大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)(she)拼裝支架:搭(da)設(she)(she)腳(jiao)手(shou)(shou)架根據(ju)波紋(wen)管(guan)的(de)直徑(jing)提前確(que)定，采用管(guan)扣(kou)連接(jie)鋼管(guan)的(de)方(fang)式搭(da)設(she)(she)腳(jiao)手(shou)(shou)架，形(xing)式分A型(xing)和B型(xing)腳(jiao)手(shou)(shou)架長度一(yi)般長25m、克(ke)0、6m、高為2d3(d為波紋(wen)管(guan)直徑(jing))，B型(xing)腳(jiao)手(shou)(shou)架一(yi)般克(ke)為25m高依據(ju)波紋(wen)管(guan)直徑(jing)大小拼裝接(jie)縫位置(zhi)確(que)定尺寸。腳(jiao)手(shou)(shou)架按上述尺寸搭(da)設(she)(she)便于施工(gong)、

2、拼裝(zhuang)類型與(yu)搭(da)接方式(shi)：拼裝(zhuang)以中心軸線為基(ji)準，由中心向兩端(duan)(duan)對稱進行安裝(zhuang)，直至兩端(duan)(duan)。1斷(duan)(duan)面(mian)(奇數斷(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)面(mian)(偶數斷(duan)(duan)面(mian))、加強斷(duan)(duan)面(mian)(偶數斷(duan)(duan)管管片）

3、波紋(wen)管(guan)(guan)拼裝(zhuang)：采用刻槽法施(shi)工(gong)的(de)(de)地基(ji)，安(an)裝(zhuang)吊車依(yi)據刻槽深度，依(yi)次安(an)裝(zhuang)底部管(guan)(guan)片。底部管(guan)(guan)片安(an)裝(zhuang)完成后(hou)對剩余管(guan)(guan)片進行(xing)安(an)裝(zhuang)。管(guan)(guan)片安(an)裝(zhuang)同平基(ji)上(shang)的(de)(de)鋼(gang)波紋(wen)管(guan)(guan)施(shi)工(gong)。

首圈(quan)波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)圈(quan)為奇數(shu)斷面(mian)，拼(pin)(pin)裝(zhuang)(zhuang)時(shi)應(ying)將(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)立于地上安(an)裝(zhuang)(zhuang)，使用(yong)(yong)(yong)(yong)(yong)鐵鉤的(de)一端(duan)勾住(zhu)I斷面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)螺(luo)絲囗，用(yong)(yong)(yong)(yong)(yong)12噸的(de)吊(diao)車勾住(zhu)鐵鉤的(de)另一端(duan)，將(jiang)(jiang)波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)立于墊(dian)層上，然后使用(yong)(yong)(yong)(yong)(yong)同樣的(de)辦法將(jiang)(jiang)第二片(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)按(an)圖(tu)3、21斷面(mian)所示的(de)搭接(jie)方式放置，使用(yong)(yong)(yong)(yong)(yong)撬棍將(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)的(de)螺(luo)栓口對(dui)齊，將(jiang)(jiang)提前準備好的(de)螺(luo)栓螺(luo)紋部(bu)涂上渢滑劑，由內冋外(wai)插入孔位(wei)；波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)外(wai)側套上凹墊(dian)圈(quan)或凸(tu)墊(dian)圈(quan)，遇波(bo)(bo)(bo)(bo)使用(yong)(yong)(yong)(yong)(yong)凸(tu)墊(dian)圈(quan)，遇波(bo)(bo)(bo)(bo)峰使用(yong)(yong)(yong)(yong)(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外(wai)側旋上螺(luo)母(mu)，在用(yong)(yong)(yong)(yong)(yong)套筒扳(ban)(ban)手預(yu)緊螺(luo)母(mu)，然后使用(yong)(yong)(yong)(yong)(yong)電動扳(ban)(ban)手緊固(gu)螺(luo)母(mu)兩塊板片(pian)(pian)洤(quan)全部(bu)安(an)裝(zhuang)(zhuang)完(wan)畢;波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)的(de)螺(luo)栓安(an)裝(zhuang)(zhuang)完(wan)畢后，需采用(yong)(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)(yong)注膠槍于端(duan)部(bu)接(jie)合處、緊回(hui)件連接(jie)的(de)螺(luo)栓孔空(kong)隙處涂抹中性(xing)硅酮耐候(hou)膠。緊接(jie)著按(an)2#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)的(de)施工拼(pin)(pin)裝(zhuang)(zhuang)順序(xu)，拼(pin)(pin)裝(zhuang)(zhuang)好首圈(quan)波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)圖(tu)36偶數(shu)、奇數(shu)斷面(mian)交(jiao)替拼(pin)(pin)裝(zhuang)(zhuang)順序(xu)

4、加強斷面拼裝

當(dang)波紋管涵直徑較大、填土高度較高時，必(bi)須設置加(jia)強管片，稱為加(jia)強圈”，加(jia)強斷面的管片安裝工序。
