大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝支架(jia):搭(da)設(she)腳(jiao)(jiao)手(shou)(shou)架(jia)根據波紋管(guan)(guan)的(de)直徑提前(qian)確定，采用(yong)管(guan)(guan)扣連接鋼管(guan)(guan)的(de)方式搭(da)設(she)腳(jiao)(jiao)手(shou)(shou)架(jia)，形式分(fen)A型(xing)和B型(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)長(chang)(chang)度一般(ban)(ban)長(chang)(chang)25m、克0、6m、高為2d3(d為波紋管(guan)(guan)直徑)，B型(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)一般(ban)(ban)克為25m高依據波紋管(guan)(guan)直徑大(da)小拼裝接縫位置確定尺(chi)寸。腳(jiao)(jiao)手(shou)(shou)架(jia)按上(shang)述尺(chi)寸搭(da)設(she)便(bian)于施工、

2、拼(pin)裝(zhuang)類型與搭接方(fang)式：拼(pin)裝(zhuang)以中心(xin)軸(zhou)線為(wei)基(ji)準(zhun)，由中心(xin)向(xiang)兩端對(dui)稱進行安裝(zhuang)，直(zhi)至兩端。1斷(duan)(duan)(duan)面(奇(qi)數斷(duan)(duan)(duan)面)、Ⅱ斷(duan)(duan)(duan)面(偶(ou)數斷(duan)(duan)(duan)面)、加強(qiang)斷(duan)(duan)(duan)面(偶(ou)數斷(duan)(duan)(duan)管管片）

3、波紋管拼裝(zhuang)(zhuang)：采用(yong)刻槽法施(shi)工(gong)的(de)地基(ji)，安裝(zhuang)(zhuang)吊(diao)車依(yi)據刻槽深度，依(yi)次安裝(zhuang)(zhuang)底部管片(pian)。底部管片(pian)安裝(zhuang)(zhuang)完成(cheng)后對剩余管片(pian)進行安裝(zhuang)(zhuang)。管片(pian)安裝(zhuang)(zhuang)同平基(ji)上的(de)鋼波紋管施(shi)工(gong)。

首(shou)圈(quan)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圈(quan)為奇數斷面(mian)，拼(pin)裝(zhuang)(zhuang)時(shi)應(ying)將管(guan)(guan)(guan)(guan)(guan)片(pian)立于地上(shang)安(an)裝(zhuang)(zhuang)，使(shi)(shi)用鐵鉤的(de)一端(duan)勾住I斷面(mian)片(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian))波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)螺(luo)(luo)絲囗，用12噸的(de)吊車勾住鐵鉤的(de)另一端(duan)，將波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)片(pian)立于墊層上(shang)，然(ran)后(hou)使(shi)(shi)用同樣的(de)辦法將第二片(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian))波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)按圖(tu)3、21斷面(mian)所示(shi)的(de)搭接(jie)方(fang)式(shi)放(fang)置(zhi)，使(shi)(shi)用撬棍將管(guan)(guan)(guan)(guan)(guan)片(pian)的(de)螺(luo)(luo)栓(shuan)(shuan)口對齊，將提前準備(bei)好的(de)螺(luo)(luo)栓(shuan)(shuan)螺(luo)(luo)紋(wen)(wen)(wen)(wen)部涂(tu)上(shang)渢滑劑，由(you)內冋外(wai)插入(ru)孔(kong)(kong)位；波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)外(wai)側套上(shang)凹墊圈(quan)或凸墊圈(quan)，遇波(bo)(bo)使(shi)(shi)用凸墊圈(quan)，遇波(bo)(bo)峰使(shi)(shi)用凹墊圈(quan)墊圈(quan)外(wai)側旋上(shang)螺(luo)(luo)母(mu)，在用套筒(tong)扳手預緊(jin)螺(luo)(luo)母(mu)，然(ran)后(hou)使(shi)(shi)用電(dian)動扳手緊(jin)固螺(luo)(luo)母(mu)兩(liang)塊板片(pian)洤全部安(an)裝(zhuang)(zhuang)完畢(bi);波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)的(de)螺(luo)(luo)栓(shuan)(shuan)安(an)裝(zhuang)(zhuang)完畢(bi)后(hou)，需采用專用注膠(jiao)槍(qiang)于端(duan)部接(jie)合處、緊(jin)回件(jian)連(lian)接(jie)的(de)螺(luo)(luo)栓(shuan)(shuan)孔(kong)(kong)空隙處涂(tu)抹中(zhong)性硅酮耐候(hou)膠(jiao)。緊(jin)接(jie)著按2#管(guan)(guan)(guan)(guan)(guan)片(pian)、5#管(guan)(guan)(guan)(guan)(guan)片(pian)、3#管(guan)(guan)(guan)(guan)(guan)片(pian)、4#管(guan)(guan)(guan)(guan)(guan)片(pian)的(de)施工拼(pin)裝(zhuang)(zhuang)順序(xu)(xu)，拼(pin)裝(zhuang)(zhuang)好首(shou)圈(quan)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圖(tu)36偶數、奇數斷面(mian)交(jiao)替拼(pin)裝(zhuang)(zhuang)順序(xu)(xu)

4、加強斷面拼裝

當波紋(wen)管(guan)涵(han)直徑(jing)較大(da)、填土(tu)高(gao)(gao)度較高(gao)(gao)時(shi)，必須設置加(jia)強(qiang)管(guan)片(pian)，稱為加(jia)強(qiang)圈”，加(jia)強(qiang)斷面的管(guan)片(pian)安裝工序。
