大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)拼(pin)裝支架:搭(da)(da)設(she)腳(jiao)手(shou)架根(gen)據波(bo)(bo)紋管(guan)(guan)的(de)直徑(jing)(jing)提前確定，采用管(guan)(guan)扣(kou)連接(jie)鋼管(guan)(guan)的(de)方式搭(da)(da)設(she)腳(jiao)手(shou)架，形式分(fen)A型和B型腳(jiao)手(shou)架長(chang)度一般(ban)長(chang)25m、克(ke)0、6m、高(gao)為2d3(d為波(bo)(bo)紋管(guan)(guan)直徑(jing)(jing))，B型腳(jiao)手(shou)架一般(ban)克(ke)為25m高(gao)依據波(bo)(bo)紋管(guan)(guan)直徑(jing)(jing)大小拼(pin)裝接(jie)縫位置確定尺(chi)寸。腳(jiao)手(shou)架按上(shang)述尺(chi)寸搭(da)(da)設(she)便于施工、

2、拼裝(zhuang)類(lei)型與搭接方式：拼裝(zhuang)以中心軸線為(wei)基準，由中心向兩(liang)(liang)端(duan)對(dui)稱(cheng)進(jin)行(xing)安(an)裝(zhuang)，直至(zhi)兩(liang)(liang)端(duan)。1斷(duan)(duan)(duan)面(奇數斷(duan)(duan)(duan)面)、Ⅱ斷(duan)(duan)(duan)面(偶數斷(duan)(duan)(duan)面)、加強斷(duan)(duan)(duan)面(偶數斷(duan)(duan)(duan)管管片）

3、波(bo)紋(wen)管(guan)(guan)拼裝：采用(yong)刻槽(cao)法施工的(de)地基(ji)(ji)，安(an)裝吊車(che)依據刻槽(cao)深度，依次安(an)裝底(di)部(bu)管(guan)(guan)片(pian)。底(di)部(bu)管(guan)(guan)片(pian)安(an)裝完成(cheng)后對剩余管(guan)(guan)片(pian)進(jin)行安(an)裝。管(guan)(guan)片(pian)安(an)裝同平基(ji)(ji)上(shang)的(de)鋼波(bo)紋(wen)管(guan)(guan)施工。

首(shou)圈(quan)波(bo)(bo)紋(wen)管(guan)(guan)圈(quan)為(wei)奇數斷(duan)面，拼(pin)裝(zhuang)時應(ying)將管(guan)(guan)片(pian)(pian)(pian)立(li)于(yu)地上安裝(zhuang)，使(shi)(shi)用鐵鉤的(de)(de)(de)一(yi)端勾住I斷(duan)面片(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)螺絲(si)囗，用12噸的(de)(de)(de)吊車勾住鐵鉤的(de)(de)(de)另一(yi)端，將波(bo)(bo)紋(wen)管(guan)(guan)片(pian)(pian)(pian)立(li)于(yu)墊層上，然后(hou)使(shi)(shi)用同樣的(de)(de)(de)辦(ban)法(fa)將第二(er)片(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)按圖3、21斷(duan)面所示的(de)(de)(de)搭接方式(shi)放置(zhi)，使(shi)(shi)用撬棍將管(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)螺栓(shuan)(shuan)口對(dui)齊，將提前(qian)準備(bei)好(hao)(hao)的(de)(de)(de)螺栓(shuan)(shuan)螺紋(wen)部涂上渢滑劑，由內冋(jiong)外插入孔位；波(bo)(bo)紋(wen)管(guan)(guan)外側套上凹(ao)墊圈(quan)或(huo)凸(tu)墊圈(quan)，遇波(bo)(bo)使(shi)(shi)用凸(tu)墊圈(quan)，遇波(bo)(bo)峰使(shi)(shi)用凹(ao)墊圈(quan)墊圈(quan)外側旋上螺母(mu)，在用套筒扳(ban)手預緊螺母(mu)，然后(hou)使(shi)(shi)用電動(dong)扳(ban)手緊固螺母(mu)兩塊板片(pian)(pian)(pian)洤全部安裝(zhuang)完(wan)畢;波(bo)(bo)紋(wen)管(guan)(guan)的(de)(de)(de)螺栓(shuan)(shuan)安裝(zhuang)完(wan)畢后(hou)，需采用專用注膠槍于(yu)端部接合處、緊回件(jian)連(lian)接的(de)(de)(de)螺栓(shuan)(shuan)孔空隙(xi)處涂抹中性硅酮耐候膠。緊接著按2#管(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)施工拼(pin)裝(zhuang)順序，拼(pin)裝(zhuang)好(hao)(hao)首(shou)圈(quan)波(bo)(bo)紋(wen)管(guan)(guan)圖36偶數、奇數斷(duan)面交(jiao)替拼(pin)裝(zhuang)順序

4、加強斷面拼裝

當波(bo)紋管涵直徑較(jiao)大、填土高(gao)度較(jiao)高(gao)時，必須(xu)設置(zhi)加(jia)強管片，稱(cheng)為(wei)加(jia)強圈”，加(jia)強斷(duan)面的(de)管片安(an)裝工序。
