大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝(zhuang)支架:搭設(she)腳(jiao)(jiao)手架根(gen)據(ju)波紋管(guan)(guan)的直徑提前確(que)定，采用管(guan)(guan)扣(kou)連接(jie)鋼管(guan)(guan)的方式搭設(she)腳(jiao)(jiao)手架，形式分(fen)A型(xing)和B型(xing)腳(jiao)(jiao)手架長(chang)度(du)一般長(chang)25m、克0、6m、高(gao)為2d3(d為波紋管(guan)(guan)直徑)，B型(xing)腳(jiao)(jiao)手架一般克為25m高(gao)依據(ju)波紋管(guan)(guan)直徑大小拼裝(zhuang)接(jie)縫(feng)位置確(que)定尺(chi)寸(cun)。腳(jiao)(jiao)手架按上(shang)述尺(chi)寸(cun)搭設(she)便于施工、

2、拼(pin)裝類(lei)型與搭(da)接方式：拼(pin)裝以中(zhong)心(xin)軸(zhou)線為基準，由中(zhong)心(xin)向(xiang)兩(liang)端對稱(cheng)進行安裝，直至兩(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(guan)管(guan)片(pian)）

3、波紋(wen)管(guan)(guan)(guan)拼(pin)裝(zhuang)(zhuang)：采用(yong)刻槽法施(shi)工的(de)地基，安裝(zhuang)(zhuang)吊車依據(ju)刻槽深度，依次(ci)安裝(zhuang)(zhuang)底(di)部管(guan)(guan)(guan)片。底(di)部管(guan)(guan)(guan)片安裝(zhuang)(zhuang)完成后對(dui)剩余管(guan)(guan)(guan)片進行安裝(zhuang)(zhuang)。管(guan)(guan)(guan)片安裝(zhuang)(zhuang)同(tong)平基上的(de)鋼波紋(wen)管(guan)(guan)(guan)施(shi)工。

首圈(quan)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)圈(quan)為奇數斷(duan)面(mian)(mian)，拼(pin)裝(zhuang)時應將(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于(yu)(yu)地上安(an)裝(zhuang)，使(shi)用(yong)(yong)鐵鉤的一端(duan)勾住I斷(duan)面(mian)(mian)片(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)絲囗，用(yong)(yong)12噸的吊車(che)勾住鐵鉤的另一端(duan)，將(jiang)(jiang)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于(yu)(yu)墊(dian)層上，然后(hou)使(shi)用(yong)(yong)同樣的辦法將(jiang)(jiang)第二片(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)按圖(tu)3、21斷(duan)面(mian)(mian)所示的搭接(jie)方式放置，使(shi)用(yong)(yong)撬(qiao)棍(gun)將(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的螺(luo)栓口對齊，將(jiang)(jiang)提前(qian)準備好的螺(luo)栓螺(luo)紋(wen)(wen)(wen)部(bu)涂(tu)上渢滑劑，由內冋外插入孔(kong)位；波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)外側套上凹(ao)墊(dian)圈(quan)或凸墊(dian)圈(quan)，遇波(bo)(bo)使(shi)用(yong)(yong)凸墊(dian)圈(quan)，遇波(bo)(bo)峰使(shi)用(yong)(yong)凹(ao)墊(dian)圈(quan)墊(dian)圈(quan)外側旋上螺(luo)母(mu)(mu)，在用(yong)(yong)套筒扳手預(yu)緊螺(luo)母(mu)(mu)，然后(hou)使(shi)用(yong)(yong)電(dian)動扳手緊固螺(luo)母(mu)(mu)兩(liang)塊板(ban)片(pian)(pian)(pian)洤全部(bu)安(an)裝(zhuang)完畢(bi);波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)的螺(luo)栓安(an)裝(zhuang)完畢(bi)后(hou)，需采(cai)用(yong)(yong)專用(yong)(yong)注(zhu)膠(jiao)槍(qiang)于(yu)(yu)端(duan)部(bu)接(jie)合處、緊回件連接(jie)的螺(luo)栓孔(kong)空隙處涂(tu)抹中性硅酮耐候(hou)膠(jiao)。緊接(jie)著按2#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的施工(gong)拼(pin)裝(zhuang)順(shun)序，拼(pin)裝(zhuang)好首圈(quan)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)圖(tu)36偶(ou)數、奇數斷(duan)面(mian)(mian)交替拼(pin)裝(zhuang)順(shun)序

4、加強斷面拼裝

當波紋管涵直徑較(jiao)大(da)、填(tian)土高度較(jiao)高時，必須設置加(jia)強管片(pian)，稱為加(jia)強圈”，加(jia)強斷(duan)面的管片(pian)安裝工序。
