大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)(she)拼(pin)裝支架:搭設(she)(she)腳(jiao)手架根據波(bo)紋管(guan)(guan)的(de)直徑提前確(que)定，采用管(guan)(guan)扣(kou)連接(jie)鋼管(guan)(guan)的(de)方式(shi)搭設(she)(she)腳(jiao)手架，形式(shi)分A型和B型腳(jiao)手架長度一(yi)般(ban)長25m、克0、6m、高為2d3(d為波(bo)紋管(guan)(guan)直徑)，B型腳(jiao)手架一(yi)般(ban)克為25m高依據波(bo)紋管(guan)(guan)直徑大小拼(pin)裝接(jie)縫位置確(que)定尺寸(cun)。腳(jiao)手架按上(shang)述尺寸(cun)搭設(she)(she)便于(yu)施(shi)工、

2、拼裝(zhuang)類型與搭接方式：拼裝(zhuang)以中(zhong)心軸(zhou)線為(wei)基準(zhun)，由(you)中(zhong)心向兩端對稱進行安裝(zhuang)，直至兩端。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(jia)強斷(duan)面(mian)(mian)(偶數(shu)斷(duan)管管片）

3、波紋(wen)管(guan)(guan)拼裝(zhuang)：采(cai)用刻(ke)槽法施工的(de)地(di)基，安(an)(an)裝(zhuang)吊車依(yi)據刻(ke)槽深度，依(yi)次安(an)(an)裝(zhuang)底部管(guan)(guan)片。底部管(guan)(guan)片安(an)(an)裝(zhuang)完成后對剩(sheng)余(yu)管(guan)(guan)片進(jin)行安(an)(an)裝(zhuang)。管(guan)(guan)片安(an)(an)裝(zhuang)同平基上的(de)鋼波紋(wen)管(guan)(guan)施工。

首圈(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)圈(quan)為奇數(shu)斷面(mian)，拼裝(zhuang)(zhuang)時應將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于地上(shang)(shang)安裝(zhuang)(zhuang)，使(shi)用(yong)鐵鉤的(de)一端勾(gou)住I斷面(mian)片(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)絲(si)囗(wei)，用(yong)12噸的(de)吊車勾(gou)住鐵鉤的(de)另一端，將(jiang)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于墊(dian)層上(shang)(shang)，然后使(shi)用(yong)同樣的(de)辦(ban)法(fa)將(jiang)第二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)按圖3、21斷面(mian)所示的(de)搭(da)接方(fang)式放(fang)置，使(shi)用(yong)撬棍將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)螺(luo)栓口對齊，將(jiang)提(ti)前準備好(hao)的(de)螺(luo)栓螺(luo)紋(wen)部涂上(shang)(shang)渢滑劑，由內冋(jiong)外(wai)插入孔位；波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)外(wai)側套(tao)上(shang)(shang)凹墊(dian)圈(quan)或凸墊(dian)圈(quan)，遇(yu)波(bo)(bo)使(shi)用(yong)凸墊(dian)圈(quan)，遇(yu)波(bo)(bo)峰使(shi)用(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外(wai)側旋(xuan)上(shang)(shang)螺(luo)母，在用(yong)套(tao)筒扳(ban)手(shou)預(yu)緊螺(luo)母，然后使(shi)用(yong)電動扳(ban)手(shou)緊固螺(luo)母兩塊板片(pian)(pian)(pian)(pian)洤全部安裝(zhuang)(zhuang)完畢;波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)的(de)螺(luo)栓安裝(zhuang)(zhuang)完畢后，需采(cai)用(yong)專用(yong)注(zhu)膠槍(qiang)于端部接合處、緊回(hui)件連接的(de)螺(luo)栓孔空隙處涂抹(mo)中性硅(gui)酮耐候膠。緊接著(zhu)按2#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)施(shi)工拼裝(zhuang)(zhuang)順序，拼裝(zhuang)(zhuang)好(hao)首圈(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)圖36偶數(shu)、奇數(shu)斷面(mian)交替拼裝(zhuang)(zhuang)順序

4、加強斷面拼裝

當波(bo)紋管涵直徑較(jiao)(jiao)大、填土高(gao)度較(jiao)(jiao)高(gao)時(shi)，必(bi)須(xu)設置加強管片(pian)，稱為加強圈”，加強斷面的管片(pian)安裝工序。
