大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝(zhuang)支(zhi)架(jia)(jia):搭設腳手(shou)架(jia)(jia)根據波紋(wen)(wen)管的直徑(jing)提(ti)前確定(ding)，采用(yong)管扣連接(jie)鋼管的方式(shi)(shi)搭設腳手(shou)架(jia)(jia)，形式(shi)(shi)分A型和B型腳手(shou)架(jia)(jia)長度一般(ban)長25m、克(ke)0、6m、高(gao)為2d3(d為波紋(wen)(wen)管直徑(jing))，B型腳手(shou)架(jia)(jia)一般(ban)克(ke)為25m高(gao)依據波紋(wen)(wen)管直徑(jing)大小(xiao)拼裝(zhuang)接(jie)縫位置確定(ding)尺寸(cun)。腳手(shou)架(jia)(jia)按上(shang)述尺寸(cun)搭設便于施工、

2、拼裝類型(xing)與搭接方(fang)式：拼裝以中心軸線為基準，由中心向兩端(duan)對稱進行安(an)裝，直至兩端(duan)。1斷面(奇數斷面)、Ⅱ斷面(偶數斷面)、加強斷面(偶數斷管(guan)管(guan)片(pian)）

3、波(bo)紋(wen)管(guan)拼裝(zhuang)(zhuang)：采(cai)用(yong)刻槽法施工(gong)的(de)地(di)基，安(an)裝(zhuang)(zhuang)吊車依據(ju)刻槽深度，依次安(an)裝(zhuang)(zhuang)底部(bu)管(guan)片(pian)。底部(bu)管(guan)片(pian)安(an)裝(zhuang)(zhuang)完成后(hou)對(dui)剩余管(guan)片(pian)進行安(an)裝(zhuang)(zhuang)。管(guan)片(pian)安(an)裝(zhuang)(zhuang)同平基上的(de)鋼波(bo)紋(wen)管(guan)施工(gong)。

鋼波紋管

首圈(quan)波(bo)紋(wen)(wen)管(guan)圈(quan)為(wei)奇(qi)數(shu)斷(duan)(duan)面(mian)，拼裝(zhuang)(zhuang)時應將管(guan)片(pian)(pian)立于地上(shang)(shang)安裝(zhuang)(zhuang)，使(shi)(shi)用(yong)(yong)(yong)鐵鉤的(de)(de)一(yi)端勾住I斷(duan)(duan)面(mian)片(pian)(pian)(1#管(guan)片(pian)(pian))波(bo)紋(wen)(wen)管(guan)管(guan)片(pian)(pian)螺(luo)(luo)絲(si)囗(wei)，用(yong)(yong)(yong)12噸的(de)(de)吊(diao)車勾住鐵鉤的(de)(de)另一(yi)端，將波(bo)紋(wen)(wen)管(guan)片(pian)(pian)立于墊(dian)層上(shang)(shang)，然(ran)后(hou)使(shi)(shi)用(yong)(yong)(yong)同樣的(de)(de)辦(ban)法將第(di)二(er)片(pian)(pian)(6#管(guan)片(pian)(pian))波(bo)紋(wen)(wen)管(guan)管(guan)片(pian)(pian)按圖3、21斷(duan)(duan)面(mian)所(suo)示的(de)(de)搭接方式放置，使(shi)(shi)用(yong)(yong)(yong)撬(qiao)棍將管(guan)片(pian)(pian)的(de)(de)螺(luo)(luo)栓(shuan)(shuan)口對齊，將提前準備好(hao)(hao)的(de)(de)螺(luo)(luo)栓(shuan)(shuan)螺(luo)(luo)紋(wen)(wen)部涂上(shang)(shang)渢滑劑，由內冋外(wai)(wai)插入孔位；波(bo)紋(wen)(wen)管(guan)外(wai)(wai)側(ce)套上(shang)(shang)凹墊(dian)圈(quan)或凸(tu)墊(dian)圈(quan)，遇(yu)波(bo)使(shi)(shi)用(yong)(yong)(yong)凸(tu)墊(dian)圈(quan)，遇(yu)波(bo)峰使(shi)(shi)用(yong)(yong)(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外(wai)(wai)側(ce)旋上(shang)(shang)螺(luo)(luo)母(mu)(mu)，在(zai)用(yong)(yong)(yong)套筒扳(ban)手(shou)預緊螺(luo)(luo)母(mu)(mu)，然(ran)后(hou)使(shi)(shi)用(yong)(yong)(yong)電動扳(ban)手(shou)緊固(gu)螺(luo)(luo)母(mu)(mu)兩塊板片(pian)(pian)洤全部安裝(zhuang)(zhuang)完畢;波(bo)紋(wen)(wen)管(guan)的(de)(de)螺(luo)(luo)栓(shuan)(shuan)安裝(zhuang)(zhuang)完畢后(hou)，需采用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠(jiao)槍于端部接合(he)處、緊回(hui)件連接的(de)(de)螺(luo)(luo)栓(shuan)(shuan)孔空隙處涂抹(mo)中性(xing)硅酮(tong)耐候(hou)膠(jiao)。緊接著按2#管(guan)片(pian)(pian)、5#管(guan)片(pian)(pian)、3#管(guan)片(pian)(pian)、4#管(guan)片(pian)(pian)的(de)(de)施工拼裝(zhuang)(zhuang)順序，拼裝(zhuang)(zhuang)好(hao)(hao)首圈(quan)波(bo)紋(wen)(wen)管(guan)圖36偶數(shu)、奇(qi)數(shu)斷(duan)(duan)面(mian)交替拼裝(zhuang)(zhuang)順序

4、加強斷面拼裝

當波紋管(guan)涵直徑較大、填土高度(du)較高時，必須(xu)設置加(jia)強管(guan)片，稱為(wei)加(jia)強圈”，加(jia)強斷(duan)面的管(guan)片安裝(zhuang)工序。
