大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝支架(jia):搭(da)設(she)腳(jiao)(jiao)(jiao)手架(jia)根據波(bo)紋管(guan)的直徑提前(qian)確(que)(que)定，采(cai)用管(guan)扣(kou)連接鋼管(guan)的方式搭(da)設(she)腳(jiao)(jiao)(jiao)手架(jia)，形式分A型(xing)和B型(xing)腳(jiao)(jiao)(jiao)手架(jia)長度一般長25m、克0、6m、高(gao)為(wei)2d3(d為(wei)波(bo)紋管(guan)直徑)，B型(xing)腳(jiao)(jiao)(jiao)手架(jia)一般克為(wei)25m高(gao)依據波(bo)紋管(guan)直徑大小拼裝接縫位置確(que)(que)定尺(chi)寸。腳(jiao)(jiao)(jiao)手架(jia)按上述尺(chi)寸搭(da)設(she)便于施工、

2、拼裝(zhuang)類型(xing)與搭接方式：拼裝(zhuang)以中(zhong)心軸線為基(ji)準(zhun)，由中(zhong)心向兩端對(dui)稱進行安裝(zhuang)，直(zhi)至兩端。1斷(duan)面(mian)(mian)(奇數斷(duan)面(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(偶數斷(duan)面(mian)(mian))、加強斷(duan)面(mian)(mian)(偶數斷(duan)管管片）

3、波紋(wen)管(guan)拼裝(zhuang)：采用刻(ke)槽法施(shi)工的地基，安裝(zhuang)吊車依據刻(ke)槽深度，依次安裝(zhuang)底部管(guan)片。底部管(guan)片安裝(zhuang)完成后對剩余管(guan)片進行安裝(zhuang)。管(guan)片安裝(zhuang)同平基上的鋼(gang)波紋(wen)管(guan)施(shi)工。

首(shou)圈(quan)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圈(quan)為奇數斷(duan)(duan)面(mian)，拼(pin)裝(zhuang)時應將(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立(li)于(yu)地上安(an)裝(zhuang)，使(shi)用(yong)鐵(tie)鉤的(de)一端勾(gou)住(zhu)I斷(duan)(duan)面(mian)片(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)絲囗(wei)，用(yong)12噸的(de)吊車勾(gou)住(zhu)鐵(tie)鉤的(de)另一端，將(jiang)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立(li)于(yu)墊(dian)層上，然后使(shi)用(yong)同樣的(de)辦法將(jiang)第二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)按(an)圖3、21斷(duan)(duan)面(mian)所示的(de)搭接(jie)方(fang)式(shi)放置，使(shi)用(yong)撬棍(gun)將(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)螺(luo)(luo)栓口對齊，將(jiang)提前準備好(hao)(hao)的(de)螺(luo)(luo)栓螺(luo)(luo)紋(wen)(wen)(wen)(wen)部(bu)(bu)涂上渢滑劑，由內冋外插入孔位；波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)外側套上凹(ao)墊(dian)圈(quan)或凸(tu)墊(dian)圈(quan)，遇波(bo)(bo)(bo)使(shi)用(yong)凸(tu)墊(dian)圈(quan)，遇波(bo)(bo)(bo)峰使(shi)用(yong)凹(ao)墊(dian)圈(quan)墊(dian)圈(quan)外側旋上螺(luo)(luo)母，在用(yong)套筒扳手預(yu)緊(jin)螺(luo)(luo)母，然后使(shi)用(yong)電動扳手緊(jin)固螺(luo)(luo)母兩塊(kuai)板片(pian)(pian)(pian)(pian)洤(quan)全部(bu)(bu)安(an)裝(zhuang)完畢(bi);波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)的(de)螺(luo)(luo)栓安(an)裝(zhuang)完畢(bi)后，需采用(yong)專(zhuan)用(yong)注(zhu)膠(jiao)槍于(yu)端部(bu)(bu)接(jie)合(he)處、緊(jin)回件連(lian)接(jie)的(de)螺(luo)(luo)栓孔空(kong)隙處涂抹中性硅酮(tong)耐(nai)候(hou)膠(jiao)。緊(jin)接(jie)著按(an)2#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)施工拼(pin)裝(zhuang)順(shun)序(xu)，拼(pin)裝(zhuang)好(hao)(hao)首(shou)圈(quan)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圖36偶(ou)數、奇數斷(duan)(duan)面(mian)交(jiao)替(ti)拼(pin)裝(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當波紋管涵直(zhi)徑(jing)較(jiao)大、填土高度較(jiao)高時(shi)，必須設(she)置加強管片，稱為(wei)加強圈”，加強斷(duan)面的管片安(an)裝工序。
