大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)拼裝支架(jia):搭(da)(da)設(she)腳(jiao)(jiao)手(shou)架(jia)根據波紋(wen)管(guan)(guan)的直(zhi)徑(jing)提(ti)前確(que)定，采用管(guan)(guan)扣連(lian)接鋼管(guan)(guan)的方式搭(da)(da)設(she)腳(jiao)(jiao)手(shou)架(jia)，形(xing)式分A型和(he)B型腳(jiao)(jiao)手(shou)架(jia)長(chang)度一般(ban)長(chang)25m、克(ke)(ke)0、6m、高為2d3(d為波紋(wen)管(guan)(guan)直(zhi)徑(jing))，B型腳(jiao)(jiao)手(shou)架(jia)一般(ban)克(ke)(ke)為25m高依據波紋(wen)管(guan)(guan)直(zhi)徑(jing)大(da)小拼裝接縫位置確(que)定尺(chi)寸。腳(jiao)(jiao)手(shou)架(jia)按(an)上述尺(chi)寸搭(da)(da)設(she)便于施(shi)工、

2、拼(pin)裝(zhuang)類型與搭接方式(shi)：拼(pin)裝(zhuang)以中心軸線為基準，由中心向兩(liang)(liang)端對稱進行安裝(zhuang)，直至兩(liang)(liang)端。1斷(duan)(duan)面(mian)(奇數(shu)斷(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)面(mian)(偶數(shu)斷(duan)(duan)面(mian))、加強斷(duan)(duan)面(mian)(偶數(shu)斷(duan)(duan)管(guan)管(guan)片）

3、波(bo)紋管拼裝(zhuang)(zhuang)：采用刻(ke)(ke)槽法施工的地基，安裝(zhuang)(zhuang)吊車(che)依據刻(ke)(ke)槽深度(du)，依次安裝(zhuang)(zhuang)底部管片(pian)。底部管片(pian)安裝(zhuang)(zhuang)完成后對剩余管片(pian)進行安裝(zhuang)(zhuang)。管片(pian)安裝(zhuang)(zhuang)同平基上的鋼波(bo)紋管施工。

首圈(quan)波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)圈(quan)為奇(qi)數斷面，拼(pin)裝時應將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于(yu)地上(shang)(shang)安(an)裝，使(shi)用鐵鉤(gou)的(de)(de)一(yi)端(duan)勾(gou)住I斷面片(pian)(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)螺(luo)(luo)(luo)(luo)(luo)(luo)絲囗，用12噸(dun)的(de)(de)吊車勾(gou)住鐵鉤(gou)的(de)(de)另一(yi)端(duan)，將(jiang)波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于(yu)墊(dian)(dian)層上(shang)(shang)，然(ran)后(hou)使(shi)用同樣的(de)(de)辦法將(jiang)第二片(pian)(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)按(an)圖(tu)(tu)3、21斷面所示的(de)(de)搭接方式放置，使(shi)用撬棍(gun)將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)螺(luo)(luo)(luo)(luo)(luo)(luo)栓口(kou)對齊，將(jiang)提前準備好的(de)(de)螺(luo)(luo)(luo)(luo)(luo)(luo)栓螺(luo)(luo)(luo)(luo)(luo)(luo)紋(wen)(wen)部涂上(shang)(shang)渢滑劑，由內(nei)冋外插(cha)入孔(kong)位；波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)外側套上(shang)(shang)凹墊(dian)(dian)圈(quan)或凸墊(dian)(dian)圈(quan)，遇波(bo)(bo)(bo)(bo)使(shi)用凸墊(dian)(dian)圈(quan)，遇波(bo)(bo)(bo)(bo)峰(feng)使(shi)用凹墊(dian)(dian)圈(quan)墊(dian)(dian)圈(quan)外側旋上(shang)(shang)螺(luo)(luo)(luo)(luo)(luo)(luo)母，在用套筒扳(ban)手預緊(jin)螺(luo)(luo)(luo)(luo)(luo)(luo)母，然(ran)后(hou)使(shi)用電(dian)動扳(ban)手緊(jin)固螺(luo)(luo)(luo)(luo)(luo)(luo)母兩塊板(ban)片(pian)(pian)(pian)(pian)(pian)洤全部安(an)裝完畢;波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)的(de)(de)螺(luo)(luo)(luo)(luo)(luo)(luo)栓安(an)裝完畢后(hou)，需采用專(zhuan)用注膠槍(qiang)于(yu)端(duan)部接合處、緊(jin)回件連接的(de)(de)螺(luo)(luo)(luo)(luo)(luo)(luo)栓孔(kong)空隙(xi)處涂抹中(zhong)性硅酮耐候膠。緊(jin)接著按(an)2#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)施(shi)工拼(pin)裝順序，拼(pin)裝好首圈(quan)波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)圖(tu)(tu)36偶數、奇(qi)數斷面交(jiao)替拼(pin)裝順序

4、加強斷面拼裝

當波紋管(guan)涵(han)直徑較(jiao)大、填(tian)土(tu)高度較(jiao)高時，必須(xu)設置加(jia)(jia)強(qiang)(qiang)管(guan)片，稱為加(jia)(jia)強(qiang)(qiang)圈”，加(jia)(jia)強(qiang)(qiang)斷面的管(guan)片安裝工序。
