大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)拼(pin)裝支架(jia)(jia):搭(da)(da)設(she)腳(jiao)(jiao)(jiao)手架(jia)(jia)根據波(bo)紋(wen)管(guan)(guan)(guan)的直徑(jing)提前確定，采(cai)用(yong)管(guan)(guan)(guan)扣(kou)連接鋼管(guan)(guan)(guan)的方式搭(da)(da)設(she)腳(jiao)(jiao)(jiao)手架(jia)(jia)，形式分(fen)A型和B型腳(jiao)(jiao)(jiao)手架(jia)(jia)長度(du)一般長25m、克(ke)(ke)0、6m、高為2d3(d為波(bo)紋(wen)管(guan)(guan)(guan)直徑(jing))，B型腳(jiao)(jiao)(jiao)手架(jia)(jia)一般克(ke)(ke)為25m高依據波(bo)紋(wen)管(guan)(guan)(guan)直徑(jing)大小(xiao)拼(pin)裝接縫(feng)位置確定尺(chi)寸。腳(jiao)(jiao)(jiao)手架(jia)(jia)按上述尺(chi)寸搭(da)(da)設(she)便(bian)于施工、

2、拼裝類型與(yu)搭接(jie)方式(shi)：拼裝以中(zhong)心(xin)軸線為基(ji)準，由中(zhong)心(xin)向兩端對稱進行安裝，直(zhi)至兩端。1斷(duan)面(奇數(shu)斷(duan)面)、Ⅱ斷(duan)面(偶數(shu)斷(duan)面)、加強(qiang)斷(duan)面(偶數(shu)斷(duan)管管片(pian)）

3、波紋(wen)管(guan)拼裝(zhuang)：采用刻槽(cao)法(fa)施工的地基，安(an)裝(zhuang)吊車依(yi)據刻槽(cao)深度，依(yi)次安(an)裝(zhuang)底(di)部管(guan)片(pian)。底(di)部管(guan)片(pian)安(an)裝(zhuang)完成后對剩(sheng)余(yu)管(guan)片(pian)進行(xing)安(an)裝(zhuang)。管(guan)片(pian)安(an)裝(zhuang)同平(ping)基上(shang)的鋼波紋(wen)管(guan)施工。

首圈(quan)(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)圈(quan)(quan)為(wei)奇(qi)數斷(duan)面(mian)(mian)，拼(pin)裝(zhuang)(zhuang)時應將管(guan)(guan)(guan)片(pian)(pian)立于(yu)地上(shang)安(an)裝(zhuang)(zhuang)，使(shi)用(yong)(yong)鐵(tie)鉤(gou)的(de)一(yi)端勾住I斷(duan)面(mian)(mian)片(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)12噸(dun)的(de)吊(diao)車勾住鐵(tie)鉤(gou)的(de)另一(yi)端，將波(bo)(bo)紋(wen)管(guan)(guan)(guan)片(pian)(pian)立于(yu)墊層上(shang)，然(ran)后使(shi)用(yong)(yong)同樣(yang)的(de)辦法將第二片(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)按圖(tu)3、21斷(duan)面(mian)(mian)所示的(de)搭接(jie)(jie)方(fang)式放置，使(shi)用(yong)(yong)撬棍將管(guan)(guan)(guan)片(pian)(pian)的(de)螺(luo)(luo)栓口對齊(qi)，將提前準備(bei)好的(de)螺(luo)(luo)栓螺(luo)(luo)紋(wen)部涂上(shang)渢(feng)滑劑，由內(nei)冋(jiong)外插入孔位(wei)；波(bo)(bo)紋(wen)管(guan)(guan)(guan)外側套上(shang)凹墊圈(quan)(quan)或(huo)凸墊圈(quan)(quan)，遇波(bo)(bo)使(shi)用(yong)(yong)凸墊圈(quan)(quan)，遇波(bo)(bo)峰使(shi)用(yong)(yong)凹墊圈(quan)(quan)墊圈(quan)(quan)外側旋(xuan)上(shang)螺(luo)(luo)母，在用(yong)(yong)套筒扳(ban)手預緊螺(luo)(luo)母，然(ran)后使(shi)用(yong)(yong)電動扳(ban)手緊固螺(luo)(luo)母兩塊板片(pian)(pian)洤全部安(an)裝(zhuang)(zhuang)完畢(bi);波(bo)(bo)紋(wen)管(guan)(guan)(guan)的(de)螺(luo)(luo)栓安(an)裝(zhuang)(zhuang)完畢(bi)后，需(xu)采用(yong)(yong)專用(yong)(yong)注膠槍于(yu)端部接(jie)(jie)合處、緊回件連接(jie)(jie)的(de)螺(luo)(luo)栓孔空隙處涂抹中性硅酮耐候膠。緊接(jie)(jie)著按2#管(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)的(de)施工拼(pin)裝(zhuang)(zhuang)順(shun)序，拼(pin)裝(zhuang)(zhuang)好首圈(quan)(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)圖(tu)36偶數、奇(qi)數斷(duan)面(mian)(mian)交替拼(pin)裝(zhuang)(zhuang)順(shun)序

4、加強斷面拼裝

當波(bo)紋(wen)管(guan)(guan)涵直徑較(jiao)大、填(tian)土高度(du)較(jiao)高時，必須設(she)置加(jia)(jia)強管(guan)(guan)片(pian)，稱為加(jia)(jia)強圈”，加(jia)(jia)強斷面的(de)管(guan)(guan)片(pian)安裝工序(xu)。
