大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝(zhuang)支架(jia):搭設腳(jiao)手(shou)架(jia)根據(ju)波紋(wen)管(guan)的直(zhi)徑提前確(que)定，采用管(guan)扣(kou)連接鋼(gang)管(guan)的方式搭設腳(jiao)手(shou)架(jia)，形式分A型和(he)B型腳(jiao)手(shou)架(jia)長度(du)一(yi)般長25m、克0、6m、高(gao)為2d3(d為波紋(wen)管(guan)直(zhi)徑)，B型腳(jiao)手(shou)架(jia)一(yi)般克為25m高(gao)依據(ju)波紋(wen)管(guan)直(zhi)徑大小拼裝(zhuang)接縫位置(zhi)確(que)定尺(chi)寸(cun)(cun)。腳(jiao)手(shou)架(jia)按上述尺(chi)寸(cun)(cun)搭設便于(yu)施工(gong)、

2、拼裝類(lei)型與搭接方式：拼裝以中心軸線為基準，由(you)中心向兩(liang)端對稱進行安裝，直(zhi)至兩(liang)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)管管片）

3、波紋管拼(pin)裝(zhuang)(zhuang)(zhuang)：采用刻槽法施(shi)工的地基(ji)，安(an)裝(zhuang)(zhuang)(zhuang)吊(diao)車依據刻槽深(shen)度，依次安(an)裝(zhuang)(zhuang)(zhuang)底部管片(pian)。底部管片(pian)安(an)裝(zhuang)(zhuang)(zhuang)完成后對(dui)剩(sheng)余管片(pian)進(jin)行安(an)裝(zhuang)(zhuang)(zhuang)。管片(pian)安(an)裝(zhuang)(zhuang)(zhuang)同平基(ji)上的鋼(gang)波紋管施(shi)工。

鋼波紋管

首圈波(bo)(bo)紋(wen)(wen)管(guan)(guan)圈為奇數(shu)斷(duan)面，拼(pin)(pin)(pin)裝時應(ying)將管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于(yu)地上(shang)安裝，使用鐵鉤的(de)(de)一(yi)端勾住(zhu)I斷(duan)面片(pian)(pian)(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)螺(luo)(luo)(luo)絲囗，用12噸的(de)(de)吊(diao)車勾住(zhu)鐵鉤的(de)(de)另一(yi)端，將波(bo)(bo)紋(wen)(wen)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于(yu)墊(dian)(dian)層上(shang)，然后使用同樣的(de)(de)辦法將第二(er)片(pian)(pian)(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)按圖3、21斷(duan)面所示的(de)(de)搭接方(fang)式放(fang)置(zhi)，使用撬棍將管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)螺(luo)(luo)(luo)栓(shuan)口對齊(qi)，將提前準備好的(de)(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋(wen)(wen)部涂上(shang)渢滑劑，由內(nei)冋外插入(ru)孔位；波(bo)(bo)紋(wen)(wen)管(guan)(guan)外側套上(shang)凹墊(dian)(dian)圈或凸墊(dian)(dian)圈，遇(yu)波(bo)(bo)使用凸墊(dian)(dian)圈，遇(yu)波(bo)(bo)峰使用凹墊(dian)(dian)圈墊(dian)(dian)圈外側旋上(shang)螺(luo)(luo)(luo)母，在用套筒(tong)扳手預(yu)緊螺(luo)(luo)(luo)母，然后使用電動扳手緊固螺(luo)(luo)(luo)母兩塊板片(pian)(pian)(pian)(pian)(pian)洤全部安裝完(wan)畢;波(bo)(bo)紋(wen)(wen)管(guan)(guan)的(de)(de)螺(luo)(luo)(luo)栓(shuan)安裝完(wan)畢后，需采用專用注膠(jiao)(jiao)槍于(yu)端部接合處(chu)、緊回件連接的(de)(de)螺(luo)(luo)(luo)栓(shuan)孔空(kong)隙處(chu)涂抹中性硅(gui)酮耐候(hou)膠(jiao)(jiao)。緊接著(zhu)按2#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、5#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、3#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、4#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)施工拼(pin)(pin)(pin)裝順(shun)序，拼(pin)(pin)(pin)裝好首圈波(bo)(bo)紋(wen)(wen)管(guan)(guan)圖36偶數(shu)、奇數(shu)斷(duan)面交替(ti)拼(pin)(pin)(pin)裝順(shun)序

4、加強斷面拼裝

當波紋(wen)管(guan)涵直徑較大、填土高度較高時，必(bi)須設置加(jia)強(qiang)管(guan)片，稱為加(jia)強(qiang)圈”，加(jia)強(qiang)斷(duan)面(mian)的管(guan)片安裝工序。
