，然(ran)后使(shi)用(yong)電(dian)動扳(ban)(ban)手(shou)緊固螺(luo)母兩(liang)塊板片(pian)(pian)(pian)(pian)洤全部(bu)安裝(zhuang)完畢(bi);波(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)(guan)的(de)(de)(de)螺(luo)栓(shuan)安裝(zhuang)完畢(bi)后，需采(cai)用(yong)專用(yong)注膠(jiao)槍于(yu)端(duan)(duan)部(bu)接合處、緊回件(jian)連接的(de)(de)(de)螺(luo)栓(shuan)孔(kong)空(kong)隙處涂(tu)抹(mo)中性硅酮耐(nai)候膠(jiao)。緊接著按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)(de)施工拼裝(zhuang)順(shun)序(xu)，拼裝(zhuang)好(hao)首(shou)圈波(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)(guan)圖(tu)36偶數、奇數斷面(mian)交替拼裝(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當波(bo)紋(wen)管涵直徑較大、填土高度較高時，必須設(she)置加(jia)強管片，稱為加(jia)強圈”，加(jia)強斷面的管片安(an)裝工序。
