大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝(zhuang)支(zhi)架:搭設(she)腳(jiao)手(shou)架根據波(bo)紋管的直(zhi)(zhi)徑提前(qian)確定，采用管扣連(lian)接鋼管的方式搭設(she)腳(jiao)手(shou)架，形式分A型和B型腳(jiao)手(shou)架長(chang)度(du)一(yi)般長(chang)25m、克(ke)0、6m、高為2d3(d為波(bo)紋管直(zhi)(zhi)徑)，B型腳(jiao)手(shou)架一(yi)般克(ke)為25m高依(yi)據波(bo)紋管直(zhi)(zhi)徑大(da)小拼裝(zhuang)接縫位置(zhi)確定尺寸。腳(jiao)手(shou)架按(an)上述尺寸搭設(she)便于施工、

2、拼裝類型與搭接(jie)方式：拼裝以中心軸(zhou)線(xian)為基準，由(you)中心向兩端(duan)(duan)對稱進行安裝，直至兩端(duan)(duan)。1斷(duan)面(奇數斷(duan)面)、Ⅱ斷(duan)面(偶數斷(duan)面)、加強斷(duan)面(偶數斷(duan)管管片）

3、波紋管(guan)(guan)(guan)拼裝(zhuang)(zhuang)：采(cai)用(yong)刻槽法施(shi)工(gong)的地基，安(an)裝(zhuang)(zhuang)吊車依據刻槽深度，依次(ci)安(an)裝(zhuang)(zhuang)底(di)(di)部管(guan)(guan)(guan)片(pian)。底(di)(di)部管(guan)(guan)(guan)片(pian)安(an)裝(zhuang)(zhuang)完(wan)成后對剩(sheng)余管(guan)(guan)(guan)片(pian)進(jin)行(xing)安(an)裝(zhuang)(zhuang)。管(guan)(guan)(guan)片(pian)安(an)裝(zhuang)(zhuang)同平基上的鋼(gang)波紋管(guan)(guan)(guan)施(shi)工(gong)。

首(shou)圈(quan)(quan)波紋(wen)(wen)管(guan)圈(quan)(quan)為奇數(shu)斷(duan)(duan)面，拼裝(zhuang)(zhuang)(zhuang)(zhuang)時(shi)應將(jiang)(jiang)(jiang)管(guan)片(pian)立于(yu)地(di)上(shang)安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)，使(shi)用(yong)(yong)鐵鉤的(de)(de)(de)一(yi)端勾住I斷(duan)(duan)面片(pian)(1#管(guan)片(pian))波紋(wen)(wen)管(guan)管(guan)片(pian)螺(luo)(luo)絲囗(wei)，用(yong)(yong)12噸的(de)(de)(de)吊(diao)車勾住鐵鉤的(de)(de)(de)另一(yi)端，將(jiang)(jiang)(jiang)波紋(wen)(wen)管(guan)片(pian)立于(yu)墊(dian)(dian)層(ceng)上(shang)，然后使(shi)用(yong)(yong)同(tong)樣(yang)的(de)(de)(de)辦(ban)法(fa)將(jiang)(jiang)(jiang)第二片(pian)(6#管(guan)片(pian))波紋(wen)(wen)管(guan)管(guan)片(pian)按圖(tu)3、21斷(duan)(duan)面所示(shi)的(de)(de)(de)搭接(jie)方式放置，使(shi)用(yong)(yong)撬棍將(jiang)(jiang)(jiang)管(guan)片(pian)的(de)(de)(de)螺(luo)(luo)栓(shuan)口對(dui)齊，將(jiang)(jiang)(jiang)提前準備好(hao)的(de)(de)(de)螺(luo)(luo)栓(shuan)螺(luo)(luo)紋(wen)(wen)部涂上(shang)渢滑劑，由內冋(jiong)外(wai)(wai)插入孔位；波紋(wen)(wen)管(guan)外(wai)(wai)側套上(shang)凹墊(dian)(dian)圈(quan)(quan)或凸墊(dian)(dian)圈(quan)(quan)，遇波使(shi)用(yong)(yong)凸墊(dian)(dian)圈(quan)(quan)，遇波峰使(shi)用(yong)(yong)凹墊(dian)(dian)圈(quan)(quan)墊(dian)(dian)圈(quan)(quan)外(wai)(wai)側旋上(shang)螺(luo)(luo)母(mu)，在用(yong)(yong)套筒扳手預(yu)緊(jin)螺(luo)(luo)母(mu)，然后使(shi)用(yong)(yong)電動扳手緊(jin)固(gu)螺(luo)(luo)母(mu)兩塊板片(pian)洤全(quan)部安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)完畢;波紋(wen)(wen)管(guan)的(de)(de)(de)螺(luo)(luo)栓(shuan)安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)完畢后，需采用(yong)(yong)專用(yong)(yong)注膠槍于(yu)端部接(jie)合處、緊(jin)回件連接(jie)的(de)(de)(de)螺(luo)(luo)栓(shuan)孔空隙處涂抹中性硅酮耐候膠。緊(jin)接(jie)著(zhu)按2#管(guan)片(pian)、5#管(guan)片(pian)、3#管(guan)片(pian)、4#管(guan)片(pian)的(de)(de)(de)施工拼裝(zhuang)(zhuang)(zhuang)(zhuang)順序(xu)，拼裝(zhuang)(zhuang)(zhuang)(zhuang)好(hao)首(shou)圈(quan)(quan)波紋(wen)(wen)管(guan)圖(tu)36偶數(shu)、奇數(shu)斷(duan)(duan)面交替拼裝(zhuang)(zhuang)(zhuang)(zhuang)順序(xu)

4、加強斷面拼裝

當波紋管(guan)涵直徑較大、填土高度較高時，必須設置(zhi)加(jia)(jia)強(qiang)管(guan)片，稱為加(jia)(jia)強(qiang)圈”，加(jia)(jia)強(qiang)斷面的管(guan)片安裝(zhuang)工序。
