大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝支架:搭設腳手(shou)(shou)(shou)(shou)架根據波紋管(guan)的直(zhi)徑提(ti)前確定，采用管(guan)扣連接(jie)鋼管(guan)的方式搭設腳手(shou)(shou)(shou)(shou)架，形(xing)式分(fen)A型和B型腳手(shou)(shou)(shou)(shou)架長度一般(ban)長25m、克0、6m、高為(wei)2d3(d為(wei)波紋管(guan)直(zhi)徑)，B型腳手(shou)(shou)(shou)(shou)架一般(ban)克為(wei)25m高依據波紋管(guan)直(zhi)徑大(da)小拼(pin)裝接(jie)縫(feng)位置(zhi)確定尺寸(cun)。腳手(shou)(shou)(shou)(shou)架按上述尺寸(cun)搭設便于施(shi)工、

2、拼(pin)裝(zhuang)(zhuang)類型與搭接方(fang)式：拼(pin)裝(zhuang)(zhuang)以(yi)中心軸(zhou)線為(wei)基(ji)準，由中心向兩端對稱(cheng)進行安(an)裝(zhuang)(zhuang)，直至兩端。1斷面(奇(qi)數斷面)、Ⅱ斷面(偶(ou)數斷面)、加強斷面(偶(ou)數斷管管片）

3、波紋(wen)管(guan)拼(pin)裝(zhuang)：采用刻槽(cao)法(fa)施工(gong)的地基，安(an)裝(zhuang)吊車依據刻槽(cao)深度，依次安(an)裝(zhuang)底(di)部管(guan)片(pian)。底(di)部管(guan)片(pian)安(an)裝(zhuang)完成后對剩余(yu)管(guan)片(pian)進行安(an)裝(zhuang)。管(guan)片(pian)安(an)裝(zhuang)同平基上(shang)的鋼波紋(wen)管(guan)施工(gong)。

首圈(quan)(quan)(quan)波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)圈(quan)(quan)(quan)為奇數(shu)斷面(mian)，拼裝時(shi)應將管(guan)(guan)(guan)片(pian)(pian)立于地上安(an)裝，使(shi)(shi)用(yong)(yong)鐵鉤的(de)(de)(de)一端勾(gou)住(zhu)(zhu)I斷面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)12噸的(de)(de)(de)吊車(che)勾(gou)住(zhu)(zhu)鐵鉤的(de)(de)(de)另一端，將波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)片(pian)(pian)立于墊層上，然后(hou)使(shi)(shi)用(yong)(yong)同樣的(de)(de)(de)辦法將第(di)二(er)片(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)按圖3、21斷面(mian)所示的(de)(de)(de)搭接方(fang)式放置，使(shi)(shi)用(yong)(yong)撬棍將管(guan)(guan)(guan)片(pian)(pian)的(de)(de)(de)螺(luo)(luo)栓(shuan)口對齊，將提前準備好的(de)(de)(de)螺(luo)(luo)栓(shuan)螺(luo)(luo)紋部涂(tu)上渢滑劑，由內冋外插入孔位；波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)外側(ce)套(tao)上凹(ao)(ao)墊圈(quan)(quan)(quan)或凸墊圈(quan)(quan)(quan)，遇(yu)波(bo)(bo)(bo)(bo)使(shi)(shi)用(yong)(yong)凸墊圈(quan)(quan)(quan)，遇(yu)波(bo)(bo)(bo)(bo)峰使(shi)(shi)用(yong)(yong)凹(ao)(ao)墊圈(quan)(quan)(quan)墊圈(quan)(quan)(quan)外側(ce)旋上螺(luo)(luo)母，在用(yong)(yong)套(tao)筒扳手(shou)(shou)預(yu)緊螺(luo)(luo)母，然后(hou)使(shi)(shi)用(yong)(yong)電動扳手(shou)(shou)緊固(gu)螺(luo)(luo)母兩塊板片(pian)(pian)洤(quan)全部安(an)裝完(wan)畢;波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)的(de)(de)(de)螺(luo)(luo)栓(shuan)安(an)裝完(wan)畢后(hou)，需采用(yong)(yong)專用(yong)(yong)注膠(jiao)槍(qiang)于端部接合(he)處(chu)、緊回件連接的(de)(de)(de)螺(luo)(luo)栓(shuan)孔空(kong)隙(xi)處(chu)涂(tu)抹中(zhong)性硅酮耐候膠(jiao)。緊接著按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)(de)(de)施工拼裝順序，拼裝好首圈(quan)(quan)(quan)波(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)圖36偶(ou)數(shu)、奇數(shu)斷面(mian)交(jiao)替(ti)拼裝順序

4、加強斷面拼裝

當波紋管(guan)涵直徑較大(da)、填土(tu)高度較高時，必須設置加(jia)強管(guan)片(pian)，稱為(wei)加(jia)強圈(quan)”，加(jia)強斷面(mian)的管(guan)片(pian)安(an)裝工序。
