大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼裝支架(jia):搭(da)(da)設腳(jiao)(jiao)手架(jia)根(gen)據波(bo)紋(wen)管(guan)的直徑(jing)提前(qian)確(que)定(ding)，采用管(guan)扣連接(jie)鋼(gang)管(guan)的方式(shi)搭(da)(da)設腳(jiao)(jiao)手架(jia)，形式(shi)分A型和B型腳(jiao)(jiao)手架(jia)長度一(yi)般(ban)長25m、克(ke)0、6m、高為2d3(d為波(bo)紋(wen)管(guan)直徑(jing))，B型腳(jiao)(jiao)手架(jia)一(yi)般(ban)克(ke)為25m高依據波(bo)紋(wen)管(guan)直徑(jing)大小拼裝接(jie)縫位(wei)置確(que)定(ding)尺寸(cun)。腳(jiao)(jiao)手架(jia)按上述尺寸(cun)搭(da)(da)設便于(yu)施工(gong)、

2、拼裝類型與搭接方式：拼裝以中心軸(zhou)線為基(ji)準，由中心向兩(liang)端對稱進行安裝，直至兩(liang)端。1斷(duan)面(mian)(奇數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數斷(duan)面(mian))、加強斷(duan)面(mian)(偶數斷(duan)管(guan)管(guan)片(pian)）

3、波紋(wen)管(guan)拼(pin)裝(zhuang)(zhuang)：采用(yong)刻槽法施(shi)工的地(di)基(ji)(ji)，安裝(zhuang)(zhuang)吊車依(yi)(yi)據刻槽深(shen)度，依(yi)(yi)次(ci)安裝(zhuang)(zhuang)底(di)部管(guan)片(pian)。底(di)部管(guan)片(pian)安裝(zhuang)(zhuang)完成后(hou)對剩余管(guan)片(pian)進(jin)行(xing)安裝(zhuang)(zhuang)。管(guan)片(pian)安裝(zhuang)(zhuang)同平基(ji)(ji)上的鋼(gang)波紋(wen)管(guan)施(shi)工。

首圈(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)圈(quan)為奇數(shu)斷面，拼裝(zhuang)時應將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于地上安(an)裝(zhuang)，使用(yong)鐵鉤的(de)(de)(de)(de)(de)一端勾住I斷面片(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)絲囗，用(yong)12噸的(de)(de)(de)(de)(de)吊車勾住鐵鉤的(de)(de)(de)(de)(de)另一端，將(jiang)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于墊層上，然(ran)后使用(yong)同樣的(de)(de)(de)(de)(de)辦法將(jiang)第二片(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)按圖3、21斷面所示的(de)(de)(de)(de)(de)搭(da)接(jie)方式放置(zhi)，使用(yong)撬(qiao)棍將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)(de)(de)螺(luo)栓口對齊(qi)，將(jiang)提前準備好的(de)(de)(de)(de)(de)螺(luo)栓螺(luo)紋(wen)部(bu)涂上渢滑劑(ji)，由(you)內冋外插(cha)入孔(kong)位；波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)外側(ce)套上凹墊圈(quan)或凸(tu)墊圈(quan)，遇(yu)波(bo)(bo)使用(yong)凸(tu)墊圈(quan)，遇(yu)波(bo)(bo)峰使用(yong)凹墊圈(quan)墊圈(quan)外側(ce)旋(xuan)上螺(luo)母(mu)，在用(yong)套筒(tong)扳手預緊(jin)(jin)螺(luo)母(mu)，然(ran)后使用(yong)電動扳手緊(jin)(jin)固螺(luo)母(mu)兩塊板片(pian)(pian)(pian)洤全部(bu)安(an)裝(zhuang)完(wan)(wan)畢;波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)(de)螺(luo)栓安(an)裝(zhuang)完(wan)(wan)畢后，需采用(yong)專(zhuan)用(yong)注(zhu)膠槍于端部(bu)接(jie)合處、緊(jin)(jin)回件連接(jie)的(de)(de)(de)(de)(de)螺(luo)栓孔(kong)空隙處涂抹中性硅酮(tong)耐候膠。緊(jin)(jin)接(jie)著按2#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)(de)(de)施工拼裝(zhuang)順序(xu)，拼裝(zhuang)好首圈(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)圖36偶數(shu)、奇數(shu)斷面交替(ti)拼裝(zhuang)順序(xu)

4、加強斷面拼裝

當波(bo)紋管涵(han)直徑(jing)較(jiao)大、填土高(gao)(gao)度較(jiao)高(gao)(gao)時，必(bi)須設置加強(qiang)管片(pian)，稱為加強(qiang)圈”，加強(qiang)斷面的管片(pian)安裝工序(xu)。
