大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝(zhuang)支(zhi)架(jia):搭設腳(jiao)手(shou)架(jia)根據(ju)波紋(wen)(wen)管的直徑提前確(que)定，采用管扣(kou)連接鋼管的方式搭設腳(jiao)手(shou)架(jia)，形(xing)式分A型和B型腳(jiao)手(shou)架(jia)長度一(yi)般長25m、克0、6m、高為2d3(d為波紋(wen)(wen)管直徑)，B型腳(jiao)手(shou)架(jia)一(yi)般克為25m高依(yi)據(ju)波紋(wen)(wen)管直徑大(da)小拼(pin)裝(zhuang)接縫位(wei)置確(que)定尺(chi)寸。腳(jiao)手(shou)架(jia)按上述尺(chi)寸搭設便于施工、

2、拼裝類型(xing)與搭接方式(shi)：拼裝以中(zhong)心軸線為(wei)基準(zhun)，由中(zhong)心向兩(liang)端(duan)對稱進行(xing)安裝，直(zhi)至兩(liang)端(duan)。1斷面(奇數斷面)、Ⅱ斷面(偶數斷面)、加(jia)強斷面(偶數斷管管片(pian)）

3、波(bo)紋管(guan)(guan)(guan)拼裝(zhuang)(zhuang)(zhuang)(zhuang)：采用刻(ke)(ke)槽法(fa)施工的(de)地(di)基，安(an)(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)吊車依據刻(ke)(ke)槽深度，依次安(an)(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)底部管(guan)(guan)(guan)片(pian)。底部管(guan)(guan)(guan)片(pian)安(an)(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)完(wan)成后對剩余管(guan)(guan)(guan)片(pian)進行安(an)(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)。管(guan)(guan)(guan)片(pian)安(an)(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)同平基上的(de)鋼波(bo)紋管(guan)(guan)(guan)施工。

首圈(quan)波(bo)(bo)(bo)紋(wen)管(guan)(guan)圈(quan)為(wei)奇數斷(duan)面，拼裝(zhuang)(zhuang)(zhuang)時應將(jiang)管(guan)(guan)片(pian)立于(yu)地上(shang)(shang)安(an)裝(zhuang)(zhuang)(zhuang)，使(shi)用(yong)(yong)(yong)鐵(tie)鉤的(de)(de)(de)(de)一(yi)端勾住I斷(duan)面片(pian)(1#管(guan)(guan)片(pian))波(bo)(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)螺絲(si)囗，用(yong)(yong)(yong)12噸的(de)(de)(de)(de)吊車(che)勾住鐵(tie)鉤的(de)(de)(de)(de)另(ling)一(yi)端，將(jiang)波(bo)(bo)(bo)紋(wen)管(guan)(guan)片(pian)立于(yu)墊(dian)(dian)層上(shang)(shang)，然后使(shi)用(yong)(yong)(yong)同(tong)樣的(de)(de)(de)(de)辦法將(jiang)第(di)二片(pian)(6#管(guan)(guan)片(pian))波(bo)(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)按圖(tu)3、21斷(duan)面所示的(de)(de)(de)(de)搭接(jie)方式(shi)放置(zhi)，使(shi)用(yong)(yong)(yong)撬(qiao)棍將(jiang)管(guan)(guan)片(pian)的(de)(de)(de)(de)螺栓(shuan)口(kou)對齊，將(jiang)提前準備(bei)好的(de)(de)(de)(de)螺栓(shuan)螺紋(wen)部(bu)涂上(shang)(shang)渢(feng)滑劑，由(you)內冋外(wai)插入孔位(wei)；波(bo)(bo)(bo)紋(wen)管(guan)(guan)外(wai)側(ce)套上(shang)(shang)凹墊(dian)(dian)圈(quan)或凸(tu)墊(dian)(dian)圈(quan)，遇(yu)波(bo)(bo)(bo)使(shi)用(yong)(yong)(yong)凸(tu)墊(dian)(dian)圈(quan)，遇(yu)波(bo)(bo)(bo)峰使(shi)用(yong)(yong)(yong)凹墊(dian)(dian)圈(quan)墊(dian)(dian)圈(quan)外(wai)側(ce)旋上(shang)(shang)螺母(mu)，在用(yong)(yong)(yong)套筒扳手預緊(jin)螺母(mu)，然后使(shi)用(yong)(yong)(yong)電動(dong)扳手緊(jin)固螺母(mu)兩塊板片(pian)洤(quan)全部(bu)安(an)裝(zhuang)(zhuang)(zhuang)完畢;波(bo)(bo)(bo)紋(wen)管(guan)(guan)的(de)(de)(de)(de)螺栓(shuan)安(an)裝(zhuang)(zhuang)(zhuang)完畢后，需采用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠槍于(yu)端部(bu)接(jie)合處(chu)、緊(jin)回(hui)件連接(jie)的(de)(de)(de)(de)螺栓(shuan)孔空隙(xi)處(chu)涂抹(mo)中(zhong)性硅(gui)酮耐候膠。緊(jin)接(jie)著(zhu)按2#管(guan)(guan)片(pian)、5#管(guan)(guan)片(pian)、3#管(guan)(guan)片(pian)、4#管(guan)(guan)片(pian)的(de)(de)(de)(de)施工拼裝(zhuang)(zhuang)(zhuang)順序，拼裝(zhuang)(zhuang)(zhuang)好首圈(quan)波(bo)(bo)(bo)紋(wen)管(guan)(guan)圖(tu)36偶數、奇數斷(duan)面交替拼裝(zhuang)(zhuang)(zhuang)順序

4、加強斷面拼裝

當波紋管涵直徑(jing)較大、填(tian)土(tu)高(gao)度(du)較高(gao)時(shi)，必(bi)須設(she)置加(jia)(jia)強(qiang)管片(pian)(pian)，稱為(wei)加(jia)(jia)強(qiang)圈(quan)”，加(jia)(jia)強(qiang)斷(duan)面的管片(pian)(pian)安裝工序。
