大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼(pin)裝支架(jia):搭設(she)腳(jiao)手架(jia)根據波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)的直(zhi)徑(jing)提前確定，采用管(guan)(guan)(guan)(guan)扣連(lian)接鋼(gang)管(guan)(guan)(guan)(guan)的方式(shi)搭設(she)腳(jiao)手架(jia)，形式(shi)分(fen)A型和B型腳(jiao)手架(jia)長度一(yi)般(ban)長25m、克(ke)0、6m、高為(wei)2d3(d為(wei)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)直(zhi)徑(jing))，B型腳(jiao)手架(jia)一(yi)般(ban)克(ke)為(wei)25m高依(yi)據波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)直(zhi)徑(jing)大小拼(pin)裝接縫(feng)位置確定尺(chi)寸。腳(jiao)手架(jia)按上述尺(chi)寸搭設(she)便于施工(gong)、

2、拼(pin)裝(zhuang)類(lei)型與搭接方(fang)式：拼(pin)裝(zhuang)以(yi)中(zhong)心軸線為基準，由中(zhong)心向兩端(duan)對稱進行安(an)裝(zhuang)，直至兩端(duan)。1斷(duan)面(奇數斷(duan)面)、Ⅱ斷(duan)面(偶數斷(duan)面)、加強(qiang)斷(duan)面(偶數斷(duan)管管片）

3、波紋管(guan)(guan)拼裝：采用刻(ke)槽法施工(gong)的(de)地基(ji)，安(an)裝吊車依(yi)據刻(ke)槽深度(du)，依(yi)次安(an)裝底部(bu)管(guan)(guan)片。底部(bu)管(guan)(guan)片安(an)裝完成后對剩余管(guan)(guan)片進行安(an)裝。管(guan)(guan)片安(an)裝同平基(ji)上的(de)鋼波紋管(guan)(guan)施工(gong)。

首圈(quan)(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)圈(quan)(quan)為奇數(shu)(shu)斷面(mian)，拼(pin)(pin)裝(zhuang)(zhuang)時應將管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于地上(shang)安裝(zhuang)(zhuang)，使用(yong)(yong)(yong)鐵(tie)鉤的(de)(de)(de)一(yi)端勾住I斷面(mian)片(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺絲囗，用(yong)(yong)(yong)12噸的(de)(de)(de)吊車(che)勾住鐵(tie)鉤的(de)(de)(de)另一(yi)端，將波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于墊(dian)層上(shang)，然后(hou)使用(yong)(yong)(yong)同(tong)樣的(de)(de)(de)辦法將第二片(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)按圖3、21斷面(mian)所(suo)示的(de)(de)(de)搭接方式放(fang)置，使用(yong)(yong)(yong)撬棍將管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)螺栓口對齊，將提(ti)前準備好的(de)(de)(de)螺栓螺紋(wen)(wen)(wen)部(bu)涂(tu)上(shang)渢(feng)滑劑，由內冋(jiong)外(wai)(wai)插入孔位；波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)外(wai)(wai)側套上(shang)凹(ao)墊(dian)圈(quan)(quan)或凸墊(dian)圈(quan)(quan)，遇(yu)波(bo)使用(yong)(yong)(yong)凸墊(dian)圈(quan)(quan)，遇(yu)波(bo)峰(feng)使用(yong)(yong)(yong)凹(ao)墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外(wai)(wai)側旋上(shang)螺母，在用(yong)(yong)(yong)套筒扳(ban)(ban)手(shou)預緊螺母，然后(hou)使用(yong)(yong)(yong)電動扳(ban)(ban)手(shou)緊固螺母兩塊板片(pian)(pian)(pian)洤全部(bu)安裝(zhuang)(zhuang)完畢(bi);波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)的(de)(de)(de)螺栓安裝(zhuang)(zhuang)完畢(bi)后(hou)，需采(cai)用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠槍(qiang)于端部(bu)接合處、緊回件連(lian)接的(de)(de)(de)螺栓孔空隙處涂(tu)抹中性硅酮耐候(hou)膠。緊接著按2#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)施工拼(pin)(pin)裝(zhuang)(zhuang)順(shun)序(xu)，拼(pin)(pin)裝(zhuang)(zhuang)好首圈(quan)(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)圖36偶數(shu)(shu)、奇數(shu)(shu)斷面(mian)交替拼(pin)(pin)裝(zhuang)(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當波(bo)紋管(guan)涵直徑較(jiao)大、填土(tu)高(gao)度(du)較(jiao)高(gao)時，必須設(she)置加(jia)(jia)強(qiang)管(guan)片，稱為加(jia)(jia)強(qiang)圈”，加(jia)(jia)強(qiang)斷面的管(guan)片安(an)裝工(gong)序。
