大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼(pin)裝(zhuang)支架(jia)(jia):搭(da)設(she)腳手架(jia)(jia)根據(ju)(ju)波紋管(guan)(guan)(guan)的(de)直徑(jing)(jing)提前確定(ding)，采用(yong)管(guan)(guan)(guan)扣連(lian)接鋼管(guan)(guan)(guan)的(de)方式搭(da)設(she)腳手架(jia)(jia)，形(xing)式分A型(xing)和(he)B型(xing)腳手架(jia)(jia)長度一般(ban)長25m、克0、6m、高(gao)為2d3(d為波紋管(guan)(guan)(guan)直徑(jing)(jing))，B型(xing)腳手架(jia)(jia)一般(ban)克為25m高(gao)依據(ju)(ju)波紋管(guan)(guan)(guan)直徑(jing)(jing)大小(xiao)拼(pin)裝(zhuang)接縫位置確定(ding)尺寸。腳手架(jia)(jia)按(an)上述尺寸搭(da)設(she)便于施工、

2、拼裝類型與搭接(jie)方(fang)式：拼裝以中心(xin)軸線為基準，由中心(xin)向(xiang)兩端(duan)對(dui)稱(cheng)進行安裝，直(zhi)至(zhi)兩端(duan)。1斷面(奇數(shu)(shu)斷面)、Ⅱ斷面(偶數(shu)(shu)斷面)、加(jia)強斷面(偶數(shu)(shu)斷管管片）

3、波紋(wen)管(guan)拼(pin)裝(zhuang)(zhuang)：采用刻槽(cao)法施工(gong)的(de)(de)地基，安裝(zhuang)(zhuang)吊車依據刻槽(cao)深度，依次安裝(zhuang)(zhuang)底(di)部(bu)管(guan)片(pian)。底(di)部(bu)管(guan)片(pian)安裝(zhuang)(zhuang)完成后(hou)對剩余(yu)管(guan)片(pian)進行(xing)安裝(zhuang)(zhuang)。管(guan)片(pian)安裝(zhuang)(zhuang)同平基上(shang)的(de)(de)鋼波紋(wen)管(guan)施工(gong)。

首(shou)圈(quan)(quan)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)圈(quan)(quan)為奇數斷面(mian)，拼裝(zhuang)時(shi)應將(jiang)(jiang)(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)立(li)于(yu)地上安裝(zhuang)，使(shi)(shi)用鐵鉤的(de)(de)一端(duan)勾住I斷面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)(luo)絲囗，用12噸的(de)(de)吊(diao)車勾住鐵鉤的(de)(de)另一端(duan)，將(jiang)(jiang)(jiang)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)立(li)于(yu)墊(dian)(dian)層上，然后使(shi)(shi)用同樣的(de)(de)辦法(fa)將(jiang)(jiang)(jiang)第二片(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)按圖3、21斷面(mian)所示的(de)(de)搭接方(fang)式(shi)放置，使(shi)(shi)用撬棍將(jiang)(jiang)(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)的(de)(de)螺(luo)(luo)(luo)栓(shuan)(shuan)口對齊，將(jiang)(jiang)(jiang)提前(qian)準備好的(de)(de)螺(luo)(luo)(luo)栓(shuan)(shuan)螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)部涂上渢滑劑，由內冋外(wai)(wai)插入孔位；波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)外(wai)(wai)側套上凹墊(dian)(dian)圈(quan)(quan)或凸(tu)墊(dian)(dian)圈(quan)(quan)，遇波(bo)(bo)使(shi)(shi)用凸(tu)墊(dian)(dian)圈(quan)(quan)，遇波(bo)(bo)峰(feng)使(shi)(shi)用凹墊(dian)(dian)圈(quan)(quan)墊(dian)(dian)圈(quan)(quan)外(wai)(wai)側旋(xuan)上螺(luo)(luo)(luo)母，在用套筒扳手預緊螺(luo)(luo)(luo)母，然后使(shi)(shi)用電動(dong)扳手緊固螺(luo)(luo)(luo)母兩塊板片(pian)(pian)洤全部安裝(zhuang)完畢;波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)的(de)(de)螺(luo)(luo)(luo)栓(shuan)(shuan)安裝(zhuang)完畢后，需采用專用注(zhu)膠(jiao)(jiao)槍于(yu)端(duan)部接合處(chu)、緊回件連接的(de)(de)螺(luo)(luo)(luo)栓(shuan)(shuan)孔空隙處(chu)涂抹中性硅酮(tong)耐候膠(jiao)(jiao)。緊接著(zhu)按2#管(guan)(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)的(de)(de)施(shi)工拼裝(zhuang)順序，拼裝(zhuang)好首(shou)圈(quan)(quan)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)圖36偶數、奇數斷面(mian)交(jiao)替拼裝(zhuang)順序

4、加強斷面拼裝

當波(bo)紋(wen)管涵(han)直徑較大(da)、填土高(gao)度(du)較高(gao)時，必須(xu)設置加強管片，稱為加強圈(quan)”，加強斷(duan)面的管片安裝(zhuang)工序。
