大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)(da)設(she)拼(pin)裝(zhuang)(zhuang)支架(jia):搭(da)(da)(da)設(she)腳手(shou)架(jia)根(gen)據波紋管(guan)的直徑(jing)提(ti)前確定，采(cai)用管(guan)扣連接(jie)(jie)鋼管(guan)的方式搭(da)(da)(da)設(she)腳手(shou)架(jia)，形(xing)式分A型(xing)和B型(xing)腳手(shou)架(jia)長(chang)度一般長(chang)25m、克(ke)0、6m、高為2d3(d為波紋管(guan)直徑(jing))，B型(xing)腳手(shou)架(jia)一般克(ke)為25m高依(yi)據波紋管(guan)直徑(jing)大小拼(pin)裝(zhuang)(zhuang)接(jie)(jie)縫位置確定尺(chi)寸(cun)。腳手(shou)架(jia)按上述(shu)尺(chi)寸(cun)搭(da)(da)(da)設(she)便于施工、

2、拼裝(zhuang)類型與(yu)搭接方(fang)式：拼裝(zhuang)以中心軸(zhou)線(xian)為基準，由(you)中心向(xiang)兩(liang)端(duan)對稱(cheng)進行安裝(zhuang)，直至兩(liang)端(duan)。1斷面(mian)(奇數斷面(mian))、Ⅱ斷面(mian)(偶(ou)數斷面(mian))、加強斷面(mian)(偶(ou)數斷管管片）

3、波(bo)紋管(guan)拼裝(zhuang)：采用刻(ke)槽法施工(gong)的地基，安(an)裝(zhuang)吊(diao)車依據刻(ke)槽深度，依次(ci)安(an)裝(zhuang)底部管(guan)片(pian)(pian)(pian)。底部管(guan)片(pian)(pian)(pian)安(an)裝(zhuang)完(wan)成后(hou)對(dui)剩余管(guan)片(pian)(pian)(pian)進行安(an)裝(zhuang)。管(guan)片(pian)(pian)(pian)安(an)裝(zhuang)同平基上的鋼(gang)波(bo)紋管(guan)施工(gong)。

鋼波紋管

首圈(quan)波紋(wen)(wen)管(guan)(guan)(guan)圈(quan)為(wei)奇數斷(duan)(duan)面，拼裝(zhuang)時應(ying)將(jiang)(jiang)管(guan)(guan)(guan)片(pian)立于(yu)(yu)地上(shang)安裝(zhuang)，使(shi)(shi)(shi)用(yong)鐵鉤的(de)(de)(de)一端(duan)(duan)勾住I斷(duan)(duan)面片(pian)(1#管(guan)(guan)(guan)片(pian))波紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)螺(luo)絲(si)囗，用(yong)12噸的(de)(de)(de)吊車勾住鐵鉤的(de)(de)(de)另(ling)一端(duan)(duan)，將(jiang)(jiang)波紋(wen)(wen)管(guan)(guan)(guan)片(pian)立于(yu)(yu)墊(dian)(dian)層上(shang)，然后使(shi)(shi)(shi)用(yong)同樣(yang)的(de)(de)(de)辦法將(jiang)(jiang)第二片(pian)(6#管(guan)(guan)(guan)片(pian))波紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)按圖3、21斷(duan)(duan)面所示的(de)(de)(de)搭接(jie)(jie)方式放置，使(shi)(shi)(shi)用(yong)撬棍將(jiang)(jiang)管(guan)(guan)(guan)片(pian)的(de)(de)(de)螺(luo)栓口對齊，將(jiang)(jiang)提前(qian)準備(bei)好的(de)(de)(de)螺(luo)栓螺(luo)紋(wen)(wen)部涂(tu)上(shang)渢滑(hua)劑，由內冋外插入孔位；波紋(wen)(wen)管(guan)(guan)(guan)外側套上(shang)凹墊(dian)(dian)圈(quan)或凸(tu)墊(dian)(dian)圈(quan)，遇波使(shi)(shi)(shi)用(yong)凸(tu)墊(dian)(dian)圈(quan)，遇波峰使(shi)(shi)(shi)用(yong)凹墊(dian)(dian)圈(quan)墊(dian)(dian)圈(quan)外側旋上(shang)螺(luo)母，在(zai)用(yong)套筒扳手(shou)預緊螺(luo)母，然后使(shi)(shi)(shi)用(yong)電動扳手(shou)緊固螺(luo)母兩塊板(ban)片(pian)洤全部安裝(zhuang)完畢;波紋(wen)(wen)管(guan)(guan)(guan)的(de)(de)(de)螺(luo)栓安裝(zhuang)完畢后，需采用(yong)專用(yong)注膠(jiao)槍于(yu)(yu)端(duan)(duan)部接(jie)(jie)合(he)處、緊回件連接(jie)(jie)的(de)(de)(de)螺(luo)栓孔空(kong)隙處涂(tu)抹中性硅酮(tong)耐候膠(jiao)。緊接(jie)(jie)著按2#管(guan)(guan)(guan)片(pian)、5#管(guan)(guan)(guan)片(pian)、3#管(guan)(guan)(guan)片(pian)、4#管(guan)(guan)(guan)片(pian)的(de)(de)(de)施工拼裝(zhuang)順序，拼裝(zhuang)好首圈(quan)波紋(wen)(wen)管(guan)(guan)(guan)圖36偶數、奇數斷(duan)(duan)面交(jiao)替拼裝(zhuang)順序

4、加強斷面拼裝

當(dang)波紋(wen)管涵(han)直徑較大、填(tian)土(tu)高度較高時，必須(xu)設置加強管片，稱為加強圈”，加強斷面的管片安(an)裝工(gong)序。
