大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)拼裝支架(jia):搭(da)(da)設(she)腳手架(jia)根據(ju)波(bo)紋管(guan)的直(zhi)徑提前確(que)定，采用(yong)管(guan)扣連接(jie)(jie)鋼管(guan)的方式搭(da)(da)設(she)腳手架(jia)，形式分A型和B型腳手架(jia)長度一般(ban)長25m、克(ke)(ke)0、6m、高為2d3(d為波(bo)紋管(guan)直(zhi)徑)，B型腳手架(jia)一般(ban)克(ke)(ke)為25m高依據(ju)波(bo)紋管(guan)直(zhi)徑大(da)小拼裝接(jie)(jie)縫位(wei)置確(que)定尺寸。腳手架(jia)按(an)上述尺寸搭(da)(da)設(she)便于施(shi)工、

2、拼裝類型與搭接方式：拼裝以中心(xin)(xin)軸線為基(ji)準，由中心(xin)(xin)向(xiang)兩端(duan)對稱進(jin)行安裝，直至兩端(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、波紋管(guan)(guan)拼裝：采(cai)用刻槽(cao)法施工的地基(ji)，安(an)裝吊車(che)依據刻槽(cao)深度，依次安(an)裝底部(bu)管(guan)(guan)片(pian)。底部(bu)管(guan)(guan)片(pian)安(an)裝完(wan)成后對剩余(yu)管(guan)(guan)片(pian)進行(xing)安(an)裝。管(guan)(guan)片(pian)安(an)裝同平基(ji)上的鋼波紋管(guan)(guan)施工。

鋼波紋管

首圈波(bo)紋(wen)(wen)管(guan)(guan)(guan)圈為奇(qi)數(shu)斷(duan)(duan)面，拼裝(zhuang)(zhuang)時應將管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于地(di)上(shang)安裝(zhuang)(zhuang)，使用(yong)(yong)鐵(tie)鉤的(de)(de)(de)一端勾住I斷(duan)(duan)面片(pian)(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)12噸的(de)(de)(de)吊(diao)車(che)勾住鐵(tie)鉤的(de)(de)(de)另一端，將波(bo)紋(wen)(wen)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于墊(dian)(dian)(dian)層上(shang)，然后使用(yong)(yong)同樣的(de)(de)(de)辦法將第二片(pian)(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)按(an)(an)圖(tu)3、21斷(duan)(duan)面所示的(de)(de)(de)搭(da)接(jie)(jie)(jie)方式(shi)放置，使用(yong)(yong)撬棍將管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)(shuan)口對齊，將提前準備好的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)(shuan)螺(luo)(luo)紋(wen)(wen)部(bu)涂上(shang)渢滑劑，由內冋(jiong)外插入孔位(wei)；波(bo)紋(wen)(wen)管(guan)(guan)(guan)外側套(tao)上(shang)凹墊(dian)(dian)(dian)圈或凸(tu)墊(dian)(dian)(dian)圈，遇波(bo)使用(yong)(yong)凸(tu)墊(dian)(dian)(dian)圈，遇波(bo)峰使用(yong)(yong)凹墊(dian)(dian)(dian)圈墊(dian)(dian)(dian)圈外側旋上(shang)螺(luo)(luo)母(mu)，在用(yong)(yong)套(tao)筒扳手預緊螺(luo)(luo)母(mu)，然后使用(yong)(yong)電(dian)動扳手緊固螺(luo)(luo)母(mu)兩塊板片(pian)(pian)(pian)(pian)(pian)洤(quan)全部(bu)安裝(zhuang)(zhuang)完畢(bi);波(bo)紋(wen)(wen)管(guan)(guan)(guan)的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)(shuan)安裝(zhuang)(zhuang)完畢(bi)后，需采用(yong)(yong)專用(yong)(yong)注膠(jiao)槍于端部(bu)接(jie)(jie)(jie)合處(chu)、緊回件連接(jie)(jie)(jie)的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)(shuan)孔空隙(xi)處(chu)涂抹中(zhong)性硅(gui)酮耐候膠(jiao)。緊接(jie)(jie)(jie)著按(an)(an)2#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)施(shi)工拼裝(zhuang)(zhuang)順(shun)序(xu)(xu)，拼裝(zhuang)(zhuang)好首圈波(bo)紋(wen)(wen)管(guan)(guan)(guan)圖(tu)36偶數(shu)、奇(qi)數(shu)斷(duan)(duan)面交替拼裝(zhuang)(zhuang)順(shun)序(xu)(xu)

4、加強斷面拼裝

當波紋管涵直徑較(jiao)大、填(tian)土高度較(jiao)高時(shi)，必(bi)須設置加(jia)強管片，稱(cheng)為加(jia)強圈”，加(jia)強斷面的管片安(an)裝工序。
