大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)(she)拼裝支架:搭(da)(da)設(she)(she)腳手(shou)(shou)(shou)架根據(ju)(ju)波紋(wen)管(guan)(guan)(guan)的直徑(jing)提前(qian)確(que)定，采用管(guan)(guan)(guan)扣連接鋼管(guan)(guan)(guan)的方(fang)式搭(da)(da)設(she)(she)腳手(shou)(shou)(shou)架，形式分(fen)A型和B型腳手(shou)(shou)(shou)架長度一般長25m、克0、6m、高為(wei)2d3(d為(wei)波紋(wen)管(guan)(guan)(guan)直徑(jing))，B型腳手(shou)(shou)(shou)架一般克為(wei)25m高依據(ju)(ju)波紋(wen)管(guan)(guan)(guan)直徑(jing)大小拼裝接縫位置確(que)定尺寸(cun)。腳手(shou)(shou)(shou)架按上述(shu)尺寸(cun)搭(da)(da)設(she)(she)便(bian)于(yu)施工、

2、拼(pin)裝類型與搭接(jie)方式：拼(pin)裝以(yi)中(zhong)心軸線為基準，由中(zhong)心向兩端對稱進行安裝，直(zhi)至兩端。1斷(duan)面(mian)(奇數(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數(shu)斷(duan)面(mian))、加強(qiang)斷(duan)面(mian)(偶數(shu)斷(duan)管管片）

3、波紋(wen)管(guan)(guan)(guan)拼(pin)裝(zhuang)(zhuang)：采用(yong)刻槽(cao)法施工的(de)地(di)基(ji)(ji)，安裝(zhuang)(zhuang)吊車依據刻槽(cao)深度，依次(ci)安裝(zhuang)(zhuang)底部(bu)管(guan)(guan)(guan)片。底部(bu)管(guan)(guan)(guan)片安裝(zhuang)(zhuang)完成(cheng)后對剩余管(guan)(guan)(guan)片進行(xing)安裝(zhuang)(zhuang)。管(guan)(guan)(guan)片安裝(zhuang)(zhuang)同平基(ji)(ji)上的(de)鋼波紋(wen)管(guan)(guan)(guan)施工。

首圈(quan)(quan)波(bo)(bo)紋(wen)管(guan)圈(quan)(quan)為奇數斷(duan)面，拼(pin)裝(zhuang)時(shi)應將管(guan)片(pian)(pian)(pian)立于地(di)上(shang)安裝(zhuang)，使用(yong)鐵鉤(gou)的(de)一端(duan)勾住I斷(duan)面片(pian)(pian)(pian)(1#管(guan)片(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)管(guan)片(pian)(pian)(pian)螺(luo)(luo)絲囗，用(yong)12噸的(de)吊(diao)車(che)勾住鐵鉤(gou)的(de)另一端(duan)，將波(bo)(bo)紋(wen)管(guan)片(pian)(pian)(pian)立于墊(dian)層(ceng)上(shang)，然后(hou)使用(yong)同樣(yang)的(de)辦(ban)法將第(di)二片(pian)(pian)(pian)(6#管(guan)片(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)管(guan)片(pian)(pian)(pian)按圖3、21斷(duan)面所示的(de)搭接(jie)方式放置，使用(yong)撬(qiao)棍將管(guan)片(pian)(pian)(pian)的(de)螺(luo)(luo)栓口對齊，將提前準備好的(de)螺(luo)(luo)栓螺(luo)(luo)紋(wen)部(bu)(bu)涂上(shang)渢滑劑，由內冋(jiong)外插入(ru)孔位；波(bo)(bo)紋(wen)管(guan)外側(ce)套上(shang)凹墊(dian)圈(quan)(quan)或凸墊(dian)圈(quan)(quan)，遇(yu)波(bo)(bo)使用(yong)凸墊(dian)圈(quan)(quan)，遇(yu)波(bo)(bo)峰使用(yong)凹墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外側(ce)旋上(shang)螺(luo)(luo)母，在用(yong)套筒扳手(shou)預(yu)緊螺(luo)(luo)母，然后(hou)使用(yong)電(dian)動扳手(shou)緊固(gu)螺(luo)(luo)母兩塊板(ban)片(pian)(pian)(pian)洤全(quan)部(bu)(bu)安裝(zhuang)完(wan)(wan)畢;波(bo)(bo)紋(wen)管(guan)的(de)螺(luo)(luo)栓安裝(zhuang)完(wan)(wan)畢后(hou)，需采(cai)用(yong)專用(yong)注膠槍(qiang)于端(duan)部(bu)(bu)接(jie)合處、緊回件連接(jie)的(de)螺(luo)(luo)栓孔空隙(xi)處涂抹中性(xing)硅酮耐候膠。緊接(jie)著(zhu)按2#管(guan)片(pian)(pian)(pian)、5#管(guan)片(pian)(pian)(pian)、3#管(guan)片(pian)(pian)(pian)、4#管(guan)片(pian)(pian)(pian)的(de)施工拼(pin)裝(zhuang)順序，拼(pin)裝(zhuang)好首圈(quan)(quan)波(bo)(bo)紋(wen)管(guan)圖36偶(ou)數、奇數斷(duan)面交替拼(pin)裝(zhuang)順序

4、加強斷面拼裝

當(dang)波紋(wen)管涵直徑較大、填(tian)土高度較高時，必須設置(zhi)加強管片，稱(cheng)為加強圈(quan)”，加強斷面的管片安裝工序。
