大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝(zhuang)支架(jia):搭設(she)腳手(shou)(shou)(shou)架(jia)根據波紋(wen)(wen)管(guan)(guan)的直徑提前確定，采(cai)用管(guan)(guan)扣連(lian)接(jie)鋼管(guan)(guan)的方式搭設(she)腳手(shou)(shou)(shou)架(jia)，形式分A型和B型腳手(shou)(shou)(shou)架(jia)長(chang)度(du)一般長(chang)25m、克0、6m、高為(wei)2d3(d為(wei)波紋(wen)(wen)管(guan)(guan)直徑)，B型腳手(shou)(shou)(shou)架(jia)一般克為(wei)25m高依據波紋(wen)(wen)管(guan)(guan)直徑大小(xiao)拼裝(zhuang)接(jie)縫位置確定尺寸。腳手(shou)(shou)(shou)架(jia)按上(shang)述尺寸搭設(she)便于施工、

2、拼(pin)裝類(lei)型(xing)與搭接方式(shi)：拼(pin)裝以中心(xin)軸線(xian)為基準，由中心(xin)向(xiang)兩端對稱進行(xing)安裝，直至兩端。1斷(duan)(duan)面(奇數斷(duan)(duan)面)、Ⅱ斷(duan)(duan)面(偶數斷(duan)(duan)面)、加強(qiang)斷(duan)(duan)面(偶數斷(duan)(duan)管管片）

3、波紋管(guan)(guan)(guan)拼裝(zhuang)(zhuang)：采(cai)用刻槽(cao)法施工的(de)地基，安裝(zhuang)(zhuang)吊車(che)依(yi)據(ju)刻槽(cao)深(shen)度，依(yi)次安裝(zhuang)(zhuang)底部(bu)管(guan)(guan)(guan)片(pian)(pian)。底部(bu)管(guan)(guan)(guan)片(pian)(pian)安裝(zhuang)(zhuang)完成(cheng)后對(dui)剩余管(guan)(guan)(guan)片(pian)(pian)進行安裝(zhuang)(zhuang)。管(guan)(guan)(guan)片(pian)(pian)安裝(zhuang)(zhuang)同平基上的(de)鋼波紋管(guan)(guan)(guan)施工。

首(shou)圈波(bo)(bo)紋(wen)管(guan)(guan)(guan)圈為(wei)奇(qi)數斷面(mian)(mian)，拼裝時應將(jiang)(jiang)管(guan)(guan)(guan)片(pian)立于(yu)(yu)地上(shang)安(an)裝，使(shi)(shi)(shi)用(yong)(yong)(yong)鐵(tie)鉤的(de)一(yi)(yi)端勾住I斷面(mian)(mian)片(pian)(1#管(guan)(guan)(guan)片(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)螺(luo)(luo)(luo)(luo)絲囗，用(yong)(yong)(yong)12噸的(de)吊車(che)勾住鐵(tie)鉤的(de)另一(yi)(yi)端，將(jiang)(jiang)波(bo)(bo)紋(wen)管(guan)(guan)(guan)片(pian)立于(yu)(yu)墊(dian)(dian)層上(shang)，然后(hou)使(shi)(shi)(shi)用(yong)(yong)(yong)同樣的(de)辦法將(jiang)(jiang)第二片(pian)(6#管(guan)(guan)(guan)片(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)按(an)圖3、21斷面(mian)(mian)所示的(de)搭接(jie)(jie)方(fang)式(shi)放置(zhi)，使(shi)(shi)(shi)用(yong)(yong)(yong)撬(qiao)棍將(jiang)(jiang)管(guan)(guan)(guan)片(pian)的(de)螺(luo)(luo)(luo)(luo)栓(shuan)口對齊，將(jiang)(jiang)提前準備好的(de)螺(luo)(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)(luo)紋(wen)部(bu)涂(tu)上(shang)渢滑(hua)劑，由內冋(jiong)外(wai)插入孔(kong)位(wei)；波(bo)(bo)紋(wen)管(guan)(guan)(guan)外(wai)側套上(shang)凹墊(dian)(dian)圈或凸(tu)墊(dian)(dian)圈，遇波(bo)(bo)使(shi)(shi)(shi)用(yong)(yong)(yong)凸(tu)墊(dian)(dian)圈，遇波(bo)(bo)峰使(shi)(shi)(shi)用(yong)(yong)(yong)凹墊(dian)(dian)圈墊(dian)(dian)圈外(wai)側旋上(shang)螺(luo)(luo)(luo)(luo)母，在(zai)用(yong)(yong)(yong)套筒(tong)扳(ban)手(shou)預(yu)緊螺(luo)(luo)(luo)(luo)母，然后(hou)使(shi)(shi)(shi)用(yong)(yong)(yong)電(dian)動扳(ban)手(shou)緊固螺(luo)(luo)(luo)(luo)母兩塊板片(pian)洤(quan)全部(bu)安(an)裝完畢;波(bo)(bo)紋(wen)管(guan)(guan)(guan)的(de)螺(luo)(luo)(luo)(luo)栓(shuan)安(an)裝完畢后(hou)，需采用(yong)(yong)(yong)專(zhuan)用(yong)(yong)(yong)注膠槍于(yu)(yu)端部(bu)接(jie)(jie)合(he)處(chu)、緊回件連接(jie)(jie)的(de)螺(luo)(luo)(luo)(luo)栓(shuan)孔(kong)空(kong)隙處(chu)涂(tu)抹中性硅酮耐候(hou)膠。緊接(jie)(jie)著按(an)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)施工拼裝順序，拼裝好首(shou)圈波(bo)(bo)紋(wen)管(guan)(guan)(guan)圖36偶數、奇(qi)數斷面(mian)(mian)交替拼裝順序

4、加強斷面拼裝

當波紋管(guan)涵直徑較大、填土高(gao)度較高(gao)時(shi)，必須(xu)設置加強(qiang)管(guan)片，稱為加強(qiang)圈(quan)”，加強(qiang)斷面的管(guan)片安裝工(gong)序。
