大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝(zhuang)支架:搭設腳(jiao)手(shou)(shou)架根(gen)據波紋(wen)管(guan)的直徑(jing)提前確(que)定，采(cai)用管(guan)扣連接鋼管(guan)的方式搭設腳(jiao)手(shou)(shou)架，形(xing)式分A型和(he)B型腳(jiao)手(shou)(shou)架長度一般長25m、克0、6m、高為2d3(d為波紋(wen)管(guan)直徑(jing))，B型腳(jiao)手(shou)(shou)架一般克為25m高依據波紋(wen)管(guan)直徑(jing)大小拼裝(zhuang)接縫位(wei)置(zhi)確(que)定尺(chi)寸(cun)(cun)。腳(jiao)手(shou)(shou)架按上(shang)述尺(chi)寸(cun)(cun)搭設便于施工、

2、拼(pin)裝(zhuang)類型與搭接(jie)方式(shi)：拼(pin)裝(zhuang)以中心(xin)軸(zhou)線為基準(zhun)，由中心(xin)向兩(liang)端對稱進(jin)行安裝(zhuang)，直(zhi)至兩(liang)端。1斷(duan)(duan)(duan)面(奇(qi)數(shu)斷(duan)(duan)(duan)面)、Ⅱ斷(duan)(duan)(duan)面(偶數(shu)斷(duan)(duan)(duan)面)、加(jia)強斷(duan)(duan)(duan)面(偶數(shu)斷(duan)(duan)(duan)管管片）

3、波紋管(guan)(guan)拼裝：采用刻(ke)槽法施工(gong)的地基(ji)，安裝吊車依(yi)據刻(ke)槽深度，依(yi)次安裝底部管(guan)(guan)片(pian)。底部管(guan)(guan)片(pian)安裝完成后對剩余管(guan)(guan)片(pian)進行安裝。管(guan)(guan)片(pian)安裝同平基(ji)上的鋼(gang)波紋管(guan)(guan)施工(gong)。

鋼波紋管

首圈(quan)(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)圈(quan)(quan)為奇數(shu)斷面(mian)，拼(pin)(pin)裝(zhuang)時應將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于地上(shang)(shang)(shang)安(an)裝(zhuang)，使(shi)用(yong)(yong)鐵鉤的(de)(de)一(yi)端勾住I斷面(mian)片(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)絲囗，用(yong)(yong)12噸(dun)的(de)(de)吊車(che)勾住鐵鉤的(de)(de)另一(yi)端，將(jiang)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于墊(dian)(dian)(dian)層上(shang)(shang)(shang)，然(ran)后使(shi)用(yong)(yong)同樣的(de)(de)辦法將(jiang)第(di)二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)按圖3、21斷面(mian)所示的(de)(de)搭接(jie)方式(shi)放(fang)置，使(shi)用(yong)(yong)撬棍(gun)將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)螺(luo)栓口對齊，將(jiang)提前(qian)準備(bei)好的(de)(de)螺(luo)栓螺(luo)紋(wen)(wen)部(bu)涂上(shang)(shang)(shang)渢(feng)滑(hua)劑，由內冋外(wai)插入孔位；波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)外(wai)側套(tao)上(shang)(shang)(shang)凹墊(dian)(dian)(dian)圈(quan)(quan)或凸墊(dian)(dian)(dian)圈(quan)(quan)，遇波(bo)使(shi)用(yong)(yong)凸墊(dian)(dian)(dian)圈(quan)(quan)，遇波(bo)峰使(shi)用(yong)(yong)凹墊(dian)(dian)(dian)圈(quan)(quan)墊(dian)(dian)(dian)圈(quan)(quan)外(wai)側旋(xuan)上(shang)(shang)(shang)螺(luo)母(mu)，在用(yong)(yong)套(tao)筒扳手(shou)預緊(jin)(jin)(jin)螺(luo)母(mu)，然(ran)后使(shi)用(yong)(yong)電(dian)動扳手(shou)緊(jin)(jin)(jin)固螺(luo)母(mu)兩塊板片(pian)(pian)(pian)(pian)洤全(quan)部(bu)安(an)裝(zhuang)完畢(bi);波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)的(de)(de)螺(luo)栓安(an)裝(zhuang)完畢(bi)后，需采(cai)用(yong)(yong)專(zhuan)用(yong)(yong)注膠槍于端部(bu)接(jie)合處、緊(jin)(jin)(jin)回件連接(jie)的(de)(de)螺(luo)栓孔空隙處涂抹中性硅酮(tong)耐候膠。緊(jin)(jin)(jin)接(jie)著(zhu)按2#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)施工(gong)拼(pin)(pin)裝(zhuang)順(shun)序(xu)，拼(pin)(pin)裝(zhuang)好首圈(quan)(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)圖36偶數(shu)、奇數(shu)斷面(mian)交替拼(pin)(pin)裝(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當波紋管(guan)涵直徑較大(da)、填土(tu)高度(du)較高時，必須設置加強管(guan)片，稱(cheng)為加強圈”，加強斷面的管(guan)片安(an)裝工序。
