大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝支架(jia):搭設腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)根據(ju)波(bo)紋(wen)管的直徑(jing)(jing)提前確定，采用管扣連接鋼管的方式搭設腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)，形式分A型(xing)和B型(xing)腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)長度一般長25m、克0、6m、高為(wei)(wei)2d3(d為(wei)(wei)波(bo)紋(wen)管直徑(jing)(jing))，B型(xing)腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)一般克為(wei)(wei)25m高依據(ju)波(bo)紋(wen)管直徑(jing)(jing)大(da)小拼(pin)裝接縫位置(zhi)確定尺(chi)寸(cun)。腳(jiao)(jiao)手(shou)(shou)(shou)架(jia)按上(shang)述尺(chi)寸(cun)搭設便于施工、

2、拼裝(zhuang)(zhuang)類型與搭接(jie)方(fang)式：拼裝(zhuang)(zhuang)以中心(xin)軸線為基準，由中心(xin)向兩端(duan)對稱進(jin)行(xing)安裝(zhuang)(zhuang)，直至兩端(duan)。1斷(duan)面(mian)(mian)(奇(qi)數(shu)斷(duan)面(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(偶數(shu)斷(duan)面(mian)(mian))、加(jia)強斷(duan)面(mian)(mian)(偶數(shu)斷(duan)管(guan)管(guan)片）

3、波(bo)紋管(guan)(guan)拼裝(zhuang)(zhuang)：采用刻(ke)槽法施工的地基(ji)，安裝(zhuang)(zhuang)吊車(che)依(yi)據刻(ke)槽深度，依(yi)次安裝(zhuang)(zhuang)底部管(guan)(guan)片(pian)(pian)。底部管(guan)(guan)片(pian)(pian)安裝(zhuang)(zhuang)完成后(hou)對(dui)剩余管(guan)(guan)片(pian)(pian)進行安裝(zhuang)(zhuang)。管(guan)(guan)片(pian)(pian)安裝(zhuang)(zhuang)同(tong)平基(ji)上的鋼波(bo)紋管(guan)(guan)施工。

首圈(quan)(quan)(quan)波紋(wen)管(guan)(guan)(guan)圈(quan)(quan)(quan)為奇數(shu)(shu)斷(duan)面，拼(pin)裝(zhuang)(zhuang)(zhuang)時應將(jiang)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于(yu)地(di)上(shang)(shang)安裝(zhuang)(zhuang)(zhuang)，使(shi)用(yong)鐵(tie)鉤的(de)(de)一端勾住(zhu)I斷(duan)面片(pian)(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)螺(luo)絲囗(wei)，用(yong)12噸的(de)(de)吊(diao)車勾住(zhu)鐵(tie)鉤的(de)(de)另一端，將(jiang)波紋(wen)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于(yu)墊(dian)層上(shang)(shang)，然后(hou)(hou)使(shi)用(yong)同(tong)樣的(de)(de)辦法將(jiang)第二片(pian)(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)按(an)圖(tu)3、21斷(duan)面所示的(de)(de)搭接(jie)方(fang)式放置(zhi)，使(shi)用(yong)撬(qiao)棍(gun)將(jiang)管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)螺(luo)栓(shuan)口對齊(qi)，將(jiang)提前準(zhun)備好的(de)(de)螺(luo)栓(shuan)螺(luo)紋(wen)部涂(tu)上(shang)(shang)渢滑劑，由內冋(jiong)外插(cha)入孔(kong)(kong)位；波紋(wen)管(guan)(guan)(guan)外側(ce)套上(shang)(shang)凹(ao)墊(dian)圈(quan)(quan)(quan)或凸墊(dian)圈(quan)(quan)(quan)，遇波使(shi)用(yong)凸墊(dian)圈(quan)(quan)(quan)，遇波峰使(shi)用(yong)凹(ao)墊(dian)圈(quan)(quan)(quan)墊(dian)圈(quan)(quan)(quan)外側(ce)旋上(shang)(shang)螺(luo)母，在用(yong)套筒扳手預緊(jin)螺(luo)母，然后(hou)(hou)使(shi)用(yong)電動扳手緊(jin)固螺(luo)母兩塊(kuai)板(ban)片(pian)(pian)(pian)(pian)(pian)洤(quan)全部安裝(zhuang)(zhuang)(zhuang)完畢;波紋(wen)管(guan)(guan)(guan)的(de)(de)螺(luo)栓(shuan)安裝(zhuang)(zhuang)(zhuang)完畢后(hou)(hou)，需采用(yong)專用(yong)注膠(jiao)槍于(yu)端部接(jie)合處、緊(jin)回(hui)件連接(jie)的(de)(de)螺(luo)栓(shuan)孔(kong)(kong)空隙(xi)處涂(tu)抹中性(xing)硅酮耐候膠(jiao)。緊(jin)接(jie)著按(an)2#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)施工(gong)拼(pin)裝(zhuang)(zhuang)(zhuang)順序，拼(pin)裝(zhuang)(zhuang)(zhuang)好首圈(quan)(quan)(quan)波紋(wen)管(guan)(guan)(guan)圖(tu)36偶數(shu)(shu)、奇數(shu)(shu)斷(duan)面交替(ti)拼(pin)裝(zhuang)(zhuang)(zhuang)順序

4、加強斷面拼裝

當波紋管涵直徑(jing)較(jiao)(jiao)大、填土高(gao)度較(jiao)(jiao)高(gao)時，必須(xu)設置(zhi)加(jia)強(qiang)管片，稱為加(jia)強(qiang)圈”，加(jia)強(qiang)斷(duan)面(mian)的管片安裝工序。
