大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)拼(pin)裝支(zhi)架(jia):搭(da)(da)設(she)腳(jiao)手(shou)架(jia)根據波紋(wen)管的直徑提前確定，采用管扣連接鋼管的方式搭(da)(da)設(she)腳(jiao)手(shou)架(jia)，形式分A型和B型腳(jiao)手(shou)架(jia)長度(du)一般(ban)長25m、克0、6m、高(gao)為(wei)2d3(d為(wei)波紋(wen)管直徑)，B型腳(jiao)手(shou)架(jia)一般(ban)克為(wei)25m高(gao)依據波紋(wen)管直徑大小拼(pin)裝接縫位置(zhi)確定尺(chi)寸(cun)。腳(jiao)手(shou)架(jia)按上(shang)述尺(chi)寸(cun)搭(da)(da)設(she)便于施工、

2、拼裝(zhuang)類型與(yu)搭接方(fang)式：拼裝(zhuang)以中(zhong)心(xin)軸線為基準，由中(zhong)心(xin)向兩(liang)端對稱進行安裝(zhuang)，直至(zhi)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(qiang)斷(duan)面(mian)(偶數斷(duan)管(guan)管(guan)片）

3、波紋管(guan)(guan)拼裝(zhuang)：采用刻槽法施工的地(di)基(ji)，安裝(zhuang)吊(diao)車依據(ju)刻槽深度，依次(ci)安裝(zhuang)底部管(guan)(guan)片(pian)。底部管(guan)(guan)片(pian)安裝(zhuang)完成后對剩余管(guan)(guan)片(pian)進行安裝(zhuang)。管(guan)(guan)片(pian)安裝(zhuang)同(tong)平基(ji)上的鋼波紋管(guan)(guan)施工。

首圈(quan)波(bo)紋(wen)(wen)(wen)管(guan)圈(quan)為奇(qi)數(shu)斷(duan)(duan)面(mian)，拼裝(zhuang)(zhuang)時應將(jiang)管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)立(li)于(yu)地(di)上(shang)安(an)(an)裝(zhuang)(zhuang)，使用(yong)(yong)(yong)鐵(tie)鉤(gou)的(de)(de)一端勾住(zhu)I斷(duan)(duan)面(mian)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(1#管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)螺絲(si)囗，用(yong)(yong)(yong)12噸的(de)(de)吊車勾住(zhu)鐵(tie)鉤(gou)的(de)(de)另一端，將(jiang)波(bo)紋(wen)(wen)(wen)管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)立(li)于(yu)墊(dian)(dian)(dian)層上(shang)，然(ran)后(hou)使用(yong)(yong)(yong)同樣的(de)(de)辦法將(jiang)第二(er)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(6#管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)按圖(tu)3、21斷(duan)(duan)面(mian)所(suo)示(shi)的(de)(de)搭接(jie)方式(shi)放置，使用(yong)(yong)(yong)撬(qiao)棍將(jiang)管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)的(de)(de)螺栓口對齊(qi)，將(jiang)提前準備(bei)好(hao)的(de)(de)螺栓螺紋(wen)(wen)(wen)部涂(tu)上(shang)渢(feng)滑劑，由內冋外插(cha)入孔位；波(bo)紋(wen)(wen)(wen)管(guan)外側套(tao)上(shang)凹墊(dian)(dian)(dian)圈(quan)或(huo)凸(tu)墊(dian)(dian)(dian)圈(quan)，遇(yu)波(bo)使用(yong)(yong)(yong)凸(tu)墊(dian)(dian)(dian)圈(quan)，遇(yu)波(bo)峰使用(yong)(yong)(yong)凹墊(dian)(dian)(dian)圈(quan)墊(dian)(dian)(dian)圈(quan)外側旋上(shang)螺母(mu)(mu)，在用(yong)(yong)(yong)套(tao)筒(tong)扳手(shou)預(yu)緊(jin)螺母(mu)(mu)，然(ran)后(hou)使用(yong)(yong)(yong)電動扳手(shou)緊(jin)固螺母(mu)(mu)兩塊板片(pian)(pian)(pian)(pian)(pian)(pian)(pian)洤(quan)全部安(an)(an)裝(zhuang)(zhuang)完畢;波(bo)紋(wen)(wen)(wen)管(guan)的(de)(de)螺栓安(an)(an)裝(zhuang)(zhuang)完畢后(hou)，需(xu)采用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠槍于(yu)端部接(jie)合處、緊(jin)回件連接(jie)的(de)(de)螺栓孔空隙處涂(tu)抹中性硅酮耐候膠。緊(jin)接(jie)著按2#管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)、5#管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)、3#管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)、4#管(guan)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)的(de)(de)施工(gong)拼裝(zhuang)(zhuang)順(shun)(shun)序(xu)，拼裝(zhuang)(zhuang)好(hao)首圈(quan)波(bo)紋(wen)(wen)(wen)管(guan)圖(tu)36偶數(shu)、奇(qi)數(shu)斷(duan)(duan)面(mian)交替拼裝(zhuang)(zhuang)順(shun)(shun)序(xu)

4、加強斷面拼裝

當波(bo)紋管涵(han)直徑較(jiao)大、填土高度較(jiao)高時，必須設(she)置加強管片，稱為加強圈”，加強斷面(mian)的管片安裝(zhuang)工序(xu)。
