大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼裝支架(jia):搭(da)設腳(jiao)(jiao)手架(jia)根(gen)據(ju)波(bo)紋管(guan)(guan)的直(zhi)徑(jing)提前確定，采(cai)用(yong)管(guan)(guan)扣連接鋼管(guan)(guan)的方式(shi)搭(da)設腳(jiao)(jiao)手架(jia)，形式(shi)分A型(xing)和(he)B型(xing)腳(jiao)(jiao)手架(jia)長度一(yi)般長25m、克(ke)0、6m、高為2d3(d為波(bo)紋管(guan)(guan)直(zhi)徑(jing))，B型(xing)腳(jiao)(jiao)手架(jia)一(yi)般克(ke)為25m高依據(ju)波(bo)紋管(guan)(guan)直(zhi)徑(jing)大小拼裝接縫(feng)位(wei)置確定尺寸。腳(jiao)(jiao)手架(jia)按(an)上述尺寸搭(da)設便于(yu)施工、

2、拼裝(zhuang)類型與搭(da)接(jie)方式：拼裝(zhuang)以(yi)中心(xin)軸線為基(ji)準，由中心(xin)向兩(liang)端對稱進行(xing)安裝(zhuang)，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(guan)管(guan)片）

3、波紋(wen)管拼裝：采用刻槽(cao)法施(shi)工的地基，安(an)裝吊車依據刻槽(cao)深度，依次(ci)安(an)裝底(di)部管片(pian)(pian)(pian)。底(di)部管片(pian)(pian)(pian)安(an)裝完成后對剩余管片(pian)(pian)(pian)進行安(an)裝。管片(pian)(pian)(pian)安(an)裝同平基上的鋼波紋(wen)管施(shi)工。

鋼波紋管

首(shou)圈(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圈(quan)為奇數(shu)斷(duan)面(mian)，拼裝時應將(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)立于(yu)地(di)上(shang)(shang)安裝，使(shi)用(yong)(yong)鐵鉤的(de)一端(duan)勾(gou)住I斷(duan)面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)螺(luo)絲(si)囗，用(yong)(yong)12噸的(de)吊車勾(gou)住鐵鉤的(de)另一端(duan)，將(jiang)(jiang)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)立于(yu)墊(dian)(dian)層上(shang)(shang)，然后使(shi)用(yong)(yong)同(tong)樣的(de)辦法將(jiang)(jiang)第(di)二片(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)按(an)圖3、21斷(duan)面(mian)所示的(de)搭接方(fang)式放置，使(shi)用(yong)(yong)撬棍(gun)將(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)的(de)螺(luo)栓口對齊，將(jiang)(jiang)提(ti)前(qian)準備(bei)好的(de)螺(luo)栓螺(luo)紋(wen)(wen)(wen)部(bu)涂(tu)(tu)上(shang)(shang)渢(feng)滑劑(ji)，由內冋外(wai)(wai)插入孔(kong)(kong)位；波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)外(wai)(wai)側套(tao)上(shang)(shang)凹墊(dian)(dian)圈(quan)或(huo)凸(tu)墊(dian)(dian)圈(quan)，遇波(bo)使(shi)用(yong)(yong)凸(tu)墊(dian)(dian)圈(quan)，遇波(bo)峰使(shi)用(yong)(yong)凹墊(dian)(dian)圈(quan)墊(dian)(dian)圈(quan)外(wai)(wai)側旋上(shang)(shang)螺(luo)母，在用(yong)(yong)套(tao)筒扳手預緊螺(luo)母，然后使(shi)用(yong)(yong)電(dian)動扳手緊固螺(luo)母兩塊(kuai)板片(pian)(pian)洤全部(bu)安裝完(wan)畢;波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)的(de)螺(luo)栓安裝完(wan)畢后，需采用(yong)(yong)專用(yong)(yong)注膠槍(qiang)于(yu)端(duan)部(bu)接合處、緊回件連接的(de)螺(luo)栓孔(kong)(kong)空隙處涂(tu)(tu)抹中性硅酮耐候(hou)膠。緊接著按(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)施工拼裝順序，拼裝好首(shou)圈(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圖36偶數(shu)、奇數(shu)斷(duan)面(mian)交替拼裝順序

4、加強斷面拼裝

當波(bo)紋管涵直徑較(jiao)大、填(tian)土高(gao)度較(jiao)高(gao)時，必(bi)須設置加強(qiang)管片(pian)，稱為加強(qiang)圈”，加強(qiang)斷面的管片(pian)安裝工序。
